服务器和客户端是连接起来了，我们看看如何让同步服务器、客户端上物体的坐标。

前一篇减少的服务器、客户端程序是写在两个不同的 Scene 中的，但要让物体同步坐标，则需要把服务器、客户端程序放到一个 Scene 中。（额，至少目前研究看来，必须如此）

可以理解为，服务器、客户端通过网络，只同步坐标数据，并不会把物体本身的信息发送过去。所以要求服务器、客户端一开始都有这个物体。

先创建服务器连接的代码：

-------------------------------------------------------------------------------------

var ServerAddr : String = "127.0.0.1";
var ServerPort : int = 2224;

function OnGUI()
{
 if (Network.peerType == NetworkPeerType.Disconnected)
 {
  GUILayout.Label("Connection status: Disconnected");

  ServerAddr = GUILayout.TextField(ServerAddr, GUILayout.MinWidth(100));
  ServerPort = parseInt(GUILayout.TextField(ServerPort.ToString()));

  if (GUILayout.Button("Connect as client"))
  {
   Network.Connect(ServerAddr, ServerPort);
  }

  if (GUILayout.Button("Start Server"))
  {
   Network.InitializeServer(32, ServerPort, 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("Print to firty player: " + Network.GetAveragePing(Network.connections[0]));
   }
  }
  else if (Network.peerType == NetworkPeerType.Connecting)
  {
   GUILayout.Label("Connetion 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);
  }
 }
}

-------------------------------------------------------------------------------------

在场景中创建个 Cube。

再弄个物体移动的代码（要把这个 Script文件拖到 Cube 对象上）：

-------------------------------------------------------------------------------------

function Update ()
{
 if (Network.isServer)
 {
  var moveDirection : Vector3 = new Vector3(0, 0, -1);
  var speed : float = 10;
  transform.Translate(speed * moveDirection * Time.deltaTime);
 }
}
-------------------------------------------------------------------------------------

最后创建一个 NetworkView：

1. 选择 Cube

2. 从菜单选择 Component => Miscellaneous => NetworkView，给此 GameObject 增加一个 NetworkView

ok. 运行服务器/客户端，可以同时看到 Cube 在移动了。
