Simple question about the Sharedcanvas client\server from the net examples.

Hello Guys,

I'm new to processing and having some issues with a code. I'm trying to make a simple event to 'erase' or 'clear' both client and server at the same time.

If someone could help me out that would be awesome!!

Currently, the only information sent is mouse coordinates, separated by spaces.

You can add a prefix to indicate the kind of action:

s.write("D " + pmouseX + " " + pmouseY + " " + mouseX + " " + mouseY + "\n");

(I used D as Draw, but you can use the full word or something else)

Then you will have the action in data[0], so you must use the data in the other slots:

if (data[0].equals("D"))
{
  stroke(0);
  line(data[1], data[2], data[3], data[4]);
}
else if (data[0].equals("C")) // Clear
{
   background(255); // Erase screen
}

Make an action, eg. keyPressed(), to send the "C" order, and you are done.
