Class VisualShader

Namespace
Godot
Assembly
GodotSharp.dll

This class provides a graph-like visual editor for creating a Shader. Although VisualShaders do not require coding, they share the same logic with script shaders. They use VisualShaderNodes that can be connected to each other to control the flow of the shader. The visual shader graph is converted to a script shader behind the scenes.

Parameters

method godot_string_name

Name of the method to check for.

Returns

bool

HasGodotClassSignal(in godot_string_name)

Check if the type contains a signal with the given name. This method is used by Godot to check if a signal exists before raising it. Do not call or override this method.

Parameters

signal godot_string_name

Name of the signal to check for.

Returns

bool

HasVarying(string)

Returns true if the shader has a varying with the given name.

public bool HasVarying(string name)

Parameters

name string

Returns

bool

InvokeGodotClassMethod(in godot_string_name, NativeVariantPtrArgs, out godot_variant)

Invokes the method with the given name, using the given arguments. This method is used by Godot to invoke methods from the engine side. Do not call or override this method.
