Also, yeah, the monster brain file probably should be mentioned. I left it out because it looks kind of “advanced” monster editing. Also, I haven’t been able to include a custom brain into the monster_brains_definition. Whenever I do that, whole AI system breaks down and crashes the game though I haven’t broken any apparent tags. Should the file be edited with some other program than notepad?
Not to my knowledge. I’ve been able to add a new zombie and have it prefer to do things based on the AI I set in the file using just open-office writer (notepad as well). Alas for me I can’t get the summoning other monsters to work properly, but I can tell it’s trying its utmost to do so.
