    Collision Problem (racing game)

    Hey, I'm new here, and I'm also fairly new to flash, I am having a problem with making collision boundries in flash, and I want you help... here is what I have so far... The instance "land" is the boundry, this script is on the car.

    onClipEvent (enterFrame) {
    //This code will advance the car forward.
    if (Key.isDown(Key.UP)) {
    speed += .5;
    }
    // This will make the car go backwards
    if (Key.isDown(Key.DOWN)) {
    speed -= .5;
    }
    //The car will start to slow down after the speed of 10
    if (Math.abs(speed)>5) {
    speed *= .5;
    }
    // This will change the angle of the car
    if (Key.isDown(Key.LEFT)) {
    _rotation -= 4;
    }
    if (Key.isDown(Key.RIGHT)) {
    _rotation += 4;
    }
    // here is where the hittest is for the boundary
    speed *= .98;
    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 *= -.6;
    }
    }

    My problem is, when I hit the boundry straight on, It works, but when I rotate on the boundry, I can go right through it with the car. I want a way so that the car can't rotate on the boundry, or if I can't do that, a way that even if the car does rotate, it can't go through the wall.

    Actually, no, it barley hangs over it at all. That isnt a collision problem, your just being fussy
