deadlight.film — the demo's shared constants and its film clock. ONE module every slice of DEADLIGHT reads. It holds three things: 1. THE TIMING SPINE — how long each of the 14 shots runs and when it starts. Nobody else decides this. A slice asks `Film.shotAt(t)` or `Film.window(n)` and lays its work against the answer. 2. THE WORLD CONTRACT — the shared coordinate frame, the named entities each slice promises to put in the scene, the palette, and the water's optical constants. Four agents build one place; this is how they agree. 3. THE CLOCK — a FIXED 1/24 s step advanced once per RENDERED frame by `FilmDirector`. Never wall time. N rendered frames is always exactly N/24 film seconds, so the recording phase can run the film twice and get the same film. HOW YOU PLAY IT, from anywhere: local Film = require("deadlight.film") Film.restart() -- t := 0, every slice's reset() runs, playing := true Film.seek(41.0) -- deterministic scrub: restart, then step to 41.0 s Film.pause() / Film.resume() HOW YOUR SLICE JOINS IT, from your own component's awake(): Film.register("abyss", { reset = function() ... end, -- put the world back at t = 0 tick = function(t, dt) ... end, -- every 1/24 s of film time shot = function(n, tLocal) ... end, -- fires once as a shot opens }) Registering the same name twice REPLACES the old handlers, so a component that re-awakes on hot-reload does not double up. Every handler runs inside pcall: one slice erroring cannot stop the film for the other three.
