From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jake Potrebic Date: Sun, 11 Dec 2022 23:47:22 -0800 Subject: [PATCH] Fix inconsistencies in dispense events regarding stack size The javadocs for BlockDispenseEvent suggest the ItemStack is a single item which is being dispensed. Before this fix, sometimes it was the whole stack before a single item had been taken. This fixes that so the stack size is always 1. diff --git a/src/main/java/net/minecraft/core/dispenser/BoatDispenseItemBehavior.java b/src/main/java/net/minecraft/core/dispenser/BoatDispenseItemBehavior.java index dff30954e4c588ee4cc79d3f6dab6fb456934d65..ddb264443f2e38b6348226016f9139727c588898 100644 --- a/src/main/java/net/minecraft/core/dispenser/BoatDispenseItemBehavior.java +++ b/src/main/java/net/minecraft/core/dispenser/BoatDispenseItemBehavior.java @@ -49,7 +49,7 @@ public class BoatDispenseItemBehavior extends DefaultDispenseItemBehavior { } // CraftBukkit start - ItemStack itemstack1 = stack.split(1);
