Help with a threat function issue please ?

[Caellian]

Allright so, here's a small threat function, working just fine but not exactly the way i want it to work.

caelPanels.UNIT_THREAT_SITUATION_UPDATE = function(self)
	local status = UnitThreatSituation("player", "target")
	for i = 1, 7 do
		local panel = panels[i]
		if panel then
			if (status and status > 0) then
				local r, g, b = GetThreatStatusColor(status)
				panel:SetBackdropBorderColor(r, g, b)
			else
				panel:SetBackdropBorderColor(0, 0, 0)
			end
		end
	end
end

As you can see local status = UnitThreatSituation("player", "target")

It will only show my threat toward my current target, but my goal was to have it change color if i have aggro from any mob, not just my target, let's take a quick example, i target a mob in a pack of 10 and start using Volley, and get aggro from one of the mob but not the one i'm targetting...

I've tried to do local status = UnitThreatSituation("player", unit) but that doesn't seems to work.

Any idea ?
