Hey everyone!  
I just got a little question for you. Right now I work for a project where I have to connect two Processing sketches on two computers, to send an integer between those two computers. I still found some libraries like [processing.net](http://processing.net) or the OOCSI library. Unfortunately I did not found a solution to connection two sketches on different computers with these libraries. I just can connect two sketches on one single computer.  
Maybe some of you have an idea, how to solve my problem.

Thanks,  
Felix

If you have `processing.net` library¸you should also have File\>Examples\>Libraries\>Network\>SharedCanvasClient and SharedCanvasServer examples. I suggest you to get these working between computers, then base your code on them.

Also, where are these computers located in relation to each other? In a single LAN network or across a globe?

Thanks for your quick reply!  
Both computer are connected at the same WLAN network. Do I have to connect both at the network enviroment?

I don’t think so. I think it’s enough as it is - just make sure to find out server’s IP in that WLAN network, and dial  
that into the client, and I think it should work.

(yeah, not so quick reply now… .\_.)

I made pong using [processing.net](http://processing.net) a while back. It lags a bit, but here is the code:

It’s a bit messy, but it works.
