use 2 families to separate both spites in own sol.
[quote:23z26szy]"Is there any way to tell if an object is obscured?"
store width and height of object in pv, use a temp to loop thru each pixel to check if its obscured. or you can look at my cap here the example uses while loop so if your objects aren't too huge its ok.
or periodically you can create temp copy sprite that starts in the center and expands until its the original sprites size (as long as its overlapping both original and another sprite, otherwise its destroyed) and when it reaches original size, destroy them both.. because its completely covered.
with that last example. you should have a 1 px sprite in a contrainer with your "overlapperer" and always have the 1 px sprite move in another direction 1 px away from the overlapperer each time it overlaps the overlapperer. the overlapperer expands its width/height to w/e direction the 1 px sprite moves. if it expands and doesn't overlap them all (original sprite, another sprite and 1px), its destroyed.... i can come back with pics if you didnt get that.
the last method may be faster than per pixel but its not perfect. per pixel would seem better if its not going to trigger often.
