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 6ce232c623d86af20b74d7ee1e7b258cd7342d24..c11b4ff3907a0041db35a1dd7940a42755db3f0d 100644 --- a/src/main/java/net/minecraft/world/entity/Entity.java +++ b/src/main/java/net/minecraft/world/entity/Entity.java @@ -3007,6 +3007,9 @@ public abstract class Entity implements Nameable, EntityAccess, CommandSource, n BlockPos blockposition1; if (flag1) { + // Paper start - Ensure spawn chunk is always loaded before calculating Y coordinate + this.level.getChunkAt(this.level.getSharedSpawnPos()); + // Paper end blockposition1 = ServerLevel.END_SPAWN_POINT; } else { blockposition1 = destination.getHeightmapPos(Heightmap.Types.MOTION_BLOCKING_NO_LEAVES, destination.getSharedSpawnPos());
