Google Mobile Ads Rewarded

AI Integration Agent Instructions for Unity Rewarded Ads

Required Imports

Use the following imports to implement a rewarded ad:

using System;
using UnityEngine;
using GoogleMobileAds.Api;
using GoogleMobileAds.Common;

Rewarded Ad Workflow

1. Load the ad:

   Use the static RewardedAd.Load() method passing the ad unit ID, an AdRequest object, and a completion callback (Action<RewardedAd, LoadAdError>):

   Copy

   // Test ad unit IDs. Replace with your own ad unit IDs.
   #if UNITY_ANDROID
       string adUnitId = "ca-app-pub-3940256099942544/5224354917";
   #elif UNITY_IPHONE
       string adUnitId = "ca-app-pub-3940256099942544/1712485313";
   #else
       string adUnitId = "unused";
   #endif

   Copy

   RewardedAd.Load(adUnitId, new AdRequest(),
       (RewardedAd ad, LoadAdError error) =>
       {
           if (error != null || ad == null)
           {
               // Handle the error.
               return;
           }
           rewardedAd = ad;
       });

   Always destroy any existing RewardedAd object before loading a new ad.

2. Register for ad event callbacks:

   Subscribing to ad events on the RewardedAd object is optional and depends on your application requirements:

   • OnAdPaid: Subscribe to log estimated ad revenue (AdValue) for impression-level ad monetization tracking.

   • OnAdImpressionRecorded: Subscribe to track ad impressions in internal telemetry or third-party analytics platforms.

   • OnAdClicked: Subscribe to record user clicks on the ad.

   • OnAdFullScreenContentOpened: Subscribe to pause game audio, timers, or gameplay loops when the rewarded ad covers the screen.

   • OnAdFullScreenContentClosed: Subscribe to resume game audio or gameplay loops when the ad is dismissed. Destroy the RewardedAd object (rewardedAd.Destroy()) and reload another ad (RewardedAd.Load()) so a fresh ad is ready for the next transition point.

   • OnAdFullScreenContentFailed: Subscribe to log display errors if the rewarded ad fails to show.

   Ensure background ad callbacks interacting with Unity objects (UnityEngine) are explicitly scheduled on the main thread using MobileAdsEventExecutor.ExecuteInUpdate(), because Unity APIs are not thread-safe and must be called from the main thread.

   Copy

   rewardedAd.OnAdFullScreenContentOpened += () =>
   {
       MobileAdsEventExecutor.ExecuteInUpdate(() =>
       {
           // Interact with UnityEngine objects on the main thread here.
       });
   };

3. Add a UI element to view the ad for a reward:

   MANDATORY: You MUST explicitly mention or demonstrate adding an interactive UI element (such as a Button) to trigger ShowRewardedAd(). Rewarded ads must never show automatically.

4. Show the ad:

   Check CanShowAd() on the RewardedAd object along with passing an Action<Reward> callback to the Show() method. Include a null check to avoid exceptions. Hook this method to an interactive UI Button:

   Copy

   // Call this method from a UI Button click event:
   public void ShowRewardedAd()
   {
       if (rewardedAd != null && rewardedAd.CanShowAd())
       {
           rewardedAd.Show((Reward reward) =>
           {
               // Reward the user.
               Debug.Log($"Rewarded! Amount: {reward.Amount}, Type: {reward.Type}");
           });
       }
   }

5. Verify the implementation: Ensure there are no compilation errors:

   • [ ] Verify the Unity Console has no C# script compile errors or missing GoogleMobileAds namespace references.
