Unity MobAd奖励视频不起作用

如何解决Unity MobAd奖励视频不起作用

我有一个奇怪的问题。我已经在游戏中实现了广告代码，当玩家死亡时，我要求玩家观看广告并重生。当我将apk构建并安装到手机上时，在第一次播放时，一切都运行良好。在第二次尝试之后，我的rewarderAdd.OnAdRewarded函数根本不起作用。我在游戏和第二局中控制广告状态，我可以看到奖励系统没有运行。这是我的代码

  void Start()
    {
        adState = 0;
        gameOverScript = GameObject.Find("GameOver").GetComponent<GameOverCode>();
        kingSCript = GameObject.FindGameObjectWithTag("Player").GetComponent<RedKing>();
        isCompleted = false;
        RequestRewardedVideo();
        this.rewardedAd.OnAdRewarded += Rewardplayer;
       // this.rewardedAd.OnAdClosed += PlayerClosed;


    }

    public void RequestRewardedVideo()
    {
        rewardedAd = RewardBasedVideoAd.Instance;
        // Create an empty ad request.
        AdRequest request = new AdRequest.Builder().Build();
        // Load the rewarded ad with the request.
        this.rewardedAd.LoadAd(request,rewarderID);
        if(rewardedAd.IsLoaded() == true)
        {
            adState = 5;
        }


    }
    private void Rewardplayer(object sender,EventArgs e)
    {
        isCompleted = true;
        adState = 1;
        Reward();
    }

    private void PlayerClosed(object sender,EventArgs e)
    {
        if(adState != 1)
        {
            adState = -1;
        }
    }


    public void Reward()
    {
        adState = 1;
        kingSCript.Reborn();
    }
    public void ShowVideoRewardAd()
    {
        if (this.rewardedAd.IsLoaded())
        {
            adState = 2;
            isLoaded = true;
            this.rewardedAd.Show();
        }
        else
        {
            isLoaded = false;
        }
    }

为什么广告状态在第二次尝试后无法正常工作？每次我重新上传场景时，每个代码都应该像第一次一样工作，但根本不工作！

解决方法

解决方案是对所有方法使用-=函数。检查此脚本

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

link = 'https://www.usdebtclock.org/world-debt-clock.html'
results = []

with webdriver.Chrome() as driver:

    wait = WebDriverWait(driver,10)
    driver.get(link)

    current_row = []
    found_first_percent = False

    for elem in wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR,"[id^='layer'] > span"))):
        current_row.append(elem)
        if "%" in elem:
            if found_first_percent:
                results.append(current_row)
                current_row = []
                found_first_percent = False
            else:
                found_first_percent = True

for row in results:
    print(row)
