Unity广告，视频始终无法显示

Question

我有这个代码，每次打印出该视频后，我都会用按钮控制台执行它，但它失败了。也许我只是不知道如何在Unity中启用广告。我启用了测试模式。这是我的代码。 ：

FIXED 我只需要替换此行

  

public string placementId =“rewardedVideo”;

用这个：

  

Advertisement.Show（placementId，options）;

私人字符串gameId =“1523603”;

void Start(){ 
        Advertisement.Initialize (gameId);
}
public void ShowAd (){
    var options = new ShowOptions();
    options.resultCallback = HandleShowResult;
    Debug.Log (Advertisement.IsReady ("rewardedVideo"));
    Advertisement.Show(gameId, options);
}

void HandleShowResult (ShowResult result){
    if(result == ShowResult.Finished) {
        Debug.Log("Video completed - Offer a reward to the player");
        OnemoreTry ();

    }else if(result == ShowResult.Skipped) {
        Debug.LogWarning("Video was skipped - Do NOT reward the player");

    }else if(result == ShowResult.Failed) {
        Debug.LogError("Video failed to show");
    }
}
