From 59453f66754cfe10b9f819a1d715a4e8d10ac208 Mon Sep 17 00:00:00 2001 From: Aikar Date: Sun, 12 Apr 2020 23:56:29 -0400 Subject: [PATCH] Fix incorrectly loading chunks on a cancelled interact event A players previous block break location is held onto permanently, and if an interact event is cancelled, the client sends a stop breaking block packet This then tries to update client about that old location. This old location might then be in a now unloaded chunk, and it caused it to load. We now also clear reference to it once abort destroy block is ran to stop trying to send updates about the old block anyways. --- ...t-allow-digging-into-unloaded-chunks.patch | 24 +++++++++- Spigot-Server-Patches/0385-Anti-Xray.patch | 44 +++++++++---------- 2 files changed, 44 insertions(+), 24 deletions(-) diff --git a/Spigot-Server-Patches/0327-Don-t-allow-digging-into-unloaded-chunks.patch b/Spigot-Server-Patches/0327-Don-t-allow-digging-into-unloaded-chunks.patch index c26a49cda..b315113aa 100644 --- a/Spigot-Server-Patches/0327-Don-t-allow-digging-into-unloaded-chunks.patch +++ b/Spigot-Server-Patches/0327-Don-t-allow-digging-into-unloaded-chunks.patch @@ -1,11 +1,11 @@ -From 3d0505501e290200e593976d9619ba105ce59ae8 Mon Sep 17 00:00:00 2001 +From 5cc6e94e8ff0ce6d1921fde051ff102140c7b0f3 Mon Sep 17 00:00:00 2001 From: Shane Freeder Date: Sun, 11 Nov 2018 21:01:09 +0000 Subject: [PATCH] Don't allow digging into unloaded chunks diff --git a/src/main/java/net/minecraft/server/PlayerConnection.java b/src/main/java/net/minecraft/server/PlayerConnection.java -index bde60377ee..b21fca9e5c 100644 +index bde60377e..b21fca9e5 100644 --- a/src/main/java/net/minecraft/server/PlayerConnection.java +++ b/src/main/java/net/minecraft/server/PlayerConnection.java @@ -1272,6 +1272,11 @@ public class PlayerConnection implements PacketListenerPlayIn { @@ -20,6 +20,26 @@ index bde60377ee..b21fca9e5c 100644 this.player.playerInteractManager.a(blockposition, packetplayinblockdig_enumplayerdigtype, packetplayinblockdig.c(), this.minecraftServer.getMaxBuildHeight());
