I'm coding a zap-tap type zapper for iphone, so you can just tap the ducks, etc. I can trigger the zapper just fine, and get the coordinates of the tap just fine; problem seems to be that, even if I freeze frames, I don't see any frame where there are white rectangles being drawn. I have one frame that is black, one or more frames that are just background (no sprites), and then the sprites come back.
Am I supposed to be drawing the rectangles myself? It seems like I shouldn't even need to bother with this, then, except that I need to somehow know when it's checking each sprite for a hit. So I guess my question is, if I'm supposed to draw these rectangles myself (or at least know which sprite is being hit), how can I figure out which one to be drawing / checking?
