Re: [Flashcoders] When is 1 not 1?
When 1 had line feeds... Well, I'm not quite sure how yet but somehow I'm getting a couple of line feeds in my def variable when it comes back to the LoadVars.onLoad. I do: $defUser = 1; echo(im=.$fName.def=.$defUser); But I found I get 1 plus a couple of line feeds... I sure like AMFPHP a whole lot better.

[Flashcoders] attachMovie(LibrarySymbol). Right way to access custom clip variables and functions.
Hey!
Consider this.
There is a symbol in the library - Ball.
It has a variable declared in the first frame - size.
I want to instantiate the symbol and then read the variable value.
Trying to access the variable synchronously, right after the the symbol has
been instantiated, does not work:
var ball_mc = _root.attachMovie(Ball, ball_mc,
_root.getNextHighestDepth());
trace(size = + ball_mc.size); //size = undefined
Then I came up with the following solution.
In the first frame of Ball symbol, at the end of code I insert the
following statement
onLoad();
And then inside the main program I register the listener to onLoad()
funciton call.
var ball_mc = _root.attachMovie(Ball, ball_mc,
_root.getNextHighestDepth());
ball_mc.onLoad = function() {
trace(size = + ball_mc.size); //size = 20
}
This technique works fine.
However, I don't like the fact that I have manually add onLoad() call to
every symbol which properties or functions I want to access.
Do you think this is the right way to solve the problem?
What is the best way to?

Re: [Flashcoders] getBounds AS3/AS2 issue
Further to this (again) I've investigated the whole thing in some depth, and come up with this: The bug affects the AS2 MovieClip.getBounds() and MovieClip.getRect() methods. As far as I can tell, it only happens in this situation: AppA is an _AS3_ application. AppA loads AppB. AppB is an AS2 application. AppB loads AppC. AppC is an AS2 application. If you run AppA, then any getBounds() or getRect() calls on objects in AppC fail, but they work as expected in AppB. (If you just run AppB, then everything works as expected.) I've tried various variants of this; if, instead of loading AppB, you embed it into AppA at compile-time, the problem still occurs. It appears to be something to do with loading one VM1 movie into another one within a VM2 shell. For the curious, here's a Zip containing a minimal test setup: http://www.wildwinter.net/public/getBoundsBug.zip All suggestions for workarounds welcomed, as this is a real nuisance for what we're currently working on. (For reference, this is in Flash Player 9,0,115,0, using either Flex compiler 2.01 or Flex Compiler 3.0 for the AS3 and using Flash 8.0 or MTASC for the AS2.) Cheers, Ian P.S.

[Flashcoders] Loading Flash 8 swfs into Flash 9 and GC
Hi, Im building an AS3 Flash 9 app. One requirement is to allow loading of swf ads into the application. I am a little concerned about GC. If the ad has any event listeners attached to the stage, my understanding is that I will not be able to clean up after the ad has finished and will leave myself open to memory leaks. Can anyone validate this? And if this is true, is this also true of loading in Flash 8 and less content.

Re: [Flashcoders] Flash is full of surprises. I will show you how to move movie-clip using a reference to another deleted clip.
So, the case he brought up was different from what you said.
In your case you're creating differently named movie clips, and
explicitly assigning them to the mc variable.
In the original code, a new movie clip was attached with the same
name, but NOT assigned to the variable. After doing so you would
expect the variable to not work, but it ended up pointing to the new
clip.

How else would you expect to be able to attach movieclips and manipulate

e.g.
function doClips() {
var mc:MovieClip;
for(var i = 0;i 10;i++) {
mc = attachMovie(star, star_mc_ + i, getNextHighestDepth());
//mc.removeClip();
mx._x = 100 * i;
}
//would expect to manipulate the last one.
mc._y = 100;
}
doClips();
//compile error, but would not work anyway.
mc._y = 200;
//would work.
star_mc_9._y = 200;
I bet the reference goes out of scope once you exit the function you are in?
If not, then that maybe a bug.

'mc' becomes a dangling reference, which means it'll be looking

The second clip moves!
That is, the second clip was referenced using mc.
Dereferencing 'mc' here yelds the new Star insatnce, having

Re: [Flashcoders] Flash is full of surprises. I will show you how to move movie-clip using a reference to another deleted clip.
Yes, but my example was meant to be different to demonstrate there is
probably a reason for allowing different clips to be assigned to a
variable.
My argument was, the original post may have been moot / redundant /
not-so-surprising if you think a little about how Flash works. Once the
variable goes out of scope, you probably cannot manipulate any clips
through this variable any more. I would also expect that if you create
movie clips with the same names, you are going to run into problems -
the name of the movie clip corresponds to a variable in the parent clip
- assign one thing to this variable and you can manipulate it, assign
another and you would expect to manipulate that - not surprising at all.

How else would you expect to be able to attach movieclips and manipulate
them in a loop as you would normally?
e.g.
function doClips() {
var mc:MovieClip;
for(var i = 0;i 10;i++) {
mc = attachMovie(star, star_mc_ + i, getNextHighestDepth());
//mc.removeClip();
mx._x = 100 * i;
}
//would expect to manipulate the last one.
mc._y = 100;
}
doClips();
//compile error, but would not work anyway.
mc._y = 200;
//would work.
star_mc_9._y = 200;
I bet the reference goes out of scope once you exit the function you are in?
If not, then that maybe a bug.

'mc' is a soft reference to the Star instance.

'mc' becomes a dangling reference, which means it'll be looking
for a substitute with same target name when dereferenced.
//Create another star clip once again with the same name star_mc
//Notice that I do not assign the clip reference to mc variable.
_root.attachMovie(Star, star_mc, _root.getNextHighestDepth());

The second clip moves!
That is, the second clip was referenced using mc.
Dereferencing 'mc' here yelds the new Star insatnce, having
the same target path as the original one.

[Flashcoders] Need HELP...Masking Tween in actionscript3 for animating purposes..
Hello everyone,
This is my first message, and before I begin, I would like to thank the
creator(s) of this mailing list.
I have begun working with AS3 and I am getting comfortalble with the
basics. I can put my MCs on the stage through actionscript, designate
coordinates/placement of MCs, and apply copy motions from the timeline.
so i am able to add event listeners and get the MCs to animate, play
sounds, etc.
I need help with a new class/method..im not sure what to refer it to as
but i will explain.
I attempted to copy motion a mask tween of a circle in the time line,
only to find out that i am not able to. after research i have found
that i can do this in actionscript and have found the following
information about mask tween in AS
the following is my current code structure, and i would very much
appreciate some guidance in this, as to where i should place the codes
at to create a mask effect within a mc, i think...
plain english request :Pi want to animate the rays of the sun. i
have a circle that has lines going away from it. so my idea is to
create a code in actionscript, where it creates an animation of mask
circle, twening from the first fame of animation, to the last frame and
then stop. the circle mask is the same size as the sun. so i want to
add an eventlistener to the sun movie clip that when mouseclick release,
it will animate the shape tween of the circle mask an then stop when it
reaches its final size. beginning size = 100,100, radius final size =
300,300, radius .
can ayone help me get started on the basics of how to implement this?
as i send this email out, i will continue to make attempts. thank you
all for taking a look at this.

[Flashcoders] clean scripting
hi
just a semantic question really
when writing your classes, would you only declare variables in the
class and assign variables later or would you assign values straight
away if you had them?
so for instance, would you...:
package com.receptacle.timeline
{
//package imports
import flash.display.Sprite;
internal class Class extends Sprite
{
// class variable declarations
private var cp:CommonProperties = new CommonProperties();
private var commonY:uint = cp. commonY;
private var commonCopy:String = cp.commonCopy;
private static var title:String = Title;
private static var subtitle:String = Subtitle;
public function Class()
{
myFunc1();
}
private function myFunc1()
{
trace (function ran);
trace (commonY is +commonY);
trace (commonCopy is +commonCopy);
trace (title is +title);
trace (subtitle is +subtitle);
}
}
}
which works fine but is a little messy at the class level
or would you...:
package com.receptacle.timeline
{
//package imports
import flash.display.Sprite;
internal class Class extends Sprite
{
// class variable declarations
private var cp:CommonProperties;
private var commonY:uint;
private var commonCopy:String
private static var title:String

{

}
private function setVars()
{
cp = new CommonProperties();
commonY = cp. commonY;
commonCopy = cp.commonCopy;

}

{
trace (function ran);
trace (commonY is +commonY);
trace (commonCopy is +commonCopy);

Re: [Flashcoders] clean scripting
Not sure if this is correct for AS3, but I was under the impression that there was an actual performance penalty to doing things the first way (object creation and assignment in the class definition rather than in the methods or the constructor). Still, I like doing things the 2nd way, if only because it's habit for me at this point. In my own twisted little mind it also prevents me from experiencing the Where the hell did I define that syndrome --- I always know where I set the initial values of my class variables.

Re: [Flashcoders] clean scripting
Either way to me is a non-issue.
However, it is an issue if I want to implement lazy instantiation. That
is, instantiating objects only right before you need them.
Thus, in your first example, the bulk of instantiation occurs up-front.

An Array is a linear collection. A Hash is a random access collection
(lookup table) of name-value pairs.
Dictionary is a fancy Hash that can take an Object as a key, instead of
a String, and uses strict (===) equality for its lookups.
hash = new Object();
hash.foo = bar;
array = new Array();
array.push(hello);

dictionary[hash] = array;

Re: [Flashcoders] clean scripting
they're both eager, though, aren't they?
the only difference is that everything is instantiated in the first
method of the class rather than in the class head

However, it is an issue if I want to implement lazy instantiation.
That is, instantiating objects only right before you need them.
Thus, in your first example, the bulk of instantiation occurs up-
front.

RE: [Flashcoders] dictionary vs array
The best use for them is to be able to find something you've stored by
its key - as opposed to having to loop through an entire array to find
it.
Pretty damn handy, but sorting them can be complicated.

RE: [Flashcoders] Is there any grid component in AS 3.0
As far as getting the tools to get started, FlashDevelop + Flex SDK is a free option. As for getting started, I would start at the Adobe Developer Connection, specifically the Getting Started tab in the Flex section: http://www.adobe.com/devnet/flex/ If you want books, Adobe Flex 2: Training from the Source is a good tutorial book. If you have a Lynda.com subscription, that's also a good place to start. I think you can get free trial subscriptions for 30 days or something as well.

To clarify, this difference only matters in the case of static class
members. Anything non-static gets initialized at constructor-time
regardless -- the difference is syntax only.

Re: [Flashcoders] clean scripting
Allthough the following no longer seems to apply in AS3, it might be good to
know.
In AS2, if you have the following class:
class MyClass {
private var myArray:Array = new Array();
public function addItem(item:Object) {
myArray.push(item);
}
public function get data():Array {
return myArray;
}
}
The myArray class member will be shared across ALL instances of the class.

Re: [Flashcoders] Is there any grid component in AS 3.0
Flex 3 = Flex 2 but better ;-) Books on Flex 2 should apply to Flex 3 as well, as the language (AS3) hasn't changed. - Original Message - From: anuj sharma [EMAIL PROTECTED] To: Flash Coders List flashcoders@chattyfig.figleaf.com Sent: Tuesday, March 11, 2008 10:51 PM Subject: Re: [Flashcoders] Is there any grid component in AS 3.0 One more question guys.

Re: [Flashcoders] clean scripting
thanks for your input everyone
i've gone for the second option because i can template it out better
and it looks way neater (plus i can still keep all of my
declarations in one place, the setVars() method)
thanks again
here's a copy of my template if you'd like it
//code:
package com.receptacle.timeline
{
//package imports
internal class Class
{
// class variable declarations
// constructor
public function Constructor()
{
setVars();
}
// set class variables
private function setVars()
{
}
}
}
//code

Instanciate at the point you need it, and clear if no longer needed.
It also keep memory use limited.

hi
just a semantic question really
when writing your classes, would you only declare variables in
the class and
assign variables later or would you assign values straight away
if you had
them?
so for instance, would you...:
package com.receptacle.timeline
{
//package imports
import flash.display.Sprite;
internal class Class extends Sprite
{
// class variable declarations
private var cp:CommonProperties = new
CommonProperties();
private var commonY:uint = cp. commonY;
private var commonCopy:String = cp.commonCopy;
private static var title:String = Title;
private static var subtitle:String = Subtitle;
public function Class()
{
myFunc1();
}
private function myFunc1()
{
trace (function ran);
trace (commonY is +commonY);
trace (commonCopy is +commonCopy);
trace (title is +title);
trace (subtitle is +subtitle);
}
}
}
which works fine but is a little messy at the class level
or would you...:
package com.receptacle.timeline
{
//package imports
import flash.display.Sprite;
internal class Class extends Sprite
{
// class variable declarations
private var cp:CommonProperties;
private var commonY:uint;
private var commonCopy:String
private static var title:String
private static var subtitle:String ;
public function Class()
{
setVars();
myFunc1();
}
private function setVars()
{
cp = new CommonProperties();
commonY = cp. commonY;
commonCopy = cp.commonCopy;
title = Title;
subtitle = Subtitle;
}
private function myFunc1()
{
trace (function ran);
trace (commonY is +commonY);
trace (commonCopy is +commonCopy);
trace (title is +title);
trace (subtitle is +subtitle);
}
}
}
which seems cleaner but is more round the houses.
thanks in advance

[Flashcoders] Debugging issue
Hi I am trying to debug my project and it gives me long weird message as follows. Its saying some Security Sandbox violation.

I am loading external videos in myUILoader component using XML.All of those directories are in the same folder. Does anyone has any idea how would i fix that. I bet you're running on Windows Vista. I've had the same problem--publish, double-click the HTML file, and I get the security sandbox violation error. Yet it runs fine in the IDE. It so happens that I'm developing in Flex, using FlexBuilder 3. I haven't seen the same thing in Flash, but then, I haven't been using Flash that much since I got my Vista machine--most of my gigs these days are Flex gigs, or for clients who just want a swf and html, and don't care what environment I use. (I'm not saying Flex is better than Flash, but, as a long-time code monkey, I like the IDE better than Flash). I don't know what the answer is. The producers I work with use XP, and it runs fine for them. One clue--the error I get is on IE7. Firefox gives a more descriptive error--it says that I have an .htm file trying to communicate with a .swf. The .htm file in question is a fairly complex JavaScript file--I didn't write it, so I'm not entirely sure what it's doing, so no help there. This may help, though: it says To let this application communicate with the Internet, click Settings. Long story short, try it in a different browser and see if you get a better error message.

Oh, another thing I noticed--you have a lot of spaces in your file names. That's not a good idea for Internet apps. Concatenate, or use an underscore instead.

Re: [Flashcoders] clean scripting
I'm going to chime in here.
Lazy Instantiation is an irrelevant argument when you're instantiating
in the constructor. What you perceive as cleaner is merely philosophical.
var container:Sprite = new Sprite();
vs
var container:Sprite;
public function ClassName()
{
container = new Sprite();
}
I think the single line version is cleaner. In fact, I would argue that
instantiating classes in their variable declaration is a very specific
way of making it extremely clear that those variables are being made
available immediately to the class, and anything that does not have a
definition is going to be lazily instantiated later.
I'm a big fan of this type of coding practice where the meaning is
derived from the style.
My 2 cents,
Steven

RE: [Flashcoders] clean scripting
Muzak,
Maybe I missed something, but instance2 in your example has no data. Only
static members can be shared across all instances - did you mean...
class MyClass
{
private static var myArray:Array = new Array();
public function addItem(item:Object)
{
MyClass.myArray.push(item);
}
public function get data():Array
{
return MyClass.myArray;
}
}

Jesse

Allthough the following no longer seems to apply in AS3, it might be good to
know.
In AS2, if you have the following class:
class MyClass {
private var myArray:Array = new Array();
public function addItem(item:Object) {
myArray.push(item);
}
public function get data():Array {
return myArray;
}
}
The myArray class member will be shared across ALL instances of the class.
var instance1:MyClass = new MyClass();
var instance2:MyClass = new MyClass();
instance1.addItem(Hello World);
trace(instance1.data);
trace(instance2.data);
//output:
Hello World
Hello World

Muzak did.

RE: [Flashcoders] clean scripting
I agree with Steven. You may want to put your variable declarations in
another function when they either get suuuper messy or you need more data
(ie. stage.stageWidth).
Going back to style... typically I like to run an INIT() in the constructor
and then break down the tasks into INIT_name(). It cleans up the top pretty
well and makes the code very easy to read/understand.
package
{
import flash.display.Sprite;
import flash.events.MouseEvent;
public class MyClass extends Sprite
{
public static var prop:Number = 0;
public var solid:Sprite;
public function MyClass()
{
INIT();
}
// ___
EVENTS
private function click ( e:MouseEvent ):void
{
//...
}
// ___
INITIALIZE
private function INIT ():void
{
INIT_clips();
INIT_vars();
}
private function INIT_clips ():void
{
solid.addEventListener ( MouseEvent.CLICK,
click );
}
private function INIT_vars ():void
{
// ...
}
}
}
2 more cents,
Jesse
