cocos2d场景切换-创新互联

开始学习cocos2d啦，加油啊！！！

第一个hello world界面

CREATE_FUNC(CMyLayer);

};

#include "MyLayer.h"

}

CMyLayer::~CMyLayer(void)

{

}

 CCScene *CMyLayer:: scence()

{

CMyLayer *pCMyLayer = CMyLayer::create();

pScence->addChild(pCMyLayer);

return pScence;

}

bool CMyLayer::  init()

{

CCLabelTTF *pLable = CCLabelTTF::create("HI Fighting..!!!","Arial",40);

pLable->setPosition(ccp(200,200));

this->addChild(pLable);

CCMenuItemImage *pCloseItem = CCMenuItemImage::create(

"CloseNormal.png",

"CloseSelected.png",

this,

menu_selector(CMyLayer::menuCloseCallback));

//CC_BREAK_IF(! pCloseItem);

// Place the menu item bottom-right conner.

pCloseItem->setPosition(ccp(CCDirector::sharedDirector()->getWinSize().width - 20, 20));

// Create a menu with the "close" menu item, it's an auto release object.

CCMenu* pMenu = CCMenu::create(pCloseItem, NULL);

pMenu->setPosition(CCPointZero);

 this->addChild(pMenu, 1);

//CC_BREAK_IF(! pMenu);

return true;

}

void CMyLayer::menuCloseCallback(CCObject* pSender)
