Getting UID of unknown colliding object.

Is there a way to test for collision with an object bearing a particular UID, but could be any number of different objects? Say in one playthrough, a bullet might collide with your object. Another time a player might. A third time a fireball might, etc, etc, ad nauseum. What if you don't know (at the time of making the game) what might be colliding during run time, but want to get it's UID and check to see if that particular UID is still around several ticks later?

You can only test for the collision in the first place if you know what to test against, so the point is moot. If you want to abstract the object, you would use Families.

blackhornet So you can test for collision with an object that is a member of a family of objects? I have not looked at that feature yet. If that works, I owe you a thanks!

blackhornet Read up on families, and they are EXACTLY what I need, and will continue to be tremendously usefull to me. So, THANKS!
