I can't use a "for in " loop to enumerate public properties of a custom class. So I have a class "ClassA" , which has some public properties. if I try :
PHP Code:
trace(classInstace.hasOwnProperty('property1'));// true
trace(classInstace.property1) // traces the property correctly
trace(classInstance.propertyIsEnumerable('property1')); // traces false ????
In order to send a POST request I need to enumerate all properties of a given object. This object may or may not be dynamic. I'm looking for the most elegant solution. This is what I've got so far:

In AS2 we can not add methods n properties to built-in classes in the way we do in AS1. Like we would -say- write the custom "isNatural" method on the "Math" class as follows : * The following code is valid in AS1 but not in AS2

As the "Math class" is static internally. We know why we can not add custom methods n properties to every class, as the way we do in AS1. Later I came up with senocular' s very nice tutorial on OOP in AS2. And now i know how we can do it in AS2 style in an efficient n organised way. But i have a problem with the following code. It should not work ! but it does... * Following code is valid for both in AS1 and AS2.

So I have a movie clip associated with an external class in the linkage dialog. I put that movie clip on the stage. I have another external class that contains some code (not for the movie clip but for the stage). When I access the custom properties of the class in the actual flash file (not the external code) everything works fine.For example.myMovieClip.explodeTheCode = true;works in the main movie. However, it doesn't work in the external flash file when I have a reference to that movie clip.myRefToCustomMovieclip.explodeTheCode = true fails!It throws an error. In java, I'd just import the custom class the movie clip is linked to and then I can call all the extra custom methods on the movie clip in the external class I want. However, this does nothing. I still can't access any properties.So my question is, how do I access the custom features of a movie clip (that is linked to a custom class) from an external code file. It works in the movie, but not in the external source code.
View 0 RepliesI am new to AS3, as well as Flash in general, so forgive me if this seems highly elementary. All I am trying to do is create a custom class that extends the MovieClip class and contains a custom property of "marker".

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

This is my first time working with a class attached to a movieclip that is nested inside a class attached to a movie clip.I've tested all the properties and methods of PTListItem.as and they work properly but when I try to call them on the list item through PTListTop.as it returns undefined.The end goal is to dynamically load a checklist via a txt file.
View 1 RepliesThrough searching the various forums I have found that Loaders are not dynamic and hence you can not apply custom properties to each instance of them. I miss the old way (as2 way of attachingMovieClip) that you load dynamic content, at least you can apply custom properties, and you can always reference them for each object.

I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.
I am very new to AS3, and I'm confused about how things that would have been simple in AS2 are so complex and tricky now. For example, I want to create a bunch TextField objects that, for some reason, rise up every frame (as in : object.y-=1; ).However, I also need each TextField to reference the TextField that was created just before it.
I tried creating a variable that would hold such a reference : ThisTextField.Ref=LastTextField; but - this returns an "Access of possibly undefined property..." error. It seems I can only have custom properties on mere Objects ! This is annoying because an Object doesn't seem to accept event listeners (remember, I need them to do something every frame). Is there a way to simply set custom properties on my TextFields, without having to use custom packages ? Or is there a way to use event listeners on Objects ? I've read something about strict mode which could allow setting properties on other objects - what are the risks of turning it off ?
I have been stuck on this problem for a while, and wonder if anyone knows the answer. It is concerning accessing some properties of a custom component. I marked the problem with the keyword [PROBLEM] in the following snippets of code.

Is it possible to dynamically name properties on a custom object ?
something like:
Code:

o.[s] = '1234'; // 1084: Syntax error: expecting identifier before leftbracket.

I have a class, call it MyClass, and there are several variables that I need to be able to access each instance of from within the class.So for instance, I need the object myObject1, a member of MyClass, to store the variable myNumber.From the main timeline, if I trace myObject1.myNumber, I get whatever number I've stored.
However, I need to check the numbers against another parameter, so I need to be able to test if myObject.myNumber == myOtherNumber. But from within the class, if I trace this.myNumber or myNumber I get null.What is the proper syntax for accessing a variable within a class?
I have an mc called sunny. In the properties panel I export her for actionscript. I put Sunny in the main class and Drag in the base class. The reason for this is that I want her to be draggable. I can't use Drag in the main class as another object is using that name. The Drag.as has the drag functionality. Why can't I drag her. I already have a solution - I wrote a specific class for her and extended the Drag class. However, if I have 10 mcs I'm not going to write specific classes for all of them. Summing up: Using the base class Drag in properties panel - why isn't she draggable?

View 1 RepliesI'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component.
I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class:
<s:Label color="{data.color}" text="{data.label}"/>
Where data.color would be set whenever the user gives an answer to a question.
Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example).
