ActionScript 3.0 :: Why Flash Creates Extra Instaces Of Class
Oct 7, 2009
I have linked a MovieClip to a class. After that I have places some movie clips of them on the stage. And now I like to do something with them, but I couldn't because some extra instances are created (I wonder how???) and they make me problems.The names of instances of the class I placed on the Stage are legs1 legs2 legs3,and the extra instances are: instance21, instance25,...(and they are not visible on the Scene)

I have two classes. One creates a class and the second one plays audio related to the class. When the user clicks the right answer the quiz gets removed from the stage, but my audio keeps playing. I am wondering how I remove/kill the audio class/object at that point.
My class gets created like this:
private var quizAudio:CaseStudyQuizAudio;
and further down:
quizAudio = new CaseStudyQuizAudio(theAudio);
When I tried to kill it, I was think this would do, but to no luck so far:
quizAudio = null;
delete quizAudio;
How is this done?

If an object, or say... a document class, creates an instance of a class (and stores it as a variable), and it doesn't pass any arguments to the constructor of the class, can that class object, by simply having a function of it called by the parent, tell who sent it that command/request?
In other words, can a class object know who called it (such as it's parent) via a (seemingly) anonymous call?

I'm building a small website. It's external class based and the ideia is to load the menus and content externally, by XML.
I'm using as base code an example from "Learning Actionscript 3.0 Book", from Rich Shupe and Zevan Rosser.
My class structure, I believe, is working well, but somehow one of the classes is not working properly.
The problem happens in line 21 and line 27. The error is the following[code]...

I'm still learning how to compile with the Flex SDK. And I'm learning how to use SWC files and [EMBED] statements to pull my assets into my application.With the Flash IDE, I can link a library asset to a class and it's automatically embedded into my custom class. So that's 1 asset in 1 class. With the Flex SDK and SWC files, it seems I can only* pull in assets at the variable level, so I end up with my custom classes containing yet another class -- this means I have an extra wrapper/decorator (whatever you want to call it) class that I didn't have when using the Flash IDE.Is this what people typically do? Doesn't that seem superfluous?I've read Colin Moock's 'Essential Actionscript 3.0', where he mentions something about embedding a SWF at class-level as binary data.

I have a question regarding createEmptyMovieClip in AS2. I have a flash file separated out into sections with labels and menu buttons which allow you to move you to the relevant frame/section (which contains the information/contents relevant to that section). This works fine. What I can't work out is that if I manually put a movieclip on the stage in my 'about section' and then add contents to it via AS2 then it only exists within the about us section. If I do it using createEmptyMovieClip within the actions for the about frame this works fine but it then always exists on every other frame of the project. I assume this is because it isn't actually creating it within this frame but I can't work out how to make it do this, even when i use this.createEmptyMovieClip it has exactly the same effect. I can obviously remove the movieclip completely each time a user moves to another frame that doesn't contain it but I don't want to do this as it contains a youtube video and leaving it means it doesn't have to be reloaded each time they come back.
I would be massively grateful if anyone could shed any light on this for me as I know i'm not getting how to place it correctly but i'm not sure how I should be doing it?

I load images into my .xfl project and use them amond movie clips - everything is ok at beginning. But after a some moment (which is absolutely undefined) Flash Professional CS5 starts duplicating all of them at saving and new copies names with "Copy 1", "Copy 2" and so one, or just with blank string. Because Flash duplicates them EACH saving, so after a several savings Flash refuse to save at all (shows "Too big project ..." error).

I was working on some blitting code today and after profiling it found that I was creating 1000s of new rectangles. I was shocked because I only had 1 or 2 different new Rectangle() calls or I was using the .rect property of BitmapData.
I started commenting out huge swathes of code until I was left with this code in my sprite class:
canvas.bitmapData.copyPixels(_bitmapData, _bitmapData.rect, destination, null, null, true);
I cached the result of _bitmapData.rect at object creation and my thousand of new rectangle calls were suddenly gone from the profiler.
Why the heck would BitmapData.rect create a new rectangle? Is there a way to check the core libraries or something and confirm this is true?

. As far as I could see in the reference manuals, the beginFill() method of the flash.display.Graphics class ends any previous incomplete (i.e., not ending back at the start point) fills by automatically drawing a line to the latest MoveTo() location.But, it seems it also ends any previous incomplete drawing even without fills, by drawing that final line.
But that's ok. The weird part is, even when I draw just one line and begin a fill immediately after that, I guess it tries to complete that line by drawing one more line back to the starting point and the messes up the display with the fill color in the following beginFill() call.
public class MyContainer extends Container
{
public function MyContainer()
{
[code]....
The output is as in the attachment.The first part creates a weird fill along the side of the line till the end of the container object.I even tried a endFill() at line 4, but same result. The only way to prevent this is to explicitly moving to some point as in line 11.

i got an xml fed into flash that creates multiple icons. When icon is clicked it will load an external swf into a container. I am having issues with this part:
Here is question
Why does this work in a test file:
myContainer._lockroot = true;
myContainer.loadMovie("movie.swf");
xml:
myContainer._lockroot = true;
myContainer.loadMovie(this.link);
this.link refers to location of swf file that is related to the icon pressed in xml.Everything works fine and dandy however here is the trouble, they all have different parameters and when loaded into another container thus in a swf they lose some of these. However in my test file when it is simple and straight just 2 lines of code (see above) everything works.

Has anyone seen a Flash Component that creates a slide transition similar to this [URL]. Looks like there is a looping background image and the other slides are loaded above it (hopefully via XML?) and the transition effect maybe in a component???

when I do linkage on a symbol and export it for AS3. Then I edit the symbol, for instance go in and modify anything inside, a shape, etc... the next time I try to publish flash, i get an error multiple constructor definitions found. constructor may not be defined in <Script/> code.I think may be it's because flash does not remember to delete the previous export and creates another one. The only way to resolve this, is to delete the entire symbol and re-create it.

Background: I am trying to create a website that is easily updateable by a non-html savy user. I figure I can load the content of my flash page from a notepad file within the same directory.I would prefer to not make the editor use a FTP program, so I figure the best method is a webpage where the person can log in and type the updated text and have it create a new notepad file and overwrite the old one. I am not sure if this is technically flash or simply a html question, but does anyone know how to go about doing this

I've setup an FLVPlayback 2.5 component with no skin. Then I've added all the UI components and assigned them to the FLVPlayback instance. I'm using a PlayPauseButton, a SeekBar, a MuteButton, a VolumeBar and a FullScreenButton. All of the components had their graphics customized. Extra care was taken not to rename or delete any movieclips.
If I try the custom components by publishing the movie, everything works fine.The problem arises when I dynamically load this SWF into another one. The parent SWF loads the playback controls and instantiates everything and starts the video playerback.
What doesn't work is the SeekBar's and VolumeBar's Handle. It just doesn't appear. If I put a trace() in those MovieClips, they never appear on the console, as if they are never created.

I have got three screenshots below of Flash-based audio players on various websites that draw a waveform of the clip it is going to play and moves along while it is playing and also allowing the user to click on a point on the audio file and it jumps to that point.I have very little Flash knowledge but is this easy to achieve? I would like to just show the Flash file an mp3 and it draws the waveform. I understand this could be quite intensive on CPU so would there be a way of caching the waveform data so it doesn't redraw each time the file is loaded?

I am considering upgrading my copy of Flash Builder to 4.5, and would like a list of the new features in the new version before I commit. I have heard that the ASUnit tests integrate better than previously, and that there are some nice features like quick fixes, is there anything else? Finally, based on your experiences using it, are there any shortcomings to look out for / avoid?

I'm trying to build a workaround for embedding my (downloaded) flash videoplayer. (it's the JWplayer...)
At the moment, when somebody wants to embed the videoplayer they have to include the swf with all the added flashvars (url...). That's messy, and it feels a bit risky... people who know what they are doing can also just remove the plugin and other added data, resolving in me not being able to track pageviews etc.[code]...
Turns out that, when I use file_get_contents on a regular test file, info.php, that responds through a $_GET['var'], the above stated code works, but when I use it on the flashplayer, it doesn't...
As in: the flash file does not seem to be accepting (or responding to) the added header variables...

Im working on a project that has a main swf file associated with the document class. It loads XML that provides the text content for the project, then it loads a swf that contains a font in its library, then it loads the first of several content module swfs. When the font swf has inited, I'm registering its library font with Font.registerFont(), and using it in a TextFormat object. After everything is done, I can add code to the document class to create a text field on the stage of the main swf and format it successfully with the TextFormat object, but when I try to do the same thing inside the loaded content module swf, the text doesn't show up there at all.

When I test a flash file by hitting "ctrl+Enter" it creates a .swf in same directory as my .fla. does the resulting .swf file actually use the selected publish settings of my .fla file? Or when creating an .swf by "ctrl+enter" does it only use a "default" setting?

I am creating a website in flash CS4 and I made a contact form and when I test the site out, I can type and click the submit button, so everything is fine there but it doesn't go to anything. Now I know I need a code to tell the contact form where to go, but I can't find one that works, or I may be doing something wrong. I also have been reading about PHP but I am not sure what that is. I found a site that said to put this code in the actions panel.
