Addon working only against a certain class

[Glon]

Hi there,

I'm trying to make one of my addons (RangeDisplay) work only when the player I'm targetting is a warrior. I have very little experience with lua coding, and had no luck finding any thread on this so far. Is it at all possible? If so, is there a chance to add such a feature to an already written addon?

local _,classfile = UnitClass("target")
if classfile == "WARRIOR" then
-- your target is a warrior
end

Had some trouble implementing it, but eventually it works perfectly. Thank you very much, Fizzlemizz .
