Hey Victor I like your solution thanks :)
Romu, I'll check out your method when I get a little time, I have to
get this working quickly so the dirty method will do for now.
Thanks everyone!

If you fell developing it, I wrote an experiment about the flash proxy
class. I would do it that way. The proxy class makes you able to
handle new
methods and properties on any other classes (especially the one
that are not
dynamic, almost all of them), to access to something like:
mySprite.myNewProperty
mySprite.myNewMethod
In my example I proxy an array but you could do it for anything.

Make a search on Google with the keywords as3, proxy and dot syntax
maybe
someone has already done that.
Hope it helps.

Subject: Re: [Flashcoders] AS3: How can I target an object from
adot-sytaxstring?
One dirty way would be like this:
var sTarget:String = "first.second.third.fourth";
var aTarget:Array = sTarget.split(".");
var mcTarget = this[ aTarget[0] ];
for (var i:int = 1; i < aTarget.length; i += 1)
{
mcTarget = mcTarget[ aTarget[i] ];
}
trace( mcTarget );

Hmmm, can anyone suggest the completed code? I can't see how this
would
work as you are returning a class reference that is named after
the root
object. Maybe I am missing something.
Any suggestions much appreciated to keep me out of a long-hand switch
statement :)

Hello, I'm being passed a string that has a reference to an
object in
dot-syntax like this: "myOb.property.property2.property3"
The object targeted may be a varying number of levels inside of the
top-level object.
I have tried to write this by turning the string into an array and
then creating the object but I'm not sure how:
public static function arToObj(a:Array):Object
{
var retObj:Object;
for ( var i:Number=0; i<a.length; i++ ) {
if (i==a.length-1){
//dont know what to do
here !!
}
};
return retObj;
}
This is untested e-mail ActionScript, but you could do something
like
this:
public static function arToObj(a:String):Object
{
var strArray:Array;
var clsRef:Class;
strArray = a.split(".");
clsRef = getDefinitionByName(strArray[0]) as Class;
return new clsRef();
}
I'm sure there are bugs in there, but that's the basic approach I'd
take.
Cordially,
Kerry Thompson
