From 905de1056b56b89387ff40bdfa7ff1fb970f5979 Mon Sep 17 00:00:00 2001 From: Aikar Date: Mon, 30 Apr 2018 17:15:26 -0400 Subject: [PATCH] Block Enderpearl Travel Exploit Players are able to use alt accounts and enderpearls to travel long distances utilizing the pearls in unloaded chunks and loading the chunk later when convenient. This disables that by not saving the thrower when the chunk is unloaded. This is mainly useful for survival servers that do not allow freeform teleporting. diff --git a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java index 99d681ef1..03a9a96fc 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -513,4 +513,10 @@ public class PaperWorldConfig { allowPermaChunkLoaders = getBoolean("game-mechanics.allow-permanent-chunk-loaders", allowPermaChunkLoaders); log("Allow Perma Chunk Loaders: " + (allowPermaChunkLoaders ?
