Lng2 File usage
lng2 files or lang files are used for localization. Mostly found in Assets\tpp\pack\ui\lang\lang_default_data_<language>.fpk
Language codes - eng,fre,ger,ita,jpn,por,rus,spa
lng2 files be converted to and from editable xml files using LangTool
The converted lng2 xml localization string entries will look like:
<Entry Key="956942769" Value="Obtained Poster [%s] [GMP +%d]" />
<Entry Key="4191827342" Value="Soviet Soldier" />
The Key is a CityHash64WithSeeds of the lua key string, most commonly reffered to at langId in the lua scripts.
Provide it with a text file of strings (1 per line) and it will output same list with hashes appended.
In lua a string is hashed using the engine function Fox.StrCode32(string)
Supports 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 number, number as it's paramaters, other combinations lock the game up.
Evidence from other localization strings in lng2 files suggest other functions are less restricted.
In the above entries the langId/Keys resolve from:
announce_get_gravure and key_poster_3500
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 completley new .lng2 files.
