Transferring variables using network library

I am making a game in which there I need several variables to be transferred from the client to the server and vice-versa.

This also involves variables located in a class.

I have made the game work in on a single project but would like to add a multiplayer.

The variables to be sent to the server is the key variable from 2 separate clients controlling different players.

xPos and yPos, xPos2, yPos2, and mode need to be sent to both clients.

Any help?

Convert JSON String to JSON Object and Parse all data ,
websocket server client setup, lib /* Websockets 0.1b Lasse Steenbock Vestergaard */
transport a JSON record

here play again to confirm:

win 10 / processing 3.5.3 /

Hi, how would I read the data and place it into variables? I get most of it but not how to read the data.


The Processing SharedCanvasClient and SharedCanvasServer examples can be adapted for this:


I just added data (1 and 2) to identify each client (1 or 2) and checked for that on server to set color of line.
