# Change Log

## Version 3.11.0 - Leafa - in development

### Camera - New Features, Updates and Fixes

* All of the 2D Camera classes are now 100% covered by JSDocs!
* `Camera.alpha` (and its related method `Camera.setAlpha`) allows you to set an alpha level for the entire camera. This impacts everything it is rendering, even if those objects also have their own alpha values too. You can tween the property to make the camera contents fade in / out, or otherwise set it as needed in your game.
* `Camera.deadzone` (and its related method `Camera.setDeadzone`) allows you to specify the deadzone for a camera. The deadzone is a rectangular region used when a camera is following a target. If the target is within the deadzone then the camera will not scroll. As soon as the target leaves the deadzone, the camera will begin tracking it (applying lerp if needed.) It allows you to set a region of the camera in which a player can move freely before tracking begins. The deadzone is re-centered on the camera mid point every frame, meaning you can also use the rectangle for other in-game checks as needed.
* `Camera.pan` is a new Camera Effect that allows you to control automatic camera pans between points in your game world. You can specify a duration and ease type for the pan, and it'll emit events just like all other camera effects, so you can hook into the start, update and completion of the pan. See the examples and docs for more details.
* `Camera.zoom` is a new Camera Effect that allows you to control automatic camera zooming. You can specify a duration and ease type for the zoom, as well as the zoom factor of course, and it'll emit events just like all other camera effects, so you can hook into the start, update and completion of the zoom. Used in combination with the new Pan effect you can zoom and pan around with ease. See the examples and docs for more details.
* `Camera.midPoint` is a new Vec2 property that is updated every frame. Use it to obtain exactly where in the world the center of the camera is currently looking.
* `Camera.displayWidth` is a new property that returns the display width of the camera, factoring in the current zoom level.
* `Camera.displayHeight` is a new property that returns the display height of the camera, factoring in the current zoom level.
* `Camera.centerOn` is a new method that will move the camera so its viewport is centered on the given coordinates. A handy way of jumping to different points around a map without needing to calculate the scroll offsets.
* The Camera bounds didn't factor in the camera zoom properly, meaning you would often not be able to reach the corners of a camera bound world at a zoom level other than 1. The bounds are now calculated each frame to ensure they match the zoom level and it will no longer allow you to scroll off the edge of the bounds. Fix #3547 (thanks @nkholski)
* `Camera.centerToBounds` didn't take the bounds offset into account, so bounds at non-zero positions wouldn't center properly. All bounds now center correctly. Fix #3706 (thanks @cyantree)
* `Camera.setBounds` has a new optional argument `centerOn`. If specified it will automatically center the camera on the new bounds given.
* The Camera will no longer stutter when following Game Objects at high zoom levels.
* `Camera._id` has been renamed to `Camera.id`, a read-only bitmask used for camera exclusion from Game Objects.
* The Camera Manager `cameraPool` has been removed entirely. It was mostly pointless in practice as Cameras are not regenerated frequently enough to need pooling. It also didn't maintain the bitmask list correctly before.
* `CameraManager.resetAll` now destroys all current Cameras, resets the camera ID marker to 1 and adds a single new Camera.
* `CameraManager.currentCameraId` has been removed. IDs are assigned more intelligently now, via the `getNextID` internal method.
* `CameraManager.addExisting` no longer needs to be passed a Camera that already exists in the pool (as the pool has been removed), meaning you can now create your own Cameras and pass them to `addExisting` and have them treated as normal cameras and not be ignored by the manager. They are also assigned a proper ID when added.
* `CameraManager.addExisting` has a new boolean argument `makeMain` which will make the new camera the main one.
* `CameraManager.getTotal` is a new method that will return the total number of Cameras being managed, with an optional `isVisible` argument, that only counts visible cameras if set.
* `CameraManager.remove` can now take an array of cameras to be removed from the manager, as well as a single camera.
* `CameraManager.remove` would previously not allow you to remove a camera if it meant there would be no cameras left in the Camera Manager. This restriction has been removed. A Camera Manager can now run even with zero cameras. Your game obviously won't display anything, but it's still now possible.
* `CameraManager.remove` will now return the total number of Cameras removed.

### Round Pixels Changes

Before explaining the changes it's worth covering what the three different game config properties do:

`roundPixels` - this will cause the renderer to draw most Game Objects at whole integer positions. Their actual positions can be anything, but the renderer will floor the values to ensure they are integers immediately before drawing. It only works on texture based Game Objects. Graphics objects, for instance, ignore this property.

`antialias` - when set to `true` WebGL textures are created using `gl.LINEAR`, which allows WebGL to try its best to interpolate the texture when rendered at non-texture frame sizes. This can happen if you scale a Game Object, or zoom a Camera. In both cases it will need to interpolate the pixel values to accommodate the new size. If this property is set to `false` then it will use `gl.NEAREST` instead. This uses a nearest neighbor method of interpolation, and is nearly always the better option if you need to keep the textures crisp, such as when using scaled pixel art. Disabling `antialias` invokes nearest-neighbor interpolation on the game canvas itself as well. If you need a mixture of aliased and anti-aliased textures in your game, then you can change them on a per-texture basis by using `Texture.setFilter`.

There is a third game config property called `pixelArt`. If set to `true` it's the same thing as enabling `roundPixels` and disabling `antialias`. This is the optimum setting for pixel art games.

* Both renderers will now check for `pixelArt` OR `antialias` before setting the canvas scale mode. Both values are checked during texture creation as well.
* If in your game config you have enabled either pixel art mode or roundPixels, then all Cameras will have their `roundPixels` values set to `true` by default. You can toggle this by changing the `CameraManager.roundPixels` property, or change it on a camera-by-camera basis, as needed.
* `Camera.roundPixels` is now used across all rendering code for both Canvas and WebGL. Previously, it would check the renderer config value, but now all renderer code uses the camera value to decide if it should floor the drawing position or not.

### Texture Tint Pipeline - New Features, Updates and Fixes

The Texture Tint Pipeline has been rewritten to tidy up hundreds of lines of duplicate code and to move the responsibility of drawing to the Game Objects themselves. Previously, had you excluded say Tilemaps from your build of Phaser, the renderer would still include masses of code dealing with the drawing of them. Now, this task has been moved to the Game Objects and the pipeline just provides a set of clean utility functions for batching, flushing and drawing.

* You can now set the WebGL batch size in the Game Config via the property `batchSize`. The default is 2000 before the batch will flush, which is a happy average between desktop and mobile. If targeting desktop specifically, you may wish to increase this value to reduce draw calls.
* The `batchTileSprite` method has been removed from the `TextureTintPipeline` class, because it is now handled internally by the Game Object itself.
* The `drawStaticTilemapLayer` method has been removed from the `TextureTintPipeline` class, because it is now handled internally by the Game Object itself.
* The `batchText` method has been removed from the `TextureTintPipeline` class, because it is now handled internally by the Game Object itself.
* The `batchDynamicTilemapLayer` method has been removed from the `TextureTintPipeline` class, because it is now handled internally by the Game Object itself.
* The shader has a new attribute: `tintEffect`. This is a single FLOAT.
* The vertex size has increased by 1 FLOAT to account for the extra shader attribute.

Due to the changes in the Texture Tint Pipeline the `Textures.Frame` class has also been updated. The following changes concern the Frame UV data:

* Previously, the UV data spanned 8 properties: `x0`, `y0`, `x1`, `y1`, `x2`, `y2`, `x3` and `y3` and was stored in the `data.uvs` object. These have been replaced with directly accessible properties: `u0`, `v0`, `u1` and `v1`. These 4 properties are used directly in all renderer code now. Although it was clearer having 8 properties, 4 of them were just duplicates, so we've traded a little clarity for a smaller overall object and less dictionary look-ups.
* `Frame.uvs` (and the corresponding `Frame.data.uvs`) object has been removed.

### New Tint Effects

As well as tidying the Texture Tint Pipeline, I also updated the shader. It now has a new attribute 'tintEffect' which allows you to control how a tint is applied to a Game Object. The default way tinting worked was for the tint color values to be multiplied with the texture pixel values. This meant you were unable to do things like tint a Game Object white, because multiplying a color by white doesn't change it. The new tint mode allows you to literally replace the pixel color values.

* `setTintFill` is a new method available to all Game Objects that have the Tint component. It differs from `setTint` in that the colors literally replace the pixel values from the texture (while still respecting the alpha). This means you can now create effects such as flashing a sprite white if it gets hit, or red for damage, etc. You can still use different colors per corner of the Game Object, allowing you to create nice seamless gradient effects.
* `tintFill` is a new boolean property that allows you to toggle between the two different tint types: multiply or replace.
* `isTinted` is a new read-only boolean indicating if a Game Object is tinted or not. Handy for knowing if you need to clear a tint after an effect.

The Tint component documentation has been overhauled to explain these differences in more detail, and you can find lots of new examples as well.

### New Texture Crop Component

There is a new Game Object Component called `TextureCrop`. It replaces the Texture Component (which still exists) and adds in the ability to crop the texture being used. This component is now being used by the `Sprite` and `Image` Game Objects.

* You can crop the frame being used via the new `setCrop` method. The crop is a rectangle that limits the area of the texture frame that is visible during rendering. Cropping a Game Object does not change its size, dimensions, physics body or hit area, it just changes what is shown when rendered. This is ideal for hiding part of a Sprite without using a mask, or for effects like displaying a progress or loading bar. Cropping works even when the Game Object is flipped, or is a trimmed frame from an atlas.
* You can toggle the crop on a Game Object by changing the `isCropped` boolean at any point.
* The crop is automatically re-applied when the texture or frame of a Game Object is changed. If you wish to disable this, turn off the crop before changing the frame.

### New Features

* `Graphics.fillRoundedRect` will draw a stroked rounded rectangle to a Graphics object. The radius of the corners can be either a number, or an object, allowing you to specify different radius per corner (thanks @TadejZupancic)
* `Graphics.strokeRoundedRect` will draw a filled rounded rectangle to a Graphics object. The radius of the corners can be either a number, or an object, allowing you to specify different radius per corner (thanks @TadejZupancic)
* `ParticleEmitter.stop` is a new chainable method to stop a particle emitter. It's the same as setting `on` to `false` but means you don't have to break the method flow to do so (thanks @samme)
* `ScenePlugin.pause` (and the corresponding methods in Scene Systems and the Scene Manager) now has a new optional `data` argument, which is passed to the target Scene and emitted in its 'pause' event.
* `ScenePlugin.resume` (and the corresponding methods in Scene Systems and the Scene Manager) now has a new optional `data` argument, which is passed to the target Scene and emitted in its 'resume' event.
* `ScenePlugin.sleep` (and the corresponding methods in Scene Systems and the Scene Manager) now has a new optional `data` argument, which is passed to the target Scene and emitted in its 'sleep' event.
* `ScenePlugin.wake` (and the corresponding methods in Scene Systems and the Scene Manager) now has a new optional `data` argument, which is passed to the target Scene and emitted in its 'wake' event.
* `ScenePlugin.setActive` now has a new optional `data` argument, which is passed to the target Scene and emitted in its 'pause' or 'resume' events.
* `TileSprite.tileScaleX` and `tileScaleY` are two new properties that allow you to control the scale of the texture within the Tile Sprite. This impacts the way the repeating texture is scaled, and is independent to scaling the Tile Sprite itself. It works in both Canvas and WebGL mode.
* `TransformMatrix.copyFrom` is a new method that will copy the given matrix into the values of the current one.
* `TransformMatrix.multiplyWithOffset` is a new method that will multiply the given matrix with the current one, factoring in an additional offset to the results. This is used internally by the renderer code in various places.
* `Rectangle.Intersection` will take two Rectangle objects and return the area of intersection between them. If there is no intersection, an empty Rectangle is returned.

### Updates

* DataManager.removeValue (and by extension the `remove` method too) will not emit the parent of the DataManager as the 2nd argument in the `removedata` event, to keep it consistent with the set events (thanks @rexrainbow)
* The docs for the Loader `filecomplete` event said that you could listen for a specific file using its type and key, i.e.: `filecomplete-image-monster`, however, the code used an underscore instead of a hyphen. We feel the hyphen looks cleaner, so the Loader code has been updated, meaning you can now use the hyphen version of the event properly (thanks @NokFrt)
* If a Game Object is already being dragged, it cannot be dragged by another pointer (in multi-touch mode) until the original pointer has released it (thanks @rexrainbow)
* Calling `Tween.play` on a tween created via `TweenManager.create` wouldn't actually start playback until the tween was first added to the Tween Manager. Now, calling `play` will have it automatically add itself to the Tween Manager if it's not already in there. Fix #3763 (thanks @pantoninho)
* If the Blitter object has no Bob's to render it will now abort immediately, avoiding several context calls in Canvas mode.
* `Scene.run` will now pass the optional `data` object in all cases, no matter if it's waking, resuming or starting a Scene (thanks @rook2pawn)
* `ScenePlugin.start` and `ScenePlugin.restart` will now always queue the op with the Scene Manager, regardless of the state of the Scene, in order to avoid issues where plugins carry on running for a frame before closing down. Fix #3776 (thanks @jjalonso)
* `Tileset.glTexture` is a new property that maps to the WebGL Texture for the Tileset image. It's used internally by the renderer to avoid expensive object look-ups and is set automatically in the `Tileset.setImage` method.
* `Frame.glTexture` is a new property that maps to the WebGL Texture for the Frames Texture Source image. It's used internally by the renderer to avoid expensive object look-ups and is set automatically in the `Frame` constructor.
* `TransformMatrix.e` and `TransformMatrix.f` are two new properties that are an alias for the `tx` and `ty` values.
* `Graphics.arc` has a new optional argument `overshoot`. This is a small value that is added onto the end of the `endAngle` and allows you to extend the arc further than the default 360 degrees. You may wish to do this if you're trying to draw an arc with an especially thick line stroke, to ensure there are no gaps. Fix #3798 (thanks @jjalonso)

### Bug Fixes

* The DataManager `changedata` event was emitting the original value of the data instead of new value (thanks @iamchristopher) 
* The LoaderPlugin didn't emit the `filecomplete` event if any of files failed to load, causing it to fail to run the Scene `create` function as well. Fix #3750 (thanks @NokFrt)
* Fix setter calls in BuildGameObjectAnimation so it will now properly set the delay, repeat, repeat delay and yoyo of a config based animation (thanks @DannyT)
* The Arcade Body `blocked.none` property is now set to `false` after separation with static bodies or tiles. Previously, the blocked direction was set correctly, but the `none` remained `true` (thanks @samme)
* `Bob.setFrame` didn't actually set the frame on the Bob, now it does. Fix #3774 (thanks @NokFrt)
* `Bob.alpha` was ignored by the canvas renderer, only working in WebGL. This has now been fixed.
* Although the Blitter object had the Alpha component, setting it made no difference. Setting Blitter alpha now impacts the rendering of all children, in both Canvas and WebGL, and you can also specify an alpha per Bob as well.
* `SceneManager.run` would ignore scenes that are currently in the queue of scenes pending to be added. This has now been fixed so that the scene is queued to be started once it's ready (thanks @rook2pawn)
* `GameObject.disableInteractive` was toggling input. Every second call would turn the input back on (thanks @TadejZupancic)
* The position of the TilemapLayer wasn't taken into account when culling tiles for the Camera. It's now calculated as part of the cull flow (thanks @Upperfoot)
* Fix extra argument passing in Array.Each (thanks @samme)
* TileSprite was using the Size component instead of ComputedSize, meaning its `getBounds` and `displayWidth` and `displayHeight` results were incorrect. Fix #3789 (thanks @jjalonso)
* `ArrayUtils.AddAt` didn't calculate the array offset correctly if you passed an array in to be merged with an existing array. This also caused Container.addAt to fail if an array was passed to it. Fix #3788 (thanks @jjalonso)
* The `Pointer.camera` property would only be set if there was a viable Game Object in the camera view. Now it is set regardless, to always be the Camera the Pointer interacted with.
* Added the Mask component to Container. It worked without it, but this brings it in-line with the documentation and other Game Objects. Fix #3797 (thanks @zilbuz)
* The DataManager couldn't redefine previously removed properties. Fix #3803 (thanks @AleBles @oo7ph)
* The Canvas DrawImage function has been recoded entirely so it now correctly supports parent matrix and camera matrix calculations. This fixes an issue where children inside Containers would lose their rotation, and other issues, when in the Canvas Renderer. Fix #3728 (thanks @samid737)
* `clearMask(true)` would throw an exception if the Game Object didn't have a mask. Now it checks first before destroying the mask. Fix #3809 (thanks @NokFrt)

## Version 3.10.1 - Hayashi - 13th June 2018

### Bug Fixes

* The InputManager would only create 1 Pointer, even if Touch input was enabled in the config, which meant you couldn't use touch events unless you first called `addPointer` or specified one in the config. Now, it Touch is enabled in the config, it'll always create 2 pointers by default.

## Version 3.10.0 - Hayashi - 13th June 2018

### Input System New Features + Updates

* All Input classes are now covered 100% by JSDocs.
* The Input Manager and Input Plugin have been updated to support multiple simultaneous Pointers. Before, only one active pointer (mouse or touch) was supported. Now, you can have as many active pointers as you need, allowing for complex multi-touch games. These are stored in the Input Manager `pointers` array.
* `addPointer` allows you to add one, or more, new pointers to the Input Manager. There is no hard-coded limit to the amount you can have, although realistically you should never need more than 10. This method is available on both the Input Manager and Plugin, allowing you to use `this.input.addPointer` from within your game code.
* InputManager `pointersTotal` contains the total number of active pointers, which can be set in the Game Config using the `input.activePointers` property. Phaser will create 2 pointers on start unless a different value is given in the config, or you can add them at run-time.
* `mousePointer` is a new property that is specifically allocated for mouse use only. This is perfect for desktop only games but should be ignored if you're creating a mouse + touch game (use activePointer instead).
* `activePointer` will now reflect the most recently active pointer on the game, which is considered as being the pointer to have interacted with the game canvas most recently.
* The InputManager and InputPlugin have three new methods: `addUpCallback`, `addDownCallback` and `addMoveCallback`. These methods allow you to add callbacks to be invoked whenever native DOM mouse or touch events are received. Callbacks passed to this method are invoked _immediately_ when the DOM event happens, within the scope of the DOM event handler. Therefore, they are considered as 'native' from the perspective of the browser. This means they can be used for tasks such as opening new browser windows, or anything which explicitly requires user input to activate. However, as a result of this, they come with their own risks, and as such should not be used for general game input, but instead be reserved for special circumstances. The callbacks can be set as `isOnce` so you can control if the callback is called once then removed, or every time the DOM event occurs.
* Pointer has two new properties `worldX` and `worldY` which contain the  position of the Pointer, translated into the coordinate space of the most recent Camera it interacted with.
* When checking to see if a Pointer has interacted with any objects it will now iterate through the Camera list. Previously, it would only check against the top-most Camera in the list, but now if the top-most camera doesn't return anything, it will move to the next camera and so on. This also addresses #3631 (thanks @samid737)
* `InputManager.dirty` is a new internal property that reflects if any of the Pointers have updated this frame.
* `InputManager.update` now uses constants internally for the event type checking, rather than string-based like before.
* `InputManager.startPointer` is a new internal method, called automatically by the update loop, that handles touch start events.
* `InputManager.updatePointer` is a new internal method, called automatically by the update loop, that handles touch move events.
* `InputManager.stopPointer` is a new internal method, called automatically by the update loop, that handles touch end events.
* `InputManager.hitTest` has had its arguments changed. It no longer takes x/y properties as the first two arguments, but instead takes a Pointer object (from which the x/y coordinates are extracted).
* `TouchManager.handler` has been removed as it's no longer used internally.
* `TouchManager.onTouchStart`, `onTouchMove` and `onTouchEnd` are the new DOM Touch Event handlers. They pass the events on to the InputManagers `queueTouchStart`, `queueTouchMove` and `queueTouchEnd` methods respectively.
* `MouseManager.handler` has been removed as it's no longer used internally.
* `MouseManager.onMouseDown`, `onMouseMove` and `onMouseUp` are the new DOM Mouse Event handlers. They pass the events on to the InputManagers `queueMouseDown`, `queueMouseMove` and `queueMouseUp` methods respectively.
* Setting `enabled` to false on either the TouchManager, MouseManager or KeyboardManager will prevent it from handling any native DOM events until you set it back again.
* InputPlugin has the following new read-only properties: `mousePointer`, `pointer1`, `pointer2`, `pointer3`, `pointer4`, `pointer5`, `pointer6`, `pointer7`, `pointer8`, `pointer9` and `pointer10`. Most of these will be undefined unless you call `addPointer` first, or set the active pointers quantity in your Game Config.
* InputManager has a new method `transformPointer` which will set the transformed x and y properties of a Pointer in one call, rather than the 2 calls it took before. This is now used by all Pointer event handlers.
* InputPlugin has a new method `makePixelPerfect` which allows you to specify a texture-based Game Object as being pixel perfect when performing all input checks against it. You use it like this: `this.add.sprite(x, y, key).setInteractive(this.input.makePixelPerfect())`, or the easier: `setInteractive({ pixelPerfect: true })` - you can also pass or set an optional alpha tolerance level. See the method docs for full details and the new examples to see it in action. Note that as a pointer interacts with the Game Object it will constantly poll the texture, extracting a single pixel from the given coordinates and checking its color values. This is an expensive process, so should only be enabled on Game Objects that really need it.

### Input - Custom Cursors

* You can now set a custom cursor for your game via `this.input.setDefaultCursor()`. This will take any valid CSS cursor string, including URLs to cursor image files.
* You can now set a custom cursor for specific Game Objects. This will take any valid CSS cursor string, including URLs to cursor image files, and is used when-ever a pointer is over that Game Object. For example, to have a hand cursor appear when over a button Sprite, you can do: `button.input.cursor = 'pointer'`, or to have a help cursor appear: `button.input.cursor = 'help'`, or to have a custom image: `button.input.cursor = 'url(assets/cursors/sword.cur), pointer'`.
* You can also set a custom cursor in the new Input Configuration Object. To use the `pointer` (hand cursor) there is a new short-cut: `setInteractive({ useHandCursor: true })`. To use anything else: `setInteractive({ cursor: CSSString })` where `CSSString` is any valid CSS for setting a cursor.
* Please be aware of limitations when it comes to image based cursors between browsers. It's up to you to find a suitable format and size that fits the browsers you wish to support (note: virtually all modern browsers no longer support animated CSS cursors.)

### Input - Configuration Objects

* The `setInteractive` method can now take an Input Configuration object as its only argument. This allows you to set multiple input related properties in a single call, i.e.: `setInteractive({ draggable: true, pixelPerfect: true })`. The available properties are:
* `hitArea` - The object / shape to use as the Hit Area. If not given it will try to create a Rectangle based on the texture frame.
* `hitAreaCallback` - The callback that determines if the pointer is within the Hit Area shape or not.
* `draggable` - If `true` the Interactive Object will be set to be draggable and emit drag events.
* `dropZone` - If `true` the Interactive Object will be set to be a drop zone for draggable objects.
* `useHandCursor` - If `true` the Interactive Object will set the `pointer` hand cursor when a pointer is over it. This is a short-cut for setting `cursor: 'pointer'`.
* `cursor` - The CSS string to be used when the cursor is over this Interactive Object.
* `pixelPerfect` - If `true` the a pixel perfect function will be set for the hit area callback. Only works with texture based Game Objects.
* `alphaTolerance` - If `pixelPerfect` is set, this is the alpha tolerance threshold value used in the callback.

### Input - Keyboard Manager Updates

* The `KeyboardManager` class has been removed. It has been replaced with `KeyboardPlugin` which is now an Input level plugin, that registers itself with the new `InputPluginCache`. The Input Plugin class (which belongs to a Scene) will now automatically inject registered plugins into itself on boot. Every Scene has its own instance of the Input Plugin (if enabled in the scene plugins), which in turn has its own instance of the KeyboardPlugin. The `InputManager` no longer has any reference to the Keyboard class at all. The benefits of this are two-fold: First, it allows you to now entirely exclude all of the keyboard classes from a custom build, saving a lot of space if not required. Secondly, it means that the Scenes themselves are now responsible for keyboard events, where-as before they were entirely global. This means a Scene can be paused and stop processing keyboard events, and stop having its Key objects updated, while another Scene can still carry on doing this. It also prevents key related callbacks in sleeping Scenes from being fired (which resolves issue #3733, thanks @JoeMoov2)
* `KeyboardManager.handler` has been renamed to `onKeyHandler`.
* The `KeyboardManager.captures` property has been removed as it can be more effectively handled by polling the `keys` object instead.
* The Keyboard Manager will no longer process key down or up events if its `enabled` property is set to false, or if the Scene to which it belongs is not active.
* The Keyboard Manager will now call `event.preventDefault` on the native DOM event as long as the Key exists in the keys array and has its `preventDefault` property set to `true` (which is the default). This means you can now control specifically which key prevents default on the browser, where-as before every key added did so.
* KeyboardManager `addKeyCapture` and `removeKeyCapture` have been removed as you now control which keys prevent capture by using the `addKey` or `addKeys` methods (see entry above). The act of creating a Key is now enough to enable capture of it and can be toggled (at run-time) on a per-Key basis.
* `KeyboardManager.addKeys` can now take either an object, or key codes, or a comma-separated string as its input. This means you can now do: `keyboard.addKeys('W,S,A,D')` and get an object back with the properties WSAD mapped to the relevant Key objects.
* `KeyboardManager.addKey` can now take either a Key object, a string, such as `A` or `SPACE`, or a key code value.
* `KeyboardManager.removeKey` can now take either a Key object, a string, such as `A` or `SPACE`, or a key code value.

### Input - Gamepad Manager Updates

* The `GamepadManager` class has been removed. It has been replaced with `GamepadPlugin` which is now an Input level plugin, that registers itself with the new `InputPluginCache`. The Input Plugin class (which belongs to a Scene) will now automatically inject the registered plugins into itself on boot. Every Scene has its own instance of the Input Plugin (if enabled in the scene plugins), which in turn has its own instance of the GamepadPlugin. The `InputManager` no longer has any reference to the Gamepad class at all. The benefits of this are two-fold: First, it allows you to now entirely exclude all of the gamepad classes from a custom build, saving a lot of space if not required. Secondly, it means that the Scenes themselves are now responsible for gamepad events, where-as before they were entirely global. This means a Scene can be paused and stop processing gamepad events, and stop having its Gamepad objects updated, while another Scene can still carry on doing this. It also prevents gamepad related callbacks in sleeping Scenes from being fired.
* The Gamepad Plugin has been rewritten from scratch. It now offers a lot more features and far easier access to the Gamepads and their properties. You can now access the first 4 gamepads connected to the browser via the `pad1` to `pad4` properties, meaning you can do: `this.input.gamepad.pad1` for direct access to a pad once it's connected.
* The Gamepad class has also been rewritten from scratch. It will no longer create Buttons or Axes dynamically, instead doing so on instantiation.
* The Gamepad class now has a bunch of new properties for easy access to the various standard mapping buttons. These include `left`, `right`, `up`, `down` for directions, `A`, `Y`, `X` and `B` for buttons, `L1`, `L2`, `R1` and `R2` for shoulder buttons, and `leftStick` and `rightStick` for the axis sticks. You can still use `Gamepad.getButtonValue()` to get the value from a button and `Gamepad.getButtonTotal()` to get the total number of buttons available on the pad.
* `Gamepad.getAxisTotal` and `Gamepad.getAxisValue` will return the total number of axis, and an axis value, accordingly.
* `Gamepad.setAxisThreshold` will now let you set the threshold across all axis of a Gamepad in one call.
* The Gamepad `Button` objects will now emit 2 events, one from the button itself and another from the Gamepad. This means you can listen for button events in 3 ways: 1) By directly polling the button value in an update loop, 2) Listening for events on the Gamepad Plugin: `this.input.gamepad.on('down')`, or 3) By listening for events on the Gamepad itself: `gamepadReference.on('down')`.

### Arcade Physics New Features + Updates

* Arcade Physics now uses a fixed time-step for all internal calculations. There is a new `fps` config value and property (defaults to 60fps), which you can change at run-time using the `setFPS` method. The core update loop has been recoded so that it steps based entirely on the given frame rate, and not the wall-clock or game step delta. This fixed time step allows for a straightforward implementation of a deterministic game state. Meaning you can now set the fps rate to a high value such as 240, regardless of the browser update speed (it will simply perform more physics steps per game step). This is handy if you want to increase the accuracy of the simulation in certain cases.
* You can also optionally call the `step` function directly, to manually advance the simulation.
* There is a new property `timeScale` which will scale all time-step calculations at run-time, allowing you to speed-up or slow-down your simulation at will, without adjusting the frame rate.
* You can now disable the use of the RTree for dynamic bodies via the config property `useTree`. In certain situations, i.e. densely packed worlds, this may give better performance. Static bodies will always use an RTree.
* `collideSpriteVsGroup` has been rewritten. If you are using an RTree it now uses the results directly from the tree search, instead of iterating all children in the Group, which dramatically reduces the work it does. If you have disabled the RTree it performs a brute-force O(N2) Sprite vs. Group iteration sweep. We tested multiple axis sorting variants but the cost of the array allocation and/or sorting, with large amounts of bodies (10,000+), far outweighed the simple math involved in the separation logic.
* `Body.useDamping` is a new boolean property that allows you to use a damping effect for drag, rather than the default linear deceleration. This gives much better results if you need smooth deceleration across both axis, such as the way the ship slows down in the game Asteroids, without the tell-tale axis drift associated with linear drag.
* `GetOverlapX` and `GetOverlapY` now use the calculated delta values, not the deltaX/Y methods.
* `collideSpriteVsGroup` aborts early if the Sprite body has been disabled.
* `updateMotion` has a new argument `delta` which should typically be a fixed-time delta value.
* `intersects` has been restructured to prioritize rect vs. rect checks.
* Body `update` and `postUpdate` have been recoded to handle the new fixed time-step system in place. `update` now takes a new argument, delta, which is used internally for calculations.
* `Body.dirty` has been removed as a property as it's no longer used internally.
* `Body.deltaAbsX` and `deltaAbsY` now return the cached absolute delta value from the previous update, and no longer calculate it during the actual call.
* `World.enable` has been recoded to remove all the `hasOwnProperty` checks and streamline the internal flow.
* `World.disable` has been recoded to remove all the `hasOwnProperty` checks and streamline the internal flow.
* `World.add` is a new method that adds an existing body to the simulation and `enableBody` now passes its newly created bodies to this method.
* `World.disableGameObjectBody` has been removed as it duplicated what the `disable` method did.
* There is a new internal flow with regard to the creation and disabling of bodies. Calling `World.enable` will pass the objects to `enableBody`, which will create a new Body object, if required, and finally pass it to `add`. `World.disable` does the same, but removes the bodies from the simulation. It passes the bodies to `disableBody`, which in turn passes it to `remove`. Both of these work for single objects, an array of objects, Groups or even arrays of Groups.
* `World.computeAngularVelocity` is a new method that specifically calculates the angular velocity of a Body.
* `World.computeVelocity` has had its signature changed. Rather than taking a bunch of arguments all it now takes is a Body and a delta value. Internally it now calculates both the x and y velocity components together in the same single call, where-as before it was split into two calls and multiple assignments.
* `World.computeVelocity` no longer returns the new velocities, they are now set directly on the body within the method.
* `World.computeVelocity` has been recoded to use Fuzzy Greater Than and Less Than calls when applying drag to a previously accelerated body. Using a fuzzy epsilon allows us to mitigate the ping-pong issue, where a decelerating body would constantly flip between a small negative and positive velocity value and never come to an actual rest.
* `World.computeVelocity` now checks the `Body.useDamping` property to perform either linear deceleration or damping on the Body.
* `World.updateMotion` has changed to call the new `computeAngularVelocity` and `computeVelocity` methods.
* Bodies set to bounce would eventually run out of velocity and stop. This has been fixed as part of the refactoring of the time step and compute velocity updates. Fix #3593 (thanks @helmi77)
* If a Body collides with a Static Body it will now set the `blocked` properties accordingly (before it only set the `touching` properties.) This means you can now use checks like `Body.onFloor()` when traversing static bodies (thanks @fariazz)

### Data Manager New Features and Updates

* You can now access anything set in the DataManager using the new `values` property. For example, if you set a new value such as this: `data.set('gold', 50)` you can now access it via: `data.values.gold`, where it is treated as a normal property, allowing you to use it in conditional evaluations `if (data.values.level === 2)`, or modify it: `data.values.gold += 50`.
* Each time a value is updated it emits a `changedata` event, regardless if it is changed via the `set` method, or the new `values` approach.
* Each time a value is updated it emits a new event named after the value. For example, if the value was called `PlayerLives`, it will emit the event `changedata_PlayerLives`. This happens regardless if it is changed via the `set` method, or the new `values` approach.
* The `set` method can now take an object containing key value pairs as the first argument. This means you can now set a bunch of values all at once, i.e: `data.set({ name: 'Red Gem Stone', level: 2, owner: 'Link', gold: 50 })`.
* The `get` method can now take an array of keys, and will return an array of matching values. This is handy for array destructuring in ES6.
* The `remove` method can now take an array of keys, and will remove all matching values, emitting the `removedata` event for each.
* The order of events has been updated. When a value is first set, and doesn't already exist in the Data Manager, it will emit a `setdata` event. If a value is set that already exists, it instead emits a `changedata` and related `changedata_key` event. Setting a new value no longer emits both events.
* The `resetFunction` function has been removed from the `changedata` event arguments. Previously this was used to allow you to stop a value being updated by calling the reset function instead. However, it created brand new anonymous functions every single time a value was updated. As you can now access stored data via the `values` property you can use this for much easier conditional checks and sets.
* The `blockSet` property has been removed as it's no longer used internally.

### Loader and Scene Updates

* Internally, the Loader has changed slightly. Rather than have each file cause the new batch to load, an `update` method is polled every frame, which does the same job instead. This avoids load-time race conditions where pre-populated files would trigger loads part way during an existing load, fixing #3705 in the process (thanks @the-simian)
* The Scene Manager has been updated so that it will call Scene.Systems.step during the `init`, `preload` and `create` phase of your Scene. This means that any plugins, or custom code, written to use the Scene Systems `preupdate`, `update` or `postupdate` events will need to be aware that these are now fired from `init` onwards, not just once `create` has finished.
* As a result of these two changes, there is a new Systems property called `sceneUpdate`, which is a reference that maps to your `Scene.update` function. During `init`, `preload` and `create` this is always mapped to NOOP. Once `create` has finished it gets re-mapped to your Scene's update function. If your Scene doesn't have one, it remains mapped to NOOP. In practise, this means nothing has changed from before. `Scene.update` never ran until `create` was completed, and it still doesn't. However, because the internal Scene systems are now updating right from `init`, it means that things like the update list and physics systems are fully operational _during_ your Preloader. This allows you to create far more elaborate preloaders than ever before. Although, with great power comes great responsibility, as the onus is now on you to be careful which events you consume (especially input events) during your preloader.
* Another side-effect of these changes is that Scenes no longer need an 'update' function at all. Previously, if they were missing one, the Scene Manager would inject one into them automatically. It no longer does this.

### New Features

* `RenderTexture.resize` will allow you to resize the underlying Render Texture to the new dimensions given. Doing this also clears the Render Texture at the same time (thanks @saqsun).
* `Rectangle.RandomOutside` is a new function that takes two Rectangles, `outer` and `inner`, and returns a random point that falls within the outer rectangle but is always outside of the inner rectangle.
* The Update List has a new read-only property `length`, making it consistent with the Display List (thanks @samme)
* The 2D Camera class has two new read-only properties `centerX` and `centerY` which return the coordinates of the center of the viewport, relative to the canvas (thanks @samme)
* Camera has a new property `visible`. An invisible Camera will skip rendering and input tests of everything it can see. This allows you to create say a mini-cam and then toggle it on and off without needing to re-create it each time.
* Camera has a new method `setVisible` which toggles its visible property.
* `CameraManager.fromJSON` will now set the visible property is defined in the config.
* `ScenePlugin.run` is a new method that will run the given Scene and not change the state of the current Scene at all. If the scene is asleep, it will be woken. If it's paused, it will be resumed. If not running at all, it will be started.
* `TextureManager.getPixelAlpha` is a new method that will return the alpha value of a pixel from the given texture and frame. It will return `null` if the coordinates were out of bounds, otherwise a value between 0 and 255.
* `Game.isOver` is a new read-only boolean property that indicates if the mouse pointer is currently over the game canvas or not. It is set by the VisibilityHandler and is only reliable on desktop systems.
* A new event `Game.mouseout` is dispatched if the mouse leaves the game canvas. You can listen to it from `this.sys.game.events.on('mouseout')` from within a Scene.
* A new event `Game.mouseover` is dispatched if the mouse enters the game canvas, having previously been outside of it. You can listen to it from `this.sys.game.events.on('mouseover')` from within a Scene.
* You can now use PhysicsEditor (https://www.codeandweb.com/physicseditor) to create complex Matter.js bodies. Load them as normal JSON and then just pass it to the Matter Sprite as a shape property: `this.matter.add.sprite(x, y, texture, frame, { shape: shapes.banana })` (where `shapes.banana` is one of the exported PhysicsEditor shapes in the JSON you loaded). See the 'physics/matterjs/advanced shape creation.js' example for more details.

### Updates

* The `ForwardDiffuseLightPipeline`, used by the Lights system, now sets a flag if the Scene doesn't contain any lights. All of the Game Objects now check this flag and don't even bother adding themselves to the batch if there are no lights in the Scene, as they'd never render anyway. This also avoids the ghost-image problem if you swap Scenes to a new Scene with the Light Manager enabled, but no actual lights defined. Fix #3707 (thanks @samvieten).
* `CameraManager.getCameraBelowPointer` has been renamed to `getCamerasBelowPointer` and it now returns an array of all the cameras below the given pointer, not just the top-most one. The array is sorted so that the top-most camera is at the start of the array.
* In `TimeStep.step` the `rawDelta` and `delta` values are checked to make sure they are non-negative, which can happen in Chrome when the delta is reset and out of sync with the value passed to Request Animation Frame. Fix #3088 (thanks @Antriel)
* `Cameras.Controls.Fixed` has been removed. It's was deprecated a few versions ago. Please use `FixedKeyControl` instead.
* `Cameras.Controls.Smoothed` has been removed. It's was deprecated a few versions ago. Please use `SmoothedKeyControl` instead.

### Bug Fixes

* The Canvas `RenderTexture.drawImage` method incorrectly set the values of the frame, causing them to appear wrongly scaled in the canvas renderer. Fix #3710 (thanks @saqsun).
* Fixed `Math.Matrix4.makeRotationAxis()` (thanks @hexus)
* Fixed an incorrect usage of `Math.abs()` in `Math.Quaternion.calculateW()` (thanks @qxzkjp).
* Particle Emitter Managers can now be added to Containers (thanks @TadejZupancic)
* Fixed a method signature issue with the Animation component's `remove()` handler when `Animation`s are removed from the `AnimationManager`. This prevented removed animations from stopping correctly.
* If you set Phaser to use a pre-existing Canvas element it is no longer re-added to the DOM (thanks @NQNStudios)
* The `TweenManager.getTweensOf` method has been fixed to remove a potential endless loop should multiple targets be passed in to it (thanks @cyantree)
* Interactive Objects inside of Containers would still fire their input events even if the Container (or any ancestor) was set to be invisible. Objects now check their ancestor tree during the input cull and now properly skip input events if not visible. Fix #3620 (thanks @NemoStein)
* Fixed Device.os incorrectly reporting Linux as OS on Android devices (thanks @AleBles)

### Examples, Documentation and TypeScript

Thanks to the work of @hexus we have now documented all of the Math namespace and made good progress on the Game Objects.

I personally have also documented the entire Input system, which was 328 classes, properties and methods to describe, as well as lots of other areas.

## Version 3.9.0 - Yui - 24th May 2018

### New Features

* The command `npm run help` will display a friendly list of all the scripts available (run `npm install` first)
* Game has a new property `hasFocus` which is a read-only boolean that lets you know if the window the game is embedded in (including in an iframe) currently has focus or not.
* Game.Config has a new property `autoFocus`, which is `true` by default, and will automatically call `window.focus()` when the game starts.
* Clicking on the canvas will automatically call `window.focus`. This means in games that use keyboard controls if you tab or click away from the game, then click back on it again, the keys will carry on working (where-as before they would remain unfocused)
* Arcade Physics Body has a new method `setAllowDrag` which toggles the `allowDrag` property (thanks @samme)
* Arcade Physics Body has a new method `setAllowGravity` which toggles the `allowGravity` property (thanks @samme)
* Arcade Physics Body has a new method `setAllowRotation` which toggles the `allowRotation` property (thanks @samme)
* Arcade Physics Group Config has 3 new properties you can use: `allowDrag`, `allowGravity` and `allowRotation` (thanks @samme)
* PluginManager.registerFileType has a new property `addToScene` which allows you to inject the new file type into the LoaderPlugin of the given Scene. You could use this to add the file type into the Scene in which it was loaded.
* PluginManager.install has a new property `mapping`. This allows you to give a Global Plugin a property key, so that it is automatically injected into any Scenes as a Scene level instance. This allows you to have a single global plugin running in the PluginManager, that is injected into every Scene automatically.
* Camera.lerp has been implemented and allows you to specify the linear interpolation value used when following a target, to provide for smoothed camera tracking.
* Camera.setLerp is a chainable method to set the Camera.lerp property.
* Camera.followOffset is a new property that allows you to specify an offset from the target position that the camera is following (thanks @hermbit)
* Camera.setFollowOffset is a chainable method to set the Camera.followOffset property.
* Camera.startFollow has 4 new arguments: `lerpX` and `lerpY` which allow you to set the interpolation value used when following the target. The default is 1 (no interpolation) and `offsetX` and `offsetY` which allow you to set the follow offset values.
* Camera.startFollow will now immediately set the camera `scrollX` and `scrollY` values to be that of the target position to avoid a large initial lerps during the first few preUpdates.
* Math.Interpolation.SmoothStep is a new method that will return the smooth step interpolated value based on the given percentage and left and right edges.
* Math.Interpolation.SmootherStep is a new method that will return the smoother step interpolated value based on the given percentage and left and right edges.

### Updates

* Container.setInteractive can now be called without any arguments as long as you have called Container.setSize first (thanks rex)
* Bob.reset will now reset the position, frame, flip, visible and alpha values of the Bob.
* VisibilityHandler now takes a game instance as its sole argument, instead of an event emitter.
* PluginManager.createEntry is a new private method to create a plugin entry and return it. This avoids code duplication in several other methods, which now use this instead.
* The Plugin File Type has a new optional argument `mapping`, which allows a global plugin to be injected into a Scene as a reference.
* TileSprite.destroy has been renamed to `preDestroy` to take advantage of the preDestroy callback system.
* RenderTexture.destroy has been renamed to `preDestroy` to take advantage of the preDestroy callback system.
* Group.destroy now respects the `ignoreDestroy` property.
* Graphics.preDestroy now clears the command buffer array.
* Container addHandler will now remove a child's Scene shutdown listener and only listens to `destroy` once.
* Container removeHandler will re-instate a child's Scene shutdown listener.
* Container preDestroy now handles the pre-destroy calls, such as clearing the container.
* Blitter preDestroy will now clear the children List and renderList.
* The AudioContextMonkeyPatch has been updated to use an iife. Fix #3437 (thanks @NebSehemvi)

### Bug Fixes

* PluginManager.destroy didn't reference the plugin correctly, throwing an Uncaught TypeError if you tried to destroy a game instance. Fix #3668 (thanks @Telokis)
* If a Container and its child were both input enabled they will now be sorted correctly in the InputPlugin (thanks rex)
* Fix TypeError when colliding a Group as the only argument in Arcade Physics. Fix #3665 (thanks @samme)
* The Particle tint value was incorrectly calculated, causing the color channels to be inversed. Fix #3643 (thanks @rgk)
* All Game Objects that were in Containers were being destroyed twice when a Scene was shutdown. Although not required it still worked in most cases, except with TileSprites. TileSprites specifically have been hardened against this now but all Game Objects inside Containers now have a different event flow, stopping them from being destroyed twice (thanks @laptou @PaNaVTEC)
* Camera.cull will now accurately return only the Game Objects in the camera view, instead of them all. Fix #3646 (thanks @KingCosmic @Yora)
* The `dragend` event would be broadcast even if the drag distance or drag time thresholds were not met. Fix #3686 (thanks @RollinSafary)
* Restarting a Tween immediately after creating it, without it having first started, would cause it to get stuck permanently in the Tween Managers add queue (thanks @Antriel @zacharysarette)
* Setting an existing Game Object as a static Arcade Physics body would sometimes incorrectly pick-up the dimensions of the object, such as with TileSprites. Fix #3690 (thanks @fariazz)
* Interactive Objects were not fully removed from the Input Plugin when cleared, causing the internal list array to grow. Fix #3645 (thanks @tjb295 for the fix and @rexrainbow for the issue)
* Camera.shake would not effect dynamic tilemap layers. Fix #3669 (thanks @kainage)

### Examples, Documentation and TypeScript

## Version 3.8.0 - Klein - 16th May 2018

### New Plugin Manager

New in this release is a revamped Plugin Manager. Phaser has always used plugins extensively internally but this release opens them up and builds in a lot of new features making them easy for you to both create and digest.

There is a new `Phaser.Plugins` namespace in which the classes live. The functions of the old PluginManager have moved to the new PluginCache and the PluginManager, which is available under `this.plugins` from all Scenes by default, now allows you to install and access any plugin.

Plugins are split into two different types: A Global Plugin and a Scene Plugin.

A **Global Plugin** is a plugin that lives within the Plugin Manager rather than a Scene. You can get access to it by calling `PluginManager.get` and providing a key. Any Scenes that request a plugin in this way all get access to the same plugin instance, allowing you to use a single plugin across multiple Scenes.

A **Scene Plugin** is a plugin dedicated to running within a Scene. These are different to Global Plugins in that their instances do not live within the Plugin Manager, but within the Scene Systems class instead. And that every Scene created is given its own unique instance of a Scene Plugin. Examples of core Scene Plugins include the Input Plugin, the Tween Plugin and the physics Plugins.

Plugins can now be installed in 3 different ways: 1) You can preload them, using the `load.plugin` and the new `load.scenePlugin` methods. This will allow you to load externally hosted plugins into your game, or pull down a plugin dynamically at run-time. 2) You can install global and scene plugins in your Game Configuration. The plugin code can be bundled with your game code into a single bundle. By specifying plugins in the game config they're instantly available as soon as your game boots. Finally, you can install plugins at run-time directly from within a Scene.

Plugins can also create brand new Game Objects and File Types, which install themselves into the respective factories. This means you can now write a plugin that adds a new file type and Game Object in a single package.

The new Plugin Manager and associated classes are 100% covered by JSDocs and there are stacks of new examples in the `plugins` folder in the Phaser 3 Labs too, so please dig in and have a play with these powerful new things!

### New Features

* You can pass in your own `canvas` and `context` elements in your Game Config and Phaser will use those to render with instead of creating its own. This also allows you to pass in a WebGL 2 context. Fix #3653 (thanks @tgrajewski)
* WebGLRenderer.config has a new property `maxTextures` which is derived from `gl.MAX_TEXTURE_IMAGE_UNITS`, you can get it via the new method `getMaxTextures()`.
* WebGLRenderer.config has a new property `maxTextureSize` which is derived from `gl.MAX_TEXTURE_SIZE`, you can get it via the new method `getMaxTextureSize()`
* WebGLRenderer has a new property `compression` which holds the browser / devices compressed texture support gl extensions, which is populated during `init`.
* When calling `generateFrameNames` to define an animation from a texture atlas you can now leave out all of the config properties and it will create an animation using every frame found in the atlas. Please understand you've no control over the sequence of these frames if you do this and it's entirely dictated by the json data (thanks @Aram19)
* The keycodes for 0 to 9 on the numeric keypad have been added. You can now use them in events, i.e. `this.input.keyboard.on('keydown_NUMPAD_ZERO')` (thanks @Gaushao)
* All Game Objects have a new method `setRandomPosition` which will randomly position them anywhere within the defined area, or if no area is given, anywhere within the game size.

### Updates

* Game.step now emits a `prestep` event, which some of the global systems hook in to, like Sound and Input. You can use it to perform pre-step tasks, ideally from plugins.
* Game.step now emits a `step` event. This is emitted once per frame. You can hook into it from plugins or code that exists outside of a Scene.
* Game.step now emits a `poststep` event. This is the last chance you get to do things before the render process begins.
* Optimized TextureTintPipeline.drawBlitter so it skips bobs that have alpha of zero and only calls `setTexture2D` if the bob sourceIndex has changed, previously it called it for every single bob.
* Game.context used to be undefined if running in WebGL. It is now set to be the `WebGLRenderingContext` during WebGLRenderer.init. If you provided your own custom context, it is set to this instead.
* The Game `onStepCallback` has been removed. You can now listen for the new step events instead.
* Phaser.EventEmitter was incorrectly namespaced, it's now only available under Phaser.Events.EventEmitter (thanks Tigran)

### Bug Fixes

* The Script File type in the Loader didn't create itself correctly as it was missing an argument (thanks @TadejZupancic)
* The Plugin File type in the Loader didn't create itself correctly as it was missing an argument.
* WebAudioSoundManager.unlock will now check if `document.body` is available before setting the listeners on it. Fixes old versions of Firefox, apparently. #3649 (thanks @squilibob)
* Utils.Array.BringToTop failed to move the penultimate item in an array due to an index error. Fix #3658 (thanks @agar3s)
* The Headless renderer was broken due to an invalid access during TextureSource.init.
* Animation.yoyo was ignored when calculating the next frame to advance to, breaking the yoyo effect. It now yoyos properly (thanks Tomas)
* Corrected an error in Container.getBoundsTransformMatrix that called a missing method, causing a `getBounds` on a nested container to fail. Fix #3624 (thanks @poasher)
* Calling a creator, such as GraphicsCreator, without passing in a config object, would cause an error to be thrown. All Game Object creators now catch against this.

## Version 3.7.1 - Sinon - 8th May 2018

### New Features

* The Phaser 3 Labs has gained a nifty 'search' feature box thanks to @NemoStein - it allows you to filter out the example categories.
* We've added a Mask component, which is available on nearly all Game Objects. It includes the methods `setMask`, `clearMask`, `createBitmapMask` and `createGeometryMask`.
* CanvasTexture is a new extension of the Texture object specifically created for when you've got a Canvas element as the backing source of the texture that you wish to draw to programmatically using the Canvas API. This was possible in previous versions, as a Texture object supported having a Canvas as its source, but we've streamlined the process and made it a lot easier for you to refresh the resulting WebGLTexture on the GPU. To create a CanvasTexture just call the `TextureManager.createCanvas` method as before, only this time you'll get a CanvasTexture back which has helper properties and methods. See the complete JSDocs for more details.
* RandomDataGenerator has a new method: `shuffle` which allows you to shuffle an array using the current RNG seed (thanks @wtravO)
* The Texture Manager now supports normal maps for Atlas JSON (in both hash and array formats), Atlas XML and Atlas Unity.
* All Game Objects have a new method `disableInteractive` which will disable the Interactive Object bound to them. You can toggle it back again by calling `setInteractive` with no arguments.
* All Game Objects have a new method `removeInteractive` which will destroy the Interactive Object bound to them entirely. Use this if a Game Object no longer needs any input at all but you don't want to destroy the Game Object itself.

### Loader New Features and Important Updates

The Loader has been given an overhaul to improve its performance and extensibility and gains the following new features:

* A popular feature from Phaser 2 is back: Loader Packs. These are JSON files that contain a bunch of files to load. You can now load a pack into the Loader, and it will parse it and then add the contents into the current load queue automatically. Those contents can be anything the Loader can handle, including other packs! Please see the documentation and examples for more details.
* The Loader is no longer locked during load. New files can be added into the load queue, even while a load is in process. Indeed, this is how the new Pack files feature works. A side effect is that if you do it a lot, your progress bar may jump around, as it's based on the number of files in the loader at that point in time. So if you add a bunch more it may look like it has reduced. It's up to you to handle this in your code, or create a type of loader graphic that doesn't highlight this (such as a spinning circle instead of a progress bar).
* The Loader now handles the flow slightly differently. Before, it would load every file, and once they were all complete it would then process them in turn. Which would add them into the various caches, create textures, and so on. This now happens as soon as the file has loaded because the browser is likely mostly idle during this time anyway, so it allows us to distribute the file processing throughout the load time, rather than in one lump at the end.
* Loading an Audio Sprite has changed. You now specify the JSON file first, and if you wish you can leave out the audio file URLs and let the Loader figure it out from the JSON meta data.
* The Loader has a new file type: `atlasXML` which will load a Shoebox / Starling / Flash CC format XML Texture Atlas.
* The Loader `multiatlas` file type has changed. You no longer have to specify the URLs of the images, instead it reads them from the JSON data and adds them into the loader automatically.
* Every file type the Loader supports can now be loaded either via the method arguments, or a configuration object, or an array of configuration objects. Before only some of them could, but they all use the same code now. See the new examples demonstrating this.
* If you used a Scene files payload then the format of the object has changed. It used to be a property in the Scene Config called `files` which was an array of files to load. It has been renamed to `pack` and it's an object that exactly matches the new Pack File format. Please see the loader example `scene files payload.js` for an example. In short, where you had: `files: []` before, just change it to `pack: { files: [] }` and it'll work.
* The Loader now supports Texture Atlases with normal maps. Before it would only support single images loaded with normal maps, but now you can provide them for all the atlas formats (json, xml and Unity)
* The Loader `multiatlas` feature will now automatically load texture normal maps, if specified in the json.
* Binary Files have a new optional `dataType` argument and property which will cast the binary data to that format after load, before inserting it into the cache, i.e.: `load.binary('mod', 'music.mod', Uint8Array)`
* The method `LoaderPlugin.tilemapWeltmeister` has been renamed to the far more friendly `LoaderPlugin.tilemapImpact`. Everything else about it remains the same, but please update to use the new method name.

### Loader Updates

* The Loader and all associated file types are now covered 100% by JSDocs.
* LinkFile is a new type of file used by the Loader that handles multiple files that need to be joined together. For example, loading a JSON and an Image for a Texture Atlas. This is now handled by a LinkFile.
* File has a new argument in its constructor which is an instance of the LoaderPlugin. It stores this in the `loader` property. It also has a new property `cache` which is a reference to the cache that the file type will be stored in.
* File has a new method `hasCacheConflict` which checks if a key matching the one used by this file exists in the target Cache or not.
* File has a new method `addToCache` which will add the file to its target cache and then emit a `filecomplete` event, passing its key and a reference to itself to the listener (thanks to @kalebwalton for a related PR)
* The Loader has a new property `cacheManager` which is a reference to the global game cache and is used by the File Types.
* The Loader has a new property `textureManager` which is a reference to the global Texture Manager and is used by the File Types.
* The Loader will now check to see if loading a file would cache a cache conflict or not, and prevent it if it will.
* The Loader now hands off processing of the file data to the file itself, which will now self-add itself to its target cache.
* The Loader will now call 'destroy' on all Files when it finishes processing them. They now tidy-up references and extra data, freeing them for gc.
* The File Types are now responsible for adding themselves to their respective caches and any extra processing that needs to happen. This has removed all of the code from the Loader that was doing this, meaning the file types are now properly abstracted away and the Loader is no longer bound to them. This allows you to exclude file types if you don't need them, creating smaller bundles as a result. It also means we can drop in new file types easily without touching the Loader itself and Plugins can register new file types.
* The XMLFile type will no longer throw an error if it can't parse the XML, instead it'll log a console warning and not add the XML to the cache.
* Loading a BitmapFont will add the image used as the font texture into the Texture Manager and the XML into the XML cache, using the key you specified for the font, so you can extract it more easily if needed.
* The default number of max parallel file loads has increased from 4 to 32. You can still change it in the game config.
* Normal Maps can now be loaded using a config object: `load.image({ key: 'shinyRobot', url: 'rob.png', normalMap: 'rob_n.png' });` - you can still use the previous array method too.
* Loader.enableParallel has been removed. If you don't want parallel file loads then set the maximum parallel limit to 1. Related to this, the Game Config `loaderEnableParallel` property has been removed.
* You can now set the `X-Requested-With` header in the XHR requests by specifying it in your XHRSettings config, either in the game, scene or file configs.
* Files will consider themselves as errored if the xhr status is >= 400 and <= 599, even if they didn't throw an onerror event.

### Updates

* If you're using Webpack with Phaser you'll need to update your config to match our new one. The two changes are: We've removed the need for `raw-loader` and we've changed the syntax of the DefinePlugin calls:
* We've swapped use of the Webpack DefinePlugin so instead of setting a global flag for the compilation of the Canvas and WebGL renderers, we use a typeof check instead. This means you should now be able to ingest the Phaser source more easily outside of Webpack without having to define any global vars (thanks @tgrajewski)
* Under Webpack we still no longer use `raw-loader` to import our shader source. Instead it's compiled to plain JS files during our in-house workflow. This should allow you to bundle Phaser with packages other than Webpack more easily.
* The Texture Manager will now emit an `addtexture` event whenever you add a new texture to it, which includes when you load image files from the Loader (as it automatically populates the Texture Manager). Once you receive an `addtexture` event you know the image is loaded and the texture is safe to be applied to a Game Object.
* BitmapMask and GeometryMask both have new `destroy` methods which clear their references, freeing them for gc.
* CanvasPool has a new argument `selfParent` which allows the canvas itself to be the parent key, used for later removal.
* Frame has a new method `setSize` which allows you to set the frame x, y, width and height and have it update all of the internal properties automatically. This is now called directly in the constructor.
* When a TextureSource is destroyed if it's got a canvas texture it's removed from the CanvasPool.
* TextureManager.checkKey will check if a texture key is in-use and log a console error if it is and then return a boolean. This is now used extensively internally to prevent you from adding textures that already exist into the manager. If you wish to just check if a key is in use without the error, use the `TextureManager.exists` method as before.
* TextureManager.remove will allow you to remove a texture from the manager. The texture is destroyed and it emits a `removetexture` event.
* TextureSource has a new property `renderer` as it's used a lot internally and is useful if you extend the class.
* TextureSource will now remove its respective WebGLTexture from the renderer when destroyed.
* TextureSource will now automatically create a glTexture from its canvas if using one.
* WebGLRenderer will now remove a GL texture from its local `nativeTextures` array when you call the `deleteTexture` method.
* The BaseCache has a new method `exists` that will return a boolean if an entry for the given key exists in the cache or not.
* ScenePlugin.getIndex will return the index of the given Scene in the Scene List.
* The Scene Systems will emit a `ready` event when it has fully finished starting up and all plugins are available. Re: #3636 (thanks @Yazir)
* All Game Object Creators now have an extra boolean argument `addToScene`. If you set this to `true` it will add the Game Object being created to the Scene automatically, while `false` will do the opposite, i.e.: `this.make.image(config, false)`. You can still specify the `add` property in the Config object too, but if the argument is provided it will override the property.
* We have removed the TextureManager.addAtlasPyxel method and related parser. It didn't work anyway and no-one seems to use Pyxel any more. If we get enough demand we can consider adding it back.
* When adding an Audio Sprite to the Sound Manager it will now respect the `loop` property, if set in the source JSON.
* The Texture class has a new method `getDataSourceImage` which will return the raw image data of the data source.
* The WebAudioSoundManager will now listen for 'click' events on the document body, as well as touch events, before resuming the AudioContext, in order to deal with the changes made in Chrome v66 not playing audio until a user gesture is received, even on desktop.

### Bug Fixes

* DataManagerPlugin would throw an error on Game.destroy if you had any Scenes in the Scene Manager had not been run. Fix #3596 (thanks @kuoruan)
* If you created a Game with no Scenes defined, and then added one via `Game.scene.add` and passed in a data object, the data would be ignored when starting the Scene.
* Adding a Group with an array of children in the constructor was broken since 3.5. Fix #3612 (thanks @fariazz @samme)
* Fix ParticleEmitter toJSON output, it was missing the `angle` property and the Emitter Ops were being cast wrong (thanks @samme)
* Fixed loading normals with multi image load (thanks @iamchristopher)
* Array.AddAt would fail if it branched to the fast-path within a Container due to an invalid property. Fix #3617 (thanks @poasher)
* Polygon.setTo would fail if given an array of arrays as a list of points. Fix #3619 (thanks @PaulTodd)
* Text objects with word wrapping enabled would gain an extra space at the end of the line. These are now only added when the word index is greater than the previous one. Fix #3626 (thanks @rexrainbow)
* Container.getBounds now checks if it can call `getBounds` on its children before doing so, as some do not have this method (such as Graphics objects) so they no longer cause the call to crash. Fix #3623 (thanks @poasher)
* The Animation Component `setProgress` method was setting the frame on the wrong object. Fix #3633 (thanks @benhhopkins)
* SceneManager.moveAbove wouldn't move the Scene if it was already above the target Scene. Now it moves to be directly above the target Scene no matter where in the Scene List it is.
* SceneManager.moveBelow wouldn't move the Scene if it was already below the target Scene. Now it moves to be directly below the target Scene no matter where in the Scene List it is.
* Emitter.setEmitZone was rejecting custom objects passed as the source argument because it was checking for the wrong methods (thanks @samme)
* ScenePlugin.setActive would only toggle the current Scene, not any given Scene.
* ScenePlugin.setVisible would only toggle the current Scene, not any given Scene.
* The Graphics Creator would automatically add the Graphics to the display list by mistake. The default should be to remain hidden. Fix #3637 (thanks @mikuso)
* BitmapText, both static and dynamic, can now take any data-type, including numbers, for the `text` argument in the constructor. Before they only worked via `setText` (thanks @Jelaw21)
* The Forward Diffuse Light Pipeline was hard coded to assume the normal map would be stored in the source index zero. It now correctly obtains the normal map from the frame source index, which means all Game Objects that used frames from multi-atlas textures will now work with lights properly.
* The Tiled Base64Decode function worked off the wrong array length, causing extra undefined values at the end (thanks @tamagokun)

### Examples, Documentation and TypeScript

My thanks to the following for helping with the Phaser 3 Examples, Docs and TypeScript definitions, either by reporting errors, fixing them or helping author the docs:

@wtravO @Fabadiculous @zilbuz @samme @iamchristopher @erd0s @PaNaVTEC @ksmai @snowbillr 

## Version 3.7.0 - Sinon - 4th May 2018

A beta release of the 3.7.0 version. See 3.7.1 for details.

## Version 3.6.0 - Asuna - 19th April 2018

### New Features

* Containers are now fully available! We have removed the beta warning and fixed the way in which they work with Cameras, input and scroll factors. They are also fully documented, so please see their docs and examples for use.
* Group.getLast will return the last member in the Group matching the search criteria.
* Group.getFirstNth will return the nth member in the Group, scanning from top to bottom, that matches the search criteria.
* Group.getLastNth will return the nth member in the Group, scanning in reverse, that matches the search criteria.
* Group.remove has a new optional argument `destroyChild` that will call `destroy` on the child after removing it.
* Group.clear has a new optional argument `destroyChild` that will call `destroy` on all children in the Group after removing them.

### Updates

* Impact Physics Game Objects have changed `setLite` to `setLiteCollision`.
* Impact Physics Game Objects have changed `setPassive` to `setPassiveCollision`.
* Impact Physics Game Objects have changed `setFixed` to `setFixedCollision`.
* Impact Physics Game Objects have changed `setActive` to `setActiveCollision`, previously the `setActive` collision method was overwriting the Game Objects `setActive` method, hence the renaming.
* The modifications made to the RTree class in Phaser 3.4.0 to avoid CSP policy violations caused a significant performance hit once a substantial number of bodies were involved. We have recoded how the class deals with its accessor formats and returned to 3.3 level performance while still maintaining CSP policy adherence. Fix #3594 (thanks @16patsle)
* The Retro Font namespace has changed to `Phaser.GameObjects.RetroFont`. Previously, you would access the parser and constants via `BitmapText`, i.e.: `Phaser.GameObjects.BitmapText.ParseRetroFont.TEXT_SET6`. This has now changed to its own namespace, so the same line would be: `Phaser.GameObjects.RetroFont.TEXT_SET6`. The Parser is available via `Phaser.GameObjects.RetroFont.Parse`. This keeps things cleaner and also unbinds RetroFont from BitmapText, allowing you to cleanly exclude it from your build should you wish. All examples have been updated to reflect this.
* If using the `removeFromScene` option in Group.remove or Group.clear it will remove the child/ren from the Scene to which they belong, not the Scene the Group belongs to.

### Bug Fixes

* Fixed a bug that caused data to not be passed to another Scene if you used a transition to start it. Fix #3586 (thanks @willywu)
* Group.getHandler would return any member of the Group, regardless of the state, causing pools to remain fixed at once member. Fix #3592 (thanks @samme)

## Version 3.5.1 - Kirito - 17th April 2018

### Updates

* The change made in 3.5.0 with how the Scene systems lifecycle is handled has been tweaked. When a Scene is instantiated it will now emit a boot event, as before, and Systems that need it will listen for this event and set-up their internal properties as required. They'll also do the same under the 'start' event, allowing them to restart properly once shutdown. In 3.5 if a Scene was previously not launched or started you wouldn't be able to access all of its internal systems fully, but in 3.5.1 you can.

### Bug Fixes

* LoaderPlugin.destroy would try and remove an incorrect event listener.
* TileSprites would try to call `deleteTexture` on both renderers, but it's only available in WebGL (thanks @jmcriat)
* Using a geometry mask stopped working in WebGL. Fix #3582 (thanks @rafelsanso)
* The particle emitter incorrectly adjusted the vertex count, causing WebGL rendering issues. Fix #3583 (thanks @murteira)

## Version 3.5.0 - Kirito - 16th April 2018

### Changes to Cameras

* The Camera class and all Camera effects are now fully covered by 100% complete JS Docs.
* All Camera effects have been recoded from scratch. They now follow a unified effects structure and each effect is encapsulated in its own class found in the 'effects' folder. Currently there are Fade, Flash and Shake effects.
* The new effects classes are accessed via the Camera properties `fadeEffect`, `flashEffect` and `shakeEffect`. You can still use the friendly Camera level methods: `shake`, `fade` and `flash`.
* The new structure means you can replace the default effects with your own by simply overwriting the properties with your own class.
* The effects now work properly under any combination. For example, you can fade out then in, or in then out, and still flash or shake while a fade is happening. The renderers now properly stack the effects in order to allow this.
* All of the effect related Camera properties (like `_fadeAlpha`) have been removed. If you need access to these values you can get it much more cleanly via the camera effects classes themselves. They were always private anyway, but we know some of you needed to modify them, so have been doing so from your code. This code will now need updating.
* Removed Camera.clearBeforeRender property as it was never used internally. This setting can be enabled on a Game-wide basis.
* Camera now extends the Event Emitter, allowing it to emit events.
* Camera.cullHitTest has been removed. It was never used internally and duplicates the code in `Camera.cull`.
* The `callback` property of the Camera effects methods has changed purpose. It is no longer an `onComplete` callback, but is now an `onUpdate` callback. It is invoked every frame for the duration of the effect. See the docs for argument details.
* Camera effects now dispatch events. They dispatch 'start' and 'complete' events, which can be used to handle any actions you may previously have been doing in the callback. See the effects docs and examples for the event names and arguments.
* The Camera Shake effect now lets you specify a different intensities for the x and y dimensions.
* You can track the progress of all events via the `progress` property on the effect instance, allowing you to sync effect duration with other in-game events.

### New Feature: Scene Transitions

There is a new method available in the ScenePlugin, available via: `this.scene.transition` which allows you to transition from one Scene to another over the duration specified. The method takes a configuration object which lets you control various aspects of the transition, from moving the Scenes around the display list, to specifying an onUpdate callback.

The calling Scene can be sent to sleep, stopped or removed entirely from the Scene Manager at the end of the transition, and you can even lock down input events in both Scenes while the transition is happening, if required. There are various events dispatched from both the calling and target Scene, which combined with the onUpdate callback give you the flexibility to create some truly impressive transition effects both into and out of Scenes.

Please see the complete JSDocs for the ScenePlugin for more details, as well as the new examples in the Phaser 3 Labs.

### More New Features

* GameObject.ignoreDestroy allows you to control if a Game Object is destroyed or not. Setting the flag will tell it to ignore destroy requests from Groups, Containers and even the Scene itself. See the docs for more details.
* The Scene Input Plugin has a new property `enabled` which allows you to enable or disable input processing on per Scene basis.

### Bug Fixes

* MatterEvents.off() would cause a TypeError if you destroyed the Matter world. Fix #3562 (thanks @pixelscripter)
* DynamicBitmapText was missing the `letterSpacing` property, causing it to only render the first character in WebGL (thanks @Antriel)
* The Animation component didn't properly check for the animation state in its update, causing pause / resume to fail. Fix #3556 (thanks @Antriel @siolfyr)
* The Scene Manager would never reach an `isBooted` state if you didn't add any Scenes into the Game Config. Fix #3553 (thanks @rgk)
* Fixed issue in HTMLAudioSound where `mute` would get into a recursive loop.
* Every RenderTexture would draw the same content due to a mis-use of the CanvasPool (this also impacted TileSprites). Fix #3555 (thanks @kuoruan)
* Group.add and Group.addMultiple now respect the Group.maxSize property, stopping you from over-populating a Group (thanks @samme)
* When using HTML5 Audio, sound manager now tries to unlock audio after every scene loads, instead of only after first one. Fix #3309 (thanks @pavle-goloskokovic)
* Group.createMultiple would insert null entries if the Group became full during the operation, causing errors later. Now it stops creating objects if the Group becomes full (thanks @samme)
* Group.remove didn't check if the passed Game Object was already a member of the group and would call `removeCallback` and (if specified) `destroy` in any case. Now it does nothing if the Game Object isn't a member of the group (thanks @samme)
* If a Group size exceeded `maxSize` (which can happen if you reduce maxSize beneath the current size), `isFull` would return false and the group could continue to grow. Now `isFull` returns true in that case (thanks @samme)
* Camera.fadeIn following a fadeOut wouldn't work, but is now fixed as a result of the Camera effects rewrite. Fix #3527 (thanks @Jerenaux)
* Particle Emitters with large volumes of particles would throw the error `GL_INVALID_OPERATION: Vertex buffer is not big enough for the draw call` in WebGL.
* Fixed issue with Game.destroy not working correctly under WebGL since 3.4. Fix #3569 (thanks @Huararanga)

### Updates

* Removed the following properties from BaseSound as they are no longer required. Each class that extends BaseSound implements them directly as getters: `mute`, `loop`, `seek` and `volume`.
* The Device.OS test to see if Phaser is running under node.js has been strengthened to support node-like environments like Vue (thanks @Chumper)
* Every Plugin has been updated to correctly follow the same flow through the Scene lifecycle. Instead of listening for the Scene 'boot' event, which is only dispatched once (when the Scene is first created), they will now listen for the Scene 'start' event, which occurs every time the Scene is started. All plugins now consistently follow the same Shutdown and Destroy patterns too, meaning they tidy-up after themselves on a shutdown, not just a destroy. Overall, this change means that there should be less issues when returning to previously closed Scenes, as the plugins will restart themselves properly.
* When shutting down a Scene all Game Objects that belong to the scene will now automatically destroy themselves. They would previously be removed from the display and update lists, but the objects themselves didn't self-destruct. You can control this on a per-object basis with the `ignoreDestroy` property.
* A Matter Mouse Spring will disable debug draw of its constraint by default (you can override it by passing in your own config)
* The RandomDataGenerator class is now exposed under Phaser.Math should you wish to instantiate it yourself. Fix #3576 (thanks @wtravO)
* Refined the Game.destroy sequence, so it will now only destroy the game at the start of the next frame, not during processing.

## Version 3.4.0 - Miyako - 12th April 2018

### New Features

A beta release of the new Container Game Object arrives in this version. We've flagged it as beta because there are known issues in using Containers in Scenes that have multiple cameras or irregular camera viewports. However, in all other instances we've tested they are operating normally, so we felt it would be best to release them into this build to give developers a chance to get used to them. Using a Container will issue a single console warning as a reminder. We will remove this once they leave beta in a future release. In the meantime they are fully documented and you can find numerous examples in the Phaser 3 Examples repo too.

* A new property was added to Matter.World, `correction` which is used in the Engine.update call and allows you to adjust the time being passed to the simulation. The default value is 1 to remain consistent with previous releases.
* Matter Physics now has a new config property `getDelta` which allows you to specify your own function to calculate the delta value given to the Matter Engine when it updates.
* Matter Physics has two new methods: `set60Hz` and `set30Hz` which will set an Engine update rate of 60Hz and 30Hz respectively. 60Hz being the default.
* Matter Physics has a new config and run-time property `autoUpdate`, which defaults to `true`. When enabled the Matter Engine will update in sync with the game step (set by Request Animation Frame). The delta value given to Matter is now controlled by the `getDelta` function.
* Matter Physics has a new method `step` which manually advances the physics simulation by one iteration, using whatever delta and correction values you pass in to it. When used in combination with `autoUpdate=false` you can now explicitly control the update frequency of the physics simulation and unbind it from the game step.
* Matter Physics has two new debug properties: `debugShowJoint` and `debugJointColor`. If defined they will display joints in Matter bodies during the postUpdate debug phase (only if debug is enabled) (thanks @OmarShehata)
* Group.destroy has a new optional argument `destroyChildren` which will automatically call `destroy` on all children of a Group if set to true (the default is false, hence it doesn't change the public API). Fix #3246 (thanks @DouglasLapsley)
* WebAudioSound.setMute is a chainable way to mute a single Sound instance.
* WebAudioSound.setVolume is a chainable way to set the volume of a single Sound instance.
* WebAudioSound.setSeek is a chainable way to set seek to a point of a single Sound instance.
* WebAudioSound.setLoop is a chainable way to set the loop state of a single Sound instance.
* HTML5AudioSound.setMute is a chainable way to mute a single Sound instance.
* HTML5AudioSound.setVolume is a chainable way to set the volume of a single Sound instance.
* HTML5AudioSound.setSeek is a chainable way to set seek to a point of a single Sound instance.
* HTML5AudioSound.setLoop is a chainable way to set the loop state of a single Sound instance.
* BitmapText has a new property `letterSpacing` which accepts a positive or negative number to add / reduce spacing between characters (thanks @wtravO)
* You can now pass a Sprite Sheet or Canvas as the Texture key to `Tilemap.addTileset` and it will work in WebGL, where-as before it would display a corrupted tilemap. Fix #3407 (thanks @Zykino)
* Graphics.slice allows you to easily draw a Pacman, or slice of pie shape to a Graphics object.
* List.addCallback is a new optional callback that is invoked every time a new child is added to the List. You can use this to have a callback fire when children are added to the Display List.
* List.removeCallback is a new optional callback that is invoked every time a new child is removed from the List. You can use this to have a callback fire when children are removed from the Display List.
* ScenePlugin.restart allows you to restart the current Scene. It's the same result as calling `ScenePlugin.start` without any arguments, but is more clear.
* Utils.Array.Add allows you to add one or more items safely to an array, with optional limits and callbacks.
* Utils.Array.AddAt allows you to add one or more items safely to an array at a specified position, with optional limits and callbacks.
* Utils.Array.BringToTop allows you to bring an array element to the top of the array.
* Utils.Array.CountAllMatching will scan an array and count all elements with properties matching the given value.
* Utils.Array.Each will pass each element of an array to a given callback, with optional arguments.
* Utils.Array.EachInRange will pass each element of an array in a given range to a callback, with optional arguments.
* Utils.Array.GetAll will return all elements from an array, with optional property and value comparisons.
* Utils.Array.GetFirst will return the first element in an array, with optional property and value comparisons.
* Utils.Array.GetRandomElement has been renamed to GetRandom and will return a random element from an array.
* Utils.Array.MoveDown will move the given array element down one position in the array.
* Utils.Array.MoveTo will move the given array element to the given position in the array.
* Utils.Array.MoveUp will move the given array element up one position in the array.
* Utils.Array.Remove will remove the given element or array of elements from the array, with an optional callback.
* Utils.Array.RemoveAt will remove the element from the given position in the array, with an optional callback.
* Utils.Array.RemoveBetween will remove the elements between the given range in the array, with an optional callback.
* Utils.Array.Replace will replace an existing element in an array with a new one.
* Utils.Array.SendToBack allows you to send an array element to the bottom of the array.
* Utils.Array.SetAll will set a property on all elements of an array to the given value, with optional range limits.
* Utils.Array.Swap will swap the position of two elements in an array.
* TransformMatrix.destroy is a new method that will clear out the array and object used by a Matrix internally.
* BaseSound, and by extension WebAudioSound and HTMLAudioSound, will now emit a `destroy` event when they are destroyed (thanks @rexrainbow)
* A new property was added to the Scene config: `mapAdd` which is used to extend the default injection map of a scene instead of overwriting it (thanks @sebashwa)
* GetBounds `getTopLeft`, `getTopRight`, `getBottomLeft` and `getBottomRight` all have a new optional argument `includeParent` which will factor in all ancestor transforms to the returned point.

### Bug Fixes

* In the WebGL Render Texture the tint of the texture was always set to 0xffffff and therefore the alpha values were ignored. The tint is now calculated using the alpha value. Fix #3385 (thanks @ger1995)
* The RenderTexture now uses the ComputedSize component instead of Size (which requires a frame), allowing calls to getBounds to work. Fix #3451 (thanks @kuoruan)
* PathFollower.start has been renamed to `startFollow`, but PathFollower.setPath was still using `PathFollower.start` (thanks @samid737)
* BaseSoundManager.rate and BaseSoundManager.detune would incorrectly called `setRate` on its sounds, instead of `calculateRate`.
* The Gamepad Axis `getValue` method now correctly applies the threshold and zeroes out the returned value.
* The HueToComponent module was not correctly exporting itself. Fix #3482 (thanks @jdotrjs)
* Matter.World was using `setZ` instead of `setDepth` for the Debug Graphics Layer, causing it to appear behind objects in some display lists.
* Game.destroy now checks to see if the `renderer` exists before calling destroy on it. Fix #3498 (thanks @Huararanga)
* Keyboard.JustDown and Keyboard.JustUp were being reset too early, causing them to fail when called in `update` loops. Fix #3490 (thanks @belen-albeza)
* RenderTexture.destroy no longer throws an error when called. Fix #3475 (thanks @kuoruan)
* The WebGL TileSprite batch now modulates the tilePosition to avoid large values being passed into the UV data, fixing corruption when scrolling TileSprites over a long period of time. Fix #3402 (thanks @vinerz @FrancescoNegri)
* LineCurve.getResolution was missing the `divisions` argument and always returning 1, which made it fail when used as part of a Path. It now defaults to return 1 unless specified otherwise (thanks _ok)
* A Game Object enabled for drag would no longer fire over and out events after being dragged, now it does (thanks @jmcriat)
* Line.getPointA and Line.getPointB incorrectly set the values into the Vector2 (thanks @Tomas2h)
* DynamicTilemapLayer now uses the ComputedSize component, which stops it breaking if you call `setDisplaySize` (thanks Babsobar)
* StaticTilemapLayer now uses the ComputedSize component, which stops it breaking if you call `setDisplaySize` (thanks Babsobar)
* CanvasPool.first always returned `null`, and now returns the first available Canvas. Fix #3520 (thanks @mchiasson)
* When starting a new Scene with an optional `data` argument it wouldn't get passed through if the Scene was not yet available (i.e. the game had not fully booted). The data is now passed to the Scene `init` and `create` methods and stored in the Scene Settings `data` property. Fix #3363 (thanks @pixelhijack)
* Tween.restart handles removed tweens properly and reads them back into the active queue for the TweenManager (thanks @wtravO)
* Tween.resume will now call `Tween.play` on a tween that was paused due to its config object, not as a result of having its paused method called. Fix #3452 (thanks @jazen)
* LoaderPlugin.isReady referenced a constant that no longer exists. Fix #3503 (thanks @Twilrom)
* Tween Timeline.destroy was trying to call `destroy` on Tweens instead of `stop` (thanks @Antriel)
* Calling `setOffset` on a Static Arcade Physics Body would break because the method was missing. It has been added and now functions as expected. Fix #3465 (thanks @josephjaniga and @DouglasLapsley)
* Calling Impact.World.remove(body) during a Body.updateCallback would cause the internal loop to crash when trying to access a now missing body. Two extra checks are in place to avoid this (thanks @iamDecode)
* If `setInteractive` is called on a Game Object that fails to set a hit area, it will no longer try to assign `dropZone` to an undefined `input` property.
* The Matter SetBody Component will no longer try to call `setOrigin` unless the Game Object has the origin component (which not all do, like Graphics and Container)
* Matter Image and Matter Sprite didn't define a `destroy` method, causing an error when trying to destroy the parent Game Object. Fix #3516 (thanks @RollinSafary)

### Updates

* The RTree library (rbush) used by Phaser 3 suffered from violating CSP policies by dynamically creating Functions at run-time in an eval-like manner. These are now defined via generators. Fix #3441 (thanks @jamierocks @Colbydude @jdotrjs)
* BaseSound has had its `rate` and `detune` properties removed as they are always set in the overriding class.
* BaseSound `setRate` and `setDetune` from the 3.3.0 release have moved to the WebAudioSound and HTML5AudioSound classes respectively, as they each handle the values differently.
* The file `InteractiveObject.js` has been renamed to `CreateInteractiveObject.js` to more accurately reflect what it does and to avoid type errors in the docs.
* Renamed the Camera Controls module exports for `Fixed` to `FixedKeyControl` and `Smoothed` to `SmoothedKeyControl` to match the class names. Fix #3463 (thanks @seivan)
* The ComputedSize Component now has `setSize` and `setDisplaySize` methods. This component is used for Game Objects that have a non-texture based size.
* The GamepadManager now extends EventEmitter directly, just like the KeyboardManager does.
* The Gamepad Axis threshold has been increased from 0.05 to 0.1.
* Utils.Array.FindClosestInSorted has a new optional argument `key` which will allow you to scan a top-level property of any object in the given sorted array and get the closest match to it.
* Vector2.setTo is a method alias for Vector2.set allowing it to be used inter-changeably with Geom.Point.
* List.add can now take an array or a single child. If an array is given it's passed over to List.addMultiple.
* List.add has a new optional argument `skipCallback`.
* List.addAt has a new optional argument `skipCallback`.
* List.addMultiple has a new optional argument `skipCallback`.
* List.remove has a new optional argument `skipCallback`.
* List.removeAt has a new optional argument `skipCallback`.
* List.removeBetween has a new optional argument `skipCallback`.
* List.removeAll has a new optional argument `skipCallback`.
* When using the `extend` property of a Scene config object it will now block overwriting the Scene `sys` property.
* When using the `extend` property of a Scene config object, if you define a property called `data` that has an object set, it will populate the Scenes Data Manager with those values.
* SceneManager._processing has been renamed to `isProcessing` which is now a boolean, not an integer. It's also now public and read-only.
* SceneManager.isBooted is a new boolean read-only property that lets you know if the Scene Manager has performed its initial boot sequence.
* TransformMatrix has the following new getter and setters: `a`, `b`, `c`, `d`, `tx` and `ty`. It also has the following new getters: `scaleX`, `scaleY` and `rotation`.
* List.getByKey has been removed. Use `List.getFirst` instead which offers the exact same functionality.
* List.sortIndexHandler has been removed because it's no longer required.
* List.sort no longer takes an array as its argument, instead it only sorts the List contents by the defined property.
* List.addMultiple has been removed. Used `List.add` instead which offers the exact same functionality.
* List is now internally using all of the new Utils.Array functions.
* Rectangle.Union will now cache all vars internally so you can use one of the input rectangles as the output rectangle without corrupting it.
* When shutting down a Matter World it will now call MatterEvents.off, clearing all events, and also `removeAllListeners` for any local events.
* Removed InputPlugin.sortInteractiveObjects because the method isn't used anywhere internally.

### Animation System Updates

We have refactored the Animation API to make it more consistent with the rest of Phaser 3 and to fix some issues. All of the following changes apply to the Animation Component:

* Animation durations, delays and repeatDelays are all now specified in milliseconds, not seconds like before. This makes them consistent with Tweens, Sounds and other parts of v3. You can still use the `frameRate` property to set the speed of an animation in frames per second.
* All of the Animation callbacks have been removed, including `onStart`, `onRepeat`, `onUpdate` and `onComplete` and the corresponding params arrays like `onStartParams` and the property `callbackScope`. The reason for this is that they were all set on a global level, meaning that if you had 100 Sprites sharing the same animation, it was impossible to set the callbacks to fire for just one of those Sprites, but instead they would fire for all 100 and it was up to you to figure out which Sprite you wanted to update. Instead of callbacks animations now dispatch events on the Game Objects in which they are running. This means you can now do `sprite.on('animationstart')` and it will be invoked at the same point the old `onStart` callback would have been. The new events are: `animationstart`, `animtionrepeat`, `animationupdate` and `animationcomplete`. They're all dispatched from the Game Object that has the animation playing, not from the animation itself. This allows you far more control over what happens in the callbacks and we believe generally makes them more useful.
* The AnimationFrame.onUpdate callback has been removed. You can now use the `animationupdate` event dispatched from the Game Object itself and check the 2nd argument, which is the animation frame.
* Animation.stopAfterDelay is a new method that will stop a Sprites animation after the given time in ms.
* Animation.stopOnRepeat is a new method that will stop a Sprites animation when it goes to repeat.
* Animation.stopOnFrame is a new method that will stop a Sprites animation when it sets the given frame.
* Animation.stop no longer has the `dispatchCallbacks` argument, because it dispatches an event which you can choose to ignore.
* `delay` method has been removed.
* `setDelay` allows you to define the delay before playback begins.
* `getDelay` returns the animation playback delay value.
* `delayedPlay` now returns the parent Game Object instead of the component.
* `load` now returns the parent Game Object instead of the component.
* `pause` now returns the parent Game Object instead of the component.
* `resume` now returns the parent Game Object instead of the component.
* `isPaused` returns a boolean indicating the paused state of the animation.
* `paused` method has been removed.
* `play` now returns the parent Game Object instead of the component.
* `progress` method has been removed.
* `getProgress` returns the animation progress value.
* `setProgress` lets you jump the animation to a specific progress point.
* `repeat` method has been removed.
* `getRepeat` returns the animation repeat value.
* `setRepeat` sets the number of times the current animation will repeat.
* `repeatDelay` method has been removed.
* `getRepeatDelay` returns the animation repeat delay value.
* `setRepeatDelay` sets the delay time between each repeat.
* `restart` now returns the parent Game Object instead of the component.
* `stop` now returns the parent Game Object instead of the component.
* `timeScale` method has been removed.
* `getTimeScale` returns the animation time scale value.
* `setTimeScale` sets the time scale value.
* `totalFrames` method has been removed.
* `getTotalFrames` returns the total number of frames in the animation.
* `totalProgres` method has been removed as it did nothing and was mis-spelt.
* `yoyo` method has been removed.
* `getYoyo` returns if the animation will yoyo or not.
* `setYoyo` sets if the animation will yoyo or not.
* `updateFrame` will now call `setSizeToFrame` on the Game Object, which will adjust the Game Objects `width` and `height` properties to match the frame size. Fix #3473 (thanks @wtravO @jp-gc)
* `updateFrame` now supports animation frames with custom pivot points and injects these into the Game Object origin.
* `destroy` now removes events, references to the Animation Manager and parent Game Object, clears the current animation and frame and empties internal arrays.
* Changing the `yoyo` property on an Animation Component would have no effect as it only ever checked the global property, it now checks the local one properly allowing you to specify a `yoyo` on a per Game Object basis.
* Animation.destroy now properly clears the global animation object.
* Animation.getFrameByProgress will return the Animation Frame that is closest to the given progress value. For example, in a 5 frame animation calling this method with a value of 0.5 would return the middle frame.

* Camera.fadeOut is a new method that will fade the camera out to a given color (black by default) and then optionally invoke a callback. This is the same as using Camera.fade but with an easier to grok method name. Fix #3412 (thanks @Jerenaux)
* Groups will now listen for a `destroy` event from any Game Object added to them, and if received will automatically remove that GameObject from the Group. Fix #3418 (thanks @hadikcz)
* MatterGameObject is a new function, available via the Matter Factory in `this.matter.add.gameObject`, that will inject a Matter JS Body into any Game Object, such as a Text or TileSprite object.
* Matter.SetBody and SetExistingBody will now set the origin of the Game Object to be the Matter JS sprite.xOffset and yOffset values, which will auto-center the Game Object to the origin of the body, regardless of shape.

### Bug Fixes

* Fixed the Debug draw of a scaled circle body in Arcade Physics (thanks @pixelpicosean)
* Fixed bug in `DataManager.merge` where it would copy the object reference instead of its value (thanks @rexrainbow)
* The SceneManager no longer copies over the `shutdown` and `destroy` callbacks in createSceneFromObject, as these are not called automatically and should be invoked via the Scene events (thanks @samme)
* The default Gamepad Button threshold has been changed from 0 to 1. Previously the value of 0 was making all gamepad buttons appear as if they were always pressed down (thanks @jmcriat)
* InputManager.hitTest will now factor the game resolution into account, stopping the tests from being offset if resolution didn't equal 1 (thanks @sftsk)
* CameraManager.getCamera now returns the Camera based on its name (thanks @bigbozo)
* Fixed Tile Culling for zoomed Cameras. When a Camera was zoomed the tiles would be aggressively culled as the dimensions didn't factor in the zoom level (thanks @bigbozo)
* When calling ScenePlugin.start any additional data passed to the method would be lost if the scene wasn't in an active running state (thanks @stuff)
* When calling Timeline.resetTweens, while the tweens are pending removal or completed, it would throw a TypeError about the undefined `makeActive` (thanks @allanbreyes)
* The WebGL Context would set `antialias` to `undefined` as it wasn't set in the Game Config. Fix #3386 (thanks @samme)
* The TweenManager will now check the state of a tween before playing it. If not in a pending state it will be skipped. This allows you to stop a tween immediately after creating it and not have it play through once anyway. Fix #3405 (thanks @Twilrom)
* The InputPlugin.processOverOutEvents method wasn't correctly working out the total of the number of objects interacted with, which caused input events to be disabled in Scenes further down the scene list if something was being dragged in an upper scene. Fix #3399 (thanks @Jerenaux)
* The InputPlugin.processDragEvents wasn't always returning an integer.
* LoaderPlugin.progress and the corresponding event now factor in both the list size and the inflight size when calculating the percentage complete. Fix #3384 (thanks @vinerz @rblopes @samme)
* Phaser.Utils.Array.Matrix.RotateLeft actually rotated to the right (thanks @Tomas2h)
* Phaser.Utils.Array.Matrix.RotateRight actually rotated to the left (thanks @Tomas2h)
* When deleting a Scene from the SceneManager it would set the key in the scenes has to `undefined`, preventing you from registering a new Scene with the same key. It's now properly removed from the hash(thanks @macbury)
* Graphics.alpha was being ignored in the WebGL renderer and is now applied properly to strokes and fills. Fix #3426 (thanks @Ziao)
* The font is now synced to the context in Text before running a word wrap, this ensures the wrapping result between updating the text and getting the wrapped text is the same. Fix #3389 (thanks @rexrainbow)
* Added the ComputedSize component to the Text Game Object, which allows Text.getBounds, and related methods, to work again instead of returning NaN.
* Group.remove now calls the `removeCallback` and passes it the child that was removed (thanks @orblazer)

### Updates

* The Text testString has changed from `|MÉqgy` to `|MÉqgy`.
* The WebGLRenderer width and height values are now floored when multiplied by the resolution.

* The GameObject `destroy` event is now emitted at the start of the destroy process, before things like the body or input managers have been removed, so you're able to use the event handler to extract any information you require from the GameObject before it's actually disposed of. Previously, the event was dispatched at the very end of the process.
* Phaser 3 is now built with Webpack v4.1.1 and all related packages have been updated (thanks @orblazer)

## Version 3.2.1 - 12th March 2018

### Bug Fixes

* Fixed issue with Render Texture tinting. Fix #3336 (thanks @rexrainbow)
* Fixed Utils.String.Format (thanks @samme)
* The Matter Debug Layer wouldn't clear itself in canvas mode. Fix #3345 (thanks @samid737)
* TimerEvent.remove would dispatch the Timer event immediately based on the opposite of the method argument, making it behave the opposite of what was expected. It now only fires when requested (thanks @migiyubi)
* The TileSprite Canvas Renderer did not support rotation, scaling or flipping. Fix #3231 (thanks @TCatshoek)
* Fixed Group doesn't remove children from Scene when cleared with the `removeFromScene` argument set (thanks @iamchristopher)
* Fixed an error in the lights pipeline when no Light Manager has been defined (thanks @samme)
* The ForwardDiffuseLightPipeline now uses `sys.lights` instead of the Scene variable to avoid errors due to injection removal.
* Phaser.Display.Color.Interpolate would return NaN values because it was loading the wrong Linear function. Fix #3372 (thanks @samid737)
* RenderTexture.draw was only drawing the base frame of a Texture. Fix #3374 (thanks @samid737)
* TileSprite scaling differed between WebGL and Canvas. Fix #3338 (thanks @TCatshoek)
* Text.setFixedSize was incorrectly setting the `text` property instead of the `parent` property. Fix #3375 (thanks @rexrainbow)
* RenderTexture.clear on canvas was using the last transform state, instead of clearing the whole texture.

### Updates

* The SceneManager.render will now render a Scene as long as it's in a LOADING state or higher. Before it would only render RUNNING scenes, but this precluded those that were loading assets.
* A Scene can now be restarted by calling `scene.start()` and providing no arguments (thanks @migiyubi)
* The class GameObject has now been exposed, available via `Phaser.GameObjects.GameObject` (thanks @rexrainbow)
* A Camera following a Game Object will now take the zoom factor of the camera into consideration when scrolling. Fix #3353 (thanks @brandonvdongen)
* Calling `setText` on a BitmapText object will now recalculate its display origin values. Fix #3350 (thanks @migiyubi)
* You can now pass an object to Loader.atlas, like you you can with images. Fix #3268 (thanks @TCatshoek)
* The `onContextRestored` callback won't be defined any more unless the WebGL Renderer is in use in the following objects: BitmapMask, Static Tilemap, TileSprite and Text. This should allow those objects to now work in HEADLESS mode. Fix #3368 (thanks @16patsle)
* The SetFrame method now has two optional arguments: `updateSize` and `updateOrigin` (both true by default) which will update the size and origin of the Game Object respectively. Fix #3339 (thanks @Jerenaux)

## Version 3.2.0 - Kaori - 5th March 2018

### New Features

* The new Render Texture Game Object is now available. You can clear, fill and draw texture frames to it. The Render Texture itself can be displayed in-game with its own transform, or you can use it as a Bitmap Mask for another Game Object.
* Game.resize allows you to resize the game config, renderer and input system in one call.
* When Game.resize is called it causes all Scene.Systems to have their resize method called. This is turn emits a `resize` event which your Scene can respond to. It will be sent the new width and height of the canvas as the only two parameters.
* InputManager.resize allows you to update the bounds def and input scale in one call.
* Game.Config.roundPixels property added to prevent sub-pixel interpolation during rendering of Game Objects in WebGL and Canvas.
* Load.plugin now accepts a class as an argument as well as a URL string (thanks @nkholski)
* Tween.complete will allow you to flag a tween as being complete, no matter what stage it is at. If an onComplete callback has been defined it will be invoked. You can set an optional delay before this happens (thanks @Jerenaux for the idea)
* The Headless render mode has been implemented. You can now set HEADLESS as the `renderType` in the Game Config and it will run a special game step that skips rendering. It will still create a Canvas element, as lots of internal systems (like input) rely on it, but it will not draw anything to it. Fix #3256 (thanks @rgk)
* GameObject.setInteractive has a new boolean argument `dropZone` which will allow you to set the object as being a drop zone right from the method.
* Sprites can now be drop zones and have other Game Objects dragged onto them as targets.
* The SceneManager has a new method: `remove` which allows you to remove and destroy a Scene, freeing up the Scene key for use by future scenes and potentially clearing the Scene from active memory for gc.
* SceneManager.moveAbove will move a Scene to be directly above another Scene in the Scenes list. This is also exposed in the ScenePlugin.
* SceneManager.moveBelow will move a Scene to be directly below another Scene in the Scenes list. This is also exposed in the ScenePlugin.
* Quadratic Bezier Interpolation has been added to the Math.Interpolation functions (thanks @RiCoTeRoX)
* A new Quadratic Bezier Curve class has been added, expanding the available Curve types (thanks @RiCoTeRoX)
* Path.quadraticBezierTo allows you to add a Quadratic Bezier Curve into your Path.
* Loader.multiatlas now supports Texture Packers new JSON atlas format which exports one combined atlas for all image files. This is available if you use the new Phaser 3 Export from within Texture Packer (thanks @CodeAndWeb)
* Modified WebGLPipeline to make it easier to extend and easier to create custom rendering passes.

### Bug Fixes

* Arcade Physics Bodies didn't apply the results of `allowRotation` to the parent Game Object.
* InputManager.updateBounds wouldn't correctly get the bounds of the canvas if it had horizontal or vertical translation in the page, causing the scale factor to be off (and subsequently input values to mis-fire)
* TileSprite.setFrame now works and allows you to change the frame to any other in the texture. Fix #3232 (thanks @Jerenaux)
* Swapped the queue loop in the SceneManager to to use `_queue.length` rather than a cached length (thanks @srobertson421)
* When calling `ScenePlugin.launch` the `data` argument is now passed to the queued scenes (thanks @gaudeon)
* Rectangle.top wouldn't reset the `y` position if the value given never exceed the Rectangles bottom. Fix #3290 (thanks @chancezeus)
* The implementation of `topOnly` within the Input Manager had broken the way drop zones worked, as they were now filtered out of the display list before processing. Drop zones are now treated on their own in the Input Plugin meaning you can still have `topOnly` set and still drop an item into a drop zone. This indirectly fixed #3291 (thanks @rexrainbow)
* InputPlugin.clear now properly removes a Game Object from all internal arrays, not just the _list.
* InputPlugin.processOverOut no longer considers an item as being 'out' if it's in the internal `_drag` array.
* When a Game Object is scaled, its Arcade Physics body was still calculating its position based on its original size instead of scaled one (thanks @pixelpicosean)
* The RandomDataGenerator classes randomness has been improved thanks to the correct caching of a class property. Fix #3289 (thanks @migiyubi)
* The RandomDataGenerator `sign` property had a method collision. Fix #3323 (thanks @vinerz and @samme)
* In Arcade Physics World if you collided a group with itself it would call a missing method (`collideGroupVsSelf`), it now calls `collideGroupVsGroup` correctly (thanks @patrickgalbraith)
* The HTML5 Sound Manager would unlock the Sound API on a touch event but only if the audio files were loaded in the first Scene, if they were loaded in a subsequent Scene the audio system would never unlock. It now unlocks only if there are audio files in the cache. Fix #3311 (thanks @chancezeus)
* The Text.lineSpacing value was not taken into account when rendering the Text. Fix #3215 (thanks @sftsk)
* InputPlugin.update now takes the totals from the drag and pointerup events into consideration when deciding to fall through to the Scene below. Fix #3333 (thanks @chancezeus)

### Updates

* AnimationComponent.play now calls `setSizeToFrame()` and `updateDisplayOrigin()` on the parent Game Object in order to catch situations where you've started playing an animation on a Game Object that uses a different size to the previously set frame.
* Text.setText will check if the value given is falsey but not a zero and set to an empty string if so.
* BitmapText.setText will check if the value given is falsey but not a zero and set to an empty string if so.
* BitmapText.setText will now cast the given value to a string before setting.
* BitmapText.setText will not change the text via `setText` unless the new text is different to the old one.
* If you set `transparent` in the Game Config but didn't provide a `backgroundColor` then it would render as black. It will now be properly transparent. If you do provide a color value then it must include an alpha component.
* You can now pass normal Groups to Arcade Physics collide / overlap, as well as Physics Groups. Fix #3277 (thanks @nkholski)
* Texture.get has been optimized to fail first, then error, with a new falsey check. This allows you to skip out specifying animation frames in the animation config without generating a console warning.
* The `setFrame` method of the Texture component has been updated so that it will now automatically reset the `width` and `height` of a Game Object to match that of the new Frame. Related, it will also adjust the display origin values, because they are size based. If the Frame has a custom pivot it will set the origin to match the custom pivot instead.
* ScenePlugin.swapPosition now allows you to use it to swap the positions of any two Scenes. Before the change it only allowed you to swap the position of the calling Scene and another one, but a new optional `keyB` argument opens this up.
* The SceneManager no longer renders a Scene unless it is visible AND either running or paused. This now skips Scenes that are in an `init` state.
* The Keyboard Manager will now no longer emit `keydown` events if you keep holding a key down. Fix #3239 (thanks @squaresun)
* The SceneManager now employs a new queue for all pending Scenes, creating them and booting them in strict sequence. This should prevent errors where Scenes were unable to reference other Scenes further down the boot list in their create functions. Fix #3314 (thanks @max1701 @rblopes)
* Game.preBoot and Game.postBoot callbacks now pass an instance of the game to the callback (thanks @rblopes)
* Graphics.arc in WebGL mode now works more like arc does in Canvas (thanks @Twilrom)
* GameObjects now emit a 'destroy' event when they are destroyed, which you can use to perform any additional processing you require. Fix #3251 (thanks @rexrainbow)
* If an HTML5AudioSound sound fails to play it will now issue a console.warn (thanks @samme)
* Phaser is now running Travis CI build testing again (thanks @vpmedia)
* Documentation updates: thanks to @melissaelopez @samme @jblang94 

## Version 3.1.2 - 23rd February 2018

### Updates

* Hundreds of JSDoc fixes across the whole API.
* Tween.updateTweenData will now check to see if the Tween target still exists before trying to update its properties.
* If you try to use a local data URI in the Loader it now console warns instead of logs (thanks @samme)

### Bug Fixes

* The KeyCode `FORWAD_SLASH` had a typo and has been changed to `FORWARD_SLASH`. Fix #3271 (thanks @josedarioxyz)
* Fixed issue with vertex buffer creation on Static Tilemap Layer, causing tilemap layers to appear black. Fix #3266 (thanks @akleemans)
* Implemented Static Tilemap Layer scaling and Tile alpha support.
* Fixed issue with null texture on Particle Emitter batch generation. This would manifest if you had particles with blend modes on-top of other images not appearing.
* Added missing data parameter to ScenePlugin. Fixes #3810 (thanks @AleBles)

## Version 3.1.1 - 20th February 2018

### Updates

* The entire codebase now passes our eslint config (which helped highlight a few errors), if you're submitting a PR, please ensure your PR passes the config too.
* The Web Audio Context is now suspended instead of closed to allow for prevention of 'Failed to construct AudioContext: maximum number of hardware contexts reached' errors from Chrome in a hot reload environment. We still strongly recommend reusing the same context in a production environment. See [this example](http://labs.phaser.io/view.html?src=src%5Caudio%5CWeb%20Audio%5CReuse%20AudioContext.js) for details. Fixes #3238 (thanks @z0y1 @Ziao)
* The Webpack shell plugin now fires on `onBuildExit`, meaning it'll update the examples if you use `webpack watch` (thanks @rblopes)
* Added `root: true` flag to the eslint config to stop it scanning further-up the filesystem.

### Bug Fixes

* Math.Fuzzy.Floor had an incorrect method signature.
* Arcade Physics World didn't import GetOverlapX or GetOverlapY, causing `separateCircle` to break.
* TileSprite was missing a gl reference, causing it to fail during a context loss and restore.
* The Mesh Game Object Factory entry had incorrect arguments passed to Mesh constructor.
* Removed unused `_queue` property from `ScenePlugin` class (thanks @rblopes)
* The variable `static` is no longer used in Arcade Physics, fixing the 'static is a reserved word' in strict mode error (thanks @samme)
* Fixed `Set.union`, `Set.intersect` and `Set.difference` (thanks @yupaul)
* The corner tints were being applied in the wrong order. Fixes #3252 (thanks @Rybar)
* BitmapText objects would ignore calls to setOrigin. Fixes #3249 (thanks @amkazan)
* Fixed a 1px camera jitter and bleeding issue in the renderer. Fixes #3245 (thanks @bradharms)
* Fixed the error `WebGL: INVALID_ENUM: blendEquation: invalid mode.` that would arise on iOS. Fixes #3244 (thanks @Ziao)
* The `drawBlitter` function would crash if `roundPixels` was true. Fixes #3243 (thanks @Jerenaux and @vulcanoidlogic)

## Version 3.1.0 - Onishi - 16th February 2018

### Updates

* Vertex resource handling code updated, further optimizing the WebGL batching. You should now see less gl ops per frame across all batches.
* The `Blitter` game object has been updated to use the `List` structure instead of `DisplayList`.
* Arcade Physics World `disableBody` has been renamed `disableGameObjectBody` to more accurately reflect what it does.
* Lots of un-used properties were removed from the Arcade Physics Static Body object.
* Arcade Physics Static Body can now refresh itself from its parent via `refreshBody`.

### Bug Fixes

* A couple of accidental uses of `let` existed, which broke Image loading in Safari # (thanks Yat Hin Wong)
* Added the static property `Graphics.TargetCamera` was added back in which fixed `Graphics.generateTexture`.
* The SetHitArea Action now calls `setInteractive`, fixing `Group.createMultiple` when a hitArea has been set.
* Removed rogue Tween emit calls. Fix #3222 (thanks @ZaDarkSide)
* Fixed incorrect call to TweenManager.makeActive. Fix #3219 (thanks @ZaDarkSide)
* The Depth component was missing from the Zone Game Object. Fix #3213 (thanks @Twilrom)
* Fixed issue with `Blitter` overwriting previous objects vertex data.
* The `Tile` game object tinting was fixed, so tiles now honor alpha values correctly.
* The `BitmapMask` would sometimes incorrectly bind its resources.
* Fixed the wrong Extend target in MergeXHRSettings (thanks @samme)

### New Features

* Destroying a Game Object will now call destroy on its physics body, if it has one set.
* Arcade Physics Colliders have a new `name` property and corresponding `setName` method.
* Matter.js bodies now have an inlined destroy method that removes them from the World.
* Impact bodies now remove themselves from the World when destroyed.
* Added Vector2.ZERO static property.
