From fa363af6a7a85bf4630df7d709e16e0d5c757ee5 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 5c50c62e5..e49eb0caf 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -360,4 +360,10 @@ 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 e1944774c..b613d3d15 100644 --- a/src/main/java/net/minecraft/server/Entity.java +++ b/src/main/java/net/minecraft/server/Entity.java @@ -182,6 +182,7 @@ 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 f2e38b9f3..b7923a1a5 100644 --- a/src/main/java/net/minecraft/server/EntityLiving.java +++ b/src/main/java/net/minecraft/server/EntityLiving.java @@ -2354,8 +2354,11 @@ 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); } -- 2.20.1
