Hi Malchom,
It seems like you're using nc.call() when you can instead be using so.send()
to send updates to the shared objects. Doing it this way means you need very
little server side code to handle updating the clients. For example, on the
client you can just do:
so.send("sharedObjectCallback", argument1, argument2...);
the server will then call all the other clients subscribed to that shared
object, calling the method sharedObjectCallback(argument1, argument2).
This can be done the way you were doing it using NetConnection.call(), but
it's just more work.
Also, you need to wait until NetConnection.connect() connects to the server
before you call SharedObject.getRemote(). You can do this by adding an event
listener on the nc object like so:
m_nc.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
function onNetStatus(e:NetStatusEvent){
so = SharedObject.getRemote();
}
