So I got an idea on how to make “roaming hordes” sorta work using a frankly ugly combination of two systems, the NPC system and the Fungal Bloom system. First up, have the game create a “Horde Master Zombie” Something boss-level, the idea I had in mind was a Zombie in Heavy (unpowered) power armor and above average health. Said zombie will act as a mobile “fungal spire” which will spawn regular zombies around it. Said Zombie will progress from wherever it spawns to the nearest city center (probably a building in it, NPC code) carrying the ‘horde’ with it, and leaving behind a handful of loose zombies that spawned around it (fungal bloom spread) wherever it wandered. Once it reaches a city (it’s targeted building) it will linger there for a period of time (half a season?) then move onto a new city, dumping off a large horde in the city in the process. (Which will “repopulate” formerly cleared cities.)
“Ekarus this is a suggestion” Sort of. I want to implement this myself, but beyond looking at the NPC code I don’t really know what to do, I could use some pointers on where to start, and what to do… But if you guys think I’m horribly in over my head I’d understand.
