How to detect if the client is WotLK?

[Duugu]

See topic. Any idea?

[Mikord]

There are several ways you can do it.

One of the easiest is to check the TOC version via GetBuildInfo.

http://www.wowwiki.com/API_GetBuildInfo

local tocVersion = select(4, GetBuildInfo())
if tocVersion >= 30000 then
 -- It's WotLK....
end

This will do the job. Thanks a lot Mikord.

I toss this in any addon that needs to do different things in wrath than live, then just test against the global...

if IS_WRATH_BUILD == nil then IS_WRATH_BUILD = (select(4, GetBuildInfo()) >= 30000) end

some just do

local WotLK = not not ToggleAchievementFrame

[Tekkub]

GetBuildInfo is much cleaner, what if they remove that toggle function and use something else? I saw them add a togglepanel function of some sort recently, they might decide they should use that.

They have added a function for this specifically:

GetAccountExpansionLevel()

1 = Classic Wow
2 = The Burning Crusade
3 = Wrath of the Lich King

It'll return the value based on the level of expansions the user has.

[Tekkub]

What about users that have the new client, but have not purchased the expansion? It's possible for the user to have 2.4.3, but not BC.

[Fritos]

Oh I know, was giving another alternative if they are just looking to see if a specific expansion is installed.

I currently use the same code as GetBuildInfo() in my mod, was just snooping through the Interface Kit files and saw this.

Thanks again for all the replies. There are much more way than expected.

Although it doesn't really matter right now (it's all about the different UIDropDown parameters and the UnitAura function) I'll use the patch level (GetBuildInfo). Seems to be most future-proof.
