getting player class(Warlock hunter etc)

[akgis]

How can I get the class that its currently played to do something like

If class="warlock" then
...
end

[Phanx]

local className, englishClassName = UnitClass("player")
if englishClassName == "WARLOCK" then
    -- do something
end

For basic stuff like this, you can usually find the answer by using your browser's "find in page" feature on the list of global functions on Wowpedia.

[akgis]

ok thanks for that page.

Would that works on a Spanish client for example?

[semlar]

The first value is the localized name, the second is not localized so will always be "WARLOCK" regardless of the client's language.

To expand on what semlar said... For your if-then statement above:

If you only want your addon to work on the Spanish client, use the first return.

If you want your addon to work regardless of localization (on any client), use the second return.

Adding to that, you should use the first return when displaying a class's name as text on the screen, so it'll automatically be localized.
