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 77e58257dc3fb517aeca8f8436a4279aa133b570..9842e4d39130f45481b643df38ee4b25076c5c08 100644 --- a/src/main/java/net/minecraft/world/level/Level.java +++ b/src/main/java/net/minecraft/world/level/Level.java @@ -985,7 +985,7 @@ 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 e3027cae3674502bdc34fdbd7002980515ffc837..07691d38960add169d24bc830ac7b951bd5afaef 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 { protected static final Logger LOGGER = LogManager.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); } @@ -42,7 +60,7 @@ public class EntitySection { for(T entityAccess : collection) { U entityAccess2 = (U)((EntityAccess)type.tryCast(entityAccess)); if (entityAccess2 != null && entityAccess.getBoundingBox().intersects(box)) { - action.accept((T)entityAccess2); + action.accept(entityAccess2); // Paper - decompile fixes } } 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 13df7889b2b5249fb81c54fadf55315a4c515116..984e940a1d8060e5945a6efd10c9f81bed2bf057 100644 --- a/src/main/java/net/minecraft/world/level/entity/EntitySectionStorage.java +++ b/src/main/java/net/minecraft/world/level/entity/EntitySectionStorage.java @@ -111,13 +111,19 @@ public class EntitySectionStorage { } public void getEntities(AABB box, Consumer action) { + // Paper start + } + 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
