I am trying the barrier effect as shown in the make your own game vids and it works great if i have a default animation which in turn i have a collision box. But what can I do to have a collision in the game the user can't see. I am doing this to restrict movement from right to left to simulate a kind of horizontal jump effect... Player clicks the screen which causes the ball to move and barrier would then bounce him back. Pretty much exactly what Gltch does I just dont want to show the barrier as part of the game.
