RE: [Flashcoders] AS3 Hi-Jinks : Call to a possibly undefined method
We're still working on the actual text of the error messages, and yes,
that one could certainly be a little less cryptic. Have you seen the
Error and Warning Codes appendix in the language reference? It
includes descriptions for some of the more common error codes:
http://livedocs.macromedia.com/labs/1/flex/langref/errorCodes.html
As for your particular issue, one thing to keep in mind is that Sprite
doesn't inherit from flash.display.Graphics, so your Test object doesn't
have a moveTo() method. What your Test object does have is a graphics
property that contains a Graphics object. So change:
this.moveTo(0,0);
to
graphics.moveTo(0,0);
And it should compile. For example, the following code draws a red line:
package {
import flash.display.Sprite;
public class MoveToTest extends Sprite {
public function MoveToTest() {
graphics.lineStyle(1,0xFF,1);
graphics.moveTo(100,100);
graphics.lineTo(200,200);
}
}
}
Thanks,
Francis

Subject: [Flashcoders] AS3 Hi-Jinks : Call to a possibly undefined
method
My Lord, I'm having a splendid time when AS3 - but some of theses
errors
are heinous...
Call to a possibly undefined method moveTo through a reference with
static type Test
So, I've got this class Test, which extends Sprite and is attempting
to
call this.moveTo(0,0)
I'm know that Sprite has a moveTo method - inherited from
flash.display.Graphics. So, I'm not seeing how this is possibly
undefined. And through a reference with static type Test? There is
nothing static about my Test class.
Any idears?
package {
import flash.display.Sprite;
public class Test extends Sprite {
public function Test() {
this.moveTo(0,0);
}
}
}

[Flashcoders] class instance and var getting overwritten
Hi all,
I am having a very odd issue with a class I made. What happens is that one
of a private variables declare in that class get overwritten when there's
more than 1 instance of that class. It seems that this var someObject is
common to all instances of the class. Which defites the purpose of classes.
this is a sample of the code that i am using.
import com.seb_lib.utils.Delegate;
class aclass
{
private var target:MovieClip;
private var someObject:Array = new Array();
public function aclass(target:MovieClip)
{
this.target = target
init();
}
private function init():Void
{
for (var i:Number=0; i7; i++)
{
someObject[i] =
{
name:undefined
};
target[c+i].onRelease = Delegate.create(this, handleClick, target[c+i],
i);
}
}
private function handleClick(mc:MovieClip, id:Number):Void
{
for (var i:Number=0; i7; i++)
{
trace(target + - + someObject[i].name)
}
for (var i:Number=0; i7; i++)
{
someObject[i].name = mc._name
}
for (var i:Number=0; i7; i++)
{
trace(target + - + someObject[i].name)
}
trace(**)
}
}
USAGE:
i then create 2 instances of the class where i am passing 1 argument which
is a mc. each of these mc contains 7 buttons (could be less but the class i
am using defines 7 buttons...).
import aclass;
var d:Array = new Array()
for(var i=0; i2; i++)
{
d.push(new aclass(this[wheel+i]))
}
OUTPUT:
-
i then trace what's in the someObject before the click and after the click.
as well as this i also output the parent mc of the button which was the
argument passed in the constructor.
from the output we can conclude that someObject is sort of common for the 2
intances... this is driving me nuts...!!! how is that possible, hey?
someObject is private and also I have 2 instances of that class so i should
also have 2 intances of someObject, one for each instance

Re: [Flashcoders] using prototypes -bad or good?
As2 compiles classes down to prototypes. So feature-wise and speed-wise it's the same thing for the player. Prototype allows slightly better tuning of your code (when to put this when not, how to name the getter/setter etc.) but it has little practical benefit. You can still mix prototype definition with intrinsic AS class shell to get AS2 benefits on your prototype code. AS2 is faster to develop, however, since it's less noise in the written code and better/stricter compiler. So up to you - for small projects it's the same. For larger projects AS1 would slow you down. One silly example. I rountrip code between HTML+JS and Flash+AS2. If I type alert() instead of trace() in an AS2 class the compiler says wait a min. There's no such thing as alert() ..?. In AS1 it just compiles it and when called fails silently :) saves precious seconds.

Re: [Flashcoders] Learn AS2 or AS3?
Well actually there's some difference in learning AS2 with, say, flash mx 2004 and learning it with flash 8. Not that the language is any different, but the API of flash 8 can be a bit more overwhelming (it's API is more OOP orientated than that of 2004), so perhaps start going through the stuff of mx2004, where one really only has to deal with the MovieClip class, and then goto 8 and start playing with the the .geom.* and .filter.* classes, I think the API of flash 8 is a bit of a prelude where we're heading to; AS3, where the movieClip class has been packaged as well, unlike in 8 (same with the color class, unOOP'ish in MX, and more complicated in the form of ColorTransForm in 8).

We are building a fairly expansive flash based application which utilizes Flash Comm Server and remoting as well as support for embedded media players outside of the flash app. We are deep enough into development to have begun initial QA testing and the initial cause for concern is memory usage shown by the browser containing the app. My question, what are the most highly recommended real time flash profilers being utilized?

[Flashcoders] Creating a compiled component or compiled clip?
We have created a calculator component for reuse but I am not sure if we should create it as a compiled clip or component due to the way it was built. On the stage we have a movieclip and inside of it it has multiple textinputs, buttons, radio groups and graphs. We didn't use a bounding box or create the layout using actionscript mainly because we want to be able to easily change the layout if need be. It has working inspectable properties. Should this be a compiled clip or component? We are exporting it as component right now and without delving too much into the cause of it yet, when we drag it from the components panel into a new blank project the layout is screwed up (graphics are moved around) and the components do not show up until we compile the clip.

var xmlPlaylist = new XML(); //setup a variable to hold the XML
xmlPlaylist.ignoreWhite = true;
xmlPlaylist.load( playlist.xml ); //load the XML file
xmlPlaylist.onLoad = function( status ) {
//trace(loading xml);
if ( !status )
trace( status );
var entries = this.childNodes[0];
for ( var i = 0; i entries.childNodes.length; i++ ) {
var entry = entries.childNodes[i];
for ( var q = 0; q entry.childNodes.length; q++ ) {
//trace (entry.childNodes[q] = +

//trace(myTime = + myTime + myName + myName + myParam = +

Except that documentation does not provide an example usage of the parameter
nor an example of converting conventional time notation (hh:mm:ss:ms) into

Re: [Flashcoders] Passing param to cuePoint object
Hi Steve,
I'm actually just starting out my research into how to use Flash 8's
embedded cuepoints to handle closed captioning. Needless to say,
documentation is rather weak right now.
Below is my working code for displaying the captions that I embedded
in the FLV file using the Flash 8 video encoder tool. It's not what
you were looking for in terms of merging the captions from an XML
file during runtime, but it does show how to get those captions while
the video is playing.
The biggest confusion for me was linking the netstream with the video
object. I did not realize that there is a new video object in Flash
8 and that's what you need to have on stage to display the video.
Here is what the help docs say about creating a new video object:
To display the video stream, first place a Video object on the Stage.
Then use Video.attachVideo() to attach the video stream to the Video
object.

Add an embedded Video object to the library by clicking the Options

New Video.
Drag the Video object to the Stage and use the Property inspector to
give it a unique instance name, such as my_video. (Do not name it
Video.)

import mx.video.*
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
player.attachVideo(ns); // player is the video object (not an
FLVPlayback) that I have on stage
ns.onCuePoint = Delegate.create(this, handleCuepoint);
ns.play(test.flv);
function handleCuepoint(infoObject:Object){

RE: [Flashcoders] Learn AS2 or AS3?
Hmm now I am confused:) Well as I work in the Flash IDE 100% mainly on games and CDROMs etc and the next version of Flash supporting AS3 is a long way off, I think I will go for the AS2 anyway. May as well read the book after reading it and as someone else pointed out, there are no books for AS3 yet. Thanks for your advice though.

RE: [Flashcoders] Learn AS2 or AS3?
Having read over AS2.0 and AS3.0 migration... http://livedocs.macromedia.com/labs/1/flex/langref/migration.html ... it feels very disconcerning for those like myself who have invested a fair amount of time in AS2.0 only to find out that to take advantage of Flash Player 8.5+, one has to make massive migration changes to their AS2.0 code. Take for example the MovieClip class. The methods that have been 'removed' show up frequently in a lot of what I have worked with like say 'attachMovie' This is an interesting thread cause I wonder about the future of AS2.0 if it has a future. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Pedro Furtado Sent: Friday, October 21, 2005 11:18 AM To: 'Flashcoders mailing list' Subject: RE: [Flashcoders] Learn AS2 or AS3?

Re: [Flashcoders] Learn AS2 or AS3?
- you do not have a timeline in AS3+flex2 Just to avoid confusion AS3 still fully supports the timeline, and if you load clips with frames that were compiled in Authoring you can still use goto, stop and all other timeline methods, properties and events. It's Flex which avoids the timeline, but this was the case even when Flex compiled AS2 code. The next authoring which will have AS3 support will still have the same timeline as before (or better :) ). ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

AS1 and AS2 and AS3 all compile to Flash Player byte-code. The VM could not care less how you created the byte-code. You could define your own language and write your own compiler to generate an swf. Sort of true, but misleading. AS1(2) bytecode runs in the old VM, and AS3 bytecode runs in the new VM, and the different VMs *definately* care how your code was created. AS1 bytecode will not run in the new VM and AS3 bytecode will not run in the old one. This is a kind of clean break for Flash. Not as clean as I would like, since having 2 VMs causes bloat, but clean in the sense that the new VM is incompatible with the old one because of the fundamental changes in the way the player works. ryanm ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Undefined and null in Flex2
Hi Robert, Gordon Smith from Macromedia posted this to another list a while ago. I am reproducing it with his permission. Hopefully it will clarify things a bit: Note, that this applies only to AS 3, not to AS 2 *** 'undefined' is basically legacy baggage in AS3 that must remain for ECMA-262 compatibility. Type Object is the ONLY type that can store the value undefined. It can also store the value null... it can store anything! Some but not all other classes can store null: A derived class like Button can store null but not undefined. String and Array can store null but not undefined. Number can store NaN but it can't store undefined or null. int and uint can't store NaN, undefined, or null; they only store integers like 23. Boolean can't store undefined or null; it only stores true and false. Since Object is the only type that can store undefined, if you try to set a var of another type to undefined, it will be coerced into something different. For example, setting a Number to undefined will coerce it to NaN. - Gordon * Spike On 10/21/05, Robert Edgar [EMAIL PROTECTED] wrote: AFAIK null and undefined are the same thing in F7/8 and can be used interchangeably Conceptually however we tend to think of 'undefined' and 'defined but has a null value' as two different things.

Re: [Flashcoders] Learn AS2 or AS3?
I've spent a fair bit of time this week helping people who are trying to get their Flex 1.5 apps working in Flex 2. Some of those apps worked with only a tiny tweak here and there and others will pretty much require a total rewrite. What I'm finding is that there is enough difference between what you *can* do in AS 2 and what you *must* do in AS 3 that it's probably better to learn AS 3 and use as much of those principles and syntax as possible when creating AS 2 apps. That way your AS 2 apps will still work and you'll have minimum pain if and when you port them to AS 3. FWIW, the apps that were easiest to convert were what I would consider well designed in an OO sense. Each file did one thing and only one thing. Each file was well decoupled from other files and well encapsulated. I'd like to think that's just because OO is a good thing, but I suspect that it's got as much to do with the fact that AS 3 is stricter about OO concepts than AS 2 was.

Re: [Flashcoders] Learn AS2 or AS3?
Strictly speaking the VMs care an awful lot about what they get, but you can use any tool you like to create a swf that conforms to what the VM requires. Creating an ActionScript compiler that generated java bytecode is certainly possible, but would have the same problems. You'd have to make sure that the resulting Java bytecode was compatible with whatever JVM you were planning on running it on. Spike On 10/21/05, Ron Wheeler [EMAIL PROTECTED] wrote: Interesting. Strickly speaking VMs do not care. You can use MTASC or Swish or MMC or your own program to create the code. The player will execute the code that it gets. If you have 2 VMs supporting 2 different byte-codes (AS2 and AS3) then you really have 2 products and only the branding (Macromedia Flash) makes them similar. If someone wanted to make an Actionscript compiler that generated Java byte-code, there is no reason why that could not be done.

Yes but in term of logic from a programmer point of view You do not need to understand the timeline concept to build a web application Which is also good imho Right now, a C#/Java programmer willing to code AS2 would had to understand the timeline concept as soon as he want to code over a GUI people coming from AS2 can sure still reuse their knowledge of the timeline concept, and this can even give them some more depth understanding of how the things work under the hood but if you look just at the logic, AS3+Flex2 do not need a timeline, and this influence a lot of things, especially building visual component It had been years that I waited the way things are done now in Flex2 But well I could even go in more details just comparing how AS2 use import (as it was a simpe #include) and how AS3 import Work totally differently, even if the syntax is exactly the same I can only tell to people thinking that AS2 is not different than AS3 To go read the doc http://labs.macromedia.com/wiki/index.php/Flex:Release_Notes take prog_actionscript3.pdf read it, and compare to how things are done in AS2 zwetan ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
RE: [Flashcoders] Flash Profiler
Same here. I recently did a pretty thorough search for a swf profiler... The best solution I could come up with was good ol' fashioned unit testing. If you know the common memory wasters in Flash and you've developed following object oriented design principles you should be able to narrow down the culprits pretty quickly. My method using Windows task manager ended up something like this: 1) Note how much memory a iexplore.exe consumes when playing an empty swf. 2) Watch memory consumption as you click through the app. When memory spikes, determine what objects were instantiated with that event. 3) Remove those objects one at a time from the project, recompiling and testing each time. When you remove one that makes the memory usage drop significantly, you've found an object that may need some refactoring. Anyone else got a method they like? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Rorex Sent: Friday, October 21, 2005 1:50 PM To: Flashcoders mailing list Subject: Re: [Flashcoders] Flash Profiler On 10/21/05, Kevin Bachman [EMAIL PROTECTED] wrote: We are building a fairly expansive flash based application which utilizes Flash Comm Server and remoting as well as support for embedded media players outside of the flash app. We are deep enough into development to have begun initial QA testing and the initial cause for concern is memory usage shown by the browser containing the app. My question, what are the most highly recommended real time flash profilers being utilized?

Re: [Flashcoders] Learn AS2 or AS3?
If you have 2 VMs supporting 2 different byte-codes (AS2 and AS3) then you really have 2 products and only the branding (Macromedia Flash) makes them similar. The renderer both VM use is still the same (there are no two renderers), also each VM has separate API but both share a lot of code (ex. XML DOM parsing). Also it's not two different products when it's all in one single binary having both VM's :) I kinda wished at one time that Flash 8.5 would split into another plugin without AS1/2 support, but anyway Macromedia knows better. Also cutting compatibility just to save few kbytes isn't worth with the kind of machines and network we have today. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Calling it legacy seems to contradict the current AS3 docs..
For example I think it is getStyle that is documented to return undefined if
the style property doesn't not exist, it then goes on to say that the
undefined it returns is NOT the same as null (undefined!=null).
So I take from that that undefined far from being legacy is alive and well
and activley used by MM in AS3...
Of course could be then docs are wrong or will change.
I note the comment about how it only applies to Object though and understand
how when assigned the value will be coerced, thanks.
It seemed to me that the docs were effectively setting a recommended
practice that for generic getAnyProperty type of functions they should
return undefined for undefined values rather than as at present return
null(because currently undefined==null).
I am somewhat confused now if MM regard undefined as legacy i.e. deprecated,
should we being returning undefined or null.
Also given that undefined!=null makes me wonder..

Does this work differently in AS3 dependent on whether x is undefined or

'undefined' is basically legacy baggage in AS3 that must remain for

Type Object is the ONLY type that can store the value undefined. It can also
store the value null... it can store anything!
Some but not all other classes can store null:
A derived class like Button can store null but not undefined.
String and Array can store null but not undefined.
Number can store NaN but it can't store undefined or null.
int and uint can't store NaN, undefined, or null; they only store integers
like 23.
Boolean can't store undefined or null; it only stores true and false.
Since Object is the only type that can store undefined, if you try to set a
var of another type to undefined, it will be coerced into something
different. For example, setting a Number to undefined will coerce it to NaN.

The reason I posted that particular item is that AFAIK Gordon is one of the

If there's a disagreement between him and the documentation, my money's on
him every time.
Having said that, this stuff is all likely to change and may not be true in
future betas or the final release, but it should be right for the public

Unfortunately I don't know enough to answer your questions with any degree

In AS3, an undeclared var or property has a value of undefined. A
declared var or property which has not been assigned a value has a
default value of null.

This is an alpha, so there are probably still some inconsistencies in
