ActionScript 3.0 :: Use Library Movieclips With Classes?
Jan 15, 2010
I've created a carousel class which takes one parameter, an array of menu item names, these will then be displayed on the carousel. I've then created two movieclips for the left and right controls, added them to the library and given them classes of their own.Within the carousel class I instantiate instances of the two control classes which then enables me to add event listeners for rollover and rollout.
What I'd like to know is, is this the best way to do this short of creating the controls using pure actionscript?I'd like to not have to add the class properties for the left and right controls and have a situation where I could just give them the right name and they would work or maybe pass them in as parameters and use them that way.

I have an array of ingredients for soup as strings. These ingredients are also movieclips in my library, all linked with an identifier. I want to add the movieclips to the stage dynamically.
I tried getDefinitionByName but I keep getting an error that the variable "appel" (veg[0] in this case) is undefined. And basically, I only have a general idea what I'm doing here, so I would be grateful if someone could explain it to me or link me to a helpful tutorial.

I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?

I'm having some doubts about how to access some features of embedded files and loaded.
For example, I created a .fla and added a symbol to your library - a MovieClip with name and class circle. Then convert the .fla to .swf, thus becoming test.swf.[code]...

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.

The one thing that was never covered (that I read) was how to set up your library. As a result, I have been guilty of starting a project folder and copy/pasting all of the classes I need into each project folder. (As a result I have like 30 copies of TweenLite on my PC). I have done some searching, but the topic seems elusive... I have also read where most people use a reverse web address format (e.g., "com.site.page"). So my questions: Is there a standard way of setting up a library for your classes?WHERE does the "com" folder live on the directory (ex: c:com, or c:Adobecom, etc).How do YOU have your library set up?

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.

How do you access Library items from classes other than the document class?For example, if I create a movie clip in Flash and Export it for Actionscript with the name Foo, I can do this in the document class:
Code: Select allvar f = new Foo();
this.addChild(f);
And it appears on the stage, as it should. But I need to be able to create other instances of this object from other classes. If I use the same code above in SomeOtherClass.as, I get nothing on the stage, obviously because this class doesn't know about the Foo object in the library.

I've been heavily mired in 3D recently, and decided to pay a visit back to good ole Flash.
My problem is this. I'm extending the MovieClipLoader class to create a Preloader Class (yes I'm sure it's been done fifty billion times but). I'm trying to refer to a symbol in a common library, the preloader symbol itself.
Inside my class I have this
Code:
function onLoadStart(target){
baseClip.attachMovie("preloaderTemplate_mc", "preloader_mc", 500, {_x:0, _y:20, _xscale:75, _yscale:75});
baseClip.preloader_mc.gotoAndPlay(1);
}
baseClip is a MovieClip object which takes a MovieClip passed to the constructor of the class in the FLA. (say a container movieclip which has a target clip preloaded into it) The class does load the target clip into the baseClip, but doesn't show the preloader, which makes me think I'm not referring to it properly.

1. I've got a Main Document class, that loads external swf each with its own document class (they are pages and pieces of the site).
2. The Main class makes use of some movieclip simply instantiated from the GUI library. It all goes fine.
3. The external swf have references to the Main class, and here start problems: when I compile them, I get an error for every library mclip used by Main. See the attachment. A simple trace(Main) is enough to start getting all that errors.
A partial solution is to uncheck Strict Mode in publish settings

What I want to do is compile an .fla with nothing on the stage but several of the movieclips are set to export on first frame in the properties linkage manager. When the .swf runs, I want to loop through and get the names of all the exported assets so I can place them in an array and manipulate them later.
I want to turn the code over to the art team where all they have to do is attach my .as file for the document class. I will not know what they name their movieclips, yet they are instructed to name them alphabetically according to what order they should appear. (My code is a sort of self contained slide show).

I have a series of large fla files that were being published into swc's and then used directly in an flash project. Probably a total of 1000+ objects. As the number grows the final compiled swf is getting quite large so I want to download individual swf's of each object only as needed. I then need to be able to access and clone the object via classname from the final AS project.
The issue is the only way I have found to export each one is to 1) copy and paste it into a new fla file 2) double click to 'edit' it to force it included, 3) reset the linkage (class) name since it was wiped, 4) publish (i.e. file->publish) and name this swf. This will take quite a while for 1000+ of these.
While you can right-click on each item in the library to save it as a swf, it appears NOT to include the classname etc, just the item. Once I download this, I cannot clone to use it more then once without downloading it again which is unacceptable.
Is there a faster/better way to generate these swf's?
(I did look into xfl briefly but it looks like writing a script to do this given some of the unknowns there will take longer then just doing it by hand.)

let's say I have a function in a package like this:
ActionScript Code:
package{
function traceObject(target:Object){
trace(target);
}
}
Now, I want to use this function in every flash application just like I do with
ActionScript Code:
import flash.display.*
1) How can I do that?
2) Can I have classes and constants in the same package too?

Im working on a App that is using a external swf as a container for some graphical assets. An asset is a movieClip symbol with a class name attached to it. for example ASSET_1. I load the swf with the Loader class into the app. Its working fine I can also access ASSET_1 with this technic:
//--- inside onLoaded
var ASSET_1:Class = event.target.applicationDomain.getDefinition("ASSE T_1") as Class;
var asset:MovieClip = new ASSET_1() as MovieClip;
addChild(asset);
my problem start when im loading a second swf and than i try to access "ASSET_1" again, and the class doesn't update itself, the content is the same as in the firs one.

I have several library classes that I am loading from swfs external to my main swf. These swfs all use the native tween class (import not extend). This means that I have the tween class creating bulk several times over (as well as the extra bulk for having to load a swf rather than having the class internal).Is there a way that I could make the tween class accessible at runtime to the loaded swfs without having it create the same extra bulk in all of the loaded swfs?the only solution that I can think of is to create yet another swf with the tween class as a library object, that would be loaded at run time by all the other loaded swfs.

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 fljŨt provided, i wrote my own command to accomplish this task.[URL]..

can you declare multiple classes and then register each movieclip from the library to a different class? It isnt working for me.I created two different classes and created two entire different movieClips and registered each movie clips to a different class.However, I can only use on movieClip at a time, when I use the duplicateMovieClip... command to create copies of the movieclip, i find that only those movieclips, whose class i declared first, appear on stage.

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 am having some trouble with Classes with respect to a movieclips 'As 2.0 class' in the linkage settings.After an attachMovie i am expecting my Class members to exist but they are not
OK, This is what i was doing...I create a MovieClip called Class1_mc and another called Class2_mc, original eh.i then stick an instance of class2_mc INSIDE of Class1_mc, call it clipinner
ok so i assign Class1 to Class1_mc and Class2 to Class2_mc via the linkage settings.

I'm surprised that a XML loader works only if it is embed in a MovieClip class and not any external class.
I have my XMLLoader class and the loader didn't work.
I've added "extends MovieClip" and it worked.

After switching to AS3, I've been having a hell of a time figuring out the best way to manage MovieClips that have UI elements spread across multiple frames with a single class. An example that I am working on now is a simple email form. I have a MovieClip with two frames:
the 1st frame has the form elements (text inputs, submit button) the 2nd frame has a "you" message and a button to go back to the first frame (to send another email) In the library I have linked the MovieClip to a custom class (Emailer). My immediate problem is how do I assign a MouseEvent.CLICK event to the button on the 2nd frame? I should note at this point that I am trying to avoid putting code on the timeline (except for stop() calls). This is how I am 'solving' the problem now:
Emailer registers an event listener for a frame change ( addEventListener("frame 2", onFrameChange) )On the 2nd frame of the MovieClip I am calling dispatchEvent(new Event("frame 2")); (I would prefer to not have this code on the frame, but I don't know what else to do)
My two complaints with this method are that, first I have calls to addEventListener spread out across different class methods (I would rather have all UI event listeners registered in one method), and second that I have to dispatch those custom "onFrameChange" events. The second complaint grows exponentially for MovieClips that have more than just 2 frames.
My so called solution feels makes me feel dirty and makes my brain hurt. I am looking for any advice on what to do differently. Perhaps there's a design pattern I should be looking at? Should I swallow my pride and write timeline code even though the rest of my application is written in class files (and I abhor the Flash IDE code editor)?
I absolutely LOVE the event system, and have no problem coding applications with it, but I feel like I'm stuck thinking in terms of AS2 when working with mutl-frame movieclips and code.

I have a designer who has created a set of movie clips that I want to create instances of using ActionScript, but all I have is the name of the MovieClip as it's stated in the library (not the instance name).
Is there any way to create instances of the MovieClips using just their name? Or do I have to create separate classes for each?
