Discord Bot Tutorial#3Adding Subcommands to Slash Commands!

Hi there! It's Mojangcam 😎 This time, we're stepping up to a more advanced feature! Let's look at subcommands, which group slash commands together!

For example...

• /user info → View user info
• /user ban → Ban a user

This way, you put several features inside a single command group!

🧩 Subcommands? What Are They?

A subcommand is a structure you use in the form /명령어 서브명령어 (that is, /command subcommand). The more features your bot has, the more useful they get, because they keep everything neatly organized!

🧑‍💻 Example Code

import discord
from discord.ext import commands
from discord import app_commands

class UserCommandGroup(app_commands.Group):
    def __init__(self):
        super().__init__(name="user", description="A collection of user commands!")

    @app_commands.command(name="info", description="Shows info about a user.")
    async def info(self, interaction: discord.Interaction, user: discord.User):
        await interaction.response.send_message(f"{user.name}'s ID is {user.id}.")

    @app_commands.command(name="ban", description="Bans a user.")
    async def ban(self, interaction: discord.Interaction, user: discord.User, reason: str):
        await interaction.response.send_message(f"Banned {user.name} for '{reason}'!")

intents = discord.Intents.default()
bot = commands.Bot(command_prefix="!", intents=intents)
bot.tree.add_command(UserCommandGroup())   # Register the group before sync()!

@bot.event
async def on_ready():
    await bot.tree.sync()
    print(f"✅ {bot.user} is ready!")

bot.run("YOUR_TOKEN")

🚀 Usage Examples

1. /user info user:@JohnDoe → JohnDoe's ID is 1234567890.
2. /user ban user:@JohnDoe reason:swearing → Banned JohnDoe for 'swearing'!

🎁 Bonus Tips

• You can set the group name with name="..." and its description with description="..."!
• To add commands inside the group, use the @app_commands.command() decorator.
• They're perfect when you're grouping things like admin features, game commands, and settings commands on a real server!

📌 Wrapping Up

Subcommands become a must as your bot grows more features! Grouping your commands neatly makes your bot feel much more polished.
