' Set up the example using a mesh grid, cube, cone, and a nurbs cube:

set oRoot = activesceneroot

/*

	This example demonstrates how to find Cluster objects

*/

NewScene( null, false );

var obj = CreatePrim( "Cube", "MeshSurface" );

CreateCluster("cube.pnt[2,3,6,LAST]");

CreateCluster("cube.poly[1]");

// find the cluster using the siType constant.

var cls = obj.activeprimitive.geometry.clusters.find( siPolygonCluster );

if ( cls != null )

	logmessage( "found polygon cluster: " + cls.fullname ); 

//Expected results:

#

# 	This example demonstrates how to to find PlayControl Property objects 

# 	under the scene root

#

PlayCtrlProp = Application.ActiveProject.Properties.Find( "PlayControl" )

try :

	if Application.ClassName(PlayCtrlProp) == "Property" :

		Application.LogMessage( "PlayControl property OK" )

	else :

		Application.LogMessage( "PlayControl property NOT found" )

except :

	Application.LogMessage( "PlayControl property NOT found" )

# Output of above script:

#INFO : PlayControl property OK
