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 52ee3440b09b227bf1f488f374a0e282690f6ba4..007513080938a8d0cf43c050ef4e1132a939918c 100644 --- a/src/main/java/net/minecraft/server/level/ServerPlayer.java +++ b/src/main/java/net/minecraft/server/level/ServerPlayer.java @@ -334,7 +334,7 @@ public class ServerPlayer extends Player { this.stats = server.getPlayerList().getPlayerStats(this); this.advancements = server.getPlayerList().getPlayerAdvancements(this); this.setMaxUpStep(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 @@ -568,7 +568,7 @@ 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 56a8c90d3bf0e860acbabcd45957f51f8431317f..ac8882d0d2939bd6e59dc4e08bc1efc88a580360 100644 --- a/src/main/java/net/minecraft/server/players/PlayerList.java +++ b/src/main/java/net/minecraft/server/players/PlayerList.java @@ -226,6 +226,7 @@ public abstract class PlayerList { // Paper if (nbttagcompound == null) { player.spawnReason = org.bukkit.event.entity.CreatureSpawnEvent.SpawnReason.DEFAULT; // set Player SpawnReason to DEFAULT on first login + player.fudgeSpawnLocation(worldserver1); // only move to spawn on first login, otherwise, stay where you are.... } // Paper player.setLevel(worldserver1);
