I have created this code to bounce the ball when user clicks on the mouse. But the ball doesn’t bounce as I wanted it to be.

I am attaching the fla also, If anyone can help me I will be glad.

ymov = 10;  
ymovball = -200;  
gravity = .95;  
gravityball = 0.25;  
speed = 3;  
\_root.onEnterFrame = function() {  
ymov += gravity;  
ball.\_y += ymov;  
if (ball.\_y \> 400) {  
ball.\_y = 400;  
ymov _= Math.sin(-1/speed);  
}  
}  
ball.onRelease = function() {  
ymovball = gravityball + ymovball;  
ball.\_y += ymovball;  
ymovball += Math.sin(gravityball_ymovball)/speed;  
}

Thanks in Advance:cons:
