From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Wed, 27 Apr 2016 22:09:52 -0400 Subject: [PATCH] Optimize Hoppers * Removes unnecessary extra calls to .update() that are very expensive * Lots of itemstack cloning removed. Only clone if the item is actually moved * Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items. However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on. * Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory * Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration * Don't check for Entities with Inventories if the block above us is also occluding (not just Inventoried) * Remove Streams from Item Suck In and restore restore 1.12 AABB checks which is simpler and no voxel allocations (was doing TWO Item Suck ins) diff --git a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java index edda2121f8c1046478beaa77030ebb36d403b334..7fbd501d70dccf869a4454e2789a5d68f2e15754 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -585,4 +585,13 @@ public class PaperWorldConfig { private void entitiesTargetWithFollowRange() { entitiesTargetWithFollowRange = getBoolean("entities-target-with-follow-range", entitiesTargetWithFollowRange); } + + public boolean cooldownHopperWhenFull = true; + public boolean disableHopperMoveEvents = false; + private void hopperOptimizations() { + cooldownHopperWhenFull = getBoolean("hopper.cooldown-when-full", cooldownHopperWhenFull); + log("Cooldown Hoppers when Full: " + (cooldownHopperWhenFull ?
