phaser/CHANGELOG-v3.50.md

Version 3.50.0 - Subaru - in development

WebGL Pipeline Updates

If you use a custom WebGL Pipeline in your game, you must update your code in order to use Phaser 3.50.

Due to the huge amount of work that has taken place in this area, all of the pipelines have been renamed. If you extend any of these pipelines or use them in your game code (referenced by name), then please update accordingly. The name changes are:

• TextureTintPipeline is now called the MultiPipeline.
• TextureTintStripPipeline is now called the RopePipeline.
• ForwardDiffuseLightPipeline is now called the LightPipeline.

To match the new pipeline names, the shader source code has also been renamed.

• ForwardDiffuse.frag is now called Light.frag.
• TextureTint.frag is now called Multi.frag.
• TextureTint.vert is now called Multi.vert.

Other pipeline changes are as follows:

• Types.Renderer.WebGL.WebGLPipelineConfig is a new TypeDef that helps you easily configure your own Custom Pipeline when using TypeScript and also provides better JSDocs.
• Types.Renderer.WebGL.WebGLPipelineAttributesConfig is a new TypeDef that helps you easily configure the attributes for your own Custom Pipelines when using TypeScript and also provides better JSDocs.
• All pipelines will now work out the renderer property automatically, so it's no longer required in the config.
• All pipelines will now work out the gl property automatically, so it's no longer required in the config.
• All pipelines will now extract the name property from the config, allowing you to set it externally.
• All pipelines will now extract the vertexCapacity property from the config, allowing you to set it externally.
• All pipelines will now extract the vertexSize property from the config, allowing you to set it externally.
• All pipelines will now extract the vertexData property from the config, allowing you to set it externally.
• All pipelines will now extract the attributes property from the config, allowing you to set it externally.
• All pipelines will now extract the topology property from the config, allowing you to set it externally.
• The WebGLPipeline.shouldFlush method now accepts an optional parameter amount. If given, it will return true if when the amount is added to the vertex count it will exceed the vertex capacity. The Multi Pipeline has been updated to now use this method instead of performing the comparison multiple times itself.

Pipeline Manager

The WebGL.PipelineManager is a new class that is responsbile for managing all of the WebGL Pipelines in Phaser. An instance of the Pipeline Manager is created by the WebGL Renderer and is available under the pipelines property. This means that the WebGL Renderer no longer handles pipelines directly, causing the following API changes:

• WebGLRenderer.pipelines is no longer a plain object containing pipeline instances. It's now an instance of the PipelineManager class. This instance is created during the init and boot phase of the renderer.
• The WebGLRenderer.currentPipeline property no longer exists, instead use PipelineManager.current.
• The WebGLRenderer.previousPipeline property no longer exists, instead use PipelineManager.previous.
• The WebGLRenderer.hasPipeline method no longer exists, instead use PipelineManager.has.
• The WebGLRenderer.getPipeline method no longer exists, instead use PipelineManager.get.
• The WebGLRenderer.removePipeline method no longer exists, instead use PipelineManager.remove.
• The WebGLRenderer.addPipeline method no longer exists, instead use PipelineManager.add.
• The WebGLRenderer.setPipeline method no longer exists, instead use PipelineManager.set.
• The WebGLRenderer.rebindPipeline method no longer exists, instead use PipelineManager.rebind.
• The WebGLRenderer.clearPipeline method no longer exists, instead use PipelineManager.clear.

The Pipeline Manager also offers the following new features:

• The PipelineManager.resize method automatically handles resize events across all pipelines.
• The PipelineManager.preRender method calls the pre-render method of all pipelines.
• The PipelineManager.render method calls the render method of all pipelines.
• The PipelineManager.postRender method calls the post-render method of all pipelines.
• The PipelineManager.setMulti method automatically binds the Multi Texture Pipeline, Phaser's default.
• The PipelineManager.clear method will clear the pipeline, store it in previous and free the renderer.
• The PipelineManager.rebind method will reset the rendering context and restore the previous pipeline, if set.

New constants have been created to help you reference a pipeline without needing to use strings:

• Phaser.Renderer.WebGL.Pipelines.BITMAPMASK_PIPELINE for the Bitmap Mask Pipeline.
• Phaser.Renderer.WebGL.Pipelines.LIGHT_PIPELINE for the Light 2D Pipeline.
• Phaser.Renderer.WebGL.Pipelines.SINGLE_PIPELINE for the Single Pipeline.
• Phaser.Renderer.WebGL.Pipelines.MULTI_PIPELINE for the Multi Pipeline.
• Phaser.Renderer.WebGL.Pipelines.ROPE_PIPELINE for the Rope Pipeline.

All Game Objects have been updated to use the new constants and Pipeline Manager.

Single Pipeline

There is also a new pipeline called SinglePipeline, created to emulate the old TextureTintPipeline. This special pipeline uses just a single texture and makes things a lot easier if you wish to create a custom pipeline, but not have to recode your shaders to work with multiple textures. Instead, just extend SinglePipeline, where-as before you extended the TextureTintPipeline and you won't have to change any of your shader code. However, if you can, you should update it to make it perform faster, but that choice is left up to you.

WebGL Multi-Texture Rendering

The Multi Pipeline (previously called the Texture Tint Pipeline) has had its core flow rewritten to eliminate the need for constantly creating batch objects. Instead, it now supports the new multi-texture shader, vastly increasing rendering performance, especially on draw-call bound systems.

All of the internal functions, such as batchQuad and batchSprite have been updated to use the new method of texture setting. The method signatures all remain the same unless indicated below.

• Config.render.maxTextures is a new game config setting that allows you to control how many texture units will be used in WebGL.

• WebGLRenderer.textureIndexes is a new read-only array that contains all of the available WebGL texture units.
• WebGLRenderer.tempTextures is a new read-only array that contains temporary WebGL textures.
• The WebGLRenderer.currentTextures property has been removed, as it's no longer used.
• TextureSource.glIndex is a new property that holds the currently assigned texture unit for the Texture Source.
• TextureSource.glIndexCounter is a new property that holds the time the index was assigned to the Texture Source.

• The Texture Tint Pipeline has a new attribute, inTexId which is a gl.FLOAT.
• TextureTintPipeline.bind is a new method that sets the uMainSampler uniform.
• The TextureTintPipeline.requireTextureBatch method has been removed, as it's no longer required.
• The TextureTintPipeline.pushBatch method has been removed, as it's no longer required.
• The TextureTintPipeline.maxQuads property has been removed, as it's no longer required.
• The TextureTintPipeline.batches property has been removed, as it's no longer required.
• TextureTintPipeline.flush has been rewritten to support multi-textures.
• TextureTintPipeline.flush no longer creates a sub-array if the batch is full, but instead uses bufferData for speed.
• WebGLPipeline.currentUnit is a new property that holds the most recently assigned texture unit. Treat as read-only.
• WebGLRenderer.setTextureSource is a new method, used by pipelines and Game Objects, that will assign a texture unit to the given Texture Source.
• The WebGLRenderer.setTexture2D method has been updated to use the new texture unit assignment. It no longer takes the textureUnit or flush parameters and these have been removed from its method signature.
• WebGLRenderer.setTextureZero is a new method that activates texture zero and binds the given texture to it. Useful for fbo backed game objects.
• WebGLRenderer.clearTextureZero is a new method that clears the texture that was bound to unit zero.
• WebGLRenderer.textureZero is a new property that holds the currently bound unit zero texture.
• WebGLRenderer.normalTexture is a new property that holds the currently bound normal map (texture unit one).
• WebGLRenderer.setNormalMap is a new method that sets the current normal map texture.
• WebGLRenderer.clearNormalMap is a new method that clears the current normal map texture.
• WebGLRenderer.resetTextures is a new method that flushes the pipeline, resets all textures back to the temporary ones, and resets the active texture counter.
• WebGLPipeline.boot will now check all of the attributes and store the pointer location within the attribute entry.
• WebGLPipeline.bind no longer looks-up and enables every attribute, every frame. Instead, it uses the cached pointer location stored in the attribute entry, cutting down on redundant WebGL operations.
• WebGLRenderer.isNewNormalMap is a new method that returns a boolean if the given parameters are not currently used.
• WebGLPipeline.forceZero is a new property that informs Game Objects if the pipeline requires a zero bound texture unit.
• WebGLPipeline.setAttribPointers is a new method that will set the vertex attribute pointers for the pipeline.
• WebGLRenderer.unbindTextures is a new method that will activate and then null bind all WebGL textures.
• Renderer.WebGL.Utils.parseFragmentShaderMaxTextures is a new function that will take fragment shader source and search it for %count% and %forloop% declarations, replacing them with the required GLSL for multi-texture support, returning the modified source.

Light Pipeline Changes

The Light Pipeline (previously called the Forward Diffuse Light Pipeline), which is responsible for rendering lights under WebGL, has been rewritten to work with the new Multi Pipeline features. Lots of redundant code has been removed and the following changes and improvements took place:

• The pipeline now works with Game Objects that do not have a normal map. They will be rendered using the new default normal map, which allows for a flat light effect to pass over them and merge with their diffuse map colors.
• Fixed a bug in the way lights were handled that caused Tilemaps to render one tile at a time, causing massive slow down. They're now batched properly, making a combination of lights and tilemaps possible again.
• The Bitmap Text (Static and Dynamic) Game Objects now support rendering with normal maps.
• The TileSprite Game Objects now support rendering with normal maps.
• Mesh and Quad Game Objects now support rendering with normal maps.
• The Graphics Game Objects now support rendering in Light2d. You can even use normal map textures for the texture fills.
• Particle Emitter Game Object now supports rendering in Light2d.
• All Shape Game Objects (Rectangle, IsoBox, Star, Polygon, etc) now support rendering in Light2d.
• The Text Game Object now supports rendering in Light2d, no matter which font, stroke or style it is using.
• Both Static and Dynamic Tilemap Layer Game Objects now support the Light2d pipeline, with or without normal maps.
• The pipeline will no longer look-up and set all of the light uniforms unless the Light is dirty.
• The pipeline will no longer reset all of the lights unless the quantity of lights has changed.
• The ForwardDiffuseLightPipeline.defaultNormalMap property has changed, it's now an object with a glTexture property that maps to the pipelines default normal map.
• The ForwardDiffuseLightPipeline.boot method has been changed to now generate a default normal map.
• The ForwardDiffuseLightPipeline.onBind method has been removed as it's no longer required.
• The ForwardDiffuseLightPipeline.setNormalMap method has been removed as it's no longer required.
• ForwardDiffuseLightPipeline.bind is a new method that handles setting-up the shader uniforms.
• The ForwardDiffuseLightPipeline.batchTexture method has been rewritten to use the Texture Tint Pipeline function instead.
• The ForwardDiffuseLightPipeline.batchSprite method has been rewritten to use the Texture Tint Pipeline function instead.
• ForwardDiffuseLightPipeline.lightCount is a new property that stores the previous number of lights rendered.
• ForwardDiffuseLightPipeline.getNormalMap is a new method that will look-up and return a normal map for the given object.

Lights

• Light.dirty is a new property that controls if the light is dirty, or not, and needs its uniforms updating.
• Light has been recoded so that all of its properties are now setters that activate its dirty flag.
• LightsManager.destroy will now clear the lightPool array when destroyed, where-as previously it didn't.
• LightsManager.cull now takes the viewport height from the renderer instead of the game config (thanks zenwaichi)

WebGL ModelViewProjection API Changes

The ModelViewProjection object contained a lot of functions that Phaser never used internally. These have now been moved to external functions, which can be easily excluded from Custom builds to save space.

If you used any of them in your code, please update to the new function names below:

• Phaser.Renderer.WebGL.MVP is a new namespace under which the Model View Projection functions now live.
• projIdentity is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ProjectIdentity
• projPersp is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ProjectPerspective
• modelRotateX is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.RotateX
• modelRotateY is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.RotateY
• modelRotateZ is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.RotateZ
• viewLoad is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ViewLoad
• viewRotateX is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ViewRotateX
• viewRotateY is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ViewRotateY
• viewRotateZ is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ViewRotateZ
• viewScale is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ViewScale
• viewTranslate is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ViewTranslate

• modelTranslate is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.Translate
• viewIdentity is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ViewIdentity
• viewLoad2D is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ViewLoad2D
• projOrtho is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.ProjectOrtho
• Phaser.Renderer.WebGL.MVP.SetIdentity is a new function the others use, to save on space.

BitmapText - New Features, Updates and API Changes

• BitmapText.setCharacterTint is a new method that allows you to set a tint color (either additive or fill) on a specific range of characters within a static Bitmap Text. You can specify the start and length offsets and per-corner tint colors.
• BitmapText.setWordTint is a new method that allows you to set a tint color (either additive or fill) on all matching words within a static Bitmap Text. You can specify the word by string, or numeric offset, and the number of replacements to tint.
• BitmapText.setDropShadow is a new method that allows you to apply a drop shadow effect to a Bitmap Text object. You can set the horizontal and vertical offset of the shadow, as well as the color and alpha levels. Call this method with no parameters to clear a shadow.
• BitmapTextWebGLRenderer has been rewritten from scratch to make use of the new pre-cached WebGL uv texture and character location data generated by GetBitmapTextSize. This has reduced the number of calculations made in the function dramatically, as it no longer has work out glyph advancing or offsets during render, but only when the text content updates.
• BitmapText.getCharacterAt is a new method that will return the character data from the BitmapText at the given x and y coordinates. The character data includes the code, position, dimensions, and glyph information.
• The BitmapTextSize object returned by BitmapText.getTextBounds has a new property called characters which is an array that contains the scaled position coordinates of each character in the BitmapText, which you could use for tasks such as determining which character in the BitmapText was clicked.
• ParseXMLBitmapFont will now calculate the WebGL uv data for the glyphs during parsing. This avoids it having to be done during rendering, saving CPU cycles on an operation that never changes.
• ParseXMLBitmapFont will now create a Frame object for each glyph. This means you could, for example, create a Sprite using the BitmapText texture and the glyph as the frame key, i.e.: this.add.sprite(x, y, fontName, 'A').
• BitmapTextWord, BitmapTextCharacter and BitmapTextLines are three new type defs that are now part of the BitmapTextSize config object, as returned by getTextBounds. This improves the TypeScript defs and JS Docs for this object.
• The signature of the ParseXMLBitmapFont function has changed. The frame parameter is no longer optional, and is now the second parameter in the list, instead of being the 4th. If you call this function directly, please update your code.
• The BitmapText.getTextBounds method was being called every frame, even if the bounds didn't change, potentially costing a lot of CPU time depending on the text length and quantity of them. It now only updates the bounds if they change.
• The GetBitmapTextSize function used Math.round on the values, if the round parameter was true, which didn't create integers. It now uses Math.ceil instead to give integer results.
• The GetBitmapTextSize function has a new boolean parameter updateOrigin, which will adjust the origin of the parent BitmapText if set, based on the new bounds calculations.
• BitmapText.preDestroy is a new method that will tidy-up all of the BitmapText data during object destruction.
• BitmapText.dropShadowX is a new property that controls the horizontal offset of the drop shadow on the Bitmap Text.
• BitmapText.dropShadowY is a new property that controls the vertical offset of the drop shadow on the Bitmap Text.
• BitmapText.dropShadowColor is a new property that sets the color of the Bitmap Text drop shadow.
• BitmapText.dropShadowAlpha is a new property that sets the alpha of the Bitmap Text drop shadow.
• BatchChar is a new internal private function for batching a single character of a Bitmap Text to the pipeline.
• If you give an invalid Bitmap Font key, the Bitmap Text object will now issue a console.warn.
• Setting the color value in the DynamicBitmapText.setDisplayCallback would inverse the red and blue channels if the color was not properly encoded for WebGL. It is now encoded automatically, meaning you can pass normal hex values as the colors in the display callback. Fix #5225 (thanks @teebarjunk)
• If you apply setSize to the Dynamic BitmapText the scissor is now calculated based on the parent transforms, not just the local ones, meaning you can crop Bitmap Text objects that exist within Containers. Fix #4653 (thanks @lgibson02)
• ParseXMLBitmapFont has a new optional parameter texture. If defined, this Texture is populated with Frame data, one frame per glyph. This happens automatically when loading Bitmap Text data in Phaser.

Update List Changes

The way in which Game Objects add themselves to the Scene Update List has changed. Instead of being added by the Factory methods, they will now add and remove themselves based on the new ADDED_TO_SCENE and REMOVED_FROM_SCENE events. This means, you can now add Sprites directly to a Container, or Group, and they'll animate properly without first having to be part of the Display List. The full set of changes and new features relating to this follow:

• GameObjects.Events.ADDED_TO_SCENE is a new event, emitted by a Game Object, when it is added to a Scene, or a Container that is part of the Scene.
• GameObjects.Events.REMOVED_FROM_SCENE is a new event, emitted by a Game Object, when it is removed from a Scene, or a Container that is part of the Scene.
• Scenes.Events.ADDED_TO_SCENE is a new event, emitted by a Scene, when a new Game Object is added to the display list in the Scene, or a Container that is on the display list.
• Scenes.Events.REMOVED_FROM_SCENE is a new event, emitted by a Scene, when it a Game Object is removed from the display list in the Scene, or a Container that is on the display list.
• GameObject.addedToScene is a new method that custom Game Objects can use to perform additional set-up when a Game Object is added to a Scene. For example, Sprite uses this to add itself to the Update List.
• GameObject.removedFromScene is a new method that custom Game Objects can use to perform additional tear-down when a Game Object is removed from a Scene. For example, Sprite uses this to remove themselves from the Update List.
• Game Objects no longer automatically remove themselves from the Update List during preDestroy. This should be handled directly in the removedFromScene method now.
• The Container will now test to see if any Game Object added to it is already on the display list, or not, and emit its ADDED and REMOVED events accordingly. Fix #5267 #3876 (thanks @halgorithm @mbpictures)
• DisplayList.events is a new property that references the Scene's Event Emitter. This is now used internally.
• DisplayList.addChildCallback is a new method that overrides the List callback and fires the new ADDED events.
• DisplayList.removeChildCallback is a new method that overrides the List callback and fires the new REMOVED events.
• GameObjectCreator.events is a new property that references the Scene's Event Emitter. This is now used internally.
• GameObjectFactory.events is a new property that references the Scene's Event Emitter. This is now used internally.
• ProcessQueue.checkQueue is a new boolean property that will make sure only unique objects are added to the Process Queue.
• The Update List now uses the new checkQueue property to ensure no duplicate objects are on the active list.
• DOMElementFactory, ExternFactory, ParticleManagerFactor, RopeFactory and SpriteFactory all no longer add the objects to the Update List, this is now handled by the ADDED events instead.
• Sprite, Rope, ParticleEmitterManager, Extern and DOMElement now all override the addedToScene and removedFromScene callbacks to handle further set-up tasks.

Spine Plugin Updates

• The Spine Runtimes have been updated to 3.8.95, which are the most recent non-beta versions. Please note, you will need to re-export your animations if you're working in a version of Spine lower than 3.8.20.
• SpineContainer is a new Game Object available via this.add.spineContainer to which you can add Spine Game Objects only. It uses a special rendering function to retain batching, even across multiple container or Spine Game Object instances, resulting in dramatically improved performance over using regular Containers.
• A Spine Game Object with setVisible(false) will no longer still cause internal gl commands and is now properly skipped, retaining any current batch in the process. Fix #5174 (thanks @Kitsee)
• The Spine Game Object WebGL Renderer will no longer clear the type if invisible and will only end the batch if the next type doesn't match.
• The Spine Game Object WebGL Renderer will no longer rebind the pipeline if it was the final object on the display list, saving lots of gl commands.
• The Webpack build scripts have all been updated for Webpack 4.44.x. Fix #5243 (thanks @RollinSafary)
• There is a new npm script npm run plugin.spine.runtimes which will build all of the Spine runtimes, for ingestion by the plugin. Note: You will need to check-out the Esoteric Spine Runtimes repo into plugins/spine/ in order for this to work.
• Spine Game Objects can now be rendered to Render Textures. Fix #5184 (thanks @Kitsee)
• Using > 128 Spine objects in a Container would cause a WebGL: INVALID_OPERATION: vertexAttribPointer: no ARRAY_BUFFER is bound and offset is non-zero error if you added any subsequent Spine objects to the Scene. There is now no limit. Fix #5246 (thanks @d7561985)
• The Spine Plugin will now work in HEADLESS mode without crashing. Fix #4988 (thanks @raimon-segura)
• Spine Game Objects now use -1 as their default blend mode, which means 'skip setting it'.
• The Spine TypeScript defs have been updated for the latest version of the plugin and to add SpineContainers.
• The SpineGameObject.setAnimation method will now use the trackIndex parameter if ignoreIfPlaying is set and run the check against this track index. Fix #4842 (thanks @vinerz)
• The SpineFile will no longer throw a warning if adding a texture into the Texture Manager that already exists. This allows you to have multiple Spine JSON use the same texture file, however, it also means you now get no warning if you accidentally load a texture that exists, so be careful with your keys! Fix #4947 (thanks @Nomy1)
• The Spine Plugin destroy method will now no longer remove the Game Objects from the Game Object Factory, or dispose of the Scene Renderer. This means when a Scene is destroyed, it will keep the Game Objects in the factory for other Scene's to use. Fix #5279 (thanks @Racoonacoon)
• SpinePlugin.gameDestroy is a new method that is called if the Game instance emits a destroy event. It removes the Spine Game Objects from the factory and disposes of the Spine scene renderer.

Animation API - New Features and Updates

If you use Animations in your game, please read the following important API changes in 3.50:

The Animation API has had a significant overhaul to improve playback handling. Instead of just playing an animation based on its global key, you can now supply a new PlayAnimationConfig object instead, which allows you to override any of the default animation settings, such as duration, delay and yoyo (see below for the full list). This means you no longer have to create lots of duplicate animations just to change properties such as duration, and can now set them dynamically at run-time as well.

• The Animation class no longer extends EventEmitter, as it no longer emits any events directly. This means you cannot now listen for events directly from an Animation instance. All of the events are now dispatched by the Game Objects instead.
• All of the SPRITE_ANIMATION_KEY events have been removed. Instead, please use the new events which all carry the frameKey parameter, which can be used to handle frame specific events. The only exception to this is ANIMATION_COMPLETE_KEY, which is a key specific version of the completion event.
• ANIMATION_UPDATE_EVENT is a new event that is emitted from a Sprite when an animation updates, i.e. its frame changes.
• ANIMATION_STOP_EVENT is a new event that is emitted from a Sprite when its current animation is stopped. This can happen if any of the stop methods are called, or a new animation is played prior to this one reaching completion. Fix #4894 (thanks @scott20145)
• The Game Object Component.Animation component has been renamed to AnimationState and has moved namespace. It's now in Phaser.Animations instead of GameObjects.Components to help differentiate it from the Animation class when browsing the documentation.
• The play, playReverse, playAfterDelay, playAfterRepeat and chain Sprite and Animation Component methods can now all take a Phaser.Types.Animations.PlayAnimationConfig configuration object, as well as a string, as the key parameter. This allows you to override any default animation setting with those defined in the config, giving you far greater control over animations on a Game Object level, without needing to globally duplicate them.
• AnimationState.create is a new method that allows you to create animations directly on a Sprite. These are not global and never enter the Animation Manager, instead risiding within the Sprite itself. This allows you to use the same keys across both local and global animations and set-up Sprite specific local animations.
• All playback methods: play, playReverse, playAfterDelay and playAfterRepeat will now check to see if the given animation key exists locally on the Sprite first. If it does, it's used, otherwise it then checks the global Animation Manager for the key instead.
• AnimationState.skipMissedFrames is now used when playing an animation, allowing you to create animations that run at frame rates far exceeding the refresh rate, or that will update to the correct frame should the game lag. Feature #4232 (thanks @colorcube)
• AnimationManager.addMix is a new method that allows you to create mixes between two animations. Mixing allows you to specify a unique delay between a pairing of animations. When playing Animation A on a Game Object, if you then play Animation B, and a mix exists, it will wait for the specified delay to be over before playing Animation B. This allows you to customise smoothing between different types of animation, such as blending between an idle and a walk state, or a running and a firing state.
• AnimationManager.getMix is a new method that will return the mix duration between the two given animations.
• AnimationManager.removeMix is a new method that will remove the mixture between either two animations, or all mixtures for the given animation.
• AnimationState.remove is a new method that will remove a locally stored Animation instance from a Sprite.
• AnimationState.get is a new method that will return a locally stored Animation instance from the Sprite.
• AnimationState.exists is a new method that will check if a locally stored Animation exists on the Sprite.
• The internal AnimationState.remove method has been renamed to globalRemove.
• AnimationState.textureManager is a new property that references the global Texture Manager.
• AnimationState.anims is a new property that contains locally created Animations in a Custom Map.
• AnimationState.play and Sprite.play no longer accept a startFrame parameter. Please set it via the PlayAnimationConfig instead.
• AnimationState.playReverse and Sprite.playReverse no longer accept a startFrame parameter. Please set it via the PlayAnimationConfig instead.
• The AnimationState.delayedPlay method has been renamed to playAfterDelay. The parameter order has also changed, so the key now comes first instead of the duration.
• The AnimationState.stopOnRepeat method has been renamed to stopAfterRepeat
• The AnimationState.getCurrentKey method has been renamed to getName.
• AnimationState.getFrameName is a new method that will return the key of the current Animation Frame, if an animation has been loaded.
• AnimationState.playAfterDelay and Sprite.playAfterDelay are new methods that will play the given animation after the delay in ms expires.
• AnimationState.playAfterRepeat and Sprite.playAfterRepeat are new methods that will play the given animation after the current animation finishes repeating. You can also specify the number of repeats allowed left to run.
• The AnimationState.chain method is now available on the Sprite class.
• The AnimationState.stopAfterDelay method is now available on the Sprite class.
• The AnimationState.stopAfterRepeat method is now available on the Sprite class.
• The AnimationState.stopOnFrame method is now available on the Sprite class.
• AnimationManager.createFromAseprite is a new method that allows you to use animations created in the Aseprite editor directly in Phaser. Please see the comprehensive documentation for this method for full details on how to do this.
• AnimationState now handles all of the loading of the animation. It no longer has to make calls out to the Animation Manager or Animation instance itself and will load the animation data directly, replacing as required from the optional PlayAnimationConfig. This improves performance and massively reduces CPU calls in animation heavy games.
• The PlayAnimationConfig.frameRate property lets you optionally override the animation frame rate.
• The PlayAnimationConfig.duration property lets you optionally override the animation duration.
• The PlayAnimationConfig.delay property lets you optionally override the animation delay.
• The PlayAnimationConfig.repeat property lets you optionally override the animation repeat counter.
• The PlayAnimationConfig.repeatDelay property lets you optionally override the animation repeat delay value.
• The PlayAnimationConfig.yoyo property lets you optionally override the animation yoyo boolean.
• The PlayAnimationConfig.showOnStart property lets you optionally override the animation show on start value.
• The PlayAnimationConfig.hideOnComplete property lets you optionally override the animation hide on complete value.
• The PlayAnimationConfig.startFrame property lets you optionally set the animation frame to start on.
• The PlayAnimationConfig.timeScale property lets you optionally set the animation time scale factor.
• AnimationState.delayCounter is a new property that allows you to control the delay before an animation will start playing. Only once this delay has expired, will the animation START events fire. Fix #4426 (thanks @bdaenen)
• AnimationState.hasStarted is a new boolean property that allows you to tell if the current animation has started playing, or is still waiting for a delay to expire.
• AnimationState.showOnStart is a new boolean property that controls if the Game Object should have setVisible(true) called on it when the animation starts.
• AnimationState.hideOnComplete is a new boolean property that controls if the Game Object should have setVisible(false) called on it when the animation completes.
• The AnimationState.chain method docs said it would remove all pending animations if called with no parameters. However, it didn't - and now does!
• The AnimationState.setDelay method has been removed. It never actually worked and you can now perform the same thing by calling either playAfterDelay or setting the delay property in the play config.
• The AnimationState.getDelay method has been removed. You can now read the delay property directly.
• The AnimationState.setRepeat method has been removed. You can achieve the same thing by setting the repeat property in the play config, or adjusting the public repeatCounter property if the animation has started.

• The Animation.load method has been removed as it's no longer required.
• The Animation.setFrame method has been removed as it's no longer required.

Mesh Game Object - New Features, Updates and API Changes

The Mesh Game Object has been rewritten in v3.50 with a lot of changes to make it more useful and able to handle 3D objects:

• GameObject.Vertex is a new micro class that encapsulates all of the data required for a single vertex, such as position, uv, color and alpha. This class is now created internally by the Mesh Game Object.
• GameObject.Face is a new micro class that consists of references to the three Vertex instances that construct the single Face.
• The Mesh constructor and MeshFactory signatures have changed to scene, x, y, texture, frame, vertices, uvs, indicies, colors, alphas. Note the way the Texture and Frame parameters now comes first. indicies is a new parameter added to the list. It allows you to provide indexed vertex data to create the Mesh from, where the indicies array holds the vertex index information. The final list of vertices is built from this index along with the provided vertices and uvs arrays. The indicies array is optional. If your data is not indexed, then simply pass null or an empty array for this parameter.
• The Mesh Game Object now extends the SingleAlpha component and the alpha value is factored into the final alpha value per vertex during rendering. This means you can now set the whole alpha across the Mesh using the standard setAlpha methods. But, if you wish to, you can still control the alpha on a per-vertex basis as well.
• The Mesh Game Object now has the Animation State Component. This allows you to create and play animations across the texture of a Mesh, something that previously wasn't possible. As a result, the Mesh now adds itself to the Update List when added to a Scene.
• Geom.ParseObj is a new function that will parse a triangulated Wavefront OBJ file into model data that can be consumed by the Mesh Game Object.
• Loader.OBJFile is a new File Loader type that can load triangulated Wavefront OBJ files, which are then parsed and stored in the OBJ Cache.
• Mesh.hideCCW is a new boolean property that, when enabled, tells a Face to not render if it isn't counter-clockwise. You can use this to hide backward facing Faces.
• Mesh.addOBJ is a new method that will add the model data from a loaded Wavefront OBJ file to a Mesh. You load it via the new OBJFile with a this.load.obj call, then you can use the key with the addOBJ method. This method also takes an optional scale and position parameters to control placement of the created model within the Mesh.
• Mesh.addModel is a new method that will add the model data to a Mesh. You can prepare the model data yourself, pull it in from a server, or get it by calling Geom.ParseObj, or a similar custom function. This method also takes an optional scale and position parameters to control placement of the created model within the Mesh.
• Mesh.rotateX is a new method that will rotate all vertices of the Mesh around the x axis, by the amount given. It then depth sorts the faces.
• Mesh.rotateY is a new method that will rotate all vertices of the Mesh around the y axis, by the amount given. It then depth sorts the faces.
• Mesh.rotateZ is a new method that will rotate all vertices of the Mesh around the z axis, by the amount given. It then depth sorts the faces.
• Mesh.depthSort is a new method that will run a depth sort across all Faces in the Mesh by sorting them on their average depth.
• Mesh.addVertex is a new method that allows you to add a new single Vertex into the Mesh.
• Mesh.addFace is a new method that allows you to add a new Face into the Mesh. A Face must consist of 3 Vertex instances.
• Mesh.addVertices is a new method that allows you to add vertices to a Mesh Game Object based on the given parameters. This allows you to modify a mesh post-creation, or populate it with data at a later stage.
• Mesh.getFaceCount new is a new method that will return the total number of Faces in the Mesh.
• Mesh.getVertexCount new is a new method that will return the total number of Vertices in the Mesh.
• Mesh.getFace new is a new method that will return a Face instance from the Mesh based on the given index.
• Mesh.getFaceAt new is a new method that will return an array of Face instances from the Mesh based on the given position. The position is checked against each Face, translated through the optional Camera and Mesh matrix. If more than one Face intersects, they will all be returned but the array will be depth sorted first, so the first element will be that closest to the camera.
• Mesh.vertices is now an array of GameObject.Vertex instances, not a Float32Array.
• Mesh.faces is a new array of GameObject.Face instances, which is populated during a call to methods like addVertices or addModel.
• Mesh.clearVertices is a new method that will destroy all Faces and Vertices and clear the Mesh.
• Mesh.setDebug is a new method that allows you to render a debug visualisation of the Mesh vertices to a Graphics Game Object. You can provide your own Graphics instance and optionally callback that is invoked during rendering. This allows you to easily visualise the vertices of your Mesh to help debug UV mapping.
• The Mesh now renders by iterating through the Faces array, not the vertices. This allows you to use Array methods such as BringToTop to reposition a Face, thus changing the drawing order without having to repopulate all of the vertices. Or, for a 3D model, you can now depth sort the Faces.
• The Mesh renderer will now check to see if the pipeline capacity has been exceeded for every Face added, allowing you to use Meshes with vertex counts that exceed the pipeline capacity without causing runtime errors.
• You can now supply just a single numerical value as the colors parameter in the constructor, factory method and addVertices method. If a number, instead of an array, it will be used as the color for all vertices created.
• You can now supply just a single numerical value as the alphas parameter in the constructor, factory method and addVertices method. If a number, instead of an array, it will be used as the alpha for all vertices created.
• Mesh.debugGraphic is a new property that holds the debug Graphics instance reference.
• Mesh.debugCallback is a new property that holds the debug render callback.
• Mesh.renderDebugVerts is a new method that acts as the default render callback for setDebug if none is provided.
• Mesh.preDestroy is a new method that will clean-up the Mesh arrays and debug references on destruction.
• The Mesh.uv array has been removed. All UV data is now bound in the Vertex instances.
• The Mesh.colors array has been removed. All color data is now bound in the Vertex instances.
• The Mesh.alphas array has been removed. All color data is now bound in the Vertex instances.
• The Mesh.tintFill property is now a boolean and defaults to false.

Input / Mouse Updates and API Changes

• ScaleManager.refresh is now called when the Game.READY event fires. This fixes a bug where the Scale Manager would have the incorrect canvas bounds, because they were calculated before a previous canvas was removed from the DOM. Fix #4862 (thanks @dranitski)
• The Game Config property inputMouseCapture has been removed, as this is now split into 3 new config options:
• inputMousePreventDefaultDown is a new config option that allows you to control preventDefault calls specifically on mouse down events. Set it via input.mouse.preventDefaultDown in the Game Config. It defaults to true, the same as the previous capture property did.
• inputMousePreventDefaultUp is a new config option that allows you to control preventDefault calls specifically on mouse up events. Set it via input.mouse.preventDefaultUp in the Game Config. It defaults to true, the same as the previous capture property did.
• inputMousePreventDefaultMove is a new config option that allows you to control preventDefault calls specifically on mouse move events. Set it via input.mouse.preventDefaultMove in the Game Config. It defaults to true, the same as the previous capture property did.
• The MouseManager.capture property has been removed, as this is now split into 3 new config options (see below)
• MouseManager.preventDefaultDown is a new boolean property, set via the inputMousePreventDefaultDown config option that allows you to toggle capture of mouse down events at runtime.
• MouseManager.preventDefaultUp is a new boolean property, set via the inputMousePreventDefaultUp config option that allows you to toggle capture of mouse up events at runtime.
• MouseManager.preventDefaultMove is a new boolean property, set via the inputMousePreventDefaultMove config option that allows you to toggle capture of mouse move events at runtime.
• In the MouseManager the up, down and move events are no longer set as being passive if captured. Over, Out, Wheel and the Window level Down and Up events are always flagged as being passive.
• The GamepadPlugin will now call refreshPads as part of its start process. This allows you to use Gamepads across multiple Scenes, without having to wait for a connected event from each one of them. If you've already had a connected event in a previous Scene, you can now just read the pads directly via this.input.gamepad.pad1 and similar. Fix #4890 (thanks @Sytten)
• Shutting down the Gamepad plugin (such as when sleeping a Scene) no longer calls GamepadPlugin.disconnectAll, but destroying it does.
• Gamepad._created is a new private internal property that keeps track of when the instance was created. This is compared to the navigator timestamp in the update loop to avoid event spamming. Fix #4890.

Tint Updates and Shader Changes

Phaser has had the ability to apply an additive tint to a Game Object since the beginning, and gained 'filled tints', with and without texture alpha, in v3.11. While this was handy, it introduced a 3-way if-else condition to the shaders to handle the different modes. Plus, setting tint colors was also generating rgb order Float32 color values for each Game Object, making reading those colors back again difficult (as they'd return in BGR order).

This has all changed in 3.50, as outlined below. Tint values are now used directly in the shader and don't pass through a color conversion function first. Lots of private properties have been removed and the shaders no longer have a 3-way if-else block. All of this means improved performance and a slight reduction in memory overhead.

• Tint.tintTopLeft is now a normal property in RGB order, not a setter, and no longer passes through the GetColorFromValue function. This directly replaces the private property _tintTL which has now been removed.
• Tint.tintTopRight is now a normal property in RGB order, not a setter, and no longer passes through the GetColorFromValue function. This directly replaces the private property _tintTR which has now been removed.
• Tint.tintBottomLeft is now a normal property in RGB order, not a setter, and no longer passes through the GetColorFromValue function. This directly replaces the private property _tintBL which has now been removed.
• Tint.tintBottomRight is now a normal property in RGB order, not a setter, and no longer passes through the GetColorFromValue function. This directly replaces the private property _tintBR which has now been removed.
• The property Tint._isTinted has been removed as it's no longer required.
• The Single.frag, Light.frag and Multi.frag shaders have all been updated so they now read the color value as outTint.bgr instead of outTint.rgb. This allows the colors to remain in RGB order within the Tint component.
• The Single.frag, Light.frag and Multi.frag shaders have all been updated so they no longer have a 3-way check on the outTintEffect value.
• The Multi Pipeline, Bitmap Text, Render Texture, Text, TileSprite and Camera now all read the tint values from the public properties instead of the private _tintTL etc ones. They also now set the tintEffect value directly from the tintFill property, removing another conditional check.
• The function GetColorFromValue has been removed as it's no longer used internally.
• The Rope.tintFill property is now a boolean, not an integer, and can no longer take 2 as a value for a complete fill. Instead, you should provide a solid color texture with no alpha.
• As a result of the change to the shader, all uses of the WebGL Util function getTintAppendFloatAlphaAndSwap have been replaced with getTintAppendFloatAlpha instead.
• As a result of the change to the shader, the Multi Pipeline now uses the WebGLRenderer.whiteTexture and tintEffect mode of 1 by default, instead of mode 2 (which has been removed) and a transparent texture. This ensures Graphics and Shapes objects still render correctly under the new smaller shader code.
• WebGLRenderer.whiteTexture is a new property that is a reference to a pure white 4x4 texture that is created during Boot by the Texture Manager. The Multi Pipeline uses this internally for all Graphic, Shape and fill rendering.
• The TextureManager now generates a new texture with the key __WHITE durings its boot process. This is a pure white 4x4 texture used by the Graphics pipelines.
• Config.images.white is a new Game Config property that specifies the 4x4 white PNG texture used by Graphics rendering. You can override this via the config, but only do so if needed.

Removal of 'resolution' property from across the API

For legacy reasons, Phaser 3 has never properly supported HighDPI devices. It will render happily to them of course, but wouldn't let you set a 'resolution' for the Canvas beyond 1. Earlier versions of 3.x had a resolution property in the Game Config, but it was never fully implemented (for example, it would break zooming cameras). When the Scale Manager was introduced in v3.16 we forced the resolution to be 1 to avoid it breaking anything else internally.

For a long time, the 'resolution' property has been present - taunting developers and confusing new comers. In this release we have finally gone through and removed all references to it. The Game Config option is now gone, it's removed from the Scale Manager, Base Camera and everywhere else where it matters. As much as we would have liked to implement the feature, we've spent too long without it, and things have been built around the assumption it isn't present. The API just wouldn't cope with having it shoe-horned in at this stage. As frustrating as this is, it's even more annoying to just leave the property there confusing people and wasting CPU cycles. Phaser 4 has been built with HighDPI screens in mind from the very start, but it's too late for v3. The following changes are a result of this removal:

• The Phaser.Scale.Events#RESIZE event no longer sends the resolution as a parameter.
• The BaseCamera.resolution property has been removed.
• The internal private BaseCamera._cx, _cy, _cw and _ch properties has been removed.
• The BaseCamera.preRender method no longer receives or uses the resolution parameter.
• The Camera.preRender method no longer receives or uses the resolution parameter.
• The CameraManager.onResize method no longer receives or uses the resolution parameter.
• The Core.Config.resolution property has been removed.
• The TextStyle.resolution property is no longer read from the Game Config. You can still set it via the Text Style config to a value other than 1, but it will default to this now.
• The CanvasRenderer no longer reads or uses the Game Config resolution property.
• The PipelineManager.resize method along with WebGLPipeline.resize and anything else that extends them no longer receives or uses the resolution parameter.
• The WebGLRenderer.resize and onResize methods no longer receives or uses the resolution parameter.
• The ScaleManager.resolution property has been removed and all internal use of it.

Removed 'interpolationPercentage' parameter from all render functions

Since v3.0.0 the Game Object render functions have received a parameter called interpolationPercentage that was never used. The renderers do not calculate this value and no Game Objects apply it, so for the sake of clairty, reducing code and removing complexity from the API it has been removed from every single function that either sent or expected the parameter. This touches every single Game Object and changes the parameter order as a result, so please be aware of this if you have your own custom Game Objects that implement their own render methods. In terms of surface API changes, you shouldn't notice anything at all from this removal.

New Features

• Geom.Intersects.GetLineToLine is a new function that will return a Vector3 containing the point of intersection between 2 line segments, with the z property holding the distance value.
• Geom.Intersects.GetLineToPolygon is a new function that checks for the closest point of intersection between a line segment and an array of polygons.
• Geom.Intersects.GetLineToPoints is a new function that checks for the closest point of intersection between a line segment and an array of points, where each pair of points form a line segment.
• Geom.Intersects.GetRaysFromPointToPolygon is a new function that emits rays out from the given point and detects for intersection against all given polygons, returning the points of intersection in the results array.
• Geom.Polygon.Translate is a new function that allows you to translate all the points of a polygon by the given values.
• Geom.Polygon.Simplify is a new function that takes a polygon and simplifies the points by running them through a combination of Douglas-Peucker and Radial Distance algorithms, potentially dramatically reducing the number of points while retaining its shape.
• WebGLRenderer.setInt1iv will allow you to look-up and set a 1iv uniform on the given shader.
• Phaser.Types.Math.Vector3Like is a new data type representing as Vector 3 like object.
• Phaser.Types.Math.Vector4Like is a new data type representing as Vector 4 like object.
• Transform.getLocalPoint is a new method, available on all Game Objects, that takes an x / y pair and translates them into the local space of the Game Object, factoring in parent transforms and display origins.
• The KeyboardPlugin will now track the key code and timestamp of the previous key pressed and compare it to the current event. If they match, it will skip the event. On some systems, if you were to type quickly, you would sometimes get duplicate key events firing (the exact same event firing more than once). This is now prevented from happening.
• Display.Color.GetColorFromValue is a new function that will take a hex color value and return it as an integer, for use in WebGL. This is now used internally by the Tint component and other classes.
• Utils.String.RemoveAt is a new function that will remove a character from the given index in a string and return the new string.
• Frame.setUVs is a new method that allows you to directly set the canvas and UV data for a frame. Use this if you need to override the values set automatically during frame creation.
• TweenManager.getTweensOf has a new parameter includePending. If set, it will also check the pending tweens for the given targets and return those in the results as well. Fix #5260 (thanks @pcharest2000)
• WebGLPipeline.hasBooted is a new boolean property that tracks if the pipeline has been booted or not, which is now far more important in 3.5 than in previous versions. This is checked in the WebGLRenderer.addPipeline method, and if not set, the pipeline is booted. Fix #5251 #5255 (thanks @telinc1 @rexrainbow)
• The WebGL Renderer will now add the pipelines during the boot method, instead of init.
• You can now use this.renderer from within a Scene, as it's now a Scene-level property and part of the Injection Map.
• Clock.addEvent can now take an existing TimerEvent object, as well as a config object. If a TimerEvent is given it will be removed from the Clock, reset and then added. This allows you to pool TimerEvents rather than constantly create and delete them. Fix #4115 (thanks @jcyuan)
• Clock.removeEvent is a new method that allows you to remove a TimerEvent, or an array of them, from all internal lists of the current Clock.
• Group.getMatching is a new method that will return any members of the Group that match the given criteria, such as getMatching('visible', true) (thanks @atursams)
• ArcadePhysics.disableUpdate is a new method that will prevent the Arcade Physics World update method from being called when the Scene updates. By disabling it, you're free to call the update method yourself, passing in your own delta and time values.
• ArcadePhysics.enableUpdate is a new method that will make the Arcade Physics World update in time with the Scene update. This is the default, so only call this if you have specifically disabled it previously.
• ArcadeWorldConfig.customUpdate is a new boolean property you can set in the Arcade Physics config object, either in the Scene or in the Game Config. If true the World update will never be called, allowing you to call it yourself from your own component. Close #5190 (thanks @cfortuner)
• Utils.Array.SortByDigits is a new function that takes the given array of strings and runs a numeric sort on it, ignoring any non-digits.
• GroupCreateConfig, which is used when calling Group.createMultiple or Group.createFromConfig, can now accept the following new properties: setOrigin: { x, y, stepX, stepY } which are applied to the items created by the Group.
• Transform.copyPosition is a new method that will copy the position from the given object to the Game Object (thanks @samme)
• The Text.MeasureText function, which is used to calculate the ascent and descent of Text Game Objects whenever the style, or font size, is changed, has been updated to use the new actualBoundingBoxAscent functions present in modern browsers. This allows for significantly faster ascent calculations than previously. Older browsers, such as IE, will still fall back (thanks @rexrainbow)
• GameObjects.GetCalcMatrix is a new function that is used to calculate the transformed Game Object matrix, based on the given Game Object, Camera and Parent. This function is now used by the following Game Objects: BitmapText (Static and Dynamic), Graphics, Extern, Mesh, Rope, Shader, Arc, Curve, Ellipse, Grid, IsoBox, IsoTriangle, Line, Polygon, Rectangle, Star and Triangle. This dramatically reduces the amount of duplicate code across the API.
• Utils.Array.Matrix.Translate is a new function that will translate an Array Matrix by horizontally and vertically by the given amounts.

Updates and API Changes

• Earcut, used for polygon triangulation, has been updated from 2.1.4 to 2.2.2.
• Earcut has now been exposed and is available via Geom.Polygon.Earcut and is fully documented.
• Config.batchSize has been increased from 2000 to 4096.
• Removed the Deferred Diffuse fragment and vertex shaders from the project, as they're not used.
• StaticTilemapLayer.upload will now set the vertex attributes and buffer the data, and handles internal checks more efficiently.
• StaticTilemapLayer now includes the ModelViewProjection mixin, so it doesn't need to modify the pipeline during rendering.
• WebGLRenderer.textureFlush is a new property that keeps track of the total texture flushes per frame.
• The TextureTintStripPipeline now extends TextureTintPipeline and just changes the topolgy, vastly reducing the filesize.
• TransformMatrix.getXRound is a new method that will return the X component, optionally passed via Math.round.
• TransformMatrix.getYRound is a new method that will return the Y component, optionally passed via Math.round.
• The KeyboardPlugin no longer emits keydown_ events. These were replaced with keydown- events in v3.15. The previous event string was deprecated in v3.20.
• The KeyboardPlugin no longer emits keyup_ events. These were replaced with keyup- events in v3.15. The previous event string was deprecated in v3.20.
• The ScaleManager.updateBounds method is now called every time the browser fires a 'resize' or 'orientationchange' event. This will update the offset of the canvas element Phaser is rendering to, which is responsible for keeping input positions correct. However, if you change the canvas position, or visibility, via any other method (i.e. via an Angular route) you should call the updateBounds method directly, yourself.
• The constant Phaser.Renderer.WebGL.BYTE value has been removed as it wasn't used internally.
• The constant Phaser.Renderer.WebGL.SHORT value has been removed as it wasn't used internally.
• The constant Phaser.Renderer.WebGL.UNSIGNED_BYTE value has been removed as it wasn't used internally.
• The constant Phaser.Renderer.WebGL.UNSIGNED_SHORT value has been removed as it wasn't used internally.
• The constant Phaser.Renderer.WebGL.FLOAT value has been removed as it wasn't used internally.
• global.Phaser = Phaser has been removed, as it's no longer required by the UMD loader, which should make importing in Angular 10 easier. Fix #5212 (thanks @blackyale)
• Pointer.downTime now stores the event timestamp of when the first button on the input device was pressed down, not just when button 1 was pressed down.
• Pointer.upTime now stores the event timestamp of when the final depressed button on the input device was released, not just when button 1 was released.
• The Pointer.getDuration method now uses the new Pointer downTime and upTime values, meaning it will accurately report the duration of when any button is being held down, not just the primary one. Fix #5112 (thanks @veleek)
• The BaseShader default vertex shader now includes the outTexCoord vec2 varying, mapped to be the same as that found in the pipeline shaders. Fix #5120 (@pavel-shirobok)
• When using the GameObjectCreator for Containers you can now specify the children property in the configuration object.
• WebGLRenderer.finalType is a new boolean property that signifies if the current Game Object being rendered is the final one in the list.
• The WebGLRenderer.updateCanvasTexture method will now set gl.UNPACK_PREMULTIPLY_ALPHA_WEBGL to true, which should stop issues where you update a Text Game Object, having added a Render Texture or Spine Game Object to the Scene after it, which switches the PMA setting. Fix #5064 #5155 (thanks @hugoruscitti @immangrove-supertree)
• Textures.Parsers.JSONHash will now perform a hasOwnProperty check when iterating the frames, skipping anything that isn't a direct property. This should allow you to use generated atlas data that comes from JSON.parse. Fix #4768 (thanks @RollinSafary)
• The Camera3D Plugin has been rebuilt for Phaser 3.50 and the webpack config updated. This plugin is now considered deprecated and will not be updated beyond this release.
• Tween.seek will no longer issue a console warning for 'Tween.seek duration too long', it's now up to you to check on the performance of tween seeking.
• WebGLRenderer.previousPipeline is a new property that is set during a call to clearPipeline and used during calls to rebindPipeline, allowing the renderer to rebind any previous pipeline, not just the Multi Pipeline.
• The WebGLRenderer.rebindPipeline method has been changed slightly. Previously, you had to specify the pipelineInstance, but this is now optional. If you don't, it will use the new previousPipeline property instead. If not set, or none given, it will now return without throwing gl errors as well.
• If inputWindowEvents is set in the Game Config, then the MouseManager will now listen for the events on window.top instead of just window, which should help in situations where the pointer is released outside of an embedded iframe. Fix #4824 (thanks @rexrainbow)
• Types.GameObjects.Text.GetTextSizeObject is a new type def for the GetTextSize function results.
• The Arcade.Body.resetFlags method has a new optional boolean parameter clear. If set, it clears the wasTouching flags on the Body. This happens automatically when Body.reset is called. Previous to this, the flags were not reset until the next physics step (thanks @samme)
• Utils.Array.StableSort has been recoded. It's now based on Two-Screens stable sort 0.1.8 and has been updated to fit into Phaser better and no longer create any window bound objects. The inplace function has been removed, just call StableSort(array) directly now. All classes that used StableSort.inplace have been updated to call it directly.
• If a Scene is paused, or sent to sleep, it will automatically call Keyboard.resetKeys. This means that if you hold a key down, then sleep or pause a Scene, then release the key and resume or wake the Scene, it will no longer think it is still being held down (thanks @samme)
• Actions.setOrigin will now call updateDisplayOrigin on the items array, otherwise the effects can't be seen when rendering.
• You can now set the ArcadeWorld.fixedStep property via the ArcadeWorldConfig object (thanks @samme)
• Utils.Array.NumerArray can now accept the start and end parameters in reverse order, i.e. 10, 1 will generate a number array running from 10 to 1. Internally it has also been optimized to skip string based returns.
• DataManager.Events.DESTROY is a new event that the Data Manager will listen for from its parent and then call its own destroy method when received.

Bug Fixes

• RenderTexture.resize (which is called from setSize) wouldn't correctly set the TextureSource.glTexture property, leading to bindTexture: attempt to use a deleted object errors under WebGL.
• RenderTexture.fill would fail to fill the correct area under WebGL if the RenderTexture wasn't the same size as the Canvas. It now fills the given region properly.
• The MatterAttractors plugin, which enables attractors between bodies, has been fixed. The original plugin only worked if the body with the attractor was first in the world bodies list. It can now attract any body, no matter where in the world list it is. Fix #5160 (thanks @strahius)
• The KeyboardManager and KeyboardPlugin were both still checking for the InputManager.useQueue property, which was removed several versions ago.
• In Arcade Physics, Dynamic bodies would no longer hit walls when riding on horizontally moving platforms. The horizontal (and vertical) friction is now re-applied correctly in these edge-cases. Fix #5210 (thanks @Dercetech @samme)
• Calling Rectangle.setSize() wouldn't change the underlying geometry of the Shape Game Object, causing any stroke to be incorrectly rendered after a size change.
• The ProcessQueue was emitting the wrong events internally. It now emits 'add' and 'remove' correctly (thanks @halilcakar)
• The GridAlign action didn't work if only the height parameter was set. Fix #5019 (thanks @halilcakar)
• The Color.HSVToRGB function has been rewritten to use the HSL and HSV formula from Wikipedia, giving much better results. Fix #5089 (thanks @DiamondeX)
• Previously, the easeParams array within a Tweens props object, or a multi-object tween, were ignored and it was only used if set on the root Tween object. It will now work correctly set at any depth. Fix #4292 (thanks @willblackmore)
• When using Camera.setRenderToTexture its zoom and rotation values would be applied twice. Fix #4221 #4924 #4713 (thanks @wayfu @DanMcgraw @pavel-shirobok)
• GameObjects.Shape.Grid would render a white fill even if you passed undefined as the fill color in the constructor. It now doesn't render cells if no fill color is given.
• The onMouse events in the Input Manager didn't reset the activePointer property to the mouse, meaning on dual-input systems such as Touch Screen devices, the active pointer would become locked to whichever input method was used first. Fix #4615 #5232 (thanks @mmolina01 @JstnPwll @Legomite)
• The Scale Managers GetScreenOrientation function will now check for window.orientation first, because iOS mobile browsers have an incomplete implementation of the Screen API, forcing us to use the window value as a priority. This means the Scale Manager will now emit orientationchange events correctly on iOS. Fix #4361 #4914 (thanks @pfdtravalmatic @jackfreak @cuihu)
• Time.Clock.addEvent can now take an instance of a TimerEvent as its parameter. Fix #5294 (thanks @samme @EmilSV)
• GameConfig.audio now defaults to an empty object, which simplifies access to the config in later checks (thanks @samme)
• The Loader.path was being added to the File URL even if the URL was absolute. This is now checked for and the path is not applied unless the URL is relative (thanks @firesoft)
