DeepThonk: A Python bot for Twitch

An open-source Python bot framework for Twitch - currently in development. In it's current version, it's a rewrite of the "OG" version we build on-stream in 2018. Some features are missing until we can port them over to the rewrite.

Deepthonk was Live Coded on Twitch, with the help of an amazing community!

Feature Overview

In Production

A simple call & response command system
Text-to-speech (TTS) system
SFX/hooks commands system (using browser source in OBS)
Shoutouts to subscribers & team members (chat & tts)
Basic event reactions (raids)

In Development

Random sound effects based on trigger words in chat
OBS scene & source control (done but not ported)
Philips HUE integration (done but not ported)

Integrations

Twitch IRC chat & API
Streamlabs alerts (partial functionality, still working on remaining alerts)

Configure the bot

To run the bot, you need to run both the local server and the bot application simultaniously. The bot app handles integration with the chat, and the server handles generating the OBS Browser Source for the sound effects and other critical functionality.

Prerequisites

Python 3.6 or 3.7 -- Windows // Linux // OS X
PIPENV ->pip install pipenv or python -m pip install pipenv (sometimes python3)
An oauth token & client-id for a Twitch account for your bot
- This Twitch Bot Tutorial I made on dev.to explains how to obtain your tokens and ID

Create a cozy home for the bot to live in

Virtual environments require a couple extra steps to set up but make developing Python apps a breeze. I suggest using PIPENV which marries pip and venv into a single package.

You'll need to do the following steps for both the bot and the server directories

In the console, navigate to your working directory
Then run ⇒ pipenv install

Repeat this for both /bot/ and /server/ directories

Adding secrets & settings

Rename the .env-example files to .env in the /bot/ and /server/ directories.

Your secrets will live inside these files and imported into the venv when you start the apps. Add the oauth token and client-id from above go after the = in the files. Fill in the other variables as well.

# /server/
SECRET_KEY= # make up your own key here

# /bot/
TWITCH_BOT_NICK=
TWITCH_TOKEN=oauth:
TWITCH_CLIENT_ID=
TWITCH_PREFIX=! # default is !
TWITCH_CHANNEL=
TWITCH_TEAM=
STREAMLABS_KEY=
BOT_SERVER_KEY=  # use key from /server/.env

Booting up the bot

Start the server:

Navigate to the server's working directory (/server/)
In the console, run ⇒ pipenv run python server.py

Start the bot:

Navigate to the server's working directory (/bot/)
In the console, run ⇒ pipenv run python deepthonk.py

Once the bot goes online, it should greet you in both console and the configured channel's chat.

Test command

The bot comes pre-loaded with a !test command, if you want to try it in chat.

Adding custom commands

Create new commands at the top of commands.py. Any command you make needs to follow this format when defining them..

Decorated with @bot.command(name='whatever')
Be asynchronous functions with names that match the name variable in the decorator
Pass the message context in through the function

How the function works and what it does is all up to you. For this example, we'll create a command called !test that says test passed! in chat when we call it.

# bot.py, below event_message function
@bot.command(name='test')
async def test(ctx):
    await ctx.send('test passed!')

One key ingredient to making any command work is for them to be handled in the event_message function. If you accidently delete the following line, and commands don't work anymore, that's what's up.

# events.py, inside event_message
await bot.handle_commands(ctx)

Adding SFX

Place SFX inside server/static/hooks/.

Mp3s, WAVs, and Ogg files inside that folder are loaded as sfx commands when the server starts.

Setting up in OBS

Inside OBS, create a new browser source with the url of http://localhost:6969/obs-source/. You should be able to hear sfx now.

If you make any changes to the server and add or remove SFX, you'll need to refresh the browser source's cache.

Events

There are 2 events that are used in the code right now.. on_ready and on_event.

on_ready

This executes when the bot comes online, and will print out to the console.

@bot.event
async def event_ready():
    print(f'Ready | {bot.nick}')

event_message

This function executes once per event (or message) sent. You can make it handle input from chat that aren't necesarily commands, and fun stuff like that.

@bot.event
async def event_message(message):
    print(message.content)
    await bot.handle_commands(message)

You can find more info in TwitchIO's official documentation.

Advanced topics

I'm working on a blog and tutorial series going over more advanced topics in Python Twitch bot building and the TwitchIO library on dev.to

Let's make a Twitch bot with Python!

Follow Along & Contribute!

Watch & help develop the bot during live streams on Twitch! PR's are welcome but you're encouraged to at least spend a little time on stream to get an idea about Deepthonk's "personality" and the direction we're taking the bot first.

If you have any questions or just wanna brainstorm some neat ideas, live-streams are the best time for that!

Trouble-shooting

I'm still working on building out this section of the docs. If you have any questions or issues, you have a couple of options to get in touch with me...

Create an issue in the repo (slow but well-documented)
Twitter (pretty fast)
Discord, in the #dev channel (faster)
Twitch Streams, (schedule pinned on Twitter) (fastest)
