How to tell Horde or Alliance?
 

This may have been asked before, but I tried finding it, and drew a blank...

What I'd like to know is what function to call to figure out if a character you play is Horde or Alliance. Basically, I'm saving skill information, but don't think it's very useful showing the skills for Alliance chars when playing a Horde char on the same server, so I'd like to differentiate between the two of them.

Assistance would be appreciated. :)

I think you have to make use of UnitRace("unit") and check for raceEN.

Check out http://www.wowwiki.com/API_UnitFactionGroup

Fun facts:

UnitFactionGroup("player") is available only after PLAYER_LOGIN, whereas
UnitRace("player") is always available.

So if you need to check your own faction at the beginning, you'd have to check:

local _,race = UnitRace("player")
local faction = (race == "TAUREN" or race == "ORC" or race == "TROLL" or race == "SCOURGE") and FACTION_HORDE or FACTION_ALLIANCE

Thanks for the tips. I haven't quite managed to get things working, but... I'll keep you posted. :)

It looks like I managed to get this to work. So thanks for all the help. :)

I was suprised though that:

local faction = (UnitRace("player") == "TAUREN" or race == "ORC" or race == "TROLL" or race == "SCOURGE") and FACTION_HORDE or FACTION_ALLIANCE

Doesn't seem to work. Must be my being new to LUA, is can anyone willing to explain to me why it doesnt'work?

The first return value is the localized name, the second the uppercase english name. That's why ckknight did:
