VisualShaderNode¶

Inherits: Resource < RefCounted < Object

Base class for VisualShader nodes. Not related to scene nodes.

描述¶

Visual shader graphs consist of various nodes. Each node in the graph is a separate object and they are represented as a rectangular boxes with title and a set of properties. Each node also has connection ports that allow to connect it to another nodes and control the flow of the shader.

Enumerations¶

enum PortType:

PortType PORT_TYPE_SCALAR = 0

Floating-point scalar. Translated to float type in shader code.

PortType PORT_TYPE_SCALAR_INT = 1

Integer scalar. Translated to int type in shader code.

PortType PORT_TYPE_SCALAR_UINT = 2

Unsigned integer scalar. Translated to uint type in shader code.

PortType PORT_TYPE_VECTOR_2D = 3

2D vector of floating-point values. Translated to vec2 type in shader code.

PortType PORT_TYPE_VECTOR_3D = 4

3D vector of floating-point values. Translated to vec3 type in shader code.

PortType PORT_TYPE_VECTOR_4D = 5

4D vector of floating-point values. Translated to vec4 type in shader code.

PortType PORT_TYPE_BOOLEAN = 6

Boolean type. Translated to bool type in shader code.

PortType PORT_TYPE_TRANSFORM = 7

Transform type. Translated to mat4 type in shader code.

PortType PORT_TYPE_SAMPLER = 8

Sampler type. Translated to reference of sampler uniform in shader code. Can only be used for input ports in non-uniform nodes.

PortType PORT_TYPE_MAX = 9

Represents the size of the PortType enum.

Property Descriptions¶

int output_port_for_preview = -1

void set_output_port_for_preview ( int value )
int get_output_port_for_preview ( )

Sets the output port index which will be showed for preview. If set to -1 no port will be open for preview.

Method Descriptions¶

void clear_default_input_values ( )

Clears the default input ports value.

int get_default_input_port ( PortType type ) const

Returns the input port which should be connected by default when this node is created as a result of dragging a connection from an existing node to the empty space on the graph.

Array get_default_input_values ( ) const

Returns an Array containing default values for all of the input ports of the node in the form [index0, value0, index1, value1, ...].

Variant get_input_port_default_value ( int port ) const

Returns the default value of the input port.

void remove_input_port_default_value ( int port )

Removes the default value of the input port.

void set_default_input_values ( Array values )

Sets the default input ports values using an Array of the form [index0, value0, index1, value1, ...]. For example: [0, Vector3(0, 0, 0), 1, Vector3(0, 0, 0)].

void set_input_port_default_value ( int port, Variant value, Variant prev_value=null )

Sets the default value for the selected input port.
