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 572b0e5911d8a7b0f3dea07301241696958d53fe..bb69775a9c96b064be24fe740b3eaa2c916a6760 100644 --- a/src/main/java/net/minecraft/server/level/ServerPlayer.java +++ b/src/main/java/net/minecraft/server/level/ServerPlayer.java @@ -314,7 +314,7 @@ public class ServerPlayer extends Player { this.stats = server.getPlayerList().getStatisticManager(this); this.advancements = server.getPlayerList().getPlayerAdvancements(this); this.maxUpStep = 1.0F; - this.fudgeSpawnLocation(world); + //this.c(worldserver); // Paper - don't move to spawn on login, only first join this.cachedSingleHashSet = new com.destroystokyo.paper.util.misc.PooledLinkedHashSets.PooledObjectLinkedOpenHashSet<>(this); // Paper @@ -533,7 +533,7 @@ 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 18dbd79b02e032e082eba3ab42c729cadee79af7..99711578f0f0281f71990a0fac0a727fdd49449f 100644 --- a/src/main/java/net/minecraft/server/players/PlayerList.java +++ b/src/main/java/net/minecraft/server/players/PlayerList.java @@ -208,6 +208,8 @@ 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";
