Cocos2dx: Replacing a Scene

In HelloWorld.h:

class HelloWorld : public cocos2d::Layer

{

public:

    

    static cocos2d::Scene* createScene();

    virtual bool init();

    

    CREATE_FUNC(HelloWorld);

    

    void Play(Ref *pSender);   

};

In HelloWorld.cpp:

#include "NewScene.h"

bool HelloWorld::init()

{

    if ( !Layer::init() )

    {

        return false;

    }

    

    

    auto menu_item_1 = MenuItemFont::create("Play", CC_CALLBACK_1(HelloWorld::Play, this));

    

    

    auto *menu = Menu::create(menu_item_1,NULL);

    menu->alignItemsVerticallyWithPadding(40);

    this->addChild(menu);

    

    return true;

}

void HelloWorld::Play(cocos2d::Ref *pSender){

    CCLOG("Play");

    auto scene = NewScene::createScene();

    Director::getInstance()->replaceScene(scene);

}

In NewScene.h:

class NewScene : public cocos2d::Layer

{

public:

    static cocos2d::Scene* createScene();

    virtual bool init();

    

    CREATE_FUNC(NewScene);

    

    

    void GoBack(Ref *pSender);

   

};

In NewScene.cpp:

#include "HelloWorldScene.h"

bool NewScene::init()

{

    

    if ( !Layer::init() )

    {

        return false;

    }

    

    auto menu_item_1 = MenuItemFont::create("Go Back", CC_CALLBACK_1(NewScene::GoBack, this));

   

    

    auto *menu = Menu::create(menu_item_1,NULL);

    menu->alignItemsVerticallyWithPadding(40);

    this->addChild(menu);

   

    

    return true;

}

void NewScene::GoBack(cocos2d::Ref *pSender){
