Helpful Mudlet snippets!

Hey there!

I figure this might be a good addition for people getting their feet wet. The point is to post a snippet of code that proves helpful to others. Be it alias, trigger, script, etc. Please state whether it's for mudlet or Nexus or otherwise!

I will kick us off.

Mudlet:

Script:

function isClass(className)
	if string.lower(gmcp.Char.Status.class):match(string.lower(className)) == string.lower(className) then
		return true
	else
		return false
	end
end

Usage:

if isClass("runewarden") then
    --stuff!
else
    --things!
end

if isClass("dragon") then
    --stuff!
else
    --things!
end

- Easy, non long way to tell what class you are.

Love the idea.

A few tips to shorten that one, you can call lower() like you did match(), use find() instead of match(), use type() to check if it returned a number (it returns nil if it doesn't find it) instead of using if statements, then you end up with:

function isClass(className)
  return type(gmcp.Char.Status.class:lower():find(className:lower())) == "number"
end

end


didn't think you could chain those! awesome.

One of my own, something I made goofing off, how to check what health a certain level/con/bracelet combination will give. Mudlet.

  gethealth = function (arg)
    local level = arg.level
    local olevel = 0

    if level > 100 then
      olevel = level - 100
      level = 100
    end

    local con = arg.con

    local bracelets = arg.bracelets or 0

    if level < 1 or level >= 200 then
      return "Invalid character level. Please choose a character level between 1 and 199."
    elseif bracelets < 0 or bracelets > 3 then
      return "Invalid bracelet level. Please choose a bracelet level between 0 and 3."
    else
      return math.floor ((300+level*(3*con+4)+olevel*(3*con-16))*(1+bracelets*0.05))
    end -- if
  end, -- func

You call it (note the curly braces) like: gethealth {level=101,con=23,bracelets=2}

for i,v in pairs(gmcp.Room.Info.exits) do

if not roomexits then

roomexits = string.upper(i)

else

Here's a lua iterator that runs through a table's keys alphabetically. Non-client-specific as long as it runs lua.

sortedpairs = function (tbl)
  local i = 0
  local tmp = {}
  for n in pairs (tbl) do table.insert (tmp, n) end
  table.sort (tmp)
  return function ()
    i = i + 1
    if tmp[i] ~= nil then return tmp[i], tbl[tmp[i]] end
  end -- func
end -- func

As an example...

Given table: t = {b=true,a=true,c=true}
You use it like so: for k, v in sortedpairs (t) do print (k, v) end
And the result is:

a true

b true

c true

I use this a lot when displaying output, like my rift.

Does anyone have something for wielding?

Here is a target herb/mineral highlight that I use:

function colourHerbs(herb)
-- cecho(herb)
if (herb == "aurum flake") or (herb == "piece of kelp") then
cecho("\n<white:green>[ KELP ][ KELP ]\n")
targeat:cecho("<white:green>[ KELP ]\n")
elseif (herb == "lobelia seed") or (herb == "argentum flake") then
cecho("\n<white:orange>[ LOBELIA ][ LOBELIA ]\n")
targeat:cecho("<white:orange>[ LOBELIA ]\n")
elseif (herb == "kola nut") or (herb == "quartz grain") then
cecho("\n<white:dark_orchid>[ KOLA ][ KOLA ]\n")
targeat:cecho("<white:dark_orchid>[ KOLA ]\n")
elseif (herb == "cuprum flake") or (herb == "bellwort flower") then
cecho("\n<white:gold>[ Bellwort ][ Bellwort ]\n")
targeat:cecho("<white:gold>[ Bellwort ]\n")
elseif (herb == "hawthorn berry") or (herb == "calamine crystal") then
cecho("\n<white:brown>[ Hawthorn ][ Hawthorn ]\n")
targeat:cecho("<white:brown>[ Hawthorn ]\n")
elseif (herb == "stannum flake") or (herb == "prickly ash bark") then
cecho("\n<white:purple>[ ASH ][ ASH ]\n")
targeat:cecho("<white:purple>[ ASH ]\n")
elseif (herb == "ginseng root") or (herb == "ferrum flake") then
cecho("\n<white:blue>[ GINSENG ][ GINSENG ]\n")
targeat:cecho("<white:blue>[ GINSENG ]\n")
elseif (herb == "bloodroot leaf") or (herb == "magnesium chip") then
cecho("\n<white:red>[ BROOT ][ BROOT ]\n")
targeat:cecho("<white:red>[ BROOT ]\n")
elseif (herb == "goldenseal root") or (herb == "plumbum flake") then
cecho("\n<white:yellow>[ GSEAL ][ GSEAL ]\n")
targeat:cecho("<white:yellow>[ GSEAL ]\n")
end -- if
end -- colourHerbs
Called by a simple trigger for the eat line:
if matches[2] == target then
colourHerbs(matches[4])
end

Edit: You can definitely rewrite my code to be better, but I wrote it years ago, and it works =D

@Medi If you don't want to use containers (scabbards, belthooks, etc), you don't need a script for wielding (except possibly in retardation?). WIELD <left> <right> will handle unwielding items already in your hands for you. If you do want to use containers, it gets a lot more complicated quite quickly.

You could massively reduce that hypnosis script, make it easier to add additional hypnosis stacks, and make it more user friendly, by doing something like this:

-- Script

hypnoAffs = {
	{
		"aff1", "aff2", "aff3", "aff4", "aff5"
	}, -- 1
	{
		"aff2", "aff6", "aff7"
	}, -- 2,
	-- etc.
}

function hypnoStack()
	local list = hypnoAffs[hyp]
	if list and list[hypnoStep] then
		sendAll("setalias hyp suggest " .. target .. " " .. list[hypnoStep], "queue add eqbal hyp", false)
	else
		-- message indicating end of stack or invalid list
	end
end

-- Alias

^hyp(\d+)$
-- if we're not a Serpent, do nothing
if gmcp.Char.Status.class ~= "Serpent" then return end
hypnoStep = 1
hyp = tonumber(matches[2])
local affs = hypnoAffs[hyp]
if affs then
	cecho("\n[Hypnotising " ..target.. " with " .. string.concat(affs, ", ") .. ".]")
	send("hypnotise " ..target)
else
	-- some kind of error message indicating you've tried to use a list that doesn't exist
end

-- Alias
^hyp$
hypnoStack()

-- Trigger
^You issue the suggestion, concealing it deep within (\w+)'s mind\.$

hypnoStep = hypnoStep+1
deleteFull()
cecho("\n[Suggest Succeeded]")

Adding a stack is as simple as adding a new entry into the hypnoAffs table, and it's just a list of affs itself, not the full commands, so it saves on typing (bonus: you can display exactly what it's going to suggest when picking the stack). Added some comments where you'd inform the user that they've tried to do something that won't work, like use a hypno stack they haven't defined or tried to suggest when there's no more suggestions.

Convert a number into a comma-separated string (ex: 1500000 to 1,500,000).

function comma (num)
   local subs
   while true do
      num, subs = tostring(num):gsub("^(-?%d+)(%d%d%d)", "%1,%2")
      if subs == 0 then break end
   end
   return num
end

Howdy, Stranger!
