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

Music games have always been loved by players. By operating the game through the rhythm of music, you can not only enjoy the wonderful Music can also stimulate players' enthusiasm for gaming. This article will introduce how to use three excellent development tools, PHP, Unity3D and Workerman, to create a new music game.

First of all, we need to build a back-end server and use PHP as the back-end language to process the game logic and data. The following is a simple PHP back-end code example for processing the data interface and logic in the game:

<?php
// 数据接口示例
function getSongList() {
    // 获取歌曲列表逻辑
    return [
        ['id' => 1, 'name' => 'Song1', 'url' => 'http://www.example.com/song1.mp3'],
        ['id' => 2, 'name' => 'Song2', 'url' => 'http://www.example.com/song2.mp3'],
        ['id' => 3, 'name' => 'Song3', 'url' => 'http://www.example.com/song3.mp3']
    ];
}

function saveScore($userId, $songId, $score) {
    // 保存分数逻辑
}

// 处理请求
$action = $_GET['action'];
switch ($action) {
    case 'getSongList':
        $data = getSongList();
        break;
    case 'saveScore':
        // 获取参数
        $userId = $_POST['userId'];
        $songId = $_POST['songId'];
        $score = $_POST['score'];
        saveScore($userId, $songId, $score);
        // 返回结果
        $data = ['status' => 'success'];
        break;
    default:
        $data = ['status' => 'error', 'message' => 'Invalid action'];
}

// 返回结果
header('Content-Type: application/json');
echo json_encode($data);
?>

In the above code example, we defined two data interfaces: getSongListUse Used to get the song list, saveScore is used to save the player's score. According to different request parameters (passed through GET or POST), we can execute the corresponding logic and return the results.

Next, we use Unity3D to develop the game front-end. Unity3D is a powerful game engine that can easily achieve rich visual effects and interactive experiences. We will create the scene and gameplay of the music game in Unity3D. The following is a simple Unity3D code example to implement the core logic of the game:

using UnityEngine;

public class MusicGameController : MonoBehaviour {
    // 游戏对象
    public AudioSource audioSource;
    public GameObject notePrefab;
    public Transform noteSpawnPoint;

    // 游戏参数
    public float notesPerSecond;

    // 游戏状态
    private bool isPlaying = false;

    private void Start() {
        // 开始游戏
        StartGame();
    }

    private void Update() {
        // 播放音乐
        if (isPlaying && !audioSource.isPlaying) {
            audioSource.Play();
        }

        // 生成音符
        if (isPlaying && Time.time % (1 / notesPerSecond) <= Time.deltaTime) {
            Instantiate(notePrefab, noteSpawnPoint.position, noteSpawnPoint.rotation);
        }
    }

    // 开始游戏
    private void StartGame() {
        // 加载音乐
        AudioClip music = Resources.Load<AudioClip>("Music/Song1");
        audioSource.clip = music;

        // 开始播放音乐
        isPlaying = true;
        audioSource.Play();
    }

    // 结束游戏
    private void EndGame() {
        // 停止播放音乐
        isPlaying = false;
        audioSource.Stop();
    }

    // 保存分数
    private void SaveScore(int userId, int songId, int score) {
        // 发送请求到后端服务器
        StartCoroutine(SaveScoreCoroutine(userId, songId, score));
    }

    private IEnumerator SaveScoreCoroutine(int userId, int songId, int score) {
        WWWForm form = new WWWForm();
        form.AddField("userId", userId);
        form.AddField("songId", songId);
        form.AddField("score", score);

        using (UnityWebRequest www = UnityWebRequest.Post("http://www.example.com/savescore.php", form)) {
            yield return www.SendWebRequest();

            if (www.result == UnityWebRequest.Result.Success) {
                Debug.Log("Score saved successfully!");
            } else {
                Debug.LogError(www.error);
            }
        }
    }
}

In the above code example, we created a MusicGameController script to control the behavior of the game. At the start of the game we load the music and start playing. Then, we generate the note on each frame update and create a note game object through the Instantiate method. Gamers can play the game by operating musical notes.

Finally, we use Workerman to build a WebSocket server to achieve real-time multiplayer game interaction. We can use Workerman's GatewayWorker extension to achieve this functionality. The following is a simple Workerman code example for implementing the logic of multiplayer game interaction:

use WorkermanWorker;
use GatewayWorkerGateway;

// 创建GatewayWorker服务器
$worker = new Worker();
$worker->count = 4;

// Gateway进程
$gateway = new Gateway("Websocket://0.0.0.0:1234");
$gateway->count = $worker->count;

// 进程启动时初始化游戏场景
$gateway->onConnect = function ($connection) {
    $userId = $_GET['userId'];
    $songId = $_GET['songId'];
    
    $data = [
        'action' => 'initGame',
        'userId' => $userId,
        'songId' => $songId
    ];

    // 发送初始化消息给客户端
    $connection->send(json_encode($data));
};

// 处理客户端发送的消息
$gateway->onMessage = function ($connection, $data) {
    // 处理游戏逻辑和数据
    $data = json_decode($data, true);
    // ...
};

// 启动服务器
Worker::runAll();

In the above code example, we use Workerman's GatewayWorker extension to create a WebSocket server and connect and message on the client Corresponding logical processing is performed when receiving. When the client connects, we send the game initialization message to the client. When the client sends a message, we can process the corresponding game logic and data.

To sum up, by using three excellent development tools, PHP, Unity3D and Workerman, we can realize a brand new music game. PHP serves as the back-end server to process game logic and data, Unity3D serves as the game front-end to achieve rich visual effects and interactive experience, and Workerman serves as the WebSocket server to achieve real-time multiplayer game interaction. I hope this article can inspire developers and help them create more creative and interesting game works.
