From dc179d975ef48acea548ee3a424345f87051255f 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/server/Entity.java b/src/main/java/net/minecraft/server/Entity.java index 3a248dbe37..d81ae00fb4 100644 --- a/src/main/java/net/minecraft/server/Entity.java +++ b/src/main/java/net/minecraft/server/Entity.java @@ -2610,6 +2610,11 @@ public abstract class Entity implements INamableTileEntity, ICommandListener, Ke if (blockposition == null) { // CraftBukkit if (dimensionmanager1.getType() == DimensionManager.THE_END && dimensionmanager == DimensionManager.OVERWORLD) { // CraftBukkit + // Paper start - Ensure spawn chunk is always loaded before calculating Y coordinate + if (!worldserver1.isLoaded(worldserver1.getSpawn())) { + worldserver1.getChunkAtWorldCoords(worldserver1.getSpawn()); + } + // Paper end // CraftBukkit start EntityPortalEvent event = CraftEventFactory.callEntityPortalEvent(this, worldserver1, worldserver1.getHighestBlockYAt(HeightMap.Type.MOTION_BLOCKING_NO_LEAVES, worldserver1.getSpawn()), 0); if (event == null) { -- 2.25.1
