Mapper

Generated from smudgy v0.4.1 (smudgy-mapper.d.ts @ b6d4245670a0). Index: scriptref.

The map API: import { mapper } from "smudgy:core". The map types (Area, Room, …) need no import.

declare const mapper: Mapper;

The current session's map API, as a global. Deprecated: import mapper from smudgy:core instead.

}

• createArea — Create a new area and return its handle.
• setCurrentLocation — Set the current map location (the per-session “you are here” marker).
• getCurrentLocation — The current map location, or undefined if none is set. room is absent when the location names an area without a specific room.
• areas — All active areas (areas marked inactive are excluded).
• getPathBetweenRooms — The cheapest route between two rooms, as a list of [areaId, roomNumber] steps (each exit's weight is its cost).
• deleteArea — Delete an area and everything in it.
• setRoomColor — Set a room's color to a CSS color string.
• setRoomProperty — Set a custom room property (string key/value).
• setAreaProperty — Set a custom area property (string key/value); the write counterpart of area.data(key). Pass an empty value to clear it.
• addRoomTag — Add a case-insensitive tag to a room (normalized to UPPERCASE; re-adding is a no-op).
• removeRoomTag — Remove a tag from a room (case-insensitive).
• findNearestRoomWithTag — The nearest reachable room carrying tag (case-insensitive) from from, by the same weighted search as getPathBetweenRooms (the start room counts if it carries the tag), or undefined if none is reachable. Path to it with getPathBetweenRooms.
• findNearestRoomWithTags — The nearest reachable room that carries every tag in all and none of the tags in none (all case-insensitive); undefined if no such room is reachable or the filter is empty. Used by multi-tag speedwalks like \inn.peace and \!peace.guild.
• findNearestRoomInArea — The nearest reachable room belonging to area from from, by the same weighted search as getPathBetweenRooms (from itself counts if it is already in the area, and naming the area reaches it even when it is marked inactive), or undefined if no room of the area is reachable. Path to it with getPathBetweenRooms.
• findRoomByExternalId — The room bound to a server-global room id (the room number games send over GMCP or MSDP), or undefined if no loaded room carries it. When the same id is bound in more than one area, one match is returned (rooms in your own maps win over shared ones).
• rescueRoomByExternalId — Reports whether a room with this server-global id is already mapped for a different server. When it is, the player is offered the chance to show that map here too, and this returns true, so a map drawn as you explore knows the room is accounted for and need not be recreated. Returns false when the id belongs to no other server's map.
• setRoomExternalId — Bind (or, with an empty string, clear) a room's server-global room id.
• createRoom — Create a room and return its new room number.
• updateRoom — Update multiple fields of a room in one cache update; only present fields change.
• updateRooms — Batch-update many rooms of one area in a single cache update.
• createRoomExit — Create an exit on a room and return its new id.
• setRoomExit — Update an existing exit. Returns nothing.
• deleteRoom — Delete a room.
• deleteRoomExit — Delete an exit from a room.
• createLabel — Add a text label to an area and return its new id.
• createShape — Add a graphical shape to an area and return its new id.
• deleteLabel — Delete a label from an area.
• deleteShape — Delete a shape from an area.
• setLabel — Update an existing label; only present fields change.
• setShape — Update an existing shape; only present fields change.
• exportArea — Export an area as a portable AreaJson. Requires copy rights on the area.
• importAreas — Import exported areas as new local areas (fresh ids). Exits between areas in the set are relinked to the new copies; exits pointing outside the set are kept but left unlinked. Returns the new area ids. Prefer this one-call form for multi-area imports.
• importArea — Import one exported area as a new local area; returns its id.

declare class Area {
    private constructor();

    room(roomNumber: number): Room | undefined;
    data(key: string): string | undefined;
    readonly labels: Label[];
    readonly shapes: Shape[];
    toString(): string;
}

A map area. You get areas from the mapper (mapper.areas, mapper.getAreaById), never by constructing one; the global Area class exists so checks like area instanceof Area work.

• isEphemeral — Whether this is a session map: it lives only for this session and is discarded when the session closes. Save it with mapper.exportArea + mapper.importAreas to keep it.
• next_room_number — The next unused room number in this area.
• room — The room with this number, or undefined.
• data — Read a custom area property by key (or undefined if unset).
• labels — This area's text labels.
• shapes — This area's graphical shapes.

}

A room read from the map. Obtain one via area.room(n) or the listRooms* helpers.

• color — A CSS color string.
• data — Read a custom room property by key (or undefined if unset).
• tags — This room's tags, normalized to UPPERCASE and sorted.
• hasTag — Whether this room carries tag (case-insensitive).
• update — Update multiple fields of this room in one cache update; only present fields change.

interface CreateAreaOptions {
    ephemeral?: boolean;
}

The map API for the current session (each session has its own). Changes sync to the cloud in the background.

• ephemeral — Create a session map: it lives only for this session, is never saved or synced, and is discarded when the session closes. The place for maps built automatically from server data.

interface CreateRoomParams {
    title?: string;
    description?: string;
    level?: number;
    x?: number;
    y?: number;
