Integrated application of PHP, Unity3D and Workerman: How to create a new simulated city game

With the development of technology and the popularity of the Internet, games have become an indispensable part of people's lives. As one of the classic genres, SimCity games have always been loved by many players. This article will introduce how to use the comprehensive application of PHP, Unity3D and Workerman to create a new simulated city game.

1. Environment preparation

Before we start, we need to prepare the following environment:

• A server capable of running PHP
• Installed Unity3D development environment
• Workerman’s PHP framework

2. Backend development

First, we need to use the Workerman framework to build A PHP backend server used to handle game logic and data interaction. The following is a simple example:

//引入Workerman
require_once('Workerman/Autoloader.php');

//创建一个Worker监听9000端口
$worker = new Worker('websocket://0.0.0.0:9000');

//设置进程数
$worker->count = 4;

//当客户端连接时
$worker->onConnect = function($connection) {
    echo "New connection
";
};

//当客户端发送消息时
$worker->onMessage = function($connection, $data) {
    global $worker;
    //处理消息逻辑
    $response = handle_message($data);
    //将处理结果返回给客户端
    $connection->send($response);
};

//当客户端断开连接时
$worker->onClose = function($connection) {
    echo "Connection closed
";
};

//运行worker
Worker::runAll();

In the above example, we created a Worker that listens to port 9000. When the client connects, sends a message, or disconnects, the corresponding event callback function is triggered. In the onMessage callback function, we can perform logical processing based on the received message and return the processing results to the client.

3. Client development

Next, we need to use Unity3D for client development. In Unity3D, we can use C# for development. The following is a simple example:

using UnityEngine;
using System.Collections;
using System.Net.WebSockets;

public class GameManager : MonoBehaviour
{
    private ClientWebSocket websocket;

    // 连接服务器
    public async void ConnectServer()
    {
        websocket = new ClientWebSocket();
        await websocket.ConnectAsync(new Uri("ws://localhost:9000"), CancellationToken.None);

        StartCoroutine(ReceiveMessage());
    }

    // 发送消息
    public async void SendMessage(string message)
    {
        byte[] bytes = Encoding.UTF8.GetBytes(message);
        await websocket.SendAsync(new ArraySegment<byte>(bytes), WebSocketMessageType.Text, true, CancellationToken.None);
    }

    // 接收消息
    private IEnumerator ReceiveMessage()
    {
        WebSocketReceiveResult result;
        byte[] buffer = new byte[1024];

        while (websocket.State == WebSocketState.Open)
        {
            result = await websocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);
            string message = Encoding.UTF8.GetString(buffer, 0, result.Count);

            // 处理接收到的消息
            HandleMessage(message);
        }
    }

    // 处理消息
    private void HandleMessage(string message)
    {
        // 处理服务器返回的消息逻辑
    }
}

In the above example, we use C#'s WebSocket class library to connect to the server and implement the function of sending and receiving messages. By calling the ConnectServer method, you can establish a connection with the server; by calling the SendMessage method, you can send messages to the server; by calling the HandleMessage method, you can process the reception from the server News arrived.

4. Game logic development

After the client and backend are built, we can start developing the game logic. According to the characteristics of the simulated city game, we can set some rules and goals, such as: building and managing the city, meeting the needs of citizens, developing the economy, etc. Send messages to the background by calling the client's method, and then the background performs logical processing and returns the results to complete the game interaction.

In game logic development, we can define a set of communication protocols between the client and the backend based on specific needs and design. For example, the client sends a message to build a new building, and the background performs corresponding processing and returns the result to the client. By agreeing on the format and commands of good messages, the communication between the client and the backend can be kept smooth.

To sum up, this article introduces the process of using the comprehensive application of PHP, Unity3D and Workerman to create a new simulated city game. By building a backend server and developing a client, as well as formulating the rules and goals of the game, interaction and communication between the game and players can be achieved.
