Improving aiming – option 2

The previous solution is acceptable, but there is another possibility. Instead of the arrow bouncing back and forth, you can aim by moving the mouse side-to-side. The benefit of this option is that you're not limited to 180 degrees of motion.

To accomplish this, you can make use of a particular input event: InputEventMouseMotion. This event occurs when the mouse moves, and returns with it a relative property representing how far the mouse moved in the previous frame. You can use this value to rotate the arrow by a small amount.

First, disable the arrow animation by removing the SET_ANGLE portion from _process(). Next, add the following code to _input():

func _input(event):    if event is InputEventMouseMotion: if ...
