Shader

Inherits: Resource < RefCounted < Object

Inherited By: VisualShader

A shader implemented in the Godot shading language.

Description

A custom shader program implemented in the Godot shading language, saved with the .gdshader 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.

Properties

Methods

Enumerations

enum Mode: 🔗

Mode MODE_SPATIAL = 0

Mode used to draw all 3D objects.

Mode MODE_CANVAS_ITEM = 1

Mode used to draw all 2D objects.

Mode MODE_PARTICLES = 2

Mode used to calculate particle information on a per-particle basis. Not used for drawing.

Mode MODE_SKY = 3

Mode used for drawing skies. Only works with shaders attached to Sky objects.

Mode MODE_FOG = 4

Mode used for setting the color and density of volumetric fog effect.

Property Descriptions

String code = "" 🔗

• void set_code(value: String)

• String get_code()

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

Method Descriptions

Texture2D get_default_texture_parameter(name: StringName, index: int = 0) const 🔗

Returns the texture that is set as default for the specified parameter.

Note: name must match the name of the uniform in the code exactly.

Note: If the sampler array is used use index to access the specified texture.

Mode get_mode() const 🔗

Returns the shader mode for the shader.

Array get_shader_uniform_list(get_groups: bool = false) 🔗

Get the list of shader uniforms that can be assigned to a ShaderMaterial, for use with ShaderMaterial.set_shader_parameter and ShaderMaterial.get_shader_parameter. The parameters returned are contained in dictionaries in a similar format to the ones returned by Object.get_property_list.

If argument get_groups is true, parameter grouping hints will be provided.

void set_default_texture_parameter(name: StringName, texture: Texture2D, index: int = 0) 🔗

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

Note: name must match the name of the uniform in the code exactly.

Note: If the sampler array is used use index to access the specified texture.
