VBScript Example

'
'  This example demonstrates how to use the Undo option in scripting by 
'  using the DataRepository (internal object database) to see whether
'  the object exists in the scene at each step (creating the object, 
'  deleting, and then undoing the DeleteObj call)
'

NewScene , false
dim nIdentifier
set oDatabase = XSIUtils.DataRepository
set oCone = CreatePrim( "Cone", "MeshSurface" )
nIdentifier = oDatabase.GetIdentifier( oCone )

LogMessage oDatabase.HasData( nIdentifier )
'INFO : True

DeleteObj( "Cone" )
LogMessage oDatabase.HasData( nIdentifier )
'INFO : False

Undo
LogMessage oDatabase.HasData( nIdentifier )
'INFO : True
