Well, I figured out a solution that's working so far using two families, one that contains all of the enemy sprites and another that contains their collision boxes. The sprites family has a collisionUID variable to store the UID of its appropriate collision box.
Assigning the collision box's UID by distance using "pick nearest to" and iterating through every sprite to check which ones need the flashing effect both seem a little sloppy to me. Maybe there's a better a way? For the moment though, I'm just happy to have something that works.kirbyUFO2013-08-01 15:06:28
