Sending/Receiving Packets from TileEntity/GUI

[BURN447]

How would I go about interfacing between a button clicked between my GUI and Tile entity? I know it has to do with Packets, but I'm not sure how to send/receive those packets on either end.

This shows me how to create the bare bones implementation, but there isn't anything pertaining to how to use it in the slightest, or if there is, it doesn't make any sense to me, at least to a tileEntity, because I can see how to send something to a server, but I can't tell how to read it or even receive it.

When the button is clicked -> send a packet to the server with the relevant information (TE's pos, what button was clicked).

Server gets the packet, reads the data, gets the TileEntity from the position encoded in the packet, and does things (if valid to perform).

How would I interpret what is happening in the tileEntity itself? I'm assuming it has to do with the onDataPacket function

You want to know what data the TE has?

Yes, you override those three methods. Yes there are three.

getDataPacket: sending

getUpdateTag: sending

onDataPacket: recieving

I'm actually trying to send a packet from the client that a button was clicked, and if so, start a process on the server, which would then set the variable on both ends back to false until the button is clicked again. But this is starting to make sense, and I think I might be able to figure it out. I'm thinking that I'd use pkt.readInt and then send one back setting the variable back to false.

I'm not sure if this is the best implementation, but I did it like so:

 

In the GUI class, when the button is pressed (checked with actionPerformed) you use your packet handler to send to server a custom message with the information you need. When the message is sent to the server, you can set the variable on the server side with a handler. Then inside the server handler you can send a packet to players.
