ActionScript 3.0 :: Custom Class Extending MovieClip - Constructor/assignment?

Jul 10, 2009

I've got a simple class:
 
package somepackage
{
import flash.display.MovieClip;

public class NewMc extends MovieClip{  public var myVar:String = "something";}}
 
And there is a question now: how can I assign a "real" MovieClip object to my created-class object?
I mean: var realMc:MovieClip = new MovieClip();

ActionScript 3.0 :: Extending The Custom Class?

Feb 12, 2012

I made the transition to AS3 two years ago, but I still carry with me old AS2 habits. Could someone please help me understand how I extend a custom class correctly. I have the bad habit of putting most of my code in one .as file (the Document class), but I use a few custom classes now and then. What I'm tring to figure out is how I would extend a class of this type:
 
public class ClipDragger {
private var _clip:MovieClip;
public function ClipDragger(clip:MovieClip) {
_clip = clip;

[code]....
 
For example I would like to add a MOUSE_MOVE listener, and also add actions to the drag function.

Actionscript 3 :: Automate Property Assignment To New Instance From Arguments In Constructor

Apr 8, 2010

I like finding out about tricky new ways to do things. Let's say you've got a class with a property that gets set to the value of an argument in the constructor, like so:[code]That's not exactly a hassle. But imagine you've got... I don't know, five properties. Ten properties, maybe. Rather then writing out each individual assignment, line by line, isn't there a way to loop through the constructor's arguments and set the value of each corresponding property on the new instance accordingly? I don't think that the ...rest or arguments objects will work, since they only keep an enumerated list of the arguments, not the argument names - I'm thinking something like this would be better:[code]

ActionScript 3.0 :: Passing Arguments To A Custom MC Class Constructor?

Oct 30, 2011

I'm having trouble with the constructor for a custom Class tied to a library MovieClip.
 
Say I have a MovieClip in my library named Circle, which is tied to the class com.shapes.Circle . I want the Circle class contstructor to take 2 arguments, xScale and yScale:
 
public function Circle(xScale:Number, yScale:Number) { }
 
However, if I try to call that from in code, for example Circle ball = new Circle(3.14,2.0); , I always get an "Incorrect number of arguments. Expected 0" error.
 
Is it possible to have a custom class tied to a MovieClip that can take arguments, or does Flash not allow this? I'd asked about this before and thought I figured it out, but from looking at it now I apparently hadn't figured it out and had resorted to a sloppy workaround; I'm hoping to fix it now.

ActionScript 2.0 :: Custom Class Instance Doesn't Recognize Own Constructor

Aug 18, 2011

I'm having a problem with customized Actionscript objects not recognizing thier own constructor. This is the pertinant part of my script:

ActionScript Code:
//File: Line.as
class Line extends Object{
public function Line(args){

[Code].....

Clearly, the variable "testLine", is one of my custom "Line" objects. Clearly, it has been made with the "Line" constructor. So why won't flash acknowledge this?

ActionScript 2.0 :: Define A Custom Class To Be An AsBroadcaster In The Classes Constructor?

Feb 22, 2007

Can I define a custom class to be an AsBroadcaster in the classes constructor?

Code:

class myClass{
function myClass(){
AsBroadcaster.initialize(this);
}
}

And if so will that give me the ability to addListeners to an instance of that class?

The reason I want this approach is because I want to broadcast events from inside one of the custom classes methods and I want a textField on the stage to be listening for that broadcast message.

ActionScript 1/2 :: Extending The MovieClip Class?

Mar 3, 2010

I want to add a property to the MovieClip class. I just have a bunch of MovieClips that are placed on the stage by reading an XML file and creating lots of clips according to the information in them. Now, I need to know which MovieClips were created below previous clips, and I figure that the easiest way to do so would be by extending the MovieClip class and add an order property.I have some problems though: I don't know how to set or get this order property within the main clip, I don't know how to place this clip within my movie, and I don't know how to create them dynamically (do I just do something like var myNewObjectOfExtendedClass : myExtendedClassName = new myExtendedClassName?)
 
This is the code I have on my extended class, called Expando.as:

ActionScript 2.0 :: Extending A Class From MovieClip?

Apr 18, 2006

extending a class from MovieClip? I could just make a movieclip variable in the class to make it simpler. I heard if you extend from Movieclip it makes it feel like its dynamic because you have frames (gotoAndStop, etc). However, it allows me to have direct access to variables (or this.) instead of somemc., and I believe thats faster because 1) smaller name variable lookup, 2) no get function call.

ActionScript 2.0 :: Why Is Extending MovieClip Class Different

Jul 9, 2007

I've been going through the OOP AS 2.0 tutorial here on Kirupa, and I was curious WHY this code is in a class which extends the MovieClip class and is used to affect a linkage item in the library:

Code:
// init method for arguments which in other normal
// circumstances (non-MovieClip classes) would be
// given to the constructor. Not an option with MovieClips

[code].....

Is there something undocumented about why I wouldn't pass those parameters in when instantiating a new instance of the class in question? What is different about extending the MovieClip class?

ActionScript 2.0 :: How To Implement Interface To Class Extending MovieClip

Aug 5, 2006

Is there any way of extending a class which is extending the movieClip class? Or generally a way to add extra methods to an allready existing class without having to add them in the actual class declaration. I was thinking of using Interfaces but how can I implement an Interface to a class which is extending a movieclip?

Code:
import interfaceName
class className implements interfaceName{
//stuff
}
But where do I put the code which extends the MovieClip?

Code:
class className extends MovieClip{

ActionScript 3.0 :: MovieClip (Controlled By Extending Class) On Stage Reference

Jun 2, 2011

I'm currently working on a AS3.0 project in Flash. I have a main movie clip in flash on the stage. This mc contains 3 frames. They represent the pages in my application. In each of those frames are a lot of nested MCs. Such as menu buttons, display content for the MC buttons, etc. Everything is controlled by a class extending from MovieClip. When I run the application and press the green button on the second frame in a nested MC of the main Movie Clip on the stage. The event must jump to the 3th frame in that main MovieClip.

Here's the problem
If I immediately press the green button, everything works great.
But this does not happen when I press a different menu button first.

Now the code works fine but when i write my own (sealed/fixed) Box Class that surely Extends MOVIE-CLIP, statement-2 gives error , i know the Box Class is not dynamic but the Movie-Clip is Dynamic. Now what i understand that Movie-Clip Class being dynamic becomes fixed/sealed when it is extended by any Fixed/sealed Class???

Flash :: Add Parameters In The Constructor Of A Class A, Subclassing Movieclip, Present On Stage At Design Time

There is a library component represented by Class A. But constructor of this class requires some parameters. When the component needs to be added dynamically, it's fine because of code :

var abc:A = new A(param1,param2)

But what if my movieclip is already present on the stage. I notice it gives out error, that the parameters are null.

Is their any way to insert constructor parameters for movieclips already on stage.

Actionscript 3 :: Can A Document Class Extend Another Custom Class That Extends MovieClip?

Aug 16, 2011

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.

Flex :: Extending DataGridColumn For Custom Sorting Function

Aug 25, 2009

I extended the DataGridColumn because I wanted to include a custom itemToLabel function (to be able to show nested data in the DataGrid. See this question.

Anyways, it also needs a custom sorting function. So I have written the sorting function like so:

private function mySortCompareFunction(obj1:Object, obj2:Object):int{
var currentData1:Object = obj1;
var currentData2:Object = obj2;

[Code].....

Whenever I try to sort the column, I get the error "Error: Find criteria must contain at least one sort field value."

When I debug and step through each step, I see that the first few times, the function is being called correctly, but towards the end, this error occurs.

Actionscript 3 :: Unexpected Variable Assignment Inside Static Class Method

In the following code (thoroughly debugged) the first case (1) in the switch is met and a new instance of BannerSingle is assigned to retVal (the return value). Unfortunately, while the second case (2) is never met, the assignment therein to retVal takes place and I can't compile. When I comment out the assignment to retVal for "case 2:" everything works fine.

I've tried using an if/else instead and I still get the same odd behavior. Also tried a number of solutions involving separate variables, etc.

Flex :: Custom Preloader - Extending Sprite To Load Animation SWF

I am following this page to create a custom preloader extending Sprite to load an animation SWF, but it is not working (the animation SWF is not displaying): [URL]. I know the Animation.swf file is okay, because if I load it into the main app it displays and runs. The preloader works if an image is loaded by the preloader instead of the animation SWF.
test.mxml (main app)

BTW, I typically have many more lines of ComboBox in the app to force the preloader to display, but limiting number of lines here.
