ActionScript 2.0 :: Nested MovieClip - Classes And Linkage
Dec 7, 2007
In my project I have to classes that inherit the MovieClip class. Then I create a movie clip and in the library I click on linkage and I set on AS2 class field the name of the first class. Inside this movie a create another movie clip and I set his AS2 class to the second class. The problem is, when I run the file the properties of the nested movie clip are not available for the parent. What a mean is that in the constructor of the first class I cannot acces the methods of the nested movie clip. Somehow I need the nested movie clip to be initialized first and then the parent.

I have just started my first project using AS3.0 and Flash 9 this week.I feel like I know AS3.0 from my flex experience very well, but it is downscaled for Flash 9. Anyway I have looked for this issue in the forums and maybe I am just missing something.I have a class we'll call MyClass which extends Sprite. I have several methods in there that update things like rotation and position based on events it is listening for via the model. I even have a trace statement in the constructor for testing.
Now maybe this is just stupidly obvious but when ever I set a library element to link with the class (i.e. linkage = MyClass), all my script fails to work. If I remove that linkage and work from a purely data perspective it works as expected.I have the project settings to Flash 9 and AS3.0 so that shouldn't be an issue.

I'm kind of messy and I ussually change the class linkage name a lot .
What happens with unused anymore linkage classes ? Are they automatically deleted by flash CS3 IDE ?
Edit:Long time no answer What I mean is not if they are still available (haven't tested but probably aren't) , what I mean is will those linkage classes be compiled into swf increasing the size or not ?

I am starting to create classes instead of using the timeline and I am learning a lot more even if mistakes happen more often. However I have a question about linkage & library. For example let say that I have a ball pic called Ball1.mpg. I copy and past that Ball1.mpg in my folder where the Fla file is as well as the as file. If I want to utilize this Ball1.mpg in my code using Flash do I absolutely need to import into my library and link it and export using linkage? Or can I use the object Ball.1mpg just using actionscript. Of course that implies that I would use an actionscript class not the timeline.

I'm an intermediate AS2 coder starting to use better OOP practices. I have searched for the answer to this but have not found anything, perhaps because everyone else learned it a long time ago.It appears that classes which extend an MC which is contained inside a different MC do not run their constructor immediately after the containing MC is instantiated. Also this MC's methods are not immediately available. As a result I need to wait a bit, by using onLoad or another frame.Here is an illustration which I have made as slim as possible:
LIBRARY:
--Symbol with ID "ball", linked to AS2 class "Ball".
--Symbol with ID "box", linked to AS2 class "Box". This symbol contains an instance of "ball" which I dragged in there and gave an instance name "ball_0".
--Symbol with ID "launcher", linked to AS2 class "Launcher".[code].....
QUESTIONS: How can I fix this so that setB would work in the above example? I have found two workarounds but I wonder if there is another which feels less kludgy.
Solution A): As seen in the example, put into Ball an onLoad function (or maybe just its constructor) which then runs any initialization functions. As a result I need to store in the object some properties which the object can find in itself and use for initialization.
Solution B): Put the method call on a timeline frame after the frame in which the attachMovie is done.
At the heart of this question is, why can I set the ball's properties (as seen with setA) but not be able to call its methods successfully? On one hand, I can see that the thread is busy with the box's initialization and can't be expected to run ball's constructor right away, even though ball has been instanced. But on the other hand, I am actually calling a method of an instance which is obviously there, so shouldn't it have the common decency to do as I ask?
Bonus question is, is the fact that this does not work a bug in Flash AS2 or is it perfectly to be expected due to some CS common sense which I lack?Another bonus question is, is this a harebrained way to use Flash AS2 classes—linking symbols to AS2 classes which extend MovieClip (or which are subclasses of classes which themselves extend MovieClip), and using attachMovie to instance all of these MCs except the one "Launcher" which is the only thing on the .fla's stage? It's a cornerstone of my architecture so I'd like to know if this is utterly daft.

Flex complains if I want to create an object from a library symbol with linkage: 1180: Call to a possibly undefined method [linkage name]. So to avoid this, I create a class for that symbol, in this case extending BitmapData using Flex's new ActionScript Class feature. Flex create that class for me and the constructor looks like this: public function CustomBitmapData(width:int, height:int, transparent:Boolean=true, fillColor:uint=null)

For some reason I can't get this nested set of functions to work, it executes the first tween and the tween invoked after motion of the first is finished but it doesn't ever get to the third!
ActionScript Code:
var t1:Tween=new Tween(p1,"rotationY",Strong.easeOut,90,0,50,false);
var t1x:Tween=new Tween(p1,"x",Strong.easeOut,-900,0,50,false);
t1.addEventListener(TweenEvent.MOTION_FINISH,onMotionFinished);

I am trying to create a gallery. I am having a problem coding the document class for a menu window ("galleryPane"), which is to be called into the Main class at runtime. In particular, I am encountering problems dynamically creating the thumbs container. I want the thumbs container to be accessible from both the galleryPane class and the Main gallery class [the galleryPane class will need to control thumbsContainer scrolling properties, and the Main class will load content into it].
I have an empty movieclip in the .fla library (with a class name of "All_thumbs" for exporting purposes). In my galleryPane class, I have created a new public instance of this (called "thumbsContainer") and have added that within the nested structure in the menu. However, when I call it in a later function to manipulate its movement, the undefined term error is thrown and I cannot understand why. Here is what I have in the galleryPane document class.
ActionScript Code:
package {
import flash.display.MovieClip;
import flash.display.SimpleButton;
import flash.events.MouseEvent;
import flash.events.Event;

I'm trying to create a linkage to swap movie clip dynamically. I already create a linkage and after my movie clip symbol actuall say Export: contact_idea. But when I try to attachMovie("contact_idea"). It does nothing. Is there anyway that I can test that the linkage is actuall linked?

I have a large flash app (> 100k) w/ its own looping preloader animation in the first frame. This preloader should happily spin while the app loads. (For various important reasons, I can't use a separate SWF to load the app.)Bug:When I export the classes in a later frame, all of the preloader animation's simple timeline commands (stop, gotoAndPlay) stop working.Test:I can reproduce this in a very simple test:The red ball should stop (as seen in example 1) and doesn't (example 2).Question:Do any of you know how to get around this? I've been trying everything I can think of and haven't found a solution. If this is unbeatable, it seems the only real timeline preloader you can do is a code-drawn progress bar

I have a Hero class that extends a Unit class that extends a SelectableObject class.[code]I have a movieclip in the library that links to the Hero. Inside the movieclip is another movieclip with the instance name "selector".In the Hero I can use selector.gotoAndStop (n) because the movieclip is linked to that class, but I can't do that for the SelectableObject because it's not linked to that.Is there a way to make selector.gotoAndStop (n) work for the SelectableObject? I can't even do var something:* = this.selector because the movieclip isn't linked to it.Or should I just remove the instance name for the selector in the movieclip so I can declare var selector:* = this.getChildAt (1) in the SelectableObject (the selector being the second child)?

I have been looking around the web and in books for the last few hours and I can't seem to get an answer that is clear, at least not clear to me Question1 If an external class such as a document class is used, you cannot simply access a nested movie clip that has been dropped on the stage from the library using dot syntax, is this correct?

In Flash CS3 I was able to duplicate any MovieClip from an external SWF by loading the SWF, and then executing the following code:
var targetClass:Class = MovieClipToDuplicate.constructor;
var duplicate:MovieClip = new targetClass();
Note that the MovieClips I was duplicating did NOT have any linkage explicitly defined. Flash would automatically assign a unique class to each MovieClip. Now, in Flash CS4, when I try to do the same thing the .constructor property returns only the "MovieClip" class, such that the "duplicate" variable above is but a blank MovieClip. If I compile the external SWF using CS3, my old code still works. But I want to do it in CS4.

I have a class that has a constructor which accepts some parameters.
Code:
class MyClass {
var myNumber:Number;
function MyClass(number) {
myNumber = number;
}}
Is there a way I can link this to a movieclip and pass the parameter? From what I've found there are two ways to link the class to a movieclip, one using the registerClass and another typing the name intro the Linkage Box in the Library. But in both cases there are no parameters being setup.
