The Pipeline Manager is responsible for the creation, activation, running and destruction of WebGL Pipelines and Post FX Pipelines in Phaser 3.
The WebGLRenderer
owns a single instance of the Pipeline Manager, which you can access
via the WebGLRenderer.pipelines
property.
By default, there are 9 pipelines installed into the Pipeline Manager when Phaser boots:
You can add your own custom pipeline via the PipelineManager.add
method. Pipelines are
identified by unique string-based keys.

This map stores all pipeline instances in this manager.
This is populated with the default pipelines in the boot
method.
This map stores all Post FX Pipeline classes available in this manager.
As of v3.60 this is now populated by default with the following Post FX Pipelines:
These are added as part of the boot process.
If you do not wish to add them, specify disableFX: true
in your game config.
See the FX Controller class for more details about each FX.
An array of all post-pipelines that are created by this manager.

This is set when clearPipeline
is called and restored in rebindPipeline
if none is given.

The Render Target index. Used internally by the methods in this class. Do not modify directly.
Adds a pipeline instance to this Pipeline Manager.
The name of the instance must be unique within this manager.
Make sure to pass an instance to this method, not a base class.
For example, you should pass it like this:
this.add('yourName', new CustomPipeline(game));`
and not like this:
this.add('yourName', CustomPipeline);`
To add a Post Pipeline, see addPostPipeline
instead.

Adds a Post Pipeline to this Pipeline Manager.
Make sure to pass a base class to this method, not an instance.
For example, you should pass it like this:
this.addPostPipeline('yourName', CustomPipeline);`
and not like this:
this.addPostPipeline('yourName', new CustomPipeline());`
To add a regular pipeline, see the add
method instead.

Copy the source

The difference with this copy is that no resizing takes place. If the source
Render Target is larger than the target
then only a portion the same size as
the target
dimensions is copied across.
You can optionally set the brightness factor of the copy.

Flushes the current pipeline being used and then clears it, along with the
the current shader program and vertex buffer from the WebGLRenderer
.
Then resets the blend mode to NORMAL.
Call this before jumping to your own gl context handler, and then call rebind
when
you wish to return control to Phaser again.

The difference between this method and drawFrame
is that this method
uses a faster copy shader, where only the brightness can be modified.

instead.
The copy itself is handled by the Utility Pipeline.

Binds the source
Render Target and then copies a section of it to the target
Render Target.
This method is extremely fast because it uses gl.copyTexSubImage2D
and doesn't
require the use of any shaders. Remember the coordinates are given in standard WebGL format,
where x and y specify the lower-left corner of the section, not the top-left. Also, the
copy entirely replaces the contents of the target texture, no 'merging' or 'blending' takes
place.

This Pipeline Manager instance.
Pops the framebuffer from the renderers FBO stack and sets that as the active target,
then draws the source
Render Target to it. It then resets the renderer textures.
This should be done when you need to draw the final results of a pipeline to the game
canvas, or the next framebuffer in line on the FBO stack. You should only call this once
in the onDraw
handler and it should be the final thing called. Be careful not to call
this if you need to actually use the pipeline shader, instead of the copy shader. In
those cases, use the bindAndDraw
method.

source | Phaser.Renderer.WebGL.RenderTarget |
The Render Target to draw from. |
Destroy the Pipeline Manager, cleaning up all related resources and references.
Copy the source
Render Target to the target
Render Target, using the
given Color Matrix.
The difference between this method and copyFrame
is that this method
uses a color matrix shader, where you have full control over the luminance
values used during the copy. If you don't need this, you can use the faster
copyFrame
method instead.
The copy itself is handled by the Utility Pipeline.

This method is called by the WebGLPipeline.batchQuad
method, right after a quad
belonging to a Game Object has been added to the batch.
It is also called directly bu custom Game Objects, such as Nine Slice or Mesh, from their render methods.
It causes a batch flush, then calls the postBatch
method on the Post FX Pipelines
belonging to the Game Object.
It should be preceeded by a call to preBatch
to start the process.

postBatch
method on the post-fx pipelines belonging to the Camera.

This method is called by the WebGLPipeline.batchQuad
method, right before a quad
belonging to a Game Object is about to be added to the batch.
It is also called directly bu custom Game Objects, such as Nine Slice or Mesh, from their render methods.
It causes a batch flush, then calls the preBatch
method on the Post FX Pipelines
belonging to the Game Object.
It should be followed by a call to postBatch
to complete the process.

Use this to reset the gl context to the state that Phaser requires to continue rendering.
Calling this will:

, and then wish to return
rendering control to Phaser again.
