Cocos2d-x学习之实现类似android的菜单栏tabbar效果

直接上代码吧，参考了网上找的例子，自己做了小小的改动

主要实现代码：

CCMenuItemImage *pMainHome = CCMenuItemImage::create("main_1.png","main_1_sel.png",   this,menu_selector(HelloWorld::menuCloseCallback));CC_BREAK_IF(! pMainHome);CCMenuItemImage *pMainLocation = CCMenuItemImage::create("main_2.png","main_2_sel.png",   this,menu_selector(HelloWorld::menuCloseCallback));CC_BREAK_IF(! pMainLocation);CCMenuItemImage *pMainSearch = CCMenuItemImage::create("main_3.png","main_3_sel.png",   this,menu_selector(HelloWorld::menuCloseCallback));CC_BREAK_IF(! pMainSearch);CCMenuItemImage *pMainLogin = CCMenuItemImage::create("main_4.png","main_4_sel.png",   this,menu_selector(HelloWorld::menuCloseCallback));CC_BREAK_IF(! pMainLogin);CCMenuItemImage *pMainMore = CCMenuItemImage::create("main_5.png","main_5_sel.png",   this,menu_selector(HelloWorld::menuCloseCallback));CC_BREAK_IF(! pMainMore);XYMenu* pMenu = XYMenu::create(pMainHome,pMainLocation,pMainSearch,pMainLogin,pMainMore,NULL);pMenu->setPosition(CCPointZero);CC_BREAK_IF(! pMenu);this->addChild(pMenu, 2);

用到的类

XYMenu.h

#ifndef __Test2__XYMenu__#define __Test2__XYMenu__#include "cocos2d.h"USING_NS_CC;class XYMenu : public CCMenu{public:   int iCount;   XYMenu(void);   ~XYMenu(void);   void setSelectedItem(CCMenuItem *item);   bool getInit(CCArray* pArrayOfItems);      static XYMenu *create(CCMenuItem *item, ...);   static XYMenu* createWithItems(CCMenuItem *firstItem, va_list args);   static XYMenu* createWithArray(CCArray* pArrayOfItems);   virtual bool ccTouchBegan(CCTouch* touch,CCEvent* event);   virtual void ccTouchEnded(CCTouch* touch, CCEvent* event);   virtual void ccTouchCancelled(CCTouch *touch, CCEvent* event);   virtual void ccTouchMoved(CCTouch* touch, CCEvent* event);   private:   CCMenuItem *m_curHighlighted;};#endif /* defined(__Test2__XYMenu__) */
