The Key is a StrCode32 of the lua key string, most commonly refereed to at langId in the lua scripts.

The second entry langId actually resolves from key_poster_3500, but was omitted from the dictionary for this example.

Localization strings support string formatting characters, in the above entries seen as %s for another langId, %d for a number.

What it will accept however seems dependent on the function. AnnounceLogViewLangId will only accept the string, number, or two numbers as it’s parameters, other combinations lock the game up.

Evidence from other localization strings in lng2 files suggest other functions are less restricted.

Lua usage:

TppUICommand.AnnounceLogViewLangId("announce_get_gravure","key_poster_3500",500)

If a langId is called without a matching entry in the particular language lang file it will return empty.

Fox engine will load all lng2 files from a pack enabling addition of completely new .lng2 files.

The following is a partial list of lng2 files and an explanation of what they are:
