The Golden Belt of the Enlightened

Here's an easy way to make use of your Belt of the Enlightened with GMCP, Mudlet's Mapper, and the IRE Mapping Script in under 5 minutes. First, we'll map the chamber and second, we'll create the script. Once you're up and running, the mapper will begin to check all rooms to see if they're outdoors, and if so remember them as a location where you can use your belt. If you've not yet enabled GMCP, it can be turned on by clicking 'Settings' and selecting 'Enable GMCP' on the first screen, second from the bottom.

First, touch your belt to teleport to the chamber. To map the room, enter the following commands in order from Mudlet's main command line:
mc on
rlc v19627 0 0 0
area add Limbo
room area Limbo
rlk 19343 se one
rlk 19514 nw one
rlk 19222 up one
rlk 19666 sw one
rlk 19527 ne one
rlk 11401 down one
rlk 19693 north one
mc off

Second, we setup the script! We'll create a script group, I called mine 'MapHax'. I didn't place it inside of 'mudlet-mapper' to avoid any issues when the IRE Mapping Script updates. Open up a plain text editor (Notepad, Gedit, etc.) and save a blank file inside your mudlet home directory called 'maphax'. If you don't know where your mudlet home directory is, from the command line run 'lua echo(getMudletHomeDir())'. Inside the group, paste the following script:

maphaxloc = getMudletHomeDir().. "/maphax"
maphax = maphax or {beltlocked = {}}

function MapHax()
  loadMapHax()
end

function loadMapHax()
  if io.exists(maphaxloc) then table.load(maphaxloc, maphax) end
end

function saveMapHax()
  if io.exists(maphaxloc) then table.save(maphaxloc, maphax) end
end
Inside that group, we'll create a script item called 'The Belt of the Enlightened'. In the body of the script, copy and paste the following:
registerAnonymousEventHandler("gmcp.Room.Info", "checkBelt")

function checkBelt()
  local area = gmcp.Room.Info.area
	local outdoors = gmcp.Room.Info.details[2]
  if not table.contains(maphax.beltlocked, area) and outdoors == "outdoors" then
		local num = gmcp.Room.Info.num
    if not table.contains(getSpecialExits(num), "TOUCH ENLIGHTENED") then
      addSpecialExit(num, 19627, "TOUCH ENLIGHTENED")
  		echo("\n(Map Hax): Added use of the Golden Belt of the Enlightened from v".. num..".")
    end
  end
end

function beltLock(num, area)
  if not table.contains(maphax.beltlocked) then
	  table.insert(maphax.beltlocked, area)
		echo("\n(MapHax): Can't use the Golden Belt of the Enlightened, locking the area.")
	end

	for k, v in pairs(getAreaRooms(getRoomArea(num))) do
	  if table.contains(getSpecialExits(v), "TOUCH ENLIGHTENED") then
      removeSpecialExit(v, "TOUCH ENLIGHTENED")
    end
	end
end
