How to obtain absolute coordinates?

Currently, if I were to add display objects to separate groups and move the groups by different dx dy or even rotate, the xy coordinates of the objects return the value relative to the separate group’s reference point.

This breaks the physics engine. So I was wondering if there’s any way that I could obtain the absolute coordinates of each display object on screen? [import]uid: 108204 topic_id: 20456 reply_id: 320456[/import]
