How should I get socket?

Hello everyone!
I wanna send and recieve some data to the client using plugin, and I should make it into AsyncPlayerPreLoginEvent handler, but I can't get Player/CraftPlayer from this event, that's why I can't get socket which server using to communicate with this client. But socket is already created, so I can't create new TCP connection for this port, it would be easier with UDP, but server using TCP.

The question is:
How can I get socket which server using to send/recieve packets for player which isn't connected yet?

 

@courage322 I'm pretty sure the socket code for Bukkit is protected. But you can mess with some packets. @mine-care loves that kind of stuff. I'm sure he can help you.

 

@bwfcwalshy Packetttyy!! #GOPACKETS!

@courage322 Please clear up what you need from packets and i will do my best to help you

 

It should be possible to obtain the connection of the player once Login Start is received by the server, however, where the server puts that connection, I am not sure.

If you get the MinecraftServer instance, something like CraftServer#getHandle() or CraftServer#getServer(), there is a private/protected field called q which is of type ServerConnection. Within this class at field h is a list of NetworkManager that handle packet stuff. You can compare each networkmanager's IP with that of the PreLoginEvent and then mess around with it (e.g. there's a channel field in NetworkManager, where you can add custom channel handlers to intercept incoming/outgoing data)

 

Or just inject your own handler into the network pipeline. Listen for the packet you need -> do what you want to do.
