unity 3D: Admob 奖励广告事件回调仅触发一次

Question

我的游戏中有 Admob 奖励广告，一旦玩家死亡，我就有一个继续按钮，所以问题是当我点击继续时，广告显示并且玩家复活（回调触发）但是如果玩家再次死亡（同样的运行） ) 并单击以继续广告会显示，但不会触发回调，并且要触发回调，我必须重置场景。 广告一直显示，但每个场景只触发一次回调。

{
    public GameObject PlayerScript;
public static AdsManager AdsInstance;



string Rewarded_AD = "ca-app-pub-3940256099942544/5224354917"; // these all 3 ids are test ids, swap them later with real ids, delete this line when done
string Inter_AD = "ca-app-pub-3940256099942544/1033173712";

private RewardedAd rewardedAD;
// private RewardBasedVideoAd rewardedAD;
private InterstitialAd InterAd;

private void Awake()
{
    if (AdsInstance == null)
    {
        AdsInstance = this;
    }
    else if (AdsInstance != this)
    {

    }




}

private void Start() {
    MobileAds.Initialize(initStatus => {

        
        Debug.Log("Initialize done");
       


    });

    PlayerScript = GameObject.FindGameObjectWithTag("players");



    this.RequestRewardedAd();
    this.RequestInterAd();


    this.rewardedAD.OnAdClosed += HandleRewardedAdCloseed;
    this.rewardedAD.OnUserEarnedReward += HandleUserEarnedRewards;

   
}
private void Update()
{
    PlayerScript = GameObject.FindGameObjectWithTag("players");

   
}


public void RequestRewardedAd()
{
    //  this.rewardedAD =  RewardBasedVideoAd.Instance;   //RewardBasedVideoAds(Deprecated ones)

    this.rewardedAD = new RewardedAd(Rewarded_AD);

    AdRequest request = new AdRequest.Builder().Build();
  //  this.rewardedAD.LoadAd(request, Rewarded_AD);     //RewardBasedVideoAds(Deprecated ones)
    this.rewardedAD.LoadAd(request);
}


public void ShowRewardBasedVideoAds()
{
    if (rewardedAD.IsLoaded())
    {
        rewardedAD.Show();
        
    }
}


public void RequestInterAd()
{
    this.InterAd = new InterstitialAd(Inter_AD);


    AdRequest request = new AdRequest.Builder().Build();

    this.InterAd.LoadAd(request);

}
public void ShowInterstitialAd()
{
    if (InterAd.IsLoaded())
    {

        InterAd.Show();
        ScoreManagerScript.ScoreInstance.AddCoinsOnWatchingAd();




        RequestInterAd();
    }

}


public void HandleRewardedAdCloseed(object sender, EventArgs args)
{
   
    MonoBehaviour.print("HandleRewardedAdClosed event received");
    this.RequestRewardedAd();
    PlayerScript.GetComponent<Player>().rb.isKinematic = true;
    PlayerScript.GetComponent<Player>().StartEnemySpikeTimer();
    // ScoreManagerScript.ScoreInstance.ReAddTheCoinsIfAdIsClosed();

}


public void HandleUserEarnedRewards(object sender, Reward args)
{

  
    MonoBehaviour.print("HandleRewardedAd event received ");

    PlayerScript.GetComponent<Player>().ReSpawnPlayer();

    ScoreManagerScript.ScoreInstance.ReduceCoinsOnContinue();

    this.RequestRewardedAd();
    
}

此外，我尝试将广告订阅交换为 RequestRewardedAd() 方法，所以它也不起作用，实际上当我这样做时，每个场景只显示一个广告并且只有一个回调。

请帮忙谢谢

我想我发现了可能有问题的地方，请给它一个测试并告诉我它是否有效，我现在无法测试它。

尝试添加以下 function：

void InitializeRewardedAd()
{
    //Creating a new instance of rewarded ads
    this.rewardedAD = new RewardedAd(Rewarded_AD);

    //loading the ads
    AdRequest request = new AdRequest.Builder().Build();

    this.rewardedAD.LoadAd(request);

    //subscribing the events to that new instance
    this.rewardedAD.OnAdClosed += HandleRewardedAdCloseed;
    this.rewardedAD.OnUserEarnedReward += HandleUserEarnedRewards;
}

并在您关闭奖励广告HandleRewardedAdCloseed时调用InitializeRewardedAds() （您只需要在关闭它时调用它一次，您当前在关闭它和触发奖励时都调用它）

我认为问题可能是事件没有被订阅到广告的新实例，只是在开始时，所以只有当你重新启动场景时，它才会再次被订阅。

PS：还有一件事，你真的需要每帧搜索“PlayerScript”吗？ 它会影响你的表现。 也许在Start()做一次会更好。
