獎勵廣告

使用者可選擇與獎勵廣告互動 獲得應用程式內獎勵本指南說明如何在以下平台中整合獎勵廣告: AdMob 整合到 Unity 應用程式中。

本指南說明如何將獎勵廣告整合至 Unity 應用程式。

必要條件

一律使用測試廣告進行測試

以下程式碼範例包含廣告單元 ID,供您請求 測試廣告系統已特別將其設定為針對每項請求傳回測試廣告,而非正式廣告,因此可安全使用。

不過,在 Ad Manager 網頁介面,並建立自己的廣告單元 用於應用程式的 ID,請明確將裝置設為測試裝置 裝置

/21775744923/example/rewarded

初始化 Mobile Ads SDK

載入廣告前,請呼叫應用程式,以便呼叫 MobileAds.Initialize()。這項操作只需進行一次,最好在應用程式啟動時。

using GoogleMobileAds;
using GoogleMobileAds.Api;

public class GoogleMobileAdsDemoScript : MonoBehaviour
{
    public void Start()
    {
        // Initialize the Google Mobile Ads SDK.
        MobileAds.Initialize((InitializationStatus initStatus) =>
        {
            // This callback is called once the MobileAds SDK is initialized.
        });
    }
}

如果您使用中介服務,請等到回呼發生後,再於 以確保所有中介服務轉接程式的初始化完成。

導入作業

整合獎勵廣告的主要步驟如下:

  1. 載入獎勵廣告
  2. [選用] 驗證伺服器端驗證 (SSV) 回呼
  3. 顯示獎勵廣告與獎勵回呼
  4. 監聽獎勵廣告事件
  5. 清除獎勵廣告
  6. 預先載入下一個獎勵廣告

載入獎勵廣告

您可以使用 RewardedAd 類別上的靜態 Load() 方法載入獎勵廣告。所載入的 RewardedAd 物件會做為 參數。以下範例說明如何載入 RewardedAd


  // This ad unit is configured to always serve test ads.
  private string _adUnitId = "/21775744923/example/rewarded";

  private RewardedAd _rewardedAd;

  /// <summary>
  /// Loads the rewarded ad.
  /// </summary>
  public void LoadRewardedAd()
  {
      // Clean up the old ad before loading a new one.
      if (_rewardedAd != null)
      {
            _rewardedAd.Destroy();
            _rewardedAd = null;
      }

      Debug.Log("Loading the rewarded ad.");

      // create our request used to load the ad.
      var adRequest = new AdManagerAdRequest();

      // send the request to load the ad.
      RewardedAd.Load(_adUnitId, adRequest,
          (RewardedAd ad, LoadAdError error) =>
          {
              // if error is not null, the load request failed.
              if (error != null || ad == null)
              {
                  Debug.LogError("Rewarded ad failed to load an ad " +
                                 "with error : " + error);
                  return;
              }

              Debug.Log("Rewarded ad loaded with response : "
                        + ad.GetResponseInfo());

              _rewardedAd = ad;
          });
  }

[選用] 驗證伺服器端驗證 (SSV) 回呼

如果應用程式在伺服器端驗證回呼中需要額外資料,則應使用獎勵廣告的自訂資料功能。在獎勵廣告物件上設定的任何字串值都會傳遞至 custom_data SSV 回呼的查詢參數。如果未設定自訂資料值, custom_data 查詢參數值不會顯示在 SSV 回呼中。

以下程式碼範例示範如何在 已載入獎勵廣告。

// send the request to load the ad.
RewardedAd.Load(_adUnitId, adRequest, (RewardedAd ad, LoadAdError error) =>
{
    // If the operation failed, an error is returned.
    if (error != null || ad == null)
    {
        Debug.LogError("Rewarded ad failed to load an ad with error : " + error);
        return;
    }

    // If the operation completed successfully, no error is returned.
    Debug.Log("Rewarded ad loaded with response : " + ad.GetResponseInfo());

    // Create and pass the SSV options to the rewarded ad.
    var options = new ServerSideVerificationOptions
                          .Builder()
                          .SetCustomData("SAMPLE_CUSTOM_DATA_STRING")
                          .Build()
    ad.SetServerSideVerificationOptions(options);

});

如要設定自訂獎勵字串,請務必在顯示廣告前設定。

透過獎勵回呼顯示獎勵廣告

顯示廣告時,您必須提供回呼來處理 使用者。廣告每次載入時只能顯示一次。使用 CanShowAd() 方法 確認廣告已經準備好可以放送。

以下程式碼是顯示獎勵廣告的最佳方法。

public void ShowRewardedAd()
{
    const string rewardMsg =
        "Rewarded ad rewarded the user. Type: {0}, amount: {1}.";

    if (rewardedAd != null && rewardedAd.CanShowAd())
    {
        rewardedAd.Show((Reward reward) =>
        {
            // TODO: Reward the user.
            Debug.Log(String.Format(rewardMsg, reward.Type, reward.Amount));
        });
    }
}

監聽獎勵廣告事件

如要進一步自訂廣告行為,您可以連結至 事件中的事件 (例如開啟和關閉等等)。如要監聽這些事件,請註冊委派函,如以下所示。

private void RegisterEventHandlers(RewardedAd ad)
{
    // Raised when the ad is estimated to have earned money.
    ad.OnAdPaid += (AdValue adValue) =>
    {
        Debug.Log(String.Format("Rewarded ad paid {0} {1}.",
            adValue.Value,
            adValue.CurrencyCode));
    };
    // Raised when an impression is recorded for an ad.
    ad.OnAdImpressionRecorded += () =>
    {
        Debug.Log("Rewarded ad recorded an impression.");
    };
    // Raised when a click is recorded for an ad.
    ad.OnAdClicked += () =>
    {
        Debug.Log("Rewarded ad was clicked.");
    };
    // Raised when an ad opened full screen content.
    ad.OnAdFullScreenContentOpened += () =>
    {
        Debug.Log("Rewarded ad full screen content opened.");
    };
    // Raised when the ad closed full screen content.
    ad.OnAdFullScreenContentClosed += () =>
    {
        Debug.Log("Rewarded ad full screen content closed.");
    };
    // Raised when the ad failed to open full screen content.
    ad.OnAdFullScreenContentFailed += (AdError error) =>
    {
        Debug.LogError("Rewarded ad failed to open full screen content " +
                       "with error : " + error);
    };
}

清理獎勵廣告

完成 RewardedAd 後,請務必呼叫 Destroy() 方法,再放置您的參照:

_rewardedAd.Destroy();

這會通知外掛程式,說明該物件已不再使用,以及該物件的記憶體 可收回這些物件。無法呼叫此方法會導致記憶體流失。

預先載入下一個獎勵廣告

RewardedAd 是一次性的物件。也就是說,獎勵廣告顯示後 以再次使用物件如要要求其他獎勵廣告,您必須建立新的 RewardedAd 物件。

如要為下一個曝光商機準備獎勵廣告,請預先載入 OnAdFullScreenContentClosed 或 會引發 OnAdFullScreenContentFailed 個廣告事件。

private void RegisterReloadHandler(RewardedAd ad)
{
    // Raised when the ad closed full screen content.
    ad.OnAdFullScreenContentClosed += () =>
    {
        Debug.Log("Rewarded Ad full screen content closed.");

        // Reload the ad so that we can show another as soon as possible.
        LoadRewardedAd();
    };
    // Raised when the ad failed to open full screen content.
    ad.OnAdFullScreenContentFailed += (AdError error) =>
    {
        Debug.LogError("Rewarded ad failed to open full screen content " +
                       "with error : " + error);

        // Reload the ad so that we can show another as soon as possible.
        LoadRewardedAd();
    };
}
