ActionScript 3.0 :: Finding A Flash Library Object's Base Class At Runtime?
Feb 9, 2009
determine the base class of a Flash library object at runtime, using Actionscript? The toString method gives me the class of the object, but what I'd really like to determine is the superclass of the object. So, if I have an Actionscript class called "Fruit" and I created many different Fruit types in the Flash library ("Cherry", "Apple", etc.), is there a way in code I can determine that an "Apple" is a child of "Fruit"?

I'd like to set the base class of a library asset at runtime,rather than specifying it before. Is this possible? I'd like it to just extend movieClip, but at runtime change that to extend a custom class.

So I know you can assign a base class to a library definition within the Movieclips library information field but If I have 30 items in the library and I change the Base class this becomes a pain in the ass, can this be done programmatically when I instantiate the library definition?
var new_shiz:MyItem1 = new MyItem1(); // Needs to have a generic base class of MyItem

I have a symbol in the Library with a Base Class that extends the MovieClip Class and adds some additional functionality. I want to be able to export this from the Library by right clicking on the symbol and selecting Export SWF. I was hopping this would essentially give me the same results as if the symbol contents was on the main timeline and I had declared the Base Class as the Document Class. When I import this SWF using the Loader Class it seems to loose all of Base Class functionality and think of itself as a MovieClip.
Looking at the below sample code, the alpha property is correctly set but the param1 getter is unaccessible. What the hell is going on?

I have a main swf file, Main.swf, which has an associated .as file, mainClassCode.as[which actually does nothing, it is not being used]. Main.swf, loads an external swf,ContentHolder.swf, which has a base class contentHolderClass.as. Now all the stuff that happens within ContentHolder.swf, is within the contentHolderClass.as. There is nothing on the stage within ContentHolder.swf, and everything is being done by the base class. Now when I test the ContentHolder.swf on its own, everything runs fine. But the moment I load it through Main.swf, I get a million errors, stating that none of the movieclips in the ContentHolder.swf library are being recognized by contentHolderClass.as..Why could this be happening??? I have imported contentHolderClass within Main.swf [in frame 1], and I after I addChild(ContentHolder loaded swf)

i have a flash file with a number of movieclips in the library - various bubbles that can be popped at a clilck. The fla has a document class - BubbleGame.as, and the various bubble mcies in the library are all exported for action script, (using their own names, but) with a mutual Base Class - BubbleBase.as, in order that all the various bubble movie clips have the same behavior: load in a random position, play out their own timelines, be popped when clicked, and if not popped - reload in another position.
This is all working very well, however, I want the movie clips removed if they hit an object on the stage. The object has an instance name of sym_mc, and I have tried various bits of code to cause the bubble to be removed when it hits that object, but i either get errors or nada.
I tried doing the hitTestObject code in both the document class and the base class. It seems more appropriate to have it in the base class - BubbleBase.as (below), because that tells the bubbles what to do.

This question stems from this question that I asked yesterday.I've followed Theo's advice and created a .swc with all the common classes and added the .swc as an external library to my module .swf. This all seems to have worked smoothly--I don't get TypeErrors and my classes are all present in the catalog.xml of the .swc file when I unzip it--but now I've encountered a new problem: when I try to link a symbol in the module .fla's library to a base class from my .swc rsl, it says the base class definition can't be found in the classpath. The whole reason I want to use rsls is so I can do this,If I now include the project's source path or the .swc in the normal (not external) library path, will that cancel the sharing benefits of the rsl, or will the compiler still know not to compile the shared classes into the module .swf?

I have this Fla which contains a symbol that is linkaged to a certain class that is in my project. That class inherites a base class named CMovieClip which resides in one of the libraries that is in the class path (and inherites from MovieClip).Of some reason, every change that I do in the base class doesn't seem to influence the resulting linkaged class, much as if this library is cached somewhere that I can't feagure out.I tried to create the same conditions in a separate Fla but it does not repeat the issue.I tried to duplicate the symbol but the issue isn't solved that way.

I have two SWF files which I shall call container and slave. The slave file contains a movieclip that extends from a class I shall call base. base extends MovieClip and is compiled into an SWC. slave includes this SWC as a runtime library, while container includes it as merged (and does reference it so it should be compiled into the container SWF).
The container loads the slave like so:
bgURLRequest = new URLRequest(slaveUrl);
var context:LoaderContext = new LoaderContext(false, new ApplicationDomain( null ), SecurityDomain.currentDomain);
bgLoader.load(bgURLRequest, context);
When this loading happens, I get the error that class base was not found. I suspect this has something to do with the presence of the ApplicationDomain in there. I'm not sure what it does exactly, since I didn't write this loading code myself (but I do know that it's there for a reason so it can't be simply removed).

I have a main.swf which loads a module.swf and the module.swf loads some assets.The module.swf works standalone and also needs to work when loaded by main.swf.But unfortunately the module.swf can't find the assets when loaded by main.swf because the assets aren't located relative to the main.swf, but are located relative to the module.swf.As I can't touch the module.swf and I'm also unwilling to change the directory structure, I am looking for a solution close to the a "base" parameter which can be used when a swf is embedded into html

I have a flash file in folder "/" which loads another flash file in folder "/xyz/". The second flash file will load several resource files on its own. Now flash is looking for the resource files at the base folder "/" and instead of the other loaded flash's folder "/xyz/". The second loaded flash file is provided by a third party and can't be modified. Is there any way to dynamically change the base folder of the "application" at run-time? I've heard about the html swf tag "BASE" so I've tried loading the second flash file with a ".....?BASE=/xyz/" but it doesn't work.

I have a program where I have multiple classes derived from a base class. I want to take all instances of the different subclasses and put them into an array. Is there a way I can search for anything derived from the base class?For example, right now a get the number of children, then see what they are, so:
for (var i = 0; i < this.getNumChildren(); i++)

So Is there any fast library(s) for finding human eyes and mouth in Flash in such case? (pure Actionscript or HaxeJavaC++C port in SWC form.. What do I know Is - some libs are described in this presentation [URL]..

I'm having a little trouble setting up a new project (an e-Learning) that I think will benefit a lot from RSL.My case is something like this[code]...
The Main will be the first movie to be instantiated, then, all that is necessary from here will be download.Every lesson will be put in a fla/swf apart from the "Architecture" (that is the Main, Scenes, Navigation and a whole bundle of classes called Engine) and will be added at runtime inside the Scenes.
The Engine is responsible for handling repetitive and necessary tasks, events, common methods, communication with server, among other things.The Navigation is responsible for handling user input, as the navigation (next/prev lesson and such), and then passes it to the Engine, that will manipulate the Scenes (and it's children).
Well, I have some restrictions too:Every swf file that will be handed to our client need to have less than 80kb, which means I'm tied.I can't compile the whole thing as a package ready to delivery.As size counts, I need means to alleviate the load as much as possible.So, I searched a lot these days and found out RSL.I've created some tests to know better how to use this and, of course, got into a trap.
I haven't been able to set up my Flash correct, haven't any success with the "Library Path" (under AS3 configuration), haven't been able to compile classes inside the SWC...
Another thing is that I won't make the lessons, only the Architecture.Those lessons will be created by people that may not have any knowledge in AS3 (OOP or program logic) at all.And I'm not inclined to delivery the whole engine (source code) to anyone from outside that may mess with it, making the whole app (apps, in fact, we'll produce hundreds of e-learnings).

I have this base class
package sevengames.miranda.front.res {
import flash.display.MovieClip;
import flash.text.TextField;
[Code].....
I then, in the Flash document, create a movie clip which has this class set as the "Base class" in the properties. However, if I then do this.updateText(); in the movie clip's frame script, it complains
TypeError: Error #1006: updateText is not a function.
at miranda_fla::MenuButton_3/frame1()
Why doesn't it work? I know the class is read and compiled, because I had an error there which was reported.

I have a problem and I'm not really sure where to start. What I have is an animation of a character in the library. The Character is made up of a few movieclips for the body that move about and one for the face that holds a stock photo.I have a camera section that grabs an image of the users face and now what I need to do is swap the stock face photo for the one taken in the last scene.

Kindly note I am not asking what SWCs are used for, I know about that. I want to know, the use of RSLs in flash. Say i have some useful classes which i currently am using by specifying the particular folder as an "Additional source folder". So, can i make use of RSL here. If not, when and why i need to use RSLs ( I use SWCs without any problem, but i wanna know how to make use of RSL, without making SWCs, ie just by bunch of actionscript classes )

For some reason Adobe doesn't allow us to change the size of the handle in the default slider component. This handle is small and hard to click on quickly. If you try to increase the size of it graphically it just gets resized back down to 13x13 pixels. I've looked into the Slider.as code found in:
Program Files(x86)/Adobe/Adobe Flash CS4/Common/Configuration/Component Source/ActionScript3.0/User Interface/fl/controls/Slider.as
And found that on line 803 there is the code thumb.setSize(13,13). I tried changing that to 60,60 but it doesn't change the size of the handle. I don't know much about classes and I didn't think you had to compile these. I thought that in Flash when you clicked on the Components button that it loaded these classes in at that point but I must be wrong.
ActionScript Code:
override protected function configUI():void {
super.configUI();
thumb = new BaseButton();
thumb.setSize(60, 60);

I am using Flash CS5 (assets) and FlashDevelop (code) for my project. We have about 20 fla/swf's that contain textfields. All of our textfields use the same Font, and the font is specific to our company so won't be installed on anyones computers, hence it needs to be embedded.
My ultimate goal is to have one single font embedded that all of the textfields use, for 2 main reasons:
Whenever we add more characters to the font (other languages), we only need to add them once and not 20 times The file size doesn't blow out dramatically
I'm having great difficulty in trying to achieve this. It seems that everything I try, characters are missing (only characters entered in the text property of the textfields in each fla seem to be embedded).
The latest solution I am trying is using Runtime Shared Libraries, as this seems like it should work. I have an fla called FNFont.fla. It contains just one object in the library, the embedded font. The font is exported to AS3, exported in frame 1 and exported for runtime sharing. The URL is FNFont.swf (all swf's are in the same folder).
In all the other fla's, I create the font object in font embedding. I tick Import for Runtime Sharing and give it the same class name as the one in FNFont.fla. The URL is FNFont.swf. The fla(s) contain many textfields using this font. The textfields have instances of themselves as children of other movieclips.
When I run the program and attempt to load a movieclip that contains an instance of one of these textfields, I get the error:
[Fault] exception, information=ReferenceError: Error #1065: Variable FontName is not defined.
FontName is the class name of the Font object in FNFont.fla and all other fla's. It is not the instance name of the textfield (nor the class name), so I don't understand how it thinks its a variable.

I have a Main class that I call from the .fla file. Everything work fine until I set a object in the Library "export for actionscript"... after that the stage didn't work anymore, the stage now return "null", just because I checked an object to "export for actionscript". I'm using flash cs5 and it never happen to me with the early version of flash.
