How PHP and Unity3D use Workerman to implement the skills and magic system in the game

Introduction:
With the continuous development of the game industry, the skill and magic system plays an important role in the game. The implementation of skills and magic systems needs to take into account the real-time and concurrency of the game, and the combination of PHP and Unity3D combined with Workerman can well meet these needs. This article will introduce how to use the Workerman framework to implement the skills and magic system in the game, and provide corresponding code examples.

1. Introduction to Workerman
Workerman is an open source PHP asynchronous Socket server framework that supports high-concurrency and high-performance network application writing. It provides some high-performance components for building real-time network applications, including Tcp connection management, asynchronous communication, etc.

2. Design Ideas for Skills and Magic Systems
In the game, skills and magic systems are important components for player interaction. The following is the design idea of ​​the skill and magic system:

1. Definition of skills and magic:

   • Skills: specific abilities that players can use, such as attack skills, Defense skills, etc.
   • Magic: Specific magic that players can use, such as fireball, healing, etc.

2. Conditions for triggering skills and magic:

   • The player presses specific keys or performs specific operations.
   • Specific events occur, such as being attacked, enemy death, etc.

3. The effects of skills and magic:

   • The effect on the enemy or one's own attributes.
   • Send messages to other players.

3. Use Workerman to implement skills and magic systems
The following takes a simple attack skill as an example to introduce how to use Workerman to implement skills and magic systems.

1. Server-side code:

require_once __DIR__ . '/Workerman/Autoloader.php'; // 引入Workerman的自动加载文件

use WorkermanWorker;

// 创建一个Worker监听8899端口
$worker = new Worker('tcp://0.0.0.0:8899');

// 当接收到客户端的数据时触发的回调函数
$worker->onMessage = function($connection, $data) {
    // 解析客户端传来的数据，如当前位置、技能ID等
    $playerId = $data['playerId'];
    $skillId = $data['skillId'];
    $positionX = $data['positionX'];
    $positionY = $data['positionY'];

    // 处理技能逻辑，如判断是否命中、伤害计算等
    // ...

    // 将技能结果发送给其他玩家
    $connection->send('Player' . $playerId . '使用技能' . $skillId . '，造成XX伤害');

};

// 运行Worker
Worker::runAll();

2. Client-side code (Unity3D):

using UnityEngine;
using System.Collections;
using System.Net.Sockets;
using System.Text;

public class GameController : MonoBehaviour {

    TcpClient tcpClient;

    void Start() {
        tcpClient = new TcpClient();
        tcpClient.Connect("127.0.0.1", 8899); // 连接服务器

        // 模拟技能触发
        StartCoroutine(AttackSkill());
    }

    IEnumerator AttackSkill() {
        // 等待技能触发时机
        yield return new WaitForSeconds(1);

        // 构造技能数据
        int playerId = 1;
        int skillId = 100;
        float positionX = transform.position.x;
        float positionY = transform.position.y;

        // 将技能数据转换为字符串发送给服务器
        string data = JsonUtility.ToJson(new { playerId, skillId, positionX, positionY });
        tcpClient.GetStream().Write(Encoding.ASCII.GetBytes(data), 0, data.Length);
    }
}

IV. Summary
This article It introduces how to use the Workerman framework to implement the skills and magic system in the game, and provides code examples for the PHP server and Unity3D client. Through Workerman's high-performance and asynchronous communication mechanism, we are able to achieve real-time network communication, allowing players to happily use various skills and magic in the game.

By studying this article, readers can further expand the functions of the skill and magic system, such as adding more skill types, special effects, etc., to provide a better gaming experience. At the same time, similar ideas and tools can also be used to implement functions in other games, such as chat systems, task systems, etc.
