From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Bjarne Koll Date: Tue, 10 Jan 2023 21:06:42 +0100 Subject: [PATCH] Correctly shrink items during EntityResurrectEvent The EntityResurrectEvent logic is supposed to locate a totem of undying in any of the interaction slots of the player inventory and then, if the called EntityResurrectEvent is not cancelled, shrink that item by 1, usually reducing it to zero. For this, the logic iterates over the items in the interaction slots and breaks out the loop if a totem of undying was found. However, even if no totem of undying was found, the iteration item stack variable remains as a refernce to the last interaction slot probed. Plugins uncancelling a EntityResurrectEvent, which is published pre-cancelled to listeners if no totem of undying could be found, would hence cause the server logic to shrink completely unrelated items found in, at the writing of this patch, the players off hand slot. This patch corrects this behaviour by only shrinking the item if a totem of undying was found and the event was called uncancelled. diff --git a/src/main/java/net/minecraft/world/entity/LivingEntity.java b/src/main/java/net/minecraft/world/entity/LivingEntity.java index 205c7bdc03c86229a100bd535db16b502d99ba24..f6f2f62cf9a4c7876c251766ad7c32f6f046eb2e 100644 --- a/src/main/java/net/minecraft/world/entity/LivingEntity.java +++ b/src/main/java/net/minecraft/world/entity/LivingEntity.java @@ -1644,7 +1644,7 @@ public abstract class LivingEntity extends Entity implements Attackable { this.level().getCraftServer().getPluginManager().callEvent(event); if (!event.isCancelled()) { - if (!itemstack1.isEmpty()) { + if (!itemstack1.isEmpty() && itemstack != null) { // Paper - only reduce item if actual totem was found itemstack1.shrink(1); } if (itemstack != null && this instanceof ServerPlayer) {
