How to find the the change in position with a touch?
Basically, I am making a game where the user drags his finger and the change in position in the x and y affects the starting speed of a ball object (think Angry Birds). I have no clue how to approach this given that the ball isn't released until the touch is completed. Is there a way to make an arrow that shrinks or increases based upon how much power will be applied?
