From d378a0ea944732d41e4d3095add7fc25171b2b6e 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/com/destroystokyo/paper/PaperWorldConfig.java b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java index 61efcc479..4898e8bce 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -408,4 +408,10 @@ public class PaperWorldConfig { private void armorStandEntityLookups() { armorStandEntityLookups = getBoolean("armor-stands-do-collision-entity-lookups", true); } + + public int maxCollisionsPerEntity; + private void maxEntityCollision() { + maxCollisionsPerEntity = getInt( "max-entity-collisions", this.spigotConfig.getInt("max-entity-collisions", 8) ); + log( "Max Entity Collisions: " + maxCollisionsPerEntity ); + } } diff --git a/src/main/java/net/minecraft/server/Entity.java b/src/main/java/net/minecraft/server/Entity.java index 6fcced926..cfeff7c48 100644 --- a/src/main/java/net/minecraft/server/Entity.java +++ b/src/main/java/net/minecraft/server/Entity.java @@ -168,6 +168,7 @@ public abstract class Entity implements ICommandListener { public final boolean defaultActivationState; public long activatedTick = Integer.MIN_VALUE; public boolean fromMobSpawner; + protected int numCollisions = 0; // Paper public void inactiveTick() { } // Spigot end diff --git a/src/main/java/net/minecraft/server/EntityLiving.java b/src/main/java/net/minecraft/server/EntityLiving.java index 7242da9cc..53486e205 100644 --- a/src/main/java/net/minecraft/server/EntityLiving.java +++ b/src/main/java/net/minecraft/server/EntityLiving.java @@ -2132,8 +2132,11 @@ public abstract class EntityLiving extends Entity { } } - for (j = 0; j < list.size(); ++j) { + numCollisions = Math.max(0, numCollisions - world.paperConfig.maxCollisionsPerEntity); // Paper + for (j = 0; j < list.size() && numCollisions < world.paperConfig.maxCollisionsPerEntity; ++j) { // Paper Entity entity = (Entity) list.get(j); + entity.numCollisions++; // Paper + numCollisions++; // Paper this.C(entity); } -- 2.12.2
