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 1d322c8d7e072cea923edcb92e28fa82de8daba8..e8a1aff3ddd94925e1c0f554cc8e7ff9e9864242 100644 --- a/src/main/java/net/minecraft/server/level/ServerPlayer.java +++ b/src/main/java/net/minecraft/server/level/ServerPlayer.java @@ -377,7 +377,7 @@ 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 @@ -611,7 +611,7 @@ public class ServerPlayer extends Player { position = Vec3.atCenterOf(world.getSharedSpawnPos()); } this.setLevel(world); - this.setPos(position); + 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 16982a16639a07e31456aa1e27c1058fbf9519ac..47f810e7be3fb7a1233a260fec456b8f65f9a9e2 100644 --- a/src/main/java/net/minecraft/server/players/PlayerList.java +++ b/src/main/java/net/minecraft/server/players/PlayerList.java @@ -236,6 +236,7 @@ public abstract class PlayerList { // Paper start 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 end player.setServerLevel(worldserver1);
