Re: Ideas for an AI scheme

I had been planning to write the XML files by hand (it's a hobby game, 
so the only game designer is me) - but judging by Indy's response it 
looks like I should think about writing a tool.

I'm hoping to write the code myself for this game rather than use 
middleware because I want to understand how it all fits together (part 
of the reason I'm writing the game is to make sure I've seen how to 
write as many different subsystems as possible, because I want to 
understand what everyone else is doing ultimately) - but I'd be 
interested to see how it's done properly nonetheless. I'll take a look :)

Cheers,
Stuart
