Create an animation that has two phases. In the first phase the user is asked to enter an x-velocity. This screen has an input box and a button. After they enter the input velocity and click the button the animation moves to phase two. Here a single gargoyle bounces around. It's x-velocity is set equal to the velocity entered by the user in phase 1. Note: your .fla should have two frames, one for phase 1 and one for phase 2. You should use gotoAndPlay() to jump from phase 1 to phase 2. Don't forget the stop() commands in each frame.
