Instances of the WebGLShader class belong to the WebGL Pipeline classes. When the pipeline is created it will create an instance of this class for each one of its shaders, as defined in the pipeline configuration.
This class encapsulates everything needed to manage a shader in a pipeline, including the
shader attributes and uniforms, as well as lots of handy methods such as set2f, for setting
uniform values on this shader.
Typically, you do not create an instance of this class directly, as it works in unison with
the pipeline to which it belongs. You can gain access to this class via a pipeline's shaders
array, post-creation.

uniforms

vertexComponentCount

vertexSize
vertexSize: number
Description:
The size, in bytes, of a single vertex.
This is derived by adding together all of the vertex attributes.
For example, the Multi Pipeline has the following attributes:
inPosition - (size 2 x gl.FLOAT) = 8 inTexCoord - (size 2 x gl.FLOAT) = 8 inTexId - (size 1 x gl.FLOAT) = 4 inTintEffect - (size 1 x gl.FLOAT) = 4 inTint - (size 4 x gl.UNSIGNED_BYTE) = 4
The total, in this case, is 8 + 8 + 4 + 4 + 4 = 28.
This is calculated automatically during the createAttributes method.

Public Methods
bind
<instance> bind([setAttributes], [flush])
Description:
Sets the program this shader uses as being the active shader in the WebGL Renderer.
This method is called every time the parent pipeline is made the current active pipeline.
Parameters:
name | type | optional | default | description |
|---|---|---|---|---|
setAttributes | boolean | Yes | false | Should the vertex attribute pointers be set? |
flush | boolean | Yes | false | Flush the pipeline before binding this shader? |
Returns: Phaser.Renderer.WebGL.WebGLShader - This WebGLShader instance.
Source: src/renderer/webgl/WebGLShader.js#L229
Since: 3.50.0
createAttributes
<instance> createAttributes(attributes)
Description:
Takes the vertex attributes config and parses it, creating the resulting array that is stored
in this shaders attributes property, calculating the offset, normalization and location
in the process.
Calling this method resets WebGLShader.attributes, WebGLShader.vertexSize and
WebGLShader.vertexComponentCount.
It is called automatically when this class is created, but can be called manually if required.
Parameters:
name | type | optional | description |
|---|---|---|---|
attributes | Array.<Phaser.Types.Renderer.WebGL.WebGLPipelineAttributeConfig> | No | An array of attributes configs. |
Source: src/renderer/webgl/WebGLShader.js#L167
Since: 3.50.0
createProgram
<instance> createProgram([vertSrc], [fragSrc])
Description:
This method will create the Shader Program on the current GL context.
If a program already exists, it will be destroyed and the new one will take its place.
After the program is created the uniforms will be reset and this shader will be rebound.
This is a very expensive process and if your shader is referenced elsewhere in your game those references may then be lost, so be sure to use this carefully.
However, if you need to update say the fragment shader source, then you can pass
the new source into this method and it'll rebuild the program using it. If you
don't want to change the vertex shader src, pass undefined as the parameter.
Parameters:
name | type | optional | description |
|---|---|---|---|
vertSrc | string | Yes | The source code of the vertex shader. If not given, uses the source already defined in this Shader. |
fragSrc | string | Yes | The source code of the fragment shader. If not given, uses the source already defined in this Shader. |
Returns: Phaser.Renderer.WebGL.WebGLShader - This WebGLShader instance.
Source: src/renderer/webgl/WebGLShader.js#L1172
Since: 3.60.0
createUniforms
<instance> createUniforms()
Description:
Sets up the WebGLShader.uniforms object, populating it with the names
and locations of the shader uniforms this shader requires.
It works by first calling gl.getProgramParameter(program.webGLProgram, gl.ACTIVE_UNIFORMS) to
find out how many active uniforms this shader has. It then iterates through them,
calling gl.getActiveUniform to get the WebGL Active Info from each one. Finally,
the name and location are stored in the local array.
This method is called automatically when this class is created.
Returns: Phaser.Renderer.WebGL.WebGLShader - This WebGLShader instance.
Source: src/renderer/webgl/WebGLShader.js#L353

syncUniforms
<instance> syncUniforms()
Description:
Repopulate uniforms on the GPU.
This is called automatically by the pipeline when the context is lost and then recovered. By the time this method is called, the WebGL resources are already recreated, so we just need to re-populate them.
