This change will ensure every plugin +receives a deterministic result, and should no longer require 1 tick +delays anymore. + +== AT == +public net.minecraft.server.level.ChunkMap addEntity(Lnet/minecraft/world/entity/Entity;)V + +diff --git a/src/main/java/net/minecraft/server/level/ChunkMap.java b/src/main/java/net/minecraft/server/level/ChunkMap.java +index 914e9e0af7533cbf487ea0413da447d5eb8d527b..69f54e812794b23e5f54606da86f71163f5f0bbe 100644 +--- a/src/main/java/net/minecraft/server/level/ChunkMap.java ++++ b/src/main/java/net/minecraft/server/level/ChunkMap.java +@@ -1299,6 +1299,7 @@ public class ChunkMap extends ChunkStorage implements ChunkHolder.PlayerProvider + return; + } + // Paper end - ignore and warn about illegal addEntity calls instead of crashing server ++ if (entity instanceof ServerPlayer && ((ServerPlayer) entity).supressTrackerForLogin) return; // Paper - Fire PlayerJoinEvent when Player is actually ready; Delay adding to tracker until after list packets + if (!(entity instanceof EnderDragonPart)) { + EntityType<?> entitytypes = entity.getType(); + int i = entitytypes.clientTrackingRange() * 16; +diff --git a/src/main/java/net/minecraft/server/level/ServerPlayer.java b/src/main/java/net/minecraft/server/level/ServerPlayer.java +index eebf44c7124c4f48b6d48562a00633b1e8ff9b00..8c80a852ed00c2bf79bb68da9d535af425893deb 100644 +--- a/src/main/java/net/minecraft/server/level/ServerPlayer.java ++++ b/src/main/java/net/minecraft/server/level/ServerPlayer.java +@@ -317,6 +317,7 @@ public class ServerPlayer extends net.minecraft.world.entity.player.Player { + public double maxHealthCache; + public boolean joining = true; + public boolean sentListPacket = false; ++ public boolean supressTrackerForLogin = false; // Paper - Fire PlayerJoinEvent when Player is actually ready + public String kickLeaveMessage = null; // SPIGOT-3034: Forward leave message to PlayerQuitEvent + // CraftBukkit end + public boolean isRealPlayer; // Paper +diff --git a/src/main/java/net/minecraft/server/players/PlayerList.java b/src/main/java/net/minecraft/server/players/PlayerList.java +index e137278f9dc02eefaaf7071a3219436a94cfcfac..ac5725230b04bc1a333863e251fe86580f909ea9 100644 +--- a/src/main/java/net/minecraft/server/players/PlayerList.java ++++ b/src/main/java/net/minecraft/server/players/PlayerList.java +@@ -299,6 +299,13 @@ public abstract class PlayerList { + this.playersByUUID.put(player.getUUID(), player); + // this.broadcastAll(ClientboundPlayerInfoUpdatePacket.createPlayerInitializing(List.of(entityplayer))); // CraftBukkit - replaced with loop below + ++ // Paper start - Fire PlayerJoinEvent when Player is actually ready; correctly register player BEFORE PlayerJoinEvent, so the entity is valid and doesn't require tick delay hacks ++ player.supressTrackerForLogin = true; ++ worldserver1.addNewPlayer(player); ++ this.server.getCustomBossEvents().onPlayerConnect(player); // see commented out section below worldserver.addPlayerJoin(entityplayer); ++ player.loadAndSpawnEnderpearls(optional); ++ player.loadAndSpawnParentVehicle(optional); ++ // Paper end - Fire PlayerJoinEvent when Player is actually ready + // CraftBukkit start + CraftPlayer bukkitPlayer = player.getBukkitEntity(); + +@@ -337,6 +344,8 @@ public abstract class PlayerList { + player.connection.send(ClientboundPlayerInfoUpdatePacket.createPlayerInitializing(List.of(entityplayer1))); + } + player.sentListPacket = true; ++ player.supressTrackerForLogin = false; // Paper - Fire PlayerJoinEvent when Player is actually ready ++ ((ServerLevel)player.level()).getChunkSource().chunkMap.addEntity(player); // Paper - Fire PlayerJoinEvent when Player is actually ready; track entity now + // CraftBukkit end + + player.refreshEntityData(player); // CraftBukkit - BungeeCord#2321, send complete data to self on spawn +@@ -352,8 +361,7 @@ public abstract class PlayerList { + worldserver1 = player.serverLevel(); // CraftBukkit - Update in case join event changed it + // CraftBukkit end + this.sendActivePlayerEffects(player); +- player.loadAndSpawnEnderpearls(optional); +- player.loadAndSpawnParentVehicle(optional); ++ // Paper - move loading pearls / parent vehicle up + player.initInventoryMenu(); + // CraftBukkit - Moved from above, added world + // Paper start - Configurable player collision; Add to collideRule team if needed |
