Re: [Flashcoders] constructor interpreted?
I think Kevin is referring to JIT (Just In Time) compilation. While it's true that actionscript source code is always compiled to platform-independent bytecode, this bytecode still has to be converted into native code before being run. That's what JIT (basically a compiler embedded into the virtual machine) does, at runtime. In some environments, such as .NET if I recall correctly, this happends upfront. The VM compiles the bytecode to native code, caches it and always runs the native code. In Java, this happens on demand, I think, but the VM detects code that is run often, so it caches a native version of it. Last I heard, the AVM JIT compiles and caches all the native code, except for code in the constructors (I don't know whether this is up to date, or why are constructors exceptions to what seems to be the general rule).

Re: [Flashcoders] Unique array AS3
PS:
I mentioned that a random sort was not the best approach.
Here's a better way to randomize an array:
public static function shuffle(array:Array):void {
var tmp:*;
var cur:int;
var top:int;
cur = top = array.length;
if(top) {
while(--top) {
cur = Math.floor(Math.random() * (top + 1));
tmp = array[cur];
array[cur] = array[top];
array[top] = tmp;
}
}
}

Re: [Flashcoders] Unique array AS3
Try this:
function uniqueRandomInt(min:Number, max:Number, n:Number) {
var a:Array = [];
var i:Number = min;
while (a.push(i++) 0)
as evenly distributed as possible. Math.random gives you a number that
is great or equal to 0 and *less* than 1. It will not give you 1 back
(0.9, but not 1).
So if you do:
Math.random() * 2
You'll either get 0 or 1 (with decimals); it's not posibble to get 2. You
should instead use 3 as the multiplier and floor it; the result should be 0,
1 or 2 (this will have as much randomness as Math.random provides). Now
substract 1 and you'll get -1, 0 or 1, which is what you want for your sort
function.

Re: [Flashcoders] Automagically create an interface from a given AS3 class?
This is usually called "extract interface". In some languages like Java, there are a number of tools that let you do this; Eclipse comes with this refactor, for instance. http://www.javalobby.org/java/forums/t19062.html I know this isn't the answer to your question because you obviously need it for Actiosncript code, but maybe knowing the common name can help you narrowing you search (for what is worth, I'm not aware of any tool that offers this feature for AS).

Re: [Flashcoders] RE: swf not compiling
You've got a point. I read (but I don't know this first hand) that CS4 uses the SDK compiler. Maybe it's a modified version to accomodate the IDE needs (compiling graphics and other assets that the SDK doesn't have to deal with: think moviclips with their timelines, animations, shapes, etc). Probably it uses mxmlc as a backend to compile Actionscript to bytecode or something like that. At the same time, I think it's fair to reckon that the IDE generally has more stuff to compile than FB in the typical project (again, graphical assets, encoding audio, etc). Too bad what you mention about the IDE team; I'm tempted to say that it shows, though.

Re: [Flashcoders] RE: swf not compiling
I know this doesn't add any value to the problem discussed here, but if you don't mind this little rant, I'd like to point out that the Flash IDE has gotten worse with every major release (to me at least). And I haven't tried CS5 yet. Seriously, the last usable one was probably Flash 8. Thank godness, I use the IDE very sparingly and somehow got used to the asinine way CS3 handles panels; CS4 impressed me as even worse in this and other UI aspects, and much slower (it kind of makes Eclipse look slick, which is quite an accomplishment) so I try to avoid it as much as I can. I know my opinion is a bit biased since I don't take advantage of the new features they've added for designers (I only do some minor tweaks to fla's, just enough to make it possible to control assets from code). Nevertheless, it's horrendously clunky and slow (just opening the code panel to put a stop() or something takes seconds the first time). However, CS4 uses the Flex SDK Java compiler and I'm sure CS5 does too, so I guess it's probably not a compiler issue, just that the IDE is buggy and unstable. Given its evolution and the quality of the last few major versions, I'm not surprised, sadly.

Re: [Flashcoders] stop caching
If you are loading the swf directly from the file system (that is, localy)
appending parameters to the querystring won't work because they'll be
considered part of the file name. So those parameters will not be
interpreted as such. In a http environment (i.e. a server, local or remote),
on the other hand, the querystring will not be considered part of the file
name.
So yes, it's a local / server issue.

Re: [Flashcoders] Normalising Numbers
I think you're complicating the problem by introducing Math.abs which, I was
once told by a mathematically inclined colleague, is an arithmetic atrocity
(I've taken note of that since then and the nice thing is that almost
always, signs just work they way out without any extra help).
The formula is simpler than you probably think. You just need to find the
"size" of the range, that is the difference between the max and the min
values. Forget about signs, just take the max value and substract the min.
Easy as that.
If you have, say 10 and -4, the range "size" will be 14:
10 - (-4)
-->
10 + 4 = 14
The signs don't matter, as long as you always substract the smaller value
from the bigger one.
Now, once you have this value, you just have to find how far the ranged
value is from min and then "scale" it.
Let's say your value is 3. I picked 3 because it's easy to see it's in the
middle and that the result should be 0.5.
So:
"rangeSize" is 14 (max - min).
"min" is -4
"rangedValue" is 3:
How far is rangedValue from min?
rangedValue - min
That is:
3 - (-4)
or
3 + 4 = 7
Now, the last step, "scaling" it:
(rangedValue - min) / rangeSize
Replacing the values:
(3 - (-4) ) / 14
(3 + 4) / 14
7 / 14 = 0.5
And there you have it.
So a function to normalize a ranged value could look like this:
function rangedToNormal(ranged:Number,min:Number,max:Number):Number {
var rangeSize:Number = max - min;
return (ranged - min) / rangeSize;
}
Going the other way is simple too:
function normalToRanged(normal:Number,min:Number,max:Number):Number {
var rangeSize:Number = max - min;
return min + normal * rangeSize;
}
(Though above you might want to validate that the normal value is actually
normalized before converting it to the passed range)
Also, I'm not sure how you are calculating the min and max values of your
list, but if there aren't other specific requirements, you could just use
Math.max and Math.min. They accept a variable number of arguments, not just
two, so Function::apply comes handy here:
var min:Number = Math.min.apply(null,list);
This will give you the min value of the list with just one line, no loops,
etc.
So, to wrap it up, you could write your function in just a few lines, like
this:
function normalizeNumbers(list:Array):Array {
var min:Number = Math.min.apply(null,list);
var max:Number = Math.max.apply(null,list);
var len:int = list.length;
var result:Array = [];
for(var i:int = 0; i < len; i++) {
result[i] = rangedToNormal(list[i],min,max);
}
return result;
}

Re: [Flashcoders] Advice on calling subscriber script on another server
I think the easiest option would be creating some sort of proxy in php, if
that's what's available to you on your server.
The only potential problem is (your) server configuration. Sometimes,
external connections are not allowed, so calling functions like
file_get_contents() with an external url won't work.
Also, it seems you need to POST your data, so it's a bit more complex but
not too much.
A week ago or so I had a similar scenario. Though there was a crossdomain
allowing connections from the production server, there was no crossdomain
policy for the staging and dev environments. I also had to receive and send
cookies, so I googled a bit and found this class, which was easy to use and
worked nicely for me
http://scripts.incutio.com/httpclient/
Some sample code for a POST request (taken from the project I worked on,
just slightly modified) :
$client = new HttpClient("theotherserver.com");
// this will print out useful info, enable it when debugging!
// $client->setDebug(true);
$client->post("/theservice.ashx", array(
'first_var'=> 'foo',
'second_var'=> 'bar',
'etc' => 'blah',
));
// check status code here...
if($client->getStatus() == 200) {
// a string with the server's response
$response_raw_data = $client->getContent();
}
Maybe you can give this a try, it's very simple to install and use (just
download and include the php file; you can find more code examples in the
site).
Again, in some configurations this code could not work; if any external
connection in your server is rejected, then there's not much you can do. But
even in the worst case, maybe you could find a third server that you have
control over and that allows you to open external connections, so you could
add a crossdomain there and run the php http client over there. Then,
instead of talking directly to the ad server or a local php script, you'd
call a third server that you control, which will proxy the communication
between flash and the ad server.
Hope it makes sense!

Re: [Flashcoders] Set HTTP cookies with navigateToURL()
If you have access to Javascript, you can set the cookies like this.
ExternalInterface.call("function() { document.cookie = 'foo=bar;
expires=Mon, 15 Nov 2010 23:59:59 UTC; path=/'; }()");
navigateToURL(new URLRequest("somepage.php"));
Then in somepage, your data will be available in $_COOKIE;

Re: [Flashcoders] Calling a Static Function
I see a couple of weird things in your code.
First, I think your code, as is, should give you a compile error. At least,
I get an error, with this code (which looks equivalent):
var mathClass:Class = Math;
//mathClass.random(); --> compile error
It works if I workaround the compiler check, though:
var mathClass:Class = Math;
mathClass["random"]();
So, it's weird that you don't get an error. Which leads me to believe that
perhaps, you have a valid reference to the AssetLibrary class in your
project. Have you double checked that?
Anyway, I'd change the name of the variable since it could be ambiguous (if
you happen to have a reference to the class). I mean something like this:
var AssetLibraryDef:Class;
AssetLibraryDef=
pEvent.target.applicationDomain.getDefinition("AssetLibrary") as Class;
try
{
AssetLibraryDef.initAssets(); //<--the error is here
}
Also, could it be possible that the compiled class in the loaded swf defines
the method initAssets as taking one parameter? Maybe there's some versioning
problem going on...
At any rate, you could use describeType on the Class object to inspect it.
This will list static methods and will tell you how many parameters they
define (and also the types).
In my example, it's simply:
trace(describeType(mathClass));
So, you could probably see this info doing:
trace(describeType(AssetLibraryDef));
Not sure where the problem could be, really, but perhaps this gives you some
idea.
Cheers

Re: [Flashcoders] Inheritance and abstract classes
Jason, I'm glad you liked it.
Yes, that's precisely the idea. Passing (or actually accepting) an interface
instead of a concrete class.
Following this principle, you could for example use some third party library
for collision detection instead of writting your own if you find one that
fulfills your requirements. This is a good example of when interfaces make
most sense (3rd party libraries). Suppose the author of this engine typed
the input param as some concrete class. It could be then complicated to
integrate with your game objects, because you'd have a hard requirement of
extending a given class, but your object probably already extends something
else. However, if it's an interface, it could be relativeley simple to
integrate, as long as you implement the methods that the interface declares.
And you are free to model your objects hierarchy as you see fit.

As long the language is static typed (or is dynamically typed but types contranis are enforced at compile-time, as in AS 2.0 and in some cases AS 3.0), the compiler checks that without the need of an interface. I'd say that, conceptually, an interface is every method and property (and event, arguably) that a type exposes. So, you know x, y, height, widht, etc, are part of DisplayObject's interface (even though DisplayObject is a class; one you cannot instantiate or derive from without crashing at runtime, though; but that's more a hack hardcoded in the player for the lack of support of abstract classes in the language; and if you ask me, DisplayObject should have been an interface or there should be an IDisplayObject interface, but I digress). Now, knowing an object has certain capabilities is very useful, especially when writting libraries, frameworks and that sort of code. Your code could declare that it accepts objects that comply with certain "interface" (and here I don't mean necessarily the interface keyword / construct, but rather what I said in the previous paragraph). This is what you pointed out. But the difference is that you can have an object implement an interface without coupling it with some concrete class. So it's more flexible and it's possible for some object to implement more than one interface (and possibly unrelated interfaces). In a game, for instance, you can have "entities" (or whatever you like to call it). Following you IMoveable example, you could have other interfaces such as IShooter, IHitable, etc. You can have an engine that checks collisions and accepts IHitable objects; another engine would be in charge of moving the objects around and so it takes IMoveable object; another could be in charge of common tasks that need to be performed on shooters, so I'd act on IShooter's; and so on. Now, the advantage of using interfaces is that you can combine these sets of functionalities (as declared by the interfaces) in one object indepently, without having to force inheritance relations that might not make sense and could add nasty side-effects. I.e. an object could be hitable but not moveable, a shooter could be either moveable / not moveable, etc. So you could have a turret (IHitable, IShooter, but not IMoveable), and wall / obstacle (IHitable but not IMovable nor IShooter), and enemy ship (IHitable, IShooter and IMoveable), a bullet (IMoveable and IHitable but not IShooter since it doesn't shoot by itself). Without interfaces and only realying on inheritance this could turn into a mess rather quickly. This is important in languages such as Actionscript (which took the idea from Java), because multiple inheritance is not allowed. In other languages such as C++, you can have a class inherit from (and hence "being-a") any number of classes so the interface construct / syntax is not necessary (although multiple inheritance has other drawbacks and is more complex, and that's why it was left out of Java and other languages followed it this idea). That said, you don't need to have interfaces or even abstract classes for everything, in my opinion. This adds flexibility and some space for future expansion but it comes at the cost of making things more complex. If you're writing a library and want to allow different "clients" to use it, having your methods accept interfaces instead of concrete / abstract classes is a good idea. You can even provide some default / minimal implementation but leave it open to your "clients" to implement their own and still be able to use your library, without having to extend some class (which is not always possible / practical). In lots of application code, though, I think you don't really need this extra flexibility and many times it adds more work for little benefit.

Re: [Flashcoders] Using an embedded font
PS: If nothing else works and you're in a hurry, maybe this is worth a try. Make a new fla. Place a textfield on the stage and embed the fonts manually in the Flash IDE. Put this text field inside a MovieClip and export it. Publish this fla as a swc, add it to your FB project and somewhere do this to force the compiler to include this mc in your FB swf. var dummy:MyMovieClip; This should force the compiler to include the mc and indirectly the glyphs you have embbeded in your on stage text field. This is rather gross and unelegant and I'm not sure if it'll play nice with text fields created with code, but I generally work with fla's that have text fields with embedded fonts in the Flase IDE and having a dummy textfield is sometimes the easier way to make sure font are embbeded for the whole swf and that all text fields display the fonts correctly. 2010/9/22 Juan Pablo Califano > I hear you.

I hear you. The way flash handles fonts is a royal mess.

Re: [Flashcoders] Using an embedded font
Have you tried not setting the font name in the text format object? I think
it defaults to Times or something like that.
Then, if the text shows up, maybe the problem is in the font identifier.
You could then / also try this, which should give you the right name for the
font.
var font:Garamond3Embedded = new Garamond3Embedded();
textFormat.font = font.fontName;

Re: [Flashcoders] flv on fb servers not loading in ie only
Very weird. As you have noticed, it seems facebook is not serving the file under some circumstances (it returns a 404 http error code) I could make it fail consistently if: 1) The referer is set and is in a "non facebook" domain AND 2) The user agent is IE. I got the request to work if I set the referer to http://www.facebook.com/and leaving the user-agent as IE, for instance. It also worked, if I kept the original referer but used the same user-agent as Chrome: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/534.3 (KHTML, like Gecko) Chrome/6.0.472.62 Safari/534.3 I'm not sure if there's any work around from Actionscript, I'm afraid, as you have very limited control over the request headers sent to the server. I'm pretty sure you just can't change the user-agent or the referer. The only alternative I can think of is proxying your request through some server you control. But that of course negates the benefits of using facebook's CDN infrastructure and for your server traffic and load it would be worse that just hosting the video yourself in the first place. I'm sorry this isn't of much help, but I can think of any other work around. Let us know if you find something else.

Re: [Flashcoders] flv on fb servers not loading in ie only
I've had experienced problems with Facebook Connect on IE only. In my case, the user wouldn't even be able to log in, so I'm not sure this is the same problem you're experiencing. But anyway, maybe it's worth checking this: http://wiki.github.com/facebook/connect-js/custom-channel-url <http://wiki.github.com/facebook/connect-js/custom-channel-url>Basically, I set explicitly the channelUrl on initialization, like in the example and put the channel.html file at the same level that the xd_receiver.html file that is used for working around JS cross-domain issues. And it solved the problem. If I recall correctly, this custom channel url workaround is necessary only if your app isn't loaded within FB, as opposed to an external site that just uses Facebook Connect. (Or was it the other way around?) Hope this helps.

Re: [Flashcoders] parsing multi-dimensional array
It seems like you want to group your data by color and each of your items
consists of a string and two numbers.
Let's assume this items are points (holding an x and y value) that have a
label. (By the way, defining the data makes finding a good structure for it
easier; when you ask a question like this, some background on what your data
represents and what you are trying to do it is helpful).
Assuming this, I'd have an object or dictionary that groups lists of points
by color. So this object or dict would have one entry for each color. This
entry would be an array, that will hold points of a given color.
You could use a class or VO (as Jason suggested) to store each point. You
could also use an Object for this. Using an array is a bad choice if I
understood your problem correctly. Because you're saying "the label is the
first element, x the second and y the third; but it's much easier to give
each of this properties names, so it's more readable and less error prone)
In code, you could try something like this:
public class LabeledPoint {
public var x:int;
public var y:int;
public var label:String;
public function LabeledPoint(label:String = "", x:int = 0, y:int = 0) {
this.label = label;
this.x = x;
this.y = y;
}
override public function toString():String {
return "[LabeledPoint " + label + ", " + x + ", " + y;
}
}
public class PointsDictionary {
private var _dict:Object;
public function PoinstDictionary() {
_dict = {};
}
public function getGroup(label:String):Array {
if(!_dict[label]) {
_dict[label] = [];
}
return _dict[label];
}
public function addPoint(p:LabeledPoint):void {
var group:Array = getGroup(p.label);
group.push(p);
}
}
// use
var points:PointsDictionary = new PointsDictionary();
points.addPoint(new LabeledPoint("red",0,0));
points.addPoint(new LabeledPoint("red",1,0));
points.addPoint(new LabeledPoint("red",2,0));
points.addPoint(new LabeledPoint("blue",0,0));
points.addPoint(new LabeledPoint("blue",1,0));
points.addPoint(new LabeledPoint("blue",2,0));
// get the red points:
var redPoints:Array = points.getGroup("red");
// get the first red point:
var firstRed:LabeledPoint = redPoints[0];
Of course there are many other ways to do this, depending on your
requirements. The above is rather "raw" in that it gives you direct access
to the underlying storage (the arrays) and it's up to you to manipulate them
externally (I just added an addPoint method as a convenience to make the
code less verbose). You might want to prevent duplicates, be able to add an
item at a certain position, remove them, etc, etc. In that case, you could
consider adding other methods or (better) using some more specific data
structures, such as these:

Re: [Flashcoders] Error #2032
PS: Also, some RESTful services are rather strict about what HTTP command they accept. Some will only allow POST for some operations and GET for others. This might be the case here... As a side note, if you set your code to use POST but you don't send any data in the request body, flash will switch to GET silently (this is documented in "fine print" in the docs but I had missed). A simple solution for this is sending some dummy data to force flash to use POST. 2010/9/4 Juan Pablo Califano > It's hard to know what the problem is with such limited info. > > The first step to troubleshoot this would be inspecting the http traffic.

Re: [Flashcoders] Error #2032
It's hard to know what the problem is with such limited info. The first step to troubleshoot this would be inspecting the http traffic. I guess. The best tool for this that I know of is wireshark ( http://www.wireshark.org/). It's not the most friendly though and could be a bit daunting at first. Other option is Charles (http://www.charlesproxy.com/). Less powerful, but good enough for inspecting communication between your app and the rest of the world. Also, it's much more friendlier and intuitive. Install any of the above and run your app. Then check the server response to see if it rejected your request for some reason. Probably not the case here, but I once had a similiar problem (using POST or GET made no difference, though). Whenever I connected from the IDE, the server responded with some fault code (can't remember if it was 500, 403 or something like that). However, if I run the code from a browser, it worked (I was running from localhost and already had sorted out crossdomain issues). Now, the curious thing was that if I had charles running, it worked both from the IDE and the browser. So I suspected and confirmed later that the server app I was connecting to was inspecting the user-agent in the request header and explicitly rejecting flash for some dumb "security reasons" (when charles is running it proxies your http traffic and changes the user agent). Anyway, this was rare; most server side scripts / apps won't check the user agent (because this piece of data is sent by the client anyway, and no real security could be enforced just by inspecting it).

Re: [Flashcoders] Getting the url where my Flash movie was embeded
Maybe you could try a different approach. Although it's not 100% authoritative, the http referrer of the http request made to get your swf could help here. This is data sent by the client (the browser in this case), and might not even be sent to the server, but in almost every case, it is. So, you can check your server's log and filter out requests for your swf. In Apache, at least, the referrer will be logged by default. A little twist to the former could be serving your swf from a server side script. If you are using php, this is quite easy. Instead of giving your users a link to your swf, tell them to link to yourserver.com/your_widget.php. This php file will read and store the referrer and then just return the swf (a simple redirect to your swf will do it).

Re: [Flashcoders] Facebook API GetPhotos not working
It's most likely a permissions problem. Even if your pics are public, you (as a user) have to grant the app access to your data (except for the most basic stuff such as name, etc). This wasn't necessary before, if I recall correctly, but alas, FB API is rather unstable. They seem to change their minds about how things work all the time (and are not afraid of breaking the code of the suckers that use their services; you can get away with it if you're facebook, I guess). Check this out: http://code.google.com/p/facebook-actionscript-api/issues/detail?id=146 How do you ask the user for permssions? This doesn't have an easy answer, I'm afraid. It depends on how your app connects to FB. I've used the "official" AS library above in one project and I know it's actually a wrapper around a JS library. Don't remember the specifics, but I do remember that in all of the client libraries I used (the old JS client, the new JS client that uses the new Graph API and the PHP client), you can request a check for permissions when you call the login function; and if said permissions were not granted, the user will be presented a popup to accept or deny your app these permissions. So you have to look up what's the name of the permission (whatever they decided it to call it this week) and how you can pass that to the JS code that actually connects to FB (I think there was something for that already in the AS library, but I'm not positive). This should solve the problem in most scenarios, I think there are some cases not covered here, such as if the user is already logged in when they get to your app; the login method won't be called, so the user won't be asker for the necessary extended permissions; if they already grant your app these, no problem; if they don't or they revoked them, you'll have to work around this somehow. I remember I had to do this a while time ago (using the new JS client for the Graph API), but it was a mess, and involved using FQL from JS and whatnot... (all this because there's a very useful method in the FB API that returns the user status, but they forgot to include the current permissions granted by the user in the response; so you have to find other way to get that data, which in my case was using an ad hoc SQLish language called FQL. -- Sorry, this last paragraph was mostly a rant; developing against the FB API is a bit frustrating at times...) An alternative approach I used (but only because I had to use the new Graph API) was doing something similar to what this guy did: http://wellconsidered.posterous.com/fbflashbridge-v01 It's not as nice as the "official" library. It's kind of bare bones: some JS glue code around FB's JS client and a bit of Actionscript to communicates with it. You don't have all the typed objects and stuff. I must say, compared to adobe's lib, it was way easier to debug / troubleshoot, though (since there's way less code and it's kind of easy to follow it; anyway, I used this approach because I had to use the graph API, but if I had to do any other FB app, I think I'd go this way, but that's just me, I guess). Hope this helps somehow or at least gives you some pointers. Cheers Juan Pablo Califano 2010/8/10 David Hunter > > Hi List, . Anyone have any experience with the Facebook API?

Re: [Flashcoders] fileReference failing silently
The issue here is quite likely the garbage collector doing its job...
You FileRefence object is referenced only in a local variable in
the deskClickHandler method. After the method returns, since there's no
other reference to it, it's eligible for collection. So it might stick
around or not. In your case, it seems it doesn't. Try storing the fileref in
an instance variable instead. It should fix it, I think.

Re: [Flashcoders] const inside function
The difference is that the reference is constant, meaning you cannot change
it.
You can't do this:
const my_var:String = "my_var";
my_var = "other text";
You could do this if it were declared as a var.

Re: [Flashcoders] Question on variable init in a for loop
Agreed, that was over simplified.
I probably should have said clearly I was using "global" in a rather loose
way -- as opposed to function local; that's why I put the quotes. I just
wanted to point out what the problem was in the original question, in a
simple way, without getting into activation objects and other stuff.
Thanks for your clarifications.

Re: [Flashcoders] Question on variable init in a for loop
In actionscript you have only local and "global" scope. Meaning a variable
can be declared as local to the function or in the class that contains it.
Other languages allow for creating further scopes. In Java, C, C++, C#, for
instance, you can do something like this:
int i = 0;
{// this creates a new scope
int i = 8;
}
And you will get 2 different variables. Obviously, naming both the same is
not the smartest move, but it's legal (at least in C#, if I recall
correctly).
Also when you write a loop, the counter var will be local if declared in the
loop. I mean this:
for(int i = 0; i < 10; i++) {
// do something with i
}
//this is invalid, i doesn not exist here...
i = 20;
Now, in Actionscript this is not possible. You can declare a variable
wherever you like. The compiler ends up moving the variable to the top of
the scope when generating the bytecode (I think this is called hoisting).
So this:
var l:Array = [{},{}]
function test():void{
for each(var i:Object in l){
var id:String;// = null;
trace("1" ,id);
id = "test" + Math.random().toString();
trace("2" ,id);
}
}
Is equivalent to writting this:
var l:Array = [{},{}]
function test():void{
var id:String;// = null;
for each(var i:Object in l){
trace("1" ,id);
id = "test" + Math.random().toString();
trace("2" ,id);
}
}
"id" will be declared (and initialized to null) only once, before you access
it in your code. So you only have one variable, really and that's the reason
for the behavior you observed.

Re: [Flashcoders] using fscommand or externalInterface - no luck
Check the allowscriptaccess property in your embed code. By default it's
"samedomain", I think, so if your swf and your html are in the same domain,
it should work without changing anythig, but it's worth checking
For instance, if you are using SWFObject and want to allow access from other
domains, you could do something like this:
so.addParam("allowscriptaccess","always");

Re: [Flashcoders] SCORM Q - Strategies for saving large suspend data strings
I'm not sure you are really going to gain that much by using JSON instead of XML. ByteArrays have built-in compression as you mention (I think the compression algorithm zlib). Since XMLs generally have a fair amount of redundancy, it will probably reduce the size of your data (in bytes) considerably. To be safe, encode the bytearray to base 64 and store that. Base 64 means 1/3 overhead (for every 3 bytes in, you get 4 bytes out). Still, it'll probably be smaller than the equivalent JSON (though you might want to test it and see if this is true).

Re: [Flashcoders] Listeners (was no subject)
Maybe you didn't read what I worte carefully or maybe I didn't explain it
clearly enough. But note I made a distinction between the dispatcher - the
object that performs the callback, directly or through dispatchEvent - and
the code (let's refer to it as the "first caller") that calls the method
that contains the dispatcher.
Now, what I mean, and I repeat it now, is that if the dispatch is
synchronous or asynchronous changes the stack call: in the first case the
"first caller" will be on the stack; in the second, it won't.
Perhaps this code makes this easier to see (modified from the previously
posted code):
package {
import flash.display.Sprite;
import flash.events.Event;
public class Main extends Sprite {
public function Main():void {
runTest();
}
private function runTest():void {
var callbackTest:Tester = new Tester();
callbackTest.run(callback);
var eventTester:Tester = new Tester();
eventTester.addEventListener(Event.COMPLETE,handleComplete);
eventTester.run(null);
}
private function handleComplete(evt:Event):void {
trace("entering handler");
var stacktrace:String = new Error().getStackTrace();
trace(stacktrace);
trace("returning from handler");
}
private function callback(evt:Event):void {
trace("entering callback");
var stacktrace:String = new Error().getStackTrace();
trace(stacktrace);
trace("returning from callback");
}
}
}
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.utils.setTimeout;
class Tester extends EventDispatcher {
public function Tester() {
}
public function run(callback:Function):void {
setTimeout(function():void {
trace("entering run");
if(callback != null) {
callback(new Event(Event.COMPLETE));
} else {
dispatchEvent(new Event(Event.COMPLETE));
}
trace("returning from run");
trace("");
},1);
}
}
Just added a setTimeout to ensure it's asynchronous, but the same will
happen if you load external content, for instance.
As you can see, runTest() (the "first caller") is not in the call stack in
this case (while it was where the dispatch was synchronous):
entering run
entering callback
Error

Yes, the dispatcher and the listener are both in the same call stack always, but I think what we were discussing is whether the caller (the original caller, the one that calls the method that will eventually dispatch the event) is in the same callstack as the listener / event handler. That's not always the case, as it depends on whether the event is dispatched synchronously or not.

I agree with everything you say, up to that point. There is a
fundamental difference in the way callbacks and messages work. A
callback puts the caller on the call stack, and control will
eventually return to that calling method. A message does not put the
sender on the call stack.
>>>
Well, that's what happens in most cases, but as I said before, it's not
because of how event dispatching works, but rather because most events are
dispatched asynchronously (or most events dispatched by the player itself
anyway, such as those fired by loaders, mouse interaction, etc).
But, my point was that the event dispatching mechanism is not inherently
asynchronous. So an event handler could be called just like any other
callback.
To make my point more clear, consider this code and look the stacktraces it
prints out:
package {
import flash.display.Sprite;
import flash.events.Event;
public class Main extends Sprite {
public function Main():void {
runTest();
}
private function runTest():void {
var callbackTest:Tester = new Tester();
callbackTest.run(callback);
var eventTester:Tester = new Tester();
eventTester.addEventListener(Event.COMPLETE,handleComplete);
eventTester.run(null);
}
private function handleComplete(evt:Event):void {
trace("entering handler");
var stacktrace:String = new Error().getStackTrace();
trace(stacktrace);
trace("returning from handler");
}
private function callback(evt:Event):void {
trace("entering callback");
var stacktrace:String = new Error().getStackTrace();
trace(stacktrace);
trace("returning from callback");
}
}
}
import flash.events.Event;
import flash.events.EventDispatcher;
class Tester extends EventDispatcher {
public function Tester() {
}
public function run(callback:Function):void {
trace("entering run");
if(callback != null) {
callback(new Event(Event.COMPLETE));
} else {
dispatchEvent(new Event(Event.COMPLETE));
}
trace("returning from run");
trace("");
}
}
The results are:
entering run
entering callback
Error
at Main/callback()[Main.as:29]
at Tester/run()[Main.as:49]
at Main/runTest()[Main.as:13]
at Main()[Main.as:8]
returning from callback
returning from run
entering run
entering handler
Error
at Main/handleComplete()[Main.as:22]
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at Tester/run()[Main.as:51]
at Main/runTest()Main.as:17]
at Main()[Main.as:8]
returning from handler
returning from run
If you factor out the 2 native methods involving in calling the event
dispatching (which are there just because of the generic nature of
dispatching as opposed to having your callbacks hardcoded), the call stack
looks exactly the same both for the direct callback and the event case.

Re: [Flashcoders] Listeners (was no subject)
I agree on your point of custom events being cleaner and easier to follow. In a way, it's like using an Object and defining a class. You can get away with both, and both could be fine. Defining a custom class, although it's some more work upfront, pays off in most cases. Maybe I'm spoiled at this point, but just having the compiler type-checking and auto-completion makes a huge difference. A callback, on the other hand, offers a simpler interface, but it's less self-documenting (now, if you were able to use some kind of typedef's for functions -I think haxe has this feature-, it would be another thing). I tend to use callbacks especially for onliners or where I don't need much control from the caller (in cases where you just want to signal "this is done" or "this has failed", that sort of thing). I'm not sure I agree about callbacks potentially leading to hard-to-find bugs, though. At the end of the day, Events *are* callbacks. There isn't anything inherintly different in how they work. It's true that most events are dispatched asynchronously (those dispatched by most of the player's APIs), but Events per se are not asynchronous. I found out this the hard way, some time ago, when I had to spend a couple of hours tracking a rare bug in some app I was writting. It took me a while to realized that some function that dispatched an event was being re entered because of a not so obvious side-effect (when the caller received the message, under certain circumstances, it called some code that ended up calling code that ran this function; it was my fault and the code at that point was rather a mess, but I didn't consider the possibility of the function being re-entered because I -mistakenly- though that events were asynchronous; I think I wouldn't have had much problem diagnosing that bug if I were using callbacks in that case).

Re: [Flashcoders] display list overrides keyframes
A possible workaround could be adding a reset method that (re)initalizes the behaviour. You could move your constructor logic to this method. So, your constructor calls reset() when the object is first instantiated. Then, when neccesary, you could call this method to reset the behaviours (in a frame script in the timeline or where your code issues the gotoAndStop or gotoAndPlay that changes the frame). Hope this helps. Cheers Juan Pablo Califano 2010/6/21 Tony Fairfield > Is there a way to overcome the following: > > > > I have a timeline file, with quiz buttons on each frame.

Re: [Flashcoders] regExp
If don't want to learn the ascii codes by heart (or look them up), you can
use charCodeAt() like this:
var first:int = ("A").charCodeAt(0);
var last:int = ("Z").charCodeAt(0);
for (var i:int = first; i <= last; i++) {
trace(String.fromCharCode(i));

Re: [Flashcoders] Text area focus
Karl, I'm not sure how to benchmark memory in AS 2. I think that what you
might want to benchmark here is cpu performance, anyway.
In this particular case, I don't think you can benchmark much, though.
Basically, all performance benchmarks I've seen are based on getTimer (two
simple calls to getTimer, one before running the code you're interested in,
and one after; the difference is very roughly how much your code took to
run; there are more sophisticated suites (like Grant Skinner's), but to my
knowledge, all are based on the same principle).
The problem here is that what seems to be taking too long is an internal
mechanism of the player (managing and dispatching onChanged, for instance).
Can't think of a way of timing that off the top of my head.
If one the methods runs your fan wild and the other one doesn't, though, you
have a clear winner already!

Re: [Flashcoders] CameraDetection Update
Hi Ktu, I told you when you shared your code in this list I'd give you some feedback. I ended up using it a couple of months after that and totally forgot about telling you how it went, so sorry about that. But yes, it worked out great for Macs, which was the problem I was trying to solve. As I mentioned in my answer in SO, the code failed to get the correct camera for some laptops. I tried it in 2 machines, one was a Toshiba, the other one I can't remember for sure, but I think it was an HP. In both cases, it was Windows, one was running XP, the other one was running Vista, IIRC. The cameras were the ones that come built into the computer. I noticed I could detect those cameras fine the "regular way", and since I was in a rush, I just checked if the client was running Mac or not. If Mac, I used your code; if not, just went with the "regular way" (read, calling getCamera naively). I really didn't put much though to it; it just worked in the cases I tested and since the time frame was rather limiting, I left it that way. So that's why I mentioned some other possible cases were it could fail. Not that I found them, but I didn't test thoroughly either. Anyway, thanks for your class, it was very helpful (and I apologize again for not giving you proper feedback at the moment, as I said I would! But better late than never) Cheers Juan Pablo Califano 2010/6/16 Ktu > Hey List, > > Thanks to Ben and Juan I have made an update to my CameraDetection class. > > ChangeLog: > force settings dialog to open every time unless camera access is already > allowed > implement timer for checking permissions, sometimes the settings dialog > does > not dispatch > some logic updates > cleaner code (only 3 magic values) > > Check it out: link <http://blog.cataclysmicrewind.com/webcamdetection> > > Juan Pablo Califano! > I noticed today that it was your response to a question on > stackoverflow.comthat led Ben to my class.

Re: [Flashcoders] Text area focus
Not really. In theory, onChanged should be less intensive, I think. But,
from your description it seems it isn't, so go figure...
I'd go with the onSetFocus / onKillFocus then, but I'd do another test, just
out of curiosity. Instead of setting an enterframe when you get focus and
nulling it when focus is lost, what happens is you use the onChanged event
instead?
I mean, something like:
textbox.onSetFocus = function() {
textbox.onChanged = etc...;
};
textbox.onKillFocus = function() {
textbox.onChanged = null;
}

Re: [Flashcoders] Text area focus
It seems like you don't really need to bother about gaining or losing focus
here. Just listening to the change event will do the job and you could
remove the enter_frame.
commentxt_mc.onChanged = function(tf:TextField):Void {
var numChar:Number = 650 - tf.length;
if (numChar == 0) {
maxChar = "Max Characters Reached";
} else {
maxChar = "Max Char: " + numChar.toString(); //Have another
text box with the var maxChar to display the results while typing.
}
};
The equivalent in AS 3.0 is very similar, though a bit more verbose (as
usual!):
commentxt_mc.addEventListener(Event.CHANGE,handleTextChange);
function handleTextChange(e:Event):void {
var tf:TextField = e.target as TextField;
if(!tf) {
return;
}
var numChar:Number = 650 - tf.length;
var maxChar:String = "";
if (numChar == 0) {
maxChar = "Max Characters Reached";
} else {
maxChar = "Max Char: " + numChar.toString(); //Have another text box with
the var maxChar to display the results while typing.
}
}

Re: [Flashcoders] swf compressing
Are the swf themselves compressed? If not, you could give flasm a chance (http://www.nowrap.de/flasm.html). There's a switch that compresses the swf (-z). It's not the same as compressing the images separately, of course. But, if the swfs and the images are not compressed, the images should have at least some redundancy and compressing the whole swf might be of some help (though zlib is not going to be as good for compression as JPG or PNG). I'm just guessing, but maybe it's worth giving it a shot, since it's rather simple to try.

Re: [Flashcoders] Loading SWF file via Socket class / ByteArray
Yes, URLLoader will trigger a standard HTTP request. Meaning, you can see it with firebug, charles, etc. It's also possible to sniff a socket connection, but it requires Wireshark or similar software. Not sure if you gain much by using sockets, really, but anyway I'd just add that setting up the proper security context for sockets is a bit more involved (you have to run a service to serve a policy file from some port below 1024, etc), but it's feasible if you have control over the server.

Re: [Flashcoders] Loading SWF file via Socket class / ByteArray
You don't need to use a socket for this. Load the data with a URLLoader, setting URLLoader.dataFormat to URLLoaderDataFormat.BINARY. You'll get a ByteArray. Pass that to Loader::loadBytes() wait for the complete event to fire and you're all set. Well, almost. If the loaded swf is in a different domain, you need a crossdomain. If I recall correctly, this case also involved some LoaderContext particular setup (can't remember the details, though). You don't need to do anything server-side if you are serving the swf as a normal file.

Re: [Flashcoders] problem with strongly typed actionscript
Simple and gloriously concise example (as opposed to mine!). Here, whether the classes are native, or whether they are concrete instead of interfaces won't change the need for a cast; all the involved objects have commonalities but also important differences, and you want to treat them differently. Refactoring (if it were possible) to support "proper" polymorphism would obviously a bad idea, at least for me.

Re: [Flashcoders] problem with strongly typed actionscript
traffic; this site's traffic is huge, and though there are load balanced dedicated servers running it, completely purging the cache is something the stresses the whole infrasctructure, so the IT guys are rather reluctant to "full deploys". Now, the thing is (and I learnt this the hard way; thankfully this problem got caught in QA), interfaces work like classes in that if two swf use the same interface, the first one loaded is the one used (if they're loaded in the same app domain; loading it in a different domain kind of defeats the purpose of using such interfaces in the first place, though). But they don't work like classes in that they are verified by the player, at load time. If you change anything in a interface, and a.swf references the newer version while b.swf references the older one, the player will throw a VerifierError. I'm not sure you can even catch that, but even if you could, b.swf is dead code by that time; worse than that, it will take with it the rest of the code in every other swf loaded at that point. Basically, everything is broken; the only thing you can do is reload, but when you get to that point again, it will naturally blow, again. I kid you not: any change you make to an interface can cause this. Even adding an optional parameter to one method. This can be worked around, so I concede it's not impossible to rearchitech things. However, even for "full deploys", you have to plan ahead (picking the right time, coordinating with different teams, etc; and there's a time span of a few hours in which, by how the load balanced CDN work, you can't guarantee that a user will get the same version of all swfs; so basically, the site is half broken for that period). Again, I know this is not the most common case, but binary compatibility could be a problem in some situations and from my experience I've learnt that, sometimes, a minor "hack" is a lesser evil.

Re: [Flashcoders] problem with strongly typed actionscript
I agree with you, but I'add for the sake of completeness that, sometimes, relaxing the rules a bit becomes a necessary evil, like for instance, when doing a cast. When you do this: // bar is typed as ISomeInterface somewhere else var foo:SomeConcreteClass = bar as SomeConcreteClass; // or SomeConcreteClass(bar) foo.methodOnlyPresentInConcreteClass(); You are basically bypassing the rules of type system. You're telling the compiler that an object declared as ISomeInterface at compile time will be an instance of SomeConcreteClass at runtime. You're asking the compiler to trust you and not blow up when compiling your code. Some times this is avoidable with some refactoring (and or a better design). Sometimes it's not possible or impractical (this also depends on how purist you are, I guess). Nevertheless, having too many casts is usually considered a code smell for this very reason.

Re: [Flashcoders] External Interface with looped parameters
Whenever you need to pass a variable number of arguments, check
Function.apply().It generally will be the answer to your problem!
If I understood your problem correctly, this should do what you want:
var args:Array = [0,1,2,3,4,5];
var jsFunctionName:String = "someJsFunction";
var parameters:Array = args && args.length > 0
? [jsFunctionName].concat(args)
: [jsFunctionName];
ExternalInterface.call.apply(null,parameters);
Since ExternalInterace::call is static, the first param (the "this" context
object) is null.
The parameters are passed to the function as if you had written them in
source code like func(param1,param2,param3), etc, as opposed to
func(paramsArray).
Now, this works because ExternalInterface::call expects the first param to
be the name of function to be called and a variable (and optional) list of
parameters. So, you just have to build an array that contains in its first
position the function name and after that the rest of the args you want to
pass. In this example, this is equivalent to this code:
ExternalInterface.call(jsFunctionName,0,1,2,3,4,5);

Re: [Flashcoders] Question about approximate vowel detection in AS3
Wow. That was really uncalled for. Anyway, if you can pre-generate samples for all vowels for all samples, I can't see why comparing them to the speech generated by the same system would be any harder than comparing it to a number of collected profiles. >>> You really just need to collect profiles to match against. Record people saying stuff and match the recordings with the live data.

Re: [Flashcoders] AIR - ByteArray to BitmapData
If you want to convert it back to pixels, I'd say go with the Loader
approach.
Other than that, you'd have to write a JPEG decoder (seems like a waste of
time, considering you can already use a Loader, which would also be faster,
probably).
Now, if you are only interested in getting the width and height, that data
is in the SOFO block (SOFO stands for start of frame 0).
SOFO is marked by this sequence of bytes:
0xFF 0xC0
So, basically, you can loop through your bytearray until you find this
sequence.
Then offset your current position as necessary and read the height and
width.
If you take a look at the JPEG encoder from as3CoreLib, you can see you have
to skip 5 bytes from the beggining of the SOFO marker to get the height (2
bytes) and the width (2 bytes).
http://code.google.com/p/as3corelib/source/browse/trunk/src/com/adobe/images/JPGEncoder.as
Now, I haven't read the JPEG spec, so I'm not sure if this is a fixed
offset. I'm assuming it is, but you'd better check it if you want to use
this code. I've tried it with a couple of JPEG's and it worked fine,
though.
Also, you might want to validate if what you've got is a JPEG (check the
first 2 bytes for 0xff, 0xd8); you might also want to check that you're not
reading out of the buffer bounds.
function readJPEGSize(data:ByteArray):void {
var len:int = 0;
var i:int = 0;
var offset:int = 0;
while(data.bytesAvailable > 1) {
// look for 0xffc0
if(data[i] == 0xFF && data[i + 1] == 0xC0) {
offset = i;
break;
}
i++;
}
/*
writeSOF0(image.width,image.height);
writeWord(0xFFC0); // marker
writeWord(17); // length, truecolor YUV JPG
writeByte(8);// precision
writeWord(height);
writeWord(width);
Skip 5 bytes:
2 SOFO marker
2 length
1 precision
*/
var h:int = 0;
var w:int = 0;
if(offset > 0) {
offset += 5;
data.position = offset;
h = data.readUnsignedShort();
w = data.readUnsignedShort();
trace(w,h);
}
}

Re: [Flashcoders] tint a movieclip
To apply in code the same transform you set at author time in the IDE: var colTransf:ColorTransform = mc.transform.colorTransform; colTransf.redMultiplier = -0.18; colTransf.greenMultiplier = -0.42; colTransf.blueMultiplier = 0.22; colTransf.alphaMultiplier = 0.26; mc.transform.colorTransform = colTransf; The left values in the panel are the multipliers (one for each channel). There's a difference: in code the values are expressed as normal value in the range 0-1 (whereas in the IDE it's represented as a percetage, 0 - 100). So the above code will have the same effect as setting the left values to -18%, -42%, 22% and 26%. If you want to change the values in the right of the panel through code, set the offsets instead (the properties redOffset, greenOffset, etc in the ColorTransform object). They are expressed in the same units both in code and the IDE. Cheers Juan Pablo Califano 2010/5/19 Mendelsohn, Michael > Hi list... > > This is probably a bitwise question, which is why I'm posting.

Re: [Flashcoders] Two computers talking using AS3 Socket on same network
With non-Air players, you can use a Socket to connect to a server. But you can't create a server itself; i.e. you can't write code to bind to a given port and listen for connections. So, in that scenario you cannot connect both swfs directly (you have to use a socket server). Appartently with Air you can have your app bind to a port and listen for connections, so you can have 2 swfs talk to each other without the need of an extra party. (I say apparently because I've just found out about the ServerSocket class following the link that Henrik posted). Cheers Juan Pablo Califano 2010/5/12 Eric E.

Re: [Flashcoders] Producing a random list with no repeats
If that happens, it's a bug in the player. From the docs: "Returns a pseudo-random number n, where 0 <= n < 1. " So, the biggest number random returns can approximate 1, but should never be 1. What I got wrong in my original answer was that multiplying by 2 and then rounding introduces a bias towards 1 (and then if you substract 1, the bias is towards 0). Think about it this way: You've got a number between 0 and 1.9 when you do Math.random * 2. That is, a number that can get very close to 2, but never be actually 2. If you round it you'll get: 0 for 0...0.49 1 for 0.5...1.49 2 for 1.5...19 The actual numbers might not be exact as I'm not sure what's the boundary for rounding up or down; I'm also considering only two decimals for simplicity. But anyway, the distribution is obviously not even. There's about a 0.25 chance of getting 0, the same chance of getting 2, but the double, 0.5, of getting 1. However, if you multiply by 3 and floor the result (or coerce it to int for that matter), you get rid of the bias: Math.random * 3 will give a number in the range 0...2.99 So, if you get rid of the decimal part, you have: 0 for 0...0.99 1 for 1...1.99 2 for 2...2.99 Which gives a result that's clearly more evenly distributed than the first approach. 2010/5/9 Steven Sacks > In the exception that Math.random() returns 1, in which case you would get > 2. > > I don't use Math.random(), though, I use the Parker-Miller PRNG. > > > > > On 5/9/2010 5:01 PM, Juan Pablo Califano wrote: > >> PS 2: I think the correct way to write the function that returns a number >> in >> the range -1 / 1 is: >> >> Math.floor(Math.random * 3) - 1 >> >> In this case, you could indeed use int() instead of a static Math method, >> so >> I guess I was wrong about your function needing a Math.round call. >> > ___ > Flashcoders mailing list > Flashcoders@chattyfig.figleaf.com > http://chattyfig.figleaf.com/mailman/listinfo/flashcoders > ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Producing a random list with no repeats
PS 2: I think the correct way to write the function that returns a number in
the range -1 / 1 is:
Math.floor(Math.random * 3) - 1
In this case, you could indeed use int() instead of a static Math method, so
I guess I was wrong about your function needing a Math.round call.

Re: [Flashcoders] Producing a random list with no repeats
Steven, sorry to contradict you, but although your code is simple and sort
of works, there a couple of problems with it.
First, the sorting function is wrong. A sorting function is supposed to
return -1,0 or 1. But it only returns -1 or 0.
The problem is you are coercing the result to int. You should use Math.round
instead.
int(Math.random() * 2) will return 1 or 0, never 2, because the biggest
value Math.random will return will be close to 1, but never will be 1. So,
if Math.random returns say, 0.9, after you multiply you get 1.8; since
you're using int(), decimals will just be discarded (instead of rounded) and
the result will be 1. There's no way you'll get 2, only 1 or 0. Then you
substract 1, so your sorting function will return either -1 or 0.
Second, you don't need to sort the whole list. It's much more work than it's
needed to shuffle the array. While the Fisher-Yates algorithm is linear, the
sort is not. That is, if you have 40 items, you know the Fisher-Yates will
"visit" each list slot only once. That's not the case with the sort method.
It grows exponentially. Well, maybe not exactly exponential, I'm not
possitive, but it's not linear anyway, as this code shows:
var list:Array = [];
var numItems:int = 40;
for(var i:int = 0; i < numItems; i++) {
list[i] = i;
}
var calls:int = 0;
function randomize(a:int, b:int):int
{
calls++;
return int(Math.random() * 2) - 1;
}
list.sort(randomize);
trace("calls:" + calls);
Change numItems and you'll see what I mean. Bottom line, you're doing more
work than you need: you're calling a function instead of doing your
comparison inline and you are calling Math.random more than it's actually
needed to sort the list.
Third, the sorting algorithm works under the assumption that given two
objects they allways sort the same: either the first one is less than, equal
or greater than the second. That doesn't hold true if your sorting function
returns a random result. And I think maybe that's why the number of calls
that the above code prints vary even when you have the same number of items.
Cheers
Juan Pablo Califano
PS. I also used the method you describe (for years) until I read about its
problems, so I thought maybe this is a good opportunity to pass this info
on. To be honest, though, I don't think it will be a problem
preformance-wise unless you have a rather big array.

Re: [Flashcoders] Producing a random list with no repeats
A simple way:
Put all the candidate numbers in a list (in this case, 1 to 40). Then pick
randomly from that array, one at the time, and make sure you remove that
number from the candidates list, so you can't have duplicates.
In code (untested):
function getRandomList():Array {
var min:Number = 1;
var max:Number = 40;
var numItems:Number = 10;
var candidates:Array = [];
// fill up the candidates list with the "eligible" numbers
for(var i:Number = min; i <= max; i++) {
candidates.push(i);
}
var list:Array = [];
var idx:Number = 0;
var selectedNumber:Number = 0;
for(i = 0; i < numItems; i++) {
// get a number from the candidates list, randomly. Add it to the
result and remove it from the candidates list (using splice)
idx = Math.floor(Math.random() * candidates.length);
selectedNumber = candidates.splice(idx,1)[0];
list.push(selectedNumber);
}
return list;
}

Re: [Flashcoders] ASDoc & third party libraries
I think the problem is that you have to list all the classes you want to
exclude. In other words, you want to exclude packages, as you said, but
there's no option to exclude a package, you have to list all the classes.
If that's the case, a possible solution -other than doing it manually- is
using some script to generate a list of these classes given a path, then
copy + paste that after the -exclude-classes option.
Listing files is not that hard in batch and since you're on windows, you
have that option available already:
DIR /S /B *.as > fileList.txt
The problem is you have now a list of full paths. Converting a path to a
class name is not rocket science in any decent scripting language, but batch
hasn't earn the crappy reputation it has for being... easy to work with.
This should be easy to accomplish in php, python, etc, if any of these
is available in your computer. Or, maybe, you can try to write a JSFL script
to do the job, though you'll have to run it from flash. Or maybe an air app
if you're so inclined (perhaps overkill, but you already know actionscript,
so maybe it's the fastest option)
Anyway, I think if you manage to automate the generation of the exclude
list, you will be able to run the asdoc task without much manual work.
Just a few ideas, hope it helps.

Re: [Flashcoders] Can u combine....
I linke your solution and though I usually prefer to reuse objects such as
loader, I'm not totally against creating a loader per request since in some
situations it can be handy. But let me tell you, you have a subtle bug in
your code.
You need to pin down your loader somehow, because otherwise, since it's
local to the function, it could be garbage collected. I was under the
impression that an active loader would not be collected. It's rare that this
happens, but it's possible. I've learned this the hard way, and it took a
while and some hair pulling to figure out where the problem was (I was using
a Loader object to load images, but the same principle applies to
URLLoaders).
This could be fixed by storing your loader in an instance-scoped array, and
then removing it (and its handlers) when the loader's job is done (either
because it succeded or failed), using the event.target reference to find the
loader in the array.
Cheers

Re: [Flashcoders] Security sandbox error during Upload/Download
Hi, >From the error message, it seems your swf is downloaded from mydomain.netbut tries to access www.mydomain.net. Crossdomains rules are subdomain based so you are not granted access to www.mydomain.net from mydomain.net. Most likely, you have the absolute url hardcoded somewhere, so when you access www.mydomain.net/my.swf it works, but if you change the url to mydomain.net (which problably maps to the same file as www.mydomain.net), it no longer works. The easiest solution probably is using relative urls. If for some reason that's not possible, anoher option could be placing a crossdomain.xml policy file that accepts both www.mydomain.net and mydomain.net. There might be other options (like forcing a redirect to one of the subdomains, passing a flashvar with the actual domain dynamically using some server side technology, etc) but I would just use relative urls, if possible, or a crossdomain file.

Re: [Flashcoders] Can u combine....
Another option:
function loadXML(dfile:String,arg1:Object,arg2:Array):void
{
urlLoader.load(new URLRequest(dfile));
urlLoader.addEventListener(Event.COMPLETE, function(e:Event):void {
parseXml(e,arg1,arg2);
});
}
function parseXML(e:Event,arg1:Object,arg2:Array):void
{
xmlFile:new XML(e.target.data);
totalBars = xmlFile.children().length();
}
This method has a drawback (and is usually frowned upon) because you cannot
remove the listener. In this case, though, I don't think this is a problem
(the loader seems to be owned by the class)

Re: [Flashcoders] How to remove bytes from the beginning of a ByteArray?
Hi, You've got the source / destination backwards. readBytes reads *from* the object on which the method is called. And it writes *to* the ByteArray you pass in the first parameter. So this: var newBA:ByteArray = new ByteArray(); newBA.readBytes(_ba); _ba = newBA; Is copying data *from* newBA *to* _ba. You want the opposite, so it should read: var newBA:ByteArray = new ByteArray(); _ba.readBytes(newBA); _ba = newBA; You can also do the read / write in place. It's a just bit more contrived but I'm not sure if it's worth it (it's less readable, I think). Here's how you'd do it, anyway: // let's assume for brevity that you've read 6 bytes from your original buffer and you still have data left (i.e., len > 6) var offset:int = 6; // how much to read? All of the remaining data, which is the current length, minus your current position (we said it was 6) var newLen:int = _ba.length - offset; // Read the data starting at current position and write it to the same buffer, starting to write at the first byte. // 0 is the offset in the *destination*. We want to copy the 6th byte into the 0th position, that's why we pass 0. // the third parameter tells the method how much to read from the *source* // for what you want you don't actually need to pass these two last parameters, since by default readBytes will write to *dest* at offset 0 // and will read from *source* all available data (i.e. from current position to length -1) _ba.readBytes(_ba,0,newLen); // you do need to set this since this read/wirte is in place and you want to shrink the buffer. Othewise, you'll end up with garbage after at the end of the byte array. _ba.length = newLen; And that's it. Hope it helps.

Re: [Flashcoders] XML question with a test case
Because your second query returns an empty list instead of null.
So, instead of checking for null, just check the length of the result.
trace(describeType(xml1.lobby)); trace(xml1.lobby.length()); // 1
trace(describeType(xml2.lobby)); trace(xml2.lobby.length()); // 0
The first time I noted this it also confused me. I think it's clearly a
feaure, though, and it actually makes sense to me, because, otherwise, you
couldn't safely write something like this:
trace(xml1.lobby.user);
trace(xml2.lobby.user);
If at some point your query returned null, you'd have to check for null
explicitly or wrap almost every single line of code that manipulates XML in
try/catch to make sure it doesn't blow up because of a null reference error.

Re: [Flashcoders] How to use Flex Builder's profiler???
Yes, taking a snapshot forces a GC cycle. You can also run it yourself at any time pressing the "Run Garbage Collector" button. Keep in mind that your disposing method will not cause your objects to be collected, but rather be collectable or eligible for GV. Until the GC kicks in, those objects could be unreacheable (if you managed to clean up properly) but still alive (and that's what the Live Objects view reflects).

Re: [Flashcoders] Crossdomain.xml, shared hosting, https, oh my!
I wouldn't worry about point 2). The only real reason for crossdomains (as I understand, at least) is solving this potential security hole: Let's suppose you're in a LAN that has access to some intranet; or to some servers that you have access to because you're in this LAN, but are not accessible from the internet, anyway. So, you can point your broswer to http://www.somesite.com (internet) and http://myprivate.intranet (LAN access only) and you will reach both. On the other hand, outside that LAN, you could only reach somesite.com but not myprivate.intranet. Since flash runs client side, if there were no crossdomain policy, the swf you downloaded from www.somesite.com would have access to myprivate.intranet. It could read data from it and send it back to www.somesite.com (or somewhere else). This opens a pontential security hole, especially for corporate intranets. To prevent this, a host must grant access explicitly. With the crossdomain files it states that it's ok for swfs downloaded from certain domains to communicate with it. So, the only potential problem here would be in your hosting provider's LAN, as I see it.

Re: [Flashcoders] Best MovieClip removal practice
For display objects, another option could be using the ADDED_TO_STAGE and REMOVED_FROM_STAGE events to initialize and destroy the object. In many cases, at least. In some others, especially if initialization is expensive, it could be better to have explicit methods for that. But I think in the general case, using those events simplifies the interface (meaning, the user of the class doesn't have to bother calling a destroy method, etc). Cheers Juan Pablo Califano -- Forwarded message -- From: Matt S. Date: 2010/1/6 Subject: Re: [Flashcoders] Best MovieClip removal practice To: Flash Coders List Not only is it better, but definitely best practice. The most basic method is to include a listener destroyer function within the class so that it can deactivate itself before being removed, eg: SomeMovieClip.destroyMe(); removeChild(SomeMovieClip); SomeMovieClip = null; there are fancier ways to handle this of course but thats the basic concept. http://www.almogdesign.net/blog/actionscript-3-event-listeners-tips-tricks/ .m On Wed, Jan 6, 2010 at 5:19 PM, ktt wrote: > Hello, > > After > > removeChild(SomeMovieClip); > SomeMovieClip = null; > > it will removed and will wait for garbage collector. > But maybe it is better to remove most unwanted listeners before nullifying the MovieClip and not wait for garbage collector? > It should save some memory space and time for actually "working" MovieClips and Events. > What do you think? > > Ktt > > > > ___ > Flashcoders mailing list > Flashcoders@chattyfig.figleaf.com > http://chattyfig.figleaf.com/mailman/listinfo/flashcoders > ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Best MovieClip removal practice
Running a GC cycle is rather intensive and can definitely have an impact on performance. It's a trade-off. You hold some memory for a little longer than you actually need, but you save on performance (and many times, memory is just sitting there with no one using it anyway... also, allocating and deallocatin has a cost too). Think about this. How do you know it's better to run a GC than holding back, say 50 Mb (in a computer that might have, say, 1 Gb to spare)? From actionscript, there's no way you can know when it's best. The GC has a better chance to make an educated guess, because it has access to some data that is not available to you.

Re: [Flashcoders] 64 bit integers
Maybe it's not exactly what you're looking for, but another option could be using a BitVector. You can find one in polygonal lab datastructures library, here: http://lab.polygonal.de/ds/ A nice thing about it is that you don't need to care about the number of bits you can use. Since the data is stored in an Array o ints, you can grow it as much as you need, while keeping memory use as low as possible (at least, in theory!). You can't check more than 1 bit at the time right now, but if you need to, perhaps you could tweak the class to accept masks... Some time ago I modified the BitVector class to use a ByteArray as its backing storage (but preserving the API).

Re: [Flashcoders] Caching loaded bitmaps
I don't know about Macs, but I have noticed this same caching behavior in the past using Windows XP and Flash CS3. If my memory serves me well, flushing IE's cache made Flash reload the images from disk (I discovered this by chance); this seemed a bit odd but I remember I could reproduce it every time. So maybe, and I'm just guessing here, this "feature" is due to how the Flash IDE works in Windows, and hence Windows only?

Re: [Flashcoders] Publish transparent .gif file in AS3
I'm not aware of any GIF encoders written in Actionscript. If you absolutely need to use GIF (and nobody has yet written an encoder in AS), I only see 3 options: 1) Get the GIF spec and write the encoder from scratch. 2) Find some open source encoder in other language (like Java) and port it to Actionscript. 3) As it was already suggested, use the PNGEncoder in as3corelib, send the encoded image to the server and have the server re-encode it to GIF. In php, using the GD library, re-encoding should be only a couple of lines. 1) is the hardest, and it's probably not worth the hassle. 2) is close to 1) in many ways. 3) is the most reasonable option, I think. Unless you absolutely need to do everything client side.

Re: [Flashcoders] regex issue when validating unicode range
Hi I don't think the regex is wrong. In fact, if you change u for a smaller number, it works fine. I have not tested each code point, mind you, but with a few tries, the highest max range that works that I could find is 0xFEFF. The range 0xFF00 - 0x apparently is reserved for control stuff. So 0xFEFF is the last value before that range. Not sure if the way the regex behaves is a bug or a feature, really, but you can probably get by with something like this: var testIsArabic:Boolean = /[\u0627-\ufeff]/.test(str.charAt(0)); Cheers Juan Pablo Califano 2009/10/19 Matt Muller > Hi there, > > issue with regex when trying to test if a char is within a unicode range > > var testIsArabic:Boolean = /\u0627/.test(str.charAt(0)); // this works > testing for arabic chars of unicode 0627 > > var testIsArabic:Boolean = /[\u0627-\u]/.test(str.charAt(0)); this > range does not work, returns false > > NOTE: the str.charAt(0) is 0627 > > any ideas? > > cheers, > > MaTT > ___ > Flashcoders mailing list > Flashcoders@chattyfig.figleaf.com > http://chattyfig.figleaf.com/mailman/listinfo/flashcoders > ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] [MEMORY LEAK]
I see. But when you refresh the page, the Flash Player instance is tore
down, so the player's memory is released. When you reload a stub swf, the
memory used by the player might or might not be released immediately. Most
likely it won't. That's not necessarily a bug or a leak. It could be, but my
point was that you should keep in mind that GC is not deterministic; because
maybe you don't have a leak in the first place. The mere fact that the
memory footprint grows doesn't mean there's a leak.

>>>
First and most important, are you sure it's leak? The fact that Firefox (not
even the player itself) doesn't release memory right away doesn't mean
there's a leak. At all.
Sorry for the self reference, but a while ago I answered a question in
stackoverflow about an alleged memory leak.
http://stackoverflow.com/questions/1020146/why-sytem-totalmemory-keeps-increasing/1022648#1022648.
Perhaps it helps to get my point across.
Looking at Qindows manager or System.totalMemory is probably the worst
possible way to detect a leak, given how the player works. You'll get tons
of false positives and the info is rather useless anyway.
What has been of great help, at least for me, is using Flex Builder's
profiler. It lets you inspect objects in memory, force a gc, etc. Plus, if
you do find a leak, you can trace where the leaked object has been
allocated. A simple test for your scenario would be taking a snapshot before
loading your swf, then another when it's loaded, then unload, force a GC and
take another snapshot. Then you can compare memory at those points and be in
a better position to determine if there's a leak, and, in that case, what
could be causing it.
Hope it helps.
