"Ping-Pong" between client and server.

Unity Engine
1

Hi everyone! I’m quite new to unity.
I’ve got a little task and doesn’t know how to solve it. I’ve got client and server in unity - they are connected and work fine. And I need to make a ping-pong between them - I mean - client send “1” to server, server increment it by 1 and as result send to client “2”, and so on.
How to do this? ( 2 days trying to do it.

You need to use a RPC function.

@RPC
function Pong (number : int)
{
number++
networkView.RPC ("Pong", RPCMode.Others, number);
}
