Question

因此，我制作了这个测试GUI，当敌人的聚光灯到达您时，该游戏显示了游戏画面。但是当它发生时，Unity崩溃并注意到了错误

StackOverflowException: The requested operation caused a stack overflow.

这是我崩溃的代码：

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


public class GameUI : MonoBehaviour {

    public GameObject gameLoseUI;
   // public GameObject playerDiedUI;
    //public GameObject noEnergyUI;
    bool gameIsOver;

    // Use this for initialization
    void Start () {
        Guard.OnGuardHasSpottedPlayer += ShowGameLoseUI;
    }

    // Update is called once per frame
    void Update () {
        /*if (gameIsOver)
        {if (Input.GetKeyDown(KeyCode.Space))
            {
                SceneManager.LoadScene(0);
            }
        }*/     
    }

    void ShowGameLoseUI()
    {
        OnGameOver(gameLoseUI);
    }

    void OnGameOver(GameObject gameoverUI)
    {
        gameLoseUI.SetActive(true);
        gameIsOver = true;
        Guard.OnGuardHasSpottedPlayer += ShowGameLoseUI;
    }
}

我认为该错误可能在void Update内，但即使带有此注释的代码段，Unity仍然会崩溃。我该如何解决这个问题？

如评论中所指出的，您在GameOver上无限订阅Guard.OnGuardHasSpottedPlayer，这会导致异常。

将+=更改为-=

void OnGameOver(GameObject gameoverUI)
    {
        gameLoseUI.SetActive(true);
        gameIsOver = true;
        Guard.OnGuardHasSpottedPlayer -= ShowGameLoseUI;
    }
