A custom shader program.

This class allows you to define a custom shader program that can be used by a [ShaderMaterial]. Shaders allow you to write your own custom behavior for rendering objects or updating particle information. For a detailed explanation and usage, please see the tutorials linked below.

<description>
|
|
Returns the texture that is set as default for the specified parameter.
|
|
[b]Note:[/b] [code]param[/code] must match the name of the uniform in the code exactly.

<method name="get_mode" qualifiers="const">
|
|
<return type="int" enum="Shader.Mode" />
|
|
<description>
|
|
Returns the shader mode for the shader, either [constant MODE_CANVAS_ITEM], [constant MODE_SPATIAL] or [constant MODE_PARTICLES].

<description>
|
|
Returns [code]true[/code] if the shader has this param defined as a uniform in its code.
|
|
[b]Note:[/b] [code]param[/code] must match the name of the uniform in the code exactly.

<description>
|
|
Sets the default texture to be used with a texture uniform. The default is used if a texture is not set in the [ShaderMaterial].
|
|
[b]Note:[/b] [code]param[/code] must match the name of the uniform in the code exactly.

|
|
Returns the shader's code as the user has written it, not the full generated code used internally.

</member>
|
|
<member name="custom_defines" type="String" setter="set_custom_defines" getter="get_custom_defines" default="""">
|
|
Returns the shader's custom defines. Custom defines can be used in Godot to add GLSL preprocessor directives (e.g: extensions) required for the shader logic.
|
|
[b]Note:[/b] Custom defines are not validated by the Godot shader parser, so care should be taken when using them.
