Unity + Admob 奖励广告：事件未触发

Question

我被 admob 奖励广告困住了，我不知道如何让活动发挥作用。问题是我的问答游戏会重新加载每个问题的场景，即使我阻止广告被破坏，事件也不会触发。广告完美展示。我尝试了多种方法，但我必须在某个地方犯错……有人有想法吗？

非常感谢！

这就是游戏如何处理场景的：

SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);

首先： 在您的活动中调用 RequestInterstial 方法似乎非常不明智/不合逻辑。因为这样做，您正在为您已经订阅的相同事件创建多个订阅！这可能会导致非常不受欢迎/不需要的行为以及导致Stackoverflow exceptions

我不清楚当事件触发时你为什么还要打电话给RequestInterstial。在我看来，您可能希望在显示第一个视频后加载一个新视频。重构您的方法，以便您不添加订阅事件。

将订阅事件和初始化代码移至您的 Start 或 Awake 方法。

另外，您请求的不是插页式视频，而是基于奖励的视频。我建议重命名以保持代码合乎逻辑。

Public static RewardedScriptRow Instance;

void Start()
{    
    Instance = this;
    DontDestroyOnLoad(this);
    RequestRewardBasedVideo();

    // Get singleton reward based video ad reference.
    this.rewardBasedVideo = RewardBasedVideoAd.Instance;

    rewardBasedVideo.OnAdFailedToLoad += HandleRewardBasedVideoClosed;
    rewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded;
}

private void RequestRewardBasedVideo()
    {
        #if UNITY_ANDROID
            string appId = "ca-app-pub-3940256099942544~3347511713";
        #elif UNITY_IPHONE
            string appId = "ca-app-pub-3940256099942544~1458002511";
        #else
            string appId = "unexpected_platform";
        #endif

        // Create an empty ad request.
        AdRequest request = new AdRequest.Builder().Build();
        // Load the rewarded video ad with the request.
        this.rewardBasedVideo.LoadAd(request, adUnitId);
    }

public void HandleRewardBasedVideoRewarded(object sender, Reward args)
{
    GetComponent<AudioSource>().PlayOneShot(GiftSound, 1.0F);
    RequestRewardBasedVideo();
}

除此之外，它应该可以工作。如果您仍然没有得到理想的结果，请尝试在调试时设置断点和/或在订阅的方法中使用Debug.Log() 来查看发生了什么。

编辑：另外，如果由于重新加载场景而发生，您可以尝试添加DontDestroyOnLoad(this); 以防止“AdObject”被破坏。我建议在您的第一个场景中创建此脚本并将其从所有其他场景中删除（以防止重复）。

然后您甚至可以应用singleton pattern，这样您就可以轻松地从其他类中访问该脚本。

例子：

StartCoroutine(RewardedScriptRow.Instance.LaunchAd());
