This is a version of PlayBot which works with Supybot/Limnoria which requires Python 2 or 3 to use.
There are 2 versions of the PlayBot: Single is for a Single player and Multi is for up to 5 players.
Instructions - Supybot/Limnoria
Here are some instructions on how to get this working if do not know already.
For PlayBotMulti you need to load the Network plugin
Unpack the archive and copy it to your supybot plugins directory.
Then load the plugin using the load <PlayBotSingle or PlayBotMulti> command.
When it is loaded a message should come up "The operation succeeded"
When setting up the supybot make sure you have in channel triggers turned off.
You shouldn't really use the NickCapture plugin as it is likely you will get lots of nick change penalties in the game when you recapture your original nick.
If you are having problems with the supybot disconnecting from the network, try increasing the ping.interval in the config file or you can change the setting with
config supybot.protocols.irc.ping.interval 500
Default is 120
To get the bot to play you need to use the command in the game channel /msg <supybot> <playbotsingle or playbotmulti> login name password
Obviously replacing the <supybot> with the name of your supybot, <playbotsingle or playbotmulti> with either playbotsingle or playbotmulti, name with your character's name and the password with your character's password.
