PHP, Unity3D and Workerman: How to build a multi-platform game development framework

Introduction:
With the rapid popularity of mobile devices, game development has become more and more important. Game development on different platforms has also become a challenge. This article will introduce how to use PHP, Unity3D and Workerman to create a multi-platform game development framework to help developers develop games more efficiently.

1. Why choose PHP, Unity3D and Workerman?
When choosing a development framework, the first thing to consider is cross-platform support and performance. PHP has good cross-platform features and is excellent in network programming. Unity3D is a cross-platform game engine that supports multiple mobile device platforms. Workerman is a high-performance PHP Socket server framework suitable for handling high concurrent network connections. Combining these three technologies, we can implement a multi-platform game development framework.

2. Build the server
First, we need to build a PHP server to handle client requests and game logic. We can use Workerman as the server framework and build the server through the following code:

<?php
require_once './Workerman/Autoloader.php';

use WorkermanWorker;

$worker = new Worker("websocket://0.0.0.0:8000");

$worker->onMessage = function($connection, $data){
    // 处理客户端发送的消息
    processMessage($connection, $data);
};

function processMessage($connection, $data){
    // 处理消息逻辑
    // ...
}

Worker::runAll();

This code creates a server based on the WebSocket protocol and listens for client connections on port 8000. When the client sends a message, the server calls the processMessage function for message processing.

3. Writing the Unity3D game client
To write the game client in Unity3D, we need to use the C# language. The following is a simple Unity3D client code example:

using UnityEngine;
using System.Collections;
using WebSocketSharp;

public class GameClient : MonoBehaviour
{
    private WebSocket ws;

    void Start ()
    {
        ws = new WebSocket("ws://localhost:8000");
        ws.OnMessage += (sender, e) => {
            // 处理服务器发送的消息
            ProcessMessage(e.Data);
        };
        ws.Connect();
    }

    void ProcessMessage(string data)
    {
        // 处理消息逻辑
        // ...
    }

    void SendMessage(string message)
    {
        ws.Send(message);
    }
}

This code creates a WebSocket object and connects it to the server's address and port. When receiving a message sent by the server, the client will call the ProcessMessage function for processing.

4. Implement game logic
On the server side, we can implement game logic, such as interaction between players, data synchronization, etc. The following is a simple server-side game logic example:

function processMessage($connection, $data){
    // 解析客户端发送的消息
    $message = json_decode($data, true);

    // 根据消息类型执行相应的逻辑
    switch ($message['type']){
        case 'login':
            // 处理登录逻辑
            handleLogin($connection, $message['data']);
            break;
        case 'move':
            // 处理移动逻辑
            handleMove($connection, $message['data']);
            break;
        // ...
    }
}

// 登录逻辑
function handleLogin($connection, $data){
    // 处理登录逻辑
    // ...
    // 向客户端发送登录成功消息
    $response = [
        'type' => 'login',
        'data' => ['success' => true]
    ];
    $connection->send(json_encode($response));
}

This code parses the message sent by the client and executes the corresponding logic based on the message type. For example, when receiving a login message, the server will call the handleLogin function to process the login logic and send a login success message to the client.

5. Add network synchronization function
In game development, it is often necessary to synchronize data between players. We can use WebSocket to achieve simple data synchronization. The following is a simple data synchronization example:

void Update()
{
    // 获取玩家位置等数据
    Vector3 position = transform.position;
    Quaternion rotation = transform.rotation;

    // 构建同步数据
    var syncData = new
    {
        type = "sync",
        data = new
        {
            position = new { x = position.x, y = position.y, z = position.z },
            rotation = new { x = rotation.x, y = rotation.y, z = rotation.z, w = rotation.w }
        }
    };

    // 向服务器发送同步数据
    SendMessage(JsonUtility.ToJson(syncData));
}

This code obtains the player's position and rotation data and builds synchronized data when each frame is updated. Then, send the sync data to the server.

The above is a brief introduction to using PHP, Unity3D and Workerman to create a multi-platform game development framework. Through this framework, we can quickly develop multi-platform games and achieve data synchronization between the server and the client. I hope this framework will be helpful to game developers!
