Source.AddProperty
 
 
 

Source.AddProperty

Introduced

v4.0

Description

Creates and adds a UserDataBlob or CustomProperty to a Source object.

C# Syntax

Property Source.AddProperty( Object in_Preset, Boolean in_Branch, String in_name );

Scripting Syntax

oReturn = Source.AddProperty( Preset, [BranchFlag], [Name] );

Return Value

CustomProperty, UserDataBlob or UserDataMap, depending on the preset that was used.

Parameters

Parameter Type Description
Preset String This argument contains either the name of a Property Preset or a string with the filename or full path to a Preset file.

Note: Only CustomProperty Presets, UserDataBlob Presets, and UserDataMap Presets are valid for sources.

The type of property that is created is determined by this argument. For example, "CustomProperty" creates an empty CustomProperty and "UserDataBlob" creates a UserDataBlob.
BranchFlag Boolean False is the only supported value

Default Value: false

Name String Represents the name of the new property (see SIObject.Name). If not specified the object is named based on the Preset argument.

Examples

JScript Example

/*
        This example shows how to add user data to a shape source
*/
// First build a simple scene 
NewScene( null, false );
var oCone = ActiveSceneRoot.AddGeometry( "Cone", "MeshSurface" );
// Set up the time in seconds
var oPlayCtrl = GetValue("PlayControl");
var dFrameRate = oPlayCtrl.Parameters("Rate").Value;
var dTime = 1.0 * dFrameRate;                                   // start at the beginning
// Using SaveShapeKey stores the source and applies the clip simultaneously
var aIndices = new Array( 1,4,7,10,13,16,19,22,25 );
var aPositions = new Array( /*    X,        Y,        Z         */
