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. == AT == public net.minecraft.server.level.ServerPlayer fudgeSpawnLocation(Lnet/minecraft/server/level/ServerLevel;)V diff --git a/src/main/java/net/minecraft/server/level/ServerPlayer.java b/src/main/java/net/minecraft/server/level/ServerPlayer.java index 8bb61bf4f27ad9dac6d129dc7f8154eb2e608d82..300658b41ed77c5f9403c260b6cdc62f3a323a35 100644 --- a/src/main/java/net/minecraft/server/level/ServerPlayer.java +++ b/src/main/java/net/minecraft/server/level/ServerPlayer.java @@ -328,7 +328,7 @@ 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 @@ -562,7 +562,7 @@ 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 a5e485742b10419a031b3cc48591a0bbbcab4fb5..ba0df02c2b3387b7e7698e59ce3021f1019b9a8a 100644 --- a/src/main/java/net/minecraft/server/players/PlayerList.java +++ b/src/main/java/net/minecraft/server/players/PlayerList.java @@ -222,6 +222,8 @@ 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";
