From 2019fa14fe25d17f8cac6ab5908927c9ba8a7ce1 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 406bc611c1..58fe5a8c4d 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -320,4 +320,10 @@ public class PaperWorldConfig { log("Treasure Maps will return already discovered locations"); } } + + 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 92e450f668..14fbea5460 100644 --- a/src/main/java/net/minecraft/server/Entity.java +++ b/src/main/java/net/minecraft/server/Entity.java @@ -184,6 +184,7 @@ public abstract class Entity implements INamableTileEntity, ICommandListener, Ke 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 567112ffc7..177051699f 100644 --- a/src/main/java/net/minecraft/server/EntityLiving.java +++ b/src/main/java/net/minecraft/server/EntityLiving.java @@ -2553,8 +2553,11 @@ 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.D(entity); } -- 2.21.0
