Add a hidden sprite so it appears under the hole and fits exactly the shape of the bottom of the hole. Put the z order of this sprite above the ball z position so that, as the ball moves down, it will appear to disappear. Make sure the new sprite's color / pattern matches the image behind it and you won't see it - the example below uses a different color to highlight the image.

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 :)

this is what i done...just for test purpose...for the overlaping Edges when coming from another angle/side ill be looking the solution for that,to make the "hole effect" around in 360 degrees no matter where it comes from ;)

heres the capx, you can drag/drop the ball for test
