[Flashcoders] Flash garbage collection
How will Flash's garbage collection handle the following scenario?
function loadAsset(url:String) {
this.createEmptyMovieClip(image_mc, this.getNextHighestDepth());
this.onLoadInit = function(target_mc:MovieClip) {
trace(target_mc + ...loaded);
}
var mcl:MovieClipLoader = new MovieClipLoader();
mcl.addListener(this);;
mcl.loadClip(url);
}
loadAsset(foo.jpg);
loadAsset(bar.swf);
...
What happens to all the instances MovieClipLoader?

[Flashcoders] class file updated, but .aso not updated?
I'm having a problem that is not directly related to a previous thread on this list about ASO files. Here's my inheritance heirarchy... BaseClass - VisualBaseClass - ButtonMessagingBaseClass - CardBase - CardSpecial I'm on a Mac OSX 10.4.8 running Flash Professional v8.0. I've updated CardBase, but the changes don't appear! I've deleted ASO files and that didn't work. I've deleted ASO files, quit Flash, restarted and that didn't work. I also tried to add trace statements all the way up to the parent (BaseClass) and those trace statements don't appear. The other curious bit is that I've checked Omit Trace Actions but the old trace statements in CardBase and the other onces all the way up to the parent (BaseClass) are still showing!!! CardSpecial...the last one in the chain, behaves correctly...changes take effect, when I Omit Trace Action its traces are suppressed! What's going on here? Am I going crazy? Is the Flash file corrupt? (Right now I'm going to try grabbing an older version and see how that behaves) -James ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
Re: [Flashcoders] class file updated, but .aso not updated?
Figured it out: I'm using runtime shared libraries. These are automatically imported in frame 1. The classes in my movie are not exported until frame 5! So, the version of the compiled classes that I'm getting are from the rsl's !!! We're using rsl's to share assets and not code, but one specific rsl it also compiles some of the classes. So, now I'm going into that one and just extracting the assets that will be shared. Whew. I'm so happy that there was a logical explanation. -James On May 24, 2007, at 2:54 PM, James Tu wrote: I'm having a problem that is not directly related to a previous thread on this list about ASO files.

[Flashcoders] class member Array
Has anyone encountered this before...
If you have a class variable that is of type Array...
DO NOT DO THIS:
private var ListOfThings:Array = new Array();
DO THIS:
private var ListOfThings:Array;
//then in your constructor, do this
ListOfThings = new Array();
If you do the former, Flash will create an Array that is SHARED
between all instances of the class!!! (i.e., it makes it STATIC)
I did the former:
//this is in the class declaration section
class Foo
{
private var _pressed_event_message:Array = new Array();
//other stuff omitted
function setPressedEventMessage ( m:String, p:Object ) {
_pressed_event_message.push( { msg:m, param:p} );
trace(this._pressed_event_message.length: +
_pressed_event_message.length);
}
}
class FooExtender extends Foo {
}
When I create two FooExtender instances...and call the
setPressedEventMessage() function, the trace increments as if there
these both instances share the same array!!!
var a=new FooExtender();
var b=new FooExtender();
a.setPressedEventMessage( blah ); //traces
this._pressed_event_message.length: 1
b.setPressedEventMessage( blah ); //traces
this._pressed_event_message.length: 2
a.setPressedEventMessage( blah ); //traces
this._pressed_event_message.length: 3
a.setPressedEventMessage( blah ); //traces
this._pressed_event_message.length: 4
b.setPressedEventMessage( blah ); //traces
this._pressed_event_message.length: 5
b.setPressedEventMessage( blah ); //traces
this._pressed_event_message.length: 6
When I took the initialization out of the variable declaration
section and just did this...
class Foo
{
private var _pressed_event_message:Array;
function Foo () {
_pressed_event_message = new Array();
}
}
All behaved as expected...
Was I not doing something correctly?

Re: [Flashcoders] flash and Arabic
We tried the following: (we're embedding fonts in all cases, also we don't have require any input fields...we're just displaying Arabic) -Copied Arabic text into a static text field...flash actually reverses the characters. So we copied reversed text a static field. Then when we published, it seems that the characters were not being displayed correctly. An arabic reader took a look at it and told us that the arabic characters didn't connect to each other correctly! It's as if you took English script characters and broke them apart! We then tried a few more experiments... - copy and pasted Arabic text (normal order) into a dynamic field...flash flipped it. But when you publish it for Player 8, the order of the text is correct, but the characters looked disjointed again. -We published it for Player 7 and this time everything looked perfect. The order of the text was correct and the characters looked connected!!! We basically have all the text assets in a separate .swf (published for Player 7) and we're using it as a runtime shared library. Our main app is published as Player 8. Has anyone else seen this? Am I not doing something right here? I'm shocked that support for Arabic (and I'm assuming other RTL languages) took a step backwards from Player 7 to Player 8. I wonder what it is in Player 9. -James On Apr 16, 2007, at 7:10 AM, nik crosina wrote: Thank you very much, Danny, Yes I thought that this post sank without a trace, lucky you saw it!

Nik Crosina On 4/16/07, Danny Kodicek [EMAIL PROTECTED] wrote: HI, It now transpires that the project I am quoting for needs much of it done in Arabic. As it is my first multi language project in Flash are there any issues with that in Flash (I could write an encyclopedia full about Director and its characater set issues) Just got back from holiday and noticed this post which doesn't seem to have had any replies. Arabic in Flash is possible but tricky. Exactly how tricky depends on what exactly you need to do. Just putting static Arabic text on screen is easy - no different from Roman. Dynamic text is essentially okay, but you need to watch out for RTL and Bidirectional issues. One major issue is that Flash behaves differently for embedded and non-embedded fonts. Text rendered using non-embedded fonts uses the OS-level text renderer, and so renders the text using the standard Bidirectional algorithm. For single-line text this is perfect (although we didn't test for a very wide range of OS's and browsers - I suspect there might be some niggles on various combinations); for multiple-line text you'll find that line breaks do not get added correctly (words get broken half-way across) so you'll need to add your line breaks directly into the dynamic text. Text rendered using embedded fonts does not render correctly: it has the same line-break issues as before, but also it renders LTR and fails to correctly interpret the Arabic characters into their cursive variants (that is, join them correctly to give the 'handwritten' style that Arabic text should have). There are ways around this, including some code libraries (check out FlashRTL). Personally, I prefer this option as you're in more control - I hate leaving things to the OS unless I absolutely have to! Of course, the above also depends on the *source* of your dynamic text: if you're in complete control, you can store the text directly as the characters that will appear on-screen. But if it's coming from something like an external XML file or some other data source, you'll need to consider these issues. If you want input text, you're in a different kettle of crustaceans. We managed to solve it, but it was a big job. There aren't currently any available commercial solutions to this, but hopefully as soon as I'm finished with my enormous globalisation job that's taken me the best part of a year, we'll be releasing my solution in some form.

Re: [Flashcoders] Scaling Up an Image in Proportion to width or height
I found some code online which I turned into a function... This
should give you the scale whether you are scaling up or down. You
tell it the area you want your mc to fit into and it will give you a
number back...all you have to do is then use that number...example:
mc._xscale = mc._yscale = number_returned_from_function.
Maybe this helps out a bit?
function fitToDimension( sourceWidth:Number, sourceHeight:Number,
targetWidth:Number, targetHeight:Number ):Number {
if ( sourceWidth/targetWidth sourceHeight/targetHeight ) {
//aspect ratio is determined by width
return (targetWidth*100/sourceWidth);
} else {
//aspect ratio is determined by height
return (targetHeight*100/sourceHeight);
}
}

Re: [Flashcoders] Flash and levels
I just tried it and it didn't work.

Re: [Flashcoders] Flash and levels
OK. Thanks for everyone's input! I usually do use movieclips to
nest elemets. A lot of times I'll have each UI screen be
encapsulated in it's own MC so that I can easily do transitions for
the entire screen if needed. I started down the road with _level's
again b/c of an article that I was reading regarding the use of
dynamic shared libraries. It suggested that I preload dynamic shared
libraries into levels before I load movies that I use them...so that
the dsl's are cached...and when I load the movies that use them Flash
won't reload the dsl's.
If I load the dsl's into movieclips instead, flash should still be
caching them right? If I load a movie that uses them into another
movieclip flash should not reload the dynamic shared libraries right?

Anyway, I did this, and it worked:

loadMovieNum(blank.swf, 5);
this.onEnterFrame = function() {
if (_level5 != undefined) {
if (_level5.getBytesTotal() ==
_level5.getBytesTotal()) {
var tmp = _level5.createEmptyMovieClip(foo, 10);
trace(tmp);
delete this.onEnterFrame;
}
}
}
My guess is that you're trying to create a clip on
level 5 before it's fully loaded, and so it's failing.

[Flashcoders] Flash Player 7 and Flash Player 8,9 issues.
We're working on a project that uses Arabic. When we create Dynamic Text Fields and paste in Arabic text, it looks backwards in the authoring env, but when we publish for Player 7, the text reverses itself(correctly) and the glyphs look correct and neighboring glyphs connect to each other correctly. However, when we publish for Player 8 or 9, the text also reverses itselft(correctly), BUT the glyphs look wrong. The characters are totally separate from each other and not connected smoothly.

[Flashcoders] flash and Arabic
We have an approach to deal with a list of 100 phrases in Arabic. When you copy and paste a phrase of Arabic into a Flash textbox, Flash reverses it! So, we first reversed the characters outside of Flash and then copied and pasted the phrases into Flash. Problem solved right? We'll, when someone that can read Arabic read it, they told us that the characters look funny. In essence, the characters weren't connecting to each other correctly! It's as if you took a cursive font and laid out the characters and the cursive writing was not continuous. Does anyone have any suggestions on handling Flash and Arabic? I did some extensive searching and there aren't any definitive solutions...Some suggested using a special Flash Arabic font, which I couldn't find.
