Lua Code:
GameTooltip:HookScript("OnTooltipSetUnit", TooltipCallback)
function TooltipCallback(tooltip, ...)
local unitName, unitId = tooltip:GetUnit()
GameTooltip:AddLine(unitName)
end
The new line is not added. What is wrong? And what arguments OnTooltipSetUnit callback should have? I've a lot of different options ('self', 'self, tooltip', 'self, ...', 'tooltip, ...' and so on)...
