I think I may have explained my issue badly. All of the sprites are already on the same layer, and each sprite is different (so not many copies of one sprite).
I want to be able to separately pick up each of the sprites with the mouse. The problem is, because they?re stacked directly on top of each other, I can only select the sprite at the top of the stack. That's why I need a way to push a button and change the sprites z-order, so that I can make an individual sprite come to the top of the stack. Can using families help me with this?
Thanks again for your help.
