Bunnyland Wildsim

Out-of-tree Bunnyland plugin that adds an expansion-pack-sized wilderness survival pack. It layers four cohesive mechanics onto the core Relics ECS, reusing the server's light, weather, needs/meter, and health systems:

• Scent & trails — creatures leave a decaying scent in each room they pass through; carried tracking gear points down the exit toward the strongest-scented neighbour.
• Cold & warmth — a body-warmth meter drains in cold rooms (weather, night, biome, exposure) and is restored by fire or shelter; freezing bleeds health.
• Campfires — a lightable, fuel-burning fire that raises its room's light and warms everyone in it, with build-fire and stoke-fire verbs.
• Foraging — biome-seeded resource nodes yield items on a per-node cooldown via a forage verb.

This repo intentionally keeps all wildsim work outside the main bunnyland-server repo.

Layout

• server/ - Python Bunnyland plugin package with the survival components, the passive consequences (scent, warmth, campfire), prompt fragments, a worldgen enrichment hook, the player/AI verbs, and tests.

Server Plugin

The plugin exposes bunnyland_wildsim.bunnyland_plugins() and contributes:

• ScentComponent, ScentTrailComponent, TrackerComponent - scent & tracking.
• WarmthComponent - body warmth (reuses the shared needs/meter primitive).
• CampfireComponent - a lightable fire; ResourceNodeComponent - a forageable source.
• ScentConsequence, WarmthConsequence, CampfireConsequence - the per-tick passive sim.
• wildsim_fragments - renders survival state into both human and AI prompts.
• WildWorldgenHook - scents generated predators/prey and seeds resource nodes per biome.
• build-fire, stoke-fire, and forage - verbs for humans and AI.

Running

This package builds no containers. It is loaded into the stock server via --module:

bunnyland serve --module bunnyland_wildsim

default_enabled=True, so no --plugin flag is required once the module is imported. The bunnyland_wildsim package must be importable by the server (installed into the server's environment, or on PYTHONPATH).

Development

Run server tests against a sibling bunnyland-server checkout (no install required — server/tests/conftest.py puts both packages on sys.path). From server/:

uv run --project ../../bunnyland-server -m pytest
uv run --project ../../bunnyland-server ruff check src tests

See server/README.md for more detail.
