### 开始界面 ###

#ifndef SCENESTART_H
    #define SCENESTART_H
    #include "cocos2d.h"
    #include "SceneGame.h"
    USING_NS_CC;
    
    class SceneStart : public CCLayer
    {
    public:
        //SceneStart();
    
       static CCScene * scene();
       CREATE_FUNC(SceneStart)
       bool init();
    
        bool ccTouchBegan(CCTouch *pTouch, CCEvent *pEvent);
        void ccTouchEnded(CCTouch *pTouch, CCEvent *pEvent);
        void update(float delta);
    
        CCSprite *_red;
        CCSprite *_black;
        bool _selected;
    
    };
    
    #endif // SCENESTART_H

开始界面实现了滚动布局与点击选择执黑还是执白的功能。

### 放置棋盘与桌面 ###

//desk
        CCSprite *desk=CCSprite::create("floor.jpg");
        addChild(desk);
        desk->setPosition(ccp(winSize.width/2,winSize.height/2));
        desk->setScaleX(winSize.width/desk->getContentSize().width);
        desk->setScaleY(winSize.height/desk->getContentSize().height);
    
        //add plate and  stone
    
        CCSprite *plate=CCSprite::create("background.png");
        plate->setAnchorPoint(ccp(0,0));
        plate->setPosition(_plateoffset);
        plate->setScale((winSize.height-_plateoffset.y*2)/plate->getContentSize().height);
        addChild(plate);

### 创建棋子类 ###

#ifndef STONE_H
    #define STONE_H
    #include "cocos2d.h"
    USING_NS_CC;
    
    class Stone : public CCSprite
    {
    public:
        Stone();
        enum TYPE {JIANG,SHI,XIANG,CHE,MA,PAO,BING};
        static Stone *create(int id,bool red)
        {
            Stone *s=new Stone();
            s->init(id,red);
            s->autorelease();
            return s;
        }
       void reset(bool red);
    
       bool init(int id,bool red)
       {
           _id=id;
           _red=_id<16;
           //once init
           if(_id < 16)
             _type = _initPos[_id]._type;
             else
            _type = _initPos[_id-16]._type;
           const char* stonePic[14] = {
                       "rshuai.png",
                       "rshi.png",
                       "rxiang.png",

                       "rma.png",
                       "rpao.png",
                       "rbing.png",
    
                       "bjiang.png",

                       "bxiang.png",
                       "bche.png",
                       "bma.png",
                       "bpao.png",
                       "bzu.png"
                   };
           int idx=(_red?0:1)*7+_type;
           CCSprite::initWithFile(stonePic[idx]);
           setScale(.8f);
           reset(red);
           return true;
       }
    
        CC_SYNTHESIZE(TYPE,_type,Type)
        CC_SYNTHESIZE(int,_x,X)
        CC_SYNTHESIZE(int,_y,Y)
        CC_SYNTHESIZE(int,_id,Id)
        CC_SYNTHESIZE(bool,_dead,Dead)
        CC_SYNTHESIZE(bool,_red,Red)
    
        static struct InitPos
        {
            int _x;
            int _y;
            Stone::TYPE _type;
        }_initPos[16];
    
    };
    
    #endif // STONE_H

### 加载棋子类，世界坐标与棋盘坐标的转换 ###

//addstone
        for(int i=0;i<32;i++)
        {
            _s[i]=Stone::create(i,red);
            addChild(_s[i]);
            //_s[i]->setPosition(ccp(_s[i]->getX()*_d,_s[i]->getY()*_d)+_stoneoffset);
            //setRealPos(_s[i]);
            _s[i]->setPosition(ccp(CCRANDOM_0_1()*winSize.width,CCRANDOM_0_1()*winSize.height));
    
            CCMoveTo* move=CCMoveTo::create(1,this->getStonePos(_s[i]->getX(), _s[i]->getY()));
            _s[i]->runAction(move);
        }

### 加载悔棋按钮 ###

CCMenu *menu=CCMenu::create();
        CCMenuItemImage *item=CCMenuItemImage::create("regret.jpg","regret.jpg",this,menu_selector(SceneGame::back));
        menu->addChild(item);
        addChild(menu);
        menu->setPositionX(menu->getPositionX()+200);
        _steps=CCArray::create();
        _steps->retain();

### 悔棋功能的实现 ###

void SceneGame::back(CCObject *)
    {
        //CCLog("HELLO WORLD\n");
        if(_steps->count()==0)
            return;
        Step *step=(Step*)_steps->lastObject();
        _s[step->_moveid]->setX(step->_xFrom);
        _s[step->_moveid]->setY(step->_yFrom);
        _s[step->_moveid]->setPosition(getStonePos(step->_xFrom,step->_yFrom));
        if(step->_killid!=-1)
        {
            _s[step->_killid]->setVisible(true);
            _s[step->_killid]->setDead(false);
        }
    
        _redTrun=!_redTrun;
        _steps->removeLastObject();
    
    }
