From fc58b79f9d2af4b4302702788ecf20bf61258e24 Mon Sep 17 00:00:00 2001 From: Aikar Date: Thu, 3 Nov 2016 20:28:12 -0400 Subject: [PATCH] Don't load Chunks from Hoppers and other things Hoppers call this to I guess "get the primary side" of a double sided chest. If the double sided chest crosses chunk lines, it causes the chunk to load. This will end up causing sync chunk loads, which will unload with Chunk GC, only to be reloaded again the next tick. This of course is undesirable, so just return the loaded side as "primary" and treat it as a single chest if the other sides are unloaded diff --git a/src/main/java/net/minecraft/server/BlockChest.java b/src/main/java/net/minecraft/server/BlockChest.java index 9c4d1c9..dd1c1a3 100644 --- a/src/main/java/net/minecraft/server/BlockChest.java +++ b/src/main/java/net/minecraft/server/BlockChest.java @@ -339,7 +339,13 @@ public class BlockChest extends BlockTileEntity { while (iterator.hasNext()) { EnumDirection enumdirection = (EnumDirection) iterator.next(); BlockPosition blockposition1 = blockposition.shift(enumdirection); - Block block = world.getType(blockposition1).getBlock(); + // Paper start - don't load chunks if the other side of the chest is in unloaded chunk + final IBlockData type = world.getTypeIfLoaded(blockposition1); // Paper + if (type == null) { + continue; + } + Block block = type.getBlock(); + // Paper end if (block == this) { if (this.e(world, blockposition1)) { -- 2.9.3
