如何檢查廣​​告是否已在Unity中完成

Question

我使用的是來自admob的激勵視頻廣告。廣告在玩家死亡時被調用，並詢問他們是否想要觀看要復活的廣告。我試圖檢查廣告是否完成，以便我可以獎勵玩家。

void Update() 
{ 
    if(isCalled == true){ 
     string adUnitId = "ca-app-pub-5920324855307233/4458481507"; 
     RewardBasedVideoAd rewardBasedVideo = RewardBasedVideoAd.Instance; 
     AdRequest request = new AdRequest.Builder().Build(); 
     rewardBasedVideo.LoadAd(request, adUnitId); 
     showAd(rewardBasedVideo); 
    } 
} 

public void showAd(RewardBasedVideoAd rewardBasedVideo) 
{ 
    if (rewardBasedVideo.IsLoaded()) 
    { 
     //Subscribe to Ad event 
     rewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded; 
     rewardBasedVideo.Show(); 
    } 
} 

public void HandleRewardBasedVideoRewarded(object sender, Reward args) 
{ 
    string type = args.Type; 
    double amount = args.Amount; 
    //Reawrd User here 
    print("User rewarded with: " + amount.ToString() + " " + type); 

    isCalled = false; 

    managerScript.revival(); 
    managerScript.Loading.SetActive(false); 
} 

第一次通告了對場景中的方法復興被調用，加載屏幕觀看被關閉，一切正常，之後，當廣告再次它不工作的注視下，「HandleRewardBasedVideoRewarded」方法沒有被調用，一個新的廣告只是彈出來觀看一遍又一遍。我如何解決這個問題，因爲當廣告第二次完成時，遊戲不會調用「HandleRewardBasedVideoRewarded」方法。所以方法的復甦被調用，並且加載屏幕像第一次打開遊戲時一樣關閉。 注意：即使場景重新啓動（而不是整個遊戲），問題仍然會發生。

更新： 我已編輯腳本到您的解決方案，但問題仍然存在。 Whay不是在工作嗎？ 以下是完整的腳本：

using UnityEngine; 
using UnityEngine.UI; 
using System.Collections; 
using GoogleMobileAds; 
using GoogleMobileAds.Api; 
using UnityEngine.Advertisements; 

public class GameAdvertising : MonoBehaviour { 

    public bool isCalled; 
    public GameObject Manager; 
    GameManager managerScript; 

    string adUnitId = "ca-app-pub-5920324855307233/4458481507"; 
    RewardBasedVideoAd rewardBasedVideo = null; 

    void Start() { 
     managerScript = gameObject.GetComponent<GameManager>(); 

     isCalled = false; 

     //Subscribe to Ad event once 
     rewardBasedVideo = RewardBasedVideoAd.Instance; 
     //Subscribe to Ad event once 
     rewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded; 

    } 

    public void adButton() 
    { 
     isCalled = true; 
    } 

    void Update() 
    { 
     if(isCalled == true){ 
      AdRequest request = new AdRequest.Builder().Build(); 
      rewardBasedVideo.LoadAd(request, adUnitId); 
      showAd(); 
     } 
    } 

    public void showAd() 
    { 
     if (rewardBasedVideo.IsLoaded()) 
     { 
      rewardBasedVideo.Show(); 
     } 
    } 

    public void HandleRewardBasedVideoRewarded(object sender, Reward args) 
    { 
     string type = args.Type; 
     double amount = args.Amount; 
     //Reawrd User here 
     print("User rewarded with: " + amount.ToString() + " " + type); 

     isCalled = false; 

     managerScript.revival(); 
     managerScript.Loading.SetActive(false); 
    } 
}

很可能是因爲您多次註冊到的事件，當你調用不止一次rewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded;更多。你應該從那裏刪除它，並把它放在啓動功能。

string adUnitId = "ca-app-pub-5920324855307233/4458481507"; 
RewardBasedVideoAd rewardBasedVideo = null; 

void Start() 
{ 
    //Subscribe to Ad event once 
    rewardBasedVideo = RewardBasedVideoAd.Instance; 
    //Subscribe to Ad event once 
    rewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded; 
} 

public void adButton() 
{ 
    AdRequest request = new AdRequest.Builder().Build(); 
    rewardBasedVideo.LoadAd(request, adUnitId); 
    showAd(); 
} 

void Update() 
{ 

} 

public void showAd() 
{ 
    print("IN showAd()"); 
    if (rewardBasedVideo.IsLoaded()) 
    { 
     print("IN showAd() AND IsLoaded()"); 
     rewardBasedVideo.Show(); 
    }else{ 
     print("IN showAd() NOT IsLoaded()"); 
    } 
} 

public void HandleRewardBasedVideoRewarded(object sender, Reward args) 
{ 
    print("IN HandleRewardBasedVideoRewarded()"); 
    IsLoaded() 
    string type = args.Type; 
    double amount = args.Amount; 
    //Reawrd User here 
    print("User rewarded with: " + amount.ToString() + " " + type); 


    managerScript.revival(); 
    managerScript.Loading.SetActive(false); 
} 

public void OnDestroy() 
{ 
    //Un-Subscribe to Ad event once 
    rewardBasedVideo.OnAdRewarded -= HandleRewardBasedVideoRewarded; 
}
