客户端是 C#，就简单先以和服务器端连接，发送，接收做例子，进一步就是方块移动，坐标传递。

1. 简单通讯

客户端只是用面板画出一个输入框 (地址) 和显示区域 (接收服务端发送的内容)，而服务器端是创建 TCP 服务，接收与发送。

(1). 客户端连接

1

//连接 public void Connetion() { //清理text recvText.text = ""; //Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); //Connect string host = hostInput.text; int port = int.Parse(portInput.text); socket.Connect(host, port); clientText.text = "客户端地址1 " + socket.LocalEndPoint.ToString(); //Recv socket.BeginReceive(readBuff, 0, BUFFER_SIZE, SocketFlags.None, ReceiveCb, null); }

(2). 客户端接收

2

//接收回调 private void ReceiveCb(IAsyncResult ar) { try { //count是接收数据的大小 int count = socket.EndReceive(ar); //数据处理 string str = System.Text.Encoding.UTF8.GetString(readBuff, 0, count); if (recvStr.Length > 300) recvStr = ""; recvStr += str + "\n"; recvText.text = "接收的消息 " + recvStr; Debug.LogError("接收的消息 "+ recvStr); //继续接收 socket.BeginReceive(readBuff, 0, BUFFER_SIZE, SocketFlags.None, ReceiveCb, null); } catch (Exception e) { recvText.text += "链接已断开"; socket.Close(); } }

(3). 客户端发送

3	//发送数据 public void Send() { string str = textInput.text; byte[] bytes = System.Text.Encoding.Default.GetBytes("test:" + str); try { socket.Send(bytes); } catch { } }

2. workerman 安装

(1). 新启一个项目，进入该目录，composer require workerman/workerman

(2). 创建一个 start.php

4

<?phpuse Workerman\Worker;require_once __DIR__ . '/vendor/autoload.php';// #### 开启TCP服务 ####$worker = new Worker('tcp://0.0.0.0:1234');// 4 processes//$worker->count = 4;// 客户端连接回调$worker->onConnect = function ($connection) { echo "New Connection\n";};// 接收客户端消息$worker->onMessage = function ($connection, $data) use ($worker) { // Send data to client echo json_encode($data) . "\n"; //$ip = $connection->getRemoteIp(); foreach($worker->connections as $connection) { $connection->send($data); } //$connection->send("Hello $data \n");};// 客户端关闭回调$worker->onClose = function ($connection) { echo "Connection closed\n";};Worker::runAll();?>

(3). 启动，输入 php start.php start，成功如下

(4). 打开客户端的 6asyn 场景并运行，输入 TCP 服务的地址和端口

(5). 点击发送，就可以查看 workerman 接收到的信息。

3. 方块移动案例

方块移动服务器端几乎不用修改，在连接成功后，将多个客户端的坐标传递到服务器端，服务器处理后再给所有连接发送坐标，客户端再将数据绘制到场景中。

(1). 前后端数据约定

POS 用于标识行为，比如 POS 为坐标移动，同理聊天可以用 IM，登陆用 LOGIN 做标识等 (攻击)。第二个为客户端连接标识，标识往后为坐标 X, Y, Z。

(2). 坐标的整合发送

服务器端在接收消息回调中，循环所有连接端，并给所有连接端发送从客户端发送过来的坐标。

5	$worker->onMessage = function ($connection, $data) use ($worker) { // 循环连接 foreach($worker->connections as $connection) { // 发送坐标 $connection->send($data); }};

客户端维护一个名为 players 的字典，它将存放所有玩家的信息。msgList 是消息列表，接收到服务端的消息后，客户端会将消息保存在 msgList 中，等待 Update 逐一进行处理。
