extending Object on a custom class that would normally be unextended?
package qnx.notificationManager
{
public class Notification extends Object

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.
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();

I have written a Class for skinning the UI. The Class works by taking a movie clip name from the stage passed to it and create the skin for it.So I create an Object from the class such as this:
Code:
var CBox:UI = new UI();
Now what I wanted to do is reference a movie clip from the stage to this CBox variable, so when a call the Class methods it will know which movie clip to work on! Since currently I have to do this:
Code:
CBox.Skinning(content_mc, "content", 100, 200);
or
CBox.Over(content_mc);
As you can see Im passing the movie clip, content_mc, everytime. I just want to avoid this by creating a reference.
I created one "MyObject" class which is extended from Movieclip. In my flash stage, i have one movieclip and the name is "myObj". I dont use linkage. How can i convert movieclip to MyObject instance.i tried the below one, i got errorar str = MyObject(mc).name;The error is
TypeError: Error #1034: Type Coercion failed: cannot convert ash.display::MovieClip@2b6baf99 to MyObject. at Obj_fla::MainTimeline/frame1()
For the game I am making, I'm using a self-made sprite managing system.I've got three classes: SpritesManager, SpriteGroup extends Movieclip and Sprite extends Movieclip.The idea is: SpritesManager is holding an object: "mainSprites", SpritesManager also hasa method "newGroup", wich creates a new SpriteGroup in mainSprites.In this way I want to make a system for creating and managing some sort of Movieclip-tree.For example:mainSprites.enemies.badEnemyThe method newGroup in SpritesManager has a param "name" wich is the name of the SpriteGroup to create.Here's where I'm stuck: how do I create a new SpriteGroup referenced to as "name" in mainSprites?

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.
I am creating an object pool to cache some recyclable objects in memory at the outset of my application in order to avoid (as much as possible) the performance issues caused by GC running; if possible I'd like to minimize the memory my object pool reserves, so I'm attempting to pool generic forms of the objects (with no methods) and then casting the generic variants to more specific and complex object types which extend the generic form when I actually want them on the stage.
The trouble is that to do this requires the generic variant class to import/extend MovieClip (because the more complicated objects are themselves MovieClips and make use of DisplayObject methods)-- does simply importing and/or extending a class add to the memory an object takes up when instantiated even if it never uses methods from the inherited class? It makes sense that it would, and some light profiling seems to suggest that it does, but I'm not 100% certain. About how large should an 'empty' MovieClip instance be in bytes?
I've created a custom class to represent a monster in a game. The class definition has "public class Monster extends Object". I'd like to know if there's a way to initialize the object using object literal notation. For example, this works ok:
[Code]...
I get this error: "Implicit coercion of a value with static type Object to a possibly unrelated type Monster." Is there a way to do this? I'd rather NOT have to call the Monster's class initializer each time, because in the actual code there are a lot more variables in the monster class than just those three, and it's kinda unwieldy to pass a dozen long strings into the new() function.
I have created some (TextInput, ComboBox, CheckBox) Component instances (created as a public objects) in a Document class and added them to the stage.
Now I have created a custom class for a movieclip in library and instantiated it in the document class (also a public instance).
I need to access the component instances in the custom class. How to do this ?
Also, Is it a good practice to use ENTER_FRAME event frequently ? because if I can't access the above components instances in the custom class then I will be left with no choice but to use ENTER_FRAME event in the document class every time I need to change some value in the components...
I'm currently trying to add the resulting XML (xmlResult) to a textbox that is on the stage. I did try using MovieClip(root).[instancename].text = ..... however it didn't work - null object reference?

View 3 RepliesI 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.

new to ActionScript 3 and while I'm trying to write as "clean" code as possible (creating various custom classes instead of everything in the document class for example), sometimes I stumble upon behaviors that would not arise if I had put everything in the same place.I have a project which involves fireworks which is working fine, but I'd like to add a smoke trail to the rockets (a custom class rocket object) and so far I can't get it done.
So I will ask my question first: what methodology do you use in general when you want to make a custom class object leave a trail of particles behind it? Do you include the trail generation in the class? in a separate class? on the document class?what I've been doing (and what I feel is the "cleanest" and most reusable way to do it) is to put the trail generation in the custom class rocket object. This object is just composed of some graphics and the function that generates the particles(which are another custom class).The actual handling of the firing and the movement of the rocket is done by the document class.So the problem I'm having is that when I generate a particle on a frame, if I add it to the rocket object, it follows it (local coordinates), and if I add it to the stage then I can't remove it from within the rocket object...
I am using Flex 4 and for whatever reason I cannot get the following code to work which happens inside of a ListEvent handler for a dataGrid:
_tempRule = DataGrid(event.currentTarget).selectedItem as Rule;
Rule is a custom class, and the above code always returns null. The dataprovider for the datagrid is an ArrayCollection. If I try to wrap the above code to make it like the following:
DataGrid(event.currentTarget).selectedItem as Rule
I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@e15a971 to com.mycompany.arcc.business.Rule
Now I know I have done this before with native Flex classes like Button, etc, but it my case it will not work. Here is the Rule class:
package com.mycompaany.arcc.business {
import flash.utils.describeType;
import mx.collections.ArrayCollection;

I have the following as code in a separate file placed in the root folder of the swf file. The as file is the class for a MovieClip in the library.When i manually place the library symbol on the stage, the MC works fine and draws the square with the nodes. However, when I try to create a copy using ' new sqMC();' code, I get an error.
Code:
package {
import flash.events.MouseEvent;
import flash.events.Event;
import flash.geom.Point;

I'm extending the Flex 3 panel component. I need to figure out the width of the title's text. Because, title is a private variable in panel, I can't access it via title.width.I know the font, fontsize (14), and length of the title (which will vary). Knowing this info is there a way to calculate how many pixels wide the title is?
View 1 RepliesI am programming a web based application with Actionscript 2.0 classes for flash 8, and I want to save user data using the local shared object.As the data is potentially rather complex I would prefer to store it in an instance of a custom class that I then stick in an array property of the local shared object data property.However, when I try to do this, if I retrieve the stored object it seems to have lost all its instance methods. If I do a for in on it, I can see the private properties to which I have assigned my data, but as they are private I cannot retrieve them.how I can store an instance of a custom class in a local shared object without it being corrupted in this way?
View 4 RepliesI 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

View 6 RepliesI 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?)

Is this possible? Extending From the Document Class?
Because I have this as code and can't get a trace[code]...
All I can find online are examples of instanciation, not inheritance when connecting/accessing the document root:
var mySubTest:TheSubTest = new TheSubTest();
Is extending from a document root impossible? I can create a new instance, but branching out seems like a dead end.
I'm having an issue extending a class in the JWPlayer API, but I think it's probably more of an issue of the way I'm extending the class in AS3 rather than the class itself. Here is the code:
Code:
package {
import com.longtailvideo.jwplayer.events.*;
import com.longtailvideo.jwplayer.parsers.*;
import com.longtailvideo.jwplayer.utils.*;
[code].....
All three of the final functions do not return values even though I have event listeners only calling those values one Event.COMPLETE (of the loaded SWF that contains this script).
