Thx, that will work fine for what i need
but how about if the ball comes from the bottom? I think i would need to invert the trick and put another "invisible" sprite at the top...so to make the trick then i need to get where from is coming the ball, if from the top or bottom, and finally applying the z-order to the respective bottom/top sprite...
and when the ball complete overlaps that invisible sprite, destroy it or make it spawn in other location as a Portal game hehe, i will post a capx later
thx again ill try that and the idea i got from your reply...of course any other method is always welcome
