Spacing Test- I roughed out some spaces and placed a coin at each point (shot the animation) and got a feel for the speed the ball would move at. I decided that each bounce should average 17-18 frames.
sorry, the scanner didn't want to keep the drawing straight that day.
Path Test- Originally, I wanted to use a simple racquetball court for the environment, but I felt it didn't offer enough visual interest. So, I drew out my under layer path and numbered, in order, where the ball hits the ground.
Animation, I know the ball's hard to see. It's starting far back in perspective. It's in the top left of the screen.
