From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Thu, 28 May 2015 23:00:19 -0400 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. diff --git a/src/main/java/net/minecraft/world/item/enchantment/ItemEnchantments.java b/src/main/java/net/minecraft/world/item/enchantment/ItemEnchantments.java index b49eb019cce58049c2b3a0e80e3d08998b16f7ea..af18de11dd55938b6091f5ab183bd3fe4e8df152 100644 --- a/src/main/java/net/minecraft/world/item/enchantment/ItemEnchantments.java +++ b/src/main/java/net/minecraft/world/item/enchantment/ItemEnchantments.java @@ -27,15 +27,27 @@ import net.minecraft.tags.TagKey;
