anyone have any solutions??

I think that it would be the same way you created the collision.

Change your letters to movie clip and create two key frames at frame 1 and fram 10.

In frame 10 change the alpha of the letter to o% and then motion tween them.

Now go back to your game and enter the codes so that if the ball moves over the letter play the movie clip and it will disappear.
