contactRadius(waterY: number) → number

The collar sits on the stone, so its radius is whatever the tower is wide at the water's height: bare pillar below the shoulder, built floors above.

oceanAxis( ) → void

A grid whose spacing is uniform across the playable water and expands geometrically outward, so the swell is well sampled where the tower is and the sea still reaches past the horizon without a million triangles.

sheetMesh(axis: { number }, uvWorld: boolean) → any

A flat sheet on the XZ plane from an axis of X/Z coordinates. `uvWorld` writes the field position into the UV set, which is what tid_ocean's vertex stage hands the fragment stage as its wave field.

bandMesh(segments: number) → any

An open cylinder of unit radius spanning y = -1 .. 1. uv.x runs once around so the collar shader's wrapped noise closes on itself; uv.y runs bottom to top so `line_pos` can place the waterline inside the band.

quadMesh( ) → any

A unit quad on the XY plane, uv.y up — the rain curtain's canvas.

wingMesh( ) → any

One swept gull wing reaching along +X from a root at the origin, so the entity carrying it rolls about Z to flap. Flat: at gull scale against a grey sky the silhouette is the whole read.

birdBodyMesh( ) → any

The gull's body: a thin dart pointing along +Z.

spawnDrawn(name: string, parent: any, mesh: any, material: any) → any

setProp(matKey: string, name: string, value: any) → void

tuneSky( ) → void

Flat, cold and high — and, critically, a groundColor that matches the colour the ocean's own aerial perspective fades to. The sea's far rim sits a hair BELOW the true horizon, so the sky's below-horizon band shows as a sliver behind it; matched, that sliver is invisible, and unmatched it is a dark bar across the whole width of the frame.

alive(e: any) → boolean

Whether a proxy this slice is holding still names a live entity. A scene reload destroys everything under WeatherRoot WITHOUT re-running this module body, so `built` can outlive its entities; touching one of those proxies raises, the entrypoint catches it as "slice update failed", and the sea stops moving for the rest of the session with nothing on screen to say why.

install( ) → void

squallNow( ) → void

Bring a squall in now, unless one is already crossing. The staging slice can call this to put weather behind a beat; the sea calls it itself when a floor goes under.

cameraPos( ) → void

Where the camera is, so the rain curtain can be hung across the frame whatever the staging slice is doing with it. Read-only: staging owns that entity and this slice never writes to it.

update(dt: number) → void
