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/net/minecraft/server/MinecraftServer.java b/src/main/java/net/minecraft/server/MinecraftServer.java index 846dc9b607f40f1af3b4b7c7bbfe3c0803c0ad39..085943e5948c334792be1ad95e7ba4aa88ffe927 100644 --- a/src/main/java/net/minecraft/server/MinecraftServer.java +++ b/src/main/java/net/minecraft/server/MinecraftServer.java @@ -1407,6 +1407,7 @@ 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 537ce62ba966cc5765b9e7e48e1ba043fa1a6df9..ad42b1f9dae76a507a6eca51d096b7774905f623 100644 --- a/src/main/java/net/minecraft/world/level/Level.java +++ b/src/main/java/net/minecraft/world/level/Level.java @@ -168,6 +168,7 @@ 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;
