More Forks

Percymon is a Pokemon battling AI that plays matches on Pokemon Showdown. Percymon is built using Node.js. Check out the full project write-up here.

Setting up the repository

To set up the server, you need to first install dependencies:

npm install

In order to actually play games you must create an account on Pokemon Showdown. Once the log-in information has been obtained, you need to create an account.json file containing information. The format of account.json is as follows:

{
    "username" : "sillybot",
    "password": "arbitrary password",
    "message" : "gl hf"
}

The message field indicates the message that will be sent when the bot first connects to the game.

Finally, to start the server, issue the following command:

node bot.js

By default, the server searches for unranked random battles when the option is toggled in the web console. There are several command line options that can be supplied:

--console: Only start the web console, not the game playing bot.
--host [url]: The websocket endpoint of the host to try to connect to. Default: http://sim.smogon.com:8000/showdown
--port [port]: The port on which to serve the web console. Default: 3000
--ranked: Challenge on the ranked league.
--net [action]: Neural network configurations. 'create' - generate a new network. 'update' - use and modify existing network. 'use' - use, but don't modify network. 'none' - use hardcoded weights. Default: none
--algorithm [algorithm]: Can be 'minimax', 'greedy', or 'random'. Default: minimax
--account [file]: File from which to load credentials. Default: account.json
--nosave: Don't save games to the in-memory db.
--nolog: Don't append to log files.
--startchallenging: Start out challenging, instead of requiring a manual activation first.

showdownbot's Issues

Can't start a battle...

This project looks great! I am building a similar project for a year long AI course. I tried running the bot and got a few problems. This issue appears to be that I can't start a battle because it can't find a room/doesn't know how to pick a format. I understand that you may not want to rework the code. But I would be super grateful if you would point me in the right direction. Below the error I got and the settings I used in the command line:

[FATAL] bot - Error logging in

Hi, I've created a bot but it can't log in. It comes up with warnings about not recognising commands of type 'formats' and 'queryresponse', and I don't know what to do. Please help!

What's wrong...
