Event called after the Player class for the now logged in player is created. It's the first event called after the creation of the player, before PlayerPreSpawnEvent. While this event is handled the client will see the "loading world" screen in its device, waiting for the chunks that will be sent after PlayerPreSpawnEvent (that is called by the world and every time a player changes world). That also means that this event will be called only once per player-session.
Event called when the player's language is updated (from the client or from a plugin). The old and the new languages will always be one in the server's accepted ones, as indicated in the hub's configuration file (accepted-languages field).
Event called when the player's latency is updated from the hub.
Event called when a player leaves the server, after PlayerDespawnEvent. It's the last event called for the player, after it lefts the server, and is only called once, like PlayerJoinEvent.
Event called when the player's packet loss is updated from the hub. The packet loss is only calculated for players that use a connectionless protocol like UDP (only Minecraft: Pocket Edition).
