In Chapter 6, Project: Moving Hands and Feet, we made the avatar look like it was walking. Now we need to make it look as though it can turn when we switch directions. Turning, or rotating, is not new to us—we already make the avatar turn when flipping and cartwheeling. But this time we want to make our avatar face a particular direction.
