Implementing rewarded ads in Unity

Rewarding players for watching ads increases user engagement, resulting in higher revenue. For example, games might reward players with in-game currency, consumables, additional lives, or experience-multipliers. For more information on how to effectively design your rewarded ads, refer to the Monetization strategy documentation.

Note: As of SDK version 4.4.1, the Unity Ads package is called Unity Advertisement Legacy. From SDK version 4.4.2 and newer, this package will support only native updates for Android and iOS developers, and will no longer include updates for Unity developers. For more information, refer to the Unity Ads github repository for Android and iOS.

To reward players for completing a video ad, implement a callback method using the ShowResult result to check if the user finished the ad and should be rewarded.

Rewarded ad buttons

Using a button that prompts the player to opt in to watching an ad is a common implementation for rewarded video ads. Use the example code in the following steps to create a rewarded ads button. The button displays an ad when pressed, as long as ad content is available.

To configure a button in the Unity Editor:

Select Game Object > UI > Button to add a button to your Scene.
Select the button you added to your Scene, then add a script component to it using the Inspector (Add Component > New Script). Name the script RewardedAdsButton to match the class name.
Open the script and add the following code:

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

        // Disable the button until the ad is ready to show:
        _showAdButton.interactable = false;
    }
 
    // Call this public method when you want to get an ad ready to show.
    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);
    }
 
    // If the ad successfully loads, add a listener to the button and enable it:
    public void OnUnityAdsAdLoaded(string adUnitId)
    {
        Debug.Log("Ad Loaded: " + adUnitId);
 
        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;
        }
    }
 
    // 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);
    }
 
    // 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.
        }
    }
 
    // 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();
    }
}
