Stuck on using table varibles

CrazyCactuaR · 10-20-13, 07:53 AM

Hi all and thanks for reading/helping.

Code:

local p="Player"
my = {
	Class = UnitClass(p),
	Level = UnitLevel(p),
	Spec = GetSpecialization(p),
}

local t="Target"
tar = {
	Class = UnitClass(t),
	Level = UnitLevel(t),
	Spec = GetSpecialization(t),
}

Using this code WoW will happily work if i do my.Class, my.Level or my.Spec. However doing tar.Class/tar.Level/tar.Spec all return nil even with a selected target. Manually using UnitClass(t) will also work.

So my question is since i have no idea why this doesnt work is why, and how do i solve it?

Thank you

This code runs at load time. At this time you dont have a target.
You need to react to an event and update this table when the event occurs.
"PLAYER_TARGET_CHANGED" is such an event.

Lua Code:

local f = CreateFrame("Frame")
local tar
f:RegisterEvent("PLAYER_TARGET_CHANGED")
f:SetScript("OnEvent", function(self, event)
local t="target"
tar = {
    Class = UnitClass(t),
    Level = UnitLevel(t),
    Spec = GetSpecialization(t),
}
end)

ah i see, I always thought it would work even if i had a target. Thank you for that

Also, you won't get your target's spec with GetSpezialisation(). You'll need to use GetInspectSpezialisation() for which you'll have to query an inspect on the target unit and wait for the INSPECT_READY event.
