Unity只能以特定角度和位置传送另一个游戏对象

我正在尝试创建门户，但是我不明白为什么要使用代码：

playerControl.transform.position = new Vector3(destination.position.x, destination.position.y, destination.position.z);

仅适用于某些位置和角度。

这是代码的设置

    public class Teleport : Interactable
{
    public Transform destination;
    private GameObject playerControl;
    private PortalAnimationController portalController;

    // Start is called before the first frame update
    void Start()
    {//get the player information
        playerControl = PlayerManager.instance.player;
        portalController = PortalAnimationController.instance;
    }


    public override void interact()
    {
        //base.interact();
        //run the teleport method

        StartCoroutine("teleport");

        //Debug.Log(playerControl.GetInstanceID());

    }


    /*
     1. trigger the panel
     2. stop the time
     3. teleport the player
     */
    private IEnumerator teleport()
    {
        Time.timeScale = 0f;//stop the time
        portalController.fadeOut();
        //wait for seconds realtime can avoid stopping when timescale is 0
        yield return new WaitForSecondsRealtime(portalController.duration);//wait for the transition
        Debug.Log("wait finish");
        //after the the wait
        Debug.Log(playerControl.transform.position + "before");
        playerControl.transform.position = new Vector3(destination.position.x, destination.position.y, destination.position.z);
        if(playerControl.transform.position!= destination.position)
        {
            Debug.Log(playerControl.transform.position);
        }
        else
        {
            Debug.Log(playerControl.transform.position+"pass");
        }
        portalController.fadeOut();
        Time.timeScale = 1f;
    }
}

可交互类仅包含一个“公共虚拟void interact（）”方法，以使传送能够覆盖它。触发方法是通过以下代码：

void Update()
    {
        RaycastHit hit;
        if (Input.GetButtonDown("Interact"))
        {
            if (Physics.Raycast(cam.transform.position, cam.transform.forward, out hit, interactableRange))
            {
                Interactable interactable = hit.collider.GetComponent<Interactable>();
                //if the player is looking at the interactable
                //Debug.Log("Interact with " + hit.transform.name);
                if (interactable != null)
                {
                    //highlight the object
                    interactable.interact();
                    //if player press the interact key, then pick it up
                    Debug.Log("Interact with " + hit.transform.name);


                }
            }
        }
    }

当按下e键时，它将发出光线，然后击中对撞机框以检索可交互组件并立即调用interact（）。

我已经对其进行了数百次测试，只有3个结果。1.玩家实际上被传送了。（成功）2.玩家以1帧的速度闪烁到目的地，然后又回到了原来的位置。（失败）3.玩家根本没有移动。（失败）
