cocosd怎么在一定时间后场景切换

仿造HelloWorldScene 写就好啦

COCOS2DX 是场景的切换，比如 菜单 场景 ，游戏 场景， 当你进入游戏 场景 ，菜单 场景就

会删掉，减少内存空间

所用你要切换场景的类都能仿造这个写
CCScene* HelloWorld::scene(){ CCScene * scene = NULL; do { // ;scene; is an autorelease object scene = CCScene::create(); CC_BREAK_IF(! scene);
// ;layer; is an autorelease object HelloWorld *layer = HelloWorld::create(); CC_BREAK_IF(! layer);
// add layer as a child to scene scene-;addChild(layer); } while (0);
// return the scene return scene;}

//切换场景过程
CCScene *pScene; g_iGameState = iType; if(iType == GAME_MENU) { pScene = CCTransitionFade::transitionWithDuration(1.0f, CGameMenu::scene()); } else if(iType == GAME_RUN) { pScene = CCTransitionFade::transitionWithDuration(1.0f, CGameSelectCus::scene()); } else if (iType == GAME_OVER) { pScene = CCTransitionFlipX::transitionWithDuration(2.0f, CGameOver::scene()); }
CCDirector::sharedDirector()-;replaceScene(pScene);

一个是创建 场景 ，一个是切换 ，CCTransitionFade::transitionWithDuration()这个是切换场景时候的动画效果
