Actionscript 3 :: Accessing External Library Symbols Dynamically?
Aug 14, 2010
I am loading an external SWF containing uninstantiated MovieClip Symbols. I can get the SWF loaded, no problem. If I call:loader.contentLoaderInfo.applicationDomain.getDefinition( "TestClip" ) as ClassI get the class of a Library symbol called "TestClip", which I can then instantiate. Jawesome.The issue I'm having is that basically I want to have access to all of the Library symbols without needing to explicitly know their names. I was hoping to use:
describeType( loader.contentLoaderInfo.applicationDomain );
...to get reflective access to the Library symbols, but the XML returned doesn't seem to include any references to them. Perhaps I'm calling it on the wrong object? I also don't want to have to explicitly create coded instances to gain access. This is for a tool for Flash artists, and it's important to avoid code, even simple code.

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'm currently working on a game. I'm breaking down each piece of the game into individual classes and movieclips. The intro begins by going to the main menu which is a MC in my fla library. This is called through the document class. then all actions the main menu MC performs are commanded through the MainMenu class. When starting the actual game, MainMenu calls a function from the document class, after it is removed from the stage, that puts an empty movieclip called Level on the stage.

I've been working with/around and dodging a situation where I'm trying to access FLA library movieclip assets, but NOT from the document class. I capitalize this because this is my 4th forum posting. I know the answer to that one:
instanceName:ClassName = new ClassName();
The easiest solution for accessing library items from a SubClass looks to be this:
// at topimport TestLocalMC;// in constructorvar box:TestLocalMC = new TestLocalMC();addChild(box);
However, it doesn't show up. I tried a fake non-existent class. It gave me an error so I know it's referencing a Class in the library that I supplied. If I trace the object, it shows up. If I trace the X value, it says 0. So logically, it should be right in front of me..but it's not there! .Am I on the right track? Is this familiar at all to anybody? Is there something I'm missing?
if I could reference FLA library items with a bit of freedom from the document class. Having to go up the hierarchical class tree everytime to retrieve a movieclip is getting rather painful.

I can reference the main library Class, but the clips nested within are coming up undefined and the usual parent.child.child method of accessing clips using getDefinition isn't working.
Here's my coding:
Code: Select allpackage {
import flash.display.*;
public class Menu extends MovieClip{
[Code]....
I tried both instances naming and Class naming in the library. It loads the clips within the menuClip. I can see them, but I don't have access for some reason.

I need help with oulining dynamic text. Is there any plugin or external library to do it dynamically?I made imitation of outline text by copying written text, and placing it under the original. Then increase it's width and height, change it's color. But it is not looking so good as i thought it would look..

I am making a Thumbnail class which is part of my Photo Gallery Package that I am building with the intent of automatically generating my thumbnails. I do not want to limit myself to just AS3 animations, I would also like the ability to use timeline animations. I have a system using "in" and "out" for frame labels which I find very efficient and I get stuff done quickly. So I created the thumbnails holder MovieClip with the animations and have it linked in my Library, however, when I try to pass it to my Thumbnail Class, I only get one instance and I need to create several instances.
Document Class
ActionScript Code:
var thumbCont:mcThumb = new mcThumb();
thumbNails = new Thumbnails(thumbCont);
Thumbnails Class
ActionScript Code:
var thumbContainer:MovieClip;
public function Thumbnails(thumbCont:MovieClip,) {
thumbContainer = thumbCont;
}private function createThumbs():void {
for (var i:int = 0; i < aThumbs.length; i++) {
[Code] .....
I eliminated most of the additional stuff. What this does is that it doesn't create several thumbContainers, rather it just uses the one. So how would I be able to generate several of them? I can obviously create an Array with them and create them in my document class, but if I can avoid that and have my thumbnail class do it by itself, that would be perfect.

I am using CS3 / AS2 and was wondering if it was possible to load a movie into a symbol, not just an instance of that symbol, from the main timeline. I tried exporting the symbol for actionscript then using loadMovie but I suspect that is not the correct way to go about this.
PHP Code:
symbol.loadMovie("urlToMovie");
Is it even possible to do this or do I have to change every instance of the symbol individually?

Let's say I have Class Holder linked to a MovieClip holder_mc. holder_mc has a child held_mc that has a Graphic Symbol pic_gr. pic_gr has multiple frames.
From the Class file of Holder, how would I change the frame of pic_gr? I also didn't see a way to name the instance of pic_gr, is that right?

I have an .fla I created a while ago. In it is a movie clip in my library which I now want to use in a new .fla. This movie clip is reliant however on an image which is also in the library. I have tried selected both the image and movie clip, copy them, and paste them into my new library, but this doesnt work. I have tried cutting... I have tried duplicating and copying the duplicate. Nothing seems to work. Is there anyway of getting a symbol from one library into another?

I've got a question which is primarily an OOP question, but it is specific to AS3 in it's implementation.
I writing an interface which consists of displaying a (circuit) card rack which holds twenty cards of various types. Some of the properties of the cards are common to all cards such as slot number, card type, id, etc. They also behave similar when clicked on, taking you to another view.
It seems to make sense to create an abstract class (Card) that has all the common properties and behavior of all the cards, and then extend that class to create the specific card types, but the problem is that the display objects representing the cards are movie clip symbols in the library.
It boils down to this question: How do I extend a class that is already extending the movie clip class (a symbol in the library)? I know that AS3 doesn't allow it, but I figured someone has probably run in to something like this before.

Does anyone know if it's possible to have Graphic-type symbols in a shared library as it won't let you add an identifier to them? It's ok to use Move Clips but they increase the file size.

I'm using Flash CS4 with Win7 and if I create a movieclip symbol in an FLA file such class name such as GreenBox. When I put the following line into my actionscipt 3.0 code, I get the error: "You cannot debug this swf because it does not contain actionscript.The line of code is:vargreenBox:Green Box = new GreenBox();Any ideas what's going on. Never had these problems with CS3 and Win XP.I did double check to see if I had the debugger version on Flash Player.

I've started a new cs3 flash file. I've created a few symbols, scattered them about the stage, then gone to start writing my class file. I've created the class fine and i have created an external .as with the same name as the fla file (miniGolf.fla and miniGolf.as). The problem is that i can't link the fla to the .as. Every time I click the little pencil icon I get an error saying:
"You must specify a unique class name that is not associated with any library symbols"

how Flash handles garbage collection of the library symbols? E.g. If I attach a Bitmap symbol to a MovieClip symbol(drag to the first frame, MovieClip linked to a MovieClipClass) Is the following enough to make the movieclip eligitable for garbage collection?e.g.
ActionScript Code:
var mc:MovieClipClass = new MovieClipClass();
addChild(mc);
//some time later
removeChild(mc);
mc = null;
I wonder if it will remove the bitmap loaded as well, or at least make it eligitable. I'm loading massive bitmaps, when I create other new MovieClipClass I notice the image loads instantly as oppose to that bit of lag.Or is there a different way to manage the bitmaps for the bitmap symbols?

I've created a few symbols (movie clips) in my library. They are basically "panels" for user input etc. I've sized them carefully and do my best to have them stay within a 320x240 size. But when I load them they come in with larger width and height dimensions...as if there are some objects/symbols/graphics that are invisible or something.
This happens with EVERY library movieclip i've created.

So I added a bitmap to my library in flash CS5, and in its symbol properties I checked "Export for AS" and "Export in Frame 2" (I set Export Classes in Frame: 2 in AS settings.) On the first frame of my main timeline, I have
Code:
trace("loaderInfo.bytesTotal: " + loaderInfo.bytesTotal);
trace("loaderInfo.bytesLoaded: " + loaderInfo.bytesLoaded);

I have just started using Flash CS5 recently and have a question about the classic tween. I have noticed that when I make a classic tween Flash automatically makes symbols out of my grouped objects. I have worked with previous versions and it was sufficient to just group my objects on the stage to make a tween. Is there a way to turn this feature off? I'm an animator and it's very annoying and messy to make a symbol out of all the objects I want to animate.

I have a package that extends my sound class that I want to also control the alpha of an existing symbol on my stage. I have read that this would be ideally done through some sort of event listener but I can't find a way to do it. Basically, my package generates a wavelength that I want to control the alpha of an existing library symbol. I have gotten examples to work the way I wish but can't seem to get my package to access the main .swf's library.
Here's the code:
package {import flash.events.SampleDataEvent;
import flash.media.Sound;
/**
* A dynamically generated binaural beat carrier wave Sound with frequency easing.

I have asked this question in another forum but haven't got an answer yet. I have just started using Flash CS5 recently and have a question about the classic tween. I have noticed that when I make a classic tween Flash automatically makes symbols out of my grouped objects. I have worked with previous versions and it was sufficient to just group my objects on the stage to make a tween. Is there a way to turn this feature off? I'm an animator and it's very annoying and messy to make a symbol out of all the objects I want to animate.
When I add a tween (CS3) I always used the Properties panel and choose "motion" from the tween settings. This way there's no symbols added in the library. Just noticed that there are also tween symbols added if I add a tween using right Mouse click or via the menu Insert>Timeline>CreateMotionTween. Never used this before. But I can't seem to see any tween settings on the properties tab anymore in CS5.

I would like to keep my project library tidy, which means deleting symbols I end up not using. However, I want to be able to find these symbols later in case I do end up wanting to use them for a related project. Can I create a library outside of a project, so I can drop these items into it for later use?

I have Main.fla and SkinA.fla. Both have MovieClip library item: MC_BrandLogo.I'm loading the SkinA.swf into Main.swf in the current application domain trying to replace the class inside Main.swf. If there is no library item in the Main.fla, I can instantiate MC_BrandLogo with the correct graphic. If the MC_BrandLogo already exist in the Main.fla then that graphic is used even though I loaded new one in the current application domain.Is there a way to replace existing linked movie clips with loaded dynamically?
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onSkinLoaded);
var context:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain);

I created an AS3 preloader, and placed the code for that on frame one. I then made a symbol, and placed it in the library. It was set to NOT export on frame 1, and the fla's settings had all classes exported on frame two. There were no references to the object until frame two. Then, flash crashed whenever I compiled without the "Export in frame one" box checked. To fix this, a friend suggested I start my game logic on frame 3, so it will have properly loaded frame 2. That seemed to work fine, the class was instantiating properly. Then, it turned out that it was not loading the movieclip, only instantiating the class. Again, this could be fixed by exporting in frame 1, but I really cannot afford to do that.
The same friend suggested I place an instance of the symbol on the stage on frame 3, and perform game logic on frame 4. They said this would initialize the movieclip properly. However, this was not the case. How can I load the entire symbol, graphics and all, without exporting to frame 1? This single symbol will contain probably 10-20 MB of graphics, so it needs to be preloaded. EDIT: To make a long story short, all I need is some way to load a movieclip so it can be used and visible and everything. EDIT: Is there any way to force-load a movieclip via AS3?

My workflow usually goes like this: i create a symbol in Flash IDE with textfields, containers, etc. Then I select "export for actionscript" and type in the classname (automatic declaration of stage instances, of course, is off). Then i create a corresponding classfile in FDT and declare all this textfields and other objects that are in my symbol. This is pretty routine and boring process that takes a lot of time.
Is there a way to automate it? Maybe some plugin for flash IDE that will automatically create a class file based on symbol exported for AS?
Update: So, following the answer Pavel fljÅt provided, i wrote my own command to accomplish this task.[URL]..

I need to change text in all textfields in my .fla file (Flash CS3).Looks like i should call JSFL function "fl.findObjectInDocByType("text", fl.getDocumentDOM())" and it would return all elements, but it returns zero length array. I there any another way to iterate threw all library items, and change values of TextField's in MovieClips ?

I'm building a video player using Flash CS4 (hereby referred to as "Flash") to create the graphic symbols and compiling and debugging with Flash Builder 4 ("FB4"). Here are the steps I take in my current workflow: --Create the graphic symbols in Flash. I've created a few different symbols for the player, but I'll focus on just the play/pause button ("ppbutton") here. --In the Library panel, I go to the ppbutton symbol's Linkage properties and link to a class named assets.PlayPauseButtonAsset that extends MovieClip. I do not actually have an assets package nor do I have a class file for PlayPauseButtonAsset as Flash will create them for me when I publish.
--In Flash's Publish settings, I set the project to export a SWC that will be used in FB4, called VideoPlayerAssets.swc. --After the SWC is created, I create my FB4 project called "VideoPlayer" and add the SWC to my path. FB4 creates the class VideoPlayer in the default package automatically. --In VideoPlayer.as, I import assets.*, which imports all of the symbol classes I created in Flash and are available via VideoPlayerAssets.swc. I can now instantiate the ppbutton and add to the stage, like this:
