unity-game-engine - 如何在 Unity 应用程序中创建多个奖励视频？

Question

最近几天，我尝试在我的 Unity 应用程序中实现奖励视频 (admob)。我希望人们可以观看多种奖励视频，并获得不同类型的奖励。我觉得我很接近(也许根本不是)，因为我让它几乎正常工作。第一次点击测试广告时，它会显示该广告，我会收到奖励以及我收到奖励的消息。如果我随后加载/观看第二个广告，它会起作用，但奖励并不应有。我得到了两种奖励。所以，我首先观看一个 100 个硬币的广告，我得到了 100 个硬币，而且效果很好。然后，我观看了 500 个硬币的广告，但我得到了 600 个硬币，并且我收到了 100 个和 500 个硬币的消息，尽管我只“赚”了 500 个硬币。看起来 HandleRewardBasedVideoRewardedAdMob 的某个地方都有错误，但我已经尝试了我能想到的一切，但我没有在互联网上找到类似的东西。我用小号奖励100个硬币，用大号奖励500个硬币。 我希望有人能帮助我，因为这让我发疯。感谢您的宝贵时间!

RewardBasedVideoAd 是一个单一对象(与 BannerView 和 InterstitialAd 不同)。在您的InitializeAds方法中，您将相同的对象分配给RequestRewardedVideosmall和rewardBasedAdMobVideobig。您一次不能请求多个 RewardBasedVideoAd。

Because RewardedBasedVideoAd is a singleton, requests to load an ad should be made using a shared instance.
