背包基本功能：

    1.存放物品

    2.穿戴装备(套装、武器、宠物等)

    3.待定功能(出售、合成、排序)

如图：

    在做此功能先，要先在AppDelegate类添加搜索资源目录，否则会因资源问题导致各种崩～～～

AppDelegate.cpp

bool AppDelegate::applicationDidFinishLaunching() {
    // initialize director
    CCDirector* pDirector = CCDirector::sharedDirector();
    CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();

    pDirector->setOpenGLView(pEGLView);
	
    // 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);

    
    CCSize screenSize = CCEGLView::sharedOpenGLView()->getFrameSize();
    
    CCSize designSize = CCSizeMake(480, 320);
    
    CCFileUtils* pFileUtils = CCFileUtils::sharedFileUtils();
    
    if (screenSize.height > 320)
    {
        CCSize resourceSize = CCSizeMake(960, 640);
        std::vector<std::string> searchPaths;
        searchPaths.push_back("hd");
        pFileUtils->setSearchPaths(searchPaths);
        pDirector->setContentScaleFactor(resourceSize.height/designSize.height);
    }
    
    CCEGLView::sharedOpenGLView()->setDesignResolutionSize(designSize.width, designSize.height, kResolutionShowAll);

    CocosGUIExamplesEquipScene *pScene = new CocosGUIExamplesEquipScene();
    pScene->autorelease();
    
    // run
    pDirector->runWithScene(pScene);
    
    
    
    // create a scene. it‘s an autorelease object
//    CCScene *pScene = HelloWorld::scene();
//
//    // run
//    pDirector->runWithScene(pScene);

    return true;
}

    注：大家最好看下cocos2d-x ,容器及常用API使用方法，如：CCDictionary、hitTest(碰撞检测)等。

    如上，只是实现背包的基本功能，还有好多东西，需要改进。比如，仓库不应该使用已设定好的格子，最好使用动态变化的格子，这方便以后的格子扩展。

    在此，望广大网友，多多指教～～～
