How to use Workerman with PHP and Unity3D to implement multiplayer online competitive games

Introduction:
With the rapid development of the Internet, multiplayer online competitive games are becoming more and more popular. In order to realize multiplayer online competitive games, we can use the cooperation of PHP and Unity3D, and then use Workerman, a high-performance PHP communication framework, to achieve this goal. This article demonstrates how to use these tools to create a web-based multiplayer game.

1. Preparation work
Before we start, we need to prepare the following resources:

1. PHP environment: Ensure that the version of PHP is not lower than 5.4, and install the necessary Extension.
2. Unity3D engine: Make sure the version is not lower than 5.0, create a new project.
3. Workerman: Install Workerman through composer.

2. Create the server side

1. Create a new PHP file on the server side and name it server.php.

2. Introduce Workerman's Autoloader and create a new Worker instance:

   <?php
   require_once 'vendor/autoload.php';
   use WorkermanWorker;
   
   $worker = new Worker('websocket://0.0.0.0:8000');

   Copy after login

3. Set the Worker's running parameters:

   $worker->count = 4;                       // 进程数
   $worker->name = 'MyGameServer';    // 服务器名称

   Copy after login

4. When a new client establishes a WebSocket connection, perform corresponding processing:

   $worker->onConnect = function($connection)
   {
    // 进一步处理连接逻辑
   };

   Copy after login

5. When receiving a message sent by the client, perform corresponding processing:

   $worker->onMessage = function($connection, $data)
   {
    // 进一步处理消息逻辑
   };

   Copy after login

   In this way, we have completed the creation of the server side.

3. Create the client

1. Create a new scene in the Unity3D engine and add an empty object as the container of the main script.

2. Use C# script to write the main logic:

   using UnityEngine;
   using System.Collections;
   using WebSocketSharp;
   
   public class GameClient : MonoBehaviour
   {
    private WebSocket ws;
   
    void Start()
    {
        // 连接服务器
        ws = new WebSocket("ws://your_server_ip:8000");
        ws.OnOpen += OnOpenHandler;
        ws.OnMessage += OnMessageHandler;
        ws.OnClose += OnCloseHandler;
        ws.Connect();
    }
   
    private void OnOpenHandler(object sender, System.EventArgs e)
    {
        // 进一步处理连接逻辑
    }
   
    private void OnMessageHandler(object sender, MessageEventArgs e)
    {
        // 进一步处理消息逻辑
    }
   
    private void OnCloseHandler(object sender, CloseEventArgs e)
    {
        // 处理关闭逻辑
    }
   }

   Copy after login
3. Mount the script to the main script container object and save the scene.

4. Implement multiplayer game logic

1. In the onConnect callback function on the server side, you can perform processing logic for players to join the game, such as generating new players. Character object and add it to the game.

   $worker->onConnect = function($connection)
   {
    // 创建新玩家对象
    $player = new Player();
    // 将新玩家对象加入游戏中
    Game::addPlayer($player);
    // 将玩家对象与连接绑定
    $connection->player = $player;
   };

   Copy after login

2. In the onMessage callback function on the server side, game logic can be processed, such as player movement, operations, etc.

   $worker->onMessage = function($connection, $data)
   {
    $player = $connection->player;
    // 处理玩家操作逻辑
    $player->handleOperation($data);
    // 向其他玩家广播操作信息
    Game::broadcastOperation($player, $data);
   };

   Copy after login

3. In the OnMessageHandler callback function of the Unity3D client, game logic can be processed, such as updating status, synchronizing the operations of other players, etc.

   private void OnMessageHandler(object sender, MessageEventArgs e)
   {
    // 处理服务器发送的游戏状态信息
    Game.Instance.UpdateState(e.Data);
   }

   Copy after login

4. In the main logic of the Unity3D client, the player operation is sent, in the OnOpenHandler callback function:

   private void OnOpenHandler(object sender, System.EventArgs e)
   {
    // 发送玩家准备开始游戏的消息
    ws.Send("ready");
   }

   Copy after login

   So far, we have successfully implemented the PHP-based and Unity3D’s multiplayer online competitive game.

Summary:
By using Workerman with PHP and Unity3D, we can realize multiplayer online competitive games. Using Workerman as a server-side framework, we can handle client connections and process messages. In the Unity3D client, we can use WebSocket to connect to the server and send and process in-game operations. The above steps are a general structure, and the specific game logic and function implementation need to be further developed and optimized based on actual needs.
