RE: [Flashcoders] re: quick actionscript question
What I'm saying is that you can't fix it from the AS--you have to re-encode the
FLVs with keyframes on every frame.

Mike, Not really getting you, the external .as file controls
everything so how would
we correct it from the as file?
Thanks again,
Eric
The problem is in how the FLVs are encoded. You have to encode with
keyframes on every frame. Once that's done, they should scroll fine
(although backwards is generaly chunkier than forwards).

Hello anyone know the actionscript for a button that will control a

smooth transition? I want to use it with an existing scrubber that is
working. The buttons are working but at present they only go back or
foreard based on 1 or 2 second increments.
Here is what i have at present:
// my custom nav buttons are below
ff_button.onRelease = function (){
myDisplay.jumpToVideoPosition(myDisplay.currentVideoPosition +

rev_button.onRelease = function (){

RE: [Flashcoders] HELP!!! Eventdispatcher and firefox bug????
Ot sounds like it has to do with asynchronous events happening in different orders. Try this--when the XML loads, set a loaded flag on the dispatcher to true and then dispatch a load event. Your listeners should: 1) Check if loaded is true. 2) If so, proceed. 3) If not, listen for the load event. I'll bet what's happening now is that your listeners don't start listening until after the XML has already been loaded--hence they never receive the event. (That said, I could be way off.) ― Mike Keesey -Original Message- From: [EMAIL PROTECTED] [mailto:flashcoders- [EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, November 14, 2006 6:00 PM To: flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] HELP!!!

RE: [Flashcoders] functions outside a class
If these are functions that don't reference a particular instance (i.e.,
don't use the this keyword), then it's better to make a static
utilities class (similar to, e.g., Flash's Math class):
class utils.controls.MyFunctions { // Think of a better name
public static function functionA():Void {
// ...
}
public static function functionB():Void {
// ...
}
}
// In your class:
import utils.controls.MyFunctions;
class utils.controls.ClassA {
public function someFunction():Void {
// ...
MyFunctions.functionA();
MyFunctions.functionB();
}
}

[Flashcoders] Grabbing data directly from the HTML page
I was playing around with the idea of passing data from an HTML page
directly into a Flash movie via Javascript/SWFObject. One thing I wanted
to try was sending the text that SWFObject replaces into the Flash
movie.
In Firefox this was pretty simple. E.g., if SWFObject was replacing the
contents of div id=flash-content.../div, then all that was needed
was something in the Javascript code like:
var swfObj = new SWFObject(parameters);
swfObj.addVariable(HTML_flashContent, escape('div
id=flash-content' +
document.getElementById(flash-content).innerHTML.toString() +
/div));
Then, in Flash, the root variable HTML_flashContent can be parsed into
an XML object. This has obvious benefits for search engine optimization,
as well as making it so a Flash and non-Flash version of a page can be
the exact same file.
Unfortunately, though, Internet Explorer and Safari return SGML, not
XHTML, for the innerHTML property (e.g., the above div tag gets
converted to DIV id=flash-content.../DIV in IE). I made a
quick-and-dirty SGML to XHTML conversion tool to get around this, and it
seems to work so far.
My question is, has anybody else made an SGML to XHTML conversion tool
in ActionScript, or should I continue to refine mine and offer it for
public use when done?

Think of it this way: When you call XML.load(), the XML object doesn't say, Right away, sir, there you go! It says, Okay, let me pencil that in for later and I'll get to it when I can. Once you call XML.load(), you shouldn't use the XML object again until XML.onLoad() is called (which is the XML object's way of telling you that it finally got around to it). (ActionScript 3.0 is a bit nicer with its URLLoader class that dispatches multiple types of events instead of calling a single callback function, but that's another topic.) -- Mike Keesey ___ 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

I prefer the the double underscore naming scheme to differentiate a
local/arugment variable from a class variable. It helps when you want
to
create get/set functions and reminds you that it is a private variable
and
should not accessed directly.
class Student
{
private var __name:String;
public function Student(name:String)
{
__name = name;
}
}
Me, too (well, single underscore), but we were talking about setting
properties, not variables. You might want to set a property in a field
because it has some kind of verification or formatting functionality.
For example:
class mypackage.MyClass {
/**
* Class constructor.
*
* @param nameName for this instance.
* @see #name
*/
public function MyClass(name:String) {
this.name = name;
}
/**
* An upper-case string which is the name for this instance.
*
* pValues are automatically converted to upper-case. May be
* [EMAIL PROTECTED] null}./p
*/
public function get name():String {
return _name;
}
public function set name(value:String):Void {
if (value instanceof String) {
_name = value.toUpperCase();
} else {
_name = null;
}
}

problems
Inside an onEnterFrame function you have to use this when referring
to
things in the class (if the class extends MovieClip, which I hope it
does because only MovieClips can have onEnterFrame as far as I know).
class MyClass
{
var foo:Boolean;
function MyClass()
{
this.onEnterFrame = function()
{
this.foo = !this.foo;
this.traceFoo();
}
}
function traceFoo()
{
trace(foo);
}
}
But you could just write it this way:
class MyClass extends MovieClip {
private var foo:Boolean = false;
public function MyClass() {
}
public function traceFoo() {
trace(foo);
}
private function onEnterFrame():Void {
foo = !foo;
traceFoo();
}
}
Or even like this:
class MyClass extends MovieClip {
private var foo:Boolean = false;
public function MyClass() {
onEnterFrame = toggleAndTraceFoo;
}
public function traceFoo() {
trace(foo);
}
private function toggleAndTraceFoo():Void {
foo = !foo;
traceFoo();
}
}
(Me, I prefer to use an event dispatcher that sends enterFrame events,
but I'll admit that that's often overkill.)

I don't know if it's a remnant.
You may be doing property initialization and need to nail down
scope:
class Student {
private var name:String
function Student( name:String ) {
this.name = name;
}
}
That's just bad coding. Don't use class variable names as argument
names. It's not like you don't have a choice about it. ;)
I don't think it's bad coding. Documentation generated from this
signature might be a bit clearer than documentation generated from a
signature where the argument was, e.g., nameValue, since it would be
more immediately obvious that the argument name corresponds to the
property name. That said, the code itself is clearer the other way.
Six of one and half a dozen of the other. (Programming is so often like
that.)

RE: [Flashcoders] Freelancer Class
They (now Adobe) have pretty much done an about-face on this issue. The ActionScript 3.0 documentation (http://livedocs.macromedia.com/flex/2/langref/ ) is excellent. And they do use the argument name = property name syntax in constructors. For example, http://livedocs.macromedia.com/flex/2/langref/Error.html Error(message:String = , id:int = 0) Creates a new Error object. (Well, the id argument corresponds to the errorID property--so I guess they went both ways on this one!) ― Mike Keesey -Original Message- From: [EMAIL PROTECTED] [mailto:flashcoders- [EMAIL PROTECTED] On Behalf Of Steven Sacks | BLITZ Sent: Tuesday, November 07, 2006 1:34 PM To: Flashcoders mailing list Subject: RE: [Flashcoders] Freelancer Class Pretty much.

Couldn't quite figure out your code Mike so have just rewritten the
copy
function based on what you said:
Well, that was the most important part.
I am however curious to understand the BoardStatus class you wrote.
You
declared a variable of type BoardStatus within BoardStatus. Can you
explain
what you are doing here please.
This was an example of an enumeration class. As I recall, your code had
been storing the status of each Connect-4 square (red, black, or empty)
as a number (0, 1, or 2). The problem with this is that it's easy to
slip it a bad number (e.g., 3, 4, 5, etc.). One solution is to create an
enumeration class.
An enumeration class has a private constructor and a finite number of
instances, generally static constants (or pseudo-constants) associated
with the class. Thus, it is impossible to assign an invalid value to
anything that requires a variable of that class type.
Example (somewhat modified from my previous example):
class connect4.SquareStatus {
private function SquareStatus() {
}
public static var BLACK:SquareStatus = new SquareStatus();
public static var EMPTY:SquareStatus = new SquareStatus();
public static var RED:SquareStatus = new SquareStatus();
}
// Elsewhere:
var status:SquareStatus; // It is impossible to set this variable to
anything but null, undefined, or a valid SquareStatus value.
status = SquareStatus.RED;
Incidentally, you could skip the EMPTY value and just have null signify
an empty square.
In AS3.0, this becomes trickier, since there are no private
constructors. Anyone know if there is a recommended way to get around
this? (On the plus side, you can make the class final and the static
values constant, which is a major shortcoming in AS2.0.)

a
WeatherEvent object carrying the new weather values.
Generally in the code that Macromedia/Adobe writes, event names dont
have on as part of the name, but a function responding to them might,
e.g.:
WeatherManager.instance.addEventListener(windChange,
Delegate.create(this, onWindChange));

Looks pretty good to me! You might consider having the display classes
dispatch an event instead of calling a single function when they
close--then you can extend behavior more easily in the future, if
several things need to happen based on the same event.

Hi,
I've got a simple little game that I'm trying to make with AS2, but
I'm
not sure that I'm doing it right. Here's what I've got so far. I've
used a 'document class' as described here:
http://www.bit-101.com/blog/?p=857
Here's the code in the .fla:
Game.create(this);
In Game.as:
class Game extends MovieClip {
private var splash:Splash;
private var preload:Preload;
private var mainMenu:MainMenu;
private function Game() {
showSplash();
}
public static function create(target:MovieClip):Void {
target.__proto__ = Game.prototype;
Function(Game).apply(target, null);
}
public function showSplash():Void {
Splash.create(this, splash, getNextHighestDepth());
splash.setEndFunction(this, showPreload);
}
public function showPreload():Void {
Preload.create(this, preload, getNextHighestDepth(),
this);
preload.setEndFunction(this, showMainMenu)
}
public function showMainMenu():Void {
MainMenu.create(this, mainMenu,
getNextHighestDepth());
// etc.
}
}
The Splash, Preload and MainMenu classes each have a static function
called create that attaches an instance of their symbol to the stage.
The two setEndFunction functions tell Splash and Preload what call
when
they've finished doing their thing.
Is this a reasonable way of going about things, or am I just making
life hard for myself?
Thanks,
Haydn.

RE: [Flashcoders] Copy Constructor
I don't see anything wrong after a (very) cursory glance.
One red flag, though, is that you are making your variables public. This
means there could be code elsewhere that sets them to be identical to
each other. Because of issues like this, I think it's a good practice
never to make variables public (except in some cases, like static
pseudo-constants in AS2.0; but AS3.0 has real constants, so this problem
goes away). There are two things you could do with an array: 1) make it
read-only, offering a defensive copy with a getter; 2) provide methods
for accessing and updating its data:
1)
public function get board():Array {
return _board.concat();
}
private var _board:Array;
2)
public function getBoardStatus(x:Number; y:Number):Number {
return _board[x][y];
}
public function setBoardStatus(x:Number; y:Number, value:Number):Void {
_board[x][y] = value;
}
Actually, looking at it further, Board should probably be a class
composed by Connect4State. Oh, damn, and I realized why you are having
that problem! See copy function below (it's because you are copying an
array of arrays):
class connect4.BoardStatus {
private function BoardStatus() {
}
public static var BLACK:BoardStatus = new BoardStatus();
public static var EMPTY:BoardStatus = new BoardStatus();
public static var RED:BoardStatus = new BoardStatus();
}
class connect4.Board {
public function Board(source:Board) {
if (source instanceof Board) {
copy(source);
} else {
// Default initialization;
}
}
public function copy(source:Board):Void {
_status = new Array();
for (var i:Number = 0; i source._status.length; ++i) {
_status[i] = source._status[i].concat();
}
}
public function getStatus(row:Number, col:Number):BoardStatus {
return _status[row][col];
}
public function setStatus(row:Number, col:Number,
value:BoardStatus):Void {
_status[row][col] = value;
}
private var _status:Array;
}
class connect4.GameState {
public function GameState(source:GameState) {
if (source instanceof GameState) {
copy(source);
} else {
_board = new Board();
// Initialize other fields.
}
}
public function get board():Board {
return _board;
}
// Other properties.
public function copy(source:GameState):Void {
_board = new Board(source._board);
// Copy other fields.
}
private var _board:Board;
// Other private fields.
}

Perhaps it is easier if I explain what I need:
I am rewriting some Java code into AS2.
Basically I have a class called Connect4State
class Connect4State {
public function Connect4State() {
// -
// Initialize the board array
// --
board = new Array();
code goes here
// --
// Initialize the score array
// --
score = new Array();
code goes here
}
public var board:Array; // A 7 by 6 two dimensional array of
integers representing the state of game
public var score:Array; // A 2 dimensional array of integers
representing the score for the players
}
The Java code has a function called a Copy Constructor that enables
you
to
create new objects that are copies of existing objects. The copy
constructor
for Connect4State just copies the contents of each member variable. It
is
necessary to have a copy constructor for Connect4State because the AI
algorithms use temporary state objects a great deal
This is the copy constructor code translated to AS2
public function Connect4State(state:Connect4State) {
// --
// Copy the board
// --
board = new Array();
for (var i:Number = 0; i 7; i++) {
board[i] = new Array();
for (j:Number = 0; j 6; j++) {
board[i][j] = state.board[i][j];
}
}
// ---
// Copy the scores
// ---
for (var i:Number = 0; i 2; i++) {
score = new Array();
for (var j:Number = 0; j winPlaces; j++) {
score[i][j] = state.score[i][j];
numPieces = state.numPieces;
}
}
}
AS2 seems not to like this as I get the following error
A class must have only one constructor.
public function Connect4State(state:Connect4State)
Anyone suggest an alternative to this Copy Constructor?

RE: [Flashcoders] Copy Constructor
Maybe I'm not quite getting the concept, but a copy constructor should
be a constructor that copies data from another object to the object
being created, right? And (I think) the original poster wanted to know
how to overload constructors in ActionScript so as to have a default
(argument-less) constructor and a copy constructor.
But you can't overload functions in ActionScript. You only get one form
for each method/constructor. But you can make the argument(s) optional,
which is what I did in my example, posted earlier.
In AS3.0, I think the constructor might look more like this:
// ...
function ClassName(source:* = null) {
super();
// ...
if (source is ClassName) {
copy(ClassName(source))
} else {
// Default initialization.
}
}
public function copy(source:ClassName):void {
// Copy data from source to this object.
}
/...
Example of code using this class:
var a:ClassName = new ClassName(); // Default initialization.
// Code that modifies a.
var b:ClassName = new ClassName(a); // Creates a copy of a.
Another possibility is to create a clone() method:
// ...
public function clone():ClassName {
var cloneObj:ClassName = new ClassName();
cloneObj.copy(this);
return cloneObj;
}
// ...

RE: [Flashcoders] Copy Constructor
A call to super() is not required unless you are passing arguments to
the superclass' constructor. Nor is it required that you specify that
you are extending Object. (If you don't specify a superclass, it assumes
Object.) I just do it that way because I'm anal about my code. ;)
Calling super() calls the constructor of the superclass (i.e, parent
class). One instance where you might need it is if the constructor
signatures do not match, e.g.:
class SuperClass extends Object {
public function SuperClass(superValue:Number) {
_superField = superValue;
}
public function get superField():Number {
return _superField;
}
private var _superField:Number;
}
class SubClass extends SuperClass {
public function SuperClass(superValue:Number, subValue:Number) {
super(superValue);
_subField = subValue;
}
public function get subField():Number {
return _subField;
}
private var _subField:Number;
}
The super keyword can also be used to access fields and methods of the
superclass, e.g. where methods have been overridden in the subclass,
e.g.:
public function toString():String {
return super.toString() + extra subclass info;
}

Thanks a million Mike, that works perfectly. I now have a chance of

One question though. I commented out the super(); after reading the

The super() call in the constructor class is not required because
Flash
handles this for you in AS2, and it is handled properly. In AS1 you
had to
call super() to make sure the superclass' constructor was called. The

AS2.
I am fairly new to AS2 so I do not really understand what super() does
but
its all working fine so far as far as I can see.
Can you comment on whether the super() is required?
Thanks

I might do it like this:
class mypackage.Connect4State extends Object {
public function Connect4State(state:Connect4State) {
super();
if (state instanceof Connect4State) {
copy(state);
} else {
board = new Array();
score = new Array();
// Default initialization code.
}
}
public function copy(state:Connect4State):Void {
board = state.board.concat();
score = state.score.concat();
}
public var board:Array;
public var score:Array;
}
Then you could call the construct with or without a parameter.
(Actually, I would never use public variables, but that's another

Subject: RE: [Flashcoders] Copy Constructor
Perhaps it is easier if I explain what I need:
I am rewriting some Java code into AS2.
Basically I have a class called Connect4State
class Connect4State {
public function Connect4State() {
// -
// Initialize the board array
// --
board = new Array();
code goes here
// --
// Initialize the score array
// --
score = new Array();
code goes here
}
public var board:Array; // A 7 by 6 two dimensional array of
integers representing the state of game
public var score:Array; // A 2 dimensional array of integers
representing the score for the players
}
The Java code has a function called a Copy Constructor that
enables
you
to
create new objects that are copies of existing objects. The copy
constructor
for Connect4State just copies the contents of each member variable.
It
is
necessary to have a copy constructor for Connect4State because the
AI
algorithms use temporary state objects a great deal
This is the copy constructor code translated to AS2
public function Connect4State(state:Connect4State) {
// --
// Copy the board
RE: [Flashcoders] terminating hotspots etc
Well, the easiest way to shut off all hotspots (and it's kind of a hack,
but a pretty useful one) is to throw a big, invisible button with
property useHandCursor set to false over everything.
That won't work for motion, though. For motion the most elegant solution
is probably to use a singleton EventDispatcher to control everything:
// MotionDispatcher class
import mx.events.EventDispatcher;
[Event(start)]
[Event(stop)]
function mypackage.MotionController extends EventDispatcher {
private function MotionDispatcher() {
super();
}
public static function get instance():MotionController {
if (_instance == undefined) {
_instance = new MotionController();
}
return _instance;
}
public function get stopped():Boolean {
return _stopped;
}
public function set stopped(value:Boolean):Void {
if (_stopped != Boolean(value)) {
_stopped = Boolean(value);
dispatchEvent({type: _stopped ? stop :
start, target: this});
}
}
private static var _instance:MotionController;
private var _stopped:Boolean = false;
}
// In a motion-controlled movieclip with a timeline animation:
import mx.utils.Delegate;
MotionController.instance.addEventListener(start,
Delegate.create(this, play));
MotionController.instance.addEventListener(stop, Delegate.create(this,
stop));
// To stop all controlled animations:
MotionController.instance.stopped = true;
// To restart all controlled animations:
MotionController.instance.stopped = false;

Hi I have a project that I'd like to convert to class based code but would appreciate some advice on the best approach. Basically I have a routine which attaches a number of library items to the stage and, on either a rollover or press event, tweens these items(images) out in a radial fashion. They optionally return to their initial (overlapping) state. Pretty simple stuff. All of the tweening properties (number nodes, circle radius, duration out, duration in, ease type, etc) are predefined and passed in as a single object. My question is: What is the best way to convert this into a Class? Should I simply have a 'create' method in my class that takes the place of my original method? When attaching large numbers of library items, isn't there a 'speed hit'? Should the tweening objects(basically containers for tween properties) have their own class as well? What's should the getters/setters return/set? Any feedback greatly appreciated!

RE: [Flashcoders] playing audio filetypes other than mp3?
You can use ByteArray in Flash 9 to load any kind of binary data. While you could use this to create image-rendering plugins using BitmapData (or even video-rendering, although I question performance), there's no corresponding SoundData class, is there? So I think, at least as far as sound goes, you're kind of stuck with MP3. ― Mike Keesey -Original Message- From: [EMAIL PROTECTED] [mailto:flashcoders- [EMAIL PROTECTED] On Behalf Of Josh Santangelo Sent: Wednesday, November 01, 2006 3:54 PM To: flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] playing audio filetypes other than mp3?

One way would be to create a subclass of Event that stores the

In this case, though, I wouldn't even do that. You can just use
event.target to determine which button was pressed:
function onPressed(event:Event):void {
var button:Button = Button(event.target);
// Do stuff with button.

If you need to specifically use an index number, I'd attach that to the

Subject: [Flashcoders] AS 3 - event args
Hi there. I am just beginning my adventure into AS 3, and came upon
something.
In AS 2 I used to use a custom delegate class to deal with scope
issues,
but also be able to pass args (in an array, single string, etc) to my
event functions.
So for example, I might have something in AS 2:
// snipped fro ma method
for (var j:Number = 0; j 5; j++) {
this._targetMc[dtBtn + j].onPress =
MyDelegate.create(this, onPressed, j);
}
// event method
function onPressed(i:Number) {
trace(i);
}
So the custom class would allow this to work in my classes.
Now in AS 3 as I have read, the basic delegate class is no longer
needed
as the scope issues are dealt with now.
So how would I go about accomplishing the same thing in AS 3?
passing an arg to an event method?
Thanks!

Actually, the need is dependent on the implementation.
It was my understanding that AS first looks to the local scope for
the
existence of a variable then works up to find it. By using this
you
were explicitly telling flash that the var isn't local to the
function
but rather belongs to the object cutting out a step for the VM.
Therefore, something like the following becomes possible and the
use
of
this becomes necessary:
class MyConstructor {
private var target:MovieClip;
public function MyConstructor (target:MovieClip) {
this.target = target;
}
}
Because you can not do this:
class MyConstructor {
private var target:MovieClip;
public function MyConstructor (target:MovieClip) {
target = target; // ?
}
}
However, depending on your naming conventions you might not have
to
use this if you did something like the following
RE: [Flashcoders] Error check for parseXML()
Good point.
One optional tweak:

xml.ignoreWhite = true;
xml.parseXML(someTextVar);
xml.onLoad = function(success:Boolean):Void {
if (this.status == 0) {
trace(Success!);

Hi,
you should put the conditional in a callback, because when execution
reaches the conditional xml parsing might not have finished parsing.
var xml:XML = new XML();
xml.ignoreWhite = true;
xml.parseXML(someTextVar);
xml.onLoad = function(success:Boolean):Void {
if (xml.status == 0) {
trace(Success!);
} else {
trace(Error in XML! Code: + xml.status);

}
Note that the success argument can be ignored if you're using
functions like parseXML(), because it's got to do with the success of
loading a document using XML.load() or XML.sendAndLoad().

Subject: [Flashcoders] Error check for parseXML()
Hi list...
According to the help docs,
public parseXML(value:String) : Void
doesn't return an integer or anything to indicate successful
parsing
of
the xml. How can I be certain that I've passed in some error free
xml
and it was able to parse?

RE: [Flashcoders] when classes die...
The term is a destructor; and, no, ActionScript doesn't have
destructors, only constructors. The closest it comes is
MovieClip.onUnload()--if your class is a subclass of MovieClip, then you
can just override that. If not, one common practice is to make a
function called destroy():
public function destroy():Void {
// Perform clean-up.
delete this;
}
Then replace all instances of delete instanceOfYourClass; with
instanceOfYourClass.destroy().

MovieClip.onUnload is put there specifically for this kind of purpose.

This code is garbage. The delete operator operates on variables and
not on values. So delete this will just delete a variable called
this within the scope of that function. To remove an object from
memory, you have to remove all references to it. And you can do that
by using delete on each one of those references, or by setting those
variables to some other value.

RE: [Flashcoders] Implicit setters and exceptions in AS2.0
I think that's very well-put. ― Mike Keesey -Original Message- From: [EMAIL PROTECTED] [mailto:flashcoders- [EMAIL PROTECTED] On Behalf Of David Bellerive Sent: Thursday, September 28, 2006 8:22 PM To: flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] Implicit setters and exceptions in AS2.0 Last week, I sent a message to the FlashCoders list asking if validating the values passed to setter methods (in custom classes) was a good practice. After reading on how exceptions work in Java, here's the solution I've decided to use in my setter methods in AS2.0. If the client (the programmer using my custom class) breaks his part of the contract by supplying my setter method with an illegal value, I display an alert in the output window using the trace statement and abort the implicit setter method without assigning the illegal value that was passed to the method. On the other hand, if the implicit setter method is the one breaking the contract (it can't complete it's task for whatever reason), I throw and exception. I've decided to use this method because AS2.0 doesn't support checked and unchecked exceptions like Java. In AS2.0, all exceptions are unchecked, meaning the client isn't forced to catch any exceptions. But when an exception goes uncaught, the function call stack completely aborts. So, using this method, when the client is responsible for breaking the contract (like passing an illegal value to the setter method), he is alerted via the output window in the Flash IDE. This way, he isn't forced to respond to low-risk errors and the function call stack won't abort under any circumstance. However, the client cannot react to this error at runtime. However, when the setter method is the one responsible for breaking the contract, an exception is thrown and the client has to catch it to prevent the function call stack from aborting completely. If the client doesn't catch the exception, the function call stack is emptied and the program probably won't work as expected. However, if the exception is caught (and it should), the client has the possibilty to react to it at runtime. In conclusion, when the error comes from the client only alert the client. When the error comes from the method, throw an exception. Any thoughts or comments on this ? __ Do You Yahoo!? Tired of spam? Yahoo!

RE: [Flashcoders] How do you manage your classes?
Lately I actually copy all packages to a folder within my project's folder. Why? Suppose you have a package and you use it on project A. Later, you use it on project B, and realize there are some issues, so you change some of the code. Project B finishes. Then, later on, you find you have to go back to project A with some tweaks and republish it. Because of changes in the package, there may be problems--at best you will still have to spend time regression testing. Copying your packages to a project-local folder means that you have a secure snapshot of the package. ― Mike Keesey -Original Message- From: [EMAIL PROTECTED] [mailto:flashcoders- [EMAIL PROTECTED] On Behalf Of Dan Rogers Sent: Monday, September 25, 2006 4:36 PM To: Flashcoders mailing list Subject: [Flashcoders] How do you manage your classes? Flashcoders, I've been wondering how other flash developers deal with AS2/AS3 class management on both a project-based and common library level, while addressing the need to package up source code for a given project to deliver to a team member or client. I've used version control before, as well as doing the common classpath thing for shared classes... but when it's time to deliver the source code to someone, I would have to go in and hunt for all the classes I used on a project and copy them to the FLA directory (and recreate the com.package... structure as well). Sometimes it seems faster to simply create the AS files along with the FLA (in a single package), and copy over utility files as needed. But then you get into duplicate classes scattered over multiple projects. Can anyone provide any insight to a system that works well for them? For example, does anyone run custom shell scripts (such as rsync) that sync the current project with the main classpath directory?

RE: [Flashcoders] Implicit Setters: Is validation considered a goodor bad OOP practice ?
This is generally the route I take. The only thing is that it may halt
application flow in unforeseen circumstances, so 1) unit test and beta
test really well and 2) try as much as possible to catch errors in code
that sets the property.

so if it's a bad input, it cannot tell the object
that is modifying the setter property that something went wrong.
Not sure if it's the best practice, but if someone passes in a bad
input
to
your setter, in AS3 you can throw errors, such as:
public function set volume( val:Number ) {
if ( val == bad_news ) {
throw new Error( Volume Class - set volume(): Bad value passed

}

It's called defensive programming. Try to have your API as much

For instance any other component of your application (an UI for

Look into MovieClip.getBounds() and MovieClip.getRect(). For example,
you could use:

// ...
function getCenter(shape:MovieClip):Point {
var bounds:Object = shape.getBounds(this);
var center:Point = new Point();
center.x = (bounds.xMax - bounds.xMin) / 2;
center.y = (bounds.yMax - bounds.yMin) / 2;
return center;
}
(Assuming that the scope of this function is a movie clip timeline or a

Subject: [Flashcoders] Algorithm to find center of an irregular
shape
All,
I'm not too handy with geometry, so I'm not even sure this is
possible, but I'm looking for an algorithm that will determine the
center of an irregular shape.
I'm not even sure there is a meaningful definition of a center, but
I'd like to at least find a point that is within the area of the
shape. (I realize that with certain shapes, like a donut, this might
be an intractible problem), so even some rough approximation would
help.
In this particular application, the shapes are the areas between the
lines created when graphing several time series on a chart (e.g., the
price of several stocks, graphed over time)
Many thanks in advance for any advice or insights!
Cheers,
Matt Stuehler

RE: [Flashcoders] HTTP post request in the background
Actually, scratch that -- move the whole formData deal to its own
function, and call that from onMailComplete(). IOW, do the calls
sequentially, not simultaneously.

onResponseComplete is probably being called before
onMailDataResponseComplete (damn that's a long name! onMailComplete
would suffice, no?), and thus unloading the whole SWF as it loads a
new
HTML page.
Try moving this line:
formData.sendAndLoad(http://www.salescloser.com/XMLAddContact.aspx;,

RE: [Flashcoders] Associate clip with class
One technique I've been trying lately is to assert linkage of class
names. First I create a static function that asserts that a symbol is
linked to a certain class. It returns the symbol ID if so, and throws an
error if not:
class com.exopolis.exosite.errors.SymbolError extends Error {
//...
public static function assertRegistered(linkageID:String,
classFunc:Function,
className:String):String {
if (!Object.registerClass(linkageID, classFunc)) {
throw new SymbolError(linkageID, className);
}
return linkageID;
}
}
Then in any MovieClip subclass, I can do something like this:
import com.exopolis.exosite.errors.SymbolError;
class mypackage.MyComponent extends MovieClip {
//...
public static var LINKAGE_ID:String
= SymbolError.assertRegistered(MyComponent,
MyComponent,
MyComponent);
}
That way, the symbol is automatically registered to the class, and if
there is no such symbol, an error is thrown (which does not disrupt any
other processes).

RE: [Flashcoders] specifying type of an array contents?
One technique I often use is to create the array as a private member of
a class and guard it against including invalid classes. For example:
import mypackage.Item;
class mypackage.ItemList extends Object {
public function ItemList() {
super();
_items = new Array();
}
public function get itemCount():Number {
return _items.length;
}
public function addItem(item:Item):Void {
if (!(item instanceof Item)) {
throw new Error(Invalid item: + item);
}
_items.push(item);
}
public function getItem(index:Number):Item {
var item:Item = Item(_items[index]);
return (item == undefined) ? null : item;
}
public function removeItem(item:Item):Void {
for (var i:Number = _items.length; i 0; --i) {
if (_items[i - 1] == item) {
_items.splice(i - 1, 1);
}
}
}
public function removeItemAt(index:Number):Void {
_items.splice(index, 1);
}
public function toString():String {
return [type ItemList(items= + _items.join(, ) + )]
;
}
private var _items;
}
It is cumbersome to do this for all types, but it's handy for many
occasions. (I do really miss C++ templates, though)

Why not just:

?
A tad more concise (you don't need the ? true : false part), and
avoids the problem your function has that if str is null or undefined,
it returns true.

Hi,
Try this for checking if one string contains another:
public static function contains(str:String, val:String):Boolean {
return str.indexOf(val) != -1 ? true : false;
}
Also, try to avoid attaching your functions directly to buttons, as it
makes
scoping tricky:
this.opened_btn.onRelease=function(){
Check out the Proxy class here for a better way to handle that:

RE: [Flashcoders] classes vs external .as files
Far more errors can be caught compile-time using classes than using
timeline script. Rather than finding out halfway into a project that
you've mistyped a variable's name in several places, you find out the
first time you try to compile.
Classes also make for easier unit testing.
I think it's generally better to extend the MovieClip class and register
the symbol to the class than to create classes that refer to movie clips
and assign them via timeline code. The latter approach faces more
problems when the movie structure changes.
In some ways it's also good to keep in line with what Adobe is doing.
Are they making classes? Yes. Are they making scripts to be included
from the timeline? No.
There is only one instance where I currently use an included timeline
script instead of a class, and that is for SWFObject's
expressinstall.as, which needs to work in Flash Player 6r65.

RE: [Flashcoders] Singleton not always Singleton?
PET PEEVE ALERT
class com.shell.util.IntroAnimProxy
Unless you are actually doing Shell Petroleum's website at
http://shell.com, this isn't a proper name for the package. The com
convention is a strategy to keep package paths from overlapping on
different projects: if you're doing a website, you take the domain and
reverse it--voila, you have a path that nobody else will ever use, and
you don't ever have to worry about conflicts. (Assuming everyone sticks
by the convention, of course.)
I've even seen people make classes like com.MyClass, as if com stood
for component or something. (It stands for commercial.)
If you're not working on a website project, then you have a couple of
options:
1) Make a new package for the project in your own domain's package.
(e.g., net.mywebsite.mynewproject) or your client's domain package.
Even if it's not going on the web, you can still guarantee it won't
conflict with any other packages.
2) Make a package that doesn't start with any top-level domain strings
(com, org, net, country codes, etc.)
I'll own that in this instance you'll only really have a problem if,
some day, you *do* work on http://shell.com, but still
(And if this *is* for Shell Petroleum, then I'll shut up now.)

It ends when you make your own damn third-party tools! ;) Seriously, though, I don't find that I have to comment out huge swaths of class functions at a time very often. Even if I did have to comment out several functions, they might not be next to each other, anyway. And, as I said before, commenting out a single function is *easier* when each one is preceded by a block comment--one keystroke of backspace or delete (unless it's the very last function).

[Flashcoders] UML Diagrams
Just curious, What do people on this use to create UML diagrams? Do you use a WYSIWYG diagram-creating tool (preferrably which can output skeletal AS class code)? Or do you use something that scans preexisting AS classes and generates UML diagrams (or a UML-related XML format, like UXF). I've experimented with a few such programs. I'd really like to find something (or a combo solution) that can work both ways. -- Mike Keesey ___ 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

Subject: [Flashcoders] Protect model setters from being called by any
classexcept Controller
Hi,
I have a model class that has a bunch of getters and setters.
Example:
private var _prop:Object;
function get prop():Object {
return _prop;
}
function set prop(p:Object) {
_prop = p;
}
I have a controller class that instantiates that model.
I'm wondering if there is some way to prevent any other class from using
the setter methods of the model except the controller class. They still
should be able to access the getters.
I want to prevent future developers from being able to access the model
setters from anywhere except the controller in order to enforce proper
MVC patterns.
Thanks!

RE: [Flashcoders] Protect model setters from being called by anyclassexcept Controller
Wait--that doesn't expose the getters. H...
Okay, substitute the interface with a superclass (say, AbstractModel)
that has the getters, but not the setters. Then expose the Model object
as AbstractModel everywhere except inside the Control class.
I've never tried that, but I think it should work. A bit weird, though.

RE: [Flashcoders] Dynamically Upcast to a class in the _global tree?
What would be the point of that? The only point of upcasting is to have
things compile with strict typing, and the compiler can't tell what the
class is if it's dynamically determined.
Are you talking about dynamic *instantiation*? Then you could use
something like this:
// Import all classes that may be needed.
import mygroup.mypackage.mysubpackage.MyClass;
// Set up variables.
var packagePath:String = mygroup.mypackage.mysubpackage;
var className:String = MyClass;
// Get the class' constructor function.
var classFunc:Function = getClass(packagePath, className);
// Instantiate a test object.
var test:Object = new classFunc();
// Test the instantiation; should output result of MyClass.toString().
trace(test);
/**
* Returns a class' constructor function, given the package path
* and the class' name.
*
* pClasses must be imported or they will not be found.
*
* @param packagePath path of the package, e.g. [EMAIL PROTECTED]
flash.geom}
* @param className name of the class, e.g. [EMAIL PROTECTED]
Point}
* @return constructor function, or [EMAIL PROTECTED] undefined}
*/
function getClass(packagePath:String, className:String):Function {
var package:Object = getPackage(packagePath);
return package[className];
}
/**
* Returns a class package, given its path.
*
* @param packagePath path of the package, e.g. [EMAIL PROTECTED]
flash.geom}
* @return class package ([EMAIL PROTECTED] Object} instance), or
* [EMAIL PROTECTED] undefined}
* @see#getClass
*/
function getPackage(path:String):Object {
var package:Object = _global;
var pathArray:Array = path.split(.);
for (var i:Number = 0; i pathArray.length; ++i) {
package = package[pathArray[i]];
}
return package;
}

RE: [Flashcoders] Flash/Actionscript Coding conventions
Putting a block comment before a function is standard, though (Javadoc).
Putting one *inside* a function is awful, though, I agree.
/**
* This is a perfectly fine Javadoc comment
*
* @param bar some parameter
*/
public function foo(bar:Object):Void {
/* Using a block comment here is totally bogus. */
// Line comments, though, are great!

I have an issue with coders who put block comments in the middle of
their code, such as:
/***
** SOME COMMENTS
**/
function foo() {
trace(hello world);
}
Or even worse:
/***
** SOME COMMENTS
**/
function foo() {
/* some comments inside the code */
trace(hello world);
}
People who comment like that are my bane and here is why. Commenting
like that in your code makes it completely impossible to easily and
completely comment out blocks of code using /* */ because they have
their */ inside their comments. Believe it or not, this is a very
important tool in debugging.
So, please do everyone a favor and only use block comments before and
after your code and use line comments // for all comments inside your
code. :)
Thanks,
Steven

RE: [Flashcoders] Flash/Actionscript Coding conventions
So you never look at the Flash help code? You just open the .as files and trawl through them? And to the point about Javadoc, I'm not going to ruin my code and handicap my debugging ability to satisfy some poorly thought out requirement of a 3rd party tool. They require you to use block commenting in your code to automatically write documentation and that's counterproductive to actual coding. It should work hand in hand with not diametrically opposed to the coding process. If they were smart about it, they would support line commenting with non-asterisk delimiters. Say //! !//, or //| |// or //[ ]//, etc. Exclamations, pipes, and brackets are all better choices because they do not conflict with anything. I am totally confused by your raging asteriskism. What do asterisks conflict with that those do not? What's wrong with asterisks? I actually like having block comments before functions because it makes it ridiculously easy to comment out a function. Just remove the last / (assuming there's a block comment after the function as well; if not you have to add a */). Makes it very easy to do Move Method refactorings and suchlike. I'm not going to make my process suffer nor am I going to litter my code with ugly asterisks just to document my work when I can spend that energy writing cleaner, easier to read code with light commenting in the code itself. :) I still don't understand how Javadoc makes your process suffer. -- Mike Keesey ___ 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] vars with $
I have seen others do it, or mark parameters with a p_.
I prefer not to mark parameters in any special way. I mark private
variables with _, so those are already distinct. And if I have a
function that's so long that I can't see the top from somewhere in the
body, it's well past time to cut it down into more manageable chunks.
Plus, using $ makes it more confusing when switching between PHP or
Perl (or another language that uses $ to mark all variables) and
ActionScript.

I've used it to indicate arguments in a function to clarify the origin

function myFunc($arg1,$arg2){

}
I don't know where I picked that up, but for me it makes the code easier

use
the underscore for the same purpose, but that can confuse things since
ActionScript uses that for some native properties (_x,_y).

Re: [Flashcoders] init TextFormat prop in a class
Quoting Mendelsohn, Michael [EMAIL PROTECTED]:
Hi list...
Why is it that when I try to init a prop for my class, I get this error:
A class's instance variables may only be initialized to compile-time
constant expressions.
What exactly does that mean?
class test{
private var tf:TextFormat = new TextFormat();
function test(){
trace(hello);
}
}
new TextFormat() is not a constant expression, like null or 3 or
Math.PI
or 2 * Math.PI or 'string text'. Each time you use those expressions it
evaluates to the same value, but each time you use new TextFormat() it
creates a new object. You have to instantiate nonconstant fields in the
constructor:
class Test {
private var _tf:TextFormat;
public function Test(){
super();
_tf = new TextFormat();
trace(hello);
}
}
(The super(); is not strictly necessary; I'm just anal.)
