这个是Cocostudio的JSON例子，请问一下如何将hostCity这个组件的坐标转换为GL坐标。
我通过这样的方法转换我觉得是不对的？
auto hostCity = (node->getChildByTag(10004)->getChildByTag(10006)->getComponent(“CCSprite”)->getOwner());
auto position = hostCity->getPosition();
auto posInGL = Director::getInstance()->convertToGL(position);
首先position的坐标是对于Parent节点的坐标，而Parent节点上面又嵌套了几层节点，我感到非常凌乱，请帮助。
