写的代码小键盘上下左右正常，WASD出问题

Question

一开始W可以用S用不了，点了AD以后WS都用不了，只能左右动

public float horizontal = 0f;
public float vertical = 0f;
public float speed = 2f;
public Vector3 direction = new Vector3(0, 1, 0);
public bool isVerticalAvailable = false;
private Vector3 playerRotation = Vector3.zero;
// Start is called before the first frame update
void Start()
{
    
}

// Update is called once per frame
void Update()
{
    //1 通过键盘按钮按下以及松开，来获取水平/垂直方向的可用性
    if (Input.GetKeyDown(KeyCode.DownArrow) || Input.GetKeyDown(KeyCode.UpArrow))
    {
        isVerticalAvailable = true ;
    }
    if (Input.GetKeyDown(KeyCode.LeftArrow) || Input.GetKeyDown(KeyCode.RightArrow))
    {
        isVerticalAvailable = false ;
    }
    if (Input.GetKeyUp(KeyCode.DownArrow) || Input.GetKeyUp(KeyCode.UpArrow))
    {
        isVerticalAvailable = false ;
    }
    if (Input.GetKeyUp(KeyCode.LeftArrow) || Input.GetKeyUp(KeyCode.RightArrow))
    {
        isVerticalAvailable = true ;
    }
    //通过Input控制器判断方向
    horizontal = Input.GetAxisRaw("Horizontal");
    vertical = Input.GetAxisRaw("Vertical");
    //垂直方向
    if (isVerticalAvailable) 
    {
        if (vertical > 0) //上
        {
            playerRotation = Vector3.zero;
        }
        if (vertical < 0) //下
        {
            playerRotation = new Vector3(0,0,180);
        }
    }
    //水平方向
    if (!isVerticalAvailable)
    {
        if (horizontal > 0) //右
        {
            playerRotation = new Vector3(0, 0, -90);
        }
        if (horizontal < 0) //左
        {
            playerRotation = new Vector3(0, 0, 90);
        }
    }
    //重置游戏方向
    this.transform.rotation = Quaternion.Euler(playerRotation);
    if (horizontal!=0 || vertical!=0) 
    {
        this.transform.Translate(direction * speed * Time.deltaTime);
    }
}

你这写的好乱啊

        if (Input.GetKey(KeyCode.W) || Input.GetKey(KeyCode.UpArrow)) //前移
        {
            transform.Translate(Vector3.forward * speed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.S) || Input.GetKey(KeyCode.DownArrow)) //后移
        {
            transform.Translate(Vector3.back * speed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.LeftArrow)) //左移
        {
            transform.Translate(Vector3.left * speed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow)) //右移
        {
            transform.Translate(Vector3.right * speed * Time.deltaTime);
        }

或者

        horizontal = Input.GetAxisRaw("Horizontal");
        vertical = Input.GetAxisRaw("Vertical");

        if(horizontal!=0 || vertical!=0)
        {
            transform.Translate(new Vector3(horizontal,0,vertical) * speed * Time.deltaTime);
        }
