Flash Banners Click tag info wars AS2 or 3

Question

I do a lot of Flash banners for clients, I have a situation where I had a client send me this article
http://www.flashclicktag.com/
and tell me that I should not be using Flash for banners in AS3.
I have click or clikTag info for AS2 and 3
AS2
on (release) {
if (_root.clickTAG.substr(0,5) == "http:") {
getURL(_root.clickTAG, "_blank");
CLICK TAG AS 3.0
myButton.addEventListener(  MouseEvent.CLICK, 
function():void { 
if (root.loaderInfo.parameters.clickTAG.substr(0,5)=="http:") { 
navigateToURL( 
new URLRequest(root.loaderInfo.parameters.clickTAG), 
"_blank" 
I even have the click tag code for Google Ad serve which just replaces the & with~
ButtonName.addEventListener(MouseEvent.CLICK, functionName)
function functionName(event:MouseEvent) : void
     if (root.loaderInfo.parameters.clickTAG.substr(0, 5) == "http:")
         Url = String(root.loaderInfo.parameters.clickTAG).split
("~").join("&");
         navigateToURL(new URLRequest(Url), "_blank");
     }// end if[/code]
In an honest opinion which format should I use? as I don't need to do double the work to re do from AS3 to AS2. Obviously some as services will only allow AS2 for clickTag info.
any help?

Answer 1

I'm in the same position, just starting to move from
intermediate comfort with AS2 to a fresh beginning with AS3...not
so easy for a guy who has so little logical thinking that I failed
algebra in high school! I too am a bit annoyed by all the extra
steps involved, such as having to add EventListeners for mouse
events, when these really ought to be simplified and there by
default, like in AS2. For example, why can't onMouseDown remain as
a built-in behavior rather than having to take up 2 lines of code
to insert it each and every time now?
On the other hand, I am delighted at the way a lot of the
inconsistencies in AS2 have been gotten rid of. No more having to
remember when to put .x and when ._x, and so on. And now that I'm
finally starting to learn how to use external classes, I see the
beauty in it, and AS3 is custom-made for this. It seems that if you
ever want to really advance in ActionScript programming, you need
to start working with creating your own classes, and as long as
you're going to learn those from scratch, may as well learn it in
AS3.
Putting AS on buttons was outdated practice years ago. It
makes much greater sense to place all script on the timeline, with
comments to separate it. Try programming the simplest game where
objects are moving around and colliding, all controlled by script,
and then a couple coded buttons control them. Bugs are inevitable,
and debugging script when it's partly on the timeline, some is
attached to main movie buttons, and some attached to movie clips
inside movie clips, is a nightmare. Once you do scripting on the
timeline, you'll never want to go back to the crude practice of
attaching script to objects.
Overall, it's a steeper climb than I'd have liked, to upgrade
my knowledge from AS2 to AS3. But ultimately I think it's the best
idea.
