I was making a Minecraft mini game, so I was going to use a resource pack to rename the items, (such as Sphax PureBDcraft does), but when it was edited, some items I renamed such as Redstone appeared as:
'Redstoneitem.snowball.name=Snowball'
I renamed Redstone to '+800', so it was in the game named:
'+800item.snowball.name=Snowball'
Glowstone did the same, and also with Golden Apples.
But all the other renamed items appeared as how they were meant to be.
(Diamonds = +2,000, Nether Stars = +1,250, etc.)
I have the Language file used in the attachments.
(If there's a better place to post this, please tell me)
