Mapper Functions

These are functions that are to be used with the Mudlet Mapper. The mapper is designed to be MUD-generic - it only provides the display and pathway calculations, to be used in Lua scripts that are tailored to the MUD you're playing. For a collection of pre-made scripts and general mapper talk, visit the mapper section of the forums.

To register a script as a mapping one with Mudlet (so Mudlet knows the profile has one and won't bother the user when they open the map), please do this in your script: <lua> mudlet = mudlet or {}; mudlet.mapper_script = true </lua>

addAreaName

areaID = addAreaName(areaName)

Adds a new area name and returns the new area ID for the new name. If the name already exists, -1 is returned.

addRoom

addRoom(roomID)

Creates a new room with the given ID, returns true if the room was successfully created.

addSpecialExit

addSpecialExit(roomIDFrom, roomIDTo, command)

Creates a one-way from one room to another, that will use the given command for going through them.

See also: [#clearSpecialExits|clearSpecialExits()]]

Example

<lua> -- sample alias pattern: ^spe (\d+) (.*?)$ -- mmp.currentroom is your current room ID in this example addSpecialExit(mmp.currentroom,tonumber(matches[2]), matches[3]) echo("\n SPECIAL EXIT ADDED TO ROOMID:"..matches[2]..", Command:"..matches[3]) centerview(mmp.currentroom) </lua>

centerview

centerview (roomID)

Centers the map view onto the given room ID. The map must be open to see this take effect. This function can also be used to see the map of an area if you know the number of a room there and the area and room are mapped.

clearRoomUserData

clearRoomUserData(roomID)

Clears all user data from a given room.

clearSpecialExits

clearSpecialExits(roomID)

Removes all special exits from a room.

createMapLabel

labelID = createMapLabel(areaID, text, posx, posy, fgRed, fgGreen, fgBlue, bgRed, bgGreen, bgBlue)

Creates a visual label on the map for all z-levels at given coordinates, with the given background and foreground colors. It returns a label ID that you can use later for deleting it.

The coordinates 0,0 are in the middle of the map, and are in sync with the room coordinates - so using the x,y values of getRoomCoordinates() will place the label near that room.

createMapper

createMapper(x, y, width, height)

Creates a miniconsole window for mapper to render in, the with the given dimensions. You can only create one at a time at the moment.

Example

<lua> createMapper(0,0,300,300) -- creates a 300x300 mapper top-right of Mudlet setBorderLeft(305) -- adds a border so text doesn't underlap the mapper display </lua>

createRoomID

usableId = createRoomID()

Returns the lowest possible room ID you can use for creating a new room. If there are gaps in room IDs your map uses it, this function will go through the gaps first before creating higher IDs.

deleteArea

deleteArea(areaID)

Deletes the given area, permanently. This will also delete all rooms in it!

deleteMapLabel

deleteMapLabel(areaID, labelID)

Deletes a map label from a specfic area.

deleteRoom

deleteRoom(roomID)

Deletes an individual room, and unlinks all exits leading to and from it.

Example

<lua> deleteRoom(335) </lua>

getAreaRooms

getAreaRooms(area id)

Returns an indexed table with all rooms IDs for a given area ID (room IDs are values), or nil if no such area exists.

Note: On Mudlet versions prior to the 2.0 final release, this function would raise an error.

Example

<lua> -- using the sample findAreaID() function defined in the getAreaTable() example, -- we'll define a function that echo's us a nice list of all rooms in an area with their ID function echoRoomList(areaname)

 local id, msg = findAreaID(areaname)
 if id then
   local roomlist, endresult = getAreaRooms(id), {}
 
   -- obtain a room list for each of the room IDs we got
   for _, id in ipairs(roomlist) do
     endresult[id] = getRoomName(id)
   end
 
   -- now display something half-decent looking
   cecho(string.format(
     "List of all rooms in %s (%d):\n", msg, table.size(endresult)))

   for roomid, roomname in pairs(endresult) do
     cecho(string.format(
       "%6s: %s\n", roomid, roomname))
   end
 elseif not id and msg then
   echo("ID not found; " .. msg)
 else
   echo("No areas matched the query.")
 end

end </lua>

getAreaTable

getAreaTable()

Returns a key(area name)-value(area id) table with all known areas and their IDs. There is an area with the name of and an ID of 0 included in it, you should ignore that.

Example

<lua> -- example function that returns the area ID for a given area

function findAreaID(areaname)

 local list = getAreaTable()

 -- iterate over the list of areas, matching them with substring match. 
 -- if we get match a single area, then return it's ID, otherwise return
 -- 'false' and a message that there are than one are matches
 local returnid, fullareaname
 for area, id in pairs(list) do
   if area:find(areaname, 1, true) then
     if returnid then return false, "more than one area matches" end
     returnid = id; fullareaname = area
   end
 end
 
 return returnid, fullareaname

end

-- sample use: local id, msg = findAreaID("blahblah") if id then

 echo("Found a matching ID: " .. id")

elseif not id and msg then

 echo("ID not found; " .. msg)

else

 echo("No areas matched the query.")

end </lua>

getCustomEnvColorTable

envcolors = getCustomEnvColorTable()

Returns a table with customized environments, where the key is the environment ID and the value is a indexed table of rgb values.

Example

<lua> {

 envid1 = {r,g,b},
 envid2 = {r,g,b}

} </lua>

getMapLabel

labelinfo = getMapLabels(areaID, labelID)

Returns a key-value table describing that particular label in an area. Keys it contains are the X, Y, Z coordinates, Height and Width, and the Text it contains. If the label is an image label, then Text will be set to the no text string.

Example

<lua> lua getMapLabels(1658987) table {

 1: 'no text'
 0: 'test'

}

lua getMapLabel(1658987, 0) table {

 'Y': -2
 'X': -8
 'Z': 11
 'Height': 3.9669418334961
 'Text': 'test'
 'Width': 8.6776866912842

}

lua getMapLabel(1658987, 1) table {

 'Y': 8
 'X': -15
 'Z': 11
 'Height': 7.2520666122437
 'Text': 'no text'
 'Width': 11.21900844574

}

</lua>

getMapLabels

arealabels = getMapLabels(areaID)

Returns an indexed table (that starts indexing from 0) of all of the labels in the area, plus their label text. You can use the label id to deleteMapLabel() it.

Example

<lua> display(getMapLabels(43)) table {

 0: 
 1: 'Svorai's grove'

}

deleteMapLabel(43, 0) display(getMapLabels(43)) table {

 1: 'Svorai's grove'

} </lua>

getModulePriority

priority = getModulePriority(module name)

Returns the priority of a module as an integer. This determines the order modules will be loaded in - default is 0. Useful if you have a module that depends on another module being loaded first, for example.

getPath

getPath(roomID from, roomID to)

Returns a boolean true/false if a path between two room IDs is possible. If it is, the global speedWalkPath table is set to all of the directions that have to be taken to get there, and the global speedWalkDir table is set to all of the roomIDs you'll encounter on the way.

Example

<lua> -- check if we can go to a room - if yes, go to it if getPath(34,155) then

 gotoRoom(155)

else

 echo("\nCan't go there!")

end </lua>

getRoomArea

areaID = getRoomArea(roomID)

Returns the area ID of a given room ID. To get the area name, you can check the area ID against the data given by getAreaTable() function, or use the getRoomAreaName() function.

Note: If the room ID does not exist, this function will raise an error.

Example

<lua> display("Area ID of room #100 is: "..getRoomArea(100))

display("Area name for room #100 is: "..getRoomAreaName(getRoomArea(100))) </lua>

getRoomAreaName

areaname = getRoomAreaName(areaID)

Returns the area name for a given area id.

Example

<lua> echo(string.format("room id #455 is in %s.", getRoomAreaName(getRoomArea(455)))) </lua>

getRoomCoordinates

x,y,z = getRoomCoordinates(room ID)

Returns the room coordinates of the given room ID.

Example

<lua> local x,y,z = getRoomCoordinates(roomID) echo("Room Coordinates for "..roomID..":") echo("\n X:"..x) echo("\n Y:"..y) echo("\n Z:"..z) </lua>

getRoomEnv

envID = getRoomEnv(roomID)

Returns the environment ID of a room. The mapper does not store environment names, so you'd need to keep track of which ID is what name yourself.

Example

<lua> funtion checkID(id)

 echo(strinf.format("The env ID of room #%d is %d.\n", id, getRoomEnv(id)))

end </lua>

getRoomExits

getRoomExits (roomID): Returns the currently known non-special exits for a room in an key-index form: exit = exitroomid, ie:

Example

<lua> table {

 'northwest': 80
 'east': 78

} </lua>

getRoomIDbyHash

roomID = getRoomIDbyHash(hash)

Returns a room ID that is associated with a given hash in the mapper. This is primarily for MUDs that make use of hashes instead of room IDs (like Avalon.de MUD). -1 is returned if no room ID matches the hash.

Example

<lua> -- example taken from http://forums.mudlet.org/viewtopic.php?f=13&t=2177 _id1 = getRoomIDbyHash( "5dfe55b0c8d769e865fd85ba63127fbc" ); if _id1 == -1 then

 _id1 = createRoomID()
 setRoomIDbyHash( _id1, "5dfe55b0c8d769e865fd85ba63127fbc" )
 addRoom( _id )
 setRoomCoordinates( _id1, 0, 0, -1 )

end </lua>

getRoomName

roomName = getRoomName(roomID)

Returns the room name for a given room id.

Example

<lua> echo(string.format("The name of the room id #455 is %s.", getRoomname(455)) </lua>

getRooms

rooms = getRooms()

Returns the list of all rooms in the map in an area in roomid - room name format.

Example

<lua> -- simple, raw viewer for rooms in an area display(getRooms()) </lua>

getRoomsByPosition

getRoomsByPosition(areaID, x,y,z)

Returns an indexed table of all rooms at the given coordinates in the given area, or an empty one if there are none. This function can be useful for checking if a room exists at certain coordinates, or whenever you have rooms overlapping.

Example

<lua> -- sample script to determine a room nearby, given a relative direction from the current room local otherroom if matches[2] == "" then

 local w = matches[3]
 local ox, oy, oz, x,y,z = getRoomCoordinates(mmp.currentroom)
 local has = table.contains
 if has({"west", "left", "w", "l"}, w) then
   x = (x or ox) - 1; y = (y or oy); z = (z or oz)
 elseif has({"east", "right", "e", "r"}, w) then
   x = (x or ox) + 1; y = (y or oy); z = (z or oz)
 elseif has({"north", "top", "n", "t"}, w) then
   x = (x or ox); y = (y or oy) + 1; z = (z or oz)
 elseif has({"south", "bottom", "s", "b"}, w) then
   x = (x or ox); y = (y or oy) - 1; z = (z or oz)
 elseif has({"northwest", "topleft", "nw", "tl"}, w) then
   x = (x or ox) - 1; y = (y or oy) + 1; z = (z or oz)
 elseif has({"northeast", "topright", "ne", "tr"}, w) then
   x = (x or ox) + 1; y = (y or oy) + 1; z = (z or oz)
 elseif has({"southeast", "bottomright", "se", "br"}, w) then
   x = (x or ox) + 1; y = (y or oy) - 1; z = (z or oz)
 elseif has({"southwest", "bottomleft", "sw", "bl"}, w) then
   x = (x or ox) - 1; y = (y or oy) - 1; z = (z or oz)
 elseif has({"up", "u"}, w) then
   x = (x or ox); y = (y or oy); z = (z or oz) + 1
 elseif has({"down", "d"}, w) then
   x = (x or ox); y = (y or oy); z = (z or oz) - 1
 end

 local carea = getRoomArea(mmp.currentroom)
 if not carea then mmp.echo("Don't know what area are we in.") return end

 otherroom = select(2, next(getRoomsByPosition(carea,x,y,z)))

 if not otherroom then
   mmp.echo("There isn't a room to the "..w.." that I see - try with an exact room id.") return
 else
   mmp.echo("The room "..w.." of us has an ID of "..otherroom)
 end

</lua>

getRoomUserData

data = getRoomUserData(roomID, key (as a string))

Returns the user data stored at a given room with a given key, or "" if none is stored. Use setRoomUserData() function for setting the user data.

Example

<lua> display(getRoomUserData(341, "visitcount")) </lua>

getRoomWeight

room weight = getRoomWeight(roomID)

Returns the weight of a room. By default, all new rooms have a weight of 1.

getSpecialExits

exits = getSpecialExits(roomID)

Returns a roomid - command table of all special exits in the room. If there are no special exits in the room, the table returned will be empty.

Example

<lua> getSpecialExits(1337)

-- results in: --[[ table {

 12106: 'faiglom nexus'

} ]] </lua>

getSpecialExitsSwap

exits = getSpecialExitsSwap(roomID)

Very similar to getSpecialExits() function, but returns the rooms in the command - roomid style.

gotoRoom

gotoRoom (roomID): Speedwalks you to the given room from your current room if it is able and knows the way. You must turn the map on for this to work, else it will return "(mapper): Don't know how to get there from here :(".

hasExitLock

status = hasExitLock(roomID, direction)

Returns true or false depending on whenever a given exit leading out from a room is locked. direction right now is a number that corresponds to the direction:

 exitmap = {
   n = 1,
   north = 1,
   ne = 2,
   northeast = 2,
   nw = 3,
   northwest = 3,
   e = 4,
   east = 4,
   w = 5,
   west = 5,
   s = 6,
   south = 6,
   se = 7,
   southeast = 7,
   sw = 8,
   southwest = 8,
   u = 9,
   up = 9,
   d = 10,
   down = 10,
   ["in"] = 11,
   out = 12
 }

Example

<lua> -- check if the east exit of room 1201 is locked display(hasExitLock(1201, 4)) </lua>

hasSpecialExitLock

status = hasSpecialExitLock(from roomID, to roomID, command)

Returns true or false depending on whenever a given exit leading out from a room is locked. command is the action to take to get through the gate.

<lua> -- lock a special exit from 17463 to 7814 that uses the 'enter feather' command lockSpecialExit(17463, 7814, 'enter feather', true)

-- see if it is locked: it will say 'true', it is display(hasSpecialExitLock(17463, 7814, 'enter feather')) </lua>

highlightRoom

highlightRoom( id, r1,g1,b1,r2,g2,b2, radius, alpha1, alpha2)

Highlights a room with the given color, which will override it's environment color. If you use two different colors, then there'll be a shading from the center going outwards that changes into the other color. highlightRadius is the radius for the highlight circle - if you don't want rooms beside each other to over lap, use 1 as the radius. alphaColor1 and alphaColor2 are transparency values from 0 (completely transparent) to 255 (not transparent at all).

loadMap

boolean = loadMap(file location)

Loads the map file from a given location. The map file must be in Mudlet's format (not XML or any other) - saved with saveMap().

Returns a boolean for whenever the loading succeeded. Note that the mapper must be open, or this will fail.

lockExit

lockExit(roomID, direction, lock = true/false)

Locks a given exit from a room (which means that unless all exits in the incoming room are locked, it'll still be accessible). Direction at the moment is only set as a number, and here's a listing of them:

 exitmap = {
   n = 1,
   north = 1,
   ne = 2,
   northeast = 2,
   nw = 3,
   northwest = 3,
   e = 4,
   east = 4,
   w = 5,
   west = 5,
   s = 6,
   south = 6,
   se = 7,
   southeast = 7,
   sw = 8,
   southwest = 8,
   u = 9,
   up = 9,
   d = 10,
   down = 10,
   ["in"] = 11,
   out = 12
 }

Example

<lua> -- lock the east exit of room 1201 so we never path through it lockExit(1201, 4, true) </lua>

lockRoom

lockRoom (roomID, lock = true/false)

Locks a given room id from future speed walks (thus the mapper will never path through that room).

lockSpecialExit

lockSpecialExit (from roomID, to roomID, special exit command, lock = true/false)

Locks a given special exit, leading from one specific room to another that uses a certain command from future speed walks (thus the mapper will never path through that special exit).

Example

<lua> lockSpecialExit(1,2,'enter gate', true) -- locks the special exit that does 'enter gate' to get from room 1 to room 2 lockSpecialExit(1,2,'enter gate', false) -- unlocks the said exit </lua>

roomExists

roomExists(roomID)

Returns a boolean true/false depending if the room with that ID exists (is created) or not.

roomLocked

locked = roomLocked(roomID)

Returns true or false whenever a given room is locked.

saveMap

saveMap(location)

Saves the map to a given location, and returns true on success. The location folder needs to be already created for save to work.

searchRoom

searchRoom (room name)

Searches for rooms that match (by case-insensitive, substring match) the given room name. It returns a key-value table in form of roomid = roomname, like so:

Example

<lua> display(searchRoom("master"))

--[[ would result in: table {

 17463: 'in the branches of the Master Ravenwood'
 3652: 'master bedroom'
 10361: 'Hall of Cultural Masterpieces'
 6324: 'Exhibit of the Techniques of the Master Artisans'
 5340: 'office of the Guildmaster'
 (...)
 2004: 'office of the guildmaster'
 14457: 'the Master Gear'
 1337: 'before the Master Ravenwood Tree'

} ]]</lua>

If no rooms are found, then an empty table is returned.

setAreaName

setAreaName(areaID, newName)

Renames an existing area to the new name.

Example

<lua> setAreaName(2, "My city") </lua>

setCustomEnvColor

setCustomEnvColor(environmentID, r,g,b,a)

Creates, or overrides an already created custom color definition for a given environment ID. Note that this will not work on the default environment colors - those are adjustable by the user in the preferences. You can however create your own environment and use a custom color definition for it.

Example

<lua> setRoomEnv(571, 200) -- change the room's environment ID to something arbitrary, like 200 local r,g,b = unpack(color_table.blue) setCustomEnvColor(200, r,g,b, 255) -- set the color of environmentID 200 to blue </lua>

setExit

setExit(from roomID, to roomID, direction)

Creates a one-way exit from one room to another using a standard direction - which can be either one of n, ne, nw, e, w, s, se, sw, u, d, in, out, or a number which represents a direction.

Returns false if the exit creation didn't work.

Example

<lua> -- alias pattern: ^exit (\d+) (\w+)$

if setExit(mmp.currentroom, tonumber(matches[2]),matches[3]) then echo("\nExit set to room:"..matches[2]..", Direction:"..string.upper(matches[3])) centerview(mmp.currentroom) else mmp.echo("Failed to set the exit.") end </lua>

This function can also delete exits from a room if you use it like so: setExit(from roomID, -1, direction)

Which will delete an outgoing exit in the specified direction from a room.

<lua> -- locate the room on the other end, so we can unlink it from there as well if necessary local otherroom if getRoomExits(getRoomExits(mmp.currentroom)[dir])[mmp.ranytolong(dir)] then

 otherroom = getRoomExits(mmp.currentroom)[dir]

end

if setExit(mmp.currentroom, -1, dir) then

 if otherroom then
   if setExit(otherroom, -1, mmp.ranytolong(dir)) then
     mmp.echo(string.format("Deleted the %s exit from %s (%d).",
       dir, getRoomName(mmp.currentroom), mmp.currentroom))
    else mmp.echo("Couldn't delete the incoming exit.") end
 else
   mmp.echo(string.format("Deleted the one-way %s exit from %s (%d).",
     dir, getRoomName(mmp.currentroom), mmp.currentroom))
 end

else

 mmp.echo("Couldn't delete the outgoing exit.")

end </lua>

You can use these numbers for setting the directions as well:

<lua> exitmap = {

 n = 1,
 north = 1,
 ne = 2,
 northeast = 2,
 nw = 3,
 northwest = 3,
 e = 4,
 east = 4,
 w = 5,
 west = 5,
 s = 6,
 south = 6,
 se = 7,
 southeast = 7,
 sw = 8,
 southwest = 8,
 u = 9,
 up = 9,
 d = 10,
 down = 10,
 ["in"] = 11,
 out = 12

}</lua>

setGridMode

setGridMode(area, true/false)

Enables grid/wilderness view mode for an area - this will cause the rooms to lose their visible exit connections, like you'd see on compressed ASCII maps, both in 2D and 3D view mode.

Example

<lua> setGridMode(55,true) -- set area with ID 55 to be in grid mode </lua>

setModulePriority

setModulePriority(module name, priority #)

Sets the module priority on a given module as a number - the module priority determines the order modules are loaded in, which can be helpful if you have ones dependent on each other. This can also be set from the module manager window.

setRoomArea

setRoomArea(roomID, newAreaID)

Assigns the given room to a new area. This will have the room be visually moved into the area as well.

setRoomChar

setRoomChar(roomID, character)

Designed for an area in grid mode, this will set a single character to be on a room. You can use "_" to clear it.

Example

<lua> setRoomChar(431, "#")

setRoomChar(123. "$") </lua>

setRoomCoordinates

setRoomCoordinates(roomID, x, y, z)

Sets the given room ID to be at the following coordinates visually on the map, where z is the up/down level.

Note: 0,0,0 is the center of the map.

Example

<lua> -- alias pattern: ^set rc (-?\d+) (-?\d+) (-?\d+)$ local x,y,z = getRoomCoordinates(previousRoomID) local dir = matches[2]

if dir == "n" then

 y = y+1

elseif dir == "ne" then

 y = y+1
 x = x+1

elseif dir == "e" then

 x = x+1

elseif dir == "se" then

 y = y-1
 x = x+1

elseif dir == "s" then

 y = y-1

elseif dir == "sw" then

 y = y-1
 x = x-1

elseif dir == "w" then

 x = x-1

elseif dir == "nw" then

 y = y+1
 x = x-1

elseif dir == "u" or dir == "up" then

 z = z+1

elseif dir == "down" then

 z = z-1

end setRoomCoordinates(roomID,x,y,z) centerview(roomID) </lua>

You can make them relative as well:

<lua> -- alias pattern: ^src (\w+)$

local x,y,z = getRoomCoordinates(previousRoomID) local dir = matches[2]

if dir == "n" then

 y = y+1

elseif dir == "ne" then

 y = y+1
 x = x+1

elseif dir == "e" then

 x = x+1

elseif dir == "se" then

 y = y-1
 x = x+1

elseif dir == "s" then

 y = y-1

elseif dir == "sw" then

 y = y-1
 x = x-1

elseif dir == "w" then

 x = x-1

elseif dir == "nw" then

 y = y+1
 x = x-1

elseif dir == "u" or dir == "up" then

 z = z+1

elseif dir == "down" then

 z = z-1

end setRoomCoordinates(roomID,x,y,z) centerview(roomID) </lua>

setRoomEnv

setRoomEnv(roomID, newEnvID)

Sets the given room to a new environment ID. You don't have to use any functions to create it - can just set it right away.

Example

<lua> setRoomEnv(551, 34) -- set room with the ID of 551 to the environment ID 34 </lua>

setRoomIDbyHash

setRoomIDbyHash(roomID, hash)

Sets the hash to be associated with the given roomID. See also getRoomIDbyHash().

setRoomName

setRoomName(roomID, newName)

Renames an existing room to a new name.

Example

<lua> setRoomName(534, "That evil room I shouldn't visit again.") lockRoom(534, true) -- and lock it just to be safe </lua>

setRoomUserData

setRoomUserData(roomID, key (as a string), value (as a string))

Stores information about a room under a given key. Similar to Lua's key-value tables, except only strings may be used here. One advantage of using userdata is that it's stored within the map file itself - so sharing the map with someone else will pass on the user data. You can have as many keys as you'd like.

Returns true if successfully set.

setRoomWeight

setRoomWeight(roomID, weight)

Sets a weight to the given roomID. By default, all rooms have a weight of 0 - the higher the weight is, the more likely the room is to be avoided for pathfinding. For example, if travelling across water rooms takes more time than land ones - then you'd want to assign a weight to all water rooms, so they'd be avoided if there are possible land pathways.

To completely avoid a room, make use of lockRoom().

speedwalk

speedwalk(dirString, backwards, delay)

A speedwalking function will work on cardinal+ordinal directions (n, ne, e, etc.) as well as u (for up), d (for down), in and out. It can be called to execute all directions directly after each other, without delay, or with a custom delay, depending on how fast your mud allows you to walk. It can also be called with a switch to make the function reverse the whole path and lead you backwards.

Call the function by doing: speedwalk("YourDirectionsString", true/false, delaytime)

The delaytime parameter will set a delay between each move (set it to 0.5 if you want the script to move every half second, for instance). It is optional: If you don't indicate it, the script will send all direction commands right after each other. (If you want to indicate a delay, you -have- explicitly indicate true or false for the reverse flag.)

The "YourDirectionsString" contains your list of directions and steps (e.g.: "2n, 3w, u, 5ne"). Numbers indicate the number of steps you want it to walk in the direction specified after it. The directions must be separated by anything other than a letter that can appear in a direction itself. (I.e. you can separate with a comma, spaces, the letter x, etc. and any such combinations, but you cannot separate by the letter "e", or write two directions right next to each other with nothing in-between, such as "wn". If you write a number before every direction, you don't need any further separator. E.g. it's perfectly acceptable to write "3w1ne2e".) The function is not case-sensitive.

If your Mud only has cardinal directions (n,e,s,w and possibly u,d) and you wish to be able to write directions right next to each other like "enu2s3wdu", you'll have to change the pattern slightly. (See the link at the beginning of my post for something like that.)

Likewise, if your Mud has any other directions than n, ne, e, se, s, sw, w, nw, u, d, in, out, the function must be adapted to that.

Example

<lua> speedwalk("16d1se1u") -- Will walk 16 times down, once southeast, once up. All in immediate succession.

speedwalk("2ne,3e,2n,e") -- Will walk twice northeast, thrice east, twice north, once east. All in immediate succession.

speedwalk("IN N 3W 2U W", false, 0.5) -- Will walk in, north, thrice west, twice up, west, with half a second delay between every move.

speedwalk("5sw - 3s - 2n - w", true) -- Will walk backwards: east, twice south, thrice, north, five times northeast. All in immediate succession.

speedwalk("3w, 2ne, w, u", true, 1.25) -- Will walk backwards: down, east, twice southwest, thrice east, with 1.25 seconds delay between every move. </lua>

Note: The probably most logical usage of this would be to put it in an alias. For example, have the pattern ^/(.+)$ execute: speedwalk(matches[2], false, 0.7) And have ^//(.+)$ execute: speedwalk(matches[2], true, 0.7) Or make aliases like: ^banktohome$ to execute <lua>speedwalk("2ne,e,ne,e,3u,in", true, 0.5)</lua>
