# 8. 激励视频广告
# (1) Api说明
ATRewardedVideo：
| API | 参数 | 说明 |
|---|---|---|
| loadVideoAd | string placementid，Dictionary<string,string> extra | 加载广告 |
| hasAdReady | string placementid | 判断是否有广告缓存 |
| showAd | string placementid，Dictionary<string,string> extra | 显示广告 |
| cleanAd | string placementid | 清除广告 |
# (2) 加载激励视频
使用以下代码加载激励视频广告:
public void loadVideo()
{
if(callbackListener == null) {
callbackListener = new ATCallbackListener();
Debug.Log("Developer init video....unitid:" + mPlacementId_rewardvideo_all);
ATRewardedVideo.Instance.setListener(callbackListener);
}
Dictionary<string,string> jsonmap = new Dictionary<string,string>();
jsonmap.Add(ATConst.USERID_KEY, "test_user_id");
jsonmap.Add(ATConst.USER_EXTRA_DATA, "test_user_extra_data");
ATRewardedVideo.Instance.loadVideoAd(mPlacementId_rewardvideo_all,jsonmap);
}

注: 请参阅下文，了解如何获得有关激励视频广告事件的通知（加载成功/失败，展示，点击，视频开始/结束和激励）。
# (3) 展示激励视频
与展示原生广告相比，展示激励视频要简单得多，只要调用展示api并传递展示广告位ID作为参数：
public void showVideo()
{
Debug.Log ("Developer show video....");
ATRewardedVideo.Instance.showAd(mPlacementId_rewardvideo_all);
}

当用到场景功能时：
public void showVideo()
{
Debug.Log ("Developer show video....");
Dictionary<string, string> jsonmap = new Dictionary<string, string>();
jsonmap.Add(AnyThinkAds.Api.ATConst.SCENARIO, showingScenarioID);
ATRewardedVideo.Instance.showAd(mPlacementId_rewardvideo_all, jsonmap);
}

# (4) 实现激励视频的监听器
您可以实现ATRewardedVideo Listener接口的类，来获得有关激励视频广告事件的通知：
class ATCallbackListener : ATRewardedVideoListener {
public void onRewardedVideoAdLoaded(string unitId){
Debug.Log("Developer onRewardedVideoAdLoaded------");
}
public void onRewardedVideoAdLoadFail(string unitId, string code, string message){
Debug.Log("Developer onRewardedVideoAdLoadFail------:code" + code + "--message:" + message);
}
public void onRewardedVideoAdPlayStart(string unitId, ATCallbackInfo callbackInfo){
Debug.Log("Developer onRewardedVideoAdPlayStart------");
}
public void onRewardedVideoAdPlayEnd(string unitId, ATCallbackInfo callbackInfo){
Debug.Log("Developer onRewardedVideoAdPlayEnd------");
}
public void onRewardedVideoAdPlayFail(string unitId, string code, string message){
Debug.Log("Developer onRewardedVideoAdPlayFail------code:" + code + "---message:" + message);
}
public void onRewardedVideoAdPlayClosed(string unitId, bool isReward, ATCallbackInfo callbackInfo){
Debug.Log("Developer onRewardedVideoAdPlayClosed------isReward:" + isReward);
}
public void onRewardedVideoAdPlayClicked(string unitId, ATCallbackInfo callbackInfo){
Debug.Log("Developer onRewardVideoAdPlayClicked------");
}
public void onReward(string unitId, ATCallbackInfo callbackInfo){
Debug.Log("Developer onReward------");
}
}

创建此类的一个实例，并将其传递给加载api中的listener参数.
