Bouncing Ball (Ball Dribble) Animation Using Flash And Action Script
This Flash script will result in animation of a ball that will be bounced when it hit a floor (ball dribbling). You can even move the ball. Click on it and hold to stop the bouncing and then release the mouse to continue bouncing. What we need to produce the animation is just a movie clip an a simple script.
