对观看广告的用户进行奖励可以增加用户参与度，从而带来更高收入。例如，游戏可以用游戏币、消耗品、额外生命数量或经验倍增法宝来奖励用户。如需了解如何有效设计奖励广告的更多信息，请参阅变现策略指南。 要奖励用户看完视频广告，请使用
IUnityAdsShowListener.onUnityAdsShowCompleteUnityAdsShowCompletionState奖励视频广告示例
注意
Unity Ads 需要访问当前正在运行的 Activity，所以下面的示例使用 。
由于这可能不适合所有实现，因此可能需要进行一些定制（具体取决于集成情况）。

奖励视频广告按钮
使用按钮让玩家选择观看广告是奖励视频广告的常见实现方式。可使用以下示例代码来创建奖励广告按钮。只要事先加载了广告，就会在按下广告按钮时展示广告。有关配置按钮的信息，请参阅有关按钮的 Android 开发者文档。 实现按钮后，请添加一个包含以下代码的脚本，其中showAdButton注意
