How do I create a class that extends the String class?
Lets say I've created an 'exString' class that extends String.
In my project file I do the following
Code:
var test:exString = new exString();
test = "Hello World";
text.someExStringFunction();
I get a type mismatch in my "Hello World" assignment because Flash sees it as a String and not as an exString.
i came across this problem and i have no clue why it's happening. basically, consider 2 nested movieclips on the stage, something like stage -> main -> filler. both movieclips have instance names (main and filler).
[Code].....
this throws an error 1119: Access of possibly undefined property filler through a reference with static type A. can anyone give me a hint on that, as it works with class A, but not B extending A? i understand it was meant to work?
I am trying to create an AS 3 class that extends DopDownList (Spark) but behaves differently than your classic DropDownList. The difference is that when a user selects an item from the list, he cannot just click on the item. The user must "mouse-down" on the item, drag it over to the right, then "mouse-up" and then the item will be selected. The purpose of this is to act like a safety feature so the user doesn't select the wrong item. I am new to AS 3 and I am stuck on how to do this. I've been playing around with different events and methods for the last few days, but to no avail. If anyone could give me an idea on how to implement.
View 0 RepliesI'm having an issue using a class I've created as the base class for library symbols: I've created a class AvSkin which will act as the display for an instance of AvChild. It looks like this:
package avian.environment.skins
{
import flash.display.DisplayObject;[code]....
Is there a way around this? I don't want to do either of the following:
Make AvSkin extend MovieClip.
Create a class for my library symbol that extends AvSkin.
googled it and hardly found any answer(seriously)need a quick solution for this:- How to create object from class that extends MovieClipSay i have a class name MC

I'm beginning to learn AS3. I'm getting the following error[code]...
View 5 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 want to be able to use and change the value of this custom property on the timeline for an instance of this class and have it behave just like any other (Ex: this.x ==> this.marker).

If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass:
public class MyMainClass extends MovieClip
fla2.fla has a document class of MySubClass:
public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.
I'm not really asking how. What I'm asking is, is it possible? And I ask because I thought it was not - certainly it didn't work in AS2 - and yet that's what I appear to have done. Am I going crazy? Structure: A SWF (#1) with a class NewActivity that extends class AActivity. Another SWF (#2) with a shared library of code in it, including AActivity. A third SWF (#3) which loads the library followed by SWF#1. Here's what happened: I didn't expect AActivity to be able to be shared. I mean, it should be compiled no matter what in SWF#1, as SWF#1 includes a class that extends AActivity. I had added some properties to the AActivity class, ran the project, and when SWF#3 tried to set those properties I was told they couldn't be applied. "Of course", I said, "I need to recompile SWF#1, because the code is now out of date. The version of the class there doesn't include these new properties.".
However, that didn't work. I got the same problem. Maybe, I thought, there's a definition conflict between SWF#1 and the library, so I removed the AActivity class from the shared library in SWF#2 for the time being. Only SWF#1 uses it, and it should already be compiled into SWF#1 as, like I said, it is extended by another class there. But when I ran the project, I was then told that the AActivity class could not be found at all! Looking at SWF#1 in a decompiler, there is in fact no mention of AActivity (I had up to this point assumed it was implied). So this left just one option: I needed to recompile the library in the first place, not SWF#1. I added AActivity back to the library, recompiled, and it worked.
To check I wasn't going crazy: I added a test property to the AActivity class and recompiled the library. The containing project - SWF#3 - then set this property on SWF#1, which had NOT been recompiled, and then read it back out. No errors. I should point out that the getting/setting of this property is done through an IActivity interface - AActivity is not being accidentally compiled into the main project (SWF#3), and the decompiler indicates this also. Am I going nuts? I really didn't think having a runtime shared super class was possible in any way. If it is, that opens up a whole new world of awesome, even though I've created this project on the basis of that being impossible.
I'm trying to load a RSL library into a flash animation developed with Flash CS5 IDE, that extends a custom class and implements an interface. I have reduced the problem to the simplest setup and find that I can have my main class extend another class or implement an interface, but not do both at the same time if I want to load an RSL.I have a very simple class to extend:
import flash.display.Sprite;
public class MySprite extends Sprite
{[ code]...........
but if I want both I get the VerifyError: Error #1014 with MySprite not found and ReferenceError: Error #1065.
If I can create dynamic variables on a MovieClip.. why would I not be able to create dynamic variables on a class that extends MovieClip?

In AS3, I'm trying to check whether an object is an instance of, or extends a particular class. Using something like if (object is ClassName) works fine if the object is an instance of ClassName but not if it's an instance of a class that extends ClassName.
Pseudo-code example:
class Foo {}
class Bar extends Foo {}
var object = new Bar();

I'm new to Flash AS3. I started making a game and I am a bit confused. Let's assume that I want to create a game that has multiple levels/modes, how can I do this in an object orientated way?

I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

I have a class CoverPoint extends Pointwith some extra function.except for that ther is no difference. I would like to use the functions of Point with a return value of Point, to calculate those CoverPoints.Can i turn the return value into CoverPoint (since all the vars are the same, there shouldn't be a problem with that, right?), so that it can be stored in my var cP:CoverPoint;
View 2 RepliesIs it possible to create an object from a class with a dynamic name? I have the name of the class in a string, but I want to create an instance of that class.

Okay, actually it extends DisplayObjectContainer, but anyway...I want to be able to use this class in several different applications, even applying it to library items. It also overrides several of DisplayObject's methods, which is very important.Basically, it works (or will work) just fine extending DisplayObjectContainer, but how do I allow other classes that extend DisplayObjectContainer to use the features of my new class. For instance, here is how the class looks now:
Code:
public class DockContainer extends DisplayObjectContainer
{ ... }

I've been playing around with custom classes. My objective was to create a custom class (Testing) that would create a box when an instance of the class is created. I've tried three different approaches, however only (3) seems to be showing up. I'm just curious why (1) or (2) doesn't work?
Also is there a better approach than (3)? Since at the moment it's been created on _root. I hope the box can only be accessible through the instance. Since I'd like to incorporate the whole idea of public, private, encapsulation, etc.

I'm trying to have a class that is an Object to hold details about the movieclip that it is attached to.
[Code]....
and two others of this nature. I didn't think you had to declare the 'key' of the object as a variable before setting it in the Object. So my guess is that it is angry about the class itself, somehow. (syntax or the like)
Is there any way to get the name of the MovieClip that a class extends?Lets say I have an MC on stage called boxMC exported for AS using a class box which extends MovieClip.If I trace (this) within my class I will get the name of the class, if I trace (parent) I will get the name of the main MovieClip that boxMC sits within. So how can I target boxMC?Basically I want to be able to return the name of the MovieClip that the class is extending

I'm working on a Flash Lite 3.0 application using AS2 and I've created a class that extends MovieClip. The problem is that I'd like to dynamically add Child Movieclips using the addChild method... but it doesn't work, it gives me the following compiler error: "There is no method with the name 'addChild'". But I can call other MovieClip specific methods such as this.getNextHighestDepth()

class com.sck.DragList extends MovieClip {

I am having trouble using inheritance, I made a class called newchars_2 that extends my class newchars and i get this error (newchars class extends movieclip):

newchars_2.as:
package {
public class newchars_2 extends newchars {
private var obj_no = 3;
public function newchars_2() {

And when I want to import this class do I import both the class's or just newchars_2 because it has all the functions inherited?
