Hi guys, I have been tackling this problem all day and not getting anywhere… Basically I have a turret that should aim at the mouse. Simple right? Apparently not. Check it out:

```auto

//This function (should) rotate the gun to aim at a particular point
//Called from the enterframe event
public function aim(e:Event) {
    var dx:Number = mouseX - this.x;
    var dy:Number = (mouseY - this.y) * -1;
    var newAngle:Number = Math.atan2(dy,dx)*180/Math.PI;
    if (dx < 0) newAngle += 180;
    if (dx >= 0 && dy < 0) newAngle += 360;
            
    this.rotation = (newAngle * -1) + 90;
    trace(rotation);
}

```

If you have any ideas on what I did wrong please let me know.

The above function is within a Gun class which is a movieclip that has been added as a child to the stage.

Thanks!
