Unity广告根本不显示，并收到错误'Implement IUnityAdsListener and call Advertisement.AddListener()‘

Question

我在unity中创建了一个非常小的游戏，除了广告的展示之外，一切都做得很好。此外，我没有得到错误，只是一个小警告‘实现IUnityAdsListener并调用Advertisement.AddListener()’。我统一通过了所有的论坛，但它仍然不能在新方法中工作。请帮帮忙。

我的代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.Advertisements;
using UnityEngine.UI;

public class App_Initialize : MonoBehaviour
{
    public GameObject inMenuUI;
    public GameObject inGameUI;
    public GameObject gameoverUI;
    public GameObject adButton;
    public GameObject restartButton;
    public GameObject player;
    public bool hasGameStarted = false;
    private bool hasSeenRewardedAd = false;

    void Awake()
    {
        Shader.SetGlobalFloat("_Curvature", 2.0f);
        Shader.SetGlobalFloat("_Trimming", 0.1f);
        Application.targetFrameRate = 60;
    }
    // Start is called before the first frame update
    void Start()
    {
        player.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.FreezePosition;
        inMenuUI.gameObject.SetActive(true);
        inGameUI.gameObject.SetActive(false);
        gameoverUI.gameObject.SetActive(false);
    }

    public void PlayButton()
    {   
        if(hasGameStarted == true)
        {
            StartCoroutine(StartGame(1.0f));

        }
        else
        {
            StartCoroutine(StartGame(0.0f));
        }
    }

    public void PauseGame()
    {
        player.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.FreezePosition;
        hasGameStarted = true;
        inMenuUI.gameObject.SetActive(true);
        inGameUI.gameObject.SetActive(false);
        gameoverUI.gameObject.SetActive(false);
    }

    public void GameOver()
    {
        player.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.FreezePosition;
        hasGameStarted = true;
        inMenuUI.gameObject.SetActive(false);
        inGameUI.gameObject.SetActive(false);
        gameoverUI.gameObject.SetActive(true);
        if(hasSeenRewardedAd == true)
        {
            adButton.GetComponent<Image>().color = new Color(1, 1, 1, 0.5f);
            adButton.GetComponent<Button>().enabled = false;
            adButton.GetComponent<Animator>().enabled = false;
            restartButton.GetComponent<Animator>().enabled = true;
        }
    }

    public void RestartGame()
    {
        SceneManager.LoadScene(0);
    }

    public void ShowAd()
    {
        if (Advertisement.IsReady("rewardedVideo"))
        {
            var options = new ShowOptions { resultCallback = HandleShowResult };
            Advertisement.Show("rewardedVideo", options);
        }

    }
    private void HandleShowResult(ShowResult result)
    {
        switch (result)
        {
            case ShowResult.Finished:
                Debug.Log("The ad was successfully shown");
                hasSeenRewardedAd = true;
                StartCoroutine(StartGame(1.5f));
                break;
            case ShowResult.Skipped:
                Debug.Log("The ad was skipped before reaching the end");
                break;

            case ShowResult.Failed:
                Debug.LogError("The ad failed to be shown");
                break;
        }
    }

    IEnumerator StartGame(float waitTime)
    {
        inMenuUI.gameObject.SetActive(false);
        inGameUI.gameObject.SetActive(true);
        gameoverUI.gameObject.SetActive(false);
        yield return new WaitForSeconds(waitTime);
        player.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.None;
        player.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.FreezePositionY;
    }

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Escape))
            Application.Quit();
    }
}

首先，您需要将名称空间IUnityAdsListener添加到类中。

public class App_Initialize: MonoBehaviour, IUnityAdsListener {}

接下来，在你的启动函数中添加一个列表器，并用你的gameId和一个布尔testMode初始化Unity Ads。

    void Start()
    {
        Advertisement.AddListener(this);
        Advertisement.Initialize(gameId, testMode);
    }

您将收到一个警告，提示您尚未为IUnityAdsListener实现正确的接口，因此请将这些接口添加到您的脚本中。

    public void OnUnityAdsDidError(string message)
    {
        //YOUR CODE
    }

    public void OnUnityAdsDidFinish(string placementId, ShowResult showResult)
    {
        //YOUR CODE
    }

    public void OnUnityAdsDidStart(string placementId)
    {
        //YOUR CODE
    }

    public void OnUnityAdsReady(string placementId)
    {
        //YOUR CODE
    }

最后，在销毁脚本所在的GameObject或场景时移除侦听器，以避免错误。

private void OnApplicationQuit()
{
    Advertisement.RemoveListener(this);
}
private void OnDestroy()
{
    Advertisement.RemoveListener(this);
}

所以这应该是你的最终结果：

    using UnityEngine;
    using UnityEngine.Advertisements;

    public class App_Initialize : MonoBehaviour, IUnityAdsListener
    {
        public string gameId = "YOUR_GAME_ID";
        public string myPlacementId = "YOUR_PLACEMENT_ID";
        public bool testMode = true;


        void Start()
        {
            Advertisement.AddListener(this);
            Advertisement.Initialize(gameId, testMode);
        }
        private void OnApplicationQuit()
        {
            Advertisement.RemoveListener(this);
        }
        private void OnDestroy()
        {
            Advertisement.RemoveListener(this);
        }
        public void OnUnityAdsDidError(string message)
        {
            //YOUR CODE
        }

        public void OnUnityAdsDidFinish(string placementId, ShowResult showResult)
        {
            //YOUR CODE
        }

        public void OnUnityAdsDidStart(string placementId)
        {
            //YOUR CODE
        }

        public void OnUnityAdsReady(string placementId)
        {
            //YOUR CODE
        }
    }
