How do I change my bot from using text/prefix based commands to slash commands and buttons in discord.py?

August 14, 2022

I’ve seen most developers are switching their bots to using slash commands instead of the usual prefix commands. How do I rewrite my bot using slash commands? I have no idea how to get started with slash commands.

>Solution :

You need to install discord.py v2.0 by install the latest version: pip install -U git+https://github.com/Rapptz/discord.py.

Basic example (free function command)

import asyncio

from discord.ext import commands
from discord import app_commands

# define Bot with **needed** parameters
bot = commands.Bot(command_prefix="some_prefix", intents=some_intents_definition)

# You can now use `@bot.tree.command()` as a decorator:
@bot.tree.command()
async def my_command(interaction: discord.Interaction) -> None:
  await interaction.response.send_message("Hello from my command!")
### NOTE: the above is a global command, see the `main()` func below:


async def main():
  async with bot:
    # do you setup stuff if you need it here, then:
    bot.tree.copy_global_to(guild=discord.Object(id=...))  # we copy the global commands we have to a guild, this is optional
    await bot.start(MY_TOKEN)
