VisualShader¶
Inherits: Shader < Resource < RefCounted < Object
A custom shader program with a visual editor.
描述¶
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.

Method Descriptions¶
void add_node ( Type type, VisualShaderNode node, Vector2 position, int id )
Adds the specified node to the shader.
void add_varying ( String name, VaryingMode mode, VaryingType type )
Adds a new varying value node to the shader.
bool can_connect_nodes ( Type type, int from_node, int from_port, int to_node, int to_port ) const
Returns true if the specified nodes and ports can be connected together.
Error connect_nodes ( Type type, int from_node, int from_port, int to_node, int to_port )
Connects the specified nodes and ports.
void connect_nodes_forced ( Type type, int from_node, int from_port, int to_node, int to_port )
Connects the specified nodes and ports, even if they can't be connected. Such connection is invalid and will not function properly.
void disconnect_nodes ( Type type, int from_node, int from_port, int to_node, int to_port )
Connects the specified nodes and ports.
VisualShaderNode get_node ( Type type, int id ) const
Returns the shader node instance with specified type and id.
Dictionary[] get_node_connections ( Type type ) const
Returns the list of connected nodes with the specified type.
PackedInt32Array get_node_list ( Type type ) const

Returns true if the specified node and port connection exist.
void remove_node ( Type type, int id )
Removes the specified node from the shader.
void remove_varying ( String name )
Removes a varying value node with the given name. Prints an error if a node with this name is not found.
void replace_node ( Type type, int id, StringName new_class )
Replaces the specified node with a node of new class type.
