Could you add one for Mafia? (and no, not how to make mafia themes) I'd like to learn how to create commands, etc. and I don't fully understand anything while looking at mafia.js
These are "gerneral" guides that document the API and some standard usages of it. Mafia would be a specific guide for one specific script, more likely to end up on the wiki for that project, not here.
I'm actually working on a client script guide. Hopefully it will help those with low coding experience, while providing example commands. I try to add more examples and update when I can. http://pokemon-online.eu/threads/guide-how-to-make-auto-respond-bots.24548/
