See the v3 to v4 Migration Guide for step-by-step code changes, removed APIs, and a migration checklist. Overview: What Changed in v4 Phaser 4 is a complete overhaul of the WebGL rendering engine. The v3 renderer let each subsystem manage WebGL state independently, causing conflicts (e.g. certain FX breaking Masks). v4 centralizes WebGL state management through a RenderNode graph, where each node handles exactly one rendering task. Key Removals v3 Feature v4 Replacement Pipeline RenderNode (per-task rendering nodes) FX ( preFX / postFX ) Filters ( filters.internal / filters.external ) BitmapMask FilterMask (via filters system) GeometryMask (WebGL) FilterMask (Canvas still uses GeometryMask) Derived FX: Bloom, Circle, Gradient, Shine Actions ( AddEffectBloom , AddEffectShine , AddMaskShape ) or GameObjects Mesh and Plane Removed (proper 3D planned for future) Point Use Vector2 instead Key Additions New GameObjects : CaptureFrame , Gradient , Noise , NoiseCell2D/3D/4D , NoiseSimplex2D/3D , SpriteGPULayer , Stamp , TilemapGPULayer New Components : Lighting , RenderSteps , RenderNodes New Tint Modes : MULTIPLY , FILL , ADD , SCREEN , OVERLAY , HARD_LIGHT New Filters : Blend, Blocky, CombineColorMatrix, GradientMap, ImageLight, Key, Mask, NormalTools, PanoramaBlur, ParallelFilters, Quantize, Sampler, Threshold GL Orientation : v4 uses standard GL orientation (Y=0 at bottom for textures) Filters System (Replacing FX and BitmapMask) Full reference: filters-and-postfx.md Filters unify the v3 FX and Mask systems. Every filter takes an input image and produces an output image via a shader pass. Filters can be applied to any game object or camera -- v3 had restrictions on which objects supported FX. // v3 approach (FX): sprite. preFX . addGlow ( 0xff00ff , 4 ); sprite. postFX . addBlur ( 0 , 2 , 2 , 1 ); // v4 approach (Filters): sprite. enableFilters (); sprite. filters . internal . addGlow ( 0xff00ff , 4 , 0 , 1 ); sprite. filters . external . addBlur ( 0 , 2 , 2 , 1 ); // v3 approach (BitmapMask): const mask = new Phaser . Display . Masks . BitmapMask (scene, maskImage); sprite. setMask (mask); // v4 approach (FilterMask): sprite. enableFilters (); sprite. filters . internal . addMask (maskImage); Internal vs External : Internal filters run before the camera transform (object-local space, cheaper). External filters run after (screen space, full-resolution). RenderNodes (Replacing Pipelines) In v3, a Pipeline was a rendering system that often handled multiple responsibilities. In v4, each RenderNode handles a single rendering task via its run() method. Some nodes also have a batch() method to accumulate state before drawing. Architecture The RenderNodeManager (on the WebGL renderer) owns all render nodes. Game objects reference nodes through role-based maps. // RenderNode roles on a game object: // - 'Submitter': runs other node roles for each element // - 'Transformer': provides vertex coordinates // - 'Texturer': handles textures // GameObjects have default and custom render node maps: gameObject. defaultRenderNodes // built-in nodes per role gameObject. customRenderNodes // overrides per role gameObject. renderNodeData // data keyed by node name Setting Custom RenderNodes // Override a specific render role: gameObject. setRenderNodeRole ( 'Submitter' , 'MyCustomSubmitter' ); // Pass data to a render node: gameObject. setRenderNodeRole ( 'Transformer' , 'MyTransformer' , { customProperty : 42 }); // Remove a custom node (falls back to default): gameObject. setRenderNodeRole ( 'Submitter' , null ); Built-in RenderNode Types Batch Handlers (accumulate and draw multiple objects per draw call): BatchHandlerQuad -- standard quad batching (Image, Sprite, BitmapText, etc.) BatchHandlerQuadSingle -- single-quad variant BatchHandlerTileSprite -- TileSprite batching BatchHandlerTriFlat -- flat triangle batching (Graphics, Shape) BatchHandlerPointLight -- point light batching BatchHandlerStrip -- triangle strip batching Submitters (coordinate rendering per object type): SubmitterQuad , SubmitterTile , SubmitterTileSprite SubmitterSpriteGPULayer , SubmitterTilemapGPULayer Transformers (compute vertex positions): TransformerImage , TransformerStamp , TransformerTile , TransformerTileSprite Texturers (manage texture binding): TexturerImage , TexturerTileSprite Filters (post-processing -- see filters-and-postfx.md ): BaseFilter , BaseFilterShader FilterBarrel , FilterBlend , FilterBlocky , FilterBlur (Low/Med/High variants) FilterBokeh , FilterColorMatrix , FilterCombineColorMatrix FilterDisplacement , FilterGlow , FilterGradientMap , FilterImageLight FilterKey , FilterMask , FilterNormalTools , FilterPanoramaBlur FilterParallelFilters , FilterPixelate , FilterQuantize FilterSampler , FilterShadow , FilterThreshold , FilterVignette , FilterWipe Other : Camera , FillCamera , FillRect , FillPath , FillTri DrawLine , StrokePath , ShaderQuad ListCompositor , RebindContext , YieldContext DynamicTextureHandler Extending: Custom RenderNodes // Register a custom node constructor: renderer. renderNodes . addNodeConstructor ( 'MyNode' , MyNodeClass ); // Or add a pre-built node instance: renderer. renderNodes . addNode ( 'MyNode' , myNodeInstance); New Game Objects CaptureFrame Captures the current framebuffer contents to a texture at the point in the display list where it sits. Does not render anything itself. WebGL only. // Everything above this in the display list gets captured: const image1 = this . add . image ( 400 , 300 , 'background' ); // Enable framebuffer usage on the camera: this . cameras . main . setForceComposite ( true ); // Create the capture point: const capture = this . add . captureFrame ( 'myCapturedTexture' ); // Use the captured texture on another object: const overlay = this . add . image ( 400 , 300 , 'myCapturedTexture' ); // Add filters to the overlay to distort the captured scene Key details: Requires camera.setForceComposite(true) or a framebuffer context (Filters, DynamicTexture, camera with partial alpha) Inside a Container with filters, captures only that Container's contents Setting visible = false stops capturing Components: BlendMode, Depth, RenderNodes, Visible Source : src/gameobjects/captureframe/CaptureFrame.js Gradient Displays GPU-rendered color gradients. Extends Shader . Supports linear, radial, and other shape modes with configurable ColorRamp containing ColorBand objects. // Simple linear gradient: const grad = this . add . gradient ( undefined , 100 , 100 , 200 , 200 ); // Complex radial gradient with multiple color bands: const halo = this . add . gradient ({ bands : [ { start : 0.5 , end : 0.6 , colorStart : [ 0.5 , 0.5 , 1 , 0 ], colorEnd : 0xffffff , colorSpace : 1 , interpolation : 4 }, { start : 0.6 , end : 1 , colorStart : 0xffffff , colorEnd : [ 1 , 0.5 , 0.5 , 0 ], colorSpace : 1 , interpolation : 3 } ], dither : true , repeatMode : 1 , shapeMode : 2 , // radial start : { x : 0.5 , y : 0.5 }, shape : { x : 0.5 , y : 0.0 } }, 400 , 300 , 800 , 800 ); // Animate: halo. offset = 0.1 * ( 1 + Math . sin (time / 1000 )); Key details: Config: GradientQuadConfig with bands , shapeMode , repeatMode , start , shape , dither Colors defined via ColorRamp with ColorBand objects (supports HSV, various interpolation modes) Call gradient.ramp.encode() after modifying ramp data at runtime Source : src/gameobjects/gradient/Gradient.js Noise Game Objects All noise types extend Shader and are WebGL only.

Up to 100x faster than individual sprites. WebGL only. const layer = this . add . spriteGPULayer (texture, size); // size = max number of members // Add members (do this all at once, not incrementally): const member = { x : 100 , y : 200 , frame : 'tree' , scaleX : 1 , scaleY : 1 , alpha : 1 }; layer. addMember (member); // Reuse the member object for efficiency with millions of entries: member. x = 300 ; member. y = 400 ; member. frame = 'bush' ; layer. addMember (member); // Enable lighting on the layer: layer. setLighting ( true ); Key details: Single texture only (no multi-atlas), single image per layer Members support tween-like animations (fade, bounce, wave, color shift) defined at creation Updating buffer contents is expensive -- populate once, leave unchanged Power-of-two textures recommended for pixel art to avoid seaming \"Remove\" members visually by setting scaleX/scaleY/alpha to 0 (avoids buffer rebuild) Components: Alpha, BlendMode, Depth, ElapseTimer, Lighting, Mask, RenderNodes, TextureCrop, Visible Source : src/gameobjects/spritegpulayer/SpriteGPULayer.js New Components Full component reference: game-object-components.md Lighting Component Replaces the v3 approach of assigning a lighting pipeline. WebGL only. // v3 approach: sprite. setPipeline ( 'Light2D' ); // v4 approach: sprite. setLighting ( true ); // Self-shadowing (simulates surface shadows from texture brightness): sprite. setSelfShadow ( true , 0.5 , 1 / 3 ); // Args: enabled, penumbra (lower = sharper), diffuseFlatThreshold (0-1) // Use game-wide default for self-shadow: sprite. setSelfShadow ( null ); // reads from config.render.selfShadow Supported on : BitmapText, Blitter, Graphics, Shape, Image, Sprite, Particles, SpriteGPULayer, Stamp, Text, TileSprite, Video, TilemapLayer, TilemapGPULayer. Batching note : Lighting changes the shader, which breaks batches. Group lit objects together and unlit objects together for best performance. Source : src/gameobjects/components/Lighting.js RenderSteps Component Allows injecting custom logic into the render process of a game object. WebGL only. The Filters system uses RenderSteps internally. // Add a custom render step: gameObject. addRenderStep ( function ( renderer, gameObject, drawingContext, parentMatrix, renderStep, displayList, displayListIndex ) { // Custom rendering logic here // Call next step when ready: var nextFn = gameObject. _renderSteps [renderStep + 1 ]; if (nextFn) { nextFn (renderer, gameObject, drawingContext, parentMatrix, renderStep + 1 , displayList, displayListIndex); } }); Key details:",
