Cocos2d-x之LayerMultiplex的使用

概述1、用处 用于管理Layer的切换，而不用切换场景。 2、代码 1）.h文件 #include "cocos2d.h"#include "ui/CocosGUI.h"#include "VisibleRect.h"USING_NS_CC;using namespace ui;class LayerMultiplexDemo : public Scene{public: CR 1、用处

用于管理Layer的切换，而不用切换场景。

2、代码 1）.h文件

#include "cocos2d.h"#include "ui/CocosGUI.h"#include "VisibleRect.h"USING_NS_CC;using namespace ui;class LayerMultiplexDemo : public Scene{public:    CREATE_FUNC(LayerMultiplexDemo);    virtual bool init();};class BaseLayer : public Layer{public:    CREATE_FUNC(BaseLayer);    virtual bool init();    Text* text;    Size winSize;};class MainLayer : public BaseLayer{public:    CREATE_FUNC(MainLayer);    virtual bool init();    voID menuCallback1(Ref* sender);    voID menuCallback2(Ref* sender);    voID menuCallback3(Ref* sender);};class Layer1 : public BaseLayer{public:    CREATE_FUNC(Layer1);    virtual bool init();    voID touchEvent(cocos2d::Ref *pSender,cocos2d::ui::Widget::touchEventType type);};class Layer2 : public BaseLayer{public:    CREATE_FUNC(Layer2);    virtual bool init();    voID touchEvent(cocos2d::Ref *pSender,cocos2d::ui::Widget::touchEventType type);};class Layer3 : public BaseLayer{public:    CREATE_FUNC(Layer3);    virtual bool init();    voID touchEvent(cocos2d::Ref *pSender,cocos2d::ui::Widget::touchEventType type);};
