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

<instance> onActive(currentShader)

Description:

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:

Source: src/renderer/webgl/WebGLPipeline.js#L1478
Since: 3.50.0

---

onAfterFlush

<instance> onAfterFlush([isPostFlush])

Description:

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:

Source: src/renderer/webgl/WebGLPipeline.js#L1643
Since: 3.50.0

---

onBatch

<instance> onBatch([gameObject])

Description:

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:

Source: src/renderer/webgl/WebGLPipeline.js#L1532
Since: 3.50.0

---

onBeforeFlush

<instance> onBeforeFlush([isPostFlush])

Description:

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:

Source: src/renderer/webgl/WebGLPipeline.js#L1626
Since: 3.50.0

---

onBind

<instance> onBind([gameObject])

Description:

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:

Source: src/renderer/webgl/WebGLPipeline.js#L1499
Since: 3.50.0

---

onBoot

<instance> onBoot()

onDraw

<instance> onDraw(renderTarget, [swapTarget])

Description:

This method is only used by Sprite FX and 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.

---

onRebind

<instance> onRebind()

Description:

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