From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Thu, 9 Apr 2020 21:20:33 -0400 Subject: [PATCH] Don't move existing players to world spawn This can cause a nasty server lag the spawn chunks are not kept loaded or they aren't finished loading yet, or if the world spawn radius is larger than the keep loaded range. By skipping this, we avoid potential for a large spike on server start. diff --git a/src/main/java/net/minecraft/server/level/ServerPlayer.java b/src/main/java/net/minecraft/server/level/ServerPlayer.java index fd609c7b757b570206c17444867f786c1767aa69..d507adcb538933fcf36e9a4bfb561106d509c26f 100644 --- a/src/main/java/net/minecraft/server/level/ServerPlayer.java +++ b/src/main/java/net/minecraft/server/level/ServerPlayer.java @@ -313,7 +313,7 @@ public class ServerPlayer extends Player { this.stats = server.getPlayerList().getPlayerStats(this); this.advancements = server.getPlayerList().getPlayerAdvancements(this); this.maxUpStep = 1.0F; - this.fudgeSpawnLocation(world); + //this.fudgeSpawnLocation(world); // Paper - don't move to spawn on login, only first join this.cachedSingleHashSet = new com.destroystokyo.paper.util.misc.PooledLinkedHashSets.PooledObjectLinkedOpenHashSet<>(this); // Paper @@ -531,7 +531,7 @@ public class ServerPlayer extends Player { position = Vec3.atCenterOf(((ServerLevel) world).getSharedSpawnPos()); } this.level = world; - this.setPos(position.x(), position.y(), position.z()); + this.setPosRaw(position.x(), position.y(), position.z()); // Paper - don't register to chunks yet } this.gameMode.setLevel((ServerLevel) world); } diff --git a/src/main/java/net/minecraft/server/players/PlayerList.java b/src/main/java/net/minecraft/server/players/PlayerList.java index 33b607227718e08f26d7ab5744bbbff806f33366..e1d729d86d11f9bc9452b7382f12aeb668c19936 100644 --- a/src/main/java/net/minecraft/server/players/PlayerList.java +++ b/src/main/java/net/minecraft/server/players/PlayerList.java @@ -210,6 +210,8 @@ public abstract class PlayerList { worldserver1 = worldserver; } + if (nbttagcompound == null) player.fudgeSpawnLocation(worldserver1); // Paper - only move to spawn on first login, otherwise, stay where you are.... + player.setLevel(worldserver1); String s1 = "local";
