GetConstrainedObjects

Introduced

v3.0

Description

Finds all the objects constrained to an X3DObject

Note: This command uses output arguments. C# and some scripting languages (such as JScript, PerlScript and Python) don't support arguments passed by reference so you need to use the best workaround for your situation:

For scripting languages this command returns an ISIVTCollection which you can use to get the output arguments.

For C# you can use the XSIApplication.ExecuteCommand method to call this command. ExecuteCommand packs the output arguments into a C# System.Object containing an Array of the output arguments (see Calling Commands from C#).

Scripting Syntax

GetConstrainedObjects( InputObj, OutputObjs );

Parameters

Parameter Type Description
InputObj String or X3DObject Object which is constraining other objects
OutputObjs XSICollection Returns the list of constrained objects

Examples

1. VBScript Example

'
'       This example demonstrates the GetConstrainedObjects command
'
NewScene , false
Create2DSkeleton 0, -0.2, 3.0, 0, 2, 0.2, 0, 90, 0, 4
Create2DSkeleton 0, -1, 2.0, 0, 4, 0.1, 0, 90, 0, 4
CreatePrim "Cube", "MeshSurface"
' Constrain two bones to the cube
ApplyCns "Position", "eff", "cube"
ApplyCns "Position", "eff1", "cube"
dim objCollection
call GetConstrainedObjects (Selection(0), objCollection)
logmessage "There are " & objCollection.Count & _
        " objects constrained to " & Selection(0)
logmessage "The first constrained object is " & objCollection.Item(0)
logmessage "The second constrained object is " & objCollection.Item(1)
' Expected results:
'INFO : There are 2 objects constrained to cube
'INFO : The first constrained object is eff1
'INFO : The second constrained object is eff

2. JScript Example

/*
        This example demonstrates the GetConstrainedObjects command
*/
NewScene( null, false ) ;
Create2DSkeleton( 0, -0.2, 3.0, 0, 2, 0.2, 0, 90, 0, 4 );
Create2DSkeleton( 0, -1, 2.0, 0, 4, 0.1, 0, 90, 0, 4 ) ;
CreatePrim( "Cube", "MeshSurface" ) ;
// Constrain both skeletons to the cube
ApplyCns( "Position", "eff", "cube" ) ;
ApplyCns( "Position", "eff1", "cube" ) ;
// JScript doesn't support output arguments but the 
// information is also available as a return value
var aRetArgs = GetConstrainedObjects(Selection(0) );
// There is only one output argument so it is
// first in the returned collection
var objCollection = aRetArgs(0) ;
logmessage( "There are " + objCollection.Count +
        " objects constrained to " + Selection(0) ) ;
logmessage( "The first constrained object is " + objCollection.Item(0) ) ;
logmessage( "The second constrained object is " + objCollection.Item(1) ) ;
//Expected results:
//INFO : There are 2 objects constrained to cube
//INFO : The first constrained object is eff1
//INFO : The second constrained object is eff
