|
|
// - LoginPacket, for cache player info. The player info will be stored in [Player.PlayerInfo].
|
|
// - KeepAlivePacket, for avoid the client to be kicked by the server.
|
|
// - PlayerPosition, is only received when server teleporting the player. And the confirm packet is automatically sent.
|
|
// - Respawn, for updating player info, which may change when player respawned.
|
|
//
|
|
