Cocos2d for iPhone 1 Game Development Cookbook

By: Nathan Burba

Overview of this book

Cocos2d for iPhone is a robust but simple-to-use 2D game framework for iPhone. It is easy to use, fast, flexible, free, and Appstore approved. More than 2500 AppStore games already use it, including many best-seller games. Do you want to take your cocos2d game development skills to the next level and become more professional in cocos2d game design? Cocos2d for iPhone 1 Game Development Cookbook will help you reach that next level. You will find over 100 recipes here that explain everything from the drawing of a single sprite to AI pathfinding and advanced networking. Full working examples are emphasized. Starting with the first chapter, Graphics, you will be taken through every major topic of game development. You will find both simple and complex recipes in the book. Each recipe is either a solution to a common problem (playing video files, accelerometer steering) or a cool advanced technique (3D rendering, textured polygons). This cookbook will have you creating professional quality iOS games quickly with its breadth of working example code.

Accessing the Cocos2d-iPhone testbed

The Cocos2d-iPhone testbed is a suite of examples created to test bugs, display features, and instruct programmers with useful examples. In this recipe we will introduce this very useful tool.

Getting ready

First, we must download the Cocos2d source from http://www.cocos2d-iphone.org/download. After unzipping the main source package, double-click on the cocos2d.xcworkspace file.

How to do it...

From the Scheme selection menu in XCode you can now select which piece of the testbed you would like to run. These tests include everything—drawing, physics, sound, networking, and more.

How it works...

Inside the tests folder in the cocos2d-ios target you will find the source files for each individual test. Here you can play around with the demos to get ideas for your own games.

Box2D testbed

Due to the scope of the Cocos2d-iPhone framework, many other testbeds are included within the Cocos2d-iPhone testbed. By building the Box2dTestBed scheme we can run a version...
