By animating our actors further, we can breath life into them. We can give our players/users the illusion of a vibrant, living world.

In essence, programming animation is the art of illusion. By adding small movements or image changes at the right time, we beguile our users into believing our creations are more than just static pixels on a screen. In this chapter, you will learn the following techniques for animating Greenfoot actors:
