Unity Rewarded Interstitial with Google Mobile Ads v6.0.2 - 教程中的代码不起作用

Question

我正在尝试在 Unity 中向我的游戏添加广告，但不幸的是，使用官方 google 指南 (developers.google.com/admob/unity/rewarded-interstitial) 中的示例，我收到错误消息。谁能帮我解决这个问题？

public void Start()
{
    string adUnitId;
    #if UNITY_ANDROID
    adUnitId = trueRewardedAdId;
    #elif UNITY_EDITOR
    adUnitId = fakeRewardedAdId;
    #else
    adUnitId = "unexpected_platform";
    #endif

    // Create an empty ad request.
    AdRequest request = new AdRequest.Builder().Build();
    // Load the rewarded ad with the request.
    // Create an interstitial.
    RewardedInterstitialAd.LoadAd(adUnitId, request, AdLoadCallback);
}

private void AdLoadCallback(RewardedInterstitialAd ad, string error)
{
    if (error == null)
    {
        rewardedInterstitialAd = ad;

        rewardedInterstitialAd.OnAdFailedToPresentFullScreenContent += HandleAdFailedToPresent;
        rewardedInterstitialAd.OnAdDidPresentFullScreenContent += HandleAdDidPresent;
        rewardedInterstitialAd.OnAdDidDismissFullScreenContent += HandleAdDidDismiss;
        rewardedInterstitialAd.OnPaidEvent += HandlePaidEvent;
    }
}

更新 LoadAd() 以使用操作作为参数，并在回调中将参数“错误”类型从字符串更改为 AdFailedToLoadEventArgs。

public void Start()
{
   ...
    RewardedInterstitialAd.LoadAd(adUnitId, request, (req,err) => 
adLoadCallback(req, err));
}

private void AdLoadCallback(RewardedInterstitialAd ad, AdFailedToLoadEventArgs error)
{
  ...
}
