在 Unity 中实现插页式广告

要使用 Advertisements API 来展示全屏插页式广告，请初始化 SDK，然后使用 Load 函数将广告内容加载到广告单元中，并使用 Show 函数展示广告。

在 SDK 3.7.0 及更高版本中，可以使用 IUnityAdsLoadListener 和 IUnityAdsShowListener 回调分别实现内容加载或展示成功或失败的逻辑。

using UnityEngine;
using UnityEngine.Advertisements;
 
public class InterstitialAdExample : MonoBehaviour, IUnityAdsLoadListener, IUnityAdsShowListener
{
    [SerializeField] string _androidAdUnitId = "Interstitial_Android";
    [SerializeField] string _iOsAdUnitId = "Interstitial_iOS";
    string _adUnitId;
 
    void Awake()
    {
        // Get the Ad Unit ID for the current platform:
        _adUnitId = (Application.platform == RuntimePlatform.IPhonePlayer)
            ? _iOsAdUnitId
            : _androidAdUnitId;
    }
 
    // Load content to the Ad Unit:
    public void LoadAd()
    {
        // IMPORTANT! Only load content AFTER initialization (in this example, initialization is handled in a different script).
        Debug.Log("Loading Ad: " + _adUnitId);
        Advertisement.Load(_adUnitId, this);
    }
 
    // Show the loaded content in the Ad Unit:
    public void ShowAd()
    {
        // Note that if the ad content wasn't previously loaded, this method will fail
        Debug.Log("Showing Ad: " + _adUnitId);
        Advertisement.Show(_adUnitId, this);
    }
 
    // Implement Load Listener and Show Listener interface methods: 
    public void OnUnityAdsAdLoaded(string adUnitId)
    {
        // Optionally execute code if the Ad Unit successfully loads content.
    }
 
    public void OnUnityAdsFailedToLoad(string _adUnitId, UnityAdsLoadError error, string message)
    {
        Debug.Log($"Error loading Ad Unit: {_adUnitId} - {error.ToString()} - {message}");
        // Optionally execute code if the Ad Unit fails to load, such as attempting to try again.
    }
 
    public void OnUnityAdsShowFailure(string _adUnitId, UnityAdsShowError error, string message)
    {
        Debug.Log($"Error showing Ad Unit {_adUnitId}: {error.ToString()} - {message}");
        // Optionally execute code if the Ad Unit fails to show, such as loading another ad.
    }
 
    public void OnUnityAdsShowStart(string _adUnitId) { }
    public void OnUnityAdsShowClick(string _adUnitId) { }
    public void OnUnityAdsShowComplete(string _adUnitId, UnityAdsShowCompletionState showCompletionState) { }
}
