From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Spottedleaf Date: Sun, 7 Oct 2018 12:05:28 -0700 Subject: [PATCH] Add PlayerConnectionCloseEvent This event is invoked when a player has disconnected. It is guaranteed that, if the server is in online-mode, that the provided uuid and username have been validated. The event is invoked for players who have not yet logged into the world, whereas PlayerQuitEvent is only invoked on players who have logged into the world. The event is invoked for players who have already logged into the world, although whether or not the player exists in the world at the time of firing is undefined. (That is, whether the plugin can retrieve a Player object using the event parameters is undefined). However, it is guaranteed that this event is invoked AFTER PlayerQuitEvent, if the player has already logged into the world. This event is guaranteed to never fire unless AsyncPlayerPreLoginEvent has been called beforehand, and this event may not be called in parallel with AsyncPlayerPreLoginEvent for the same connection. Cancelling the AsyncPlayerPreLoginEvent guarantees the corresponding PlayerConnectionCloseEvent is never called. The event may be invoked asynchronously or synchronously. As it stands, it is never invoked asynchronously. However, plugins should check Event#isAsynchronous to be future-proof. On purpose, the deprecated PlayerPreLoginEvent event is left out of the API spec for this event. Plugins should not be using that event, and how PlayerPreLoginEvent interacts with PlayerConnectionCloseEvent is undefined. diff --git a/src/main/java/net/minecraft/network/Connection.java b/src/main/java/net/minecraft/network/Connection.java index 07fd527dd5b72ecc66311c1b81e578158e12a35c..527acbc15f3fe30541eef555480e158ab83a6130 100644 --- a/src/main/java/net/minecraft/network/Connection.java +++ b/src/main/java/net/minecraft/network/Connection.java @@ -439,6 +439,26 @@ public class Connection extends SimpleChannelInboundHandler> { this.getPacketListener().onDisconnect(Component.translatable("multiplayer.disconnect.generic")); } this.queue.clear(); // Free up packet queue. + // Paper start - Add PlayerConnectionCloseEvent + final PacketListener packetListener = this.getPacketListener(); + if (packetListener instanceof net.minecraft.server.network.ServerGamePacketListenerImpl) { + /* Player was logged in */ + final net.minecraft.server.network.ServerGamePacketListenerImpl playerConnection = (net.minecraft.server.network.ServerGamePacketListenerImpl) packetListener; + new com.destroystokyo.paper.event.player.PlayerConnectionCloseEvent(playerConnection.player.getUUID(), + playerConnection.player.getScoreboardName(), ((java.net.InetSocketAddress)address).getAddress(), false).callEvent(); + } else if (packetListener instanceof net.minecraft.server.network.ServerLoginPacketListenerImpl) { + /* Player is login stage */ + final net.minecraft.server.network.ServerLoginPacketListenerImpl loginListener = (net.minecraft.server.network.ServerLoginPacketListenerImpl) packetListener; + switch (loginListener.state) { + case READY_TO_ACCEPT: + case DELAY_ACCEPT: + case ACCEPTED: + final com.mojang.authlib.GameProfile profile = loginListener.gameProfile; /* Should be non-null at this stage */ + new com.destroystokyo.paper.event.player.PlayerConnectionCloseEvent(profile.getId(), profile.getName(), + ((java.net.InetSocketAddress)address).getAddress(), false).callEvent(); + } + } + // Paper end } }
