Getting Percentages with Weakauras

[Quarla]

I'm not a coder or anything of the like and I'm pretty sure you need to know a bit of lua or something to get percentages to show up. I tried doing a search but the strings in the topic I found weren't working. Anyway, I'm trying to make a simple manabar that shows my percentage of mana rather than the big long number of the total mana my character has remaining.

Anyone have a simple way to achieve my goal with this addon?

Set one of the text displays to a custom function:

function()

 -- first let's get our current mana
 local current_mana = UnitPower("player", SPELL_POWER_MANA) 

 -- now we'll find out how much mana we could have if we were full
 local maximum_mana = UnitMaxPower("player", SPELL_POWER_MANA)
 
 -- current divided maximum equals percent, don't forget to multiply by 100.  Just like 8th grade math test scores!
 local percent_mana = ((current_mana / maximum_mana) * 100)

 -- now we just need to format that into a string with one decimal point and the percent symbol
 return string.format("%.1f%%", percent_mana)

end

You could string that into one line without all the comments and intermediate variables, but I think it's easier for a non programmer to read and understand what's going on when you see it this way.

Hmm, thanks so much for your help Evn but I added it to the custom function and nothing is showing up. I'll post the string in case I'm missing something that I just don't see.

Try this. It should work. If you want it to only show below a certain % mana simply set the fuction under the trigger.

Ahh. It won't work with bars just icons I guess. Well that's disappointing. Was trying to slide it into a sliver of a spot. lol Well thank you Killora. I'll figure out a way to make this work in my UI.
