Migrate existing code of AS3 to AS2 - URLRequest, URLLoader

Hi,
I have written code to read an XML file by using URLRequest and URLLoader in ActionScript 3.0. Code is pasted below. This runs well in AS3. Problem I am facing is because I wrote this in AS3, I am not able to use the DateChooser component in another part of the flash module because it seems like DateChooser component is not supported in AS3. So I want to migrate my below AS3 code back to AS2.
**** Code in AS3 (I need help in writing equivalent code in AS2) :-
var xmlText:XML ;
var xmlReq:URLRequest = new URLRequest("myFile.xml");
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.load(xmlReq);
xmlLoader.addEventListener(Event.COMPLETE,xmlLoaded);
function xmlLoaded(event:Event):void
xmlText = new XML(xmlLoader.data);
info_txt.htmlText = xmlText.someTag ;
**** I cannot use the above as is because, when I change the publish settings from AS3 to AS2, I get following errors -
The class or interface 'URLRequest' could not be loaded.
The class or interface 'URLLoader' could not be loaded.
The class or interface 'Event' could not be loaded.
Same works well in AS3. What should I do to make this work in AS2 or can anyone direct me in writing an equivalent in AS2.
Please assist.
Thanks in advance.

parsing is done using the xmlnode methods and properties. how you parse an xml file (in as2) depends on its structure. but generally, you use firstChild, nextSibling, childNodes and nodeValue in the appropriate sequence to extact data. the flash help files have sample code. for tutorials, check google.
if you're trying to load a cross-domain xml file, you'll have a cross-domain security issue to deal with.

How do you convert this code from AS3 to AS2?

Hi,
I created some AS3 code that is working perfectly for us.
However now we need to convert it to AS2 so that it can be Flash
Player 8 compatible. If it could also be compatible for Flash
Player 7 that would be ideal but not a requirement.
Thanks in advance.

Are you wanting someone to do the conversion for you, or are
you asking for general tips for doing the conversion yourself?
i can give you tips:
have a look at the
ActionScript
2.0 Migration page.
In this you'll find the property conversions eg(going from
AS3 to AS2). y becomes _y, height becomes _height, scaleX becomes
_xscale, void becomes Void etc.
you'll find that events need to be converted, eg.
particle.addEventListener(Event.ENTER_FRAME,
animateParticle);
becomes:
particle.onEnterFrame=animateParticle;
the onEnterFrame class doesn't pass an Event parameter to the
event listener. Instead, the event listener is automatically in the
scope of the event dispatcher, so instead of 'event.target' you
will be able to just target 'this'.
You'll need to use setInterval() instead of the Timer class.
You'll need to use attachMovie() instead of
addChild().

How would I pass a variable from flash to php?
I've been in many tutorials in the net but I cannot understand much of the tutorials...
I only saw same method like using URLRequest & URLLoader with the location of the php files then the variables in the php which connects to the database is accessible.
All are accessing the php not passing flash variables to the php file like in the above code.
All help is greatly appreciated.

that's really poor as2 coding so it will translate to really poor as3 coding.
but, to answer your question, you assign a data property to your urlrequest to convey data from flash to php. the data property will be a urlvariables instance and you assign variables/values to your urlvariables instance:
var urlVar:URLVariables=new URLVariables();
urlVar.eid=whatevervalue;
urlVar.rdoc=whatever;
urlVar.str=whateverelse;
yourURLRequest.data=urlVar;

Migrating AS2 Code to AS3

ORIGINAL AS1 SCRIPT
I have already tried several ways to migrate this code, but I
get unexpected behaviors. Can any one help me?
The volume control on the stage is made out of two
movieClips: one called knob and the other volume_track over which
the knob slides (is dragged by user) This two Clips are turned into
one movieClip called volume_control. The Sound Object is within an
Empty MovieClip called soundMc. the pos variable gathers the knob's
position on the volume_track.
The following code is the original one, which works
perfectly.

Hi, Kglad,
I had made a mistake, that's why the code didn't work at all.
My bad.
I modified a little the code you suggested as well as the
Clips Instance Names.
I used the Rectangle Class to get the
startDrag(lockCenter:Boolean = false, bounds:Rectangle = null)
method's bound argument. This is how the Rectangle is set up:
Rectangle(x:Number, y:Number, width:Number, height:Number);
It works now, but there's a couple of unexpected things
happening.
1. It really hard to make the knob move left and right
because the cursor seems not to get a firm hold of it.
2. Once it starts dragging, I have to move it very slowly
otherwise I lose a hold on the knob.
3 - In order to get the knob to drag within the bounderies of
its track, I had to add extra numbers in the x (8 instead of 0),
width (a -12), and height (0 instead of e.currentTarget.y), but
this poses a problem later when I try to get a definite value to
control the volume intensity between 0.0 (Minimum volume) and 1.0
(Max Vol). Tracing pos, I got these results:
Min pos: 0.10810810810810811
Max pos: 0.9459459459459459
Is there a way to clean up those results, like a Math
function, so that I can get something like this 0.1 and 0.9 instead
of those long numbers?
volume_control.volKnob.addEventListener(MouseEvent.MOUSE_DOWN,
dragKnob);
volume_control.volKnob.addEventListener(MouseEvent.MOUSE_UP,
stopKnob);
volume_control.volKnob.addEventListener(MouseEvent.MOUSE_OUT,
stopKnob);
var t:Timer=new Timer(70,0);
t.addEventListener(TimerEvent.TIMER,volF);
function dragKnob(e:MouseEvent) {
trace("Begin dragging");
var rect:Rectangle = new Rectangle(8, e.currentTarget.y,
e.currentTarget.parent.volTrack.width-12, 0);
e.currentTarget.startDrag(false, rect);
t.start();
function stopKnob(e:MouseEvent) {
trace("Stop draggin");
e.currentTarget.stopDrag();
t.stop();
function volF(e:TimerEvent) {
var pos:Number =
(volume_control.volKnob.x/volume_control.volTrack.width);
//soundObjChannel.soundTransform.volume =pos; // you need to
define your soundChannel object whereever you're applying the play
method to your sound object
trace("pos" + pos);

Dummy Guide needed for converting AS2 code into AS3

I have to convert my existing AS2 code into AS3, but I might as well be reading chinese. I never even began to learn AS3, it was still fairly new at the time and the class ended before we had an opportunity to even touch on it. My major was not web design, it was the print side of design. I took an additional class, after I graduated, to learn web design and our teacher told us, basically, that we were designers, not coders so we won't be getting much into actionscripting, beyond the basics. At the time I was relieved, but looking back, I really wish we would have gotten more into it. Bottom line, I need to learn now.
Is there ANYONE that can help me out? I will list my code below, buy I am way beyond lost any help that can be provided, I would be so grateful!!!!
On the main timeline I have the basic..
stop(); -- I found the AS3 version, but I don't know what I'm looking at. I get "not_yet_set.stop()" and there are are 8 options I can choose from. I just want the timeline to stop until I tell it where to go next. And what is "not_yet_set"
Then I have my buttons, which are, basically...
on (release) {
gotoAndStop("Home");
Or "gotoAndPlay("Whatever");"
I also have buttons for scrolling...
on (press) {
play();
on (release) {
stop();
AND
on (press) {
_root.AboutMe_Controller.gotoAndPlay(…
on (release) {
_root.AboutMe_Controller.gotoAndStop(…
For the on(release) command, this is what I found as the AS3 version: not_set_yet.dispatchEvent()

because that's really as1 code, you have steeper learning curve than going from as2 to as3.
first, remove all code from objects, assign instance names to your buttons and you can then start on as3:
// so, if you name your home button, home_btn:
home_btn.addEventListener(MouseEvent.CLICK,homeF);
function homeF(e:MouseEvent):void{
gotoAndStop("Home");
p.s. the not_yet_set stuff is there because you tried to use script assist or some other actionscript shortcut.

Help! Convert simple Flash AS2 code to AS3

Hi everyone,
I'm a Flash beginner and followed a tutorial: http://www.webwasp.co.uk/tutorials/018/tutorial.php ... to learn how to make a "live paint/draw" effect. I didn't realize that if I made something in AS2, I wouldn't be able to embed it (and have it work) into my root AS3 file, where I've got a bunch of other stuff going on. I've tried following tips on how to change AS2 code to AS3, but it just doesn't work. I know it's simple code, and that some genius out there can figure it out, but I'm at a loss. Please help!
Here's the AS2 code:
_root.createEmptyMovieClip("myLine", 0);
_root.onMouseDown = function() {
   myLine.moveTo(_xmouse, _ymouse);
   ranWidth = Math.round((Math.random() * 10)+2);
   myLine.lineStyle(ranWidth, 0xff0000, 100);
   _root.onMouseMove = function() {
      myLine.lineTo(_xmouse, _ymouse);
_root.onMouseUp = function() {
   _root.onMouseMove = noLine;
Thanks in advance!
Signed,
Nicolle
Flash Desperado

Considering the code is on timeline:
var myLine:Sprite = new Sprite();
addChild(myLine);
var g:Graphics = myLine.graphics;
addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown);
function onMouseDown(e:MouseEvent):void {
     var ranWidth:Number = Math.round((Math.random() * 10) + 2);
     g.clear();
     g.lineStyle(ranWidth, 0xFF0000, 1);
     addEventListener(MouseEvent.MOUSE_MOVE, onMouseMove);
     addEventListener(MouseEvent.MOUSE_UP, onMouseUp);
function onMouseMove(e:MouseEvent):void {
     g.lineTo(mouseX, mouseY);
function onMouseUp(e:MouseEvent):void {
     removeEventListener(MouseEvent.MOUSE_MOVE, onMouseMove);
     removeEventListener(MouseEvent.MOUSE_UP, onMouseUp);

Change as2 code to as3

I used a tutorial http://www.flash-game-design.com/flash-tutorials/funky-flash-website-tutorial-5.html to make a menu for my application, I've tried following tips on how to change AS2 code to AS3, but it just doesn't work.
menu = ["bulls", "about", "roster", "schedule"];
var current = menu[0];
for (var i = 0; i<menu.length; i++) {
var b = menu[i];
this[b+"_btn"].stars._visible = false;
this[b+"_btn"].txt = b;
this[b+"_btn"].onPress = function() {
_root.site[current+"_btn"].stars._visible = false;
_root.site[this.txt+"_btn"].stars._visible = true;
current = this.txt;
_root.site.content.gotoAndStop(this.txt)
this[current+"btn"].stars._visible = true;
this.onEnterFrame = function() {
this[current+"_btn"].stars.s1._rotation += 1;
this[current+"_btn"].stars.s2._rotation += 0.5;
Thank you,
Glenn

Just a note. Function declarations in a loop is an EXTREMELY bad practice that will lead to many problems if it doesn't have some already. So, the following lines:
for (var i:int = 0; i<menu.length; i++) {
    var b:String = menu[i];
    this[b+"_btn"].stars.visible = false;
    this[b+"_btn"].addEventListener(MouseEvent.CLICK,fn);
    this[b+"_btn"].txt=b;
    function fn(e:MouseEvent):void{
        this[current].stars.visible = false;
        var nam:String=e.target.parent.name;
        this[nam].stars.visible = true;
        current = nam;
        //MovieClip(root).site.content.gotoAndStop(this.txt)
should be:
for (var i:int = 0; i < menu.length; i++) {
     var b:String = menu[i];
     this[b+"_btn"].stars.visible = false;
     this[b+"_btn"].addEventListener(MouseEvent.CLICK,fn);
     this[b+"_btn"].txt=b;
function fn(e:MouseEvent):void {
     this[current].stars.visible = false;
     var nam:String=e.target.parent.name;
     this[nam].stars.visible = true;
     current = nam;
     //MovieClip(root).site.content.gotoAndStop(this.txt)

AS3 centering and resizing a background in existing code

I have a code for a page I am using and I would like to add a background and have it resize with the screen like the rest of the page. I have created a movie button named "pic" with the image in it but I don't know how to write the code and place it in the existing AS3 code file. Could someone please help. I am brand new to this so if someone could tell me how to place the code like i was in 3rd grade, that would be great. Here is the existing code.

1.download flashdevelop (Flash has bad code hinting and error descriptions)
2.start with deleting underscores in _root,_x,_y
3.work your way up from there
4.Lines like:
this.onPress=function
are probably attached directly to a button or MovieClip: This is not possible in as3 anymore. You have to take the code out of the button and put it on the timeline of the button, if it is a MovieClip.
5.The Event Model has changed considerably:
onEnterFrame=function(){
// do stuff here
is now
addEventListener(ENTER_FRAME, enterFrameHandler);
function enterFrameHandler(e:Event):void{
//do stuff here

Converting AS3 to AS2

Does anyone know how to translate this code into AS2? My client can't support AS3.
var exitTimer:Timer = new Timer(15000, 1);
exitTimer.addListener(TimerEvent.TIMER, jump);
function jump(event:TimerEvent):void {
gotoAndStop("Scene 1")
exitTimer.start();
Thank you!

I put the wrong script in. This is the one I'm trying to convert from AS3 to AS2. Do I still use the setTimeout function or is the getTimer function more appropriate?
var exitTimer:Timer = new Timer(15000, 1);
exitTimer.addListener(TimerEvent.TIMER, jump);
function jump(event:TimerEvent):void {
navigateToURL(new URLRequest("http://www.url.com"));
exitTimer.start();

Migrating existing portable homes to new server

aside from moving the homedir data from the old server to the new, there seem to be at least a few issues with migrating existing portable home accounts to a new server:
1. some of users' account details, like GeneratedUID, authentication authority, kerberos principals, OriginalNFSHomeDirectory, are different, while others (name, shortname, UID, GID, etc.) remain the same.
2. home directory (OriginalNFSHomeDirectory, etc.) point to the old server.
3. there's data on local machines that we don't sync back to the server, so we can't just blow away the existing local accounts and start fresh.
the quickest way to migrate these users to the new server (with all the same shortnames and UIDs, etc.) seems to be to remove the local cached accounts (leaving the home folders) and have them recreate new PHDs on login, syncing things back down to the original home folder. i'm guess this won't involve much syncing, it's all the same data, essentially.
the other way i can see resolving this is to replace the account attributes for each client to match what they should be when pointed to the new server. this would involve scripting the process for reliability and not moving any data or deleting accounts, but it will take more testing on my part.
what do you think? can you think of better ways to accomplish this task?
summary: what's the best way to move existing portable home accounts bound to "Server A" to "Server B," while maintaining data and portable homes pointed to the new server and storage?
thanks.

that createmobileaccount syntax was wrong. i guess you don't need the -t option and can instead specify the whole path to the user's home. it seems to work well enough, creating a portable home with no default sync settings -- basically manual. for my needs that's fine. the sync settings are managed via mcx anyway.
here's an updated version of the standalone script. i realized just now the script assumes the diradmin usernames and passwords are the same between servers. if that's not the case, you can hard code it or add a couple of variables. since they're just taken in order on stdin, add them in order. i should also add a function to interactively ask for the passwords with stty -echo to avoid having the passes logged in command history or allowing the script to curl the pass from another file on a web server or something. for now, this seems to work for my purposes. edit as you see fit.

I have been asked whether it would be feasable to translate Java code to AS3. This is a bit difficult since I am not really an expert in Java and only a beginner wrt AS3. Looking at some code samples it seems doable (at least in principle), but of course there might be hidden gotchas lurking. Hence:
- Are there Java features which do not have an equivalent in AS3?
- Does AS3 have prerequisites which do not exist in Java?
- Other aspects to consider?
Any comment or advice will be greatly appreciated.
Best regards
H.

Thanks to you all.
In the meantime I read "Actionscript for Java developers"
http://www.javaworld.com/javaworld/jw-02-2009/jw-02-actionscript1.html
and it seems like the two languages are not too far apart.
Of course there are differences, but we only need to consider those features which Java has and AS has not (like method overloading) and modify our Java sources to not use these. Since the goal is not to have a universal tool which translates _any_ kind of Java source to AS but only our specific code base I think it will be worth a small effort to test how far we get with a machine translation.
Yes, libraries may well be an issue - but again, I would have to see which (library) functions are actually used and how to replace them.
Thanks again and best regards
H.

Can AS1 code call AS3 code?

I was wondering if there was any way for AS1 code to call AS3
code.
I need to write a server extension for SmartFox Pro. I just
found out that the only version of action script that SmartFox
sever extensions can be written in is AS1. However, I have a bunch
of code already written in AS3 that I need to use. I have all of
the source for the AS3 code.
Is there a way for me to use my existing code, or am I out of
luck?
Thanks in advance
John Lawrie

you may be able to use swfbridge to do so, basically
implementing the LocalConnection class

How to add observable behaviour in existing code?

Hi everyone, I'm new to design patterns. I have an existing numerical analysis package that I use to find roots using multiple strategy (bisection, secant, newton, etc). I want to show the process of root finding for every iterations taken by the algorithm (for example, iteration 0: left = 0, mid = 0.5, right = 1; iteration 2: left = 0, mid = 0.25, right = 0.5; ... etc. Its not exactly like that, I want to show it graphically, but you see what I mean). Looks like I need Observer to add event handling to notify the change of state in each initial guess as well as signaling the event when a root is/isn't found. But the solver classes doesn't seem to be implementing Observable, they just give out the answer, or not. How do I add Observer pattern without modifying the original code? I thought about using Decorator and having the real solver do the root finding but it just doesn't make sense to me. Thanx in advance.

That won't get you intermediate results, though.If the method being observed needs to be firing multiple events per invocation, no, it won't.
@OP, you were on the right track with the decorator pattern (indeed, that could be just as appropriate). What made you think it was wrong?I think that's the OP's tripping point:

...But the solver classes doesn't seem to be implementing Observable, they just give out the answer, or not.
Aha. Bytecode weaving (or plain old decompiling and nicking the source) then.Nope, I didn't. You're just too damned fast!For my own good! I hit "post" and immediately go "I forgot to say X" :-/
@OP: if you want to see some examples of using bytecode weaving to introduce observableness to existing code, have a look at the sources for a test coverage tool like Cobertura. That's basically what they do. If you've never done it before, it'll take you a fair bit of head-scratching and sideways thinking to get your head round it all, but stick with it. Be prepared to learn a bit about opcodes as well. Or maybe just plundering the sources for this library is the way to go, not that I'm advocating that ;)
