From a748467688abd31e2a1fee9f5f2e5339ff99c5b2 Mon Sep 17 00:00:00 2001 From: Aikar Date: Sun, 3 Feb 2013 05:10:21 -0500 Subject: [PATCH] Entity Activation Range This feature gives 3 new configurable ranges that if an entity of the matching type is outside of this radius of any player, will tick at 5% of its normal rate. This will drastically cut down on tick timings for entities that are not in range of a user to actually be "used". This change can have dramatic impact on gameplay if configured too low. Balance according to your servers desired gameplay. diff --git a/src/main/java/net/minecraft/server/Entity.java b/src/main/java/net/minecraft/server/Entity.java index 0c1350e..4d573e6 100644 --- a/src/main/java/net/minecraft/server/Entity.java +++ b/src/main/java/net/minecraft/server/Entity.java @@ -88,7 +88,7 @@ public abstract class Entity { public int ticksLived;
