From a58395902b9acad1f9b28d849027857361b4fbf7 Mon Sep 17 00:00:00 2001 From: md_5 <md_5@live.com.au> Date: Sun, 17 Mar 2013 19:02:50 +1100 Subject: [PATCH] Faster UUID for entities It is overkill to create a new SecureRandom on each entity create and then use it to make a new Entity ID for every entity instance created. Instead we will just use a pseudo random UUID based off the random instance we already have. diff --git a/src/main/java/net/minecraft/server/Entity.java b/src/main/java/net/minecraft/server/Entity.java index e438df5..700e450 100644 --- a/src/main/java/net/minecraft/server/Entity.java +++ b/src/main/java/net/minecraft/server/Entity.java @@ -132,7 +132,7 @@ public abstract class Entity { this.maxFireTicks = 1; this.justCreated = true; this.datawatcher = new DataWatcher(); - this.uniqueID = UUID.randomUUID(); + this.uniqueID = new UUID(random.nextLong(), random.nextLong()); // Spigot this.at = EnumEntitySize.SIZE_2; this.world = world; this.setPosition(0.0D, 0.0D, 0.0D); -- 1.8.1.2
