Dynamic naming or whatever it's called

[dogcollarlabor]

Hi all, first time posting, long time lurker. Thanks for the great forum.

I'm curious if there is dynamic naming for variables, arrays, functions and whatnot in AS3. Below are Perl examples of what I'm asking about. It should be pretty explanatory.

Thanks again,
Doug

$varOne = 'dog';
$varTwo = 'cat';

@arrayOne = ('dog','cat');
@arrayTwo = ('fish','frog');

sub subOne { print "anything"; }
sub subTwo { print "anything else"; }

$varDyn = 'One';

print ${'var'.$varDyn};
#result = dog

&{'sub'.$varDyn};
#result = anything

print ${'array'.$varDyn}[1];
#result = cat

${'varTest'} = 'bird';
print $varTest;
#result = bird

hi,

In ActionScript you have array notation:

var myString:String = "my";

var myVar:String = "dog";
trace (this[myString+"Var"]); // dog

var myArray:Array = new Array("cat", "dog");
trace (this[myString+"Array"][0]); // cat

function myFunction():void
{
    trace ("myFunction called");
}

this[myString + "Function"](); // myFunction called

If you have a DisplayObject on the stage, you can also use getChildByName():

var myString:String = "some";

var mySprite:Sprite = new Sprite();
mySprite.name = "someName";
addChild(mySprite);

trace(getChildByName(myString+"Name")); // [object Sprite]

Thanks a bunch nunomira, that will help a lot.
