Unity - AdMob - Video reward only shows once.

Questions & Answers

Hello… This problem is driving me crazy!

I have implemented AdMob in my game. When I open the ad for the first time, everything works just fine. The second time the ad will only show up (after some clicks on the button), but do not give the reward. When I restart the app, it will work again for one time.

using UnityEngine;
using GoogleMobileAds.Api;
using System;

public class continueGame : MonoBehaviour
{
    public Transform playerspawn;
    public GameObject player;
    public GameObject spawner;

    public static continueGame instance;

    public GameObject[] platform;

    private RewardBasedVideoAd continueAd;
    private string RewardedDummyAdID = "ca-app-pub-3940256099942544/5224354917";

    private void Start()
    {
        continueAd = RewardBasedVideoAd.Instance;
        RequestRewardedAd();

        continueAd.OnAdRewarded += HandleRewardBasedVideoRewarded;
        continueAd.OnAdClosed += HandleRewardBasedVideoClosed;
    }

    public void RequestRewardedAd()
    {
        AdRequest req = new AdRequest.Builder().Build();
        continueAd.LoadAd(req, RewardedDummyAdID);
        
    }


    public void ShowRewardedAd()
    {
        if (!continueAd.IsLoaded())
        {
            AdRequest req = new AdRequest.Builder().Build();
            continueAd.LoadAd(req, RewardedDummyAdID);
            continueAd.Show();

        }
        else
        {
            
            continueAd.Show();
        }
    }

    public void HandleRewardBasedVideoRewarded(object sender, Reward args)
    {
        
        continueTheGame();
        RequestRewardedAd();

    }

    public void HandleRewardBasedVideoClosed(object sender, EventArgs args)
    {
        Debug.Log("Rewarded Video has closed.");
    }
    public void continueTheGame()
    {
        //revive player
        foreach (GameObject go in platform)
        {
            go.SetActive(true);
        }
        player.SetActive(true);
        player.transform.position = playerspawn.position;
        killPlayer.instance.dead = false;
        killPlayer.instance.playerDead = false;
        killPlayer.instance.DeathUI.SetActive(false);
        spawner.SetActive(true);
        spawner.GetComponent<meteorSpawner>().manuelStart();
        spawner.GetComponent<PowerupSpawner>().manuelStart();
        spawner.GetComponent<EnemySpawner>().manuelStart();
        spawner.GetComponent<rocketSpawner>().manuelStart();
        spawner.GetComponent<ammoSpawner>().manuelStart();
        powerups.instance.StartCoroutine("lessknockback");
        gameObject.SetActive(false);
    }

[Solved] You need to unsubscribe from the events

Here is the code snippet

private void OnDestroy()
    {
        // Unsubscribe from reward video event
        rewardBasedVideo.OnAdLoaded -= HandleRewardBasedVideoLoaded;
        rewardBasedVideo.OnAdFailedToLoad -= HandleRewardBasedVideoFailedToLoad;
        rewardBasedVideo.OnAdOpening -= HandleRewardBasedVideoOpened;
        rewardBasedVideo.OnAdStarted -= HandleRewardBasedVideoStarted;
        rewardBasedVideo.OnAdRewarded -= HandleRewardBasedVideoRewarded;
        rewardBasedVideo.OnAdClosed -= HandleRewardBasedVideoClosed;
        rewardBasedVideo.OnAdLeavingApplication -= HandleRewardBasedVideoLeftApplication;
    }
