Unity游戏实现每5轮/失败后自动播放广告的技术咨询

Hey there! Let's get your ad system working properly—since you're new to Unity and C#, I'll break this down step by step with exact code changes you need to make.

一、先搞定基础配置（这是前提！） #

First off, your AdsManager has placeholder IDs that need to be replaced with real values from your Unity Ads dashboard:

1. Open AdsManager.cs and replace the ####### in gameId with your actual iOS/Android game IDs (they’re different for each platform).
2. Make sure your ad unit IDs (like Interstitial_Android) match exactly what you created in the Unity Ads dashboard—case-sensitive! Update the code to handle both platforms properly:

public void PlayAd()
{
    string adUnitId = "";
#if UNITY_IOS
    adUnitId = "Interstitial_iOS"; // Replace with your iOS interstitial ad ID
#else
    adUnitId = "Interstitial_Android"; // Replace with your Android interstitial ad ID
#endif
    if(Advertisement.IsReady(adUnitId))
        Advertisement.Show(adUnitId);
    else
        Debug.Log("Interstitial ad isn't ready yet!");
}

二、让AdsManager成为单例（避免引用丢失） #

Right now, if your ads reference in GameManager isn’t set correctly in the Inspector, the ad code will fail. Let’s turn AdsManager into a singleton so it’s always accessible:
Add this code to AdsManager.cs at the top of the class, plus an Awake() method:

public class AdsManager : MonoBehaviour, IUnityAdsListener
{
    // Singleton setup
    public static AdsManager Instance;

#if UNITY_IOS
    string gameId = "YOUR_IOS_GAME_ID";
#else
    string gameId = "YOUR_ANDROID_GAME_ID";
#endif

    Action onRewardedAdSuccess;

    void Awake()
    {
        // Ensure only one AdsManager exists across scenes
        if(Instance == null)
        {
            Instance = this;
            DontDestroyOnLoad(gameObject); // Keep this object when switching scenes
        }
        else
        {
            Destroy(gameObject);
        }
    }

    // Rest of your existing code stays the same...
}

三、修复“失败后播放广告”的逻辑 #

Update your GameManager to use the singleton instead of a manual reference, so you don’t have to drag anything in the Inspector:
Modify GameManager.cs:

public class GameManager : MonoBehaviour
{
    public GameObject gameOverCanvas;
    // Remove the old public AdsManager ads; line—we'll use the singleton instead

    private void Start()
    {
        Time.timeScale = 1;
        AdsManager.Instance.ShowBanner(); // Use singleton to show banner
    }

    public void GameOver()
    {
        gameOverCanvas.SetActive(true);
        Time.timeScale = 0;
        AdsManager.Instance.PlayAd(); // Trigger interstitial on game over
    }

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

四、添加“每5轮播放广告”的触发逻辑 #

We’ll add a round counter to GameManager, and trigger an ad whenever the player completes 5 rounds.
Update GameManager.cs with these additions:

public class GameManager : MonoBehaviour
{
    public GameObject gameOverCanvas;
    private int roundCount = 0; // Track how many rounds the player has completed

    private void Start()
    {
        Time.timeScale = 1;
        AdsManager.Instance.ShowBanner();
    }

    // Call this method whenever the player finishes a round!
    // (You'll need to hook this up to your game's round-completion logic)
    public void OnRoundComplete()
    {
        roundCount++;
        if(roundCount >= 5)
        {
            AdsManager.Instance.PlayAd();
            roundCount = 0; // Reset counter after showing ad
        }
    }

    public void GameOver()
    {
        gameOverCanvas.SetActive(true);
        Time.timeScale = 0;
        AdsManager.Instance.PlayAd();
    }

    public void Replay()
    {
        SceneManager.LoadScene(0);
        roundCount = 0; // Reset counter when restarting the game
    }
}

重要：关联轮次完成逻辑 #

找到你游戏中定义“轮次完成”的地方（比如玩家通关关卡、完成一波敌人后），添加下面的代码：

// 示例：在你的Player或LevelManager脚本中
public void FinishRound()
{
    // 你现有的轮次完成逻辑...
    GameManager.Instance.OnRoundComplete(); // 触发广告计数
}

五、测试小贴士 #

• 在Unity中启用测试模式：前往Project Settings > Services > Ads，勾选"Test Mode"，这样会显示测试广告（不会产生真实收益，但测试时避免账户问题）。
• 查看控制台日志：如果广告不显示，找类似"Interstitial ad isn't ready yet"的调试信息或错误日志，它们会告诉你问题所在。
• 确保AdsManager在初始场景中：因为我们加了DontDestroyOnLoad，它会在场景切换时保留下来。
