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?  
(Will include GitHub link soon)

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

Hello,

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.
