WebGL Multi-Texture Rendering

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 drawcall-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.
• WebGL.Utils.checkShaderMax is a new function, used internally by the renderer, to determine the maximum number of texture units the GPU + browser supports.
• The property WebGLRenderer.currentActiveTextureUnit has been renamed to currentActiveTexture.
• WebGLRenderer.startActiveTexture is a new read-only property contains the current starting active texture unit.
• WebGLRenderer.maxTextures is a new read-only property that contains the maximum number of texture units WebGL can use.
• 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.
• WebGLRenderer.currentTextures has been removed, as it's no longer used internally.
• WebGLRenderer.setBlankTexture no longer has a force parameter, as it's set by default.
• The Mesh Game Object WebGL Renderer function has been updated to support multi-texture units.
• The Blitter Game Object WebGL Renderer function has been updated to support multi-texture units.
• The Bitmap Text Game Object WebGL Renderer function has been updated to support multi-texture units.
• The Dynamic Bitmap Text Game Object WebGL Renderer function has been updated to support multi-texture units.
• The Particle Emitter Game Object WebGL Renderer function has been updated to support multi-texture units.
• The Texture Tint vertex and fragment shaders have been updated to support the inTexId float attribute and dynamic generation.
• 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 tha 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.

Forward Diffuse Light Pipeline API Changes

This Light2D pipeline, which is responsible for rendering lights under WebGL, has been rewritten to work with the new Texture Tint Pipeline functions. 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
• modelIdentity is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.Identity
• modelScale is now available as a stand-alone function Phaser.Renderer.WebGL.MVP.Scale
• 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.

New Features

• WebGLRenderer.setInt1iv will allow you to look-up and set a 1iv uniform on the given shader.

Updates and API Changes

• 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.

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.
• 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)
