They "spawn" like other global non-interaction spawned dungeons where they check for other dungeons in the region and if there are none they spawn on a valid tile, expect instead of looking for valid tiles, they look for valid houses.Audiosmurf wrote:I get what you're saying, but I'm pretty sure I'm either 100% correct, or there's something specific to rat dungeon spawn mechanics, the latter due to their mention somewhere of not thinking there was any benefit to mass building houses, which would be a purely absurd thing to say if they worked like other dungeons.
The only added mechanic in the rat dungeon spawning is that it checks for an object (house) and then checks for a free tile inside said house, although that's not too different from checking for a water tile and then if there are enough empty water tiles around it for a beaver dungeon.
