STUF Help - [perchp]

[Cerranos]

Currently I'm using Stuf UF... and was wondering how I could change the "[perchp]" text to include a decimal, such as 100.0% instead of just a whole number. This way, it'll make it easier to determine what specific health the target is at when it is around 0%; eg 0.6% or 0.2%, etc.

Any help is greatly appreciated. Thank you in advance!

Well, the [perchp] tag won't work for you.

However, StUF has the option for "Custom Lua Code" or "Custom Lua Script". Use that, and copy/paste this into the text box that pops up, and then click "Accept", and then click the box for "Frequent Updates" (necessary to see changes as they happen).

Code has been tested - shows "%100.0" at full HP, "%37.1" after I jumped from the FP in Thunder Bluff to the lowest plateau in TB.

Changing the number in the two instances of "%%%.1f" will change how many positions after the decimal point are shown - 1 for 1, 2 for 2, etc.

function(unit, cache, textframe)
  if UnitExists(unit) then
    local perchp = 100 * UnitHealth(unit)/UnitHealthMax(unit)
    return "%.1f%%",perchp
  else
    local perchp = 100 * UnitHealth("player")/UnitHealthMax("player")
    return "%.1f%%",perchp
  end
end

Awesome... just one quick question; the code puts the % symbol in front of the number - how would I get it to be behind the number?

See where there are three percent signs in a row in the code? Move two of them to after the f.

Very cool, Seerah!

I had a hunch that was it... but I entered 3 of the percentage symbols initially.

Thank you for the help!!

It seems to only work for my player frame... how would I get it to work for target, pet, group, etc? I tried replacing the "player" text with "target," but it shows -1.$

EDIT: Nvm... I was in config mode for Stuf. But I'm curious - this code should work for all unit frames that I apply it to, right? Regardless if it's a pet, target, target/target, the text should still have "player" referenced? (sorry, at work and haven't had a chance to test it)

StUF is a little goofy - that code is safe to use in any frame, the "player" reference in the second half is to deal with StUF's config mode.

StUF can fake stuff on it's own really well - if you're using the tags that StUF provides.

I'll go line by line through the code, so you can see what's going on.

function(unit, cache, textframe)
  if UnitExists(unit) then 
    local perchp = 100 * UnitHealth(unit)/UnitHealthMax(unit)
    return "%.1f%%",perchp
  else
    local perchp = 100 * UnitHealth("player")/UnitHealthMax("player")
    return "%.1f%%",perchp
  end
end

function(unit, cache, textframe)

function header required by StUF Custom Lua

if UnitExists(unit) then

if there's actually such a unit (target, party, etc) do the next chunk (in this case, the next 2 lines)

local perchp = 100 * UnitHealth(unit)/UnitHealthMax(unit)

make a local variable called "perchp", and set it equal to their current percentage of HP.

return "%.1f%%",perchp

tell StUF to show the current HP percentage, with 1 decimal place, and a % sign after it

else

refers to the 2nd line - if Unit does NOT exist, do the next chunk (next 2 lines)

local perchp = 100 * UnitHealth("player")/UnitHealthMax("player")

make that local variable perchp, set it to the player's health percentage (why? so StUF config mode doesn't bug out)

return "%.1f%%",perchp

return the player's health percentage, formatted the same as earlier

end

closes the If-Then-Else decision

end

closes the function

Awesome... got it to work. Thanks again!
