Re: [Flashcoders] RE: Flash speech-to-text
This is how you record sound: http://www.getmicrophone.com/?p=69 If you're asking how to convert sound waves into speech, dude, what? Do you realize how challenging speech recognition is? Wait, why am I asking you this? If you did, you wouldn't be asking people on a Flash list how to do it, as if it's some piece of code somebody can copy and paste or a few links that will tell you the secret formula. Most speech to text programs are based on the Hidden Markov models. In speech recognition, the hidden Markov model would output a sequence of n-dimensional real-valued vectors (with n being a small integer, such as 10), outputting one of these every 10 milliseconds. The vectors would consist of cepstral coefficients, which are obtained by taking a Fourier transform of a short time window of speech and decorrelating the spectrum using a cosine transform, then taking the first (most significant) coefficients. The hidden Markov model will tend to have in each state a statistical distribution that is a mixture of diagonal covariance Gaussians which will give a likelihood for each observed vector. Each word, or (for more general speech recognition systems), each phoneme, will have a different output distribution; a hidden Markov model for a sequence of words or phonemes is made by concatenating the individual trained hidden Markov models for the separate words and phonemes. There you have it. That's a high level overview of speech to text. Do you understand anything in that paragraph? Probably not. Unless you're willing to study and put in the time to figure out how to do this, you're not going to figure it out. Nobody is going to point you in the right direction because this is a very niche knowledge area and none of these people are on Flashcoders. They're at universities working on their doctorates or working for the military or government, or some private company and they're not sharing this information. This is the stuff patents are made of. So either give up now (because what you want is some easy solution and there isn't one) or start doing real research, learn some serious Calculus, become an expert on on sound, speech, waveforms, and then figure out how to port all of this into Flash, which, in all likelihood, lacks the performance to actually achieve this. You'll probably have to do it on the server, passing the sound to the server as an mp3 file, and then pass the text back. That's the only thing I can think of that would possibly be able to do this. Prove me wrong. If you pull this off, you could probably build an entire company around your technology. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] empty XML Attributes..
hasOwnProperty does not tell you whether it has a length, though. It only
checks for existence.
And for some reason, it looks like you modified my code when quoting me:
>> if (node.hasOwnProperty("instance").length() > 0)
I didn't write that code, which would error since a Boolean doesn't have
length().
I wrote this:
if (node.attribute("instance").length() > 0)
Which not only works, but is the recommended way of writing this code by Adobe
themselves directly from the E4X documentation.
You're suggesting to write more code to do the same thing. Why should anyone

Re: [Flashcoders] spacing horizontal dynamic xml menu textfields
As I described on my forum post, you have to first put your items in an array.
var items:Array = [all, of, your, items];
var len:int= items.length;
var i:int;
Then, you do the following measurements:
// the right of the last item minus the left of the first item
var availableWidth:Number = items[len - 1].x + items[len -1].width - items[0].x;
// the total widths of all the items
var totalWidth:Number = 0;
i = len;
while (i--)
{
totalWidth += items[i].textWidth;
}
//Subtract the totalWidth from availableWidth to get the remainingWidth
var remainingWidth:Number = availableWidth - totalWidth;
// Divide remainingWidthby the number of items
var gapWidth:Number = remainingWidth / len;
// iterate through your array setting the x positions
// of the items based on the previous item's width and the gap.
var lastX:Number = 0;
for (i= 0; i < len; ++i)
{
items[i].x = lastX;
lastX = items[i].textWidth + gapWidth;
}
// That's all there is to it.

Writing readable code > writing less code.
That is what it comes down to. Most coders can understand both of the
following:
if(myObj){;}
and
if(myObj != null){;}
I would opt for the latter method always, as otherwise you are relying on
renderer specific logic to handle the conversion, as opposed to explicit
conversion.
I have actually spent an hr trying to debug an IE specific JS error, only to
find that even though implicit type conversion was working in other
browsers, it was throwing an error in a specific version of IE.
By your argument of less code > more code, this:
public function outputList():*{;}
would be better than
public function outputList():Array{;}
and AS2 would be better than AS3 on the whole basis that you didn't have to
typecast anything.
Just because a certain environment can convert types for you, doesn't mean
that you shouldn't typecast or not hint as to their object type in your
code.
Personally, I can type faster than I can think in code. I type really fast,
and I think code really fast, and typing out the extra 10 characters doesn't
hinder my productivity, it probably enhances it.
If you want to take the implicit convesion route, by all means I am not
going to stop you or object. However, I do and will always believe that it
is better for other people reading/working on your code that you do spell it
all out, use line breaks when it makes sense, and typecast all your
variables.
I think Dave's point was that you seemed rather authoritative, and this is
really a subjective matter.

Re: [Flashcoders] mac vs pc
The act of writing Actionscript in FlashDevelop is, IMO, better. FD's code completion and code gen is easier and faster. Because code completion and code gen is the majority of what I do from moment to moment as I'm writing, it's the better tool. Refactoring and debugging are not what I spend the majority of my time doing. I have Flex Builder. I use it sometimes, but not always, and generally I use it with Build Automatically turned on while I code in FD on the same project and it will spot compile-time errors on the fly. FDT is a great (albeit expensive) tool, but for day to day coding, I prefer FlashDevelop because it helps me write code faster. It might not help me debug faster, but I spend a lot less time doing that than actually writing code, which is where FlashDevelop shines. I'm confused by all these comments about the strength of the refactoring tool being a deciding factor. Do you really move stuff around packages that often? Do you really rename entire classes that often? I find that thinking ahead solves that problem, and when it comes up, Find and Replace in files does a great job, even if it's a few Find and Replaces instead of just one Refactor command. Believe me, I (and many others) have asked the FD guys for this feature, and it's something they're working on adding. However, it's not something I use often enough to outweigh the benefits FD provides when actually writing code. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

So I check if the "stage" property is null for almost all cases now.

writing more code to write the same code. You're going to write addChild either

Good question! But first, I should correct a minor misperception. It's not a matter of a slow hosting company, or a slow server - the current server is fast enough to handle the load it gets, and there's plenty of bandwidth at the ISP. I subscribe to groups on both Google and Yahoo, and generally see my posts just as quickly from chattyfig as with those groups. Obviously, your mileage may vary, but there you go. That said, if it were entirely up to me, I would have switched to Google Groups. I'm a big fan of Google services in general - Fig Leaf is a Google Enterprise partner, we use Google Apps for email, calendaring and information sharing, etc, etc. However, we run a number of lists, not just Flashcoders. There are about a dozen different lists. Some of those lists have some actual business value for us, as a channel for our expertise and for advertising our services. Flashcoders really doesn't at this point, if it ever really did at all. When these lists were set up long ago, they were set up using mailman. Mailman stores user lists and other data in a non-text format: Python qpickle files. When the Flashcoders list broke, I had absolutely no familiarity with this, and so had no way to export users from Mailman to Google Groups. I did, on the other hand, have a shiny new server that wasn't doing anything else, so the path of least resistance was to set up Mailman and just move everything over. Out of all those lists, Flashcoders was the only one with which I had any problems. Because Flashcoders' files were corrupted, and I didn't know Python, I had to manually extract information from the qpickle files. The other lists ran fine the whole time, and I could migrate them without any trouble. But I sure did run into trouble migrating Flashcoders for a variety of reasons, and got a bunch of flak from subscribers who didn't know how to unsubscribe, etc. So, in conclusion, if I woke up tomorrow and this was on Google Groups, I'd be perfectly happy. But that would require current subscribers to subscribe to that on their own.

Re: [Flashcoders] Slow emails
Kerry, My email was a matter of fact one, nothing more. It had nothing to do with the quality of the posts, members or owner. Flash Tiger emails show up very quickly because they're on Yahoo servers. Despite their recent financial troubles, Yahoo has a ton of servers on very fat pipes. By contrast, Flashcoders is hosted by a smaller company than Yahoo. For some reason, this host delays emails by minutes, and sometimes much longer. Moving to a faster host is probably either too expensive or time consuming (backing up the archives, etc.). It's not like the delay is that bad, but it does exist. I sometimes wonder why Flashcoders isn't hosted on Google Groups like AIR-TIGHT or Yahoo Groups like Flash Tiger. As you well know, Flash Tiger was created because Flashcoders was down for over a month. Years of the Flashcoders archives were lost to the ether because of a server failure. Flashcoders was created during a time when Google/Yahoo groups did not exist. No slight to Dave, but maintaining your own public email list is a 1.0 mentality. There are great services like Yahoo and Google groups that offer more features than a self-hosted solution without the cost or headaches. When was the last time Google groups went down? Google groups has a team of people available around the clock making sure it's up, so if it goes down, it's not down for long. With Flashcoders, there's just Dave maintaining it. When it goes down, you have to hope he's awake and not busy.

Re: [Flashcoders] FlexBuilder 3 auto-complete vs. FlashDevelop
In FlexBuilder, they don't start appearing as auto-completion hints as you type. You have to hit CTRL+SPACE. This is not a "mere" difference. You have to stop writing code to get auto-completion. Even worse, it's not "live" which means it breaks your natural flow. In FlashDevelop, you can hit space, return, period, open parentheses, open bracket, or any non-alphanumeric character and it will auto-complete. In FlexBuilder (and AFAIK, FDT) only return works. Here's a simple example: var loader:Loader; In FlashDevelop, you type these exact characters: lo.l( And it turns into this: loader.load( In Flex Builder, you have to type this: lo CTRL+SPACE RETURN . l RETURN That's 3 mental "breaks". FlashDevelop's auto-completion is a natural flow and doesn't interrupt your typing, FlexBuilder's does three times. Let's quickly look at Flex Builder's example again in detail so I can really illustrate the mental break it causes. lo CTRL+SPACE RETURN . l RETURN First, you have to hit two keys to get the hint, and then one more key to accept the hint. Then, you type the period and then have to hit return again to accept the load function hint. That last return causes oad( to appear. The important part of that completion is the open parentheses. You are expected to type RETURN to type ( and that is a mental break. It's far more natural to type open parentheses because that's what your mind knows goes after a method name. Sure, SHIFT+9 is not as "easy" to type as ENTER, but that's hardly the point. This is about your mental flow as you type. One makes you "think" (three times), the other doesn't because it just makes sense. FlashDevelop's auto-completion allows you to access arrays and such easily, too. var array:Array = []; FlashDevelop: ar[ Ends up with array[ FlexBuilder you have to type: ar CTRL+SPACE ENTER [ Lame. On top of that, if you make a typo in FlexBuilder or FDT, the hints go away. If you press CTRL+SPACE and there's a typo you get no hints. In FlashDevelop, typos are forgiven and code hints still show up, and again, "live" as you type. When it comes to auto-completion, the undisputed winner is FlashDevelop.

Re: [Flashcoders] FlexBuilder 3 auto-complete vs. FlashDevelop
It certainly does. It's simply using the mxml compiler to find those errors. The FD developers have stated their intent to include it one day, but have stated it's a lot of work. They currently have syntax checking. Keep in mind that FlashDevelop is two guys working in their spare time for free. jared stanley wrote: FDT does the auto-error check, which is so sweet - i read that FD doesn't have the ability to get that info, even with a plugin...

Re: [Flashcoders] FlexBuilder 3 auto-complete vs. FlashDevelop
FlexBuilder absolutely does NOT do auto-completion of class, instance and local vars (FD also does function names, etc.). I've never seen FDT do it, either, but that link obviously makes it clear that it is possible (though completely undocumented, not to mention that field doesn't look like it will accept 28 characters). It also says AS2, but does that work for AS3? Why on earth isn't this the default behavior? FDT costs hundreds of dollars, FlashDevelop is free. If you're on Mac, I guess it's the best choice available. Also, FDT is 100% project based. You can't just drag and drop an .as file on to it like you can with FlashDevelop (unless you already have one open). Plus, you don't get ANY auto-completion if the file isn't part of your project. Does FDT have a clone-file feature? ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] mac vs pc
FlashDevelop does do find and replace in files. FlexBuilder's "rename" function is very slow sometimes. FlashDevelop's Find and Replace In Files is nearly instant. Considering how infrequently one uses "rename" in FlexBuilder, it doesn't seem to offset the slowness of day to day coding with it compared to FlashDevelop. To fuel the fire a bit more, IMNSHO, Windows has MUCH better carat control than Mac. This makes writing code (and other documents) a lot easier and faster on Windows. As much as I love OSX (and I really do), Mac's inferior carat control is one of the things I find very lacking about it. The auto-complete mishaps with FD occurred in some (not all) of the beta releases, but now that it's a full release version, there are no longer any problems. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] FlexBuilder 3 auto-complete vs. FlashDevelop
Only FlashDevelop auto-completes in-scope member names and key words. Only FlashDevelop has smart auto-completion that forgives typos.

Re: [Flashcoders] mac vs pc
I'm confused why you would need to look at more than one project at a time, and you can switch projects very quickly in FD by using Recent Projects. It's well established the debugger is limited to tracing, which is generally good enough for most of the time. I don't know what you mean about better syntax and variable scope across documents. I find the variable scope feature of FlashDevelop to be fantastic. The F4 key is great. If you mean something else, I'm definitely interested. What plug-ins are you talking about specifically that Eclipse has that help with coding Actionscript? I agree the documentation is lacking. I've discovered new features on accident. I keep hearing about the refactoring feature, but how often are you refactoring and how does Find and Replace in Files (CTRL+I) not take care of it? In FB or FDT, if you make a typo, you lose it and you have to start over. This goes for properties and constants, etc. I don't know about you, but while I'm a great typist, I'm not perfect, and FlashDevelop is forgiving and still knows what you want, even if you typo or hit backspace to make a correction, where if you hit the wrong key or backspace in FB or FDT, you lose everything. This is especially a pain with long names. The getter/setter code gen for vars and the event code gen are incredible time savers. The default shortcut isn't very good, but you can change it (I use ALT+2). FlexBuilder and FDT offer live code compiling, which FlashDevelop does not. FDT's lexical parsing is superior to FlexBuilder, as well. However, I find that those features are not worth the speed tradeoff, and I can just compile anytime to see any runtime errors. FlashDevelop's syntax checking is generally good enough. Every developer I know that uses FlashDevelop for about a month can't live without it. Every developer that never has or hasn't learned the time-saving features it has (lack of documentation definitely doesn't help) doesn't really understand how much faster it is to develop in and if you don't have anything to compare it to, FlexBuilder and FDT are much better alternatives to coding on the timeline (ugh). ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] mac vs pc
I didn't say people who used it were retarded, I said the program was. The bottom line is, you can use Flex Builder to do your debugging if you need it, but for coding, which is what you spend the majority of your time doing, all the Eclipse-based Actionscript editors suck ass compared to FlashDevelop. If you make a typo in FB or FDT, you're screwed. You have to go all the way back to the period. In FlashDevelop, you're fine. It still offers you the auto-completion (is this what you meant?). FlashDevelop's class importing doesn't require you to type the entire package first. You just type the class name and the entire package appears no matter where the class is. And to the person who says that Flex Builder organizes your imports for you and FlashDevelop doesn't, that takes a few seconds ONE TIME for you to do in FlashDevelop (using the awesome CTRL+T shortcut that FlashDevelop has and FlexBuilder doesn't), whereas all the shortcomings of Flex Builder's auto-completion cost you a few seconds over and over constantly, plus added frustration. It's not even open to debate which one wins when it comes to time-savings and saved frustration. What you're talking about is an aesthetic, not a function, and it's easy to do in FlashDevelop. There is no comparable solution in Flex Builder for auto-completion and code-gen. The code gen in FlashDevelop is superior to Flex Builder. The auto-completion is superior. The class importing is superior. The workflow is superior. You can open any .as file without it having to be part of your project. If you really want the debugger, then use it for that. I keep Flex Builder open while I code in FlashDevelop for that specific reason. Code with the coding tool, compile with the debugging tool. Flex Builder sucks at coding, and is great at debugging. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] Re: SWAddress logical workflow
This is exactly how Gaia works. goto() calls setValue on SWFAddress and the response is dispatched to the framework to handle the navigation. Interrupts are handled in both loading and transitions.

Personally, I have not really thought about this in my stuff before, but the way you said you were approaching the SWFAddress bit seemed sensible to me - going a round- about way by setting the URL when you navigate in Flash then responding to the change via SWFAddress. This seems much "safer" because everything goes through a single route. There is a nice example of doing the dynamic thing with PHP in the SWFAddress examples. You can even tweak the whole site with Apache & mod_rewrite to get "pretty" URL's - this may / may not work with Zend AMF quite nicely so download and examine this example: http://www.asual.com/swfaddress/samples/seo/ which seems to be the smoothest one. If you are worried about fast clicking, have a look to see how an HTML site behaves with this - I guess you get half-assed page loading, etc. But people expect to wait a bit for something to load if they go back & forth, you just have to be prepared to "interrupt" what you are doing (I should probably take my own advice here and make sure my SWFAddress site behaves nicely) Hope this helps and if you come up with any interesting stuff, let us know!

Your sample doesn't show how you build the Array.

what Flash is telling you.
The reason it returns -1 is because indexOf couldn't find a STRICT
EQUALITY match for e.target.name in your array.
If you posted how you built buttonsArray, you'd probably solve your
own problem by looking at the code you wrote more closely.

It always traces "-1". This code should trace the index of the Array
element right? for ex: 0, 1, 2 or 3.
If i do this, it will trace the correct name of the element.
function buttonClicked(e:Event):void {
trace (e.target.name);
If I do this, it will trace the name of the second element:
function buttonClicked(e:Event):void {
trace (buttonsArray[1].name);
Why indexOf doesn´t work properly?

Re: [Flashcoders] XML find and delete nodes
Once you really dig into E4X and realize the crazy stuff you can do,
it's amazing.
I do some pretty crazy E4X parsing, filtering and validation with
Gaia. Here are some examples:
// get all nodes named page or asset in the entire XML
var nodes:XMLList = xml.descendants().(name() == "page" || name() ==
"asset");
// from those nodes, find any that don't have both id and src attributes
var invalidNodes:XMLList = nodes.(!attribute("id").length() || !
attribute("src").length());
// get all nodes where id is not alphanumeric or begins with a number
invalidNodes = nodes.(!(/^[a-z_][a-z0-9_]*$/i.test(@id)));
// this one is complex but basically it isolates nodes that do not
have a valid
// class package path in a package attribute
var packageNodes:XMLList = xml.descendants().
(attribute("package").length() > 0);
invalidNodes = packageNodes.(!(/^[a-z][\w\.]*\w+$/
i.test(attribute("package";

Re: [Flashcoders] calling an "event" function with a parameter that is a number
The latter is cleaner and better, IMO.
Write a function that your event handler calls. Then, you can call it from
elsewhere and from your button click handler.
function onThumbClick(event:MouseEvent):void
{
loadImage(event.target.name);
}
function loadImage(num:int):void
{
// loadImage(num);
}
Juan Pablo Califano wrote:
You have a couple of options:
You could add an optional parameter to the function that handles the click,
like this:
function clickThumb(e:MouseEvent,index:int = 0):void{
}
Setting a default value for the index parameter allows the function to be
called without passing it. That's what will happen when a thumb is clicked.
When you want to call the function directly, you'd do:
clickThumb(null,image_num + 1);
In clickThumb, check whether the event object is null or not. If it's not,
do what you're currently doing. If it's null, use the index parameter as the
index into my_images.
Another thing you could do is a bit of refactoring.
Have the click handler only resolve the index and calling another function
to actually load the image.
function clickThumb(e:MouseEvent):void {
loadImage(e.target.name);
}
function loadImage(index:int):void {
if (my_full_images[index] == undefined){
var full_url = my_images[inde...@full;

}
Then, from your other button's handler, call loadImage(image_num + 1);

Hello!
In my code there's a function that shows an image on the screen (or load
the
image and show a progress bar) that is called by clicking on a thumbnail,
and uses a parameter [e.target.name] refering to the property "name" of
the
thumbnail clicked, which is an integer. The thumbnails are placed inside
the
cointaner_mc MovieClip.
container_mc.addEventListener(MouseEvent.CLICK, clickThumb);
function clickThumb(e:MouseEvent):void{
if (my_full_images[e.target.name] == undefined){
var full_url = my_images[e.target.nam...@full;
etc...
but I want to call this function by clicking on a button, which would need
to pass another type of parameter, in this case, a variable which refers to
the number of the image displayed on the screen plus one.
I tried this:
clickThumb(image_num + 1)
But it doesn't work, I get the following error:
1067: Implicit coercion of a value of type Number to an unrelated type
flash.events:MouseEvent.
How could I call the function clickThumb and make it use "image_num + 1"
instead of "e.target.name" ?
Could I dispatch the event (MouseEvent.CLICK, clickThumb), passing this
value "image_num + 1" ?

Basically, I have a footer that is fixed to the bottom of a page and
for
the width of a page, so that no matter what size a user sets a window
for, it will always fix to the bottom. This is what I have so far
(using
AS3):
In my .fla, I have a long gray bar with the instance name "footer".
Then, over in my .as file, I have the following:

stage.addEventListener(Event.RESIZE, resizeHandler);
public function resizeHandler(e:Event):void {
footer.y = stage.stageHeight - footer.height;
footer.width = stage.stageWidth;
}
All of this works without a hitch. However, my problem arises when I
want to add text. If I add text in its own mc, then it won't adjust
with
the page. If I add text inside the footer mc, it will stretch with the
width of the page when I resize. So then I thought maybe I could make
them two mc's embedded in one main mc, and only define the width for
the
bar. That is, something like:
footer.y = stage.stageHeight - footer.height;
footer_bar.width = stage.stageWidth;
With "footer" as the main mc, and "footer_bar" as the long gray bar
embedded inside.
However, this results in a mess of errors.
Any ideas? This seems so common, I'm surprised I can't find anything
via
Google.

Re: [Flashcoders] Parsing HTML tags within flash from an XHTML file?
Do you mean you want to have links in your tags that call
Gaia.api.goto()?
You can do that, but obviously, those links wouldn't work in the XHTML.
After thinking about it a bit, I think what might work is this
Go to contact page
With that being the link to the SEO XHTML page that is generated for
that page.
In your parsing code, you would change the href to call an
actionscript method that would take page.html and convert it to
var href:String = a...@href;
href = href.substr(0, href.length - 4);
var internalTitle:String = href.toUpperCase();
Gaia.api.goto(Pages[internalTitle]);
That is just an example, but basically you're converting
"contact.html" to CONTACT and, there should be a public static const
in Pages called CONTACT which has the branch for that title.
Does this make sense? (this part of the question is definitely
appropriate for the Gaia forum, too)

public var textContent:TextField;
var myStyleSheet = new StyleSheet as StyleSheet;
var myURL:String;
var mySection:XMLList;
myURL = Gaia.api.getCurrentBranch();
myStyleSheet =
IStyleSheet(Gaia.api.getPage("index").assets.xmlCss).style;
textContent.styleSheet = myStyleSheet
for each ( var u:XML in mySection) {
if (myURL == u...@url) {
textContent.htmlText = u.copy;
}
Could I use this in tandem with my Gaia-produced XHTML pages? I do not
see where the actual node is included in the instance from the
demo site's XML, but only the url part. How is the rest of the text
being included?
Sorry to be impatient! I just did not expect this specific aspect of

Just so everyone is familiar with the context here, the above is the
thread on the forum about this.
The question is about how to use E4X to parse XHTML. I provide a code
example of how easy it is to do this, but Jonathan's question is more
of a general one about how to use E4X to parse nodes.
Flash doesn't support in its htmlText, so that's why you use E4X
to grab the node content like
var value:XML = XMLList(copy.innerHTML)[0];
var body:XML = value.div.(@id == "body")[0];
I believe the challenge for Jonathan is what the above lines of code
mean and how they work.
value is the XHTML.
value.div returns an XMLList of all div nodes on the first level
within the XHTML.
value.div.(@id == "body") means give me an XMLList of the div nodes
that have an attribute id="body".
valid.div.(@id == "body")[0] means give me the first XML node in that
XMLList.
This is how E4X works. A lesson on E4X is out of scope of my forum.
However, there are lots of resources out there for E4X in AS3. I
highly recommend Colin Moock's Essential Actionscript 3.0 book, which

And Jason, you do not need to complicate things with RegEx. E4X does
enough. XHTML is technically XML and can be parsed the same using E4X.
Also, while Flash doesn't SEEM to support newer HTML tags like
and for and , it actually DOES if you write css
to do it.
strong {
font-family: FFScala-Bold;
display: inline;
}
em {
font-family: FFScala-Italic;
display: inline;
}
In this case, I am using a bold and italic font to show them, and by
defining the node types in css (and setting them to display: inline),
it works like a champ!
Here's a detailed code sample:
http://www.gaiaflashframework.com/wiki/index.php?title=Runtime_Font_Loading#StyleSheet_Example
Now, I can keep my valid XHTML and use it directly in Flash. It's
really straightforward. The challenge is learning how to parse the
nodes using E4X, which, once you get your head around it (and it took
me a lot of experimenting to learn how awesome and powerful E4X is and
how to leverage it), you can do stuff like this easily.

Re: [Flashcoders] JSON Experiences
If your XML has namespaces (like YouTube's xml feeds), then, yes, JSON is easier to implement. Namespace support in E4X is the very definition of "Royal Pain In The Arse". It's why the AS3 code lib for YouTube uses their JSON feed instead. It's just too ridiculous to deal with all those namespaces. However, without namespaces, E4X is far more powerful than JSON, IMO.

Re: [Flashcoders] is imported db text safe from decompilers?
Encrypt your text using a super crazy encryption algorithm. Then, create a swc that contains the key and algorithm to decrypt the text. Then, encrypt that swc using another super crazy encryption algorithm. Load the swc at runtime as raw bytes, decrypt it in memory, and then instantiate it as the class you need. Decrypt the text. Null out the swf instance and the bytes. Force the gc to run. That's about as protected as you can get. Obviously, you'll need a pretty strong challenge response system in place to get the shared key to decrypt the swc in memory. Don't know how to do this?

Re: [Flashcoders] video seek ability
Here's what you need to know to make a good scrubber for progressive download FLVs. 1. You need a background that shows the entire width of the bar. 2. You need a progress bar that shows how much of the video has loaded. The width of this bar is the background.width * (ns.bytesLoaded / ns.bytesTotal); 3. You need a playback bar or shuttle which is updated on a timer. The width (bar) or position (shuttle) is the background.width * (ns.time / ns.metaData.duration). 4. You put the mouse events on the progress bar. On press, you set a flag that you're seeking (so the update doesn't move the bar/shuttle but does keep the progress bar updated), you pause the video, and you start a timer that calls an update function. In the update function, you track the mouseX and constrain the value (via Math.min and Math.max) to values between 0 and the progress bar width, to which you set the position of the shuttle or width of the playback bar. You take the position/width of the bar, divide it by the background.width, multiply that by the duration of the ns, round it, and that's your seek time. When you release, you unpause the video (assuming the video was playing when you pressed, you'll need to keep a separate flag for that). If you do it like I've described, then the dragging is always constrained by the current loaded amount, not the loaded amount at the time you pressed, and you don't get that ugly stutter when you stay in one place (there's no reason to not pause the video when scrubbing). ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] use get / set functions or make your own
For clarity, they're referred to as implicit and explicit.
get prop / set prop = implicit
getProp() / setProp = explicit
In AS2, it made a difference because implicits were available right away,
whereas explicits were not available for 1 frame. This limitation is not
present in AS3.
Basically, implicit implies properties of a class, whereas explicit implies
methods of a class.
I opt for implicit over explicit because this:
foo.prop = value;
makes more sense than
foo.setProp(value);
I leave methods for methods, not properties.
That being said, I don't abide by the retarded rule that you shouldn't have
public vars in a class. People who do this
private var _foo:Boolean;
public function get foo():Boolean { return _foo; }
public function set foo(value:Boolean):void { _foo = value; }
are masturbating and I'm not impressed by their bloated ego...I mean code. ;)
Unless something needs to happen immediately within the class when you set or
get a prop (i.e. a state change), it's fine for it to be a public var. It's
faster, it's less bloat and most of us aren't writing large applications with a
bunch of other developers. Some of these rules were created for when good
coders are forced to work with bad coders and the good ones need to protect
their code from the bad ones. When it's just you and a couple other devs, and
you're all competent, you don't need all these checks and balances that are
nothing more than compensation for people who you wish you didn't have to code
with. /rant ;)
On the FlashDevelop tip:
http://www.stevensacks.net/2008/02/21/flashdevelop-code-generation/
http://www.stevensacks.net/2008/04/30/flashdevelop-flexbuilder-style-error-reporting-on-save/
FlashDevelop's auto-completion and code generation are better than anything out
there (for AS, at least). And just to be clear, you don't need to select
anything for code generation, the cursor just needs to be anywhere within the
word, or at the end of the statement.
private var _test:Boolean;
If the cursor is after the semicolon, you can press the shortcut (I use ALT+2 on
Windows, CMD+2 on OSX) and it will bring up the code generation options. The
event generation is really valuable, as well. I save so much time with it.

Re: [Flashcoders] frameworks and flash
Joel, Considering the types of Flash sites you're talking about building, Flex is not the solution you need. However, Flex is absolutely worth learning, if only to expand your skillset which leads to making more money per hour. ;) Out of all the frameworks you listed, only Gaia is for making the types of websites you said you are making. The rest are application frameworks. PureMVC, Mate and Cairngorm are primarily intended to work with Flex and any support you seek on learning those frameworks will most likely come from Flex developers and not Flash ones. They are important to learn if and when you learn Flex. Gaia AS3 is only 40k (AS2 is slightly smaller). I hate code bloat and have spent a lot of effort keeping Gaia as lean as possible. There's even an option to optimize the main.swf by removing any assets you aren't using in your site, which can potentially decrease the file size down to 29k. A lot of developers and designers making the transition from AS2 to AS3 have found Gaia very helpful in that process, since it takes care of a lot of the extra code that is so overwhelming, and gives you time to slowly acclimate to the changes. Gaia also has an active forum with over 800 members, a robust Wiki and documentation, ASDocs, and I am available on the forums every day answering questions.

Re: [Flashcoders] AS3 - Checking if a Function Exists
There's a bug if you return in a try or catch (maybe it's just catch). Colin Moock mentions it in his AS3 book. I personally think it's cleaner to return after a try catch because try catch is not an if else and really shouldn't be treated as such, but that might be because I have avoided returning inside them since I first started using them because of the bug. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

[Flashcoders] AIR: Drag and Drop between NativeWindows
I'm trying to figure out how to do drag and drop between two NativeWindows. Not drag and drop between the OS and AIR, and not drag and drop in the same window, but between two NativeWindows of the same AIR application. I've tried all manner of guessing, and I can't find a single example on google of how to do this. From the stage.mouseX on the "drag to window" returning impossible numbers (like 65710) to Rectangle intersects not responding in reliable ways.

[Flashcoders] AIR WebKit browser breaks when internet is slow
If a web page is having latency problems, like YouTube during heavy load times (like now, 9:30pm PST), then AIR's HTMLLoader has all kinds of problems. From rendering stuff completely incorrectly, to failing to pass Flash player detection, to this crazy error that got spit out when I tried to load a YouTube URL in it and it hung for about 20 seconds until finally this junk was spit into the output window: ReferenceError: Can't find variable: initWatchQueue undefined at http://www.youtube.com/watch?v=RbdbVhBGETQ : 77 ReferenceError: Can't find variable: writeMoviePlayer undefined at http://www.youtube.com/watch?v=RbdbVhBGETQ : 375 undefined at http://www.youtube.com/watch?v=RbdbVhBGETQ : 375 ReferenceError: Can't find variable: delayLoad onload at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1646 ReferenceError: Can't find variable: delayLoad onload at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1585 ReferenceError: Can't find variable: delayLoad onload at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1524 ReferenceError: Can't find variable: delayLoad onload at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1545 ReferenceError: Can't find variable: delayLoad onload at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1667 ReferenceError: Can't find variable: delayLoad onload at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1565 ReferenceError: Can't find variable: delayLoad onload at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1687 ReferenceError: Can't find variable: delayLoad onload at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1626 ReferenceError: Can't find variable: delayLoad onload at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1606 TypeError: Undefined value undefined at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1 undefined at http://www.youtube.com/watch?v=RbdbVhBGETQ : 1 Debug session terminated. Note that none of these variables are mine. Also note that Firefox doesn't have the same latency that AIR is having. This is running in Flash CS3 IDE Debug Mode AIR publishing. Trivial code here, too. I'm literally just creating an HTMLLoader and telling it to load this YouTube URL. Any ideas? I'd like to point out that Firefox actually loads that same URL fairly quickly (maybe 5-7 seconds with latency) but AIR is significantly slower every time. Sometimes it succeeds at loading it and rendering the page correctly, sometimes it loads the page but the YouTube player is drawn above the stage about half its height, sometimes it crashes Flash when it hangs too long. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] AS2 Dispatch Custom Event of loaded clip
Wow. That's a crazy amount of code for something so simple.
Here's what I use:
---
import mx.events.EventDispatcher;
class net.stevensacks.utils.ObservableClip extends MovieClip
{
public var addEventListener:Function;
public var removeEventListener:Function;
private var dispatchEvent:Function;
function ObservableClip()
{
EventDispatcher.initialize(this);
}
}

Just have your MovieClip classes extend ObservableClip instead of MovieClip and
you can addEventListener and dispatchEvent simply and easily.

[Flashcoders] BUG: channel.position doesn't work with mp3s below 128kbps
Man I just keep finding more and more bugs with Sound. This one is actually really bad because it has no workaround, unlike the others. If you have an mp3 file that is less than 128kbps and you get its channel.position at a particular point in time and try to play from that position it jumps ahead in the file. The amount it jumps ahead is based on how far away it is from 128kbps (a 56kbps file will jump more than a 64kbps one). But wait, it gets worse. Even though it has jumped ahead in the track, the channel.position returns where it's supposed to be, not where it actually is!! That's right!! channel.position says it's at 5000ms but it's actually somewhere around 8000ms, etc. and so on. I'm updating the position in a TextField in an ENTER_FRAME listener. Wow. I mean, just, wow. 128kbps and up works just fine. Anything less and you've got a bug. I've discovered so many bugs in the Sound class in the last 12 hours, it's kind of disheartening. I'm losing faith in the Flash player team and in Adobe for letting this kind of stuff get through QA. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Update: Unfortunately, it looks like even if you set the pan all the way in one direction or the other, it doesn't actually work. You can still hear the sound coming out of the side that it is panned away from. So, I guess this bug is moot since pan doesn't actually work properly in the first place. Jeez.

[Flashcoders] Another Sound Bug - transform.pan
var snd:Sound = new Sound();
snd.load(new URLRequest("assets/sample.mp3"));
var ch:SoundChannel = snd.play();
var st:SoundTransform = ch.soundTransform;
st.pan = 1;
ch.soundTransform = st;
trace(st.pan);
trace(ch.soundTransform.pan);
st.pan = -1;
ch.soundTransform = st;
trace(st.pan);
trace(ch.soundTransform.pan);
Output:
1
1
-1.0004
-0.98809998
You can CLEARLY see me set the pan to 1 and then -1. But, if you notice, the -1
pan is a bit below -1 on the transform, but when you apply the transform to the
channel, it goes above -1.
I've got a sound mixer than I can set the volume on left and right individually
and I hear the sound on the right when it's at -0.988, but I cannot hear the
sound on the left when it's at 1.
How many more bugs are there in the Sound class?

Re: [Flashcoders] BUG: Channel.position returns out of range positions on looping Sounds
Modulus works, too, but that doesn't solve the issue that looping sounds return out of range values, nor does it fix the issue that channel doesn't have a proper pause() method like NetStream does. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
[Flashcoders] BUG: Channel.position returns out of range positions on looping Sounds
I don't know if this has been documented or not. I've never seen anyone report it. If you set a Sound to loop, it's channel.position property returns a number out of range of the Sound.length after it loops. The position property just keeps on incrementing beyond the length when you loop a sound. If you try to play a Sound from that out of range position, the Sound glitches out, because that position is invalid. Flash should not return a position to you that you cannot use. This all revolves around the fact that Sound has absolutely no way to pause right now. I don't know why Adobe did not give us a channel.pause() method, but they didn't. Because they didn't, this bug gets worse. The only way to pause and unpause a sound in Flash is to store the current position of the channel and call channel.stop, and when you unpause, you call sound.play(position). If the sound is looping, the position returned will eventually be higher than the length, which means the Sound glitches because you're passing an out of range position, a position, once again, that Flash returned to you as VALID. Wait, it gets worse. If you unpause a looping sound by passing its position, when it loops, it will loop from that position, not the beginning of the Sound. Do you see how this gets worse? There is no pause method, and without a pause method, there is no workaround for the above bug and issue except to manually loop a Sound by adding an event listener to the sound complete event (which can be unreliable), and calling play on it again and managing the looping manually, which undermines the loops argument of the Sound.play() method and requires a fair amount of code. We need a channel.pause(flag:Boolean) method. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] OT: Questions to ask an interviewee
There's a company here in LA that gives you a choice of tests and you can take them home and work on them. I heard what one of the tests was at 1:00am late one night and I was so psyched about it that I ended up staying up til 5:30am doing it. I wasn't happy with my first solution, which worked but wasn't as elegant as I liked, so I refactored it until I was satisfied. The particular test I took I thought was a fantastic way to figure out somebody's problem solving skills. I heard the next day that most applicants failed that particular test, including the guy who told me about it! (I can imagine it causing the Flash player to have script timeout errors). I mean, you have to come up with a good challenge worth doing. You'll also get an idea of how passionate people are about coding by giving them a challenge. I want to interview at that company just so I can find out what their other tests are and take em, ha! Here's what you have to decide. What are you trying to determine about somebody's skillset? Do you do a lot of collision detection stuff? Are you more interested in design pattern knowledge? Once you know what the goal is, you can come up with a test that will demonstrate their skills in that area. No, I'm not going to tell you what the test is. :) ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
