cocs2d的开发环境我相信大家都能搭建好了，下面我们直接的进入正题，开始做我们的小游戏，如果对搭建环境还有不懂的童鞋请看我写的这篇博文

cocos2d-x 3.0游戏开发xcode5帅印博客教学 001.[HoldTail]环境的搭建以及项目创建

首先我们来看看主画面和关卡选择画面的背景图片

我这里就不上传过多的图片了，直接进入正题看我们的第一个画面如何实现

图片我们是用的原来的官方团对的美术图片在这里大家都要感谢一下官方团体能做出这么美丽的图片（广科院移动应用开发中心）

我这里就不上传过多的图片了，直接进入正题看我们的第一个画面如何实现

主画面由HelloWorldScene.h和HelloWorldScene.cpp构成

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(Object* pSender);

    // implement the "static create()" method manually
    CREATE_FUNC(HelloWorld);
};
#endif // __HELLOWORLD_SCENE_H__

HelloWorldScene.cpp

#include "HelloWorldScene.h"
#include "ScrollViewScene.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();
    Point origin = Director::getInstance()->getVisibleOrigin();
    /////////////////////////////
    // 2. add a menu item with "X" image, which is clicked to quit the program
    //    you may modify it.

    //加入背景
    Size size = CCDirector::getInstance()->getWinSize();
    SpriteFrameCache *cache = SpriteFrameCache::getInstance();
    cache->addSpriteFramesWithFile("UIResoure.plist");

    Sprite* sprite =Sprite::createWithSpriteFrameName("start-bg.png");
    sprite->setPosition(Point(size.width*0.5+100,size.height*0.5));
    addChild(sprite);

    // add a "close" icon to exit the progress. it's an autorelease object
//    auto closeItem = MenuItemImage::create(
//                                           "UIResoure_play.png",
//                                           "UIResoure_plays.png",
//                                           CC_CALLBACK_1(HelloWorld::menuCloseCallback, this));
//    closeItem->setPosition(Point(size.width*0.5,size.height*0.5-100));
//
//    // create menu, it's an autorelease object
//    auto menu = Menu::create(closeItem, NULL);
//    menu->setPosition(Point::ZERO);
//    this->addChild(menu, 1);

    MenuItemImage *closeItem = MenuItemImage::create();
    closeItem->setNormalSpriteFrame(cache->spriteFrameByName("play-1.png"));
    closeItem->setSelectedSpriteFrame(cache->spriteFrameByName("play-2.png"));
    closeItem->initWithTarget(this, menu_selector(HelloWorld::menuCloseCallback));
    closeItem->setPosition(Point(size.width*0.5,size.height*0.5-100));
    auto menu = Menu::create(closeItem, NULL);
    menu->setPosition(Point::ZERO);
    this->addChild(menu, 1);

    return true;
}

void HelloWorld::menuCloseCallback(Object* pSender)
{
    //Director::getInstance()->end();
    //实现
    CCDirector::getInstance()->replaceScene(CCTransitionFade::create(0.5, ScrollViewScene::create()));

    //释放没有用到过的缓冲
    //CCTextureCache::sharedTextureCache()->removeUnusedTextures();
//#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
//    exit(0);
//#endif
}

这样主画面就做好了，下面进入关卡选择画面的制作，关卡选择画面的制作要比想像中的复杂，首先我们要建立一个场景类

    return bRet;
}
void ScrollViewScene::menuCloseCallback(Object* pSender){
    CCDirector::getInstance()->replaceScene(CCTransitionFade::create(0.5, HelloWorld::createScene()));
}

建立完成场景类之后，我们要建立我们的场景工具类，这个类可以帮助我们实现左右滑动的效果，这是一个非常用的工具类哦，非常值得大家的学习哦。

这样下来只要你自己再写6个这样的类，我们的游戏主画面跟场景就算是做好了，大家一起加油把。

这里我强调一下由于是用的官方团队的原图片，源码我就暂时不公布出来，如果大家想要，我会联系官方团队后再开源出来，方便大家学习。
