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
