packages/ai/src/visibility ​

How far one sees and hears in the room's light and weather (GAME_DESIGN §5.7: gently): a share of every sight range (a guard's and a camera's cone, a chaser's line of sight, a witness's reach) and of every hearing range.

  • Night: where the room's sky darkens sight (RoomWeather.night: a level that ships), the dark brings sight down to VISIBILITY.night of its reach, eased through dawn and dusk (@foi/shared's daylightAt); under a street lamp (@foi/world's lampLightAt) only to .lamp. What counts is where the one seen stands: a player in the dark is hard to see, one under a lamp is not. A lamp knocked down (its light piece lying loose, @foi/sim's isPieceLoose) is out: where it lit is dark again, until a level reset plants it.
  • Fog takes up to half of it away, rain a quarter in a downpour.
  • Hearing: rain masks footsteps and shots, up to .rainHearing of the range.

The client draws the cones with the same share (stealth-view.ts, the minimap). Deterministic: the clock, the weather the simulation read this tick (sim.sky) and the level.
