unity 获取transform的所有子节点

如下，路径存储在dropDownList内

 

        ValueDropdownList<string> dropDownList = new ValueDropdownList<string>();

        public ValueDropdownList<string> GetActorPaths()
        {
            if (actor == null) return null;
            dropDownList.Clear();
            var actorTrans = actor.transform;
            dropDownList.Add("root");
            GetAllChild(actorTrans, "root");
            return dropDownList;
        }

        public void GetAllChild(Transform rootTrans, string rootPath = "")
        {
            if (rootTrans.childCount == 0) return;
            var count = rootTrans.childCount;

            for (int i = 0; i < count; i++)
            {
                var nextPath = rootPath;
                var trans = rootTrans.GetChild(i);
                nextPath = rootPath + "/" + trans.name;
                if (trans.GetComponent<BaseActor>())
                {
                    dropDownList.Add(nextPath);
                }

                GetAllChild(trans, nextPath);
            }
        }
