Workerman Development: Implementing online games based on WebSocket protocol

Introduction:

Online games have always been one of the popular applications in the Internet field. Online games based on the WebSocket protocol have the characteristics of strong real-time performance and two-way communication, so they are loved by the majority of players. This article will introduce how to use the Workerman framework to develop online games based on the WebSocket protocol, and provide specific code examples to help readers quickly understand and practice.

1. Introduction of Workerman

Workerman is a high-performance, fully asynchronous event-driven framework based on PHP, mainly used for developing high-performance network applications. With its excellent performance and flexible design, we can develop online games based on the WebSocket protocol more efficiently.

2. Implementing a game server

The following code example shows how to use Workerman to implement a simple online game server.

<?php
require_once 'vendor/autoload.php';

use WorkermanWorker;

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

$ws_worker->onConnect = function ($connection) {
    echo "New connection: " . $connection->id . "
";
};

$ws_worker->onMessage = function ($connection, $data) {
    echo "Received message: " . $data . "
";
    $connection->send('Server received: ' . $data);
};

$ws_worker->onClose = function ($connection) {
    echo "Connection closed: " . $connection->id . "
";
};

Worker::runAll();

Copy after login

The above code creates a WebSocket server and handles client connection, message reception and connection closing events. Whenever a client connects, the onConnect event is triggered. When a message from the client is received, the onMessage event is triggered. When the connection is closed, onClose event is triggered.

3. Implement client interaction

Next, we need to implement a client based on the WebSocket protocol to interact with the server. The following code example shows how to use JavaScript to implement a simple client that communicates with the server mentioned above.

<!DOCTYPE html>
<html>
<head>
    <title>WebSocket Demo</title>
</head>
<body>
    <script type="text/javascript">
        var socket = new WebSocket("ws://localhost:8080");

        socket.onopen = function () {
            console.log("Connected to server.");
            socket.send("Hello server!");
        };

        socket.onmessage = function (e) {
            console.log("Server says: " + e.data);
        };

        socket.onclose = function () {
            console.log("Connection closed.");
        };
    </script>
</body>
</html>

Copy after login

The above code realizes connection and message interaction with the server by creating a WebSocket object and specifying the address and port of the server. When the connection is successful, the onopen event is triggered, in which we can send a message to the server; when a message returned from the server is received, the onmessage event is triggered, in which we can process Data sent from the server; when the connection is closed, the onclose event is triggered.

Conclusion:

Through the introduction and code examples of this article, we have learned how to use the Workerman framework to develop online games based on the WebSocket protocol. This is just a simple example. Actual game development may involve more game logic and interactions, and readers can expand and optimize according to their own needs. Using the Workerman framework, we can easily implement high-performance, real-time online games to bring players a better gaming experience.
