Getting Some Action

In the last chapter I covered how to load all those beautiful images created by your artists (or yourself) and draw them on the screen. You even saw some basic animation. But although they're important, sprites are like international supermodelsthey look great, but there's not a lot going on behind the scenes. (My apologies to all you supermodel readers.)

To bring your game objects to life, you need to simulate movement. To do this, you use physicsor, more specifically, dynamics (the area of physics relating to motion). Don't worry; I'll keep the math to a minimum.
