* 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)
* 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)
* 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)
* 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)
* Keyboard.JustDown and Keyboard.JustUp were being reset too early, causing them to fail when called in `update` loops. Fix #3490 (thanks @belen-albeza)
* 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)
* 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.
Also, my thanks to the following for helping with the Phaser 3 Examples and Docs, either by reporting errors, fixing them or helping author the docs: @gabegordon@melissaelopez@samid737@nbs@tgrajewski@pagesrichie@hexus@mbrickn@erd0s@icbat@Matthew-Herman
A special mention must go to @orblazer for their outstanding assistance in helping to complete the JSDoc data-types, callbacks and type defs across the API.
* Game.Config.premultipliedAlpha is now passed to the WebGL Renderer as the premultipliedAlpha context property (default `true`).
* You can now specify all of the renderer config options within a `render` object in the config. If no `render` object is found, it will scan the config object directly for the properties.
* Group.create has a new optional argument: `active` which will set the active state of the child being created (thanks @samme)
* Group.create has a new optional argument: `active` which will set the active state of the child being created (thanks @samme)
* Group.createMultiple now allows you to include the `active` property in the config object (thanks @samme)
* TileSprite has a new method: `setTilePosition` which allows you to set the tile position in a chained called (thanks @samme)
* Added the new Action - WrapInRectangle. This will wrap each items coordinates within a rectangles area (thanks @samme)
* Arcade Physics has the new methods `wrap`, `wrapArray` and `wrapObject` which allow you to wrap physics bodies around the world bounds (thanks @samme)
* The Tweens Timeline has a new method: `makeActive` which delegates control to the Tween Manager (thanks @allanbreyes)
* Actions.PropertyValueInc is a new action that will increment any property of an array of objects by the given amount, using an optional step value, index and iteration direction. Most Actions have been updated to use this internally.
* Actions.PropertyValueSet is a new action that will set any property of an array of objects to the given value, using an optional step value, index and iteration direction. Most Actions have been updated to use this internally.
* Camera.fadeIn is a new method that will fade the camera in from a given color (black by default) and then optionally invoke a callback. This is the same as using Camera.flash but with an easier to grok method name. Fix #3412 (thanks @Jerenaux)
* 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.
* 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)
* 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)
* The WebGL Context now sets `premultipliedAlpha` to `true` by default, this prevents the WebGL context from rendering as plain white under certain versions of macOS Safari.
* Line.getPointA now returns a Vector2 instead of an untyped object. It also now has an optional argument that allows you to pass a vec2 in to be populated, rather than creating a new one.
* Line.getPointB now returns a Vector2 instead of an untyped object. It also now has an optional argument that allows you to pass a vec2 in to be populated, rather than creating a new one.
* Rectangle.getLineA now returns a Line instead of an untyped object. It also now has an optional argument that allows you to pass a Line in to be populated, rather than creating a new one.
* Rectangle.getLineB now returns a Line instead of an untyped object. It also now has an optional argument that allows you to pass a Line in to be populated, rather than creating a new one.
* Rectangle.getLineC now returns a Line instead of an untyped object. It also now has an optional argument that allows you to pass a Line in to be populated, rather than creating a new one.
* Rectangle.getLineD now returns a Line instead of an untyped object. It also now has an optional argument that allows you to pass a Line in to be populated, rather than creating a new one.
* Triangle.getLineA now returns a Line instead of an untyped object. It also now has an optional argument that allows you to pass a Line in to be populated, rather than creating a new one.
* Triangle.getLineB now returns a Line instead of an untyped object. It also now has an optional argument that allows you to pass a Line in to be populated, rather than creating a new one.
* Triangle.getLineC now returns a Line instead of an untyped object. It also now has an optional argument that allows you to pass a Line in to be populated, rather than creating a new one.
* 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.
* 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)
* 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.
* 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)
* 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.
* 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.
* 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)
* 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.
* 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)
* 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)
* 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 `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)
* 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)
* 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.
* 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 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)
* 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)
* 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.
* 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.
