Hi what i basically am trying to do with my game is create an arrow that is fixed to a certain point and when the user drags from that point with a mouse click or a touch input an arrow is drawn behind their finger or mouse. The length of the arrow should always be in relation to the players finger or mouse position. If i did a bad job of explaining it here is a visual representation of what I am trying to achieve.

Also imagine the angry birds slingshot without elasticity. Kind of like a piece of bubble gum.
