I am a real beginner of cocos2d from Taiwan and just started learning 3 days ago. My OS is win 8.1 and my IDE is visual studio. In the tutorial about adding a menu font item, I tried to implement the same menu font step by step but failed.

This is my HelloWorldScene.cpp.

#include "HelloWorldScene.h"
#include "ui/CocosGUI.h"
#include "SimpleAudioEngine.h"


USING_NS_CC;

Scene* HelloWorld::createScene()
{
    // 'scene' is an autorelease object
    auto scene = Scene::create();
    
    // 'layer' is an autorelease object
    auto layer = HelloWorld::create();

    // add layer as a child to scene
    scene->addChild(layer);

    // return the scene
    return scene;
}

// on "init" you need to initialize your instance
bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }
    
    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

    /////////////////////////////
    // 2. add a menu item with "X" image, which is clicked to quit the program
    //    you may modify it.

    // add a "close" icon to exit the progress. it's an autorelease object
    auto closeItem = MenuItemImage::create(
                                           "CloseNormal.png",
                                           "CloseSelected.png",
                                           CC_CALLBACK_1(HelloWorld::menuCloseCallback, this));
    
	closeItem->setPosition(Vec2(origin.x + visibleSize.width - closeItem->getContentSize().width/2 ,
                                origin.y + closeItem->getContentSize().height/2));

    // create menu, it's an autorelease object
    auto menu = Menu::create(closeItem, NULL);
    menu->setPosition(Vec2::ZERO);
    this->addChild(menu, 1);

    /////////////////////////////
    // 3. add your codes below...

    // add a label shows "Hello World"
    // create and initialize a label
    
    auto label = Label::createWithTTF("My First New Game!", "fonts/Marker Felt.ttf", 72);
    
    // position the label on the center of the screen
    label->setPosition(Vec2(origin.x + visibleSize.width/2,
                            origin.y + visibleSize.height - label->getContentSize().height));

    // add the label as a child to this layer
    this->addChild(label, 1);
	
	label->enableOutline(Color4B::BLUE, 1);

    // add "HelloWorld" splash screen"
    //auto sprite = Sprite::create("HelloWorld.png");
	auto elfsprite = Sprite::create("ne.png");

	elfsprite->setPosition(Vec2(visibleSize.width / 2 + origin.x + 100, visibleSize.height / 2 + origin.y));

	this->addChild(elfsprite, 3);

	auto menu_item_1 = MenuItemFont::create("Play", CC_CALLBACK_1(HelloWorld::Play,this));
	auto menu_item_2 = MenuItemFont::create("Highscores", CC_CALLBACK_1(HelloWorld::HighScores, this));
	auto menu_item_3 = MenuItemFont::create("Settings", CC_CALLBACK_1(HelloWorld::Settings, this));

	menu_item_1->setPosition(Vec2(visibleSize.width / 2,	(visibleSize / 4) * 3));
	menu_item_2->setPosition(Point(visibleSize.width / 2, (visibleSize / 4) * 2));
	menu_item_3->setPosition(Point(visibleSize.width / 2, (visibleSize / 4) * 1));

	auto *menu = Menu::create(menu_item_1, menu_item_2, menu_item_3, nullptr);

	return true;
}

void HelloWorld::Play(cocos2d::Ref *pSender)
{
	CCLOG("Play");
}

void HelloWorld::HighScores(cocos2d::Ref *pSender)
{
	CCLOG("HighScores");
}
void HelloWorld::Settings(cocos2d::Ref *pSender)
{
	CCLOG("Settings");
}

void HelloWorld::menuCloseCallback(Ref* pSender)
{ 
    Director::getInstance()->end();

#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
    exit(0);
#endif
}

And  this is my HelloWorldScene.h

#ifndef __HELLOWORLD_SCENE_H__
#define __HELLOWORLD_SCENE_H__

#include "cocos2d.h"

class HelloWorld : public cocos2d::Layer
{
public:
    // there's no 'id' in cpp, so we recommend returning the class instance pointer
    static cocos2d::Scene* createScene();

    // Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone
    virtual bool init();
    
    // a selector callback
    void menuCloseCallback(cocos2d::Ref* pSender);
    
    // implement the "static create()" method manually
    CREATE_FUNC(HelloWorld);

	//adding function, try to move my sprite
	//bool onTouchBegan(cocos2d::Touch *touch, cocos2d::Event *event);
	//void onTouchMoved(cocos2d::Touch *touch, cocos2d::Event *event);
	//void onTouchEnded(cocos2d::Touch *touch, cocos2d::Event *event);

	void Play(Ref *pSender);
	void HighScores(Ref *pSender);
	void Settings(Ref *pSender);

};

#endif // __HELLOWORLD_SCENE_H__

I received an error message about both Vec2 and Point Part.
