ActionScript 2.0 :: Make A Shooter From A Bird's View Perspective?

I was trying to make a shooter from a bird's view perspective...So far I've got my character which is a simple circle, and a rectangle protruding from him (the gun), and it rotates depending on where the mouse is located.I've also got a custom cursor set in, to add some kind of excitement...Here's the dumb question... How do I get it so that whenever I click (shoot) the cursor movieclip will play a certain frame inside of itself? I want it to do something like:

Code:
on(release){
gotoAndPlay(2);
}

It just says that I can't have mouse functions unless it's a button.I was thinking of just making a huge button that covers the whole stage, set the alpha to 0, and when that button is clicked, it will play what I want it to play.
