Initializing the game

In the code files of this chapter, you will find JumpAndRun_init.zip, which includes an initial project that we will use as the basis for the rest of the chapter.

We are not going to see the classes in depth, but let's take a look at the most important things so you understand the rest of the development process.

The game that we are going to develop is a platform game starring our old Yeti friend, who after escaping from the killer snowballs must climb some snow platforms to avoid falling into the abyss. That's why there are three different classes besides GameScene: Yeti, Floor, and Platform.

If you open Yeti.h, you will see that it derives from CCNode and that we have defined the following enumeration:
