I have been using the SharedCanvasClient and SharedCavasServer to test this.
if (c.active() == false)
{
println("Client not Connected");
clientFlag = false;
}
Processing still displays all the “gobbledygook” about what happened if you can’t connect to server but you can still proceed and use the clientFlag as you wish; I used it so I would not use any of the client methods for now. I may try reconnecting to server in future exploration of this.
