How to show target power only for worldboss level units

[Sauerkraut]

I was asked to add a power value to my target frames, however I personally don't feel that I want it all the time. Just for boss fights like LDW. I've tries to add it with the UnitClassification(unit) == "worldboss" but it doesn't seem to be working.

Does anyone have any input on how I might accomplish this? Or will I be stuck with values on every target.

	local ppval = lib.gen_fontstring(f, cfg.font, fontsize, "THINOUTLINE")
		if (UnitClassification(unit) == "worldboss") then
		ppval:SetPoint("RIGHT", f.Power, "RIGHT", 0, -12)
		ppval:SetJustifyH("RIGHT")
		else 
		ppval:ClearAllPoints()
	end
	
	if (UnitClassification(unit) == "worldboss") then
		f:Tag(ppval, "[karma:pp] [karma:power]")
	else
		f:Tag(ppval, "")
	end

You cannot do it that way. Because this is the spawn. Targets change all the time, setting the condition just in the target spawn is wrong. Instead move the condition to your power tags. Use the unit information in the tag to grab the unitlevel. If the target has level -1 it is a worldboss.

Ahh I hadn't thought of that Zork, Thanks.

Took me a while to figure it all out, but I got it working. Thanks for the push in the right direction Zork. I really appreciate it.

Here is the code stripped down.

oUF.Tags['karma:bosspp'] = function(u)
	if UnitLevel(u) < 0 then 
		local _, str = UnitPowerType(u)
		if str then
			return hex(pcolors.power[str] or {250/255,  75/255,  60/255})..SVal(UnitPower(u))
		end
	end
end
oUF.TagEvents['karma:bosspp'] = 'UNIT_POWER'
