How to Add Rewarded (Android) Ads in Unity

 

Monetizing your Unity game through ads is a popular way to generate revenue. Rewarded ads, in particular, are effective because they allow players to voluntarily watch an ad in exchange for in-game rewards. Here's a step-by-step guide on how to add rewarded ads to your Unity game using Google AdMob.

1- Set Up Google AdMob Account

• Create an AdMob account if you haven't already.
• Create a new ad unit specifically for rewarded ads.

2- Import Google Mobile Ads Unity Package

• Open your Unity project.
• Download and import the Google Mobile Ads Unity Package.

3- Create C# script for the Rewarded ad.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using GoogleMobileAds;
using GoogleMobileAds.Api;
using System;

public class Rewarded : MonoBehaviour
{
    // These ad units are configured to always serve test ads.
#if UNITY_ANDROID
    private string _adUnitId = "ca-app-pub-3940256099942544/5224354917";
#elif UNITY_IPHONE
  private string _adUnitId = "ca-app-pub-3940256099942544/5224354917";
#else
  private string _adUnitId = "unused";
#endif

    private RewardedAd rewardedAd;
    public void Start()
    {
        

        // Initialize the Google Mobile Ads SDK.
        MobileAds.Initialize((InitializationStatus initStatus) =>
        {
            // This callback is called once the MobileAds SDK is initialized.
            LoadRewardedAd();
        });
    }

    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 AdRequest();
        adRequest.Keywords.Add("unity-admob-sample");

        // 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;
                RegisterEventHandlers(rewardedAd);
            });
    }

    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));
            });
        }
    }

    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.");
            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);

            LoadRewardedAd();
        };
    }


}

If you want to use it in another script add this to the Rewarded last script :

 public static Rewarded Inctance;
    public void Start()
    {
        if (Inctance == null)
        {
            Inctance = this;
        }
        else
        {
            Destroy(this.gameObject);
        }
    }

In the last, To call the rewarded script in another script after or before some events 

write this:-

                Rewarded.Inctance.ShowRewardedAd();

Remember to follow AdMob's policies and guidelines to ensure your ads comply with their rules. Additionally, always test your ads on real devices to ensure a smooth user experience.

That's it! following these steps, you can successfully add rewarded ads to your Unity game.
