Expand the TestCpp project in VS2010, and the following contains 46 sample directories. In addition, it also includes: (1) AppDelegate. h/cpp: program control class AppDelegate. (2) controller. h/cpp: The Example Scenario Management class TestController, used to display the menus of all examples. (3) testBasic. h/cpp: The base class TestScene of the sample scenario, which is used to return to the main interface scenario. (4) testResource. h: File resource name string definition header file (5) tests. h: Sample header file. (6) main. h/cpp: main function and header file. The following describes each file in detail.

(1) AppDelegate. h/cpp: the two files are program control class AppDelegate. The specific code is as follows:

// AppDelegate. h # ifndef _ APP_DELEGATE_H _ # define _ APP_DELEGATE_H _ # include "cocos2d. h "class AppDelegate: private cocos2d: CCApplication // AppDelegate class private inherits from CCApplication {public: AppDelegate (); // constructor virtual ~ AppDelegate (); // destructor virtual bool applicationDidFinishLaunching (); // This method will be called after the application is started. The default implementation includes the virtual void applicationDidEnterBackground () required after the game is started; // this method is called when the application enters the background. virtual void applicationWillEnterForeground (); // This method is paired with the previous method and called when the application returns to the foreground .}; # Endif // _ APP_DELEGATE_H _

This header file is the same as that described in study note 1. The following is an analysis of the cpp file.

# Include "AppDelegate. h "# include" cocos2d. h "# include" controller. h "// display the menu header file # include" SimpleAudioEngine. h "// background music playback header file USING_NS_CC; using namespace CocosDenshion; // declare the namespace to use SimpleAudioEngine. hAppDelegate: AppDelegate () // constructor {} AppDelegate ::~ AppDelegate () // destructor {// SimpleAudioEngine: end ();} bool AppDelegate: applicationDidFinishLaunching () // the startup program calls the function {// initialize director: initialize the game engine controller CCDirector to enable the game engine CCDirector * pDirector = CCDirector: sharedDirector (); pDirector-> setOpenGLView (CCEGLView: sharedOpenGLView ()); // set the scene display CCSize screenSize = CCEGLView: Export dopenglview ()-> getFrameSize (); // obtain the screen size CCSize designSize = CCSizeMake (480,320 ); // design the screen size CCFileUtils * pFileUtils = CCFileUtils: sharedFileUtils (); // if (screenSize. height> 320) // {CCSize resourceSize = CCSizeMake (960,640); std: vector
