My problem lies in the fact that the bullets are only accurately shot from when the position where the player spawns and as the player moves away from this spawning position the it gradually breaks down to the point where the mouse is being clicked on one side and the bullets fly out to another spot. I've tried alternate methods that don't require trig but they don't seem to work at all.
No errors are produced when complied and run.
