Client-Side ActionScript Language Reference

To minimize network traffic, this method is not called when a client “changes” a property to
the same value it currently has. That is, if a property is set to the same value multiple times in
a row, this method is invoked the first time the property is set, but not during subsequent
settings, as shown in the following example:

my_so.data.x = 15;
// The following line invokes onSync.
my_so.data.x = 20;
/* The following line doesn’t invoke onSync,
even if issued by a different client. */
my_so.data.x = 20;

Example

The following examples creates or gets a remote shared object named

position

var myRemote_so:SharedObject = SharedObject.getRemote("position",

my_nc.uri, false);

The following updates the ball position when another participant moves the ball;

sharedBall_mc

is a movie clip on the Stage:

myRemote_so.onSync = function(list) {

sharedBall_mc._x= myRemote_so.data.x;
sharedBall_mc._y= myRemote_so.data.y;

}

/* You must always call connect() in order to successfully
connect to the shared object and share data. */
myRemote_so.connect(my_nc);
