ActionScript 3.0 :: Extends Classes At Run Time?
Dec 29, 2010Is it possible to extend classes at run time, it's like a dynamically extend classes.
I don't know if this possible in AS3.
Is it possible to extend classes at run time, it's like a dynamically extend classes.
I don't know if this possible in AS3.
I have a class name BigClass and some other classes that extends BigClass named SmallClass1 SmallClass2 etc.
I have an instance called bila of SmallClass1 (or it may be of SmallClass2 etc). I'ld like to duplicate this instance - like bila2 and bila to refer to same thing, so bila can follow his normal course of actionscript3(change reference) and bila2 to do some movement (the class extends movieclip).
[Code]...
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?
So I posted a question earlier similar to this, but this is a totally different thing and in CS3, not CS4--and on a different machine. I have a video player .fla that imports VideoScaleMode and VideoEvent, but when I test the movie I get compile errors saying the definitions can't be found. These are in the fl.video package and that's how I'm importing them:
import fl.video.VideoScaleMode;
import fl.video.VideoEvent;
But for some reason they aren't found--or at least that is the error that is thrown. The same exact code in an .fla that I previously developed works perfectly, right next to the problem .fla at the same time in the IDE, so why in the world wouldn't it work in this one? In fact, even if I create a brand new AS3 flash document and paste the code above onto the timeline and test it, I get the 'definition not found' errors. But if I click over to my old .fla in the IDE and test it, no problem. And the AS3 settings (classpaths) are identical in these files.
Is there any way to auto-import as3 classes (internal/intrinsic Flash Player classes at least) using Emacs ?
Looked for as3-mode and actionscript-mode but nothing working was found. as3-mode can import class if it is opened in buffer (but not *.mxml files)
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?
I have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).

I was wondering when you guys extends EventDispatcher in your class. It seems to me that as long as we have import event package, we can dispatchEvent without problems....I saw sometime people extends EventDispatcher in their clas

ActionScript Code:
function checkInheritance(TargetClass:Class, CheckClass:Class):Boolean
{
// return TargetClass implements CheckClass;
}
in human.as:
class human extends MovieClip {
function onEnterFrame() {
_x += 10;
}
[code]....
in my fla:
Object.registerClass(skin1, human);
_root.attachMovie("skin1", "User1", 1);
so i have an attached movieclip on _root now, i can see it but the onEnterFrame function doesn't work. Why??
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
{ ... }

View 2 RepliesLike I understand that if you're assigning something within a class it would have to involve what's extended to this class.So if a class extends MovieClip, would you only Set properties that involve the MovieClip object?Adversely, with Getter functions you could be retrieving anything from XML to volume. So that can't have anything to do with what that class is extending towards right?Is that how the extends relationship works with Get (return) and Set (value) functions?
View 9 RepliesI'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)
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 1 RepliesThis is class A
Code:
class A extends MovieClip
{
public function A()
{
[Code]....
But I don't know... why extends MovieClip in this case? Because what I'm trying to do is a movieClip at the end...
In my code, I dynamically attach objects that extend MovieClip similar to the following code:
myMovieClipObject.attachMovie("ObjectA", "ObjectB"+ i,200+i);
ObjectA is an object in the library. Its linkage is to an AS 2.0 Class, we'll call it myClass defined as follows:
class myClass extends MovieClip {
var myProperty:String = "Some Value";
};
Later in my code, I can do all sorts of things to, say, ObjectB10, but the following is undefined: ObjectB10.myProperty;
So I have a class that extends sprite. When I call an instance of my thumbnail object, I apparently can't use typical transforms on it by accessing .x and .y properties. These are not inherited from the superclass? Do I need to tell it to inherit these traits?

I am writing a class button that extends Sprite. I use graphic fill to draw button and then use addEventListener to add Tween to MouseOver event. Problem is:
1) If I use MOUSE_OVER event, the tween became sometimes corrupt when Mouse is INSIDE the button.
2)If I use ROLL_Over event, the tween became sometimes corrupt when Mouse is NEAR the button BUT ok WHEN mouse is far enough.
I'm trying to import a class from a class that is located in another folder. How do you move up a directory? Using./ or ../ doesn't seem to work. Essentially I want to access a TweenLite Class but not from the document class. My class is at com/myName and the class I want to access is at com/TweenLite. import ../TweenLite doesn't work... I realize I could just copy and paste the entire Tweenlite folder again, but there's got to be a less duplicative way of doing this..
View 2 Repliesinheritance and building classes from other classes.
I have 3 classes:
gfxRoomText - changeable colour
gfxRomInter - changeable colour - interactive
gfxRoomImg - interactive - only image / no colour
The first two incorporate the same text field and functions to change colour. The second and third incorporate another class to interactive with. What is the best way of creating these classes using inheritance and how?
I just want do dispatch a simple event.I have this in a function in a class ShieldCreator extends EnemyShip:
PHP Code:dispatchEvent(new Event("ShieldCreatorDied",true));
and in a class ShieldShip extends EnemyShip:

But the function is not executed when supposed to. whats going on? btw. this is all i have done, i dont know if you have to do anything else, and i can't find any tutorials, that explain the basics ( they're all about custom events).
