From a57ea7eda73f5bdf5359d585762275d4f7282b54 Mon Sep 17 00:00:00 2001 From: Aikar Date: Wed, 4 Jul 2018 03:39:51 -0400 Subject: [PATCH] Avoid Chunk Lookups for Entity/TileEntity Current Chunk In many places where we simply want the current chunk the entity is in, instead of doing a hashmap lookup for it, we now have access to the object directly on the Entity/TileEntity object we can directly grab. Use that local value instead to reduce lookups in many hot places. diff --git a/src/main/java/net/minecraft/server/Chunk.java b/src/main/java/net/minecraft/server/Chunk.java index 7a7d656926..b37fa3829b 100644 --- a/src/main/java/net/minecraft/server/Chunk.java +++ b/src/main/java/net/minecraft/server/Chunk.java @@ -721,6 +721,7 @@ public class Chunk implements IChunkAccess { ((HeightMap) this.heightMap.get(heightmap_type)).a(along); } + public void removeEntity(Entity entity) { b(entity); } // Paper - OBFHELPER public void b(Entity entity) { this.a(entity, entity.af); } diff --git a/src/main/java/net/minecraft/server/World.java b/src/main/java/net/minecraft/server/World.java index 00eb342f8c..127dcedc97 100644 --- a/src/main/java/net/minecraft/server/World.java +++ b/src/main/java/net/minecraft/server/World.java @@ -1208,12 +1208,15 @@ public abstract class World implements GeneratorAccess, IIBlockAccess, AutoClose int j; // Paper start - Set based removal lists for (Entity e : this.g) { + /* j = e.getChunkZ(); int k = e.getChunkX(); if (e.inChunk && this.isChunkLoaded(k, j, true)) { this.getChunkAt(k, j).b(e); - } + }*/ + Chunk chunk = e.inChunk ? e.getCurrentChunk() : null; + if (chunk != null) chunk.removeEntity(e); } for (Entity e : this.g) { @@ -1274,12 +1277,17 @@ public abstract class World implements GeneratorAccess, IIBlockAccess, AutoClose this.methodProfiler.e(); this.methodProfiler.a("remove"); if (entity.dead) { + // Paper start + /* j = entity.ae; int l = entity.ag; if (entity.inChunk && this.isChunkLoaded(j, l, true)) { this.getChunkAt(j, l).b(entity); - } + }*/ + Chunk chunk = entity.inChunk ? entity.getCurrentChunk() : null; + if (chunk != null) chunk.removeEntity(entity); + // Paper end guardEntityList = false; // Spigot this.entityList.remove(this.tickPosition--); // CraftBukkit - Use field for loop variable @@ -1324,7 +1332,7 @@ public abstract class World implements GeneratorAccess, IIBlockAccess, AutoClose BlockPosition blockposition = tileentity.getPosition(); // Paper start - Skip ticking in chunks scheduled for unload - net.minecraft.server.Chunk chunk = this.getChunkIfLoaded(blockposition); + net.minecraft.server.Chunk chunk = tileentity.getCurrentChunk(); boolean shouldTick = chunk != null; if(this.paperConfig.skipEntityTickingInChunksScheduledForUnload) shouldTick = shouldTick && !chunk.isUnloading() && chunk.scheduledForUnload == null; @@ -1360,8 +1368,11 @@ public abstract class World implements GeneratorAccess, IIBlockAccess, AutoClose tilesThisCycle--; this.tileEntityListTick.remove(tileTickPosition--); //this.tileEntityList.remove(tileentity); // Paper - remove unused list - if (this.isLoaded(tileentity.getPosition())) { - this.getChunkAtWorldCoords(tileentity.getPosition()).d(tileentity.getPosition()); + // Paper start + net.minecraft.server.Chunk chunk = tileentity.getCurrentChunk(); + if (chunk != null) { + chunk.removeTileEntity(tileentity.getPosition()); + // Paper end } } } -- 2.18.0
