ActionScript 3.0 :: Error On Using An Untyped Parameter In The Constructor Of A Document Class?
Aug 9, 2010
I got an error like "Incorrect number of arguments.. Expected 0." when I was trying to make an instance of a user-defined class that I've written in the document class of my project.Here's the line in my document class:private var myNotice:myNoticeClass = new myNoticeClass(this);An untyped parameter is supposed to be the only argument to the constructor method of class myNoticeClass and the constructor is something like this
public function myNoticeClass(ref:*)
{ ......
}
[code].....

I'm almost certain that creating and accessing untyped data causes some performance penalty vs typing data properly. I am creating a class that accepts an untyped data in the constructor, and assigns that data to a local class variable as such (pseudo code):
class myClass{
private var foo:*;
function myClass(inData:*){
[Code].....
To my understanding, im just passing the 'reference' of the stage or some display container into myClass right?
Even if there is a performance hit, it would upon class instantiation when myClass is created where the untyped foo is created. So, in thats the case, using untyped data for foo won't effect performance? Since there is no direct accessing of foo?
Or is there 'access' on foo in the update function since update() resides in MyClass and so does foo. It wouldn't matter much if its just a normal class but my whole application's update works in this class so if there is any performance issues, it's gonna effect everything else.

I'm learning how to work with a document class. Using the class below, I am learning that this initiates immediately when running the Fla. The problem is that the "scrol" Movieclip is not present in the first frame, which is a menu with a list of topics. Scrol comes later in and is in it's own section/frame label and goes to that section when selected from the main menu of topics.
Is there a way I could call this action only when the Movieclip is present or when that section is shown? Also, I'd like to apply it to other movieclips, not just scrol. Underneath se = new SwipeEngine(scrol,400,0); can I just add a duplicate line but change the mc name? A possible concern is that the mcs may be different sizes in length and might not need to scroll as far.

I've got a simple program that consist of a document class and a buttonTemplate constructor class. I need to call a function called updateText that should be in the document class, when someone clicks on a button. My event listeners for the buttons are in the buttonTemplate class. My question is, how do you call a function in the document class from a constructor class? Here is my simplified code below
DOCUMENT CLASS
Code:
package {
import flash.display.MovieClip;

here is the scenario we ran across while working on our Flash AS3 project today.
/main/root.fla
/main/root.as
/main/sub1/sub.fla
[code]....
We have many sub swf's that are loaded by the main root swf. The root swf shows the art on the stage of the sub swf, and also runs some code from the sub swf's document class. However, we noticed the constructor was not getting called on the second sub swf if the document class is the same name- even if they are in different folders. Note that we publish our swf files to a separate directory (with the same structure as above) so it is easily copied to the web server.
-root.swf loads sub1/sub.swf
-the constructor of the document class sub.as in subfolder sub1 gets called
-root.swf shows sub1/sub.swf assets with the correctly constructed sub1/sub.as document class
-user chooses to switch to sub2
[code]...
We decided to use a workaround where we basically changed the two document class .as files to be different names (e.g. renamed sub1/sub.as -> sub1/sub1.as and sub2/sub.as -> sub2/sub2.as, and updated the .fla's to point to the renamed document classes), and it works as expected. Hopefully that workaround is useful for someone.I realize most people just name every single file differently and keep everything in one folder, but when you have a sufficiently complicated project, things like this come up.

I need to pass a struct and a string in a web service. I am using a WebService components to do so.upon my search, there is no struct type in actionscript and so I used a class for that one.
public class UserInfo{
public var name:String;
public var dateAdded:Date;
}
and I'm filling it up so that I can pass it on the web service like this:
var newUser:UserInfo = new UserInfo();
newUser.name = "myName";
newUser.birthdate = new Date();
webServComponentId.operationToCall(newUser, "password");
Upon sending this request, it prompts me an error of Error #1088.
the component that is being called by webServComponentId.operationToCall(newUser, "password"); is this:
<s:WebService id="webServComponent" wsdl="[PATH OF WSDL HERE]" >
<s:operation name="operationToCall" result="functionToCallWhenResult(event);" fault="Alert.show(event.fault.faultString)" />
</s:WebService>
Basically it is a web service via MXML. So when I call the operation, it always go to fault part and shows Error #1088

in Flash CS3 I've this DocumentClass:
package { import flash.display.MovieClip; public class DocumentClass extends MovieClip {
public function DocumentClass() { trace("document class created"); } }}
This actually works, but I want to have the possibility to re-instance the DocumentClass (because I want to restart a game and the Main class is the DocumentClass).In the first frame I have:
import flash.events.MouseEvent;
btn.addEventListener(MouseEvent.MOUSE_DOWN, restart);function restart(evt:MouseEvent){ var d = new DocumentClass();}
But this code (I simplified my situation, but the result is the same) throws an error:
Error: Error #2136: The SWF file file:///E|/Documents%20and%20Settings/Pepper/My%20Documents/FlashDeve lopment/PepperGame.swf contains invalid data at DocumentClass/restart()/frame1()
What can I do to restart my game by calling the DocumentClass point of entry? Is this possibile?

I´d like to know how could use the Timer class extended.I´m trying to pass a parameter to the constructor function, so I can use it inside the listener.
Here´s example:
[CODE]
package { import flash.utils.Timer import flash.display.DisplayObject public class ChangeColorTimer extends Timer { public static const CHANGE_COLOR:String = "changeColor"; public var obj:DisplayObject public function ChangeColorTimer(delay:Number, repeatCount:int, obj:DisplayObject ) { super(delay, repeatCount) this.obj = obj } } }
[/CODE]
That was the ChangeColorTimer that extends Timer.Now, I´d want to know how would I use ChangeColorTimer.I thought it was the same as using Timer.I´ve tried this:
[CODE]
public function changeColor(mc:MovieClip):void { var colorTransform:ColorTransform = new ColorTransform() colorTransform.color = 0xEE0000 mc.transform.colorTransform = colorTransform var changeColorTimer:ChangeColorTimer = new ChangeColorTimer(400, 1, mc) changeColorTimer.addEventListener(ChangeColorTimer.CHANGE_COLOR, setNormalColorListener) changeColorTimer.start() } private function setNormalColorListener(e:Event):void{ trace("called") }
[/CODE]
I called changeColor, but, I don´t get "called" in the output from the setNormalColorListener listener.

I have a class in my .fla's library called StatBar_object. StatBar_object is an inherited class that extends from a custom class StatBar, while StatBar extends from MovieClip.
However, StatBar's constructor has a parameter (the constructor reads "public function StatBar(target:int)"). Thus, I continually get an output of:
"ArgumentError: Error #1063: Argument count mismatch on StatBar_object(). Expected 0, got 1.
at actionscript.stat::StatBox_object()
at actionscript.modes::battle_mode()"
Is there any way to get StatBar_object's constructor to include StatBar's parameter?

I am working in Flash CS4 with AS3.
I have a TextPage.fla file that contains a dynamic text field (name: PageTitle) as an instance on the stage. In the document class (TextPage) I set the text of PageTitle according to some XML. This all works fine.
I have another fla file, SpecialTextPage.fla, and that also has the PageTitle dynamic text field on the stage.
I now try to have the SpecialTextPage document class inherit from Textpage:
public class SpecialTextPage extends TextPage
{
...
}
but I get a "1120: Access of undefined property PageTitle." error when trying to publish SpecialTextPage. The error location is given as TextPage.as
As a workaround I can just copy the whole TextPage.as file and add in the extra things I need in SpecialTextPage.as but I'd obviously prefer it if I could just extend it.
I got the feeling I am not quite understanding the relationship between flash's objects on the stage and the document class.

My listener is registering before the event is dispatched, based on my output window, however I never get the "Open Doors" trace statement to fire.

I have a custom class being constructed from my main class. In the custom class it has another custom class that is passed in as a parameter. I would like to strictly type the parameter variable but when I do, 'the type is not a compile type constant etc'.This, I understand, is because the custom class used as a parameter has not yet been constructed.It all works when I use the variable type ( * ) to type the parameter.I suspect this is a design flaw, in that I am using an incorrect design pattern.It is actually hand-me-down code, having received a large project from someone else who is not entirely familiar with oop concepts and design patterns.
I have considered using a dummy constructor for the parametered class in my main class but the passed in class also takes a custom class (itself with a parametered constructor). I am considering using ... (rest) so that the custom classes' parameters are optional.Is there any other way to control the order of construction of classes? Would the rest variables work?edit)in main.as within the constructor or another function
var parameter1:customclass2;
customclass1(parameter1);
in customclass1 constructor:

I have a FLA (say Main.FLA) document class with a child MovieClip on the stage: into the child MovieClip I load other swf files: each of the files contains its own Document Class (every swf is a somewhat independent application, say quizzes and so on).For some reason I must use the Main document class to store data (scores or so) from the child swfs loaded into the Main swf. HOW do I reference the Main class? I can't find a way.[code]and dispatch an Event this way from the loaded swf document class to the Main class:[code]Now, first of all I don't know if this could even work. Secondly, I tried to make it work by adding an event listener to my Main class but id did not work.

how to make a dynamic unfilled and filled circle. that will take input from a slider to dertermine how much of the circle is drawn. I wanted to use this for a preloader. Unlike the author I would like to use it inside of a document class. I am getting 1061: Call to a possibly undefined method createEmptyMovieClip through a reference with static type document. and 1120: Access of undefined property circ1. The second is caused from the first. How would I get this to work in my document class?
//original code
// x: circles center x, y: circles center y
// a1: first angle, a2: angle to draw to, r: radius
// dir: direction; 1 for clockwise -1 for counter clockwise

I'm trying to make a slide-show that adjusts to the width or height of the stage, and eventually, of the web browser window. I was able to load and resize a picture by writing code on the timeline, but I got the Error #1009 (Cannot access a property or method of a null object reference) when I put this slide show into another movie clip loader (which chooses between different swf pages of the website, with the purpose of keeping the swf file sizes down). By the way, my "slide-show" loads the picture fine. When I use the movie clip loader to load this "slide-show" it works too. Only when I use the Flash Player to open it, it gives me the Error 1009. I looked around on actionscript.org, and everyone seems to be recommending the folowing code (or something like it):[code]
I also ran into some information about document classes and I figure maybe I should be using document classes to make this stuff more modular and reusable. So I put my slide-show code into an .as file, importing all the flash.xxx.* classes, and put it in a package and class and constructor function... in the same directory as my swf file, and set it as the document class to a blank fla file. Then I tested it and all I got was a blank swf. This is without the Event.ADDED_TO_STAGE code. I guess I don't know how to get the document class thingy working either. So my question is, can someone tell me how I can change my slide-show code into a working document class without the Error 1009?r?[code]

I am creating a Weapon class for a game and the weapons itself will be the sub classes. The sub classes will hard code some values (such as max ammo and the weapon name).
I trying to access this declared data in the base class constructor, at the moment it's not outputting the values. Is this possible?
I've broken my Weapon class for simplicity:
ActionScript Code:
package
{
import flash.display.MovieClip;

My current workaround is creating a protected method in the base class to trace the information and calling that method in the sub class's constructor, this works fine but this doesn't seem like the most efficient technique?

URL...An untyped variable is not the same as a variable of type Object. The key difference is that untyped variables can hold the special value undefined , while a variable of type Object cannot hold that value.[code]Why is assignment to undefined allowed for obj? (not a big issue since it still prints as null)If we compare null with undefined the result true (even if null stored in an Object). What is the point of making a difference between null and undefined if they are equal?
