游戏内容大概如下：

1.一个Sprite在地图上一直在跑，Sprite可以跳跃（其实是地图不断向左滚动）

2.途中有金币，Sprite吃金币，左上方的Score会++，并且会有+15的字样出现

1.创建实体类Entity，这是一个基类，主要用来绑定一个精灵，返回一个精灵

#ifndef Entity_H#define Entity_H#include "cocos2d.h"using namespace cocos2d;class Entity:public CCNode{public:    Entity();    ~Entity();    CCSprite* getSprite();    void bindSprite(CCSprite* sprite);private:    CCSprite* m_sprite;};#endif

.cpp

#include "Entity.h"Entity::Entity(){    m_sprite=NULL;}Entity::~Entity(){};CCSprite* Entity::getSprite(){    return this->m_sprite;}void Entity::bindSprite(CCSprite* sprite){    this->m_sprite=sprite;    this->addChild(m_sprite);}

<span style="font-family: 宋体; text-indent: 2em;">#ifndef _Player_H</span>

<span style="text-indent: 2em; font-family: 宋体; background-color: rgb(255, 255, 255);"></span><pre name="code" class="cpp">#define _Player_H#include "cocos2d.h"#include "Entity.h"using namespace cocos2d;#define JUMP_ACTION_TAG 1;class Player:public Entity{public:    Player();    ~Player();    CREATE_FUNC(Player);    virtual bool init();public:    void jump();    void jumpEnd();    void hit();//主角和怪物撞击（玩家受伤害）    int getMoney();    CCRect getBoundingBox();/*获取碰撞范围*/    void resetData();    void actionEnd();private:    bool m_isJumping;    int m_money;/*金钱*/};#endif

.cpp

#include "Player.h"#include "FlowWord.h"Player::Player(){    m_isJumping=false;    m_money=0;/*初始金钱为0*/}Player::~Player(){}bool Player::init(){    return true;}void Player::jump(){    if(!getSprite())    {        return;    }    if(m_isJumping)/*如果主角还在跳跃中，则不重复跳跃*/    {        return;    }    m_isJumping=true;    /*创建动作，2s，原地跳跃(即落地的地点相对于起跳地点x偏移0，y偏移0)，高度250，弹跳次数1*/    CCJumpBy* jump=CCJumpBy::create(1.5f,ccp(0,0),200,1);    /*callFunc也是一个动作，作用是调用一个函数*/    CCCallFunc* callFunc = CCCallFunc::create(this, callfunc_selector(Player::jumpEnd));    /*组合动作*/    CCActionInterval* jumpActions=CCSequence::create(jump,callFunc,NULL);    runAction(jumpActions);}void Player::jumpEnd(){    m_isJumping=false;}void Player::hit(){    if(getSprite()==NULL)    {        return;    }    /*加钱特效提示*/    FlowWord* flowword=FlowWord::create();    this->addChild(flowword);    flowword->showWord("+15",getSprite()->getPosition());    m_money+=15;    /*创建4种动作对象*/    CCMoveBy* backMove=CCMoveBy::create(0.1f,ccp(-20,0));    CCMoveBy* forwardMove=CCMoveBy::create(0.1f,ccp(20,0));    CCRotateBy* backRotate=CCRotateBy::create(0.1f,-5,0);    CCRotateBy* forwardRotate=CCRotateBy::create(0.1f,5,0);    /*分别组合成两种动作(同时执行)*/    CCSpawn* backActions=CCSpawn::create(backMove,backRotate,NULL);    CCSpawn* forwardActions=CCSpawn::create(forwardMove,forwardRotate,NULL);    CCCallFunc* callFunc=CCCallFunc::create(this,callfunc_selector(Player::actionEnd));    CCActionInterval* actions=CCSequence::create(backActions,forwardActions,callFunc,NULL);    //this->stopAllActions();    //resetData();    this->runAction(actions);}void Player::resetData(){    if(m_isJumping)    {        m_isJumping=false;    }    this->setPosition(ccp(200,500/4));    this->setScale(1.0f);    setRotation(0);}int Player::getMoney(){    return m_money;}CCRect Player::getBoundingBox(){    if(getSprite()==NULL){        return CCRectMake(0,0,0,0);    }    /*由于Sprite是放在Player上的，所以要检测Player的碰撞范围*/    CCSize spriteSize=getSprite()->getContentSize();    CCPoint entityPos=this->getPosition();//获取player中心点    //获取Player左下角的坐标值    int x=entityPos.x-spriteSize.width/2;    int y=entityPos.y-spriteSize.height/2;    return CCRectMake(x,y,spriteSize.width,spriteSize.height);}void Player::actionEnd(){    this->setScale(1.0f);    setRotation(0);}

3.创建怪物类（金币），继承于实体类

#ifndef _Monster_H_#define _Monster_H_#include "Entity.h"#include "cocos2d.h"#include "Player.h"#include "ccMacros.h"USING_NS_CC;class Monster:public Entity{public:    Monster();    ~Monster();    CREATE_FUNC(Monster);    virtual bool init();public:    void show();    void hide();    void reset();//重置怪物数据    bool isAlive();//是否活动状态    bool isCollideWithPlayer(Player* player);//检测是否碰撞private:    bool m_isAlive;};#endif

.cpp

#include "Monster.h"Monster::Monster(){}Monster::~Monster(){}bool Monster::init(){    return true;}void Monster::show(){    if(getSprite()!=NULL)    {        this->setVisible(true);        m_isAlive=true;/*标记为活动状态*/    }}void Monster::hide(){    if(getSprite()!=NULL)    {        this->setVisible(false);        reset();        m_isAlive=false;/*标记为活动状态*/    }}void Monster::reset(){    if(getSprite()!=NULL)    {        /*初始化怪物坐标,宽度(800-2800),高度（100-200）*/        this->setPosition(ccp(800+CCRANDOM_0_1()*2000,200-CCRANDOM_0_1()*100));    }}bool Monster::isAlive(){    return m_isAlive;}bool Monster::isCollideWithPlayer(Player* player){    CCRect playerRect=player->getBoundingBox();    CCPoint monsterPos=getPosition();    /*判断是否有交集*/    return playerRect.containsPoint(monsterPos);}

4.创建怪物管理器类（MonsterManger），用来管理怪物的显示和隐藏

#ifndef __MonsterManger_H__#define __MonsterManger_H__#include "cocos2d.h"#include "Player.h"USING_NS_CC;#define MAX_MONSTER_NUM 10class MonsterManger:public CCNode{public:    MonsterManger();    ~MonsterManger();    CREATE_FUNC(MonsterManger);    virtual bool init();

virtual void update(float dt);/*重写update函数*/    void bindPlayer(Player* player);private:    void createMonsters();/*创建Monster对象*/private:    CCArray* m_monsterArr;/*存放怪物数组*/    Player* m_player;};#endif

.cpp

#include "MonsterManger.h"#include "Monster.h"#define max_monster_num 20MonsterManger::MonsterManger(){}MonsterManger::~MonsterManger(){}bool MonsterManger::init(){    bool bRet=false;    do    {        createMonsters();/*创建怪物*/        this->scheduleUpdate();/*启用update*/        bRet=true;    } while (0);    return bRet;}void MonsterManger::createMonsters(){    m_monsterArr=CCArray::create();    m_monsterArr->retain();/*防止数组被释放*/    Monster* monster=NULL;    CCSprite* sprite=NULL;    for(int i=0;i<max_monster_num; i++)    {        monster=Monster::create();         monster->bindSprite(CCSprite::create("sliderThumb.png"));        monster->reset();    this->addChild(monster);  /*将怪物添加到管理器(CCNode)中*/    m_monsterArr->addObject(monster);/*添加到数组中，便于管理*/    }}void MonsterManger::update(float dt){    CCObject* obj=NULL;    Monster* monster=NULL;    CCARRAY_FOREACH(m_monsterArr,obj)/*循环遍历怪物数组，重复出现在屏幕上*/    {        monster=(Monster*) obj;        if(monster->isAlive())/*活动状态*/        {            monster->setPositionX(monster->getPositionX()-3);//左移            if(monster->getPositionX()<0)            {                monster->hide();            }else if(monster->isCollideWithPlayer(m_player)){                m_player->hit();                monster->hide();            }        }else/*非活动状态*/        {            monster->show();//        }    }}void MonsterManger::bindPlayer(Player* player){    this->m_player=player;    this->m_player->retain();//引用计数 +1}

5.创建文字飘动效果，（在主角身上显示"+15"特效）

#ifndef __FlowWord_H__#define __FlowWord_H__#include "cocos2d.h"USING_NS_CC;class FlowWord:public CCNode{public:    FlowWord();    ~FlowWord();    CREATE_FUNC(FlowWord);    virtual bool init();public:    void showWord(const char* text, CCPoint pos);    void flowEnd();private:    CCLabelTTF* m_textLab;};#endif

.cpp

#include "FlowWord.h"FlowWord::FlowWord(){}FlowWord::~FlowWord(){}bool FlowWord::init(){    m_textLab=CCLabelTTF::create("","Arial",30);    m_textLab->setColor(ccc3(255,0,0));    m_textLab->setVisible(false);    this->addChild(m_textLab);    return true;}void FlowWord::showWord(const char* str,CCPoint pos){    m_textLab->setString(str);    m_textLab->setPosition(pos);    m_textLab->setAnchorPoint(ccp(1,0));    m_textLab->setVisible(true);    //先放大后缩小    CCActionInterval* scaleLarge=CCScaleTo::create(0.3f,2.5f,2.5f);    CCActionInterval* scaleSmall=CCScaleTo::create(0.4f,0.5f,0.5f);    //回调动作，移除效果    CCCallFunc* callFunc=CCCallFunc::create(this,callfunc_selector(FlowWord::flowEnd));    CCActionInterval* actions=CCSequence::create(scaleLarge,scaleSmall,callFunc,NULL);    m_textLab->runAction(actions);}void FlowWord::flowEnd(){    m_textLab->setVisible(false);    /*true: 从父节点移除，并移除节点的动作和回调函数*/    m_textLab->removeFromParentAndCleanup(true);}

6.创建游戏场景类，所有游戏的效果都在这上面展示

#ifndef __TollgateScene_H__#define __TollgateScene_H__#include "cocos2d.h"#include "cocos-ext.h"#include "Player.h"using namespace cocos2d;using namespace cocos2d::extension;class TollgateScene : public CCLayer {public:    static CCScene* scene();    virtual bool init();    CREATE_FUNC(TollgateScene);    virtual void update(float delta);private:    void initBG();  /* 初始化关卡背景 */    void createJumpBtn();/*创建跳跃按钮*/    void jumpEvent(CCObject* pSender,CCControlEvent event);/*响应按钮点击事件*/    void createScoreLab();/*创建分数标签*/    void createTimeSlider();/*创建时间条*/private:    CCSprite* m_bgSprite1;    CCSprite* m_bgSprite2;    Player* m_player;    CCLabelTTF* m_scoreLab;//分数标签    CCControlSlider* m_TimeSlider;//时间条    int m_score;    /*得分*/    int m_curTime; /*当前时间*/};#endif

.cpp

#include "TollgateScene.h"#include "MonsterManger.h"CCScene* TollgateScene::scene() {    CCScene* scene = NULL;    do    {        scene = CCScene::create();        CC_BREAK_IF(!scene);        TollgateScene* layer = TollgateScene::create();        CC_BREAK_IF(!layer);        scene->addChild(layer, 1);    } while (0);    return scene;}bool TollgateScene::init() {    bool bRet = false;    do    {        CCSize visibleSize = CCDirector::sharedDirector()->getVisibleSize();        /*游戏标题图片*/        //      CCSprite* titleSprite = CCSprite::create("title.png");        //      titleSprite->setPosition(ccp(visibleSize.width / 2, visibleSize.height - 50));        //      this->addChild(titleSprite, 2);        /*创建猪脚*/        CCSprite* sprite = CCSprite::create("sprite.png");        //sprite->setFlipX(true);        m_player = Player::create();        m_player->bindSprite(sprite);        m_player->setPosition(ccp(200, visibleSize.height / 4));        this->addChild(m_player,1);        /*初始化背景图片*/        initBG();        /*创建按钮*/        createJumpBtn();        /*设置启用CCNode的update()函数,游戏会在每一帧调用update()函数*/        this->scheduleUpdate();        /*创建怪物管理器(管理器里面放了很多怪物)*/        MonsterManger* monsterManger=MonsterManger::create();        monsterManger->bindPlayer(m_player);        this->addChild(monsterManger,4);        /*创建分数标签*/        createScoreLab();        /*创建时间条*/        createTimeSlider();        bRet = true;    } while (0);    return bRet;}void TollgateScene::initBG() {    CCSize visibleSize = CCDirector::sharedDirector()->getVisibleSize();    m_bgSprite1 = CCSprite::create("HelloWorld.png");    m_bgSprite1->setPosition(ccp(visibleSize.width / 2, visibleSize.height / 2));    this->addChild(m_bgSprite1, 0);    m_bgSprite2 = CCSprite::create("HelloWorld.png");    m_bgSprite2->setPosition(ccp(visibleSize.width + visibleSize.width / 2, visibleSize.height / 2));    m_bgSprite2->setFlipX(true);    this->addChild(m_bgSprite2, 0);}void TollgateScene::update(float delta){    CCSize mapSize=m_bgSprite1->getContentSize();//地图大小    int posX1=m_bgSprite1->getPositionX();  //地图1的x坐标    int posX2=m_bgSprite2->getPositionX();   //地图2的x坐标    int iSpeed = 2; //地图滚动的速度    posX1-=iSpeed;  //两张地图一起向左滚动    posX2-=iSpeed;    //创建无限循环    if(posX1<=-mapSize.width/2)    {        posX1=mapSize.width+mapSize.width/2;        posX2=mapSize.width/2;    }    if(posX2<=-mapSize.width/2)    {        posX1=mapSize.width/2;        posX2=mapSize.width+mapSize.width/2;    }    m_bgSprite1->setPositionX(posX1);    m_bgSprite2->setPositionX(posX2);    /*分数增加*/    m_score=m_player->getMoney();    m_scoreLab->setString(CCString::createWithFormat("Score:%d",m_score)->getCString());    m_TimeSlider->setValue(--m_curTime);}void TollgateScene::createJumpBtn(){    CCSize visibleSize=CCDirector::sharedDirector()->getVisibleSize();    /*按钮标题*/    CCLabelTTF* jumpLabel=CCLabelTTF::create("Jump","Arial",35);    /*按钮状态图片*/    CCScale9Sprite* jumpNorBG=CCScale9Sprite::create("CloseNormal.png");    CCScale9Sprite* jumpLightBG=CCScale9Sprite::create("CloseSelected.png");    /*创建按钮*/    CCControlButton* jumpBtn=CCControlButton::create(jumpLabel,jumpNorBG);    jumpBtn->setPosition(ccp(visibleSize.width-80,50));    jumpBtn->setBackgroundSpriteForState(jumpLightBG,CCControlStateHighlighted);    /*添加事件*/    jumpBtn->addTargetWithActionForControlEvents(this,        cccontrol_selector(TollgateScene::jumpEvent),        CCControlEventTouchDown);    this->addChild(jumpBtn);}void TollgateScene::jumpEvent(CCObject* pSender,CCControlEvent event){    m_player->jump();}void TollgateScene::createScoreLab(){    m_score=m_player->getMoney();    CCSize visibleSize=CCDirector::sharedDirector()->getVisibleSize();    m_scoreLab=CCLabelTTF::create("Score:"+m_score,"Arial",35);    m_scoreLab->setAnchorPoint(ccp(0,1));    m_scoreLab->setPosition(ccp(0,visibleSize.height));    this->addChild(m_scoreLab);}void TollgateScene::createTimeSlider(){    CCSize visibleSize=CCDirector::sharedDirector()->getVisibleSize();    m_curTime=10000;    m_TimeSlider=CCControlSlider::create(        CCSprite::create("sliderProgress.png"),        CCSprite::create("sliderProgress2.png"),        CCSprite::create("sliderThumb.png")        );    m_TimeSlider->setPosition(ccp(        m_TimeSlider->getContentSize().width/2,        visibleSize.height-m_TimeSlider->getContentSize().height-m_scoreLab->getContentSize().height        ));    m_TimeSlider->setTouchEnabled(false);    m_TimeSlider->setMaximumValue(10000);    m_TimeSlider->setMinimumValue(0);    m_TimeSlider->setValue(m_curTime);    this->addChild(m_TimeSlider,3);}

运行效果如下:
