Is it possible to create a listener on Number object and monitor the number onChange? Something like

var listener:Object = new Object();
listener.onChange = function():Void {
    trace("number changed");
}

var myNumber:Number = new Number();
myNumber.addListener(listener);

myNumber = 5; // this will fire the on change event and trace "number changed"

Hi,

AddListener can only work for existing events

you have to use "watch" to achieve this..

here is the working sample code, open a new FLA and paste the following on first frame
-------------
var myNumber:Number = new Number();
//
valuedChanged = function (prop, oldVal, newVal)
{
      trace("number changed");
      trace("new Value is :"+newVal);
      return newVal;
};
//
this.watch("myNumber", valuedChanged);
//
myNumber = 10;
