弄个 Server.js 挂到 场景一：
---------------------------------------------------------------------------------------------------------
var connectToIP : String = "127.0.0.1";
var connectPort : int = 2224;


function OnGUI ()
{
    if (Network.peerType == NetworkPeerType.Disconnected)
    {
        GUILayout.Label("Connection status: Disconnected");
  
        connectToIP = GUILayout.TextField(connectToIP, GUILayout.MinWidth(100));
        connectPort = parseInt(GUILayout.TextField(connectPort.ToString()));
  
        if (GUILayout.Button("Start Server"))
        {
            Network.InitializeServer(32, connectPort, false);
        }
    }
    else
    {
        if (Network.peerType == NetworkPeerType.Server)
        {
            GUILayout.Label("Connection status: Server!");
            GUILayout.Label("Connection: " + Network.connections.length);
            if (Network.connections.length >= 1)
            {
                GUILayout.Label(&quoting to first player: " + Network.GetAveragePing(Network.connections[0]));
            }
        }
  
        if (GUILayout.Button("Disconnect"))
        {
            Network.Disconnect(200);
        }
    }
}


// Server functions called by Unity
function OnPlayerConnected(player: NetworkPlayer) {
    Debug.Log("Player connected from: " + player.ipAddress + ":" + player.port);
}


function OnServerInitialized() {
    Debug.Log("Server initialized and ready");
}


function OnPlayerDisconnected(player: NetworkPlayer) {
    Debug.Log("Player disconnected from: " + player.ipAddress + ":" + player.port);
}
---------------------------------------------------------------------------------------------------------


弄个 Client.js 挂到场景二：
---------------------------------------------------------------------------------------------------------


var connectToIP : String = "127.0.0.1";
var connectPort : int = 2224;


function OnGUI ()
{
    if (Network.peerType == NetworkPeerType.Disconnected)
    {
        GUILayout.Label("Connection status: Disconnected");
  
        connectToIP = GUILayout.TextField(connectToIP, GUILayout.MinWidth(100));
        connectPort = parseInt(GUILayout.TextField(connectPort.ToString()));
  
        if (GUILayout.Button("Connect as client"))
        {
            Network.Connect(connectToIP, connectPort);
        }
    }
    else
    {
        if (Network.peerType == NetworkPeerType.Connecting)
        {
            GUILayout.Label("Connection status: Connecting");
        }
        else if (Network.peerType == NetworkPeerType.Client)
        {
            GUILayout.Label("Connection status: Client!");
            GUILayout.Label("Ping to server: " + Network.GetAveragePing(Network.connections[0]));
        }
  
        if (GUILayout.Button("Disconnect"))
        {
            Network.Disconnect(200);
        }
    }
}


// Client functions called by Unity
function OnConnectedToServer()
{
    Debug.Log("This CLIENT has connected to a server");
}


function OnDisconnectedFromServer(info : NetworkDisconnection)
{
    Debug.Log("This SERVER OR CLIENT has disconnected from a server");
}


function OnFailedToConnect(error: NetworkConnectionError)
{
    Debug.Log("Could not connect to server: " + error);
}
---------------------------------------------------------------------------------------------------------


把 ClientScene 放到 webplayer 上，然后 ServerScene 在 unity editor 里面直接跑。然后就可以本机测试了。
在 ServerScene 跑之前，设置 Edit => Project Settings => Player 中的 Run In Background。因为默认处于 inactive window 状态的 Unity程序会去 sleep，如果不设置 "Run In Background"，则在操作 ClientScene 时，你会发现连接不上服务器，但点一下 ServerScene，然后再看 ClientScene 就连接上了。


Unity 对网络事件的封装还是很到位的。
不过目前看起来，其不允许你用 Unity 的客户端连接自己的服务器。这个还要继续研究。

自己打造 u3d 网络层，给 u3d 客户端写个插件（需要Pro版支持），然后服务端爱咋整就咋整。
