cocos2d-x ——HelloWorld

其他部分不需要修改,只需要改变HelloWorldScene.cpp的init()方法即可

#include "HelloWorldScene.h"

using namespace cocos2d;

    CCScene * scene = NULL;

        CC_BREAK_IF(! scene);

        // 'layer' is an autorelease object
        HelloWorld *layer = HelloWorld::node();
        CC_BREAK_IF(! layer);

        // add layer as a child to scene
        scene->addChild(layer);
    } while (0);

    // return the scene
    return scene;
}

// on "init" you need to initialize your instance
bool HelloWorld::init()
{
    bool bRet = false;
    do 
    {
        //////////////////////////////////////////////////////////////////////////
