游戏地图：

init()函数初始化游戏地图

    map = new GameObjMap();    map->setAnchorPoint(ccp(0,1));    map->setPosition(ccp(0,size.height));    addChild(map,0);

进入GameObjMap类ccp文件，地图初始化过程
雾和山水图组成一张游戏背景，创建2张

    CCSprite *bg1 = CCSprite::create("back_1.png");//雾    bg1->setScale(0.5);    bg1->setAnchorPoint(ccp(0,1));    bg1->setPosition(ccp(0, size.height) );    this->addChild(bg1,0,0);    CCSprite *bgdi1 = CCSprite::create("back_5.png"); //山水    bgdi1->setAnchorPoint(ccp(0,0));    bgdi1->setPosition(ccp(0,-124) );    bg1->addChild(bgdi1,1);    CCSprite *bg2 = CCSprite::create("back_1.png");    bg2->setScale(0.5);    bg2->setAnchorPoint(ccp(0,1));    bg2->setPosition(ccp(size.width, size.height) );    this->addChild(bg2,0,1);    CCSprite *bgdi2 = CCSprite::create("back_5.png");    bgdi2->setAnchorPoint(ccp(0,0));    bgdi2->setPosition(ccp(0,-124) );    bg2->addChild(bgdi2,1);

两张图滚动效果

    bg1->runAction(CCSequence::create(CCMoveBy::create(10,ccp(-480,0)),CCCallFuncN::create(this, callfuncN_selector(GameObjMap::bg1change)),NULL));//第1张先往左移动    bg2->runAction(CCSequence::create(CCMoveBy::create(20,ccp(-960,0)),CCCallFuncN::create(this, callfuncN_selector(GameObjMap::bg2change)),NULL));//第2张跟上，这样避免出现黑框 //移出屏幕重设位置，继续左移，无限循环void GameObjMap::bg1change(CCNode* pSender){    CCSprite *bg = (CCSprite *)this->getChildByTag(0);    bg->setPosition(ccp(480,320));    bg->runAction(CCSequence::create(CCMoveBy::create(20,ccp(-960,0)),CCCallFuncN::create(this, callfuncN_selector(GameObjMap::bg1change)),NULL));    for(int i = 0;i < 5;i ++){//显示星星        ((GameObjStar *)stars1->objectAtIndex(i))->set_visable(true);    }}//移出屏幕重设位置，继续左移，无限循环void GameObjMap::bg2change(CCNode* pSender){    CCSprite *bg = (CCSprite *)this->getChildByTag(1);    bg->setPosition(ccp(480,320));    bg->runAction(CCSequence::create(CCMoveBy::create(20,ccp(-960,0)),CCCallFuncN::create(this, callfuncN_selector(GameObjMap::bg2change)),NULL));    for(int i = 0;i < 5;i ++){        ((GameObjStar *)stars2->objectAtIndex(i))->set_visable(true);    }}

在地图上添加星星

stars1 = CCArray::createWithCapacity(5);    stars2 = CCArray::createWithCapacity(5);    for(int i = 0;i < 5;i ++){        GameObjStar *obj = new GameObjStar();        obj->setPosition(ccp(172 + 192 * i,350));        stars1->addObject(obj);        bg1->addChild(obj,3);        obj = new GameObjStar();        obj->setPosition(ccp(172 + 192 * i,350));        stars2->addObject(obj);        bg2->addChild(obj,3);    }    stars1->retain();    stars2->retain();

在地图上添加林木、植物、道路,至此地图初始化完毕

for(int i = 0;i < 7;i ++){        CCSprite *roaddi;        CCSprite *plant;        if(bg1shu[i] != -1){           CCSprite *road;           switch(bg1shu[i]){            case 0:                plant = CCSprite::create("back_2.png");                plant->setAnchorPoint(ccp(0.5,0));                plant->setPosition( ccp(128 * i + 64,117) );                bg1->addChild(plant,1);                road = CCSprite::create("road_2.png");                road->setAnchorPoint(ccp(0,0));                road->setPosition( ccp(128 * i,0) );                roaddi = CCSprite::create("road_3.png");                roaddi->setAnchorPoint(ccp(0,1));                roaddi->setPosition( ccp(128 * i,0) );                bg1->addChild(roaddi,1);                break;            case 1:                road = CCSprite::create("road_1.png");                road->setAnchorPoint(ccp(0,0));                road->setPosition( ccp(26 + 128 * i,0) );                roaddi = CCSprite::create("road_4.png");                                roaddi->setAnchorPoint(ccp(0,1));                roaddi->setPosition( ccp(26 + 128 * i,0) );                bg1->addChild(roaddi,1);                break;            case 2:                plant = CCSprite::create("enemy.png");                plant->setAnchorPoint(ccp(0.5,0));                plant->setPosition( ccp(128 * i + 64,112) );                bg1->addChild(plant,1);                road = CCSprite::create("road_1.png");                road->setFlipX(true);                road->setAnchorPoint(ccp(0,0));                road->setPosition( ccp(128 * i,0) );                roaddi = CCSprite::create("road_4.png");                roaddi->setFlipX(true);                roaddi->setAnchorPoint(ccp(0,1));                roaddi->setPosition( ccp(128 * i,0) );                bg1->addChild(roaddi,1);                break;            case 3:                road = CCSprite::create("road_5.png");                road->setAnchorPoint(ccp(0,0));                road->setPosition( ccp(128 * i,0) );                break;                       }           bg1->addChild(road,1);        }        if(bg2shu[i] != -1){           CCSprite *road1;           switch(bg2shu[i]){            case 0:                road1 = CCSprite::create("road_2.png");                road1->setAnchorPoint(ccp(0,0));                road1->setPosition( ccp(128 * i,0) );                roaddi = CCSprite::create("road_3.png");                                roaddi->setAnchorPoint(ccp(0,1));                roaddi->setPosition( ccp(128 * i,0) );                bg2->addChild(roaddi,1);                break;            case 1:                plant = CCSprite::create("back_3.png");                plant->setAnchorPoint(ccp(0.5,0));                plant->setPosition( ccp(128 * i + 128,117) );                bg2->addChild(plant,1);                road1 = CCSprite::create("road_1.png");                road1->setAnchorPoint(ccp(0,0));                road1->setPosition( ccp(26 + 128 * i,0) );                roaddi = CCSprite::create("road_4.png");                                roaddi->setAnchorPoint(ccp(0,1));                roaddi->setPosition( ccp(26 + 128 * i,0) );                bg2->addChild(roaddi,1);                break;            case 2:                road1 = CCSprite::create("road_1.png");                road1->setFlipX(true);                road1->setAnchorPoint(ccp(0,0));                road1->setPosition( ccp(128 * i,0) );                roaddi = CCSprite::create("road_4.png");                roaddi->setFlipX(true);                roaddi->setAnchorPoint(ccp(0,1));                roaddi->setPosition( ccp(128 * i,0) );                bg2->addChild(roaddi,1);                break;            case 3:                road1 = CCSprite::create("road_5.png");                road1->setAnchorPoint(ccp(0,0));                road1->setPosition( ccp(128 * i,0) );                break;                            }            bg2->addChild(road1,1);        }    }    state = 0;}
