How to use PHP and Unity3D combined with Workerman to implement a game item trading system

Introduction:
With the popularity of online games, the game item trading system is becoming more and more important. In order to meet the needs of players, it is crucial to develop a stable and efficient item trading system. This article will introduce how to use PHP and Unity3D combined with Workerman to build a reliable game item trading system, and provide corresponding code examples.

1. Build a server
First, we need to build a server to handle item transaction requests between players. In this example, we will use Workerman as the server framework.
The following are key code examples for building a server:

// 引入Workerman库
require_once __DIR__ . '/workerman/Autoloader.php';

// 创建一个Workerman实例
$worker = new Worker('tcp://127.0.0.1:1234');

// 设置进程数
$worker->count = 4;

// 当有客户端连接时触发的回调函数
$worker->onConnect = function($connection){
    echo "New connection
";
};

// 当接收到客户端消息时触发的回调函数
$worker->onMessage = function($connection, $data){
    echo "Received message: " . $data . "
";
};

// 启动服务器
Worker::runAll();

2. Implement the item trading function
Next, we need to implement the item trading function on the server side, including item trading requests between players, Verify and confirm operations.
The following is a code example for server-side processing of item transactions:

// 当接收到客户端消息时触发的回调函数
$worker->onMessage = function($connection, $data){
    // 解析客户端发来的JSON数据
    $message = json_decode($data, true);

    // 获取玩家请求的操作类型
    $action = $message['action'];

    // 根据操作类型执行相应的逻辑
    switch($action){
        case 'request_trade':
            $result = handleTradeRequest($message);
            $connection->send(json_encode($result));
            break;
        case 'confirm_trade':
            $result = handleTradeConfirmation($message);
            $connection->send(json_encode($result));
            break;
        default:
            $connection->send(json_encode(['error' => 'Invalid action']));
            break;
    }
};

// 处理物品交易请求
function handleTradeRequest($message){
    // 根据客户端发来的数据进行物品交易请求的处理逻辑

    // 返回交易结果
    return ['result' => 'success'];
}

// 处理物品交易确认
function handleTradeConfirmation($message){
    // 根据客户端发来的数据进行物品交易确认的处理逻辑

    // 返回确认结果
    return ['result' => 'success'];
}

3. Sending and receiving transaction requests in Unity3D
Finally, we need to implement sending and receiving transaction requests in the Unity3D game client function.
The following is a code example for sending and receiving transaction requests in the Unity3D game client:

using UnityEngine;
using System.Collections;
using System.Net.Sockets;
using System.IO;
using System.Text;

public class TradeManager : MonoBehaviour {
    private TcpClient client;
    private NetworkStream stream;
    private StreamReader reader;
    private StreamWriter writer;

    void Start(){
        // 连接服务器
        ConnectToServer();
    }

    public void RequestTrade(string player, int itemId){
        // 构建交易请求消息
        string message = "{ "action": "request_trade", "player": "" + player + "", "item_id": " + itemId + " }";

        // 发送交易请求消息给服务器
        writer.WriteLine(message);
        writer.Flush();

        // 接收服务器返回的结果
        string response = reader.ReadLine();
        // 解析返回结果
        // ...
    }

    public void ConfirmTrade(string player, int itemId){
        // 构建交易确认消息
        string message = "{ "action": "confirm_trade", "player": "" + player + "", "item_id": " + itemId + " }";

        // 发送交易确认消息给服务器
        writer.WriteLine(message);
        writer.Flush();

        // 接收服务器返回的结果
        string response = reader.ReadLine();
        // 解析返回结果
        // ...
    }

    void ConnectToServer(){
        // 连接服务器
        client = new TcpClient("127.0.0.1", 1234);
        stream = client.GetStream();
        reader = new StreamReader(stream, Encoding.UTF8);
        writer = new StreamWriter(stream, Encoding.UTF8);
    }
}

Conclusion:
Through the above example code, we successfully used PHP and Unity3D combined with Workerman to implement a simple Game item trading system. In actual development, you can expand and optimize according to your own needs. I hope this article can help you build a game item trading system.
