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.

Sets the default texture to be used with a texture uniform. The default is used if a texture is not set in the [ShaderMaterial].

<member name="code" type="String" setter="set_code" getter="get_code" default="""">
|
|
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.
