游戏对象已被破坏，但您仍在尝试访问它

Question

我正在尝试制作一个统一的广告，以便当玩家输了时，他可以观看广告继续。但是，当我更改场景并尝试再次观看广告时，它显示 HeartMenu.SetActive(false) 的游戏对象已被销毁，但您仍在尝试访问它，但我的脚本只是将心形菜单设置为 SetActive(false) ）。我该如何解决这个问题？

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Advertisements;

public class RewardedAdsButton : MonoBehaviour, 
IUnityAdsLoadListener, IUnityAdsShowListener
{
[SerializeField] Button _showAdButton;
[SerializeField] string _androidAdUnitId = 
"Rewarded_Android";
[SerializeField] string _iOSAdUnitId = "Rewarded_iOS";
string _adUnitId = null; // This will remain null for 
unsupported platforms

public GameObject Restart;

public GameObject HeartMenu;

void Awake()
{
  
#if UNITY_IOS
    _adUnitId = _iOSAdUnitId;
#elif UNITY_ANDROID
    _adUnitId = _androidAdUnitId;
#endif

  

}

public void Update()
{


 
}

// Load content to the Ad Unit:
public void LoadAd()
{
    // IMPORTANT! Only load content AFTER initialization (in this example, initialization is handled in a different script).
    Debug.Log("Loading Ad: " + _adUnitId);
    Advertisement.Load(_adUnitId, this);
}

// If the ad successfully loads, add a listener to the button and enable it:
public void OnUnityAdsAdLoaded(string adUnitId)
{
    Debug.Log("Ad Loaded: " + adUnitId);

    if (adUnitId.Equals(_adUnitId))
    {
        // Configure the button to call the ShowAd() method when clicked:
        _showAdButton.onClick.AddListener(ShowAd);
        // Enable the button for users to click:
        _showAdButton.interactable = true;
    }
}

// Implement a method to execute when the user clicks the button:
public void ShowAd()
{
    // Disable the button:
    _showAdButton.interactable = false;
    // Then show the ad:
    Advertisement.Show(_adUnitId, this);
}

// Implement the Show Listener's OnUnityAdsShowComplete callback method to determine if the user gets a reward:
public void OnUnityAdsShowComplete(string adUnitId, UnityAdsShowCompletionState showCompletionState)
{
    if (adUnitId.Equals(_adUnitId) && showCompletionState.Equals(UnityAdsShowCompletionState.COMPLETED))
    {
        Debug.Log("Unity Ads Rewarded Ad Completed");
        // Grant a reward.
        HeartMenu.SetActive(false);
        OnDestroy();
        Time.timeScale = 1f;
        // Load another ad:
        Advertisement.Load(_adUnitId, this);
    }
}
