Class: WebGLPipeline

Phaser.Renderer.WebGL. WebGLPipeline

The WebGLPipeline is a base class used by all of the core Phaser pipelines.

It describes the way elements will be rendered in WebGL. Internally, it handles compiling the shaders, creating vertex buffers, assigning primitive topology and binding vertex attributes, all based on the given configuration data.

The pipeline is configured by passing in a WebGLPipelineConfig object. Please see the documentation for this type to fully understand the configuration options available to you.

Usually, you would not extend from this class directly, but would instead extend from one of the core pipelines, such as the Multi Pipeline.

The pipeline flow per render-step is as follows:

  1. onPreRender - called once at the start of the render step
  2. onRender - call for each Scene Camera that needs to render (so can be multiple times per render step)
  3. Internal flow: 3a) bind (only called if a Game Object is using this pipeline and it's not currently active) 3b) onBind (called for every Game Object that uses this pipeline) 3c) flush (can be called by a Game Object, internal method or from outside by changing pipeline)
  4. onPostRender - called once at the end of the render step

onActive(currentShader)

By default this is an empty method hook that you can override and use in your own custom pipelines.

This method is called every time the Pipeline Manager makes this the active pipeline. It is called at the end of the WebGLPipeline.bind method, after the current shader has been set. The current shader is passed to this hook.

For example, if a display list has 3 Sprites in it that all use the same pipeline, this hook will only be called for the first one, as the 2nd and 3rd Sprites do not cause the pipeline to be changed.

If you need to listen for that event instead, use the onBind hook.

Parameters:
Name Type Description
currentShader Phaser.Renderer.WebGL.WebGLShader

The shader that was set as current.
Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 1037)

onAfterFlush( [isPostFlush])

By default this is an empty method hook that you can override and use in your own custom pipelines.

This method is called immediately after this pipeline has finished flushing its batch.

It is called after the gl.drawArrays call.

You can perform additional post-render effects, but be careful not to call flush on this pipeline from within this method, or you'll cause an infinite loop.

To apply changes pre-render, see onBeforeFlush.

Parameters:
Name Type Argument Default Description
isPostFlush boolean <optional>
 false

Was this flush invoked as part of a post-process, or not?
Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 1202)

onBatch( [gameObject])

By default this is an empty method hook that you can override and use in your own custom pipelines.

This method is called every time the batchQuad or batchTri methods are called. If this was as a result of a Game Object, then the Game Object reference is passed to this hook too.

This hook is called after the quad (or tri) has been added to the batch, so you can safely call 'flush' from within this.

Note that Game Objects may call batchQuad or batchTri multiple times for a single draw, for example the Graphics Game Object.

Parameters:
Name Type Argument Description
gameObject Phaser.GameObjects.GameObject <optional>

The Game Object that invoked this pipeline, if any.
Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 1091)

onBeforeFlush( [isPostFlush])

By default this is an empty method hook that you can override and use in your own custom pipelines.

This method is called every time this pipeline is asked to flush its batch.

It is called immediately before the gl.bufferData and gl.drawArrays calls are made, so you can perform any final pre-render modifications. To apply changes post-render, see onAfterFlush.

Parameters:
Name Type Argument Default Description
isPostFlush boolean <optional>
 false

Was this flush invoked as part of a post-process, or not?
Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 1185)

onBind( [gameObject])

By default this is an empty method hook that you can override and use in your own custom pipelines.

This method is called every time a Game Object asks the Pipeline Manager to use this pipeline, even if the pipeline is already active.

Unlike the onActive method, which is only called when the Pipeline Manager makes this pipeline active, this hook is called for every Game Object that requests use of this pipeline, allowing you to perform per-object set-up, such as loading shader uniform data.

Parameters:
Name Type Argument Description
gameObject Phaser.GameObjects.GameObject <optional>

The Game Object that invoked this pipeline, if any.
Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 1058)

Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 493)

once(event, fn [, context])

Add a one-time listener for a given event.

Parameters:

onDraw(renderTarget)

This method is only used by Post FX Pipelines and those that extend from them.

This method is called every time the postBatch method is called and is passed a reference to the current render target.

At the very least a Post FX Pipeline should call this.bindAndDraw(renderTarget), however, you can do as much additional processing as you like in this method if you override it from within your own pipelines.

Parameters:
Name Type Description
renderTarget Phaser.Renderer.WebGL.RenderTarget

The Render Target.
Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 951)

Parameters:

gameObject Phaser.GameObjects.GameObject <optional>

The Game Object that invoked this pipeline, if any.
Since: 3.50.0

onPostRender()

By default this is an empty method hook that you can override and use in your own custom pipelines.

This method is called once per frame, after all rendering has happened and snapshots have been taken.

It is called at the very end of the rendering process, once all Cameras, for all Scenes, have been rendered.

Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 1170)

onPreBatch( [gameObject])

Name Type Argument Description
gameObject Phaser.GameObjects.GameObject <optional>

The Game Object that invoked this pipeline, if any.
Since: 3.50.0

onPreRender()

By default this is an empty method hook that you can override and use in your own custom pipelines.

This method is called once per frame, right before anything has been rendered, but after the canvas has been cleared. If this pipeline has a render target, it will also have been cleared by this point.

Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 1140)

onRebind()

By default this is an empty method hook that you can override and use in your own custom pipelines.

This method is called when the Pipeline Manager needs to rebind this pipeline. This happens after a pipeline has been cleared, usually when passing control over to a 3rd party WebGL library, like Spine, and then returing to Phaser again.

Since: 3.50.0
Source: src/renderer/webgl/WebGLPipeline.js (Line 1077)

onRender(scene, camera)

By default this is an empty method hook that you can override and use in your own custom pipelines.

postBatch( [gameObject])

This method is called as a result of the WebGLPipeline.batchQuad method, right after a quad belonging to a Game Object has been added to the batch. When this is called, the renderer has just performed a flush.
