unity传送门

using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneTransition : MonoBehaviour
{
    [SerializeField] private string sceneName;
    [SerializeField] public string password;

    private void OnTriggerEnter2D(Collider2D other)
    {
        if(other.CompareTag("Player"))
        {
            PlayerMovement.Instance.scenePassword = password;
            SceneManager.LoadSceneAsync(sceneName);
        }
    }
}
创建一个精灵，添加碰撞触发，挂载此脚本，上面写上要传送到的场景名字，下面是唯一的密码，这个是入口，拖入图片，并放在你想当作进门的地方，

```csharp
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Entrance : MonoBehaviour
{
    public string entrancePassword;

    private void Start()
    {
        if(PlayerMovement.Instance.scenePassword == entrancePassword)
        {
            PlayerMovement.Instance.transform.position = transform.position;
        }
        else
        {
            Debug.LogError("Wrong PW. Please Check your Scene name and Entrance password");
        }
    }
}

创建一个空物体挂在上面的精灵下，并挂上上面的脚本，写上角色所在地图名字，这是出口，并放在你想出现的地方
