Several questions are related to opacity and invisible (and collisions)
I have a TOUCH event on a sprite object...
1- if my sprite object is at 0 opacity, will it still work on touch?
2- if my sprite object is invisible, will,it still work on touch?
3- if my sprite object has COLLISION DISABLED, will it still work on touch (or does this just effect collision with other objects)?
4- if I have two TOUCH objects overlapping slightly, which object will work on touch (the top object?)
