hi,
that's one problem indeed, that's where custom actions comes in. Also This is something that the Unity Api should expose as properties, but it's always a difficult situation, because when scripting, that never is a problem, it's only when you want to add an abstraction layers that some API becomes difficult/impossible to port properly in a visual environment. Vectrosity is a typical example cause it follows the same API patterns, using very powerful method signatures, which makes it impossible to expose properly visually ( almost impossible)
bye,
Jean
