HeartwoodEcosystem Platform for Vintage Story

Persistent populations, habitat-aware spawning, and autonomous villages — powered by a 24/7 simulation server.

Persistent Populations

Wildlife populations are simulated 24/7 by a Go server using logistic growth models. Animals persist across chunk loads, server restarts, and player sessions.

Habitat-Aware Spawning

The world is divided into habitat patches based on climate. Species spawn only where their ecological niche matches — wolves in cold forests, gazelles in arid grasslands.

Predator-Prey Dynamics

Wolves hunt deer, foxes hunt hares, owls hunt songbirds. Predation events are tracked and logged. Player hunting pressure reduces local populations.

Birdwatching Journal

Wingspan adds a discovery system — hold your gaze on a bird to record it. Six ranks, world map pins, behavioral notes, and a searchable life list.

Denning & Herding

Fauna gives land animals persistent homes. Wolves dig dens in hillsides, hares dig burrows, bears establish caves. Social species form herds with cohesion AI.

Autonomous Villages

Settlement places NPC villages during worldgen. Settlers walk the road network, perform specialized jobs, and build structures from player-directed work orders.
