Not every item in Minecraft is "special". Some items are plain old regular items. And please stop spamming random threads. And PS: apples give you health, and feathers are used to craft arrows.
Lots of items are needed to craft something but they are not in "item" folder —,— . But almost all items there have some special feature (tools, Cake, cauldron, flint and steel) PS: steak gives you health too
Because it's pointless! And it doesn't belong in Plugin Development! Don't make me report you for spamming.
It is pointless because you don't understand the question. Now, stop spamming yourself. Because of item name. It seems that it is the only way to give items names.
