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.

Enumerations

enum Type:

• TYPE_VERTEX = 0 —- A vertex shader, operating on vertices.

• TYPE_FRAGMENT = 1 —- A fragment shader, operating on fragments (pixels).

• TYPE_LIGHT = 2 —- A shader for light calculations.

• TYPE_MAX = 3 —- Represents the size of the Type enum.

Constants

• NODE_ID_INVALID = -1

• NODE_ID_OUTPUT = 0

Property Descriptions

• Vector2 graph_offset

The offset vector of the whole graph.

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

• 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.
