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

Starting from SDK version 4.4.1, the Unity Ads package is now called the Advertisement Legacy package in the Unity Editor. The Advertisement Legacy package version 4.12 is still functional but will not receive any further updates for new or enhanced features. SDK version 4.12 supports the Apple Privacy Manifest update, with no further updates planned for the package.

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.

Rewarded video ad example

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();  }}
