Breakout style game: Bouncing ball games

I have Clickteam Fusion and The Game Factory 2. I am creating a Breakout style game. I want to get the following effect: When the ball collides the paddle and depending in which part of the paddle it touches the angle of bouncing changes in order to have better control over the ball. I have an example of an ActionScript 3.0 game created by my friend that has the effect I'm looking for using TGF2 and CF2:

Please, watch it and try to explain me how to get this bouncing effect in any Clickteam product!!!. Thanks! - Nicolás Matías Funtalas.

Thanks!. But I want that the angle of bouncing changee depending which zone of the paddle the ball touches. The Flash game in the video shows this behaviour when the ball collides with the paddle.

Yes. Post the link where i can download this arkanoid create by chris burrows

In Flash this is the formula to get this behaviour when the ball colides with paddle:

function bounceAgainstPaddle():void
{
var position:Number=ball.x-paddle.x;
var percent:Number=(position / (paddie.width - ball.width)) - .5;
ballVelocityX=percent*10;
ballVelocityY*=-1;
}

I memorized this formula. Can you explain me why it produces that behaviour of bouncing with the paddle depending which zone of it touches???
