There you are.
You missed the point where I said
"You will also need to set the angle of the image to
angle(0,0,velocityX, velocityY)".
I also took the liberty of adjusting 'rolling' to around the correct amount, so the animation looks accurate.
Nice idea with the ball shine, you are going to have to do something about picking the other balls, if you want multiple shines/ball animations. I'd assign a 'baseUID' or something instance variable for each of the shines/animations, then apply their events only repspective to the ball of that UID.
Hope I helped!
