有没有办法检查游戏对象是否已被销毁？

Question

我正在创建一个游戏，我想在玩家死亡时显示一个面板

我尝试了不同的方法，但似乎没有一个能做我想做的

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

public class DeadOrAlive : MonoBehaviour
{

    public GameObject Player;
    public GameObject deadPanel;

    void Update()
    {
        if (!GameObject.FindWithTag("Player"))
        {
            deadPanel.SetActive(true);
        }
    }


}

要检查对象是否已被销毁，您应该OnDestroy像这样使用 MonoBehavior ：

// Attach this script to the player object
public class DeadOrAlive : MonoBehaviour
{
    public GameObject deadPanel;

    void OnDestroy()
    {
        deadPanel.SetActive(true);
    }
}

您也可以不销毁玩家对象，而是将其设置为活动/非活动状态，但是要以这种方式检查玩家是死是活，您将需要一个单独的对象来检查活动状态：

//Attach this to a object which isn't a child of the player, maybe a dummy object called "PlayerMonitor" which is always active
public class DeadOrAlive : MonoBehaviour
{
    public GameObject deadPanel;

    void Update()
    {
        if (!GameObject.FindWithTag("Player"))
        {
            deadPanel.SetActive(true);
        }
    }
}

有一段时间没有使用 unity 了，忘记了它会变得多么奇怪。
