Hi,

Im trying to figure out how to create a flash scratch card, has anyone come across some code that might help, i figured i could use a drawing mc to form a growing mask that reveals the picture underneath. But i have had trouble with dynamic masks before, has any one tried anything similar, or seen anything anywhere else?

Cheers.
