What is Dota Coach?

Dota Coach is a discord bot using Valve's Gamestate integration API that reminds you of important timings in the game (roshan timer, wisdom rune spawning, etc.)
It can also view your inventory and provide suggestions (i.e. buying a tp scroll if you don't have one)

How to install Dota Coach

(You only have to do this once)

Add bot to your server (or find a server that already has dota-coach added)
Go to any channel and type /config
Download the .cfg file to your computer
Open your Steam library
Right click Dota 2, click Properties
Make sure you are on General on the left sidebar
Add -gamestateintegration to the launch options
Click on Installed Files on the left sidebar
Click Browse... to open up the dota install folder in your file explorer
Navigate into the game/dota/cfg folder
If it does not already exist, create a new folder called gamestate_integration
Move the file downloaded from step 3 into the gamestate_integration folder
Restart Steam

Optional - enable voice commands

Give permission for the bot to send everyone's voice from discord to Google's Speech Recognition API, so the bot will respond to voice commands such as "what is roshan status" or "next wisdom rune"
This is turned off by default, and needs your explicit opt-in. If you would like to enable this, go to any discord channel, type /voice and select the True option

How to start Dota Coach

Join a voice channel (that the bot has permissions for)
Type /coachme in any text channel on the discord server
Click the private coaching link provided by the bot (do not share this link with anyone)
Click the "Start coaching" button on the website (you can bookmark this link for easy access)

You are now ready to play a game!

When you are done playing, you can type /stop to have the bot leave the voice channel (the bot also auto-disconnects if everyone leaves the voice channel or after 1 hour of inactivity)

You can configure each assistant to be public (played through discord to everyone in the voice channel), private (played through website to only you), or disabled
Starting the coach mid-game is not fully supported. Roshan status may be incorrect.

Autoconnect to your discord voice channel

The first time you do a /coachme, the bot sets that discord guild your "default guild"
The next time you start a game in your default guild, the bot will autoconnect to the voice channel you are in (so you do not need to do /coachme)
You can change your default guild with /autoconnectdefault
Use the /autoconnect False command to stop the bot from autoconnecting (you can still manually start the bot using /coachme)

Using the coach without Discord

If you type /coachme without being in a voice channel, you will still recieve a private coaching link.
You can bookmark this link and start private coaching directly from the web page at any time without using Discord
Make sure to set all enabled assistants to play "private" audio
The voice commands feature ("what is roshan status") will not work

Isn't this cheating?

This bot uses the official Dota 2 Gamestate Integration API. This is the same API that twitch streamers use for their overlays, and all the data is provided to us directly by Valve. It does not use any "hidden" data that would give you knowledge you should not have access too (i.e. enemy cooldowns or vision)

This bot has access to the same information a friend live-coaching your game would have. Your friends are allowed to live-coach your pubs with Dota+, but this sort of coaching may be against the rules if you are playing in tournament games (check with your admins)

Notes

This bot is still in beta. A new version of the bot is deployed daily at 5am Eastern, but occasional hotfixes may be pushed throughout the day. If you are playing a game at this time, the bot will restart and it may lead to unexpected behaviour
If two people use the /coachme command in the same voice channel, only the first person will be allowed to play audio through discord. The second person's private coaching link will still work, but their "public" announcements will be disabled
Turbo mode, custom games, or spectating a game will lead to undefined behaviour. Would not recommend.
If you have private discord voice channels you would like to use, you should give the bot permissions to access to those channels. You could also start in a public channel and drag the bot into the private one and it should work 99% of the time but there are some very niche edge cases where you will enounter wonky behaviour
