WA to display caster's name

[Angrybathtub]

So I've been trying to get a weakaura to display the caster's name that gave me a specific buff. For example, when "John" gives me a Hand of Sacrifice, I want his name to show up under the icon for Hand of Sacrifice.

I know I can manually hardcode every potential healers name for the external, but I'm sure theres a way to do it with a LUA script.

function(event, timestamp, message, hideCaster, sourceGUID, sourceName, sourceFlags, sourceRaidFlags, destGUID, destName, destFlags, destRaidFlags, ...)  
    if message == "SPELL_CAST_SUCCESS" then
        local spellId, spellName, spellSchool = ...
        if spellName == "Hand of Sacrifice" then   
            name = sourceName
            return true
        end
    end
end

All I'm getting is the name of the ability, not the name of the person giving me the buff.

Any idea?

I would start up there. Instead of looking at who cast the spell, look at the buff attached to your character and figure out it's source.

getting the source of the buff gives you the unit id, from there you need to get the player name.

Did you add this to the custom name function and set %n as the display text?

function()
    return name
end
