快过节了,谢谢了屈原,我们爱你。

应该多几个向屈大人一样跳江的,这样我们就可以放假纪念啦。

---------------------------------快过节了,弄个案例,大家不妨假期做做,

运行效果展示:

bubuko.com,布布扣

bubuko.com,布布扣

全部代码和资源:

http://download.csdn.net/detail/sdhjob/7424329

1.准备资源

背景图片menuback.png:

bubuko.com,布布扣

节点图片

greenstar.png  bubuko.com,布布扣 

redstar.png     bubuko.com,布布扣 

yellowstar.png bubuko.com,布布扣

2.创建一个新项目(如何配置环境和创建新项目,参考前面教程):

cocos new -p com.xdl.game -l cpp -d ~/Desktop/test0515 snamegame

3.添加文件

首先将HelloWoldScene.h HelloWorld.cpp移走,然后添加GameScene.h GameScene.cpp HelpScene.h HelpScene.cpp MainMenu.h MainMenu.cpp

加上原来自动生成的AppDelegate.h 和AppDelegate.cpp共8个文件

4.编码

AppDelegate.h (这个文件基本没改动)

#ifndef  _APP_DELEGATE_H_

#define  _APP_DELEGATE_H_

#include "cocos2d.h"

class  AppDelegate : private cocos2d::Application

{

public:

    AppDelegate();

    virtual ~AppDelegate();

    virtual bool applicationDidFinishLaunching();

    virtual void applicationDidEnterBackground();

    virtual void applicationWillEnterForeground();

};

#endif // _APP_DELEGATE_H_

AppDelegate.cpp 

#include "AppDelegate.h"

#include "MainMenu.h"

#include "SimpleAudioEngine.h"    

USING_NS_CC;

using namespace CocosDenshion;

AppDelegate::AppDelegate() {

}

AppDelegate::~AppDelegate() 

{

}

bool AppDelegate::applicationDidFinishLaunching() {

    // initialize director

    auto director = Director::getInstance();

    auto glview = director->getOpenGLView();

    if(!glview) {

        glview = GLView::create("My Game");

        director->setOpenGLView(glview);

    }

    // turn on display FPS

    director->setDisplayStats(false);

    // set FPS. the default value is 1.0/60 if you don‘t call this

    director->setAnimationInterval(1.0 / 60);

    // create a scene. it‘s an autorelease object

    auto scene = MainMenu::createScene();

    // run

    director->runWithScene(scene);

    //开始播放背景音乐

    SimpleAudioEngine::getInstance()->playBackgroundMusic("background.mp3");

    return true;

}


// This function will be called when the app is inactive. When comes a phone call,it‘s be invoked too

void AppDelegate::applicationDidEnterBackground() {

    Director::getInstance()->stopAnimation();

    // if you use SimpleAudioEngine, it must be pause

    SimpleAudioEngine::getInstance()->pauseBackgroundMusic();

}


// this function will be called when the app is active again

void AppDelegate::applicationWillEnterForeground() {

    Director::getInstance()->startAnimation();

    // if you use SimpleAudioEngine, it must resume here

    SimpleAudioEngine::getInstance()->resumeBackgroundMusic();

}

说明: 在入口类中加入了背景音乐的播放,并且入口场景设计为MainMenu,往下看

MainMenu.h

#ifndef __snakegame__MainMenu__

#define __snakegame__MainMenu__

#include "cocos2d.h"

USING_NS_CC;

class MainMenu:public Layer{

public:

    static Scene * createScene();

    CREATE_FUNC(MainMenu);

    virtual bool init();

    void menuCallBack(Ref * object);

};

#endif


MainMenu.cpp

#include "MainMenu.h"

#include "GameScene.h"

#include "HelpScene.h"

Scene * MainMenu::createScene()

{   auto scene=Scene::create();

    auto layer=MainMenu::create();

    scene->addChild(layer);

    return scene;

}

 bool MainMenu::init(){

     if(!Layer::init())

    {

    return false;

    }

     auto size=Director::getInstance()->getWinSize();

     //添加背景

     auto spriteBK=Sprite::create("menuback.png");

     spriteBK->setPosition(Point(size.width/2,size.height/2));

     this->addChild(spriteBK);

     //添加2个菜单条目

     auto menuItemStart=MenuItemFont::create("Start", CC_CALLBACK_1(MainMenu::menuCallBack,this));

     menuItemStart->setTag(1);

     auto menuItemHelp=MenuItemFont::create("Help", CC_CALLBACK_1(MainMenu::menuCallBack,this));

     menuItemHelp->setTag(2);

     auto menu=Menu::create(menuItemStart,menuItemHelp,NULL);

     menu->setPosition(Point::ZERO);

     menuItemStart->setPosition(Point(size.width-menuItemStart->getContentSize().width-100,menuItemStart->getContentSize().height+10));

     menuItemHelp->setPosition(Point(size.width-menuItemHelp->getContentSize().width-10,menuItemHelp->getContentSize().height+10));

     this->addChild(menu);

     return true;

}

void MainMenu::menuCallBack(Ref * object){

    auto target=(Node *)object;

    Scene * scene;

    switch (target->getTag()) {

        case 1://startgame

            scene=Game::createScene();

            break;

        case 2://Helpgame

            scene=Help::createScene();

            break;

        default:

            break;

    }

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

  }

说明:在菜单场景中实现了跳转到帮助场景和游戏场景,往下看:

HelpScene.h

#ifndef __snakegame__HelpScene__

#define __snakegame__HelpScene__

#include "cocos2d.h"

USING_NS_CC;

class Help:public Layer{

public:

    static Scene * createScene();

    CREATE_FUNC(Help);

    virtual bool init();

    void menuCallBack(Ref * object);

};

#endif

HelpScene.cpp

#include "HelpScene.h"

#include "MainMenu.h"

Scene * Help::createScene(){

    auto scene=Scene::create();

    auto layer=Help::create();

    scene->addChild(layer);

    return scene;

   }

bool  Help::init(){

    if(!Layer::init())

        {

        return  false;

        }

      auto size=Director::getInstance()->getWinSize();

    //添加背景

    auto spriteBK=Sprite::create("menuback.png");

    spriteBK->setPosition(Point(size.width/2,size.height/2));

    spriteBK->setOpacity(75);

    this->addChild(spriteBK);

    //帮助信息

    auto labelScore=Label::create("帮助信息", "宋体", 25);

    labelScore->setPosition(Point(size.width-80,size.height-50));

    this->addChild(labelScore);

    //返回按钮

    auto menuItemBack=MenuItemFont::create("Back", CC_CALLBACK_1(Help::menuCallBack,this));

    auto menu=Menu::create(menuItemBack,NULL);

    menu->setPosition(Point::ZERO);

    menuItemBack->setPosition(Point(size.width-menuItemBack->getContentSize().width-100,menuItemBack->getContentSize().height+10));

    this->addChild(menu);

    return true;

}

void  Help::menuCallBack(Ref * object){

    auto scene=MainMenu::createScene();

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

}

说明:这里只是实现了一个帮助信息显示,可以返回到菜单,下面看游戏场景

GameScene.h

#ifndef __snakegame__GameScene__

#define __snakegame__GameScene__

#include "cocos2d.h"

USING_NS_CC;

enum class ENUM_DIR{

    DIR_UP,

    DIR_DOWN,
