Integrated application of PHP, Unity3D and Workerman: How to create a virtual reality experience

Virtual Reality (Virtual Reality, referred to as VR) is a kind of simulation of real situations through computer technology, perception technology and artificial intelligence technology Technology systems that provide an immersive experience. With the continuous development of VR technology, more and more people are becoming interested in virtual reality experience. This article will introduce how to use PHP, Unity3D and Workerman to combine three technologies to create a virtual reality experience.

First of all, we need to understand the basic concepts and functions of the three technologies.

PHP is a scripting language mainly used for developing web applications. It is easy to learn, runs fast, and has a short development cycle. It is very suitable for developing server-side functions. In the virtual reality experience, we can use PHP to build a web server to provide data interaction and information transmission functions.

Unity3D is a cross-platform game engine that is widely used in the field of game development. It provides a wealth of development tools and resources, which can realize functions such as the layout of virtual reality scenes, the construction of object models, and the realization of animations. In the virtual reality experience, we can use Unity3D to build virtual reality scenes and achieve real-time data transmission and interaction through interaction with the server.

Workerman is a high-performance PHP Socket server framework, mainly used for developing long-connection applications. It uses multi-process, Event-driven and other technologies to achieve high concurrent processing capabilities of the server, and is suitable for real-time communication and data transmission scenarios. In the virtual reality experience, we can use Workerman as the server framework to achieve real-time communication and data transmission with the Unity3D client.

Next, we will use an example to demonstrate how to use these three technologies to create a virtual reality experience. Suppose we want to build a multiplayer competitive game scene. Players can enter the virtual scene by wearing VR equipment and compete with other players in real time.

First, we need to build a PHP server to handle player connection requests and real-time data transmission. We can use the Workerman framework to achieve:

<?php
use WorkermanWorker;

require_once __DIR__ . '/Workerman/Autoloader.php';

$ws_worker = new Worker("websocket://0.0.0.0:2345");

$ws_worker->count = 4;

$ws_worker->onMessage = function ($connection, $data) {
    global $ws_worker;
    foreach ($ws_worker->connections as $client_connection) {
        $client_connection->send($data);
    }
};

Worker::runAll();
?>

In Unity3D, we can create a virtual reality scene and add corresponding characters and game elements. At the same time, we also need to add a network connection component to communicate with the server. The following is a simple Unity3D code example:

using UnityEngine;
using System.Collections;
using WebSocketSharp;

public class VRGame : MonoBehaviour
{
    private WebSocket ws;

    void Start()
    {
        ws = new WebSocket("ws://127.0.0.1:2345");
        ws.Connect();

        ws.OnMessage += (sender, e) =>
        {
            // 接收到服务器的消息后的处理逻辑
        };
    }

    void Update()
    {
        // 每一帧的处理逻辑
    }

    void OnApplicationQuit()
    {
        ws.Close();
    }
}

In the above code example, we create a WebSocket connection in Unity3D's Start function and trigger the corresponding processing logic when receiving a server message. In the Update function, we can write the game logic for each frame. Finally, when the application exits, we need to close the WebSocket connection.

Through the above examples, we can see that through the comprehensive application of PHP, Unity3D and Workerman, we can create a multiplayer competitive game scene with a virtual reality experience. In this scene, players can enter the virtual world through VR equipment and compete with other players in real time.

In summary, the development of virtual reality technology provides us with a new way of experience and interaction. By using PHP to build servers, Unity3D to create virtual scenes and characters, and Workerman to achieve real-time communication, we can create a more immersive and realistic virtual reality experience. At the same time, we can also extend this example and add more functions and scalability to meet the needs of different scenarios.
