VisualShader

Inherits: Shader < Resource < Reference < 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.

Properties

Vector2

graph_offset

Vector2( 0, 0 )

Method Descriptions

void add_node ( Type type, VisualShaderNode node, Vector2 position, int id )

Adds the specified 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.

---

Array get_node_connections ( Type type ) const

Returns the list of connected nodes with the specified type.

---

PoolIntArray 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

There is currently no description for this method. Please help us by contributing one!

---

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 set_mode ( Mode mode )

Sets the mode of this shader.

---

void set_node_position ( Type type, int id, Vector2 position )

Sets the position of the specified node.
