Re: [Flashcoders] URLStream, POST and requestHeaders

[EECOLOR]

I just found out the problem. If you put a value in the 'data' property of
the urlRequest everything starts to work:

*  var r:URLRequest = new URLRequest("http://www.google.com";);
  r.method = URLRequestMethod.POST;
  r.data = 0;

*

Now the request will be sent as post and request headers are sent with it.
Apparently the flash player thinks it is only usefull to check the
URLRequest for additional arguments if the 'data' property is filled.

[Flashcoders] URLStream, POST and requestHeaders

[EECOLOR]

Hello,

I am trying to do a request with custom request headers. In the
documentation I found the following line:

"Due to browser limitations, custom HTTP request headers are only supported
for POST requests, not for GET requests."

So I changed my request to post, the request however does not seem to go out
as a post request. The code I use to test is the following:

*  var r:URLRequest = new URLRequest("http://www.google.com";);
  r.method = URLRequestMethod.POST;

  var s:URLStream = new URLStream();
  s.load(r);
*

I have tested this both with Flash player 9,0,124,0 and 10,0,12,36
standalone.*
*

Is this expected behaviour and am I missing something, or should this work
just fine?

Re: [Flashcoders] addChild multiple instances of a loader

[EECOLOR]

If img.jpg is on the same server as your swf, you wont have a problem.
Otherwise you would need a crossdomain.xml.

>From the top of my head you could do something like this:

function onLoadComplete(e:Event):void
{
   var bitmap:Bitmap = Bitmap(_loader.content);

   var clone1:Bitmap = new Bitmap(bitmap.bitmapData);
   target1.addChild(clone1);

   var clone2:Bitmap = new Bitmap(bitmap.bitmapData);
   target2.addChild(clone2);
}

I am not sure if 2 Bitmap instances allow you to use the same bitmap
data. If that is not the case you could just copy the bitmap data.
This would however use more memory, so I would try the above thing
first.

Re: [Flashcoders] A Question that I've been asking for years!!

[EECOLOR]

There is one usecase that most Flash developers will come across. Lets say
we have a loader.swf in which the main (or base) class is Loader.as.
Loader.as loads main.swf, main.swf has as main (or base) class Main.as.
Loader.as needs to give a signal to the loaded main.swf and tries to type
the instance on the stage as Main. This way, Loader.as will makes sure the
file that is loaded is who he expects it to be (namely Main.as).
The above situation poses a problem. If Loader.as references Main.as,
Main.as will be compiled into loader.swf as well. In most cases this will
result in a loader.swf that is of the same size as main.swf. In order to fix
this we need to make use of an interface.
The Main.as will implement the interface and Loader.as will type Main.as not
as Main, but as the interface. This way only the interface will be compiled
into the loader and not the implementation (or Main.as). While this solves
the problem described earlier it also gives some extra benefits. The loader
is suddenly reusable. It no longer depends on a specific implementation of
any class. It will accept all classes that implement the interface.
I hope this usecase adds anything to the discussion.

Re: [Flashcoders] AMF objects storing in database

[EECOLOR]

In the example they expect you to implement IExternalizable. This is only
needed if you want to preserve properties that do not have both a getter and
a setter. In most cases a public var is enough, then you wont have to
implement the IExternalizable.

"I wanted to know, can I then just send the AMF object to a server and store
it as a binary in a mysql database? And also is this adviceable?"

I have used this approach to store typed and complex data that is only used
in Flash. I love it :)

Re: [Flashcoders] MouseEvents on overlapping siblings in AS3

Just a guess, but you could change the listener to MOUSE_OVER instead of
ROLL_OVER. The difference between the two is very subtle and explained at

applicable to the problem posed.

Re: [Flashcoders] delegate.create query

[EECOLOR]

The this within the xmlOnload now points to the object you gave as scope to
the create method of delegate.

In order to access the xml object you would need to reference xmlDoc
instead.

The whole point of Delegate is to make sure mehods are called with the
correct scope. xmlOnLoad will be called with the scope it's defined on as
you call Delegate.create(this, xmlOnload).

I hope this explains it.

Re: [Flashcoders] AS3 - A simple questions

[EECOLOR]

I would recommend using event.currentTarget instead of event.target at all
times.

the event.currentTarget property contains a reference to the instance at
which you registered the event listener. event.target refers to the class
that dispatches the event.

In this case there is no difference between .target and .currentTarget, but
in future cases you might encounter problems. The cases where you would use
event.target are so rare that I would urge everyone to allways use
event.currentTarget.

Re: [Flashcoders] API Interface in SWC...

[EECOLOR]

API's tend to be exposed through Interfaces. This allows you to program
agains an interface, keeping the implementation (concrete class) out of
sight.

You wrote:

*sumTwoNumbers(numA, numB)
{
   baseApp.sumTwoNumbers(numA,numB)
}*

You should make sure that baseApp is typed as an interface (for example
IBaseApp). Make sure that the BaseApp class implements IBaseApp. The
IBaseApp would look like this:

*public interface IBaseApp
{
   function sumTwoNumbers(numA:Number, numB:Number):Number;
}*

I hope this helps you.

Well, the thing here is that Math.floor is a function call. Function calls
are by default more complex than using operators. This would explain why
Math.floor is heavier than any other way of doing it.

You could create a bitmap using BitmapData.draw. Add that to your display

Re: [Flashcoders] Play MOV in flash

[EECOLOR]

If I recall correctly, you can only play .mov files if they are encoded with
the H.264 codec. And only if you have Flash player 9.0.124.

Re: [Flashcoders] Giving all objects new methods ...

[EECOLOR]

I created a file called dump.as within the fly.utils package:

*package fly.utils
{
   public function dump(obj:Object, maxSuperClasses_int:int = 0):void
   {
   };
};*

This way, I can just call* dump("something")*.

[Flashcoders] Why do you compile with the Flash IDE?

[EECOLOR]

I hardly ever use the Flash IDE these days. I program with FlexBuilder and
import images created by the designers. I am wondering, why are some of you
still using the Flash IDE to compile your applications?

What is the big benefit of using the Flash IDE in combination with
ActionScript?

Re: [Flashcoders] Data merging problem

[EECOLOR]

I am not sure why you have duplicate items. I am assuming these items come
from a database, you can use the query to leave out double records. In most
other cases, the double is in there for a reason, which means you do not
want to delete them. In that case you would like the .filterFunction
property. The filterFunction property is used to make sure an item is not
displayed while it is in the collection, this is used as follows:

*arrayCollection.filterFunction = removeDuplicate;

function removeDuplicate(item:Object):Boolean
{
   /*
  Do you magic here. More then one option exists. You could create
fingerprint of your object here and
  store it in an object as a key, like this:

  var ba:ByteArray = new ByteArray();
  ba.writeObject(item);

  var fingerprint:String = ba.toString();

  if (checkObject.hasOwnProperty(fingerprint))
  {
 keepItem = false;
  } else
  {
 checkObject[fingerprint] = true;
 keepItem = true;
  };

  The above method only works if you data does not contain an ID.
Another option (which might be faster
  in most cases, testing required) is to loop over the collection and
check if the items that contain the same
  data are infact the same objects. In this case I would not use a for
loop, but a while(i--) loop since these
  tend to be a bit faster and order does not matter in this case.
   */
};*

In order to apply the filter use the .refresh method of the array
collection.

Ahh, I re-read the the last question, hehe:

>is the only way to embed the font in the IDE??

Yes, you can not use AS3 to embed fonts if you are compiling using Flash
CS3. I am not sure what the problem is though. If you are compiling with
Flash CS3 anyway you have a way to embed them. If you insist on embedding
fonts using ActionsScript, you might consider downloading the Flex 3 SDK or
Flex Builder 3. The Flex SDK contains a compiler that can compile
ActionScript projects. You could use this compiler to compile your fonts
into separate swf and load those in.

>Flash doesn't understand any meta tags.

This is correct, Flash CS3 does not understand the metadata tags.

The ActionScript compiler from the Flex SDK does understand them, but not
all of them are usefull, most important, the [RemoteClass] and [Bindable]
tags can not be used in an ActionScript project.

The Flex compiler does understand them and also uses all of the Adobe
provided ones.

Make sure you have the TextField also set to the same size as the font you
embedded in the library. Also check if you maybe embedded the bold or italic

Re: [Flashcoders] The issue of "parent" in AS3

[EECOLOR]

I must disagree with this. Typing to Object will give you extra problems.
You will not get code hinting and are more likely to make typeo's. It also
is much more vulnerable to runtime errors.

As for the original message, I would encourage you not to call any
non-DisplayObject methods in the parent. This will tightly couple
the child to a specific parent, making it useless on other parents.

If you want to pass information to another object you can use the event
system and dispatch an event. Another options is to give the child a
property which is typed to an interface. This property should (in your case)
be set to reference the parent and will give you the ability to call that
specific method. On top of that, the child can be used with another
implementation of the logic you are trying to call.

If you are using Flex Builder to compile your ActionScript project, you can

There were some concrete answers posted to your question. Anyway, let's see
if we can solve it again.

Before I will try and help with your problem, I want to point out something
about your code. I am not sure if you are using (in your real application)
an interface which you will cast your class to:

*var _lm:ILoadMe = ILoadMe(_ldr.content);*

If you are using the actual class, the problem is that the whole class and
it's dependencies are compiled into you main swf, defeating a big part of
the purpose of loading the swf into it.

In my previous reply to your earlier email I posted a Flex version of the
answer. This time I created a Flash example. It is added as attachment.

The attached zip file contains 2 directories. Make sure you have your
webserver point to to these directories, the virtual hosts in apache:

*
  ServerName domain1
  DocumentRoot "E:\Projects\domain1"



  ServerName domain2
  DocumentRoot "E:\Projects\domain2"
*

In the hosts file (if you are on windows) you need these 2 entries:

*127.0.0.1 domain1
127.0.0.1 domain2*

In order to test the example, call this url: *http://domain1/domain1.html*

You should see this appear on your screen:

*domain1.swf
domain2.swf loaded
Domain2Base*

I hope this will solve your problem.

var ba:ByteArray = new ByteArray();
ba.writeObject(a);

ba2.writeUTFBytes(ba.toString());
ba2.position = 0;

trace(ba2.readObject() is Array);
ba2.position = 0;
trace(ba2.readObject());

Instead of ba.toString you could also use ba.readUTFBytes.

I think you could use a ByteArray to do it. It would be (from the top of my

t1BA.writeObject(t1Array);

trace(sBa.toString() == t1BA.toString());

Re: [Flashcoders] Is Adobe fixing this big FP9 problem?

[EECOLOR]

If I recall correctly, the problem only exists with event listeners for
Timer, stage and EnterFrame event listeners.

Stage listeners are easy to clean up. If you ever attach a listener to the
stage, add it within the ADDED_TO_STAGE handler, make sure you remove it
within the REMOTED_FROM_STAGE handler. I am not sure, but I think using a
weak listener here would do the trick as well and would prevent you from
needing to remove it.

As for Timer and EnterFrame events, make sure you never run them forever. In
all cases I can think of, there is no need to let them run forever. Running
them forever is just lazy programming. If you have a usecase where one of
these would run forever I am interested in it :)

As for normal events, this has (as far as I can tell) nothing to do
with problem mentioned by grant.

Re: [Flashcoders] Question about the AIR security model...

[EECOLOR]

Describe type is quite a heavy operation. I am not sure if it would affect
this application though. It indeed is an easy solution :) Another solution
would be to call the
loader.contentLoaderInfo.applicationDomain.hasDefinition(name:String):Boolean
method.

As far as the original problem is concerned, my thoughts about it:

When you load content from another domain (which is the case when loading
swf's in AIR from another location) they will automatically be loaded into a
child application domain. This means that both parent (the domain of the AIR
application) and child domain (the domain of the
swf) contain an definition of IAnimatedItem.

If you then check if the swf implements the parent definition it will return
false. The parent definition is not the same as the child definition.

>granted that the eventListener was added with a weak reference

This seems to be one of the biggest mis-understandings these days. The
listener does *not*add a reference to the object that you are
listening too. For extensive discussion and proof of this issue you
can read the following thread:


http://www.mail-archive.com/flashcoders@chattyfig.figleaf.com/msg38700.html

In short: adding a listener to an object will only create a reference from
the object to the listener, not the other way around. This means that you
can remove the object without removing the listener, the object will then
still be garbage collected.

In the above code I do not see why you would need any more then the

All references to basicNews are now removed and it is (along with its

Re: [Flashcoders] AS3 MouseEvent target?

[EECOLOR]

This behaviour can not emulated precisely because there is no way for us to
set the target and currentTarget properties. This is done by internal
EventDispatcher code.

The EventDispatcher code works something like this:

- check if the target property of the event has been set, if not set it
- set the currentTarget property
- check if the event has the bubbles property set to true
- check if the class is a DisplayObject
- check if the parent property is set
- clone the event and dispatch it at the parent and repeat the above steps

In my humble opinion I do not think this is what he needs. He should not be
referencing target, but instead he should reference currentTarget.

If you are adding a listener, the handlers e.currentTarget will point to the
object that you added the listener to, e.target is the object that initiated
the event (event bubbling).

So in a general way, where you in AS2 were using e.target you should now use
e.currentTarget. You only use
e.target if you want to reference the displayObject that initiated the event.

Re: [Flashcoders] Interfaces

[EECOLOR]

An interface is used to make sure your code is not tightly coupled. Instead
of saying which class should be given, you say which interface should be
given. This means that a developer has more freedom to implement his own
version of an interface.

Lets say you make a person interface called IPerson. This interface has name
getters and setters:

*public interface IPerson
{
   function get name():String;
   function set name(name:String):void;
};*

Now you want to fill up a classroom. The only thing needed within the
classroom is the name of a person. To add a person to the classroom you call
the addPerson method. The class:

*public class ClassRoom
{
   public function addPerson(person:IPerson):void
   {
//do stuff with the person
   };
};*

The addPerson method has a person argument typed as IPerson. This means that
I can give any type of instance to this function as long as it implements
the IPerson interface. This interface makes sure that the class given to the
addPerson method has a name getter and setter.

An example of a person:

*class Jack implements IPerson
{
   private var _name:String;

   public function get name():String
   {
   return _name;
   };

   public function set name(name:String):void
   {
  _name = name;
   };
};*

How my class implements the IPerson interface does not matter to the
ClassRoom class. The only thing the ClassRoom class is interested in is the
name getter and setter.

There are a few cases where interfaces come in handy:

- If you want to be able to easialy switch an implementation without
breaking existing code
- If you are using a module and want to call (from the module) a method in
your framework. The framework should be typed as an interface to prevent it
from being compiled into the module.
- If you are not taking care of the actual implementation (another developer
will write this piece of code), you only want a certain method to be
available because you are using this implementation.
- To give freedom to other developers of your code
(mx.core.UIComponentimplements IUIComponent in Flex. And within Flex
everything is typed as
IUIComponent. This means you could write your own version of IUIComponent if
needed.

On a side note. On complex applications I start with writing interfaces for
every part of my application to prevent me from writing actual code and
thinking about the structure. This approach has only personal benefits and
has officially no added value except for the ones named above (in a later
stage).

Re: [Flashcoders] Passing vars with the the timer and events

[EECOLOR]

I have modified my test classes slightly. And found that when debugging this
movie in Flex Builder 3, the garbage collection was triggered when I moved
my mouse within the Flash movie.

I suspect that the method behind the screens that runs the garbage collector
is quite complex. I think that in more complex applications garbage
collection is more efficient.


Counter.as

package
{
   import flash.display.BitmapData;

   public class Counter
   {
  public var bmd:BitmapData;

  public function Counter()
  {
 bmd = new BitmapData(500, 500);
 bmd.noise(Math.random() * 100);
  };
   };
};


SpriteClass.as

package
{
   import flash.display.Sprite;

   public class SpriteClass extends Sprite
   {
  public function SpriteClass()
  {
  };
   };
};


testAS.as

package
{
   import flash.display.Sprite;
   import flash.events.Event;
   import flash.text.TextField;

 var a:SpriteClass = new SpriteClass();
 a.addEventListener(Event.ENTER_FRAME, _handler);
  };

  private function _handler(e:Event):void
  {
 _t.text = _c.toString();

 _a.push(new Counter());

 _c++;

 if (_c > 300)
 {
(e.currentTarget as SpriteClass).removeEventListener(
Event.ENTER_FRAME, _handler);

Re: [Flashcoders] Passing vars with the the timer and events

[EECOLOR]

Hey there,

I was totally shocked this morning. If what you were saying was true it
would mean that if you created a class with a listener to itself and
instantiated it, it would never be garbage collected.

So I did some extra tests.

1. Your example with a weak listener (same result)
2. Trying to force garbage collection using System.gc and the
localconnection 'hack' (same result)

So I turned to the Flex Profiler. I used the following class to test things:

package
{
   import flash.display.Sprite;
   import flash.events.Event;
   import flash.system.System;
   import flash.text.TextField;

   [SWF(frameRate="1")]
   public class testAS extends Sprite
   {
  private var _t:TextField;
  private var _c:uint;
  private var _a:Array;

  public function testAS()
  {
 _a = new Array();

 _t = new TextField();
 addChild(_t);

 var a:SpriteClass = new SpriteClass();
 a.addEventListener(Event.ENTER_FRAME, _handler);
  };

  private function _handler(e:Event):void
  {
 _t.text = (_c++).toString();
 _a.push(new Counter());
  };
   };
};

Initialy the profiler showed the behaviour you were describing. However, if
I pressed
the "Run Garbage Collector" button, the instance of SpriteClass was
removed. This indicates the behaviour that I described in my example.

I changed the above example to use a weak listener. The instance of
SpriteClass was only removed after I clicked the "Run garbage
collector" button.

In the handler I removed the listener to the SpriteClass instance. The
instance of SpriteClass was only removed from memory after I clicked
the "Run garbage collector" button.

If I run the profiler with the
option "Generate object allocation stack traces", the instance is
removed everytime quite fast.


The conclusion of all this is that my statement in previous emails was
correct. What your example shows is that while the instance _can_ be garbage
collected, you will never know when it actually will.


A summary:

- There is no such thing as "a reference to be created invisibly within the
event system".
- You can not be sure when an instance is garbage collected.
- Weak references only indicate that: if the reference on the dispatcher
object to the listener is the last one, the instance containing the listener
will me available for garbage collection.


I want to thank you Cory for being as persistent as I can be. It enabled me
to do extensive tests to see
how the player works. In my tests in a standalone player there were
cases where I let the example application run for more then half an
hour without garbage collection of SpriteClass. I am not sure when the
garbage collector kicks in (might be triggered by total memory usage).
I will continue to monitor the
example
to see if the instance will ever be garbage collected. If not, I will
file a bug at adobe.

It is just a guess, but is the url in your swf "/video/pic_8.swf"? If so,
you might want to change it to "video/pic_8.swf" (without the slash at the

I think this is where we disagree. If a parent adds a listener to a child,
this means the child has a reference to the parent, not the other way
around. What you call the event system can be thought of as an array
with handler methods on the child instance. This means that if you add
a normal event listener to a child and then remove it, it will be
garbage collected. There is no such thing as "a
reference to be created invisibly within the event system".

>You can't use weak references on an anonymous event listener.

In my last email I agreed with you on this :)

>You must remove all normal listeners from an object before it will be
>garbage collected.

Again, I do not think this is correct. An object will be garbage collected
if there are no references to it. Adding listeners to an object will not
create references to the object itself.


An example (not usefull, but to illustrate the point):

package
{
   class TestClass
   {
  public function TestClass()
  {
 var o:EventDispatcher = new EventDispatcher();
 o.addEventListener(Event.COMPLETE, _handler);
  }; // At this point o will be marked for
garbage collection, no references to o left.

  private function _handler(e:Event):void
  {
  };
   };
};


Another example (again not usefull, but to illustrate the point):

package
{
   class TestHandler
   {
  public function TestHandler()
  {
  };

  public function handler(e:Event):void
  {
  };
   };
};

package
{
   import flash.display.Sprite;

   class TestClass extends Sprite
   {
  public function TestClass()
  {
 var o:TestHandler = new TestHandler();
 stage.addEventListener(Event.RESIZE, o.handler);

  }; // At this point o will not be marked for garbage collection, stage
will still have a reference to it.
   };
};


I hope you agree on this. If not I am open to convincing arguments :)

I do not completely agree.

>It prevents you from using weak event listeners

Correct.

The common use for weak event
listeners is when adding listeners to the stage: the stage is allways
present and adding normal listeners to it will insure that the
listener will persist. Even if it is removed everywhere else.

In most cases there is actually no real benefit of creating weak event
listeners. In most cases parents add
listeners to their children. Children are removed and that's that. If
the parent gets removed: no problem.

In the majority of the cases, the creation of listeners on a parent is bad
practice (stage is one of those exceptions).

Hmmm, if it was garbage collected, why would I remove the listener, isnt
that the point of weak references?

Re: [Flashcoders] [AS3] Memory leaks & unloading

In Flex Builder 3 they have added the profiler. You can use that to take

Re: [Flashcoders] Passing vars with the the timer and events

[EECOLOR]

If we ever he need to pass extra arguments to the handler we use a delegate
class to pass them. Usage:

obj.addEventListener(Event.TYPE, Delegate.create(this, _handler, arg1,
arg2));

private function _handler(e:Event, arg1:Object, arg2:Object):void
{

};

I added our delegate class as an attachment.

Note that for class methods the scope (first argument of the create method)
has no influence.

Re: [Flashcoders] LoaderContext question

[EECOLOR]

Within Flex builder I got it working like this:

ITestAS.as
package
{
   public interface ITestAS
   {
  function get testVar():String;
   };
};


TestAS1.as
package
{
   import flash.display.DisplayObjectContainer;
   import flash.display.Loader;
   import flash.display.Sprite;
   import flash.events.Event;
   import flash.net.URLRequest;
   public class TestAS1 extends Sprite
   {
  private var _loader:Loader;
  public function TestAS1()
  {
 _loader = new Loader();
 _loader.contentLoaderInfo.addEventListener(Event.COMPLETE,
_loadCompleteHandler);
 _loader.load(new URLRequest("TestAS2.swf"));
  }
  private function _loadCompleteHandler(e:Event):void
  {
 var testAS2:ITestAS = ITestAS(_loader.content);
 trace(testAS2.testVar);
  };
   };
};



TestAS2.as
package
{
   import flash.display.Sprite;

   public class TestAS2 extends Sprite implements ITestAS
   {
  public function TestAS2()
  {
  };
  public function get testVar():String
  {
 return "hello";
  };
   };
};


I recall vaguely that I once tried this with an swf created in the Flash IDE
and that we needed to get the firstChild. You can use describeType to
navigate to content and its children to see where the class you need is
located.

Re: [Flashcoders] BitmapData.paletteMap ()

[EECOLOR]

So if I understand you correctly, your question actually is: "how do I find
out which colors are used in my bitmap data?".

I am sorry to disappoint you, but I do not have an answer for you. The only
solution I could come up with is looping through the pixels (see the code at
the end of the email). This loop however is too slow. On my fast machine it
took about 2.4 seconds for an image of 2000 x 2000. If time is not an issue
you could split the loop over multiple frames so you can show a progress
bar.

Maybe someone has a better idea for you...

Re: [Flashcoders] Question on garbage collection

[EECOLOR]

That all looks fine. There is no memory leak in the code you showed here.

You do not need to delete tTime as it is declared within the scope of the
function and will be marked for deletion as soon as the function is
complete.

If I run the classes (with the line clockdata = new
ClockData() commented out), the memory is stable in the stand alone
player. In flash the memory is slowly going up, but that is because we
are doing a trace each interval.

Note that it takes a few seconds for the memory to be stable.

Re: [Flashcoders] Exporting AS2 classes across multiple frames?

[EECOLOR]

I might be wrong here, but if I recall correctly you can in fact load all
your classes in frame 2. Make sure none of your MovieClips have the 'export
in first frame' option enabled and place those MovieClips in frame 2.

As for your other non-visual classes, just make sure they are not called
within frame 1. Your preloader script in frame one should run before
everything else has been loaded. If I remember well, this is the technique
used in Flex 1.5 and 2.0.

Whow, tough task...

If I were given that assignment I would check out this application:

http://www.sephiroth.it/file_detail.php?id=159#

It allows you to read font information. This font information allows you to
draw the font using information available in the font file itself. If I am
correct the application draws the font using an included graphics library.

If you end up using this for your application I would recommend you to
consider to donate something using the paypal button on that page.

Re: [Flashcoders] Bundle swf's on server for transport to client

[EECOLOR]

>In the Flash app we are having some trouble with the attachMovie method and
the fact that you can only attach a mc on the same parent.

What you could do here (if you are developing for Flash 8) is put a method
in you library like this (might contain errors, wrote it from the top of my
head):

function getImageBitmapData(linkageID:String, width:Number,
height:Number):BitmapData
{
   var currentImage:MovieClip = attachMovie(linkageID, "currentImage", 0);

   var bmd:BitmapData = new BitmapData(width, height);
   bmd.draw(currentImage);

   //remove the movieclip
   currentImage.removeMovieClip();
   //make sure it is removed
   delete this.currentImage;

   return bmd;
};

Then where you use the component you could draw it with attachBitmap or
bitmapFill. I suspect you resize the images aswell. In that case at the end
of the resize just get a new bitmapData (during might be too heavy,
something to test I guess).

Re: [Flashcoders] AS3 type coercion error

[EECOLOR]

The only thing I can think of is that it is most likely
a problem concerning the ApplicationDomain. You probably load the swf into
its own application domain, which means it will use the AbstractPreloader
class of the swf instead of the one in your main application. The solution
here would be to load the swf like this:

var context:LoaderContext = LoaderContext(false,
ApplicationDomain.currentDomain = null, SecurityDomain.currentDomain);

loader.load("my.swf", context);

Re: [Flashcoders] Question about Arrays

This has nothing to do with that, hehe. There is a tiny difference beween
ClassToCastTo(value) and (value as ClassToCastTo). In the first case a
compiler error will be thrown. In the second case the cast will be tried. If
it fails the resulting value will be a null value.

>why is -it- working

The pop method is typed as Object. Object is a dynamic class which means you
can add properties at
runtime. This in turn means that the compiler can not complain about
you calling a property that might not exist as you might be adding it
'dynamically' before you call it,

In most cases you want to prevent the main application from compiling
specific classes used in swf that are loaded
in. Interfaces are a perfect solution here, they act as the contract
between the loader and the loaded.

Re: [Flashcoders] Video has no mouseEnabled, help (AS3)

In case this doesnt help you could also check out the property:
mouseChildren and do something like parent.mouseChildren = false;

Re: [Flashcoders] Catching an error from a component

[EECOLOR]

I am not sure how it is possible that the item has been removed from the
display list. I however take your word for it :) Since you can not put a try
/ catch block (or check) around error area the solutions are limited.

My first thought was to extend the component and override the
thumbReleaseHandler, this method is however most likely private and thus can
not be overridden. You could however try this:

scrollbar.addEventListener(MouseEvent.MOUSE_UP, _listener, false, 1);

function _listener(e:MouseEvent):void
{
   //check if the scrollbar is part of the display list
   if (!scrollbar.stage)
   {
  //It is not in the display list, stop the event from being dispatched
to the default dispatcher
  e.stopImmediatePropagation();
   };
};

In the above code you add a listener that has a higher priority than the
internal listener of the scrollbar. Within the listener you check if the
scrollbar has still has a stage reference (which means it is still part of
the display list).
If it has not, you tell the event dispatcher to stop dispatching the event.

Before you try this code I would urge you to check the setup of your
application as it (usually) should be avoidable to have this error in the
first place.

Re: [Flashcoders] Bundle swf's on server for transport to client

[EECOLOR]

With AS2 this indeed seems
tricky. With AS3 you could just zip the stuff, unzip within your Flash
application and load the bytes. Your best guess is a tool like swfmill
that has
the ability to
create swf's on the server. I only know of a library in java that has
the ability to generate swf's (javaswf).

If the content you are loading in is created within flash you might be able
to convert it to actionscript drawings (think lineTo and beginFill, etc).
This allows you to convert those commands to a text or xml file and run them
in your main application.

Re: [Flashcoders] Event Handling in ActionScript 3

[EECOLOR]

>just can't think of one now.

The most common case where you do not extend the EventDispatcher is when you
need to extend the Proxy class in order to catch dynamic method and property
calls. In that case
you need to extend a class that does not extend EventDispatcher itself
you can do something like this:

public class Test extends Proxy implements IEventDispatcher
{
   private var _eventDispatcher:EventDispatcher;

   public function Test()
   {
  _eventDispatcher = new EventDispatcher(this);
   };

   public function dispatchEvent(event:Event):Boolean
   {
  return _eventDispatcher.dispatchEvent(event);
   };

  public function addEventListener(type:String, listener:Function,
useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean =
false):void
   {
  return _eventDispatcher.addEventListener(type, listener, useCapture,
priority, useWeakReference):void
   };

   ...

};

Re: [Flashcoders] Google Maps or Yahoo maps

[EECOLOR]

A few weeks ago I had to create some map application in Flex 2 aswell. I
went out and started looking for a solution and came across a Flash Player 9
application that could connect with all types of map services including
google. But the source for that application was not available anymore
(apparently ordered by google or something).

I tried to figure it out myself by going over the JavaScript files. This
however would have taken ages as it's quite a complex process that google
uses. You can not just get the images directly, you need to send
somesort of header I guess.


Eventualy I used Yahoo, dug through the scripts and figured out how to load
the images.

I did not come across the G_map component in my search though, I'm not quite
sure how it works but my guess is that you could find out. However this is
on the google API's Terms of Use:

Your use of this photographic imagery is limited to displaying it to end
users within the Service itself, and in the same manner, form, format, and
appearance as it is provided by the Service. You may not, nor may you allow
others to, copy, distribute, display, alter, or otherwise use, this
photographic imagery except as it is provided to you through the Service.


This also the reason that I stopped persuing the better images of Google
maps.

Re: [FlashCoders] AS3 TextFields with filters - game performance?

I do not know what the performance inpact is of TextFields with
filters. If the performance it too great you could take a snapshot
of the text using a BitmapData instance. Then draw that BitmapData to
a Shape or Bitmap and apply the filters there.

As I said, I dont know about the difference in performance, but you could
try it :)

Re: [Flashcoders] XML confusion

[EECOLOR]

The trace functions arguments are implemented as follows trace(...
arguments). Which means that all types of variables are accepted. Every type
of variable extends Object and with that every instance will have a toString
method. This is the method the trace function will call to display the
value.

The actual text from the documentation:

Displays expressions, or writes to log files, while debugging. A single
trace statement can support multiple arguments. If any argument in a trace
statement includes a data type other than a String, the trace function
invokes the associated toString() method for that data type. For example, if
the argument is a Boolean value the trace function invokes Boolean.toString()
and displays the return value.

There are two possible ways to achieve this:

1. Make sure the text is embedded. In order for text to have an alpha value
or rotation is needs to be embedded.
2. Make a 'screenshot' of the text using BitmapData.draw() and animate that.

Yes in AS3 you can move DisplayObjects to other parents without problems.
One thing to note is that you need to remove it from the current display

Something like this:

parent1.removeChild(theClip);
