bool HelloWorld::init(){ if ( !Layer::init() ) { return false; } Size visibleSize = Director::getInstance()->getVisibleSize(); Vec2 origin = Director::getInstance()->getVisibleOrigin();
CCTMXTiledMap* map = CCTMXTiledMap::create("map.tmx"); this->addChild(map, 0);
CCTMXLayer *layerGround = map->layerNamed("layer1"); CCTMXLayer *layerObstacle = map->layerNamed("layer2"); CCPoint pp = ccp(2, 2);
layerGround->tileGIDAt(CCPoint(0, 0));}
这样的代码出错，为什么？
