Chapter 4: Managing Animations with State Machines

In the last chapter, we created a minimal game engine, allowing for moving our main character around and playing a simple animation, but it's far from full-featured. There's no world to navigate, the only animation that plays is running, and Red Hat Boy (RHB) doesn't respond to any physics. At this point, if we wanted to retitle our game, it would be called Red Hat Boy and the Empty Void.

While that might be a fun title, it wouldn't make for a fun game.
