ActionScript 3 :: Extending MainClass - MovieClip Versus Sprite
Mar 29, 2012
What more can be done if I extend MainClass with MovieClip rather than Sprite. I know that MovieClip extends Sprite and it has Timeline defined under it. But still how it will be usable to me by MovieClip ?
package {
import flash.display.Sprite;
import flash.text.TextField;
import flash.text.TextFormat;
import flash.display.MovieClip;
import flash.text.TextFieldType;
[Code] .....
How to use Timeline if I replace Sprite by MovieClip ?

I have a program that dynamically draws a polygon wherever the user clicks on the screen. (using lineto, moveto) However this polygon is always behind the other symbol objects on the screen even though its added last in the childlist. Is there an issue with depth when drawing symbols vs. drawing with lines? How can I ensure my dynamic object will display in front?

I created a class, extended the sprite class, and now in the constructor I am trying to set the Sprite's width and height properties which are inherited from the DisplayObject. However, after I set this.width and this.height, and print the values, I get 0 for both.
What the heck is going on? When I view the livedocs I see that DisplayObject has width and height listed as public properties. I have been able to instantiate a Sprite directly, and set the width and height after it's been instantiated, so I don't get it.

import flash.display.*;

I can't quite wrap my head around the differences. In what situations would I choose one over another?Specifically, I'm creating a sort of View component (in a very hack-y sort of way, I'm sure) that can redraw the interface with the same visual components (some of which change slightly depending on the mode) in 3 different modes: Normal, Small, or Fullscreen. The trick here is that both the Normal and Small modes can *also* go fullscreen as well, though you'll never be able to switch between Normal and Small in the same session (it's determined up-front).

I also have some MovieClips which have their own class and functions.
I am trying to call a function from my main class which is part of a MovieClip.
This MovieClip is on stage. Example [code]...

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.
CustomPreloaders.SparkAnimationProgressBar.as
package customPreloaders {
import flash.display.;
import flash.events.;
import flash.net.;
import flash.utils.;

When I use the classpaths to my packages and use a empty package name it works..
classpath: .comcc
.fla
Code:
var scene:Mainclass = new Mainclass(this);
addChild(scene);
Mainclass
Code:
package{
// imports
public class Mainclass extends Sprite{
// vars
public function Mainclass(scope){

I tried to put a classpath to reflect my /fla location, still no success.

I'm using AS2, and trying to use AS2's packages for the first time, so I can organize my .as files properly. I'm running into some problems though I've got some classes that extend MovieClip, and I've put the class names in the Linkage>Class fields. When I publish, though, I get the error: The class or interface 'ClassName' could not be loaded. anyone know what I'm doing wrong? I tried importing the classes on the main timeline, and even including the directories of those classes on the classpaths list, but no dice

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:

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.

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?

I am working on a project in which I am suppose to maintain an array of movieclips, and I can also convert the movieclips into bitmap data. So I would like to know which one is the best to use either maintaining movieclip array or bitmap data array.

When you do, you'll see that the movieclip should obviously be at position (0, 0) on the stage. However it appears at (25, 5)! if I leave in the original "this.x = xx;", then it appears at (50, 5). If I also leave in "this.y=yy;" then it appears at (50, 10).

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{
//
}

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.

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 a library symbol, exported for Action-Script and to Frame1. Now in the document Class, i write
public class Test
{
public function Test():void
{
[Code]....
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???

When we want to know if a MovieClip animation has ended, we use to listen the enter frame event and check if current frame is the final one (where the movieclip frame has a stop).
But we've thought on a new idea: to extend MovieClip and override stop method. In the override we dispatch an event indicating the animation is ended. So, we hope the clip to find a stop in a frame, call the overriden method and execute both, the super.stop() and the event dispatch.

My code is simply looping through an xml file and creating 'pages' (which are later animated).
This has all worked fine but now I want to add a sprite over the entire contents of the page if the contents of the xml contain a URL.
At run-time I can see that the checks for the URL are being processed correctly and that the overlay is being generated, but I cannot "see" it on the page.
The following code is located in a for loop for every page in the xml file:
var page:Page = new Page(); //MovieClip in my library
// ... other stuff
var textMC:FadeText = new FadeText(xml); //load the text from the xml fragment for this page
[Code]....
I now believe it is something wrong with the XML. It is correctly parsed XML (otherwise FlashPlayer would throw exceptions in my face) and it appears that this code works on every page except the second. Further more, if the second page is set as visible (a flag in the XML determins if the page is created or not) then none of the other pages overlay works.

What is the difference between a movieclip and a sprite. Why some programmers using sprite instead of a movieclip? What is the advantage of using sprite? Can we use sprite in the stage? Will the sprite reduce the space occupation than a mc?

I want to send a string to a function and then, via the string reference a Sprite. Are theire any other ways to adress a sprite with a String value?I thought this[myString].alpha = 0.5; was gonna do the trick but i keep getting (1010: A term is undefined and has no properties.). I tried every possible solution it feels like. Delaring Strings locally and Global...but i can�t get it to work. And the String is well spelled btw![code]

It's never been an issue since I always anticipate it but just wondering...
if I put a MouseEvent listener on a movieclip/sprite...
Code:
whatever.addEventListener(MouseEvent.CLICK, clickAction, false, 0, true);
function clickAction(e:MouseEvent):void {
trace(e.target);
}
that traces a movieclip inside the intended target...
