From 4c0a4516fb82d1b4436faa124c595d28c46d3f02 Mon Sep 17 00:00:00 2001 From: Techcable Date: Sat, 18 Jun 2016 01:01:37 -0500 Subject: [PATCH] Make entities look for hoppers Every tick hoppers try and find an block-inventory to extract from. If no tile entity is above the hopper (which there often isn't) it will do a bounding box search for minecart chests and minecart hoppers. If it can't find an inventory, it will then look for a dropped item, which is another bounding box search. This patch eliminates that expensive check by having dropped items and minecart hoppers/chests look for hoppers instead. Hoppers are tile entities meaning you can do a simple tile entity lookup to find the nearest hopper in range. Pushing out of hoppers causes a bouding box lookup, which this patch replaces with a tile entity lookup. This patch may causes a decrease in the performance of dropped items, which is why it can be disabled in the configuration. diff --git a/src/main/java/com/destroystokyo/paper/HopperPusher.java b/src/main/java/com/destroystokyo/paper/HopperPusher.java new file mode 100644 index 0000000..5ff43e2 --- /dev/null +++ b/src/main/java/com/destroystokyo/paper/HopperPusher.java @@ -0,0 +1,59 @@ +package com.destroystokyo.paper;
