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/AbstractProjectileDispenseBehavior.java b/src/main/java/net/minecraft/core/dispenser/AbstractProjectileDispenseBehavior.java index e22d71c371952e91b838d10206d3dcdf9dc8716d..155bd3d6d9c7d3cac7fd04de8210301251d1e17a 100644 --- a/src/main/java/net/minecraft/core/dispenser/AbstractProjectileDispenseBehavior.java +++ b/src/main/java/net/minecraft/core/dispenser/AbstractProjectileDispenseBehavior.java @@ -27,7 +27,7 @@ public abstract class AbstractProjectileDispenseBehavior extends DefaultDispense // CraftBukkit start // iprojectile.shoot((double) enumdirection.getStepX(), (double) ((float) enumdirection.getStepY() + 0.1F), (double) enumdirection.getStepZ(), this.getPower(), this.getUncertainty());
