That method gets crazy out of hand with more than 2 sprites, you'd have to put If Object 1 is not touched, if Object 2 is not touched etc infinite amounts of conditions for every overlap check with different object types, plus that still wouldn't work with multiple instances of the same object, it assumes SpriteA is always on top and then SpriteB etc as it checks them in order. My above method handles any number of overlapped objects with one event.
