--------------------------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
//初始化scene与CCDirector virtual bool applicationDidFinishLaunching(); //窗口恢复时候调用SIZE_RESTORED virtual void applicationWillEnterForeground(); //窗口最小化时候调用SIZE_MINIMIZED virtual void applicationDidEnterBackground();
bool AppDelegate::applicationDidFinishLaunching() { // initialize director CCDirector *pDirector = CCDirector::sharedDirector(); pDirector->setOpenGLView(CCEGLView::sharedOpenGLView()); CCSize screenSize = CCEGLView::sharedOpenGLView()->getFrameSize(); CCSize designSize = CCSizeMake(480, 320); if (screenSize.height > 320) { CCSize resourceSize = CCSizeMake(960, 640); CCFileUtils::sharedFileUtils()->setResourceDirectory("hd"); pDirector->setContentScaleFactor(resourceSize.height/designSize.height); } CCEGLView::sharedOpenGLView()->setDesignResolutionSize(designSize.width, designSize.height, kResolutionNoBorder); // turn on display FPS pDirector->setDisplayStats(true); // set FPS. the default value is 1.0/60 if you don't call this pDirector->setAnimationInterval(1.0 / 60); CCScene * pScene = CCScene::create(); CCLayer * pLayer = new TestController(); pLayer->autorelease(); pScene->addChild(pLayer); pDirector->runWithScene(pScene); return true; } // This function will be called when the app is inactive. When comes a phone call,it's be invoked too void AppDelegate::applicationDidEnterBackground() { CCDirector::sharedDirector()->stopAnimation(); SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic(); SimpleAudioEngine::sharedEngine()->pauseAllEffects(); } // this function will be called when the app is active again void AppDelegate::applicationWillEnterForeground() { CCDirector::sharedDirector()->startAnimation(); SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic(); SimpleAudioEngine::sharedEngine()->resumeAllEffects(); }
