广告事件
要进一步自定义您的广告行为，您可以在广告生命周期内加入许多事件，如加载、打开、关闭等等。您可以通过为相应的EventHandler注册代理来监听这些事件。其中*重要的事件是OnAdRewarded，当用户因观看视频而应获得奖励时会调用该事件。您还可以实现其他广告事件，如下所示。
using GoogleMobileAds.Api;
...
public class GoogleMobileAdsDemoscript:MonoBehaviour
{
private RewardbasedVideoAd rewardbasedVideo;
...
public void Start()
{
//Get singleton reward based video ad reference.
this.rewardbasedVideo=RewardbasedVideoAd.Instance;
//Called when an ad request has successfully loaded.
rewardbasedVideo.OnAdLoaded+=HandleRewardbasedVideoLoaded;
//Called when an ad request failed to load.
rewardbasedVideo.OnAdFailedToLoad+=HandleRewardbasedVideoFailedToLoad;
//Called when an ad is shown.
rewardbasedVideo.OnAdOpening+=HandleRewardbasedVideoOpened;
//Called when the ad starts to play.
rewardbasedVideo.OnAdStarted+=HandleRewardbasedVideoStarted;
//Called when the user should be rewarded for watching a video.
rewardbasedVideo.OnAdRewarded+=HandleRewardbasedVideoRewarded;
//Called when the ad is closed.
rewardbasedVideo.OnAdClosed+=HandleRewardbasedVideoClosed;
//Called when the ad click caused the user to leave the application.
rewardbasedVideo.OnAdLeavingApplication+=HandleRewardbasedVideoLeftApplication;
this.RequestRewardbasedVideo();
}

AdRequest request=new AdRequest.Builder().Build();
//Load the rewarded video ad with the request.
