Summary
Nowadays, it seems like everybody in the world has played or will play a physics-based
game at some point in their lives. Box2D is by far the most popular engine in the casual
games arena. The commands you learned here can be found in pretty much every port of
the engine, including a JavaScript one that is growing in popularity as we speak.
Setting up the engine and getting it up and running is remarkably simple—perhaps too
much so. A lot of testing and value tweaking goes into developing a Box2D game and
pretty soon you learn that keeping the engine performing as you wish is the most important
skill to master when developing physics-based games. Picking the right values for friction,
density, restitution, damping, time step, PTM ratio, and so on can make or break your
game.
In the next chapter, we'll continue to use Box2D, but we'll focus on what else Cocos2d-x
can do to help us organize our games.
