Comprehensive application of menu in Cocos2d-X

Today, the code and project previously written are integrated into a menu. You can switch to the previous project through the menu.

Project directory of the program

Main code analysis:

Create a menu in lessonmenu. H, traverse the menu, and switch to each project through the menu

# Ifndef _ lessonmenu_h _ # DEFINE _ lessonmenu_h _ # include "cocos2d. H "using_ns_cc; Class lessonmenu: Public cclayer {public: bool Init (); static ccscene * scene (); void enterlasson (ccobject * sender ); // process the touch event bool cctouchbegan (cctouch *, ccevent); void cctouchmoved (cctouch *, ccevent *); create_func (lessonmenu) ;};# endif

Layerback. h creates a layer with only one return button. Use the return button to implement scenario switching.

#ifndef _LayerBack_H_#define _LayerBack_H_#include "cocos2d.h"USING_NS_CC;class LayerBack : public CCLayer{public:    bool init();    void back(CCObject*);};#endif

The specific implementation code in layerback. cpp

# Include "layerback. H "bool layerback: Init () {cclayer: Init (); // obtain the window size. ccsize winsize = ccdirector: shareddire()-> getwinsize (); ccmenu * menu = ccmenu: Create (); addchild (menu); ccmenuitem * backitem = shortcut: Create ("closenormal.png", "closeselected.png", this, menu_selector (layerback :: back); menu-> addchild (backitem); // set the position of the menu item (set the menu item to the bottom right corner) backitem-> setposition (CCP (winsize. width/2-backitem-> getcontentsize (). width/2, backitem-> getcontentsize (). height/2-winsize. height/2); Return true;} void layerback: Back (ccobject *) {// scenario switch ccdirector: shareddirector ()-> popscene ();}

Execution result:
