|
A custom shader program implemented in the Godot shading language, saved with the [code].gdshader[/code] extension.
|
|
This class is used by a [ShaderMaterial] and allows you to write your own custom behavior for rendering visual items or updating particle information. For a detailed explanation and usage, please see the tutorials linked below.

Returns the texture that is set as default for the specified parameter.
|
|
[b]Note:[/b] [param name] must match the name of the uniform in the code exactly.
|
|
[b]Note:[/b] If the sampler array is used use [param index] to access the specified texture.

Get the list of shader uniforms that can be assigned to a [ShaderMaterial], for use with [method ShaderMaterial.set_shader_parameter] and [method ShaderMaterial.get_shader_parameter]. The parameters returned are contained in dictionaries in a similar format to the ones returned by [method Object.get_property_list].
|
|
If argument [param get_groups] is true, parameter grouping hints will be provided.

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] [param name] must match the name of the uniform in the code exactly.
|
|
[b]Note:[/b] If the sampler array is used use [param index] to access the specified texture.
