From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Byteflux Date: Wed, 2 Mar 2016 11:59:48 -0600 Subject: [PATCH] Optimize explosions The process of determining an entity's exposure from explosions can be expensive when there are hundreds or more entities in range. This patch adds a per-tick cache that is used for storing and retrieving an entity's exposure during an explosion. diff --git a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java index bc35bdd9cbd544ae2ab27ad042d7d1b3166db9a6..2b0a75dc2e292e655ca3300f64bc1211b3adeceb 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -201,4 +201,10 @@ public class PaperWorldConfig { disableEndCredits = getBoolean("game-mechanics.disable-end-credits", false); log("End credits disabled: " + disableEndCredits); } + + public boolean optimizeExplosions; + private void optimizeExplosions() { + optimizeExplosions = getBoolean("optimize-explosions", false); + log("Optimize explosions: " + optimizeExplosions); + } } diff --git a/src/main/java/net/minecraft/server/MinecraftServer.java b/src/main/java/net/minecraft/server/MinecraftServer.java index 18f03367174651b93682d5e5f4350d8c7e6e3b98..ac88d79685c5f988d02122bce38d5af41fe11445 100644 --- a/src/main/java/net/minecraft/server/MinecraftServer.java +++ b/src/main/java/net/minecraft/server/MinecraftServer.java @@ -1439,6 +1439,7 @@ public abstract class MinecraftServer extends ReentrantBlockableEventLoop>> 32)); + temp = Double.doubleToLongBits(posY); + result = 31 * result + (int) (temp ^ (temp >>> 32)); + temp = Double.doubleToLongBits(posZ); + result = 31 * result + (int) (temp ^ (temp >>> 32)); + temp = Double.doubleToLongBits(minX); + result = 31 * result + (int) (temp ^ (temp >>> 32)); + temp = Double.doubleToLongBits(minY); + result = 31 * result + (int) (temp ^ (temp >>> 32)); + temp = Double.doubleToLongBits(minZ); + result = 31 * result + (int) (temp ^ (temp >>> 32)); + temp = Double.doubleToLongBits(maxX); + result = 31 * result + (int) (temp ^ (temp >>> 32)); + temp = Double.doubleToLongBits(maxY); + result = 31 * result + (int) (temp ^ (temp >>> 32)); + temp = Double.doubleToLongBits(maxZ); + result = 31 * result + (int) (temp ^ (temp >>> 32)); + return result; + } + } + // Paper end } diff --git a/src/main/java/net/minecraft/world/level/Level.java b/src/main/java/net/minecraft/world/level/Level.java index 8653fa072825c024e0fb620bdada4adc936b0490..7309226b6ee96db7330d712c41157bfde0d03d37 100644 --- a/src/main/java/net/minecraft/world/level/Level.java +++ b/src/main/java/net/minecraft/world/level/Level.java @@ -151,6 +151,7 @@ public abstract class Level implements LevelAccessor, AutoCloseable { private org.spigotmc.TickLimiter entityLimiter; private org.spigotmc.TickLimiter tileLimiter; private int tileTickPosition; + public final Map explosionDensityCache = new HashMap<>(); // Paper - Optimize explosions public CraftWorld getWorld() { return this.world;
