Check the gravity tutorial. You’ll find some explanation there.

pom :+)

Here is a paddle code that I use for my breaking blocks game… I think you might find it useful…

```php

if (_root.paddle.hitTest(_root.ball))
{
     dotx = _root.ball._x;
     padx = _root.paddle._x;

     xspeed = ((dotx - padx) / 10) * 2;
     yspeed *= -1;
}

```

This worked very well for a paddle that scrolled along the x axis… If you have paddles that move up and down howveer… Just change every instance of x you see in that code to a y and y to a x…

xspeed and yspeed are the speed that the ball is traveling… If you multiple it by -1… It will reverse it’s course… This works very very well 🙂

Thnaks marz that is helpful…Vvery…

But see iv’e been learning that tutorial on gravity and its super helpful.

All i need to basically do is the computer paddle first

I dont know how to…

well i have a hitTest but it wont work…

Ill show you…

```php
onClipEvent (load) {
    gravity = 1;
    bounce = 1;
    speedx = 29;
    speedy = 10;
    speedyy = 10;//I added this
}
onClipEvent (enterFrame) {
    speedy = speedy+gravity;
    this._y -= speedyy/5;//And this
    this._x += speedx/45;
    this._y += speedy/5;
    if (this.hitTest(_root.paddle)) {
        speedy *= -bounce;
        if (this.hitTest(_root.com)) {//Then this
            speedyy *= -bounce;
        }
    }
}
{

```

Those re the only things i added to try making a computer paddle actually allow the ball to bounce…

But he doesent sem to coaparate

Maybe somOne can help…

Easy man… Lower your x and y speeds down!

Hehe… The ball is jumping OVER the paddle and therefore isn’t technically hitting it… Make them around 4 or 5… And then make your frames per second somewhere around 40…

Faster frames per second with lower pixel rates… Will make for a very smooth game…

I’ll take another look at the code in a little while… But that is the first thing you might wanna change…

Peace
