game.audio.Sound

Everything First Light: Crowfeet is heard through. One component, on the scene's sound entity; nothing else in the game plays a sound.

The mix

Master 0.9. The bed sits under everything: it is the room, not an event.

The climb is audible with your eyes shut

Two ambience beds run at once and cross with the crow's height. amb_sea is loudest on the strand and thins to about a quarter of itself at the roost; amb_roost — air over the summit and a few birds that have not settled — comes up to meet it. So the last ledge sounds nothing like the first, and the light takes a little more of the sea away as it comes.

The score turns over with the light

music_night and music_dawn are the same sixteen-second drone on the same E, one with the minor third and one with the major. Both decks run in parallel and are crossfaded by CF.state.dawn between 0.15 and 0.85 — at dawn 0.5 each sits at exactly half. There is no track change: what the player hears is a third turning over as the sky does.

One line, spoken and printed

CF.say(speaker, text, key) fires line. The presentation slice prints the words; this component plays game/audio/voice/<key>.soundClip if one exists. The two are independent on purpose: a key with no clip is a line that is quiet, never a line that is lost. While a line is speaking the beds and the score duck to 0.40 and come back.

The nine keys are open_1, hunger_low, eat_1, crumble_1, first_light, won_1, lost_sea, lost_starved and lost_late.

What it answers

hop · land (by hardness — soft under 0.5, hard over) · grab · pullup · drop · peck · eat (by food.kind: grub / limpet / crowfoot) · crumble · fall · tooWeak · hungerLow · firstLight · phase (the flock lifting on a win; the sea, the collapse or the murder leaving without you on each loss) · reset · pause · line · ui.

CF.emit("ui", which) takes move / confirm / back / pause and their aliases (nav, select, start, restart, cancel, resume, menu, …); anything else answers with the quiet tick, so a new screen is never silent.

What another slice can ask of it

local sound = entity.find("sound").component.get("game.audio.Sound")
sound.speaking()          --> the line key being spoken, or nil
sound.play("caw", 0.6)    --> any recipe by name, for a noise with no event

Notes

Every source is non-spatial: the listener rides the camera and this is a mix, not a room. The beds loop with the Audio component's own looping field and are baked codec = "pcm" so they join without a click. Clips come from game/audio/recipes via game/audio/bake.luau; the voice lines were generated once and cached as assets — nothing is synthesised or generated at play time.

The blackboard is a module, and a module that reloads under a running session either becomes a new table or re-runs into the same one with an empty listener list. Either way a component that registered against the old bus hears nothing and says nothing about it — the whole soundtrack goes quiet with every reading still green. So this component does not trust its subscription: every couple of seconds it emits a private event through the module require hands back now, and if its own listener did not hear it back, it moves onto the live bus.
