Am I using the method correctly? It doesn't seem to be working.

 

Code:

LanguageRegistry.instance().injectLanguage("en_US", langMap);

 

Here's what the hash map looks like:

Just use assets

Why don't you just make a language file? It's very simple, just make a en_US.lang file in 'assets/{modid}/lang' and just put it in like this:

tile.hellStoneOre.name=Hell Stone Ore[/code]

That's how simple it is!
