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 RepliesI'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'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)
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 have extended an mxml component with an actionscript class. I'm trying to access a component in the mxml file using the id (in order to add an event listener) but I cant seem to do it.
I get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I followed the example from a previous question and I am loading an external swf using a loader and inside the loader event handler I am trying to cast the loader.content as my custom class PanelReferenceClip which extends MovieClip
When I publish I receive a this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Just to make sure and test that the swf location was correct and the swf was actually being loaded, I changed the type of the content to as MovieClip and it worked fine.
EDIT: I also wanted to add that these swfs are being stored locally and not being pulled across the internet, multiple networks or servers.
I am not sure if I did something quirky in my class so I am providing the source to my custom class PanelReferenceClip
package com.components

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?
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?

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.
If I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()
Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:
stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)

I have question regarding removing instantiated objects. Let's say i have a main class in which i instantiate a custom video player (or whatever) class:
[Code]...
From my experience, if i don't destroy for example event listeners from my VideoPlayer class and just remove VideoPlayer class the way described they still get fired with null exception messages etc. This is something that's bugging me for a while so i would really like to know what's best thing to do here?
When I use MouseEvent.MOUSE_OUT the target is [object MovieClip], but when I use MouseEvent.ROLL_OUT I get [object Bildspel] - and Bildspel is my class. The thing is that when I use ROLL_OUT I'm not able to delete the targets ENTER_FRAME event.

I found myself loading a new XML file every day and so decided to create a small class that will load the xml file and return it.The class is loading the file but when i try to return it to a new xml object in the document class it doesnt load it.I think that it's something to with the return being in a nested function but i tried a few ways and non seems to work.

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.

class Foo {}
class Bar extends Foo {}
var object = new Bar();

I have created a class, call it Class1, that has various objects drawn on the stage (drawn in the IDE). It also has a function, called setColour, for changing the colour of those objects. The function works fine if I call it from within Class1.
Now I have another class, call it testClass1, that imports Class1 and calls the setColour function. First of all, none of the stage objects from Class1 are visible. Secondly, when setColour tries to modify the colour of an object, I get the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
This is the code for testClass1:
ActionScript Code:
package
{
import flash.display.*;

So, what is the problem? Is it possible to change objects that are drawn on the stage of an imported class?

View 3 RepliesThe following is that long only because I gave examples of what I want to know, not because it is complex .I have three basic questions regarding AS 3.0 classes.
1. How can I make a class object interact with an object on stage?
For example, when I have a square (mc_Square) with class "square" attached to it and I want it to trace "Colliding!" and print the X and Y of the mc_Box on contact with an on-stage *hollow* box (mc_Box) that has no class attached to it.how to do it vice-versa would also be awesome .
2. How can I make a class object interact with the same class object? For example, when I have two squares (mc_Square) that both have the class "square" attached to it and when they collide, it prints the X and Y of both of them.
3. How can I make a class object interact with a different class object?
For example, when I have two squares mc_Square1 with class "square1 (that also has a variable Primary=true written in it)" and a mc_Square2 with class "square2"; When they collide, the one with Primary=true would be removed and it's X,Y position traced.
