Subject: [PATCH] Handle Item Meta Inconsistencies
|
|
|
|
First, Enchantment order would blow away seeing 2 items as the same,
|
|
however the Client forces enchantment list in a certain order, as well
|
|
as does the /enchant command. Anvils can insert it into forced order,
|
|
causing 2 same items to be considered different.
|
|
|
|
This change makes unhandled NBT Tags and Enchantments use a sorted tree map,
|
|
so they will always be in a consistent order.
|
|
|
|
Additionally, the old enchantment API was never updated when ItemMeta
|
|
was added, resulting in 2 different ways to modify an items enchantments.
|
|
|
|
For consistency, the old API methods now forward to use the
|
|
ItemMeta API equivalents, and should deprecate the old API's.
