统一旋转到3d的原始位置

强烈的文字,所以我在做一个游戏,其中有一个我可以控制的飞机。可以的,但是我想当我抬起钥匙时飞机重新对准它原来的旋转方向。我编的鳕鱼是这个,但是不起作用。平面仅重新对齐一帧,然后再次“未对齐”。这是代码-**

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

public class planemovement : MonoBehaviour
{
    public int fspeed = 10;
    float horizontal; float zrot;
    float vertical; float yrot;
    public float sense; public int lim = 0; 
    void Start()
    {


    }

    // Update is called once per frame
    void Update()
    {
        float rotz = Input.GetAxis("Vertical"); float roty = Input.GetAxis("Horizontal");
        horizontal = Input.GetAxis("Horizontal");
        vertical = Input.GetAxis("Vertical");
        transform.Translate(Vector3.forward * fspeed * Time.deltaTime);
        transform.Translate(Vector3.right * sense * Time.deltaTime * horizontal*20f);
        transform.Translate(Vector3.up * sense * Time.deltaTime * vertical);
        zrot -= rotz;
        yrot -= roty;
        zrot = Mathf.Clamp(zrot, -lim, lim);
        yrot = Mathf.Clamp(yrot, -lim, lim);
        transform.localRotation = Quaternion.Euler(zrot, 0f, yrot);


    }
