i was making a quick thing where you could use the arrow keys to drive a car around in an arena and wanted to add in other cars that moved around randomly which you could crash into.

i managed to program the player car,

code:

onClipEvent (enterFrame) {

if (Key.isDown(Key.UP)) {

speed += 2;

} else {

if (Key.isDown(Key.DOWN)) {

speed -= 1;

} else {

speed *= .9;

}

}

if (Math.abs(speed)>25) {

speed *= .6;

}

if (Key.isDown(Key.LEFT)) {

_rotation -= speed;

}

if (Key.isDown(Key.RIGHT)) {

_rotation += speed;

}

speed *= .9;

x = Math.sin(_rotation*(Math.PI/180))*speed;

y = Math.cos(_rotation*(Math.PI/180))*speed*-1;

if (!_root.land.hitTest(_x+x, _y+y, true)) {

_x += x;

_y += y;

} else {

speed *= -.5;

}

}

but i cant program the computer car to move randomly based upon the same physics.

working with flash 5, please help
