单位博弈中对撞机及其旋转问题

问题是我要创造一个可打开的门。当玩家进入与门相连的对撞机时,该门应打开。但问题是,当门开始打开和旋转时,碰撞机也开始旋转,这给我带来了很多使用这种想法的问题。我试图用它的碰撞器创建EmptyObject,但是我不能用脚本和OnTiggerCenter函数本身连接这个碰撞器。也许我不明白,谁知道,我只是个乞丐。怎么会帮忙,请写个答案。 如果有人需要我的代码:

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;

    public class openDoor : MonoBehaviour {

        public Vector3 Rotation_;
        private int i;
        public float speed;

        bool opentheDoor;
        bool closetheDoor;

        // Use this for initialization
        void Start () {
            opentheDoor = false;
            closetheDoor = false;

        }

        // Update is called once per frame
        void Update () {
            if (opentheDoor == true) {
                this.transform.Rotate (Rotation_ * Time.deltaTime * speed);
                i += 1;
                    if (i == 70) {
                        opentheDoor = false;
                        i = 0;
                    }
            }

            if (closetheDoor == true) {
                this.transform.Rotate (-Rotation_ * Time.deltaTime * speed);
                i += 1;
                if (i == 70) {
                    closetheDoor = false;
                    i = 0;
                }
            }

        }

        void OnTriggerEnter (Collider other) {  
            if (other.gameObject.tag == "Player") { {
               opentheDoor = true;
            }
            }
        }

        void OnTriggerExit (Collider other) {
            if (other.gameObject.tag == "Player") {
                closetheDoor = true;
            }
        }
    }
