Unity查找物体下面某个子物体，添加脚本，添加父物体小功能（自己备份的）

	public class UnityHelper : MonoBehaviour {
        
        /// <summary>
        /// 查找子节点对象
        /// 内部使用“递归算法”
        /// </summary>
        /// <param name="goParent">父对象</param>
        /// <param name="chiildName">查找的子对象名称</param>
        /// <returns></returns>
	    public static Transform FindTheChildNode(GameObject goParent,string chiildName)
        {
            Transform searchTrans = null;                   //查找结果

            searchTrans=goParent.transform.Find(chiildName);
            if (searchTrans==null)
            {
                foreach (Transform trans in goParent.transform)
                {
                    searchTrans=FindTheChildNode(trans.gameObject, chiildName);
                    if (searchTrans!=null)
                    {
                        return searchTrans;

                    }
                }
