From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Sun, 22 Jan 2017 18:07:56 -0500 Subject: [PATCH] Cap Entity Collisions Limit a single entity to colliding a max of configurable times per tick. This will alleviate issues where living entities are hoarded in 1x1 pens This is not tied to the maxEntityCramming rule. Cramming will still apply just as it does in Vanilla, but entity pushing logic will be capped. You can set this to 0 to disable collisions. diff --git a/src/main/java/net/minecraft/world/entity/Entity.java b/src/main/java/net/minecraft/world/entity/Entity.java index ea25e9ab6c1d54e834a05951d2369d6e2e3a3fb3..78cb145f72efaaf535b6f933b3ca990a3f909608 100644 --- a/src/main/java/net/minecraft/world/entity/Entity.java +++ b/src/main/java/net/minecraft/world/entity/Entity.java @@ -401,6 +401,7 @@ public abstract class Entity implements SyncedDataHolder, Nameable, EntityAccess public long activatedTick = Integer.MIN_VALUE; public void inactiveTick() { } // Spigot end + protected int numCollisions = 0; // Paper - Cap entity collisions // Paper start - Entity origin API @javax.annotation.Nullable private org.bukkit.util.Vector origin; diff --git a/src/main/java/net/minecraft/world/entity/LivingEntity.java b/src/main/java/net/minecraft/world/entity/LivingEntity.java index 65f75b10460563c1305d97fa5337f035ba915e4b..57ba53cf9f84b21185bbaefd482f9d6dea2cb772 100644 --- a/src/main/java/net/minecraft/world/entity/LivingEntity.java +++ b/src/main/java/net/minecraft/world/entity/LivingEntity.java @@ -3474,10 +3474,12 @@ public abstract class LivingEntity extends Entity implements Attackable { } Iterator iterator1 = list.iterator(); + this.numCollisions = Math.max(0, this.numCollisions - this.level().paperConfig().collisions.maxEntityCollisions); // Paper - Cap entity collisions - while (iterator1.hasNext()) { + while (iterator1.hasNext() && this.numCollisions < this.level().paperConfig().collisions.maxEntityCollisions) { // Paper - Cap entity collisions Entity entity1 = (Entity) iterator1.next(); - + entity1.numCollisions++; // Paper - Cap entity collisions + this.numCollisions++; // Paper - Cap entity collisions this.doPush(entity1); } }
