在 Unity 中实现奖励广告

对观看广告的玩家进行奖励可以增加用户参与度，从而带来更高收入。例如，游戏可以用游戏币, 消耗品, 额外生命数量或经验倍增法宝来奖励玩家。如需了解如何有效设计奖励广告的更多信息，请参阅有关变现策略的文档。

要奖励玩家看完视频广告，请使用 ShowResult 结果实现一个回调方法来检查用户是否看完广告并应该获得奖励。

奖励广告按钮

使用按钮提示玩家选择观看广告是奖励视频广告的常见实现方式。可使用以下步骤中的示例代码来创建奖励广告按钮。只要有可用的广告内容，就会在按下按钮时展示广告。

要在 Unity 编辑器中配置按钮，请执行以下操作：

1. 选择 Game Object (游戏对象) > UI > Button (按钮)，将按钮添加到您的场景。
2. 选择添加到场景中的按钮，然后使用 Inspector 为其添加脚本组件 (选择 Add Component (添加组件) > New Script (新建脚本))。将脚本命名为 RewardedAdsButton 以便与类名匹配。
3. 打开脚本，并添加以下代码：

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Advertisements;
 
public class RewardedAdsButton : MonoBehaviour, IUnityAdsLoadListener, IUnityAdsShowListener
{
    [SerializeField] Button _showAdButton;
    [SerializeField] string _androidAdUnitId = "Rewarded_Android";
    [SerializeField] string _iOSAdUnitId = "Rewarded_iOS";
    string _adUnitId = null; // This will remain null for unsupported platforms
 
    void Awake()
    {   
        // Get the Ad Unit ID for the current platform:
        #if UNITY_IOS
        _adUnitId = _iOSAdUnitId;
        #elif UNITY_ANDROID
        _adUnitId = _androidAdUnitId;
        #endif

        // Disable the button until the ad is ready to show:
        _showAdButton.interactable = false;
    }
 
    // Call this public method when you want to get an ad ready to show.
    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);
    }
 
    // If the ad successfully loads, add a listener to the button and enable it:
    public void OnUnityAdsAdLoaded(string adUnitId)
    {
        Debug.Log("Ad Loaded: " + adUnitId);
 
        if (adUnitId.Equals(_adUnitId))
        {
            // Configure the button to call the ShowAd() method when clicked:
            _showAdButton.onClick.AddListener(ShowAd);
            // Enable the button for users to click:
            _showAdButton.interactable = true;
        }
    }
 
    // Implement a method to execute when the user clicks the button:
    public void ShowAd()
    {
        // Disable the button:
        _showAdButton.interactable = false;
        // Then show the ad:
        Advertisement.Show(_adUnitId, this);
    }
 
    // Implement the Show Listener's OnUnityAdsShowComplete callback method to determine if the user gets a reward:
    public void OnUnityAdsShowComplete(string adUnitId, UnityAdsShowCompletionState showCompletionState)
    {
        if (adUnitId.Equals(_adUnitId) && showCompletionState.Equals(UnityAdsShowCompletionState.COMPLETED))
        {
            Debug.Log("Unity Ads Rewarded Ad Completed");
            // Grant a reward.
        }
    }
 
    // Implement Load and Show Listener error callbacks:
    public void OnUnityAdsFailedToLoad(string adUnitId, UnityAdsLoadError error, string message)
    {
        Debug.Log($"Error loading Ad Unit {adUnitId}: {error.ToString()} - {message}");
        // Use the error details to determine whether to try to load another ad.
    }
 
    public void OnUnityAdsShowFailure(string adUnitId, UnityAdsShowError error, string message)
    {
        Debug.Log($"Error showing Ad Unit {adUnitId}: {error.ToString()} - {message}");
        // Use the error details to determine whether to try to load another ad.
    }
 
    public void OnUnityAdsShowStart(string adUnitId) { }
    public void OnUnityAdsShowClick(string adUnitId) { }
 
    void OnDestroy()
    {
        // Clean up the button listeners:
        _showAdButton.onClick.RemoveAllListeners();
    }
}
