Now we have a program that is going to handle the connections and pass the data around each
connected user.
Creating the Flash application
Open the project ‘Examples\Chapter22\MoveBox.fla’. The code in frame 1 is as follows:
sock = new XMLSocket();
sock.onXML = gotMessage;
sock.onConnect = onSockConnect;
usedids = new Array(0, 0, 0, 0, 0, 0, 0, 0);
dragbox = 0;
sock.connect("192.168.0.1", 5001)
stop ();
The root level variable ‘sock’ is set as a new XML Socket object and the two callback functions for
this object ‘onXML’ and ‘onConnect’ are set to ‘gotMessage’ and ‘onSockConnect’ respectively.
The ‘onSockConnect’ function gets called when a connection is made and is passed a Boolean
variable that indicates whether the connection was successfully made. The XMLSocket member
