el constructor thanks a lot for the quick reply and C3P example. this gives me another way of trying to do it. right now i am trying with the bullet behavior:
-> Sprite: Set Bullet speed to distance(Sprite.X,Sprite.Y,Touch.X,Touch.Y)×10
-> Sprite: Set Bullet angle of motion to angle(Sprite.X,Sprite.Y,Touch.X,Touch.Y) degrees
One thing to note is that your example allows you to continue swiping and flinging the ball. I am looking for only one swipe/fling. I figured out I can do this by adding a fling/swipe area around the start of the ball, and as long as the ball is overlapping with the swipe/fling area, it will fling. if not, it won't. so I think that works.
thanks again. I think I may switch this to physics.
