Flash Animation Assistance Needed

Hi guys. I have a project I'm working on and I am really stumped on making a seemingly simple animation work.

The animation is of a coin scratching off a layer to reveal the layer beneath. I have the coin animated, and the layers in place. I am wanting to know if there is a way to erase/delete every place the coin passes over the stage, revealing the layer beneath. I've seen animations where ActionScript is used to allow a user to control the coin/pointer and activate the "scratch-off" effect. However, I am trying to come up with a method that is not a user-initiated animation since I want the effect to repeat in several places in the timeline.

For the life of me I cannot figure out how to make this work. I am a moderately skilled Flash user and an ActionScript novice.

I am using Flash CS4 on a SnowLeopard Mac.

Any assistance or advice would be appreciated. Thanks.

You need to put the layer you want to reveal on top of the layer you want to show to begin with. Then you use a mask to reveal the parts you want to. You can animate the mask layer like any other layer, either using a tween or a frame-by-frame animation.

Ok, I'm going to try this. I'd already attempted the frame by frame animation. I placeed the layer that was to be "scratched" off on top of the reveal layer, set it as a graphic symbol and deleted the parts passed over by the coin in each frame, Which was upwards of 90 frames and 90 seperate graphic symbols. It was a mess and I was convinced there had to be an easier way.

Thanks grapefrukt. That worked. Learned something new today. Now I am trying to tween multiple masks on that layer. The Coin swipes across the stage three times. The first swipe is a mask and works great, but when the coin animation comes back for the second and third pass, the masks start to tween together, like a shape tween. I'm working on that now. Sure it's just something I neglected.Thanks again.
