Unity游戏项目中接入GoogleAdMob

先看效果图

接入测试横幅广告，代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using GoogleMobileAds.Api;
using System;public class GoogleAdMobManager : MonoBehaviour
{private static GoogleAdMobManager _instance;  public static GoogleAdMobManager Instance  {  get  {  if (_instance == null)  {  // 尝试在场景中找到GoogleAdMobManager实例  _instance = FindObjectOfType<GoogleAdMobManager>();  if (_instance == null)  {  Debug.LogError("GoogleAdMobManager instance not found in the scene!");  }  }  return _instance;  }  }  private void Awake()  {  // 确保不会创建GoogleAdMobManager的多个实例  if (_instance != null && _instance != this)  {  Destroy(gameObject);  return;  }  _instance = this;  DontDestroyOnLoad(gameObject); // 防止在加载新场景时销毁此对象（可选）  }  void Start(){MobileAds.Initialize((InitializationStatus initStatus) =>{CreateBannerView();  LoadAd();  ListenToAdEvents(); // LoadInterstitialAd();           });}// Update is called once per framevoid Update(){}#if UNITY_ANDROIDprivate string _adUnitId = "ca-app-pub-3940256099942544/6300978111";
#elif UNITY_IPHONEprivate string _adUnitId = "ca-app-pub-3940256099942544/2934735716";
#elseprivate string _adUnitId = "unused";
#endifBannerView _bannerView;/// <summary>/// Creates a 320x50 banner view at top of the screen./// </summary>public void CreateBannerView(){Debug.Log("Creating banner view");// If we already have a banner, destroy the old one.if (_bannerView != null){DestroyBannerView();}// Create a 320x50 banner at top of the screen_bannerView = new BannerView(_adUnitId, AdSize.Banner, AdPosition.Top);}public void LoadAd()
{// create an instance of a banner view first.if(_bannerView == null){CreateBannerView();}// create our request used to load the ad.var adRequest = new AdRequest();// send the request to load the ad.Debug.Log("Loading banner ad.");_bannerView.LoadAd(adRequest);
}private void ListenToAdEvents()
{// Raised when an ad is loaded into the banner view._bannerView.OnBannerAdLoaded += () =>{Debug.Log("Banner view loaded an ad with response : "+ _bannerView.GetResponseInfo());};// Raised when an ad fails to load into the banner view._bannerView.OnBannerAdLoadFailed += (LoadAdError error) =>{Debug.LogError("Banner view failed to load an ad with error : "+ error);};// Raised when the ad is estimated to have earned money._bannerView.OnAdPaid += (AdValue adValue) =>{Debug.Log(String.Format("Banner view paid {0} {1}.",adValue.Value,adValue.CurrencyCode));};// Raised when an impression is recorded for an ad._bannerView.OnAdImpressionRecorded += () =>{Debug.Log("Banner view recorded an impression.");};// Raised when a click is recorded for an ad._bannerView.OnAdClicked += () =>{Debug.Log("Banner view was clicked.");};// Raised when an ad opened full screen content._bannerView.OnAdFullScreenContentOpened += () =>{Debug.Log("Banner view full screen content opened.");};// Raised when the ad closed full screen content._bannerView.OnAdFullScreenContentClosed += () =>{Debug.Log("Banner view full screen content closed.");};
}public void DestroyBannerView()
{if (_bannerView != null){Debug.Log("Destroying banner view.");_bannerView.Destroy();_bannerView = null;}
}}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using GoogleMobileAds.Api;public class GameMgr : MonoBehaviour
{// Start is called before the first frame updatevoid Start(){}// Update is called once per framevoid Update(){}public void OnPlayButtonClick(){           SceneManager.LoadScene("02-Play");     GoogleAdMobManager.Instance?.DestroyBannerView(); }public void JumpButtonClick(){           SceneManager.LoadScene("03-RewardAd");     }public void OnPauseButtonClick(){//暂停广告//展示广告LoadInterstitialAd();}private InterstitialAd _interstitialAd;  private  string _adUnitId = "ca-app-pub-3940256099942544/1033173712";public void LoadInterstitialAd(){if (_interstitialAd != null){_interstitialAd.Destroy();_interstitialAd = null;} Debug.Log("Loading the interstitial ad.");// InterstitialAd ad = new interstitialAd(_adUnitId);AdRequest adRequest = new AdRequest();InterstitialAd.Load(_adUnitId, adRequest,(InterstitialAd ad, LoadAdError error) =>{// if error is not null, the load request failed.if (error != null || ad == null){Debug.LogError("interstitial ad failed to load an ad " +"with error : " + error);return;}Debug.Log("Interstitial ad loaded with response : "+ ad.GetResponseInfo());_interstitialAd = ad;});ShowInterstitialAd();}public void ShowInterstitialAd()
{if (_interstitialAd != null && _interstitialAd.CanShowAd()){Debug.Log("Showing interstitial ad.");_interstitialAd.Show();}else{Debug.LogError("Interstitial ad is not ready yet.");}
}}

场景1，MainCamera上挂载上面两个脚本，GoogleAdMobManager .cs和 GameMgr.cs

创建StartButton按钮

场景2，加载插屏广告InterstitialAd，Main Camera上挂载Game Mgr.cs

创建Pause Game按钮，当暂停的时候，显示插屏广告，调用Game Mgr.cs中OnPauseButtonClick()方法

创建Jump to reward ad,点击跳转到激励广告。点击JumpButton触发GameMgr中JumpButtonClick()方法。

场景2，02-play中的Main Camera上的Audio Listener需去除，项目场景中只能有一个Audio Listener

场景3，加载激励广告
