VisualShader¶
Inherits: Shader < Resource < RefCounted < Object
A custom shader program with a visual editor.
Description¶
This class allows you to define a custom shader program that can be used for various materials to render objects.
The visual shader editor creates the shader.

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 the list of all nodes in the shader with the specified type.
Vector2 get_node_position ( Type type, int id ) const
Returns the position of the specified node within the shader graph.
int get_valid_node_id ( Type type ) const

bool has_varying ( String name ) const
Returns true if the shader has a varying with the given name.
bool is_node_connection ( Type type, int from_node, int from_port, int to_node, int to_port ) 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.
