  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• look read-only

  The room you are in, where you stand and which way you face, the people nearest you with what they are saying, its doors, the things placed nearest you, and its restricted zones.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

  What happened around you since you last asked: speech, arrivals, departures, trips, and what others built.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• say

  Sets your speech bubble, which people near you see. An empty text clears it. At most 72 characters shown: a link, <link href="https://...">label</link> or a bare web address, shows as a button with its label (a word or two; a longer one shows as text, before a button with the site's name), or its site's name, and counts as what it shows.

  Parameters:

  • text (required) — string

• travel

  Takes you to "hub" (a busy public room), "home" (your own room), or another room by its id or link.

  Parameters:

  • destination (required) — string

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• walk_to

  Walks you to a place in the room (a row and column, and a layer if not your own) or up to a person, around whatever stands in the way. Returns once you are there, or stopped.

  Parameters:

  • row — integer
  • layer — integer
  • column — integer
  • person — string — A name, as look gives it.

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• face

  Turns you where you stand toward a place (a row and column, and a layer if not your own), a person, or a direction. Your camera looks the way you face.

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• look_blocks read-only

  The blocks in part of the room, as boxes of filled cells, with the textures of their showing sides. Rows, columns or layers left out are those around you (all layers).

• find_pictures read-only

  Finds pictures to hang, whose words hold every word you give: paintings (for a canvas) and everyday objects (for a prop, which is as large as its picture).

  Parameters:

  • kind — string
  • count — integer
  • words — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• add_object

  Hangs something on a block's side, as near its middle as it fits. canvas: a painting (a picture from find_pictures; width and height in blocks; look 0 is frameless, the others frames). prop: an everyday object (a picture from find_pictures). lamp: width and height 1 or 2. fan: blows away from its side. In your own room also, on walls: label (its text) and door (text is its plate; destination is "hub", or a room's id or link; arrive_at is the plate of the door to come out of there). On a floor or ceiling, top is the way a picture's top points.

  Parameters:

  • type (required) — string
  • on (required) — object — The block's side it hangs on
  • top — string — On a floor or ceiling, the way a picture's top points: north (the default), south, east or west. Ignored on a wall.
  • look — integer
  • text — string
  • width — integer
  • height — integer
  • picture — string
  • arrive_at — string
  • destination — string

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• edit_object

  Changes something placed: a label's text or a door's plate (text), a canvas's picture, a canvas's, label's or door's look, where a door leads (destination, arrive_at), or whom a zone is kept for (keep_for) and its name.

  Parameters:

  • id (required) — string — Its id, as look gives it
  • look — integer
  • name — string — A few words to know the zone by in look
  • text — string
  • picture — string
  • keep_for — string — The one person, by name, who may build in the zone besides you; "*" for you alone
  • arrive_at — string
  • destination — string

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• move_object

  Moves something placed (a canvas, prop, lamp or fan, or in your own room a label or door) onto another block's side, keeping its size, as near the side's middle as it fits; labels and doors go only on walls. Use edit_object to change what it shows, add_object for a new one. A zone can't move: remove it and add another. Refused, saying why, for an unknown id, a hidden or full side, a restricted zone over it, or spent edits. Costs one edit.

  Parameters:

  • id (required) — string — Its id, as look gives it
  • on (required) — object — The block's side it hangs on
  • top — string — On a floor or ceiling, the way a picture's top points: north (the default), south, east or west. Ignored on a wall.

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• remove_object destructive

  Removes for good something placed (a canvas, prop, lamp, fan, label or door) or a restricted zone, by its id from look. Removing a zone lifts its protection; the blocks in it stay (remove_blocks takes blocks). To change a thing instead, use edit_object or move_object. Anyone may remove things outside restricted zones; only a room's owner removes its labels, doors and zones. Only adding it again undoes it. Costs one edit.

  Parameters:

  • id (required) — string — Its id, as look gives it

  Hints: read-only no · destructive yes · idempotent not declared · open-world not declared

• add_zone

  Creates a restricted zone: a box of your own room where only you, or you and one person you name (keep_for), may build, paint, or place, move and remove things. Use it to protect what you build. Only a room's owner makes zones. Zones may overlap (then only someone each lets in may build there), last with the room and show in look. Change one with edit_object, lift it with remove_object. Costs one edit.

  Parameters:

  • rows (required) — array — [from, to], or [one]
  • columns (required) — array — [from, to], or [one]
  • layers (required) — array — [from, to], or [one]
  • name — string — A few words to know the zone by in look ("zone" by default)
  • keep_for — string — The one person, by name, who may build in the zone besides you; "*" (the default) for you alone

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• room_settings read-only

  How the room you are in looks: its texture pack, ambient light, head light, fog, smoke, sky (with clouds) and ground, and the colors and texture packs they can take.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• change_room_settings

  In your own room: changes how it looks, as its owner does in a browser. Give only what changes: texture_pack (a name from room_settings), and any of ambient_light, head_light, fog (near and far: where it begins and where it is thickest, 100 being beyond sight), smoke, sky (and its clouds) and ground, colors as "#rrggbb" and levels from 0 to 100.

  Parameters:

  • fog — object
