What it does

game.vicar — the Hollow Vicar

The thing that walks the lanes of Lanternwake. One model, generated entirely in Luau: a tall, wrong clergyman with no feet, whose hem pools in the fen water and drags behind it, and who carries a cold blue-green light where a face should be.

What it puts in the scene

An entity named HollowVicar under the Vicar container. That name is the contract with the hunt slice, which drives its position and rotation. Everything below the root belongs to this module:

HollowVicar                 ← hunt moves this, and only this
└ VicarBody                 ← breath, lean, sway, the constant half-turn
  ├ VicarCassock            the skirt, hem to throat
  ├ VicarMozzetta           the shoulder cape, a shell with a scalloped edge
  ├ VicarTatters            strips of rotted hem floating behind it
  ├ VicarClasp              the only metal on the figure
  ├ VicarHead               turns toward you when it is hunting
  │ ├ VicarHood             a shell with a 26 mm wall and a black interior
  │ ├ VicarFace             the glow
  │ └ VicarFaceLight        the point light the fog needs it to carry
  └ VicarArm{L,R}           ├ VicarFore{L,R} ├ VicarHand{L,R}

Roughly 32,000 triangles across twelve runtime meshes, built once and cached.

How it animates

Nothing here decides where the Vicar is. update(dt) reads the root's motion back and animates the body around it, so the hunt slice only has to say where the thing stands:

what it is doingwhat you see
standinga slow swell through the shoulders, the head drifting
walkinga glide with a lateral roll — no footfall bob, it has no feet
stalking (vicarState == "chase")faster, pitched forward, arms thrown wider, the facelight up
noticing you (vicarSpotted)the head snaps round and the facelight flares hard

It reads Core.state.vicarState and listens for vicarSpotted and playerCaught. It emits nothing.

The materials

vicar_cassock, vicar_mozzetta and vicar_hood are three settings of one shader, vicar_wool — sodden Victorian serge with a diagonal twill, a capillary waterline, fen silt, mildew in the folds and a fibre sheen. It reads three channels baked into every vertex: .r height, .g ambient occlusion, .b fold depth. That is why one shader dresses a hood, a sleeve and a pooled hem at the right wetness without a per-part parameter set.

vicar_glowface is vicar_glow, a self-shading emissive. vicar_clasp and vicar_hand are pbr.

Debug handles

require("game.vicar").report()      -- root, position, triangles, speed, flare
require("game.vicar").flare(1.6)    -- make it notice you
require("game.vicar").invalidate()  -- drop the cached meshes, then build() again

zero/source-extract/v2

game/vicar.module — THE HOLLOW VICAR. One model, built properly. The thing on every screenshot. Everything here is generated: there is no imported mesh. The figure is a set of lofted surfaces — a cassock whose skirt pools and drags instead of ending in feet, a mozzetta over hunched and uneven shoulders, a narrow hood with real thickness and a dark interior, arms a foot too long ending in gaunt seven-jointed hands — plus the cold blue-green light where a face should be, which carries its own point light because the fog eats anything that does not. THREE THINGS THIS FILE OWES THE REST OF THE GAME 1. An entity named `HollowVicar` under the `Vicar` container. That name is the contract: the hunt slice finds it and drives its position and rotation. Nothing here moves it across the ground. 2. Everything below that root animates ITSELF from the root's motion — breathing at rest, a drifting walk, a faster stalk, and a flare when it takes an interest — so hunt only has to say where the thing is. 3. Every entity marked temporary, so the scene never bakes it. WHY THE GEOMETRY IS BUILT THE WAY IT IS Silhouette first. At thirty metres in fog this is a black shape, and the shape has to be wrong before any of the detail matters: too tall, too narrow, no feet, a hem wider than the shoulders, arms hanging past the knees, and a head that comes to a point in front of where a skull would be. Then the detail. Every surface carries three baked per-vertex channels the `vicar_wool` shader reads: vertex_color.r height, 0 at the hem lying in the water → 1 at the crown vertex_color.g baked ambient occlusion vertex_color.b fold depth, 0 on a crest → 1 in a valley and UVs laid in approximate METRES, so the weave is one physical size on the sleeve and on the skirt.

newMesh( ) → void

1. MESH CONSTRUCTION A tiny loft kernel. Every part of the figure is built from it. Winding is decided per triangle rather than assumed: the engine's meshes are wound so that cross(b-a, c-a) points OUT of the surface (verified against @builtin::meshes.sphere, 401/401 triangles), so each triangle is emitted in whichever order agrees with the outward hint carried on its vertices. That makes a shell with an inverted interior surface — the hood — come out right without a second code path.

vert(m: ?, x: ?, y: ?, z: ?, hx: ?, hy: ?, hz: ?, u: ?, v: ?, cr: ?, cg: ?, cb: ?) → void

Returns a ZERO-BASED vertex index, which is what the geometry format takes.

stitch(m: ?, rings: ?) → void

Stitch consecutive rings. Each ring is an array of S+1 indices where the last repeats the first at a full-circumference u, so the weave has no interpolation seam.

Smooth normals from the (now consistently wound) faces, plus a tangent basis derived from the UVs so the shader's cloth relief has a direction.

foldField(theta: ?, s: ?) → void

2. THE CLOTH FUNCTIONS One fold field, sampled by every woollen part, so the hood's creases and the skirt's are recognisably the same fabric. Three harmonics: the big drape, the crease inside it, and the crumple on top.

loftRing(m: ?, sec: ?) → void

Loft a run of sections into a closed tube. section = { c = {x,y,z} ring centre ax = {x,y,z} the ring's "sideways" axis, ALREADY scaled by radius az = {x,y,z} the ring's "forward" axis, ALREADY scaled by radius fold = number radial fold amplitude in metres v = number the v texture coordinate (arc length along the loft) ao = number baked ambient occlusion for the whole ring inv = boolean? point the outward hint INWARD (for a shell's interior) warp = function? (theta, section) -> extraRadialScale, extraOffsetY }

resample(profile: ?, sub: ?) → void

Resample a { y, z, rx, rz } profile into `sub` times as many sections, interpolating everything, so the fold field is sampled finely enough to read as cloth rather than as a fan of facets.

buildSleeve(profile: ?, side: ?, opts: ?) → void

A sleeve, lofted along its own bend. Local origin is the joint it swings from, so the animation is a rotation and nothing else.

buildHand(side: ?) → void

Long, thin, and jointed. This is where a close capture is won or lost: everything above is drapery, and drapery can be faked, but a hand cannot.

tube(pts: ?, ao: ?, baseY: ?) → void

Local loft for the small round parts. Sixty-four segments on a finger would be four thousand triangles per digit for nothing.

Round both ends off.

buildClasp( ) → void

The only metal on the figure, and the only thing on it that was ever polished. A tarnished ring with a drop hanging out of it, at the throat.

buildFace( ) → void

A small flattened ellipsoid. u = 0 faces forward, and the glow shader puts its bright core on the equator at u = 0, so the light points out of the hood while the poles stay dark.

buildTatters( ) → void

Strands of the hem that have come away and now drag behind it in the water. They are what makes the thing read as MOVING when it is barely moving: they are the only part of the silhouette that trails.

alive(e: ?) → void

An entity proxy held across frames goes stale the moment something despawns it, and then EVERY read on it raises. This module holds a dozen of them, so one guard on the root — which every other part hangs off — is what stands between a scene reload and an exception per frame forever.

stop( ) → void

report( ) → void

A debug handle. `require("game.vicar").report()` from an execute call.

invalidate( ) → void

Drop the cached GPU meshes so the next build regenerates them. Only for authoring: it is how a geometry edit is seen without reloading the world. The GPU resources are FREED, not just forgotten. `renderer.mesh.create` mints a new one every call, so a cache that is merely emptied leaks about 700 KB of vertex buffers per rebuild and there is nothing that enumerates live handles afterwards to find them again.

Did the part work as advertised when consumers tried to drop it in. Separate from upvotes: those are taste; this is "did it function".
