Overview

This Discord bot, named "Core", was developed to enhance server management and user interaction. It provides a range of features including music playback, moderation tools, and fun commands that make Discord server management easier and more engaging.

Features

Music Player

Play music from YouTube directly in voice channels with commands for playback control and queue management.

Translation

Translate text between different languages using Google's translation API.

Moderation

Clear chat messages and manage server content with simple commands.

Fun Commands

Engage users with fun commands like coin toss and other interactive features.

Technology Stack

Python

Discord.py

YouTube-DL

Flask

Implementation

The bot is built using Discord.py, a powerful Python library for interacting with the Discord API. It uses a command handler system with the prefix '#' to organize and manage different commands.

@bot.command()
async def play(ctx,url):
  if ctx.author.voice is None:
    await ctx.send("Join a vc to use the bot.")

  elif len(url) == 0:
      return await ctx.send("You need to include a url")

  elif ctx.voice_client is None:
    voice_channel = ctx.author.voice.channel
    await voice_channel.connect()
    await ctx.send("Playing {}".format(url))
    if not ctx.message.author.voice:
      await ctx.send("You have to be connected to a voice channel")
      return
    else:
      channel = ctx.message.author.voice.channel

    ffmpeg_options = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    ydl_options = {'format': "bestaudio"}
    vc = ctx.voice_client

    with youtube_dl.YoutubeDL(ydl_options) as ydl:
      info = ydl.extract_info(url, download = False)
      url2 = info['formats'][0]['url']
      source = await discord.FFmpegOpusAudio.from_probe(url2, **ffmpeg_options)
    vc.play(source)

The bot includes a status cycling feature that alternates between different status messages, and uses Flask to create a simple web server to keep the bot alive when hosted on platforms like Replit.

status = itertools.cycle(['I am Core','Core'])

@bot.event
async def on_ready():
  change_status.start()
  print("Your bot is ready")

@tasks.loop(seconds=10)
async def change_status():
  await bot.change_presence(activity=discord.Game(next(status)))

Key Commands

Music Commands

#play [url] - Play music from a YouTube URL
#queue [song] - Add a song to the queue
#leave - Disconnect the bot from voice channel

Utility Commands

#tr [language] [text] - Translate text to specified language
#clear [amount] - Clear specified number of messages
#man - Display manual with all commands
#toss - Flip a coin

Challenges & Solutions

Music Streaming

Implementing reliable music streaming from YouTube required handling various edge cases like disconnections and format changes. I used FFmpeg with specific options to ensure reliable reconnection and optimal audio quality.

Bot Hosting

Keeping the bot running 24/7 was a challenge. I implemented a Flask web server with a keep-alive function to prevent the bot from going idle when hosted on platforms like Replit.

Future Enhancements

Spotify integration for expanded music options
Advanced moderation features like auto-moderation and warning systems
Custom server settings and configuration options
Integration with more external APIs for expanded functionality
