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 by tracking changes to the event via an internal event implementation. * 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/io/papermc/paper/event/inventory/PaperInventoryMoveItemEvent.java b/src/main/java/io/papermc/paper/event/inventory/PaperInventoryMoveItemEvent.java new file mode 100644 index 0000000000000000000000000000000000000000..0000000000000000000000000000000000000000 --- /dev/null +++ b/src/main/java/io/papermc/paper/event/inventory/PaperInventoryMoveItemEvent.java @@ -0,0 +0,0 @@ +package io.papermc.paper.event.inventory; + +import org.bukkit.event.inventory.InventoryMoveItemEvent; +import org.bukkit.inventory.Inventory; +import org.bukkit.inventory.ItemStack; +import org.checkerframework.checker.nullness.qual.NonNull; +import org.checkerframework.framework.qual.DefaultQualifier; +import org.jetbrains.annotations.NotNull; + +@DefaultQualifier(NonNull.class) +public class PaperInventoryMoveItemEvent extends InventoryMoveItemEvent { + + public boolean calledSetItem; + public boolean calledGetItem; + + public PaperInventoryMoveItemEvent(final @NotNull Inventory sourceInventory, final @NotNull ItemStack itemStack, final @NotNull Inventory destinationInventory, final boolean didSourceInitiate) { + super(sourceInventory, itemStack, destinationInventory, didSourceInitiate); + } + + @Override + public ItemStack getItem() { + this.calledGetItem = true; + return super.getItem(); + } + + @Override + public void setItem(final ItemStack itemStack) { + super.setItem(itemStack); + this.calledSetItem = true; + } +} diff --git a/src/main/java/net/minecraft/server/MinecraftServer.java b/src/main/java/net/minecraft/server/MinecraftServer.java index 0000000000000000000000000000000000000000..0000000000000000000000000000000000000000 100644 --- a/src/main/java/net/minecraft/server/MinecraftServer.java +++ b/src/main/java/net/minecraft/server/MinecraftServer.java @@ -0,0 +0,0 @@ public abstract class MinecraftServer extends ReentrantBlockableEventLoop 0; // Paper - BlockPhysicsEvent worldserver.hasEntityMoveEvent = io.papermc.paper.event.entity.EntityMoveEvent.getHandlerList().getRegisteredListeners().length > 0; // Paper - Add EntityMoveEvent + net.minecraft.world.level.block.entity.HopperBlockEntity.skipHopperEvents = worldserver.paperConfig().hopper.disableMoveEvent || org.bukkit.event.inventory.InventoryMoveItemEvent.getHandlerList().getRegisteredListeners().length == 0; // Paper - Perf: Optimize Hoppers this.profiler.push(() -> { String s = String.valueOf(worldserver); diff --git a/src/main/java/net/minecraft/world/item/ItemStack.java b/src/main/java/net/minecraft/world/item/ItemStack.java index 0000000000000000000000000000000000000000..0000000000000000000000000000000000000000 100644 --- a/src/main/java/net/minecraft/world/item/ItemStack.java +++ b/src/main/java/net/minecraft/world/item/ItemStack.java @@ -0,0 +0,0 @@ public final class ItemStack implements DataComponentHolder { } public ItemStack copy() { - if (this.isEmpty()) { + // Paper start - Perf: Optimize Hoppers + return this.copy(false); + } + + public ItemStack copy(boolean originalItem) { + if (!originalItem && this.isEmpty()) { + // Paper end - Perf: Optimize Hoppers return ItemStack.EMPTY; } else { - ItemStack itemstack = new ItemStack(this.getItem(), this.count, this.components.copy()); + ItemStack itemstack = new ItemStack(originalItem ?
