From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: AJMFactsheets Date: Wed, 22 Jan 2020 19:52:28 -0600 Subject: [PATCH] Fix items vanishing through end portal If the Paper configuration option "keep-spawn-loaded" is set to false, items entering the overworld from the end will spawn at Y = 0. This is due to logic in the getHighestBlockYAt method in World.java only searching the heightmap if the chunk is loaded. Quickly loading the exact world spawn chunk before searching the heightmap resolves the issue without having to load all spawn chunks. diff --git a/src/main/java/net/minecraft/world/entity/Entity.java b/src/main/java/net/minecraft/world/entity/Entity.java index 257be4dd3f38c089dd970b9ac6f292b4f010a01c..98db75a013905ddd38ffd26d615ad8d02d8ddd22 100644 --- a/src/main/java/net/minecraft/world/entity/Entity.java +++ b/src/main/java/net/minecraft/world/entity/Entity.java @@ -3363,6 +3363,7 @@ public abstract class Entity implements Nameable, EntityAccess, CommandSource, S if (flag1) { blockposition1 = ServerLevel.END_SPAWN_POINT; } else { + destination.getChunkAt(destination.getSharedSpawnPos()); // Paper - Ensure spawn chunk is always loaded before calculating Y coordinate blockposition1 = destination.getHeightmapPos(Heightmap.Types.MOTION_BLOCKING_NO_LEAVES, destination.getSharedSpawnPos()); } // CraftBukkit start
