I'm not sure I'm clear on your question. Would actual rotation (setting the angle) of the sprite work for you needs? Or, do you need an animation (cycling through the sprite sheet) of the sprite rolling while it is moving?
Oh no, just to make it 'Roll'...rotate around. As for now, it's just one sprite (a Ball Circle) but in the future it may have multiple sprites.
Ok. I got it working a bit....I used the Set Angle and the formula (self.Angle + 100*dt).
Thanks if I have any other questions, I'll post
