Unity集成Google Play Games：成就与排行榜无法更新问题

问题详情 #

我在Unity开发的游戏里集成Google Play Games实现成就和排行榜功能，按教程完成配置并调整代码后，运行时顶部能显示Google Play Games个人资料，但成就和排行榜数据无法更新。排查后在Android Logcat中发现提交排行榜时出现以下错误：

        Social.ReportProgress(id, wartosc, (bool success) =>
        {
            if (success)
            {
                Debug.Log("Score Update");
            }
        });
    }

    public void LeaderBoard(string id, int wartosc)
    {
        Social.ReportScore(wartosc, id, (bool success) =>
        {
            if (success)
            {
                Debug.Log("Score Update");
            }
            else
            {
                Debug.Log("Nie udało się przesłać");
            }
        });
    }
}

解决方案 #

1. 绑定Social平台到PlayGamesPlatform #

Unity的Social类默认未关联Google Play Games平台，初始化时需要显式激活并绑定：

public void Start()
{
    // 激活PlayGamesPlatform并设置为Social的实现
    PlayGamesPlatform.Activate();
    PlayGamesPlatform.Instance.Authenticate(ProcessAuthentication);
}

2. 校验认证状态后再上报数据 #

报错核心原因是调用成就/排行榜接口时，用户未完成认证。添加状态标记，确保只有认证成功后才允许上报：

private bool isAuthenticated = false;

internal void ProcessAuthentication(SignInStatus status)
{
    if (status == SignInStatus.Success)
    {
        isAuthenticated = true;
        // 原有其他代码...
    }
    else
    {
        isAuthenticated = false;
        // 原有其他代码...
    }
}

public void Osiagniecie(string id, int wartosc)
{
    if (!isAuthenticated)
    {
        Debug.LogError("用户未认证，无法提交成就");
        return;
    }
    Social.ReportProgress(id, wartosc, (bool success) =>
    {
        if (success)
        {
            Debug.Log("成就提交成功");
        }
        else
        {
            Debug.Log("成就提交失败");
        }
    });
}

public void LeaderBoard(string id, int wartosc)
{
    if (!isAuthenticated)
    {
        Debug.LogError("用户未认证，无法提交排行榜分数");
        return;
    }
    Social.ReportScore(wartosc, id, (bool success) =>
    {
        if (success)
        {
            Debug.Log("分数提交成功");
        }
        else
        {
            Debug.Log("分数提交失败");
        }
    });
}

3. 处理异步认证的时序问题 #

RequestServerSideAccess是异步操作，若你的SignInWithGoogleAsync涉及额外服务器认证，需确保这部分完成后再触发上报逻辑；如果不需要服务器端访问，可暂时注释该代码块，先测试基础功能是否正常。

4. 验证Google Play Console配置 #

• 确认游戏已关联正确的OAuth客户端ID
• 确认成就、排行榜ID与代码中使用的完全一致
• 测试账号已添加到Google Play Console的测试账号列表中
