Unity rewarded video ads

- In this tutorial we will integrate multiple reward ads.

 Note : if you don't know how to activate Unity ads monetization Clock Here .

UNity Advertisement Version SDK 4 or higher

Exemple for two Rewarded Ads:
  • First create 2 Unity ads Id in unity Dashboard to us it in your Script.
  • create 2 button for your reward ads:

Unity rewarded video ads

Unity Ads script , Unity rewarded video ads

  • Now you must create a script to initialize the  unity Advertisement " AdsInitializer "

Copy the script:

using UnityEngine;
using UnityEngine.Advertisements;
 
public class AdsInitializer : MonoBehaviour, IUnityAdsInitializationListener
{
    [SerializeField] string _androidGameId;
    [SerializeField] string _iOSGameId;
    [SerializeField] bool _testMode = true;
    private string _gameId;

    [SerializeField] RewardedAds rewardedAds;
   
 
    void Awake()
    {
        InitializeAds();
    }
 
    public void InitializeAds()
    {
        _gameId = (Application.platform == RuntimePlatform.IPhonePlayer)
            ? _iOSGameId
            : _androidGameId;
        Advertisement.Initialize(_gameId, _testMode, this);
    }
 
    public void OnInitializationComplete()
    {
        Debug.Log("Unity Ads initialization complete.");
        rewardedAds.LoadAd();

    }
 
    public void OnInitializationFailed(UnityAdsInitializationError error, string message)
    {
        Debug.Log($"Unity Ads Initialization Failed: {error.ToString()} - {message}");
    }
}


  • Create the script for the Rewarded ads " RewardedAds  "
  • Copy the script ;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Advertisements;

public class RewardedAds : MonoBehaviour, IUnityAdsLoadListener, IUnityAdsShowListener
{
    [SerializeField] Button _showAdButton;
    [SerializeField] Button _showAdButton2;
    [SerializeField] string _androidAdUnitId = "Rewarded_Android";
    [SerializeField] string _androidAdUnitId2 = "Rewarded_Android2";
    [SerializeField] string _iOSAdUnitId = "Rewarded_iOS";
    string _adUnitId = null; // This will remain null for unsupported platforms
    string _adUnitId2 = null;
 
    void Awake()
    {  
        // Get the Ad Unit ID for the current platform:
#if UNITY_IOS
        _adUnitId = _iOSAdUnitId;
#elif UNITY_ANDROID
        _adUnitId = _androidAdUnitId;
        _adUnitId2 = _androidAdUnitId2;
#endif

        //Disable the button until the ad is ready to show:
        _showAdButton.interactable = false;
        _showAdButton2.interactable = false;
    }
 
    // Load content to the Ad Unit:
    public void LoadAd()
    {
        // IMPORTANT! Only load content AFTER initialization (in this example, initialization is handled in a different script).
        Debug.Log("Loading Ad: " + _adUnitId);
        Advertisement.Load(_adUnitId, this);

        Debug.Log("Loading Ad: " + _adUnitId2);
        Advertisement.Load(_adUnitId2, this);
    }
 
    // If the ad successfully loads, add a listener to the button and enable it:
    public void OnUnityAdsAdLoaded(string adUnitId)
    {
        Debug.Log("Ad Loaded: " + adUnitId);
           
//// Button 1 ////
        if (adUnitId.Equals(_adUnitId))
        {

            // Configure the button to call the ShowAd() method when clicked:
            _showAdButton.onClick.AddListener(ShowAd);
            // Enable the button for users to click:
            _showAdButton.interactable = true;

           
        }


        /// ad 2 ////        
        if (adUnitId.Equals(_adUnitId2))
        {
 
            // Configure the button to call the ShowAd() method when clicked:
            _showAdButton2.onClick.AddListener(ShowAd2);
            // Enable the button for users to click:
            _showAdButton2.interactable = true;
        }
    }

    public void OnUnityAdsAdLoaded2(string adUnitId2)
    {
       
    }
 
    // Implement a method to execute when the user clicks the button:
    public void ShowAd()
    {
        // Disable the button:
        _showAdButton.interactable = false;
        // Then show the ad:
        Advertisement.Show(_adUnitId, this);
    }
    public void ShowAd2()
    {
        // Disable the button:
        _showAdButton2.interactable = false;
        // Then show the ad:
        Advertisement.Show(_adUnitId2, this);
    }
 
    // Implement the Show Listener's OnUnityAdsShowComplete callback method to determine if the user gets a reward:
    public void OnUnityAdsShowComplete(string adUnitId, UnityAdsShowCompletionState showCompletionState)
    {
        if (adUnitId.Equals(_adUnitId) && showCompletionState.Equals(UnityAdsShowCompletionState.COMPLETED))
        {
            Debug.Log("Unity Ads Rewarded Ad Completed");
            // Grant a reward.
            Debug.Log("you get reward");

            // Load another ad:
            Advertisement.Load(_adUnitId, this);
        }

        if (adUnitId.Equals(_adUnitId2) && showCompletionState.Equals(UnityAdsShowCompletionState.COMPLETED))
        {
            Debug.Log("Unity Ads Rewarded Ad Completed");
            // Grant a reward.
            Debug.Log("you get reward 2 ");

            // Load another ad:
            Advertisement.Load(_adUnitId2, this);
        }
    }
 
    // Implement Load and Show Listener error callbacks:
    public void OnUnityAdsFailedToLoad(string adUnitId, UnityAdsLoadError error, string message)
    {
        Debug.Log($"Error loading Ad Unit {adUnitId}: {error.ToString()} - {message}");
        // Use the error details to determine whether to try to load another ad.
    }
 
    public void OnUnityAdsShowFailure(string adUnitId, UnityAdsShowError error, string message)
    {
        Debug.Log($"Error showing Ad Unit {adUnitId}: {error.ToString()} - {message}");
        // Use the error details to determine whether to try to load another ad.
    }
 
    public void OnUnityAdsShowStart(string adUnitId) { }
    public void OnUnityAdsShowClick(string adUnitId) { }
 
    void OnDestroy()
    {
        // Clean up the button listeners:
        _showAdButton.onClick.RemoveAllListeners();
        _showAdButton2.onClick.RemoveAllListeners();
    }
}

  • Save all and go to unity editor.
  • create a new Game object , name it  "AdsManager "


Unity Ads code

  • add the two scripts and fill the details:
Unity rewarded video ads

Now your Ads are ready .

For preview UNity Advertisement  SDK Version:

  • After creating two reawaded unity ad Id make a new script to manage the video rewarded ads.
  •  Name it " UnityAdsGetReward " , copy past the below Script .



  • UnityAdsGetReward.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Advertisements;

public class UnityAdsGetReward : MonoBehaviour, IUnityAdsListener
{
    string gameID = "0000000";
   
   
    string rewardedAdName = "Rewarded_Android";
   

    string hitAdName = "hint";


    bool rewarded = false;
    public bool testMode = false;
    public static UnityAdsGetReward instance;

   
private void Awake()
{
    if(instance == null)
    {
        instance = this;
    }
}
    // Start is called before the first frame update
    void Start()
    {
        Advertisement.AddListener(this);
        Advertisement.Initialize(gameID, testMode);
       
    }

    public void OnInitializationComplete()
    {
        Debug.Log("Unity Ads initialization complete.");
    }
 
    public void OnInitializationFailed(UnityAdsInitializationError error, string message)
    {
        Debug.Log($"Unity Ads Initialization Failed: {error.ToString()} - {message}");
    }


    public void ShowRewardedVideo()
    {
        // Check if UnityAds ready before calling Show method:
        if (Advertisement.IsReady(rewardedAdName))
        {
            Advertisement.Show(rewardedAdName);
        }
        else
        {
           
            Debug.Log("Video is not ready yet");
            Debug.Log("Rewarded video is not ready at the moment! Please try again later!");
        }
    }

   
    public void ShowHintdVideo()
    {
        // Check if UnityAds ready before calling Show method:
        if (Advertisement.IsReady(hitAdName))
        {
            Advertisement.Show(hitAdName);
        }
        else
        {
           

            Debug.Log(" Hit Video is not ready yet");
            Debug.Log("Rewarded video is not ready at the moment! Please try again later!");
        }
    }

    // Implement IUnityAdsListener interface methods:
    public void OnUnityAdsDidFinish(string placementId, ShowResult showResult)
    {
        // Define conditional logic for each ad completion status:
        if (placementId == "Rewarded_Android" && showResult == ShowResult.Finished)
        {
           
            // Reward the user for watching the ad to completion.
           
           
       
        }
        if (placementId == "hint" && showResult == ShowResult.Finished)
        {
           
            // Reward the user for watching the ad to completion.
           
           
        }



        else if (showResult == ShowResult.Skipped)
        {
            // Do not reward the user for skipping the ad.
        }
        else if (showResult == ShowResult.Failed)
        {
            Debug.LogWarning("The ad did not finish due to an error.");
        }
    }

    public void OnUnityAdsReady(string placementId)
    {
        // If the ready Placement is rewarded, show the ad:
        if (placementId == rewardedAdName)
        {
            // Optional actions to take when the placement becomes ready(For example, enable the rewarded ads button)
        }
    }

    public void OnUnityAdsDidError(string message)
    {
        // Log the error.
    }

    public void OnUnityAdsDidStart(string placementId)
    {
        // Optional actions to take when the end-users triggers an ad.
    }

    // When the object that subscribes to ad events is destroyed, remove the listener:
    public void OnDestroy()
    {
        Advertisement.RemoveListener(this);
    }
}

  • Change the parts marked in red with the information for your ad units :

string gameID = "0000000";
   
   
string rewardedAdName = "Rewarded_Android";
   

string hitAdName = "hint";

 

  • Put the code for the reward in the place marked in green :
// Implement IUnityAdsListener interface methods:
    public void OnUnityAdsDidFinish(string placementId, ShowResult showResult)
    {
        // Define conditional logic for each ad completion status:
        if (placementId == "Rewarded_Android" && showResult == ShowResult.Finished)
        {
            
            // Reward the user for watching the ad to completion.
                           
        }
        if (placementId == "hint" && showResult == ShowResult.Finished)
        {
            
            // Reward the user for watching the ad to completion.
                       
        }
