Wall segment with door/window openings and a fixed collider.

Flat floor slab with a fixed collider; optional stairwell opening.

An arc of wall around the origin — solid concrete or a floor-to-ceiling glass curtain wall with mullions. Compose several arcs to leave door gaps; chords carry cuboid colliders.

A rounded structural plate (pill or ellipse) for curved-modernist decks, cantilevered roofs, terraces, or a lawn disc. Walkable, with a single convex-hull collider.

A stackable wall ring plus optional slab: per-side openings, sides that can be omitted, and a stairwell hole — the unit a building is composed from.

Flat or gable roof.

Door panel within a frame.

Window with frame and translucent pane.

Stepped staircase with per-step colliders: solid (a built-in stair on a floor) or floating (thin treads on sloped stringers, open underneath, to span a void).

An A-frame ridge tent: striped wind-rippled fabric, entrance flaps pinned open, guy ropes and stakes; solid sides and back, open front.

A wooden post-and-plank signboard carrying a name in the world's display font; the post sits behind the board so the text reads clean.

Posts and rails with seeded weathering; encloses yards and paths. One footprint collider.

A cloth flag on a pole; the cloth ripples per-frame, pinned at the luff. Thin pole collider.

Plank deck spanning a gap, optionally arched, with railings and slab colliders that follow the deck.

Freestanding gateway: two piers and a semicircular arch of voussoirs. Composes with Wall.

Column with a plinth, a tapered (optionally fluted) shaft, and a capital.

Stone well with a dark pool, posts, a little pyramid roof, and a bucket on a rope.

A tapered tower with a conical cap and four sails that turn each frame; tower collider, seeded blade phase.

A plank jetty on pilings reaching out over water; walkable deck colliders, side stringers, and seaward mooring posts.

Procedural analog wall clock; hands track the system clock or a given IANA timezone.

In-world text rendered in a world font (the one font-using component); falls back to the default bundled in @runek/core.

Lamp that emits a point light.

A ceiling fitting hanging from its origin: a flush dome, a pendant shade on a cord, or an aimed spot can. Can light only after dusk.

A hanging chandelier: a chain, a turned brass body, one or two rings of curved arms with candle bulbs, and optional glass drops. Instanced, with one shared light; can light only after dusk.

A banker's desk lamp: a brass base and stem under a cased glass shade with a pull chain, pooling light on the desk. Can light only after dusk.

Procedural striped rug (seeded stripes, no textures).

Wall shelf with planks.

Procedurally generated bookshelf with seeded books and one cuboid collider.

Bed with a frame, mattress, pillows, and a headboard.

A work desk: a top over slim legs, a drawer pedestal, or side panels, with a modesty panel at the back. Base and drawers seeded, each pinnable. One cuboid collider.

A desk monitor on a foot, plate, or legs. Switched on, the screen glows in its own color with a few seeded windows and lines of text on it, all geometry, or shows a texture the app hands it.

A sofa seating one to four: upholstered frame, seat and back cushions in soft shades of the fabric, square, rolled, or slim arms, pegs or a plinth, and throw pillows. Seeded, each choice pinnable.

A swivel office chair: five-star base on casters, gas column, padded seat, low or high back, optional arms. Seats a Person in sit or type pose.

A flat-screen TV on a stand, a low media console, or a wall. Switched on, it shows a seeded picture (sky, sun, hills) drawn from flat shapes, or a texture the app hands it.

A display of any size (a phone, a monitor, a TV, a digital frame, a billboard) on a wall, a stand, a desk foot, or in a frame. Shows a seeded picture or desktop, a text banner, animated static, or a color, or a texture the app hands it.

A wall print of seeded flat art (shapes, color bands, a retro sunset, mountain peaks) with an optional caption and a slim or wide frame.

A whiteboard on a rolling stand or a wall, with seeded marker diagrams (boxes, arrows, lines of writing) and optional text across the top.

A countertop coffee machine, espresso or drip, with a cup or carafe and a few puffs of steam. Sits on a Counter.

An upright arcade cabinet cut to the classic profile, with a lit marquee, joystick and buttons, and a screen running a pixel game laid out from the seed: invaders, falling blocks, a maze, a snake, or a paddle duel.

A pool table with rails, cushions, six pockets, and sixteen instanced balls, racked or scattered mid-game.

A regulation table tennis table with its lines, a net, a folding undercarriage, and paddles and a ball left on it.

A games console (tower, slab, or cube) with up to four controllers laid out in front, to sit under a TV.

Tableware to set a table: a plate, bowl, glass, cup, or water jug turned from a profile, or a whole place setting. Drinks fill to a line; plates and bowls stack.

Staved barrel bellied at the middle, banded by metal hoops; convex-hull collider.

Potted plant: a tapered planter and a seeded cluster of foliage.

Camera-following animated-shader ocean that reaches the world fog horizon (no textures); sits at the world ground.

Sloped beach/shore strip to meet a Lake.

A loose flock circling overhead, each bird flapping on its own seeded orbit.

L-system trees grown by a 3D turtle, deterministic from seed.

Clustered foliage blobs, seeded; the mid-height density between Grass and Trees.

Instanced seeded wildflowers (stem + colored head) scattered over a patch.

A trimmed green wall with seeded surface tufts; blocks like a Wall.

Procedural fbm-displaced ground with a matching trimesh collider, a flat build-pad option, and an optional radial island falloff. Its surface is queryable (`useGround`, anchors, `runek check-world`).

A rocky promontory: a low-poly, seed-jittered truncated cone with a flattish plateau and a convex-hull collider.

A meandering ribbon trail from seeded waypoints; decorative, laid just over the ground.

First/third-person character controller (ecctrl wrapper). WASD moves; mouse-drag or the arrow keys steer the camera in either view. Reads the world's `avatar` setting for its default view and the world's `controls` for key bindings.

A sculpted, clothed, skinned figure generated from a seed: one continuous body with a sculpted face, lidded eyes that follow you, and hands with fingers, in three style templates (stylized by default, realistic, anime). Every part is configurable as plain JSON: the body (build, tone, height), the face (eyes, brows, nose, lips, blush), hair, and clothing as ordered layers (shirts, sweaters, vests, coats, dresses, robes, trousers, jeans, skirts, shoes, boots, belts, scarves, capes) that fit any body. Role presets, swappable cosmetic skins, hats and accessories, poses, idle breathing and blinking. Give it a patrol or a wander radius and it walks: a route that is a pure function of the clock, following the ground, with a walk cycle and a step aside for the player and other walkers. A route with a departure time is a one-way trip (to a desk, to bed) that reports its arrival, and actions put a key prompt over it (Talk, Info) when the player comes near. Meshes build in the background, coarse first, with full detail near the camera. Place one at a spawn point, or use it as the Player's third-person body.

A travel gate: a glowing vortex around a dark core that fires onEnter (or navigates to a destination) when the avatar or a vehicle passes through — for world-to-world travel, level transitions, and teleports.

A pair of linked rifts torn in the air, ragged and edged in iridescent, glitter-shedding light. Each shows the other end live and in parallax, and walking into either carries you to the other: walkable shortcuts within one world (use Portal for other worlds or pages).

A screen-fixed HUD compass: a glassy dial in a corner of the canvas whose rose card swings with the camera heading, with a fixed lubber line and an optional wind + bearing readout — works with any traversal that drives the camera (on foot or at a vehicle's chase-cam).

Sun + hemisphere/ground fill with shadow configuration.

Wrap anything to make it something the player can act on: walk within range and a prompt shows its actions with the keys the world binds to them; press one and onAction gets its id. Only the nearest in range takes the key, and keys yield to text fields.
