[SOLVED] [1.7.10] Quick Questions

Greetings!

some quick questions, regarding efficiency.

1) I try to get a list of all the items. Is this an efficient way?

GameData.getItemRegistry().getKeys()

2) for each String s in that set, I do [1] to get an Item Object. To get the display name (not the unlocalised name, I want the name it shows the user, is it necessary to make a new ItemStack with that item, and do [2] or can it be retrieved from the item directly? I couldn't find anything in the Item class.

[1]

GameData.getItemRegistry().getObject(s)

[2]

stack.getDisplayName()

That's all for now. I might edit this post and bump this thread if I have more relatively easy problems.

Thanks in advance,

Pancake.

EDIT: about (2) ... I just remembered Items can have metadata, and one metadata of an item can have a different name than another metadata. I'll just make the list of items based on the output of all the recipes. Thanks anyways... for reading and silently judging me.
