Re: [Flashcoders] How to expand import * statements?

FlashDevelop does that for you in AS2 (and I think AS3, I just haven't
gotten to play with that yet).  I've pretty much stopped writing
imports manually. :)

Re: [Flashcoders] clean scripting

[Andy Herrman]

Here's my understanding of the reason behind this:

AS2 is basically just syntactic sugar over AS1, and gets compiled down
to the same thing.

When defining a class you're actually defining things on the
prototype, so doing this:
--
class MyClass {
  public var myArray:Array;

  public function MyClass() {
myArray = [];
  }

  public function push(o:Object):Void {
myArray.push(o);
  }
}
--

would be the same as:

--
MyClass = function() {
  this.myArray = [];
}

MyClass.prototype.push = function(o) {
  this.myArray.push(o);
}
--

If you set the value of the member variable at declaration:
--
  public var myArray:Array = new Array();
--

It turns into this:
--
MyClass.prototype.myArray = new Array();
--

Since you have just assigned an array instance to the prototype of the
class, that gets shared between all instances of the class (basically,
the value you set there is the initial value given to the myArray
member of the class on instantiation).

Well, assuming my understanding is correct. :)

Re: [Flashcoders] Flash is full of surprises. I will show you how to move movie-clip using a reference to another deleted clip.

[Andy Herrman]

So, the case he brought up was different from what you said.

In your case you're creating differently named movie clips, and
explicitly assigning them to the mc variable.

In the original code, a new movie clip was attached with the same
name, but NOT assigned to the variable.  After doing so you would
expect the variable to not work, but it ended up pointing to the new
clip.

  How else would you expect to be able to attach movieclips and manipulate

  e.g.

  function doClips() {
 var mc:MovieClip;

 for(var i = 0;i  10;i++) {
mc = attachMovie(star, star_mc_ + i, getNextHighestDepth());
//mc.removeClip();
mx._x = 100 * i;
 }

 //would expect to manipulate the last one.
 mc._y = 100;
  }

  doClips();
  //compile error, but would not work anyway.
  mc._y = 200;
  //would work.
  star_mc_9._y = 200;

  I bet the reference goes out of scope once you exit the function you are in?

  If not, then that maybe a bug.

Re: [Flashcoders] How to call class method from a movieclip?

[Andy Herrman]

If you want your contentMC class to be able to call methods on your
myClass then you should probably pass the myClass instance to the
contentMC.  Basically, add a parameter to contentMC's constructor of
type myClass, and pass a reference to 'this' when you create it.
Something like this:

public class myClass extends Sprite{

  public function myClass() {
var contentMCs:MovieClip; = new contentMC(this);
  }

  public function myMethod(){
  }
}

On an unrelated note: standard practice has class names start with a
capital letter, not lowercase like you have.  It helps to
differentiate between variable names and class names.

Re: [Flashcoders] buttons lined up next to each other- rollout not work

[Andy Herrman]

Try using a variable local to the for loop for the target:

//this also sets the event handling in one shot
for (i=0; i5; i++) {
   clipName = this[clip+i];
   var myTarget= _root[text+i]
   trace(target);


   clipName.onRollOver = function() {
   Tweener.addTween(this.person,{_alpha:100, delay:0, time:2});
   Tweener.addTween(this.whiteborder,{_alpha:100, delay:0, time:2});
   Tweener.addTween(myTarget,{_alpha:100, delay:0, time:2});
   trace(onrollover+myTarget);
   };

   clipName.onRollOut = function() {
   Tweener.addTween(this.person,{_alpha:30, delay:0, time:1});
   Tweener.addTween(this.whiteborder,{_alpha:0, delay:0, time:1});
   Tweener.addTween(myTarget,{_alpha:0, delay:0, time:2});
   };

}

My guess is target is declared outside the for loop, so you're having
some problems with closure.  I don't know if AS's closure works the
same way as C#'s, but if it does then this could be the problem.

This article is specific to C#, but it does a good job of going over
how closures and anonymous methods work, and might be helpful to
understand this (assuming I'm right in that AS's behavior matches C#'s
for closure)

for an example of the possible differences between what you have and
what I suggested.

Re: [Flashcoders] Classes added

[Andy Herrman]

 So then it is safe to do

 import flash.display.*;

Only if you're not going to run into any naming conflicts.

I generally find it's better to only import the classes you're going
to use, for a couple reasons.

1) It reduces the chance of naming conflicts (like two packages having
Button classes in them).  The only time you'll have to deal with
naming conflicts here is if you actually need to use classes with the
same name from two different packages.  If you import the entire
packages there's a higher chance of conflict.

2) It makes it much easier to tell, at a glance, what a class depends
on.  This can be beneficial in many cases.

Re: [Flashcoders] extends implements

I normally just declare the extends, as the docs for the base class
would already show that it fits the interface.  However, in my AS2
code (I'm also working in java, C#, and C++ right now) I've started
declaring the interfaces as well.  The reason I started doing that is
that the documentation generator I'm using (as2api) doesn't seem to
properly inherit the documentation from the interface unless I
explicitly declare it.

 Hi folks,

 I was wondering about your personal/professional preference regarding the

 Say you have an interface IEvent and a base class Event which implements
 IEvent.

 Now you are creating an event subclass MyEvent which can:
 - implement IEvent
 - extend Event
 - both

 In other words, would you when choosing to extend Event still declare it as
 an implementation of IEvent for the sake of readability:
 class MyEvent extends Event implements IEvent OR
 simply class MyEvent extends Event

 I see pro's and con's to the both of them, but I guess I'm looking to see if
 there is some sort of 'why declaring blablahb is evil'.

 I guess I'm used to adding the implements clause as well, since it allows me
 to change the superclass and testing whether I still adhere to the required
 interface by compiling that class instead of compiling any source that uses
 it. In addition I hope it prevents people from declaring variables like var
 a:Event instead var a:IEvent...

 tnx in advance.

Re: [Flashcoders] Reliable way to split a string into an array of lines?

[Andy Herrman]

The fastest (execution, not writing) way would probably be to do your
own loop over the string and find all the positions of line breaks
(either \r or \n) and use just use substring to pull out the
individual lines.

If you do end up trying RegExes I'd be very interested in how you do
it.  The only regex library I've found for AS2 doesn't compile with
MTASC (looking at the code I don't know why anything would compile
it), which is causing me significant annoyance.  If you find one that
works with MTASC I'd love to know about it. :)

Re: [Flashcoders] toString(aArray[i]) ?? does this work

[Andy Herrman]

Ah, since the local scope is the object in the array then just using
`toString()` without any arguments would work (just doing
`this.toString()` basically).

Can you provide the code where you populate the array?  It's possible
you're adding something other than the movie clips to the array (or
maybe some type info is being lost).

I'm actually not sure how the `i` variable is handled in this case.
If you're always getting 126 then Flash might be keeping a reference
to the variable and evaluating it when the function runs, instead of
evaluating it when creating the function.  This might be how things
work, I really don't know.  A different way to handle it would be to
do this:

aArray[i].myArrayIndex = i;
aArray[i].onPress = function() { ... }

and then within the function use `this.myArrayIndex` instead of `i`.
This way you're storing the index for the object within the object
itself, so you can query it whenever you want without worrying about
the scope chain.

One other thing, just as a sanity check.  You said you did this:

setInterval(rollOvers,10);  //calls function 100/second to

If that's the actual code then you're going to have problems.  That
will run your rollOvers function every 10 milliseconds.  You probably
only want it run once (no point in changing the onPress functions when
they've already been assigned).  You're going to want to store the
interval's ID and then clear it:

var rollOversInterval:Number = setINterval(rollOvers, 10);

function rollOvers() {
  clearInterval(rollOversInterval);
  /* rest of the function */
}

If for some reason you do need to update the onPress functions you
should really only do it when an event occurs that would require it,
instead of constantly doing so.

 Andy,
   I see what you are saying, I think.  That the .toString() has to be used

 myMCinArray1 or  myMCinArray2 or myMCinArray3 etc  when I use the
 toString on an array Element.

 By the way, the scope in this case is actually  the Array
 lement(MovieClip)  -see coded snippet

 setInterval(rollOvers,10);  //calls function 100/second to

 function rollOvers(){
 for (i=0; iaArray.length; i++) {

 aArray[i].onPress = function() {
var myStr:String = aArray[i].toString();   //* THIS LINE

trace(i);  //gives me 126 .which is the array length. if I

 fine too.
 };

  I think what you really want is this:
 
  var myStr:String = aArray[i].toString();
 
  I don't know of any global toString() function.  What's probably
  happening is that you're doing the equivalent of
  `this.toString(aArray[i])`.  The scope object's toString function
  ignores all arguments and gives you the string representation of
  itself (which will be what you said you're seeing unless it has a
  custom toString() implementation).

Re: [Flashcoders] toString(aArray[i]) ?? does this work

[Andy Herrman]

You say [object Object] is the correct output if the object is a
movie clip.  This isn't the behavior I see.  Any time I trace a movie
clip I get the clip's name (level0.foo.bar.whatever), not the generic
object results.

Re: [Flashcoders] How to share class library across a network?

[Andy Herrman]

Try mapping the network share to a drive letter (I'm assuming you're
in Windows here).  Some tools don't work well with network paths, but
if you map the shared folder to a drive letter then it would appear to
those tools as a local path.  That might help fix your compile errors.

 Hi there, I would like to share my class library with other

 Almost every time we exchange a file lots of compiler errors are
 thrown up even though the class paths are set correctly, this is
 usually rectified after restarting the computer or Flash.

 I have copied my class library to a network share but when I compile
 a SWF from Flash I get lots of compiler errors starting with line 6
 of toplevel.as

 'The class or interface 'Boolean' could not be loaded'
 'The class or interface 'Object' could not be loaded'
 'The class or interface 'Number' could not be loaded'

 If I point my class path (set in my AS preferences for the Flash app)
 to an exact copy of the same folder but on my local drive everything
 works fine!

 If someone could help me out here I would be really grateful, this is
 proving a real headache!

Re: [Flashcoders] Displaying Progress of calls to external scripts

Re: [Flashcoders] Traversing through Object goes backwards

[Andy Herrman]

Objects work pretty much like hashtables (from my understanding).
Hashtables generally don't guarantee any kind of ordering.  Flash may
enforce some kind of ordering (y seems to be going in reverse order of
when things were added) but I don't know of any ordering and generally
treat it as arbitrary.

Now, if you were using Arrays then your ordering would be guaranteed
(for-in loops go backwards through the array I believe).

Re: [Flashcoders] Function call from a function

[Andy Herrman]

You're having scope issues.  When the onRelease function is called its
scope is the movie clip (closer_mc), not the class.  Try this:

At the top of your class' file:
  import mx.utils.Delegate;

Then define the onRelease function this way:
  target_mc.closer_mc.onRelease = Delegate.create(this, removeMC);

The Delegate will cause the removeMC function to be called with the
class as scope (or whatever object you put as the first argument to
create).

 Of which contains a removeMovieClip();


 Except it doesn't does anybody have any advice on calling functions from

Re: [Flashcoders] Can't access

[Andy Herrman]

My guess is that your this variable is getting mixed up.  I'm not
familiar with the Delegate.function usage, but that function may be
being called with a scope you're not expecting.

Try just using a regular function there.  You've already set up the
'ref' member of the 'swfListen' object, so 'this.ref' should give you
what you want.

[Flashcoders] Strange FMS application initialization problem

[Andy Herrman]

Our production servers have run into a strange problem initializing
application instances and I'm wondering if anyone else has seen it (I
couldn't find any mention of it online, but my google skills aren't
the best).

Sometimes when an application is initializing and loading its
dependent files we get the following error in the logs:

Sending error message: Unknown exception.   -

At this point all the loading stops and the application starts.  Since
the required files weren't loaded the application breaks in various
ways (lots of reference errors for things not being defined).

Sometimes we've seen this happen before any of our files have been
loaded, sometimes after one or two of them are loaded (our application
has a large number of files).  I can't find anything online, and
haven't had any luck reproducing it consistently.

Has anyone seen this before?  Any idea what could be causing it?

Re: [Flashcoders] Iterator question

[Andy Herrman]

Why not use a hashtable instead of an array?  Give your elements all
unique IDs (you could even just do an incrementing integer).  A
hashtable would give you faster lookup (don't have to iterate over the
array searching for it) and you can remove hashtable entries without
messing up any kind of ordering.

  Hello list,
 
  i have a page object that contains has a Array that holds
  pageElements. This is a storage for elements with an iPageElement

  The page object has an destroy() method. When page.destroy() is
  called, it will loop trough the page.pageElements Array using an
  iterator. Every iPageElement broadcasts an onElementKilled message
  when is has been destroyed. When a pageElement broadcast this message,
  the page need to continue in deleting the next element in the
  page.pageElement Array.
  The callback method onElementKilled in the page instance, searches for
  the element that has been deleted and then removes it from the
  page.pageElements Array. This is where i think a problem rises,
  because if the page.pageElements array is updated during the process,
  the index does not match the element to remove anymore. How can I
  solve this potential risk?
 
  Another question, the array that is passes into the iterator is a
  reference to the pageElements Array. Does this mean, that if I delete
  an element from this array from within the iterator, the
  page.pageElements array is modified?
 
  I hope my question is clear..

Re: [Flashcoders] Real Player 11 messing up Flash application UI

[Andy Herrman]

Just ran into another issue, and this one is actively breaking things,
not just causing UI annoyances.

RP11 seems to be doing something to prevent LocalConnections from
being cleaned up.  Our application uses a couple SWFs for the UI,
using LocalConnections to communicate between them.  One of these SWFs
gets reloaded sometimes (the frame it's in can be navigated away from
at times).

Normally everything works fine because the unloading of the SWF when
the page changes cleans up the LocalConnections.  However, with RP11
installed the cleanup doesn't seem to happen.  The first time the SWF
loads it works fine, but every time after that it fails to open the
LocalConnection, completely breaking the application.

I submitted this issue using their feedback form, but I don't know if
anything will come of it.

Re: [Flashcoders] Intro to OOP using ActionScript: patterns derail!

[Andy Herrman]

The fancy names are kind of useful actually.  Most of the patterns
I've learned but I didn't know the fancy/official names for them.
This caused some confusion when talking with my coworker as he would
be simply using the names instead of the concepts and I'd have to stop
and figure out which one he meant, or I'd spend extra time explaining
what I was talking about when I could have just said the name and been
done with it.

The names are useful as a common/shared way of referencing complex
concepts.  That said, the concepts are much more important than the
names, as you can get by just fine with only the concepts, but fail
miserably on with just the names. :)

  Right. Delegate - ie Proxy. I agree. I wasn't saying patterns

  these days without teaching Observer, but you might not ever call it
  that. In fact, I wonder who does call it that in a class? Actually,
  the more I think about it, I think for students it might be best not
  to call these patterns and just teach them. Then, once they know how

  encapsulation I think - if you just show your students how to write

  likely just use them.
 
 
 That is what I have been saying from the start of this discussion.  You
 do not have to teach the fancy names. Just teach them to use proper
 coding practices. OOP and Design Patterns are just names that we use to
 group a bunch of best practices into theories so we can discuss the
 theory and have a framework to critique code. I have a feeling that for
 most of us, the word polymorphism is not much of a help and I see no
 reason to even use the word on 14 year olds until the last week of class
 and only then as a warning that someday someone might try to use it on
 them in a discussion about design.

[Flashcoders] Real Player 11 messing up Flash application UI

[Andy Herrman]

For those who don't know, Real Player 11 (in beta right now) added a
feature that lets users download videos embedded in flash applications
(like youtube, google video, etc).  It does this by adding an entry to
Flash's rightclick menu and by having a mini-toolbar appear at the top
left of the flash movie when it loads and when the mouse goes over the
movie.

Does anyone know what method it uses to determine if a SWF is used to
play a video?  It seems to think that our Flash application serves
video even though it doesn't, and the toolbar thingy they're adding is
showing up over par of the UI and could confuse users.  I haven't been
able to find any documentation about how they're detecting it.  Anyone
played around with this yet?  Are there any known methods to prevent
that toolbar from appearing?

Re: [Flashcoders] Classes 101 [was: Version control and Flash ]

[Andy Herrman]

The reason I don't like extending MovieClip is that it gives the user
of my classes too much control over the internals of my class.

Specifically, if I'm wrapping MovieClip I'm generally creating
something with a lot of special behavior, which sometimes causes
restrictions on things like position and size.  If I extend MovieClip
then all the built in MovieClip functions and properties are
user-visible, so there's really nothing stopping someone from just
doing myClass._width, etc.

By using Composition I can restrict the public API to my class to
exactly those methods I want exposed.  All the extra internal state
that MovieClip makes visible is no longer visible to the user of my
class.

Now granted, if I'm the only one using my classes then you could argue
that there's really no difference, as I should just stick to using the
functions.  However, I like to code defensively and assume that, at
some point, others will be using/modifying my code.  Using Composition
makes it much easier to do that.

 class) or is this a higher level theoretical argument?

Re: [Flashcoders] fms application class

[Andy Herrman]

The only way for a client to call a method is for that method to exist
on the Client's object.  That's just the way the Flash RPC stuff
works.  You can either add it to the Client prototype (which I don't
like) or add it to the client object after they connect (my preferred
way).

For instance:

application.onConnect = function(oClient, oParams) {
  this.acceptConnection(oClient);
  oClient.helloServer = function() {
trace(Hello Server);
  };
}

Or, you can get fancy and do some delegate-style work so that your
actual function is defined on application (or some other object):

application.helloServer = function() {
  trace(Hello Server);
}

application.onConnect = function(oClient, oParams) {
  this.acceptConnection(oClient);
  oClient.oScope = this;
  oClient.helloServer = function() {
this.oScope.helloServer.apply(this.oScope, arguments); };
}

The reason you're getting an error about the function not existing is
that it doesn't.  When the client makes a call the server looks for a
function of the given name on the client's object.  If it doesn't
exist you get an error.

I hope that helps!

Re: [Flashcoders] garbage collection and asychronous execution

Which is probably a good argument for always using the other form of

setInterval's internals now has a reference to it.

 No, it's a reference to a function. The VM doesn't know anything about

 The interval keeps a reference to the function, the object gets
 garbage collected, then the function gets called. It doesn't need an
 object. In fact, if you'd add a trace( this ), it would be undefined.

Re: [Flashcoders] Prevent flash from caching the loaded assets

[Andy Herrman]

Yes, the SWF would be easy to decompile, but I think as soon as you
start worrying about someone decompiling the SWF to cheat you're
pretty much out of luck, as they can always decompile your game's SWF
instead and find out everything there is to know about the game.  That
would probably give them a lot more options for cheating. :)

If you want to go the AMFPHP route (which I'm not familiar with at
all) and sending a large array is having problems, why not split it
up?  Send a couple smaller arrays and then combine them on the client
side.

On 8/6/07, Niels Endlich [EMAIL PROTECTED] wrote:

 We were working on sending an array with amfphp which contains the pixel

 But it seems that AMFPHP isn't able to send such a large array (800x600pix).

 Has anyone done somthing like this before?

Re: [Flashcoders] stage.stageWidth annoyance

[Andy Herrman]

I can't speak to AS3, but in AS2 I have to do an interval which
constantly checks the stage width.  Initially it's the size given at
build time, then it switches to 0, then some time later it switches to
the actual size.  I have all my initialization wait until I see the
size set to something other than 0 or 1 (I set everything to 1x1 at
build time so I can detect it).

I'd hope it's better in AS3, but maybe not.

Re: [Flashcoders] Prevent flash from caching the loaded assets

[Andy Herrman]

I think the caching is controlled by the browser, not Flash itself, so
I don't believe there's a way within flash to prevent caching.

Maybe you could do some trickery with the images that makes it harder
for the person looking at the cached stuff to see it.  Like, split up
the main image into multiple ones and maybe apply some transformations
to the images, and then have the flash movie undo the transformations
and compose the images back into the main one?

Re: [Flashcoders] Backend compiled Java or scripted PHP?

[Andy Herrman]

I haven't done any work in PHP so I can't really comment on its
usefulness, but I've found doing web stuff in Java isn't particularly
hard.  There are a number of possibilities for doing Java work on the
server that makes it easier too.

We use Apache Tomcat here.  It handles all the HTTP handling and such
and makes things pretty easy, and we do some very complex processing.
However, as others have mentioned, if you're just doing simple
processing tasks then it's most likely overkill.

As far as building up a skillet, I think Java is more generally useful
(you'll be doing server work but the skills you learn can be applied
to client code as well, and even embedded stuff to some extent, though
I haven't done any of that).  PHP, on the other hand, tends to be more
limited in where it's used (from my understanding).

own server in PHP either. PHP is really just about
doing things with HTML. The filesystem, image
manipulation, and other functions are secondary to
that.

Java is meant for applications, which means that you
can make it mangle HTML, but it takes longer.

You could never write a server in PHP, but if you
wanted to throw a simple XML file at a Flash

pretty sure those are blocking actions, so once it's returned the clip
exists.

 I'm writing a component and have created a MovieClip with

 first MC with createEmptyMovieClip, it is undefined. This must be a
 basic Flash thing. I haven't used createEmptyMovieClip too much.

 I tried
 private var ItemContainer:MovieClip;
 private var CContainer:MovieClip;

 this.createEmptyMovieClip(ItemContainer, this.getNextHighestDepth());
 this.ItemContainer.createEmptyMovieClip(CContainer,
 this.getNextHighestDepth());

 When I trace ItemContainer, it comes up as
 _level0.testDualListJumble.ItemContainer.  I tried chaning the parent mc
 to _level0.testDualListJumble.ItemContainer  -
 _level0.testDualListJumble.ItemContainer.createEmptyMovieClip(CContainer,

Re: [Flashcoders] Question on old AS1 code

[Andy Herrman]

The HTTP vs HTTPS stuff should be completely handled by the browser,
so I don't think the plugin would have any issues.

One thing I find helpful for debugging these kinds of problems is
Fiddler (http://www.fiddlertool.com/fiddler/).  This will log all
requests IE makes and the responses to them.  Try installing it,
starting it up (it adds a button to the IE toolbar), and then loading
your SWF.  You'll be able to see what files are being requested.  You
can see if you're getting 404 errors, or even if they're being
requested properly.  This might help track down the problem.

Hello all. This is my first post on the group, but I'm a regular member
of the FlashNewbies list. I'm a fairly new Flash developer using Flash
8, web player 9, and IE6. Hopefully the members of this list can offer
some guidance with a problem.

Background:
I've been asked to review some old Flash 5 or 6 code from another
developer built in 2001 or early 2002. The code is completely
undocumented and the original developer is unavailable. The FLA and AS
files load a few external JSP files and produce a detailed graph from
those files. On an HTTP server the files work as expected and have been
working properly for several years.

Problem:
Recently the web team moved the files to an HTTPS server. The background
graphics load normally but the external data is completely blank. I have
access to the FLA and AS files and have reviewed the code. Being a new
developer I can't detect any obvious problems with the FLA or AS files.

The external data files are referenced by name only, not by an explicit
file path. I have been assured by the web team that the necessary files
are all present and located within the same folder.

Question:
Are there any known compatibility or security problems between Flash
player 9, AS1 code and using HTTPS servers? Any ideas what might be
causing this problem?

I do not have direct access to the servers so I cannot give specifics
about how the servers are configured, but I can forward questions to the
web team. Also, the code is proprietary so unfortunately I'm not able to
post or share the actual code.

Any suggestions are welcomed and appreciated.

Regards,

Dave

Re: [Flashcoders] Combo Box Component Errors

[Andy Herrman]

I responded to your direct e-mail with a more detailed explanation,
but for the benefit of the list:

The way to fix this is to either do:

this._lockroot = true;

at the top of the AS code in the SWF that contains the combo boxes, or do:

loadedMovie._lockroot = true;

in the loader movie, where loadedMovie is the movie clip that the
movie was loaded into.

Hi there,

I am having a unique problem using the combo box component. When I run

Would you mind taking a look and seeing if you can see my error?  **
Sorry for the double post newbies.**

In the test file, I drug 4 combo box components to the stage and gave
them the
instance of combo1, combo2, combo3 and combo4.

Here is the code in the test file:

function change(evt) {
trace(evt.target.selectedItem.label);
trace(evt.target);
for (var i = 1; i=numComboBoxes; i++) {
thisComboBox = this[combo+i];

numComboBoxes = 4;
for (var i = 1; i=numComboBoxes; i++) {
var thisComboBox = this[combo+i];

thisComboBox.addItem({data:dataNum++, label:});

thisComboBox.addEventListener(change, this);
thisComboBox.selectedIndex = 0;

Then in a second file I created a loader.  Here is the code:

function loadComplete():Void
{
trace(the clip is now loaded and on timeline

I am having the same issue. It works by itself, but not in the loader.

Any ideas?  I am stumped!

Re: [Flashcoders] Whats the best way to communicate with the serverside?

[Andy Herrman]

It really depends on what kind of data you need to pass around.

One other option is to have the server be able to receive XML data and
respond with other XML data.  Flash can generate and parse XML fairly
easily.  We do something similar to this in our application, where Flash
generates an XML document, sends it to the server and then parses the
received XML.

Take a look at the XML class's sendAndLoad function.

We use a lot of javascript and dwr(Ajax) to do a lot of our web side

Re: [Flashcoders] Strange ComboBox issues when loaded in a child SWF

[Andy Herrman]

I have 2 movies.  The main movie has all of the code, and the UI
resources movie contains all of the assets, with no code and nothing
on the stage.  When the main movie loads it displays a loading
progress bar, creates an empty movie clip and then loads the UI
resources SWF into that empty clip.  Once the UI resources are
downloaded the UI is constructed by the code in the main movie, but
doing everything within the clip that contains the UI resources
(basically, treating the UI resources clip as the root, so all
attachMovie and createEmpty... calls are done on the UI Resources
clip, or one of its child clips).

One of the reasons we do it this way is that we want to have a little
as possible stored in the FLA, as it's a binary file and is a pain to
use with source control.  The UI resources movie is actually defined
in an XML file and we use swfmill to generate the SWF.  The XML file
is much easier to use with source control as it's plain text (tracking
changes is much easier).  So the main movie's FLA is almost completely
empty.

 running into some weird issues with ComboBox when doing this.

 I've found workarounds for all these issues, which I thought others
 may find useful.  I'm also interested to know if other people have run
 into them and how they solved them.

 The first bug I ran into was that the combo box would never open.
 Originally I set _lockroot to true on the movie clip that contained
 the combo box.  However, in this case the dropdown would always open
 down, even if there wasn't enough room in the movie to do so (which
 normally would cause it to open up).  I found that doing _lockroot on
 the UI resources movie fixed this.

 The second bug I ran into was that a focus rectangle would display
 around the combo box and the dropdown.  This doesn't display when the
 combo box is simply created in the main movie (which I can't do
 unfortunately).  Also, the focus rectangle for the dropdown does not
 go away when the dropdown is closed, messing up the UI.  The fix I
 found for this was to do the following, where cbx is the ComboBox:

cbx.drawFocus = null;
cbx.dropdown.drawFocus = null;

 The last issue was a fun one.  If there were enough entries in the
 combo box to require scrolling, clicking on the arrows in the
 scrollbar or dragging the scroll thingy would cause the dropdown to
 close (it closed on the release of the mouse).  This only seems to
 happen when the combo box is in a child movie.

 By digging through the ComboBox code and doing a bunch of tests I
 determined that the combo box's onKillFocus() function was being
 called after the mouse was released (this never happened when in the
 main movie, only when in the child movie).  onKillFocus takes a single
 argument, which I think is a reference to the object that was taking
 focus.  In this case the argument was always the dropdown itself
 (stored in the combo box as __dropdown).

 The fix for this is a total hack, but seems to work in Flash 7+ (at
 least in windows).  At the very beginning of the code for the movie I
 put the following:

ComboBox.prototype.onKillFocus = function(n) {
  if(n == this.__dropdown) {
/* Skip */
  } else {
if(this._showingDropdown  n != null) {
  this.displayDropdown(false);
}
super.onKillFocus();
  }
}

 This overrides the ComboBox function to do what it normally does in
 all cases except for when the focus is being given to the dropdown.
 The only thing I've found that this breaks is changing focus using the
 TAB key.  If the combo box is open and you hit the TAB key to change
 focus to something else then it won't close.  This was easily fixed by
 adding a key listener that closes the combo box when it sees TAB is
 pressed.

 We're 6 weeks into our last AS2 project, with about a week left for
development.  Now we hit what seems like a brick wall.

 We select an item from the dropdown and it works fine the first
time.  The second time it works okay.  The third time it just stops
 working.

 There is apparently a reference in the component to the root timeline
that prevents it from operating normally.  We've tried
 _lockroot, we've tried swapping depths of __dropdown every single time
you click on the combo box.  None of our hacks work.

 We tried the bjc bitcomponent combobox and it looks horrendous and
doesn't seem to fire any of the events, either.

 Any suggestions?

Re: [Flashcoders] functions for other classes within a class

[Andy Herrman]

Since that function is a class function the compiler assumes it will
only be called with that class as the context.  Since Controller
doesn't have the function then it won't compile.

What I would do is this:

import mx.utils.Delegate;
class com.tequila.canon.PosterArtist.Controller {

  private var portfolio:MovieClip;

  public function Controller()
  {
  trace(Controller constructor:  + this.portfolio);

  this.portfolio.addEventListener(onClick,this);

  this.portfolio.onInit = Delegate.create(this, this.portfolioOnInit);
  }

  private function portfolioOnInit():Void
  {
  trace(onInit:  + this);
  this.portfolio.flipCorner(bottom_right);
  }

}

That way your class function is always called with the right context
(this value).

I second that suggestion.  Gmail is really good for storing mailing

gentoo related ones (massively high traffic).  Between the two lists I
have over 19000 conversations (which can each have a large number of
individual mails).  Mail.app on the mac and thunderbird had problems
dealing with that much stuff if I wanted to search through them, but
gmail's search is pretty much instantaneous.  I've found it's much

Re: [Flashcoders] splitting the list?

Yea, but the ads are unobtrusive and 90% of the time I don't even
notice them.  The other 10% are when I look at them just to see what
kind of random things are being displayed (I've seen some very strange
ads come up and I try to figure out what could have triggered them.
It's fun).

Forums aren't nearly as convenient.  As Ian mentioned, you have to
choose to go to them on your own to see what's available.  Mailing
lists let you keep a central place to go for everything (your mail
client of choice).  I find mailing lists much more flexible and
responsive, as I have full control over how I look at it and I don't
have to go out of my way to see if anything has been added to the
list.

Also, mailing lists feel more like a 'standard' than forums, as they
all use the same 'interface', instead of the widely varying software
and interfaces for forums.

 I second that suggestion.  Gmail is really good for storing mailing
 lists.  My account has this one (fairly high traffic) and a couple
 gentoo related ones (massively high traffic).  Between the two lists I
 have over 19000 conversations (which can each have a large number of
 individual mails).  Mail.app on the mac and thunderbird had problems
 dealing with that much stuff if I wanted to search through them, but
 gmail's search is pretty much instantaneous.  I've found it's much
 faster to just search my e-mail account than to try and search the
 list archives too. :)

Re: [Flashcoders] Fwd: Timeline label question

[Andy Herrman]

I haven't seen the book so this is completely a guess, but is it
possible he wants the actions in frame 1 to happen before the loading
display (maybe some pre-loading initialization) but the actions in
frame 5 need to happen after the loading display has been shown?

Hi,

I saw something in Colin Moock's book Essential ActionScript 2.0 and I was
wondering if someone could explain it.

In Chapter 11, he outlines an OOP application framework.  In the part where
he sets up the timeline in the .fla file, he attaches actions on frames 1, 5
and 15 (these frames are also keyframes).  However, the loading label
starts on frame 4 so it actually overlaps the actions associated with frame
1.

My questions:

1.  Why doesn't he start the loading label on frame 5 to correspond to the
actions that start on that frame?

2.  What is the effect of starting the label on frame 4 instead of frame 5?

Re: [Flashcoders] Local Connection / Intel Mac bug??

[Andy Herrman]

Is your situation the same as Jeff's?  Specifically, is one SWF
running in Flash 9 natively and the other running in Flash 8 through
Rosetta?  If so then I doubt they would be able to connect via local
connection.

My understanding of how Local Connection works is that it uses shared
memory (though I could be wrong).  This is something that probably
can't be done between something running natively and something running
through Rosetta, as they would effectively have completely different
environments.  It would be similar to running one flash movie in
windows, then running another one inside another windows running in a
Virtual PC instance and expecting them to talk to each other with
local connection.  True, they're running on the same machine, but
their environments are segregated.

If both your movies are running in the same environment then I don't
know why it wouldn't work.

Re: [Flashcoders] animating buttons

[Andy Herrman]

I haven't done animations so I can't really help you there, but as for
your other question:


* what's better practice: creating an emptyclip on the parent outside the
class and pass the empty instance in to the constructor, or pass the parent
in and let the class create an empty clip if needed?


I tend to do both. :)

Specifically, I usually have a constructor which takes in the movie
clip it should use as its root clip (the empty clip you mention), and
then have a static factory method which takes the parent clip, creates
an empty clip, and then constructs the class.  So, something like:

class MyClipWrapper {
 private var myRoot:MovieClip;

 function MyClipWrapper(root:MovieClip, ...) {
   myRoot = root;
   /* the rest of your initialization */
 }

 public static function createMyClipWrapper(parent:MovieClip, ...,
name:String, depth:Number):MyClipWrapper {
   if(depth == undefined) {
 depth = root.getNextHighestDepth();
   }
   var empty:MovieClip = parent.createEmptyMovieClip(name, depth);
   return new MyClipWrapper(empty, ...);
 }
}

Hi list,

when programming in AS2 i usually favor composition over inheritance, so eg
when i have a button i create a class for it passing in a parent container
and the class attaches all the objects it needs on the parent and wraps it.

However when i want to animate a number of these buttons with respect to
eachother in a startup animation for example, the composition thing tends to
make things more complicated then necessary.
I either need to:
* add a getInnerClip to the class so i can get the inner clip and animate it
in all kinds of weird ways (violating encapsulation), or
* I need to add a lot of movieclips properties/methods to the compositing
class (but maybe thats just the way it is), or
* put all the animation code within such a class, which doesnt sound that
good either

I was wondering what approach u guyz ussually take?

In addition with respect to the composition thing:
* what's better practice: creating an emptyclip on the parent outside the
class and pass the empty instance in to the constructor, or pass the parent
in and let the class create an empty clip if needed?
Im in favor of the first, since it doesnt allow to mess up the parent as
much as in the latter option, but again it involves a trade off of control.

The specific situation I'm dealing with is a visual object that consist of
an alpha shadow on a floor layer and the object causing the shadow on an
item layer. Clearly the shadow's and item's movement are related, so I would
like to wrap these two items in one class, and then use this single instance
in an animation where the whole thing is for example blurred based on its
speed.

 Making any sense?
thanks for your ideas!

 I'm having a tough time getting a simple LocalConnection connection

 Scenario: Flash 8, AS 2, two separate Flash projectors.

 Procedure:

 3) Project B initializes, then starts LocalConnection.send using
 connectionName from step A. No arguments are sent.
 4) Nothing happens, no onStatus calls are triggered either on the

 This is all occurring on the localhost sandbox, so I'm pretty sure I
 don't have to deal with security shenanigans. The code is all
 contained in static singleton classes, so the LocalConnection objects
 are class properties.

Re: [Flashcoders] factory with varying numbers of params

[Andy Herrman]

There are two ways I can think of to do this.  One would be to have
multiple factory functions, one for each type of object you want to
create.  The other would be to create a simple class (FactoryParams or
something like that) which stores all the parameters.  You pass that
as the parameter object, and you can have that parameter object be
strongly typed.

class FactoryParams {
 public var firstParam:String;
 public var secondParam:Number;
 public var thirdParam:SomeComplexObject
}

By using a class instead of a generic object you can keep the type
information (and if you use getters/setters instead of public
variables then you can even do validation on the values if you want).

 I don't want to attach the PostView to the PostModel class, I just

Could you set a watch on the variable?  I haven't done it, but my

Okay, so I have an FLA with a series of embedded movieclips:

I want a static function -- in an as 2.0 class -- that, when given

movieclip and it finds that clips ALMOST outermost parent.

Here's my class  function:

class com.research.StaticRecurse

if (mc._parent._name == garden)
{
trace(inside getOuterMostParent:  + mc);

and inside the fla, I use the following code:

import com.research.StaticRecurse;

var innerMostChild:MovieClip = garden.tree.branch.twig.flower;
var mc:MovieClip = StaticRecurse.getOuterMostParent(innerMostChild);
trace(outside getOutMostParent:  + mc);

the trace is as follows:

inside getOuterMostParent: _level0.garden.tree
outside getOutMostParent: undefined

As you can see, the first trace -- which works beautifully -- occurs
RIGHT BEFORE the return statement. But the value that's actually
returned is undefined. I've never encountered anything like this
before. To me, it seems as if I'm doing this:

function x():Number
{
  var n:Number = 1000;
  trace(n); //1000
  return n;
}

trace(x()); //undefined

... which would be insane. I'm guessing it's a scoping issue that has
to do with recursion and the fact that this is a static function
(which it kind of has to be). Why is this happening? Is there a
workaround? Thanks!

Re: [Flashcoders] AS2.0 Question - passing data between classes

[Andy Herrman]

getInstance() is usually used for accessing Singleton classes.  These
are classes of which only a single instance can exist.  This way any
class can call getInstance (a static method) to get the class, and
that class can store shared data.

Take a look at this:
http://en.wikipedia.org/wiki/Singleton_pattern
for an overview of singletons.  It's a very useful design pattern.

Re: [Flashcoders] Changing Green (halogreen) highlight color

[Andy Herrman]

I believe you can use the setStyle function to do it.  For instance,
in some of my code where I'm setting up a combo box I have this (I
forget which color setting actually changes the focus rectangle, but I
think it's 'themeColor'):

   comboBox.setStyle('themeColor', 0x007CBA);
   comboBox.setStyle('borderStyle', 'solid');
   comboBox.setStyle('borderColor', 0x6E6E6D);
   comboBox.setStyle('fontSize', 10);

Or, to turn it off I do:

   comboBox.drawFocus = null;

Re: [Flashcoders] Basic class for swf-question

[Andy Herrman]

The way I do it is to have a static main method in your mother class
that takes the root movie clip as an argument, and then in the first
frame of the movie do:

 main.class.package.MyFabFlashApp.main(this);

Most of the time that function is just something like this:

 public static function main(rootMC:MovieClip):Void {
   if(rootMC == undefined) { rootMC = _root; }
   // Set stage options here
   Stage.showMenu = false;
   Stage.scaleMode = noScale;
   Stage.align = LT;
   var myClass:MyClass = new MyClass(rootMC);
 }

wanted to put it anyway in case I've missed something. ;-) I've put my

want to move it into a class.

[Flashcoders] Why does this work?!

[Andy Herrman]

I just realized that there are a number of switch statements in my
code which probably shouldn't work, yet appear to, and I'm wondering
why.

Here's a really simple example.  I have a class that tracks the
connection state of my app, with the following values used as the
states (read-only attributes simulating constants):

 public static function get CONNECTED():String { return CONNECTED; }
 public static function get FAILURE():String { return FAILURE; }
 public static function get NOT_CONNECTED():String { return NOT_CONNECTED; }

In the code that lets you set the state to a particular value it does
a sanity check to make sure the state value is one that's expected
(since in theory the user could provide any string value):

 public function setConnectionState(cs:String):Void {
   switch(cs) {
 case ConnectionState.CONNECTED:
 case ConnectionState.FAILURE:
 case ConnectionState.NOT_CONNECTED:
   break;
 default:
   cs = ConnectionState.NOT_CONNECTED;
   break;
   }
   this._connectionState = cs;
 }

Now in Java switch statements must use constants for the case values.
You can do something like I just did, but the variables being
referenced must be declared final (so the compiler knows they won't
change).  There isn't any equivalent to this in Flash (I simulate
constants by doing read only properties), so why does the case
statement work?  Does flash actually execute the stuff after the
'case' keyword?  What happens if multiple of those things return the
same value (for instance, say both CONNECTED and FAILURE returned
foo)?

Re: [Flashcoders] preloader and cacheing problem

[Andy Herrman]

What's the value that replaces +file+?  That's where the unique
identifier would appear if there was one, but that would just handle
the preloader file.

If you have the FLA for the preloader movie then you should be able to
take a look at the code and see if it's appending a unique identifier
to the lager movie's URL as well.  You'll need to dig through the code
to find it, but look for things like 'loadMovie' or 'MovieClipLoader'

Hi John,

this shouldn't actually happen, unless the url to the SWF that's being
loaded in is modified to make it 'unique' each time the swf is loaded. That
can be done, for example, by appending a random number to the end, so you
get urls like myfile.swf?0.123347575.

This might have been the intention of the original developer, I guess.

Other than that, the swf should be cached. You could also post the loading
code, that might shed further light on the issue.

We have been supplied with Flash files that include a preloader, a small

bandwidth and it seems completely unecessary.  We have the FLA file and
although we are PHP, Javascript programmers, we have no experience of Flash

how we can set some conditional logic within the Flash preloader to only
fetch the rest of the Flash if it hasn't already been downloaded in that

Re: [Flashcoders] Why does this work?!

[Andy Herrman]

Oh, the code is OK, and it works.  I'm just surprised Flash lets you
have case statements with non-constant values.  Since the case values
are actually functions that are evaluated it's possible that you can
have multiple case statements of the same value.  I'm not used to
languages/compilers allowing those situations.

in AS2 you can create constants with the ASSetProgFlags global method :

 private static var __ASPF__ = _global.ASSetPropFlags( ConnectionState ,

ConnectionState is the name of your enumeration static class :)

For me.. your code is ok :

public function setConnectionState(cs:String):Void

Re: [Flashcoders] Make page ads refresh on Flash click events

Do they want the changes to happen while navigating within the flash

You'd just need to add to your navigation code to have it refresh the

Re: [Flashcoders] Little OT - USB drive autorun?

[Andy Herrman]

My understanding is that the U3 stuff requires specific stuff to be
implemented in the firmware.  The flash drive's firmware actually
simulates a CD-ROM along with the flash drive, and uses the windows
autorun feature for CDs to actually launch the program.  It won't work
on machines that have autorun turned off for CDs though.

I don't think there's any way to do it for random USB drives.

Re: [Flashcoders] double clicking on swfs to click button

[Andy Herrman]

Actually, to me it sounds like he's using Windows and is running into
the Eolas thing.

If that's the case, the problem is that, due to patent issues,
Microsoft had to change IE's behavior with ActiveX controls (which
Flash and Java both use for their plugins) such that they don't get
any mouse or keyboard events until you activate them by clicking on
them.

There are ways around it, documented in the MS whitepaper about it:
http://msdn.microsoft.com/workshop/author/dhtml/overview/activating_activex.asp

The easiest thing would be to use swfobject, as was mentioned in an
earlier post.

Re: [Flashcoders] creatTextField Help

[Andy Herrman]

Try throwing some trace statements in there to see if things are being
instantiated correctly.

Specifically, after the createEMptyMovieClip try:

trace(_root.Art_MC);

and after the createTextField() call, try adding this:

trace(_root.Art_MC[Art_Txt]);

It's possible something isn't being created and you've got some
undefined values.

You might also want to check out Xray (http://osflash.org/xray).  It's
helped me when having issues like this before, as you can look at
exactly what exists at runtime.

Re: [Flashcoders] Entities are Hell!

[Andy Herrman]

My guess is that you were just using the node itself instead of
getting nodeValue (basically using the toString() function).  If
that's the case then toString probably gives the raw data in the file,
while using nodeValue does the full conversion of the data in the
node.

nodeValue works! I don't even have to convert the special characters to

Next Question: Do you understand How/Why it works?

Thanks,

Re: [Flashcoders] flash database - very conservative connections

[Andy Herrman]

I'm guessing you're using the version of IIS that comes with XP when
running locally.  That version has a very low limit on the number of
concurrent connections it allows.  It's possible that you're hitting
that limit when running locally (Flash might not be completely closing
the connections or doing other weird things with them).  I've seen my
IIS setup get messed up sometimes where it would think it was always
hitting the limit, and I'd have to reboot.

Try running it faster to the point where you get the error, and when
you do try browsing to something served by that machine in IIS and see
if you can get to it.

It does work fine if I step through very slowly - 1 page access per 30s.


Its like the database is still tied up after the first access.

I assume that I have some permission or database setting set

The ASP pages close the SQL connection when finished
Conn.Close()

Any insights or help very greatly appreciated

Re: [Flashcoders] LocalConnection security

[Andy Herrman]

Generally I think it's a good idea to come up with unique (dynamic)
names for the local connections, but this requires sharing data
between the SWFs in some other way.  In my case they are both part of
web pages served from the same source, so I can populate a parameter
that's passed to both that gives the unique LC name, and then they use
that.  This solves the issue of having multiple copies running at
once.

As for the other issues, you might be able to come up with your own
authentication process to make sure it's the right 'george', but
otherwise I'm not sure how you'd fix 1 or 2.

I have a Flash 9 app (named fred), which loads a Flash 8 app

It seems that a LocalConnection is the typical answer to this, but I

fred is loaded from a private domain (my own), and george runs from a
highly public domain (like putfile).  Here are the problems:

I have a lot of control over fred, but the code in george needs to be
simple.

1. If fred makes a LocalConnection to listen to george (allowing his
domain), then any number of other apps, coencidentially loaded from
george's domain, can send crap to fred. -- Can I make fred verify that
it was george and not just some other schmuck SWF from george's site?
2. If another app on george's site makes a localconnection before george
gets loaded, it could trump george's ability to listen to commands from
fred.
3. If the fred+george app is loaded twice, the localconnections will
have already been in use, making them unable to make a connection in the
newly loaded copy.

...so, how can this be solved?  Is there a way to make LocalConnection
(or some other type of connection) talk only within the same Flash
player?  Is there a way to know what URL is sending data through the
LocalConnection?

Re: [Flashcoders] SWF Only Loads Once

[Andy Herrman]

If I follow that code properly you're adding a 'no-cache' value to the
headers.  I'm not sure if that's the right way to do it.

Try this.  Add some query parameter to the end of your URL that has a
unique value (like the current time in milliseconds).  So something
like:

http://server/path/to/file.xml?uniq=currentTime

The browsers will see that it's a different URL and will always
redownload it, but unless the server is specifically using that query
parameter it will just be ignored.

Re: [Flashcoders] Problem controlling multiple movies with one class

[Andy Herrman]

I bet the problem is path related.  If you have a holder movie that's
running, which is loading the 2 SWFs, then the paths to the config XML
files would be relative to the holder movie's path, not the SWFs your
loading (I'm pretty sure that's true).  Your base class is probably
using the same relative path to load it, assuming the current path is
the SWF's directory, though that may not be the case.

Maybe try adding a parameter to the loading of the movie that takes
the relative path to use?  For example, if your directory structure
was this:

mainMovie.swf
test1/test.swf
test1/config.xml
test2/test.swf
test2/config.xml

main movie would do somewhere in its code (pseudocode as my brain
isn't completely functioning yet):

var test1 = loadMovie(...);
var test2 = loadMovie(...);
test1.loadConfig('test1/');
test2.loadConfig('test2/');

Then your loadConfig function would prepend the path to the name of
the config file, allowing it to get the right one.

I have two sections of my app in separate swf files that have very

content is in an xml file called config.xml that I load into the core
class.   I attached the core class to the main movie clip in my fla.  I
then exported the 2 swfs, put them in their own folders, in which there
was a folder called config that held the config.xml that went with the
section. What I found is it would work fine when I loaded the first swf,
but when I loaded the second, it is still referencing the data for the
first movie.  So even though it was a different swf file, the content
was the same.  The swf were loaded into the same holder movie, so I
thought this might be the problem.  I changed my root movie ot created a
new emptyMovieClip each time a section was loaded, and delete the old
one, but that didn't solve the issue.  The only way I found around this
was to create two subclass files that extend the main class, overriding
the function that loads the xml file, and rename the xml files to be
specific to the swf.
My question is, is this normal behavior?  How can I get rid of the class
and/or data from memory so the new data will load?

Re: [Flashcoders] Re: attachMovie vs createClassObject

[Andy Herrman]

I think the root movie clip does extend UIObject, as createClassObject
works for me.  And the objects I'm creating aren't custom ones, but
things like mx.controls.ComboBox, so I don't have to worry about
symbol* variables.

I may have to look into UIObject a bit more.  I've been making some of
my own controls, but doing it using Composition, with the class that
handles the control creating (or being passed) an movie clip to use.
Maybe extending UIObject would make more sense.

  -Andy

On 3/24/07, Yehia Shouman [EMAIL PROTECTED] wrote:

createClassObject is defined in UIObject core object. I don't think it can
be called as a method of any movieclip. It also requires that you define

static var symbolName : String = linkageID;
static var symbolOwner : Object = com.myclass;


and at the end of the day It calls createObject which basically uses
attachMovie passing on the symbolName. Use it if your host mc is a UIObject
(inheriting from mx.core.UIComponent or mx.core.UIObject).

I use
var myInstance:ClassType=ClassType(mc.attachMovie(ClassType.symbolName
,instanceName,depth))

Sometimes, if there is any pending code in the draw method of the created
class instance, I wait for a frame using doLater.

I hope this helps

Re: [Flashcoders] QT in IE returning null value to flash

Hm.  I haven't used ExternalInterface at al (I'm stuck with Flash 7),

Re: [Flashcoders] Re: Previously working SWF fails when reloaded in IE

[Andy Herrman]

I've run into that before.  The issue seems to be timing-related.
When you reload the page the SWF isn't re-downloaded (since it's
cached), so it loads much faster, so some initialization stuff might
run sooner than they did the first time.

Here's how I fixed this (I run into it sometimes even on the first load):

Set the size of the canvas to 1x1 pixels in the FLA (at the very
beginning Stage.width and Stage.height seem to report this value, then
switches to 0, then eventually to the actual size).  Then, when the
movie loads set up an interval that runs every, say, 500 milliseconds,
which checks the size.  Once both the width and height are something
other than 0 or 1 then you know the Stage has been sized, in which
case you stop the interval and start running the rest of your code.

I'm using this method in a couple movies and it works really well.

For the archives:

I don't know.  Sometimes that's a valid reason to do things like that. :)

As powerful as being able to do that is, it's one of those features
of Flash that always scares me.  I tend to think in terms of having my
code being used by someone else, and I don't like the ability of other
people to mess with my stuff at runtime and potentially break my
invariants, though maybe I just have trust issues.

Then again, that ability is the *only* reason I was able to get code
someone else gave me to actually work...

var foobar2 = new Foobar();
var foobar3 = new Foobar();

foo.greet(); // hello
bar.greet(); // g'day
foobar1.greet(); // hello
foobar2.greet(); // hello
foobar3.greet(); // hello

// now, let's let foobar1 extend Bar instead...
foobar1.__proto__ = Bar.prototype;
foobar1.greet(); // g'day
foobar2.greet(); // hello
foobar3.greet(); // hello

// foobar1 now has lost any other methods and properties previously
inherited from Foobar

// let all instances of Foobar extend Bar
Foobar.prototype.__proto__ = Bar.prototype;
foobar1.greet(); // g'day
foobar2.greet(); // g'day
foobar3.greet(); // g'day

// foobar2 and foobar3 still inherit methods and properties from
Foobar, foobar1 of course doesn't unless you set it's __proto__ back
to Foobar.prototype

// now, add a generic object to the prototype chain:
var baz = { greet: function () { trace( how's it goin'? } };
foobar1.__proto__ = baz;
foobar1.greet(); // how's it goin'?

// foobar1 now can't do anything else but greet(), let's let baz
extend Foobar to give it back the other Foobar methods:
baz.__proto__ = Foobar.protoype;

Fun stuff, huh? However, I strongly recommend not to use this other
than for purely educational purposes. If you feel like you have to
mess with the prototype chain at runtime, odds are there is something
you're doing wrong, and you should rethink your design. It's also very

Re: [Flashcoders] Super and this

[Andy Herrman]

Oh, I don't even think of 'super' as any kind of identifier/variable.
I think of it the same way I think of '.', '[]' or even '-' (in C),
in that I think of it as an operator used to access something, not as
a reference.  'super.' is just the way to access the parent
implementation of a function, just like '.' is how to access a member
property.

What I like about the Lingo model is the simplicity that every object is a
clear 'thing' that can be seen and inspected. There's a certain elegance to
the ECMA system where *everything* is an object, but you lose the sense of
distinction between objects, properties and methods that you have in Lingo.
Using this particular issue as an example, what exactly *is* 'super'? It's
not an object in the same sense that our instantiated class is, it's a kind
of hidden layer of the class.

I'm not saying one system is better or the other (I started with Lingo, so
I'm more comfortable with it, but I like both).

Re: [Flashcoders] Does ByteLoaded/bytesTotal work loading from CDROM ?

Then it's probably completely loaded.  When using local media the load
times will be very fast, unless the file is very large (on the order

Re: [Flashcoders] Super and this

[Andy Herrman]

So, when you instantiate a class that extends other classes, there is
only one actual object that's created.  So `this` would always return
the same object, whether in code written in A or in B.

super is simply used so that you can reference the parent class's
implementation of certain functions (mostly useful when you override
things).  You're still running on the same object, it's just running
the parent's implementation of the function.

  -Andy

On 3/16/07, Danny Kodicek [EMAIL PROTECTED] wrote:

Just a quick check, as I'm more used to Director's inheritance model than
Flash's!

I have an object A which extends B, which in turn extends MovieClip

Object B has a method 'fGetElementAt' which returns a movieclip
In A, I want to extend this by adding some extra code on top:

(leaving out declarations etc in the following:)

function fGetElementAt(tX, tY) {
tRet = super.fGetElementAt(tX, tY)
if (tRet == this) {
doSomethingElse()
}
return tRet
}

and the superclass version, just for sake of argument (obviously it's more
complicated than this):

function fGetElementAt (tX, tY) {
return this
}


My question: will the 'this' parameter refer to the same object in the
superclass as it does in object A?

Just to show where I'm coming from, to those who know Lingo, here's an
equivalent:

on mGetElementAt me, tX, tY
tRet = ancestor.mGetElementAt(tX, tY)
if (tRet = me) then
doSomethingElse
end if
end

and the ancestor version (again for the sake of argument)

on mGetElementAt me, tX, tY
return me
end

In this version, the if statement in the subclass would fail because the
variable 'me' refers to different objects in the two cases. In Lingo, I can
avoid this happening by using

tRet = callAncestor(#mGetElementAt, me, tX, tY)

instead. So is super.function more like ancestor.function or more like
callAncestor(function)?

Hope that makes some sense!

Re: [Flashcoders] Resizing sw, dependently on screen resolution

[Andy Herrman]

You can tell Flash to not scale the contents of the movie when it is
resized, so you should be able to just set the object tag values to
the size you want.  Try putting the following in the first frame:

Stage.scaleMode = noScale;

That will tell it not to scale things.  Then, when the window resizes
the contents won't scale.

Hi,

I want to extend a gallery slideshow script
(http://flash-creations.com/notes/dynamic_slidingviewer.php). It should
just contain the slide thumbs, but bigger. This is not the problem. The
problem is, that I want to have different swf width values, dependently
on the users screen resolution.

The container for the images should change. For examples, with a screen
resolution of 1024*768 Pixel, the container for the images should be
900*300 Pixel. With a bigger resolution, the width value would increase.
The images itself should not change in size. So with a bigger
resolution, I see more images on screen. With a lower resolution, I have
to scroll more as I seee just 2 or 3 images.

My problem: How can I change the swf width size dynamically? Of yourse I
could set the object tag values dynamically, but this would just stretch
it. I would like to avoid using a swf file for every screen resolution.

Do you know a smarter solution?

Kind regards,

Re: [Flashcoders] FAMES and flashout

I haven't used FAMES myself, so I can't really give you a whole lot of
help, but I do vaguely remember something like this from when I was
looking into it.

One of the tutorials I saw about getting flashout set up was that the
class it generates has problems with the latest version of MTASC.
There was something about having to go into that file and replace all
instances of TRACE with trace.  Since you seem to be having
problems using TRACE, maybe that's the culprit.

Here's the tutorial I was looking at:

[Flashcoders] Flash training suggestions

Weird, my e-mails keep bouncing for this thread.  Let's try again:

Actionscripting knowledge is about all I do have.  I've been working
on a fairly complex Flash application for the past 6 months or so (our

the programming stuff, but the design stuff like timeline and such I
don't really know much about.

One other thing I forgot to mention is that I'm also looking at
possibly doing FMS training.  However, the FMS application development
training courses all have prereqs of the FMS Video course, but I'm not
doing any Video related stuff with FMS so that course wouldn't really
be relevant, though I'm worried that I might have trouble with the FMS
course if I didn't take it.  Any suggestions there?

Re: [Flashcoders] Flash training suggestions

[Andy Herrman]

Oh, I completely agree about staying away from timeline actionscript.
The first little flash app I did (just a small test app) used the
timeline cause I didn't know any better, but I very quickly realized
that was the wrong way to go. :)

So, the book looks like it's one of the many explaining Design
Patterns books out there.  I feel like I've already got a pretty good
grasp on the language-agnostic application design stuff (including
design patterns).  I've been doing a lot of work in Java and some in
C++.  So right now I am looking for Flash-specific stuff.  I'm
inheriting a flash application that does some fairly complicated stuff
(with even more complicated things to be added in the future), and I'm
mainly running into not knowing how some things are done in Flash
(mostly UI and communication related, but also basic FMS management
stuff), or what all its capabilities are.  I figure the more I know
about Flash's capabilities and APIs the more effectively I can apply
the experience I have from other work I've done.

 one training course in the near term, and for what I'm doing the
 advanced class would be much more useful, but I'm not sure if I would
 have trouble in it due to not knowing the design stuff.

 Has anyone here been in a similar situation and found training that
 was helpful without duplicating a lot of what you already knew?  Does
 anyone have any suggestions on training courses that would be good, or
 even just training companies that people have found to be good?

 Thanks!

[Flashcoders] Re: gotoAndStop problems with swfmill

[Andy Herrman]

I think I found the difference.  Using swfmill's swf2xml mode and
looking at the differences between the swfmill SWF and the Flash IDE
SWF I see this:

The PlaceObject tags in the swmfill SWF have the 'replace' value set
to 0, while in the IDE's SWF the 'replace' value is set to 1.  I'm
guessing if I can make swfmill set that to 1 it will work, but I'm not
sure how to do that through the simple XML format.

Any ideas?

I'm having a weird problem with using gotoAndStop/gotoAndPlay when
using an SWF output by swfmill.

I'm trying to implement a class that uses movie clips created in
swfmill as button states.  The SWF generated by swfmill will contain a
clip for each button, which contains 4 frames, one for each button
state.  The button class will detect which state it should display,
and do a 'gotoAndStop()' for the frame that represents that state.
Fairly simple stuff.

Here's the problem.  If I try to change to a state that's defined
before the state it's currently displaying it doesn't work, unless I'm
going to the very first frame.  It keeps displaying the last frame it
displayed.  However, if I use an SWF with the same data, but generated
by the Flash IDE it works perfectly.

Probably easiest to explain if I just give you my code.  here's the
swfmill input:



?xml version=1.0 encoding=iso-8859-1 ?

movie width=320 height=240 framerate=12 version=7
  background color=#ff/

  clip id=upState import=up.jpg/
  clip id=downState import=down.jpg/
  clip id=overState import=over.jpg/
  clip id=disabledState import=disabled.jpg/

  frame
library
  clip id=testButton
frame name=Up
  place id=upState depth=1/
  stop/
/frame
frame name=Over
  place id=overState depth=1/
  stop/
/frame
frame name=Down
  place id=downState depth=1/
  stop/
/frame
frame name=Disabled
  place id=disabledState depth=1/
  stop/
/frame
  /clip
/library
place id=testButton name=testButton depth=1/
textfield id=log width=200 height=50 size=10 font=vera
  text= x=0 y=30/
place id=log name=log depth=10/
  /frame
/movie



And here's my test code that reproduces the error:


class Main {
  public static function main(mc:MovieClip):Void {

var iObj:Object = new Object();
iObj.testButton = mc[testButton];
iObj.log = mc[log];
iObj.count = 0;
iObj.setMode = function(mode:String):Void {
  this.log.text = mode;
  this.testButton.gotoAndStop(mode);
}
iObj.func = function():Void {
  switch(this.count++ % 7) {
case 0:
  this.setMode(Up);
  break;
case 1:
  this.setMode(Over);
  break;
case 2:
  this.setMode(Down);
  break;
case 3:
  this.setMode(Disabled);
  break;
case 4:
  this.setMode(Down);
  break;
case 5:
  this.setMode(Over);
  break;
case 6:
  this.setMode(Up);
  break;
  }
}
iObj.interval = setInterval(iObj, func, 1000);
  }
}


I generate the SWF by doing:
swfmill simple test.xml test.sw

and I compile the code with:
mtasc -swf test.swf -main main.as

The state changes work fine until it hits case 4.  The Down (4) and
Over (5) cases just keep displaying the Disabled state.

Again, if I replace the swfmill output with the output of the Flash
IDE, making the same thing, it works fine.  The only thing I can guess
is that the frames I created in the IDE were created using Insert
Blank Keyframe, but I don't know if that really has any relevance.

Anyone run into something like this?  Am I just missing something
simple in my swfmill XML that would fix this? (I couldn't find any
good reference on the swfmill XML format, so I might just be missing
something).

Thanks!

Re: [Flashcoders] AS3 parseFloat issue?

[Andy Herrman]

I think the problem here is that this:

var n2:Number = parseFloat(n2Split[0])*Math.pow(10, parseInt(n2Split[1]));

is not the same as doing the math.  When you define it as a string the
code will convert the number directly, trying to get as close as it
can to the value.

However, in the code you have there you're not doing the same thing as
the string.  Math.pow is going to be using floats/doubles in order to
calculate the power.  The instant that happens you lose accuracy, so
before you even do the multiplication you've lost accuracy, so the
resulting number won't be the same.  So in fact, you aren't deriving
the same value.  This is the problem with floats.

Also, you try to do this to show that they should be the same:
trace(n1);//6.30e+51
trace(n2);//6.3e+51
trace(6.30e+51 == 6.3e+51);//true

However, n1 != 6.30e+51.

6.30e+51 is simply the approximation that Flash uses when
converting it back to a string.  It maxes out at a certain number of
digits after the decimal point, so the string representation isn't
accurate.  As your math later shows, there would be more digits way
back at the 36th position (where the first digit is the 51st
position).

I hope that helps to explain it a bit.

 You will have to write all of your own arithmetic or find a package
 designed to work with large numbers with high precision.

 There are probably ways to deal with this but ordinary float or double
 will not do it even in JVM. You may get one test to work but there is no
 assurance that with a different sequence of operations with different

Re: [Flashcoders] AS3 parseFloat issue?

[Andy Herrman]

Oh, and this:

parseFloat(n2Split[0])

also adds errors.  The number (6.3) probably can't be accurately
represented in float/double format, so it's not quite 6.3 (it might be
6.3005123412, for example).  So, when you then multiply it
by the power of 10 it won't be the same as when it was simply parsed
from the full string.

[Flashcoders] Flash training suggestions

[Andy Herrman]

Resending as this bounced the first time I tried (so if you already
saw this, sorry!):

I'm looking for some suggestions on Flash training classes.  My Flash
devel knowledge is in a somewhat interesting state in that I know the
basics and some advanced parts of AS2 programming, but don't really
know much at all about using Flash itself (timeline, creating UI
objects in the FLA, etc).

I've found a few training courses that I could go to, but the ones
that look useful to me (the more advanced programming ones) have
prereqs of the simpler classes, where most of the material is stuff I
already know, with just a few things that I don't.

For instance, this class:
http://www.trainsimple.com/courses/advanceddesign.html
has a lot of things I'd like to learn (Tween, extending MovieClip) but
has prereqs requiring both basic AS knowledge which I have and basic
Flash design stuff (Rich Content Creation), which I don't have.  I
don't know if I'd be able to get the company to have me take more than
one training course in the near term, and for what I'm doing the
advanced class would be much more useful, but I'm not sure if I would

Has anyone here been in a similar situation and found training that

Re: [Flashcoders] Flash training suggestions

[Andy Herrman]

Actionscripting knowledge is about all I do have.  I've been working
on a fairly complex Flash application for the past 6 months or so (our
Flash developer quit and it landed on me), so I've picked up a lot of
the programming stuff, but the design stuff like timeline and such I
don't really know much about.

One other thing I forgot to mention is that I'm also looking at
possibly doing FMS training.  However, the FMS application development
training courses all have prereqs of the FMS Video course, but I'm not
doing any Video related stuff with FMS so that course wouldn't really
be relevant, though I'm worried that I might have trouble with the FMS
course if I didn't take it.  Any suggestions there?

Re: [Flashcoders] preloader give

Re: [Flashcoders] clearInterval(0);

[Andy Herrman]

I would suggest initializing the interval value as NULL instead of 0,
since I think 0 is a valid ID.  That way you can be sure you don't
accidentally clear an interval that you don't want to.

Well actually, clearInterval(0) clears the interval ID 0

lets say you have an interval defined :

var myInt:Number = setInterval(this, doSomething, 1000);

then it is possible that myInt = 0.

The value of myInt is set by calling setInterval, which returns the ID
of the interval,
so doing clearInterval(0) is the same as doing clearInterval(myInt)

but otherwise it doesn't do anything if no interval ID 0 exists
