paddle game and moving buttons

[bob58]

I have a paddle game where the ball bounces of the paddle and hits blocks. (nothing special) It works but i was wondering is there a way to make it so that the ball bounces at a different angle if it hits the very edge of the paddle.

Heres the code for the paddle:

onClipEvent (enterFrame) {
if (Key.isDown(Key.RIGHT)) {
if (this._x<=485) {
this._x += 13;
}
}
if (Key.isDown(Key.LEFT)) {
if (this._x>=25) {
this._x -= 13;
}
}
}


and heres the code for the ball :

onClipEvent (load) {
dir = Math.round(Math.random()*1);
speed = 15;
if (dir == 1) {
var Ang = 45;
} else {
var Ang = 135;
}
xspeed = speed*Math.cos((Ang)*Math.PI/180);
yspeed = speed*Math.sin((Ang)*Math.PI/180);
}
onClipEvent (enterFrame) {
this._x += xspeed;
this._y += yspeed;
if ((this._x<=5) || (this._x>=495)) {
xspeed = -xspeed;
}
if ((this._y<=5) || (_root.pad.hitTest(this))) {
yspeed = -yspeed;
}
if (this._y>420) {
_root.lives -= 1;
_root.score -= 10;
if (_root.lives == 0) {
_root.gotoAndPlay(5);
}
_x = 150;
_y = 100;
dir = Math.round(Math.random()*1);
speed = 15;
if (dir == 1) {
var Ang = 45;
} else {
var Ang = 135;
}
xspeed = speed*Math.cos((Ang)*Math.PI/180);
yspeed = speed*Math.sin((Ang)*Math.PI/180);
}
}

If anyone knows how to help please post
by the wat does anyone know how to make a moving button
oh yah, and i am using MX
