Build a Multiplayer Game with Python and WebSockets

أصبحت روبوتات الدردشة (Chatbots) جزءًا أساسيًا من العديد من التطبيقات والمواقع الإلكترونية اليوم، حيث تقدم الدعم للمستخدمين وتوفر تجربة تفاعلية على مدار الساعة. في هذا الدليل، سنتعلم كيفية بناء روبوت دردشة بسيط باللغة العربية باستخدام Python وتقنيات معالجة اللغة الطبيعية (NLP).

• تقديم الدعم الذكي: توفير ردود فورية للمستخدمين.
• تجربة ممتعة: خلق تجربة تفاعلية تجعل المستخدمين يشعرون بالارتباط.
• توفير التكاليف: يقلل الحاجة للدعم البشري الدائم.

• Frameworks like Electron allow creating cross-platform desktop apps.
• Example: Visual Studio Code.

• JavaScript is used in IoT devices for controlling hardware and sensors.
• Example: Node.js-based IoT applications.

import asyncio

async def task(name, duration):
    print(f"Task {name} started.")
    await asyncio.sleep(duration)
    print(f"Task {name} finished after {duration} seconds.")

async def main():
    await asyncio.gather(
        task("A", 2),
        task("B", 1),
        task("C", 3),
    )

asyncio.run(main())
# Output: Tasks A, B, and C execute concurrently.

Coroutines can mimic generator pipelines, but they work asynchronously:

import datetime
import pywhatkit

def process_command(command):
    if "time" in command:
        now = datetime.datetime.now().strftime("%H:%M")
        speak(f"The time is {now}")
    elif "search for" in command:
        query = command.replace("search for", "").strip()
        speak(f"Searching for {query}")
        pywhatkit.search(query)
    elif "play" in command:
        song = command.replace("play", "").strip()
        speak(f"Playing {song}")
        pywhatkit.playonyt(song)
    else:
        speak("I'm sorry, I can't perform that task yet.")

Integrate a weather API (e.g., OpenWeatherMap) to fetch current weather information.

import schedule
import time

# Schedule the price checker to run every hour
schedule.every(1).hour.do(check_price)

while True:
    schedule.run_pending()
    time.sleep(1)

Run the script, and it will automatically check the product price every hour and send email alerts if the price drops below your threshold.

A virtual environment is an isolated environment that allows you to run and manage Python projects with their own dependencies. This isolation prevents conflicts between packages and versions, making it easier to manage multiple projects on the same machine.

Virtual environments help maintain a clean and organized development environment by:

     public class PlayerController : NetworkBehaviour
     {
         public GameObject bulletPrefab;
         public Transform bulletSpawn;

         void Update()
         {
             if (!IsOwner) return;

             // Movement code...

             if (Input.GetButtonDown("Fire1"))
             {
                 ShootServerRpc();
             }
         }

         [ServerRpc]
         void ShootServerRpc()
         {
             GameObject bullet = Instantiate(bulletPrefab, bulletSpawn.position, bulletSpawn.rotation);
             bullet.GetComponent<NetworkObject>().Spawn();
         }
     }

In this example, when the player presses the fire button, a ServerRpc is called to spawn a bullet on the server, which is then synchronized with all clients.

using UnityEngine;
using UnityEngine.UI;

public class InventoryUI : MonoBehaviour
{
    public Inventory inventory;
    public GameObject inventoryPanel;
    public GameObject inventorySlotPrefab;

    void Start()
    {
        RefreshInventoryUI();
    }

    public void RefreshInventoryUI()
    {
        // Clear existing UI elements
        foreach (Transform child in inventoryPanel.transform)
        {
            Destroy(child.gameObject);
        }

        // Create new UI elements
        foreach (Item item in inventory.items)
        {
            GameObject slot = Instantiate(inventorySlotPrefab, inventoryPanel.transform);
            Image iconImage = slot.transform.GetChild(0).GetComponent<Image>();
            iconImage.sprite = item.icon;

            // Add more UI logic as needed (like item count for stackable items)
        }
    }
}

• Data Management: Scriptable objects allow you to manage item data independently from game logic, making it easier to update and maintain.
• Reusability: You can create item templates and reuse them across different scenes and projects.
• Performance: Scriptable objects reduce memory overhead compared to prefab-based systems since they are shared across instances.
