Unity 游戏在关闭基于奖励的视频广告时崩溃

Question

我使用的是 Google 的 AdMob 文档中的示例代码。广告加载正常，但当我关闭它时，游戏就崩溃了。我真的不知道是什么导致了这里的问题。该脚本附加到 AdManager 游戏对象，当用户按下 RewardPanel 上的按钮时调用函数 showRewardVideoAd()。

这里是logcat

}

Answer 1

没关系，我发现问题是由加载 rewardPanel 游戏对象上的大纹理引起的。通过用较小的纹理替换巨大的纹理解决了这个问题。

Answer 2

我也遇到了这个问题。我使用 Instantiate(m_obj)，用于 HandleUserEarnedReward 中的 null Object。所以不要忘记指向一个对象。
