How to use Workerman to realize real-time competitive battle games through the combination of PHP and Unity3D

With the development of network technology, real-time competitive battle games are becoming more and more popular among players. PHP is a popular server-side scripting language, while Unity3D is a powerful game development engine. In this article, we will introduce how to use Workerman with PHP and Unity3D to implement a game based on real-time network battles.

1. Understanding Workerman

Workerman is a high-performance network communication engine written in pure PHP. It can realize multi-process or multi-thread asynchronous communication. Workerman can easily perform TCP/UDP communication and supports features such as long connections and event-driven. We will use Workerman to implement the real-time communication function of the game server.

2. Set up the server

First, we need to install Workerman on the server. We can use Composer to install and create a new Workerman application through the following command:

composer create-project workerman/workerman my_game_server
cd my_game_server

Then, we create a Server.php file in the project directory with the following code:

<?php
use WorkermanWorker;

require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker('websocket://0.0.0.0:8000');
$worker->count = 1;

$worker->onConnect = function($connection)
{
    // 处理新的连接
};

$worker->onMessage = function($connection, $data)
{
    // 处理收到的消息
};

$worker->onClose = function($connection)
{
    // 处理连接关闭
};

Worker::runAll();

This The code snippet creates a WebSocket server with listening port 8000. We can modify it according to our needs. In the onConnect, onMessage and onClose callback functions, we can write our own logic to handle connection, message and connection closing events.

3. Real-time communication

After setting up the server side, we need to realize communication with the server in Unity3D. First, we need to download and import the WebSocketSharp plugin. Then, we can create a C# script with the following code:

using UnityEngine;
using WebSocketSharp;

public class GameClient : MonoBehaviour
{
    private WebSocket webSocket;

    void Start()
    {
        webSocket = new WebSocket("ws://your_server_ip:8000");
        webSocket.OnOpen += OnOpen;
        webSocket.OnMessage += OnMessage;
        webSocket.OnClose += OnClose;
        webSocket.Connect();
    }

    private void OnOpen(object sender, System.EventArgs e)
    {
        // 连接成功
    }

    private void OnMessage(object sender, MessageEventArgs e)
    {
        // 处理收到的消息
    }

    private void OnClose(object sender, CloseEventArgs e)
    {
        // 连接关闭
    }

    void Update()
    {
        // 游戏逻辑更新
    }
}

In the Start function, we create a WebSocket object and specify the connected server address and port. We can then handle connection status, received messages, and connection closing events through the OnOpen, OnMessage, and OnClose events.

4. Implementing game logic

Game logic can be implemented by processing messages on both the server side and the client side. For example, when a new connection comes in, the server can assign a unique identifier to this connection and send it to the client. The client can save this identifier and use it in the game.

The server can provide logical judgment for real-time battles between players. For example, when two players play against each other, the server can detect the player's behavior and make a judgment, and then send the game results to the client for display.

Through the above implementation, we can use Workerman to implement a real-time competitive battle game through the combination of PHP and Unity3D. With the high-performance communication capabilities provided by Workerman, we can easily handle large numbers of player connections and messages. At the same time, the game development engine provided by Unity3D allows us to easily implement the logic and interface of the game. I hope this article is helpful to you, and I wish you a great game!
