From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: CullanP Date: Thu, 3 Mar 2016 02:13:38 -0600 Subject: [PATCH] Avoid hopper searches if there are no items Hoppers searching for items and minecarts is the most expensive part of hopper ticking. We keep track of the number of minecarts and items in a chunk. If there are no items in the chunk, we skip searching for items. If there are no minecarts in the chunk, we skip searching for them. Usually hoppers aren't near items, so we can skip most item searches. And since minecart hoppers are used _very_ rarely near we can avoid alot of searching there. Combined, this adds up a lot. diff --git a/src/main/java/net/minecraft/world/level/Level.java b/src/main/java/net/minecraft/world/level/Level.java index b56fe14e7b7de95876ba2b1d084856d6935e591c..c4e679eca56ca756d2d7a9d2ffa2a56e5ab3f721 100644 --- a/src/main/java/net/minecraft/world/level/Level.java +++ b/src/main/java/net/minecraft/world/level/Level.java @@ -990,7 +990,7 @@ public abstract class Level implements LevelAccessor, AutoCloseable { } } - }); + }, predicate == net.minecraft.world.entity.EntitySelector.CONTAINER_ENTITY_SELECTOR); // Paper return list; } diff --git a/src/main/java/net/minecraft/world/level/entity/EntitySection.java b/src/main/java/net/minecraft/world/level/entity/EntitySection.java index 524f3c42964eb83c9109bcc548a1075f1e295411..e9aee7d11798c3bd990466f101e9e342686de11c 100644 --- a/src/main/java/net/minecraft/world/level/entity/EntitySection.java +++ b/src/main/java/net/minecraft/world/level/entity/EntitySection.java @@ -13,6 +13,10 @@ public class EntitySection { private static final Logger LOGGER = LogUtils.getLogger(); private final ClassInstanceMultiMap storage; private Visibility chunkStatus; + // Paper start - track number of items and minecarts + public int itemCount; + public int inventoryEntityCount; + // Paper end public EntitySection(Class entityClass, Visibility status) { this.chunkStatus = status; @@ -20,10 +24,24 @@ public class EntitySection { } public void add(T entity) { + // Paper start + if (entity instanceof net.minecraft.world.entity.item.ItemEntity) { + this.itemCount++; + } else if (entity instanceof net.minecraft.world.Container) { + this.inventoryEntityCount++; + } + // Paper end this.storage.add(entity); } public boolean remove(T entity) { + // Paper start + if (entity instanceof net.minecraft.world.entity.item.ItemEntity) { + this.itemCount--; + } else if (entity instanceof net.minecraft.world.Container) { + this.inventoryEntityCount--; + } + // Paper end return this.storage.remove(entity); } diff --git a/src/main/java/net/minecraft/world/level/entity/EntitySectionStorage.java b/src/main/java/net/minecraft/world/level/entity/EntitySectionStorage.java index 4c1e7c219e1ca153be4423347bd239ebaec4a31d..f54ca6383298848b2ee7108c41fcea593f924881 100644 --- a/src/main/java/net/minecraft/world/level/entity/EntitySectionStorage.java +++ b/src/main/java/net/minecraft/world/level/entity/EntitySectionStorage.java @@ -112,13 +112,20 @@ public class EntitySectionStorage { } public void getEntities(AABB box, Consumer action) { + // Paper start + this.getEntities(box, action, false); + } + public void getEntities(AABB box, Consumer action, boolean isContainerSearch) { + // Paper end this.forEachAccessibleNonEmptySection(box, (section) -> { + if (isContainerSearch && section.inventoryEntityCount <= 0) return; // Paper section.getEntities(box, action); }); } public void getEntities(EntityTypeTest filter, AABB box, Consumer action) { this.forEachAccessibleNonEmptySection(box, (section) -> { + if (filter.getBaseClass() == net.minecraft.world.entity.item.ItemEntity.class && section.itemCount <= 0) return; // Paper section.getEntities(filter, box, action); }); } diff --git a/src/main/java/net/minecraft/world/level/entity/LevelEntityGetter.java b/src/main/java/net/minecraft/world/level/entity/LevelEntityGetter.java index 9723a0ad61548c8c6c4c5ef20a150d5b17d80afd..da1ad0b2679e392ed81b50c15f012c63cb5c939e 100644 --- a/src/main/java/net/minecraft/world/level/entity/LevelEntityGetter.java +++ b/src/main/java/net/minecraft/world/level/entity/LevelEntityGetter.java @@ -17,6 +17,7 @@ public interface LevelEntityGetter { void get(EntityTypeTest filter, Consumer action); void get(AABB box, Consumer action); + void get(AABB box, Consumer action, boolean isContainerSearch); // Paper void get(EntityTypeTest filter, AABB box, Consumer action); } diff --git a/src/main/java/net/minecraft/world/level/entity/LevelEntityGetterAdapter.java b/src/main/java/net/minecraft/world/level/entity/LevelEntityGetterAdapter.java index d5129c12c79eb6fe6b7e5f8eed4d24226423f5fd..3b13f6ea36a3bfecabe09221eb5c48dddab119db 100644 --- a/src/main/java/net/minecraft/world/level/entity/LevelEntityGetterAdapter.java +++ b/src/main/java/net/minecraft/world/level/entity/LevelEntityGetterAdapter.java @@ -38,7 +38,13 @@ public class LevelEntityGetterAdapter implements LevelEn @Override public void get(AABB box, Consumer action) { - this.sectionStorage.getEntities(box, action); + // Paper start + this.get(box, action, false); + } + @Override + public void get(AABB box, Consumer action, boolean isContainerSearch) { + this.sectionStorage.getEntities(box, action, isContainerSearch); + // Paper end } @Override
