如何在 Steamworks.NET 中制作排行榜？

Question

我正在尝试在我的应用程序（用 C# 编写，使用 SteamWorks.NET 并基于 XNA 的游戏）中包含排行榜。

Steam 已正确初始化。

在游戏开始时我会调用：

SteamAPICall_t hSteamAPICall = SteamUserStats.FindLeaderboard("Most active beta testers");
leaderboard_BetaTesters_ResultFindLeaderboard = Callback<LeaderboardFindResult_t>.Create(OnLeaderboardFindResult_BetaTesters);

使用

static private void OnLeaderboardFindResult_BetaTesters(LeaderboardFindResult_t pCallback)
{
// See if we encountered an error during the call
if (pCallback.m_bLeaderboardFound == 0)
  {
  Warning.Happened("Leaderboard could not be found / accessed");
  return;
  }
else
  {
  Write.Text("Steam leaderboad connected");
  }
  leaderboard_BetaTesters = pCallback.m_hSteamLeaderboard;
}

在我调用的每个 Update() 中：

if (SystemLogic.SteamInitSuccessul()) SteamAPI.RunCallbacks();

但是，永远不会调用 OnLeaderboardFindResult_BetaTesters。我做错了什么？

我知道这是一个老问题，但我现在也有同样的问题。

当我尝试使用 Steamworks.NET 在 Unity 上实现 Steam 排行榜时，我遇到了同样的问题。 最后，我从原始的 Steamworks C++ 示例项目中得到了它。 （Steamworks.NET 的文档真的很差，就像原来的 Steamworks c++ 一样，所以你必须查看 Steamworks c++ 示例项目以了解如何使用它）

你有一个错误，你必须使用“CallResult”类而不是“Callback”类。

以下代码允许我将 Unity 上的分数上传到 SteamLeaderboard：

using UnityEngine;
using Steamworks;
using System.Collections;
using System.Threading;

public class SteamLeaderboards : MonoBehaviour
{
    private const string s_leaderboardName = "StoryMode";
    private const ELeaderboardUploadScoreMethod s_leaderboardMethod = ELeaderboardUploadScoreMethod.k_ELeaderboardUploadScoreMethodKeepBest;

    private static SteamLeaderboard_t s_currentLeaderboard;
    private static bool s_initialized = false;
    private static CallResult<LeaderboardFindResult_t> m_findResult = new CallResult<LeaderboardFindResult_t>();
    private static CallResult<LeaderboardScoreUploaded_t> m_uploadResult = new CallResult<LeaderboardScoreUploaded_t>();


    public static void UpdateScore(int score)
    {
        if (!s_initialized)
        {
            UnityEngine.Debug.Log("Can't upload to the leaderboard because isn't loadded yet");
        }
        else
        {
            UnityEngine.Debug.Log("uploading score(" + score + ") to steam leaderboard(" + s_leaderboardName + ")");
            SteamAPICall_t hSteamAPICall = SteamUserStats.UploadLeaderboardScore(s_currentLeaderboard, s_leaderboardMethod, score, null, 0);
            m_uploadResult.Set(hSteamAPICall, OnLeaderboardUploadResult);
        }
    }

    public static void Init()
    {
        SteamAPICall_t hSteamAPICall = SteamUserStats.FindLeaderboard(s_leaderboardName);
        m_findResult.Set(hSteamAPICall, OnLeaderboardFindResult);
        InitTimer();
    }

    static private void OnLeaderboardFindResult(LeaderboardFindResult_t pCallback, bool failure)
    {
        UnityEngine.Debug.Log("STEAM LEADERBOARDS: Found - " + pCallback.m_bLeaderboardFound + " leaderboardID - " + pCallback.m_hSteamLeaderboard.m_SteamLeaderboard);
        s_currentLeaderboard = pCallback.m_hSteamLeaderboard;
        s_initialized = true;
    }

    static private void OnLeaderboardUploadResult(LeaderboardScoreUploaded_t pCallback, bool failure)
    {
        UnityEngine.Debug.Log("STEAM LEADERBOARDS: failure - " + failure + " Completed - " + pCallback.m_bSuccess + " NewScore: " + pCallback.m_nGlobalRankNew + " Score " + pCallback.m_nScore + " HasChanged - " + pCallback.m_bScoreChanged);
    }



    private static Timer timer1; 
    public static void InitTimer()
    {
        timer1 = new Timer(timer1_Tick, null,0,1000);
    }

    private static void timer1_Tick(object state)
    {
        SteamAPI.RunCallbacks(); 
    }
}

*这段代码我已经编辑了好几次，没有编译，可能包含任何语法错误，但实现应该没问题

** 另请记住，此代码已在 Unity 4 上使用，但 Unity 类仅用于“控制台日志”消息和最后两个方法“每 x 毫秒调用 SteamAPI.RunCallbacks() 方法”
