How to use Workerman to implement a real-time strategy confrontation game with PHP and Unity3D

Introduction:
Real-time strategy confrontation games have always been a hot topic in the field of game development. A good real-time strategy confrontation game can bring players A more challenging and interactive gaming experience. This article will introduce how to use the Workerman framework to implement a real-time strategic confrontation game between PHP and Unity3D. In this way, we can implement game logic processing on the Web side and display exquisite game graphics in Unity3D.

1. Overview
Workerman is a high-performance asynchronous event-driven framework based on PHP, which can realize high-concurrency and real-time communication applications. Unity3D is a powerful game development engine. Through the combination of Workerman and Unity3D, we can realize real-time game data communication and logic processing on the Web side, and display game scenes through Unity3D. Let’s take a simple real-time confrontation game as an example to introduce the specific implementation method.

2. Implementation process

1. Server-side implementation
Since this article focuses on the communication between Web and Unity3D, only the core code of the server side is shown here. First, we need to introduce the Workerman framework and create a Workerman instance:

require_once __DIR__ . '/workerman/Autoloader.php';
use WorkermanWorker;

$worker = new Worker('websocket://0.0.0.0:8080');

Next, we need to implement the callback function when a new connection is established. The code is as follows:

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

In this callback function, we can handle connection requests, such as adding newly connected clients to the game room. Then, we need to implement the callback function when data is received. The code is as follows:

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

In this callback function, we can specifically process the received data, such as updating player coordinates and sending game logic. wait. Finally, we need to implement the callback function when the connection is disconnected. The code is as follows:

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

In this callback function, we can handle the logic of disconnection, such as removing the disconnected client from the game removed from the room. Finally, we only need to run the Worker instance, the code is as follows:

Worker::runAll();

At this point, the server-side implementation has been completed.

2.Unity3D client implementation
In the Unity3D client, we need to first use WebSocket to establish a connection with the server. Using the WebSocket library that comes with Unity3D, we can easily implement this function. For how to use the WebSocket library, please check the official documentation of Unity3D.

After the connection is successful, we need to send game data to the server regularly. The code is as follows:

public class GameClient : MonoBehaviour {
    WebSocket webSocket;
    
    void Start() {
        // 连接服务器
        webSocket = new WebSocket("ws://localhost:8080");
        webSocket.Connect();
        
        // 开启定时器发送游戏数据
        InvokeRepeating("SendGameInfo", 0, 0.2f); //每隔0.2s发送一次游戏数据
    }
    
    void SendGameInfo() {
        // 发送游戏数据给服务器
        webSocket.Send("game info");
    }
    
    void OnDestroy() {
        // 断开与服务器的连接
        webSocket.Close();
    }
}

In this example, we simply send game data to the server every 0.2 seconds. . As for the specific content of game data, it is defined according to the actual situation.

3. Summary:
Realizing the real-time strategic confrontation game between PHP and Unity3D through the Workerman framework allows us to realize real-time communication and logical processing of game data on the Web side, and display exquisite game graphics through Unity3D. Workerman's high-performance and asynchronous event-driven features, as well as Unity3D's powerful game development engine, provide us with great convenience in developing real-time confrontation games. I hope this article can help readers who are interested in real-time strategy confrontation game development.
