以下是一个基于Mirror的多人连接管理及房间系统的服务端实现方案，包含部署说明：

一、服务端架构设计

  1. 网络管理扩展

    using Mirror;
    using UnityEngine;

    public class RoomNetworkManager : NetworkManager
    {
    // 房间字典（房间ID -> 房间对象）
    public static Dictionary<string, Room> rooms = new Dictionary<string, Room>();

    复制代码 
     public override void OnServerConnect(NetworkConnection conn)
 {
     base.OnServerConnect(conn);
     Debug.Log($"客户端 {conn.connectionId} 已连接");
 }

 public override void OnServerDisconnect(NetworkConnection conn)
 {
     // 处理玩家断开逻辑
     var player = conn.identity.GetComponent<NetworkPlayer>();
     if (player != null && player.CurrentRoom != null)
     {
         player.CurrentRoom.RemovePlayer(player);
     }
     
     base.OnServerDisconnect(conn);
     Debug.Log($"客户端 {conn.connectionId} 已断开");
 }

    }

复制代码

  1. 房间类实现

    public class Room
    {
    public string RoomID { get; } = Guid.NewGuid().ToString().Substring(0, 8);
    public string RoomName { get; set; }
    public int MaxPlayers { get; } = 4;
    public bool IsPlaying { get; set; }

    复制代码 
     public List<NetworkPlayer> Players { get; } = new List<NetworkPlayer>();
 public NetworkPlayer Host => Players.FirstOrDefault();

 public bool AddPlayer(NetworkPlayer player)
 {
     if (Players.Count >= MaxPlayers || IsPlaying) return false;
     
     Players.Add(player);
     player.CurrentRoom = this;
     player.RpcJoinRoomSuccess(RoomID);
     UpdateAllPlayers();
     return true;
 }

 public void RemovePlayer(NetworkPlayer player)
 {
     Players.Remove(player);
     player.CurrentRoom = null;
     UpdateAllPlayers();
     
     if (Players.Count == 0)
     {
         RoomNetworkManager.rooms.Remove(RoomID);
     }
 }

 private void UpdateAllPlayers()
 {
     foreach (var p in Players)
     {
         p.RpcUpdateRoomInfo(GetRoomInfo());
     }
 }

 public RoomInfo GetRoomInfo() => new RoomInfo
 {
     roomId = RoomID,
     playerCount = Players.Count,
     hostName = Host?.PlayerName
 };

    }

复制代码

  1. 玩家网络对象

    public class NetworkPlayer : NetworkBehaviour
    {
    [SyncVar] public string PlayerName;
    [SyncVar] public bool IsReady;
    public Room CurrentRoom;

    复制代码 
     [Command]
 public void CmdCreateRoom(string roomName)
 {
     Room newRoom = new Room { RoomName = roomName };
     RoomNetworkManager.rooms.Add(newRoom.RoomID, newRoom);
     newRoom.AddPlayer(this);
 }

 [Command]
 public void CmdJoinRoom(string roomId)
 {
     if (RoomNetworkManager.rooms.TryGetValue(roomId, out Room room))
     {
         if (!room.AddPlayer(this))
         {
             TargetJoinRoomFailed("房间已满或游戏已开始");
         }
     }
     else
     {
         TargetJoinRoomFailed("房间不存在");
     }
 }

 [TargetRpc]
 public void TargetJoinRoomFailed(string reason) { /* 客户端处理 */ }

 [Command]
 public void CmdStartGame()
 {
     if (CurrentRoom.Host != this) return;
     CurrentRoom.IsPlaying = true;
     ServerChangeScene("GameScene");
 }

    }

复制代码

二、部署流程

  1. 服务器构建

    使用Headless模式构建Linux服务器

    Unity.exe -batchmode -nographics -buildTarget Linux64 -buildPath ServerBuild -quit

复制代码

  1. 服务器配置

    // NetworkManager配置
    public class ServerConfig : MonoBehaviour
    {
    void Start()
    {
    // 设置服务器参数
    Transport.activeTransport = GetComponent();
    GetComponent().networkAddress = "0.0.0.0";
    GetComponent().StartServer();
    }
    }

复制代码
  1. **网络要求

  • 开放端口：7777（默认TCP/UDP）

  • 建议使用固定公网IP或DDNS

  • 推荐服务器配置：

    • 最低：2核CPU / 4GB RAM（支持50人同时在线）

    • 推荐：4核CPU / 8GB RAM（支持200人同时在线）

三、客户端交互示例

  1. 创建房间

    public void CreateRoom(string roomName)
    {
    NetworkClient.localPlayer.GetComponent().CmdCreateRoom(roomName);
    }

复制代码

  1. 加入房间

    public void JoinRoom(string roomId)
    {
    NetworkClient.localPlayer.GetComponent().CmdJoinRoom(roomId);
    }

复制代码

四、优化建议

  1. 心跳检测

    // 添加心跳机制防止假连接
    [System.Serializable]
    public class HeartbeatConfig
    {
    public float Interval = 5f;
    public float Timeout = 15f;
    }

复制代码

  1. 房间清理

    void CleanEmptyRooms()
    {
    var emptyRooms = rooms.Values.Where(r => r.Players.Count == 0).ToList();
    foreach (var room in emptyRooms)
    {
    rooms.Remove(room.RoomID);
    }
    }

复制代码

五、安全措施

  1. 数据验证

    [Command]
    public void CmdSendChat(string message)
    {
    // 防止注入攻击
    if (message.Length > 100) return;
    if (message.Contains("
