Converting onClipEvent (enterFrame) to Actionscript 3

I have an old FLA from another designer ca. 2009 or so written with Actionscript 2.0. I've been successful in converting most of it to Actionscript 3.0 to be published in HTML5 except this one function attached to a sprite which changes the transparency of the movie clip based on mouse proximity. I haven't used Flash much in recent years so any help is greatly appreciated!
onClipEvent (enterFrame)
    pointAtWhichAlphaReaches0 = 200;
    hyp = Math.sqrt(_xmouse * _xmouse + _ymouse * _ymouse);
    setProperty("", _alpha, 100 - hyp / pointAtWhichAlphaReaches0 * 100);
    updateAfterEvent(mouseMove);

attached to that object's timeline (which is poor coding):
var pointAtWhichAlphaReaches0:int=200;
var hyp:Number;
this.addEventListener(Event.ENTER_FRAME,f);
function f(e:Event):void{
hyp = Math.sqrt(mouseX * mouseX + mouseY * mouseY);
this.alpha=100 - hyp / pointAtWhichAlphaReaches0 * 100;

AS1/AS2 to AS3 onClipEvent(load),onClipEvent(enterFrame)

onClipEvent (load) {
     total = _root.getBytesTotal();
onClipEvent (enterFrame) {
     loaded = _root.getBytesLoaded();
     percent = int(loaded/total*100);
     text = percent+"%";
     gotoAndStop(percent);
     if (loaded == total) {
          _root.gotoAndPlay(2);
Dear all,
I found a sample code that is writen in AS1/AS2 to see if the load is finished, If finish loading, it will go to the next frame. How do I convent this into AS3? This is my first time looking at AS1/AS2 code, especially onClipEvent (load), _root.getBytesTotal(), onClipEvent (enterFrame), _root.getBytesLoaded(),_root.gotoAndPlay(2).
Can someone help me out with this?
Thanks,
-Zainuu

Hi, Thanks for the reply
stop();
this.addEventListener(Event.ENTER_FRAME, loading);
function loading(e:Event):void{
    var total:Number = this.stage.loaderInfo.bytesTotal;
    var loaded:Number = this.stage.loaderInfo.bytesLoaded;
     trace(total);
     trace(loaded);
    if (total == loaded){
        play();
        mc_Loader.visible=false;
        this.removeEventListener(Event.ENTER_FRAME, loading);
I tried to trace the total bytes and loaded bytes, it returns me
total = 405668
loaded = 405668
Is there a way to show the loaded bytes starting from 1 till 405668? I'm trying to find out if it is really loading the thing. Otherwise is there any other ways to slow down the loading for a bit because it only shows my loading bar for 0.5secs, not really sure if its really loading it...

Converting MXML Components to ActionScript Classes

I'm in the process of converting most (if not all) of my MXML
components to Action Script classes. I've found this is easy, and
doesn't require a lot of extra code when extending a simple
container or control. However, several of my MXML components have
several nested containers and controls - i.e. a component that
contains several Labels, a ComboBox, a TextInput, a Button, and a
DataGrid, plus several other containers needed for layout. To code
the layout of all these containers and controls using MXML, it uses
about 16 lines of code. To code the layout in ActionScript, it
takes about 50+ lines of code (see attached).
I'm just wondering if there are any best practices for
creating ActionScript classes that include several (or even A LOT
OF) containers and controls. It's very easy to layout in MXML, and
is more visibly pleasing to look at and understand, but I feel it
is best practice to code components as ActionScript classes. I know
I should be using MVC, but it's a little late to rewrite the entire
application now.
Any thoughts?

I can't specifically speak to how to write layout code in
ActionScript, but you can look at the generated code that Flex
creates to get an idea of how Flex does it. When you compile an
app, the Flex compiler takes your MXML input and converts it to
ActionScript classes before compiling the entire set of classes
into a SWF. Because of this, you can look at the interim
ActionScript code.
You do this by setting the keep-generated-actionscript
compiler option to true and looking in the /generated directory.

Software for convert Filter Presets to ActionScript Code

This software convert filter presets in Flash 8, CS3 and CS4
to ActionScript code...
Very Fast and Usseful...
http://www.astrodreams.com/flashfilterpresets/convert_flash_filters_presets_to_actionscrip t117release.rar

that's the easy way. just load the bitmap into the library
and reference it. but my client needs the entire app to rely upon
code only, no timeline or library references. so i need to recreate
the line art of the bitmap of a grab icon into graphics api.
wondering if there's an easy convert of a bitmap to graphics api
actionscript code or do i have to just do it by hand which would be
a pain.

OnClipEvent (enterFrame) problem

Hello all! Long time no see. I am having a problem with a
current game that i am developing in flash. The problem is that I
have a movieclip and I want to update the position of one object
everytime, on a loop. The code is in the end of the message. Every
function inside that event is called once, but the horseRun() is
called twice on the same frame and it is updating the object
position twice.
How do I fix it?
See ya!
Augusto

Finding it a bit hard to understand the code ... are you
missing a set of curly braces or an equals sign after the
if(!finish) ? If it's an = sign it should be horseRun without the
brackets:
if(!finish) = horseRun;
And are AI_horseRun() and horseRun() different?

Preloader Problem in Flash MX

Ok, welcome back again...
I must first say... this site is perfect... Solving my
day-2-day Flash mess ups! Ahh, but let us begin!
I've just created a site (more of an Intro to the site),
using Flash and I also created a preloader because of the long wait
before any Flash is actually shown. Unfortunately, I'm getting a
error message when I preview the movie about the preloader... Let
me show you the message:
**Error** Scene=Scene 1, layer=preloader, frame=1:Line 1: Clip
events are permitted only for movie clip instances
onClipEvent (enterFrame) {
Total ActionScript Errors: 1 Reported Errors: 1
I think it may be important to point out that I have about...
Twenty-three layers (That span to about 400+ frames) for that movie
and the preloader layer as the twenty-fourth... Not sure if it's
positioning with the layers affects the script... Ahh! Speaking of
script, let me post the ActionScript that's in the preloader's
first frame:
onClipEvent (enterFrame) {
_root.stop();
mctotal = _root.getBytesTotal();
mcloaded = _root.getBytesLoaded();
percent = Math.round((mcloaded/mctotal)*100);
load = percent+"%";
progress_mc1._xscale = percent;
if (percent == 100) {
_root.play();
I hope that's all the information that is needed for this
question to be answered...
Thanks in Advance!

Well, I am total amateur in actionScript, but if it tells you
"Clip events are permitted only for movie clip instances", it would
mean to me, your preloader is not a movie clip. You need to change
instance propertys for preloader... My head is spinning now, need
to lay down
Good luck!

Kirupa snow tutorial problems

I'm new to Flash, but i really can't get the snow 2.0 (
http://www.kirupa.com/developer/mx2004/snow.htm)
tutorial to work. i've tried the snow 3.0 (
http://www.kirupa.com/developer/flash8/snow.htm)
one without any problems - but I get this error message when I try
the 2.0 one:
**Error** Symbol=snow, layer=Layer 1, frame=1:Line 1: Clip
events are permitted only for movie clip instances
onClipEvent (load) {
**Error** Symbol=snow, layer=Layer 1, frame=1:Line 16: Clip
events are permitted only for movie clip instances
onClipEvent (enterFrame) {
Total ActionScript Errors: 2 Reported Errors: 2
when i test the movie, flash also tells me it's taking too
long and if i continue my computer may become unresponsive?
anyone else have similar problems with this tutorial? (I'm
using flash 8 professional)

do you have a really old mac? i have tried that source file
and on my pc never get tht error - it's
a well known error that signifies a loop script that is too
processor intensive. I am not sure what
to tell you because i can not reproduce this - it may be a
hardware limitation on your mac - try
uploaded your files and proved a url for everyone here to
test.

Converting Actionscript 1.0 to 2.0 in Flash 8

Hi there,
Currently, I am developing game using Flash MX which i using
Action Script 1.0. However, I have install Flash 8.
My question is, how am I to convert the my previous
actionscript 1.0 to actionscript 2.0 in Flash 8?
Thanks.

most of it should be done by flash when you open your a.s.
1.0 scripted swf in flash 8 that has publish settings for a.s. 2.0.
some of it you'll need to do by hand, though.

Questions about this snippet of preloader ActionScript

I'm working on a flash template that uses the following code for its preloader.
onClipEvent (load) {
    total = _root.getBytesTotal();
onClipEvent (enterFrame) {
    loaded = _root.getBytesLoaded();
    percent = int(loaded/total*100);
    text = percent+"%";
    gotoAndStop(percent);
    if (loaded == total) {
        _root.gotoAndPlay(2);
2 things about it that I can't figure out:
The variable 'total' was created inside the first block of code, yet how is it being accessed from the second block of code? Wouldn't there be a variable scope issue there?
Also, in the 2nd block of code, when viewing the actual script in Flash, the variable 'text' is highlighted in blue indicating that it is a keyword or something. And the dynamic text field that's supposed to be connected to the value of the variable 'text' [percent + "%"] is simply named 'z', not 'text'. Yet the whole thing still works fine. Don't understand how.
Thanks,
David

Yeah, weird stuff. Not sure why or how this worked, and I just don't care anymore. Sloppiest code I've ever seen :\. I decided to just publish the file in AS3 and whatever works I'll leave in and what doesn't I'll replace. I guess it's mostly any code that's attached to objects. I also got the following message in the output tab as well which points out exactly what I was talking about with this text field...
WARNING: Text field variable names are not supported in ActionScript 3.0. The variable 'text' used for the text field 'z' will not be exported.
Good riddance to this mess of code.

Action script 3 onClipEvent

i was reading a tutorial for a little game and when ever i
try to run it, i get the error " 1087: Syntax error: extra
characters found after end of program. onClipEvent (enterFrame) { "
the code is:
onClipEvent (enterFrame) {
if (Key.isDown(Key.LEFT)) {
_x--;
if (Key.isDown(Key.RIGHT)) {
_x++;
if (Key.isDown(Key.UP)) {
_y--;
if (Key.isDown(Key.DOWN)) {
_y++;
it seems to work for everyone else. Your help is greatly
appreciated.

if you're using as 3, there's is no onClipEvent() and there
is no code that can be attached to an object. read the help files,
programming with actionscript 3.

Actionscript Slideshow horror!!!

Hey everyone,
I've got a simple random actionscript slideshow that loads
external jpgs into a mc. Everything works good but i can't get the
darn jpgs to fade in and out. Could someone please help, the
deadline approaches.
Here is the AS for the movieclip, it's in the 1st frame:
mc = function() {
num = (Math.round(Math.random()*2));
// 50 being the number of your jpg, rename them from 0.jpg to
49.jpg
totalfilename = num + ".jpg";
picLoader.loadMovie("
http://www.venture-multimedia.com/factory/flash/"
+ totalfilename);
// _root.picLoader being an empty movie clip instance name
picLoader, just rename it to watever is
//your movieClip name and rename the address of your site and
folder where your images are
mc();
// If you want them to come on an interval of 20 seconds
clearInterval(mc.intID);
mc.intID = setInterval(mc, 3000);
An here is the AS for making it fade in and out. This is applied
to the mc itself:
onClipEvent (load)
this._alpha = 0;
onClipEvent (enterFrame)
if (this._alpha < 100)
this._alpha = this._alpha + 5;
} // end if
if (this._alpha >= 100)
this._alpha = 100;
} // end if
Thanks for your help!

So the end of this message got cut off
I'm wondering how to get the images to fade on ans opposed to
just showing up?
Thanks:
Graphic Graeme

Actionscript 1 to 2 button reverse

Hey guys, i found some nice code on AS1 to use with my Button and MC.
Basically
the MC doesnt play when mouse is not on button
when mouse over button i want the MC to play. (only once then stop)
when mouse off button i want the MC to play in reverse. (and stop when its back to the beginning)
(btw both the MC and Button are in a movie clip - as i need to make many of them)
the code is in AS1 and doesnt seem to work in AS2 which is where i need it.
Maybe someone can see whats wrong and convert parts for me or give me a new code
code for button:
on (rollOver) {
mc1.goBack = false;
mc1.play();
on (rollOut) {
mc1.goBack = true;
code for MC:
onClipEvent (enterFrame) {
this.rewind();
code for actions layer:
MovieClip.prototype.rewind = function () {
if (goBack && (_currentframe>1)) {
gotoAndStop (_currentframe-1);
thanks i really need this code!!!! appriecate any1s help =)

remove code from your button and assign your button an instance name, say btn:
btn.onRollOver=function(){
mc1.onEnterFrame=function(){
this.nextFrame();
if(this._currentframe==this._totalframes){
delete this.onEnterFrame;
btn.onRollOut=function(){
mc1.onEnterFrame=function(){
this.prevFrame();
if(this._currentframe==1){
delete this.onEnterFrame;

Snow falling: pls help with actionscript

Hallo,
I made a flash movie with snow falling from the sky in Flash 8 (actionscript 2.0)
However, the snow I made differs from the original.
The original is here:
http://www.kirupa.com/developer/mx/snow.htm
I put mine here:
http://toetssite.webs.com/
You will notice that my snow only falls downward: there is no randomness for the flakes to go left or right. there is no movement.
WHere in the script below can I change that so that there's more movement for the flakes? Thank you
I use the following script for the snow itself:
onClipEvent (load) {
     //specifies the size of the movie stage
     movieWidth = 300;
     movieHeight = 200;
     //variables that will modify the falling snow
     i = 1+Math.random()*2;
     k = -Math.PI+Math.random()*Math.PI;
     //giving each snowflake unique characteristics
     this._xscale = this._yscale=50+Math.random()*100;
     this._alpha = 75+Math.random()*100;
     this._x = -10+Math.random()*movieWidth;
     this._y = -10+Math.random()*movieHeight;
onClipEvent (enterFrame) {
     //putting it all together
     rad += (k/180)*Math.PI;
     this._x -= Math.cos(rad);
     this._y += i;
     if (this._y>=movieHeight) {
         this._y = -5;
     if ((this._x>=movieWidth) || (this._x<=0)) {
         this._x = -10+Math.random()*movieWidth;
         this._y = -5;
and on the first frame of my movie I put the following:
for (k=0; k<50; k++) {
    duplicateMovieClip(this.snow, "snow"+k, k);
Thank you!

Just initialize the rad variable. I added following line to your code and it works fine.
     rad = 0; //line I inserted.
No other change required. It is advised to initialize all your variables before you use them.
Anyways, below I am providing the whole script for the snow after modification
onClipEvent (load) {
//specifies the size of the movie stage
movieWidth = 300;
movieHeight = 200;
rad = 0; //line I inserted.
//variables that will modify the falling snow
i = 1+Math.random()*2;
k = -Math.PI+Math.random()*Math.PI;
//giving each snowflake unique characteristics
this._xscale = this._yscale=50+Math.random()*100;
this._alpha = 75+Math.random()*100;
this._x = -10+Math.random()*movieWidth;
this._y = -10+Math.random()*movieHeight;
onClipEvent (enterFrame) {
//putting it all together
rad += (k/180)*Math.PI;
this._x -= Math.cos(rad);
this._y += i;
if (this._y>=movieHeight) {
this._y = -5;
if ((this._x>=movieWidth) || (this._x<=0)) {
this._x = -10+Math.random()*movieWidth;
this._y = -5;

Converting AS2 to AS3 Please!

Hi guys.
I having a major problem in trying to convert an old AS2 code into AS3.
It would be great if you guys could help in anyway you can.
onClipEvent (enterFrame)
    this;
    if (_x > 520)
        setProperty(this, _x, -20);
    } // end if
    this;
    if (_x < -20)
        setProperty(this, _x, 520);
    } // end if
    setProperty(this, _x, _x + Number(1.250000E+000));

In the timeline of the object in question, try:
addEventListener(Event.ENTER_FRAME, moveX);
function moveX(evt:Event):void {
    if(x > 520){
         x = -20;
    if(x < -20){
         x = 520;
    x += 1.25;

Help converting AS2 rollover buttons to AS3

This is probably a really dumb question, but I'm very new to AS3 so please bear with me. I created some rollover buttons (movieclips) for a flash website in AS2 using the following code:
onClipEvent (enterFrame) {
    this.onRollOver = function() {
    this.gotoAndPlay(1);
onClipEvent (enterFrame) {
    this.onRollOut = function() {
    this.gotoAndStop(1);
on (release){
    getURL("index.html", "_parent");
Could anyone advise me on how to start converting this code into AS3? I know I have to use an EventListener but I don't really understand how it works.
Any assistance would be greatly appreciated!

I have changed my code to:
Link1.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
Link1.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
Link1.addEventListener(MouseEvent.CLICK, onClick);
function onMouseOver(e:MouseEvent):void {
        Link1.gotoAndPlay(1);
function onMouseOut(e:MouseEvent):void {
          Link1.gotoAndStop(1);
function onClick(e:MouseEvent):void {
        Link1.navigateToURL(new URLRequest("index.html"), "_parent");
But it still doesn't work very well. The animation for the rollover keeps playing over and over, ignoring the "stop" I have within the frame of the movieclip.
You can view my website at: http://www.halopantryandgrill.com/test/index.php to get an idea of how my rollovers worked before. This was done in AS2.
I can't seem to get the same effect to work in AS3
