PHP, Unity3D and Workerman: How to implement a massively multiplayer online game

With the popularity of the Internet, multiplayer online games are becoming increasingly popular among players. For game developers, how to implement an efficient and stable massively multiplayer online game is a very important issue. This article will introduce how to combine PHP, Unity3D and Workerman to implement such a game.

1. Overview

Before we start discussing the specific implementation details, let’s first sort out the structure of the entire game. We will use PHP as the back-end server to handle game logic and data storage, Unity3D as the client to render the game interface and handle user operations, and Workerman as the multiplayer online game server to achieve real-time communication.

2. Back-end server (PHP)

1. Database design

In game development, the database is a very important part. We need to design a database structure suitable for the game and use PHP to operate the database. The following is a simple example of a player data table:

CREATE TABLE `player` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `level` int(11) NOT NULL DEFAULT '1',
  `exp` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. Game Logic

In PHP, we can use an object-oriented approach to implement game logic. The following is a simple example of player upgrade logic:

// Player.php
class Player {
  private $id;
  private $name;
  private $level;
  private $exp;

  public function __construct($id, $name, $level, $exp) {
    $this->id = $id;
    $this->name = $name;
    $this->level = $level;
    $this->exp = $exp;
  }

  public function levelUp($exp) {
    $this->exp += $exp;
    if ($this->exp >= 100) {
      $this->level++;
      $this->exp -= 100;
    }
  }

  // Getters and setters...
}

3. Database operation

In actual development, we need to write some PHP functions to handle database operations. The following is a simple example of querying player information:

function getPlayerById($id) {
  $conn = new mysqli('localhost', 'username', 'password', 'database');
  $sql = 'SELECT * FROM player WHERE id = ' . $id;
  $result = $conn->query($sql);
  if ($result->num_rows > 0) {
    $row = $result->fetch_assoc();
    return new Player($row['id'], $row['name'], $row['level'], $row['exp']);
  } else {
    return null;
  }
}

3. Client (Unity3D)

In Unity3D, we can use C# to write game logic and handle user operations. The following is an example of a simple player upgrade operation:

public class Player : MonoBehaviour {
  public int level = 1;
  public int exp = 0;

  public void LevelUp(int exp) {
    this.exp += exp;
    if (this.exp >= 100) {
      level++;
      this.exp -= 100;
    }
  }
  
  // Other methods...
  
  void Update() {
    // Handle user input and update game state...
  }
}

4. Multiplayer online server (Workerman)

Workerman is an open source high-performance socket server framework based on PHP that can be used Enable real-time communication. We can use Workerman to implement a multiplayer online game server and interact with the PHP backend server for data. The following is a simple Workerman server example:

use WorkermanWorker;
require_once '/path/to/Workerman/Autoloader.php';

$worker = new Worker('websocket://0.0.0.0:1234');
$worker->onConnect = function($connection) {
  // Handle new client connection...
};
$worker->onMessage = function($connection, $data) {
  // Handle client messages...
};
$worker->onClose = function($connection) {
  // Handle client disconnection...
};

Worker::runAll();

In the above example, we can define callback functions such as onConnect, onMessage and onClose as needed to handle client connection, message and disconnection events.

Summary

By combining PHP’s backend server, Unity3D’s client and Workerman’s multiplayer online server, we can achieve an efficient and stable large-scale multiplayer online game. During the development process, we need to reasonably design the database structure, write game logic, and use tools such as PHP, C#, and Workerman to implement the functions of each module. I hope this article helps you understand how to implement multiplayer online games.
