In Nathan’s new lecture, with the updated to the latest version of Unity Ads, there is a change to the workflow from the previous versions of the Lectures.
Specifically, ads must be Loaded before they can be Shown.
This leads to an AdManager that looks like this:
AdManager.cs course repo
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Advertisements;
public class AdManager : MonoBehaviour, IUnityAdsInitializationListener, IUnityAdsLoadListener, IUnityAdsShowListener
{
[SerializeField] private string androidGameId;
[SerializeField] private string iOSGameId;
[SerializeField] private bool testMode = true;
[SerializeField] private string androidAdUnitId;
[SerializeField] private string iOSAdUnitId;
public static AdManager Instance;
private string gameId;
private string adUnitId;
private GameOverHandler gameOverHandler;
private void Awake()
{
if (Instance != null && Instance != this)
{
Destroy(gameObject);
}
else
{
InitialiseAds();
Instance = this;
DontDestroyOnLoad(gameObject);
}
}
private void InitialiseAds()
{
#if UNITY_IOS
gameId = iOSGameId;
adUnitId = iOSAdUnitId;
#elif UNITY_ANDROID
gameId = androidGameId;
adUnitId = androidAdUnitId;
#elif UNITY_EDITOR
gameId = androidGameId;
adUnitId = androidAdUnitId;
#endif
if (!Advertisement.isInitialized)
{
Advertisement.Initialize(gameId, testMode, this);
}
}
public void OnInitializationComplete()
{
Debug.Log("Unity Ads initialization complete.");
}
public void OnInitializationFailed(UnityAdsInitializationError error, string message)
{
Debug.Log($"Unity Ads Initialization Failed: {error.ToString()} - {message}");
}
public void OnUnityAdsAdLoaded(string placementId)
{
Advertisement.Show(placementId, this);
}
public void OnUnityAdsFailedToLoad(string placementId, UnityAdsLoadError error, string message)
{
Debug.Log($"Error loading Ad Unit {adUnitId}: {error.ToString()} - {message}");
}
public void OnUnityAdsShowFailure(string placementId, UnityAdsShowError error, string message)
{
Debug.Log($"Error showing Ad Unit {adUnitId}: {error.ToString()} - {message}");
}
public void OnUnityAdsShowStart(string placementId)
{
}
public void OnUnityAdsShowClick(string placementId)
{
}
public void OnUnityAdsShowComplete(string placementId, UnityAdsShowCompletionState showCompletionState)
{
if (placementId.Equals(adUnitId)
&& showCompletionState.Equals(UnityAdsShowCompletionState.COMPLETED))
{
gameOverHandler.ContinueGame();
}
}
public void ShowAd(GameOverHandler gameOverHandler)
{
this.gameOverHandler = gameOverHandler;
Advertisement.Load(adUnitId, this);
}
}
After further research, the recommended workflow is to Load and ad as soon as the Initialization is complete, and then as soon as an ad is finished in ShowAdComplete, Load another one. This ensures that an Ad is ready to go as soon as you call for it.
I’ve made some small modifications to the script that actually takes into account that an ad may not be loaded when you need to show one. It adds a couple of boolean values to track if an ad is loaded, and if we are waiting to show an ad.
Revised AdManager.cs

}

InitialiseAds();

DontDestroyOnLoad(gameObject);
}
