Mob Health tag on Svo Custom Prompt

At the end of this process, you will be able to use the @otgMH tag in Svo's custom prompt to display denizen health.

Firstly, you need to adjust the default prompt to use Achaea's internal custom prompt. Don't worry, this won't break Svo's custom prompt or defence tracking. Enter the following line into the command box of Mudlet when connected to Achaea:

CONFIG PROMPT CUSTOM *hh, *mm *b*d-*r-((*T))

-- NEW! Importable xml file: http://1drv.ms/1scGUXh

Create a trigger, call it something sensible like Grab mob health from prompt
Pattern (set to perl regex):
^(\d+)h, (\d+)m (\w+)-(?:\w+|-|)-\(\((\d+)\%\)\)-

Script:
mobHealthPct = matches[6] or matches[5]


This has now assigned the mob health percentage from the prompt to variable mobHealthPct

Create a new script, copy in the following functions (to just before the line ========= ):

mobHealthPct = mobHealthPct or 0 --sets up the variable, without this your prompt is blank until yout hit something

function promptMobHealth()

	local h = tonumber(mobHealthPct)
	mhc = "blanched_almond"

	if h == 0 then
		mhc = ""
		return mhc --this will hide the tag when the mob is killed
	elseif h < 5 then
		mhc = "red" --nearly dead
	elseif h < 25 then
		mhc = "orange_red" --grievously wounded
	elseif h < 50 then
		mhc = "dark_orange" --injured
	elseif h < 75 then
		mhc = "orange" --slightly injured
	end

	mhc = " <"..mhc..">("..h.."%)<reset>"

	return mhc

end

function clearMobHealth() --sets the mobHealthPct to 0 when the mob is killed
	if gmcp.Char.Items.Remove.location == "room" then
		if gmcp.Char.Items.Remove.item.id == gmcp.Char.Status.target then
			mobHealthPct = 0
			promptMobHealth()
		end
	end
end

function addPromptDef()
	svo.adddefinition("@otgMH", "promptMobHealth()")
end

registerAnonymousEventHandler("svo system loaded", "addPromptDef")
registerAnonymousEventHandler("gmcp.Char.Items.Remove", "clearMobHealth")

=========
Assuming you have a prompt trigger somewhere to fire updates, add in the line
promptMobHealth()

If not, create a new trigger, give it a name like "Fire on prompt" and enter the following:
Pattern (set to Lua function):
return isPrompt()

Script:
promptMobHealth()


Once all this is done, you need to register the custom prompt tag (only this time, it will be autoregisted when Svo next loads) by entering the following on the command line of Mudlet:
vlua addPromptDef()

You should now be able to use @otgMH in your Svo custom prompt.
