Making the ball in Blocker game more smooth (Chapter 6)
I tried the Blocker game in Chapter 6 on iPhone simulator, and on real, physical devices iPhone 4S and the New iPad. There is a phenomenon that, I see the ball moving about 3 pixels each time, but sometimes, it won't move for a split second, and then it moves for 5, 6 or 7 pixels, if feels like. So the movement is a bit jagged at times.
I don't see it happening in Angry Birds. Could it be the way how sub-view is rendered in the main view. Would the same issue be there if we use a "frame buffer" so we paint everything all at once? How can it be improved so that animation of the ball is very smooth?
