初学试试看cocos2dx的TestCPP框架(2) --CCApllication

--------------------------CCApllication类-----------------------------

cocos2dx肯定会从CCApplication是派生出一个类，一般来说，这个派生类会重写下面3个虚函数

[cpp] view plaincopyprint?

1. //初始化scene与CCDirector  
2. virtual bool applicationDidFinishLaunching();  
3. //窗口恢复时候调用SIZE_RESTORED  
4. virtual void applicationWillEnterForeground();  
5. //窗口最小化时候调用SIZE_MINIMIZED  
6. virtual void applicationDidEnterBackground();  

示范代码：

[cpp] view plaincopyprint?

1. bool AppDelegate::applicationDidFinishLaunching()  
2. {  
3.     // initialize director  
4.     CCDirector *pDirector = CCDirector::sharedDirector();  
5.     pDirector->setOpenGLView(CCEGLView::sharedOpenGLView());  
6.   
7.     CCSize screenSize = CCEGLView::sharedOpenGLView()->getFrameSize();  
8.   
9.     CCSize designSize = CCSizeMake(480, 320);  
10.       
11.     if (screenSize.height > 320)  
12.     {  
13.         CCSize resourceSize = CCSizeMake(960, 640);  
14.         CCFileUtils::sharedFileUtils()->setResourceDirectory("hd");  
15.         pDirector->setContentScaleFactor(resourceSize.height/designSize.height);  
16.     }  
17.   
18.     CCEGLView::sharedOpenGLView()->setDesignResolutionSize(designSize.width, designSize.height, kResolutionNoBorder);  
19.   
20.     // turn on display FPS  
21.     pDirector->setDisplayStats(true);  
22.   
23.     // set FPS. the default value is 1.0/60 if you don't call this  
24.     pDirector->setAnimationInterval(1.0 / 60);  
25.   
26.     CCScene * pScene = CCScene::create();  
27.     CCLayer * pLayer = new TestController();  
28.     pLayer->autorelease();  
29.   
30.     pScene->addChild(pLayer);  
31.     pDirector->runWithScene(pScene);  
32.   
33.     return true;  
34. }  
35.   
36. // This function will be called when the app is inactive. When comes a phone call,it's be invoked too  
37. void AppDelegate::applicationDidEnterBackground()  
38. {  
39.     CCDirector::sharedDirector()->stopAnimation();  
40.     SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();  
41.     SimpleAudioEngine::sharedEngine()->pauseAllEffects();  
42. }  
43.   
44. // this function will be called when the app is active again  
45. void AppDelegate::applicationWillEnterForeground()  
46. {  
47.     CCDirector::sharedDirector()->startAnimation();  
48.     SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();  
49.     SimpleAudioEngine::sharedEngine()->resumeAllEffects();  
50. }
