cocos2dx3.2开发 RPG《Flighting》（十四）暂停按钮

Cocos2d-x
#1

一、前言
整个教程快接近尾声了。还有一个暂停功能需要添加
二、正文
首先，我们要在右上方添加一个按钮

bool FlightLayer::init(){  
      
    MenuItemImage* pauseBtnItem = MenuItemImage::create("UI/pauseBtn.png","UI/pauseBtn.png",=](Ref* pSender){Director::getInstance()->pushScene(PauseScene::create());});  
    Menu* pauseBtn = Menu::create(pauseBtnItem,NULL);  
    pauseBtn->setPosition(1180,650);  
    this->addChild(pauseBtn,4);  
  
      
  
    return true;  
}  

```

这个按钮很简单，回到函数也直接用lumada表达式了


点击的时候会弹出PuaseScene

class PauseScene : public Scene{  
public:  
    virtual bool init();  
    CREATE_FUNC(PauseScene);  
private:  
    void continueGame(Ref* pSender,TouchEventType type);  
    void stopGame(Ref* pSender,TouchEventType type);  
};  

```



#include "PauseScene.h"  
  
bool PauseScene::init(){  
    Widget* pNode = GUIReader::getInstance()->widgetFromJsonFile("UI/PauseUI.json");  
    this->addChild(pNode,0);  
  
    Button* continueBtn = (Button*)Helper::seekWidgetByName(pNode,"continueBtn");  
    continueBtn->addTouchEventListener(this,toucheventselector(PauseScene::continueGame));  
    Button* stopBtn = (Button*)Helper::seekWidgetByName(pNode,"stopBtn");  
    stopBtn->addTouchEventListener(this,toucheventselector(PauseScene::stopGame));  
    return true;  
}  
  
void PauseScene::continueGame(Ref* pSender,TouchEventType type){  
    if(type == TouchEventType::TOUCH_EVENT_BEGAN){  
        CCLOG("GAME CONTINUE");  
        Director::getInstance()->popScene();  
    }  
}  
  
void PauseScene::stopGame(Ref* pSender,TouchEventType type){  
    if(type == TouchEventType::TOUCH_EVENT_BEGAN){  
        CCLOG("GAME STOP");  
        Director::getInstance()->replaceScene(ChooseScene::create());  
    }  
}  

```

大概就这样吧。
