From d059aee7f3cf690c8173570c63b736fdf971921f 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 3ca579e38..1c1f39524 100644 --- a/src/main/java/net/minecraft/server/Chunk.java +++ b/src/main/java/net/minecraft/server/Chunk.java @@ -723,6 +723,7 @@ 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.chunkY); } diff --git a/src/main/java/net/minecraft/server/World.java b/src/main/java/net/minecraft/server/World.java index 08ad88c14..9befa890b 100644 --- a/src/main/java/net/minecraft/server/World.java +++ b/src/main/java/net/minecraft/server/World.java @@ -1192,12 +1192,15 @@ public abstract class World implements IEntityAccess, GeneratorAccess, IIBlockAc 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) { @@ -1258,12 +1261,17 @@ public abstract class World implements IEntityAccess, GeneratorAccess, IIBlockAc this.methodProfiler.exit(); this.methodProfiler.enter("remove"); if (entity.dead) { + // Paper start + /* j = entity.chunkX; int l = entity.chunkZ; 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 @@ -1308,7 +1316,7 @@ public abstract class World implements IEntityAccess, GeneratorAccess, IIBlockAc 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.scheduledForUnload == null; @@ -1344,8 +1352,11 @@ public abstract class World implements IEntityAccess, GeneratorAccess, IIBlockAc 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 } } } -- 2.21.0
