Bunnyland Festivalsim

Out-of-tree Bunnyland plugin that hangs seasonal festivals and community events on the world clock — recurring occasions with decorations, gifts, and contests that pull characters together. An expansion-pack-sized social pack that gives the calendar a heartbeat and a reason for everyone to be in the same room.

The bundle:

• A calendar of festivals — a FestivalConsequence reads the world clock and season and opens and closes festivals on a schedule (Spring Bloom, High Summer, Harvest Fair, Midwinter), setting a FestivalComponent singleton and emitting world events.
• Decorations — a decorate verb hangs placeable DecorationComponent items (lanterns, banners) that raise a room's festive mood and show in descriptions.
• Gift-giving — a give-gift verb transfers a held item and warms the giver↔receiver SocialBond, warming it more during a festival.
• Contests — a ContestComponent event that other packs plug entries into via an open ContestEntry registry (register_contest_entry); enter-contest and judge-contest run a bake-off/biggest-fish/best-song, and the winner gets a trophy and reputation.
• Seasonal mood — a SeasonalMoodConsequence lifts everyone's AffectComponent while a festival is active.
• Host-your-own festivals (v2 headline) — a host-festival verb throws a festival in any room on any day, registered as a core storyteller incident (IncidentComponent) and written to world history with an imagegen illustration. attend-festival warms the guest↔host SocialBond, and end-festival resolves the incident.
• Fairground games (v2) — a play-game verb tries a GameBoothComponent booth; the win/lose outcome is a deterministic hash of player, booth, and prior plays, and a win drops a prize in your hands.
• Spectacle (v2) — a launch-fireworks verb dazzles the room, and (optionally, when starsim is loaded) a meteor shower overhead becomes a shared spectacle over live festivals.

The "contest entry" hook other packs plug into is an open component/registry in this package; sibling packs' derby/bake-off/gig/game achievements are folded into a live festival's contest by name, with no hard dependency on any of them (optional partners are declared as recommends, and a festival runs fully standalone). Festivals are driven entirely by the calendar and stable hashes (no wall-clock time, no randomness), so worlds replay deterministically.

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

Layout

• server/ — Python Bunnyland plugin package with the festival calendar consequence, the three contributed components, the decorate/gift/contest verbs, seasonal mood, prompt fragments, a worldgen enrichment hook, spawn factories, and tests.

Server Plugin

The plugin exposes bunnyland_festivalsim.bunnyland_plugins() and contributes:

• FestivalComponent, DecorationComponent, ContestComponent, ReputationComponent, HostedFestivalComponent, GameBoothComponent, SpectacleComponent.
• Typed edges: ContestEntry, Hosts, AttendsFestival, Participates.
• FestivalConsequence — opens/closes festivals on the calendar and emits FestivalOpenedEvent / FestivalClosedEvent.
• SeasonalMoodConsequence — lifts every active character's mood while a festival runs.
• MeteorShowerSpectacleConsequence — turns a starsim meteor shower into a festival spectacle (disabled with a logged warning when starsim is absent).
• FestivalStageReactor — folds sibling packs' achievement events into a live festival's open contest, purely by event name.
• decorate, give-gift, enter-contest, judge-contest, host-festival, attend-festival, end-festival, play-game, launch-fireworks — the player/AI verbs.
• register_contest_entry — the open hook other packs call to enter their own loot.
• festival_fragments, decoration_fragments, contest_fragments, hosting_fragments, game_fragments, spectacle_fragments — prompt fragments.
• FestivalWorldgenHook — dresses generated town squares with decorations and a contest.
• spawn_decoration, spawn_contest, spawn_booth, spawn_spectacle — spawn factories.

Running

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

bunnyland serve --module bunnyland_festivalsim

default_enabled=True, so no --plugin flag is required once the module is imported. The bunnyland_festivalsim 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.
