Methods

(static) changeParameter(nodeName, componentName, parameterName, …params)

Changes a node or component parameter. Equivalent of the changeParameter() API call.
Parameters:
Name Type Attributes Description
nodeName string Name of the node. If multiple nodes share the same name, only the first one will be affected.
componentName string Name of the component. If the name of the component is null or an empty string, the node itself will be affected.
parameterName string Name of the parameter. See the documentation for more info.
params any <repeatable>
 New parameter value. See the examples below.
Examples
// Sets the 'face1' node 'u_color' shader vec4 uniform to (1.0, 0.5, 0.0, 1.0).
Utility.changeParameter('face1', 'MeshRenderer', 'u_color', 1.0, 0.5, 0.0, 1.0);
// Sets the 'mesh.04' node position to (1, 3.5, -2.82).
Utility.changeParameter('mesh.04', null, 'position', 1, 3.5, -2.82);
// Disables the 'my_node' node.
Utility.changeParameter('my_node', '', 'enabled', false);

(static) findFaceIdInHierarchy() → {uint}

Returns:
The face index. Possible values are 0 (first face), 1 (second face), 2 (third face) and 3 (fourth face).
Type
uint

(static) fireTrigger(triggerName)

Fires a custom trigger. Only one trigger can be fired each frame.
Parameters:
Name Type Description
triggerName string Name of the custom trigger.
Throws:

Type
Error
Returns:
The name of the fired custom trigger.
Type
string

(static) getTriggerState(triggerType, faceIdopt) → {bool}

Parameters:
Name Type Attributes Description
triggerType TriggerType The trigger type.
faceId int <optional>
 The face index. Accepted values are -1 (auto face), 0 (first face), 1 (second face), 2 (third face) and 3 (fourth face).
Returns:
True if a given trigger type state is set for the given face index, false otherwise.
Type
bool

(static) getTriggerStateChanged(triggerType, faceIdopt) → {bool}

Checks if the trigger state has changed.
Parameters:
Name Type Attributes Description
triggerType TriggerType The trigger type.
faceId int <optional>
 The face index. Accepted values are -1 (auto face), 0 (first face), 1 (second face), 2 (third face) and 3 (fourth face).
Returns:
