createLabel

createLabel(name, Xpos, Ypos, width, height, fillBackground)

Creates a highly manipulable overlay which can take some css and html code for text formatting. Labels are clickable, and as such can be used as a sort of button. Labels are meant for small variable or prompt displays, messages, images, and the like. You should not use them for larger text displays or things which will be updated rapidly and in high volume, as they are much slower than miniconsoles.

Returns true or false.

createMiniConsole("sys",WindowWidth-650,0,650,300) setBackgroundColor("sys",85,55,0,255) setMiniConsoleFontSize("sys", 8) -- wrap lines in window "sys" at 40 characters per line setWindowWrap("sys", 40) -- set default font colors and font style for window "sys" setTextFormat("sys",0,35,255,50,50,50,0,0,0)

echo("sys","Hello world!") </lua>

deleteLine

deleteLine()

Deletes the current line under the user cursor. This is a high speed gagging tool and is very good at this task, but is only meant to be use when a line should be omitted entirely in the output. If you echo() to that line it will not be shown, and lines deleted with deleteLine() are simply no longer rendered. For replacing text, replace() is the proper option.

See Also: replace, wrapLine

No Parameters

Example

<lua> --This example creates a temporary line trigger to test if the next line is a prompt, and if so gags it entirely. --This can be useful for keeping a pile of prompts from forming if you're gagging chat channels in the main window --Note: isPrompt() only works on servers which send a GA signal with their prompt. tempLineTrigger(1, 1, if isPrompt() then deleteLine() end) </lua>

deselect

deselect(name)

This is used to clear the current selection (to no longer have anything selected). Should be used after changing the formatting of text, to keep from accidentally changing the text again later with another formatting call.

Parameters

• name:

The name of the buffer/miniConsole to stop having anything selected in. This is an optional argument, if name is not provided the main window will have its selection cleared. Passed as a string.

Example

<lua> --This will change the background on an entire line in the main window to red, and then properly clear the selection to keep further --changes from effecting this line as well. selectCurrentLine() bg("red") deselect() </lua>

fg

fg(colorName)

If used on a selection, sets the foreground color to colorName - otherwise, it will set the color of the next text-inserting calls (echo(), insertText, echoLink(), and others)

See Also: bg, setBgColor

Parameters

• colorName:

The name of the color to set the foreground to - list of possible names:

Examples

<lua> --This would change the color of the text on the current line to green selectCurrentLine() fg("green") resetFormat()

--This will echo red, green, blue in their respective colors fg("red") echo("red ") fg("green") echo("green ") fg("blue") echo("blue ") resetFormat() </lua>

getMainWindowSize

getMainWindowSize()

Returns two numbers, the width and height in pixels.

No Parameters

Example

<lua> --this will get the size of your main mudlet window and save them --into the variables mainHeight and mainWidth mainWidth, mainHeight = getMainWindowSize() </lua>

resetFormat

resetFormat()

Resets the colour/bold/italics formatting. Always use this function when done adjusting formatting, so make sure what you've set doesn't 'bleed' onto other triggers/aliases.

Example

<lua> -- select and set the 'Tommy' to red in the line selectString("Tommy", 1) fg("red")

-- now reset the formatting, so our echo isn't red resetFormat() echo(" Hi Tommy!")

-- another example: just highlighting some words for _, word in ipairs{"he", "she", "her", "their"} do

 if selectString(word, 1) ~= -1 then
   bg("blue")
 end

end resetFormat() </lua>

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 http://forums.mudlet.org/viewforum.php?f=13[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:

mudlet = mudlet or {}; mudlet.mapper_script = true

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:

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'
  19067: 'the master's gallery'
  21546: 'the Grand Master's Chambers'
  6592: 'hall before the Master Chambers'
  4395: 'customs Office and Harbourmaster's'
  18978: 'the master's salon'
  1622: 'before the office of the harbourmaster'
  18869: 'Master's gallery and reception suite'
  14456: 'north of the Master Gear'
  14624: 'beastmaster's hangout'
  9078: 'chambers of the Master of the Bloodhunt'
  6593: 'Master Quettle's Chambers'
  10210: 'the chambers of Master Blasterson'
  14465: 'south of the Master Gear'

  2004: 'office of the guildmaster'
  14457: 'the Master Gear'
  1337: 'before the Master Ravenwood Tree'
}
]]

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

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.

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

centerview

centerview (room number)

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.

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 :(".

getRoomExits

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

table {
  'northwest': 80
  'east': 78
}

addRoom

addRoom(roomID)

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

<lua> local newroomid = createRoomID() addRoom(newroomid) </lua>

lockRoom

lockRoom (roomID, lock = true/false)

Locks a given room id from future speed walks (-> never enter that room).

lockRoom(1, true) -- locks a room if from being walked through when speedwalking.
lockRoom(1, false) -- unlocks the room, adding it back to possible rooms that can be walked through.

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.

setRoomWeight(1532, 1) -- avoid using this room if possible, but don't completely ignore it

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

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 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

getAreaRooms

getAreaRooms(area id)

Returns an indexed table with all rooms IDs for a given area ID (room IDs are values)

-- 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

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.

-- 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

roomExists

roomExists(roomID)

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

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.

Returns false if the exit creation didn't work.

-- 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

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.

-- 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

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.

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

-- alias pattern: ^set rc (-?\d+) (-?\d+) (-?\d+)$
local x,y,z = getRoomCoordinates(previousRoomID)
