Actionscript 3 :: Use Timeline Scripting On Embedded SWF Assets W/ The Flex SDK?
Sep 11, 2009
I've embedded a SWF into a class using this syntax above my class definition:
[Embed (source='/../assets/MyMovieClips.swf', symbol='SpecialMovieClip')]
public class SpecialMovieClip extends MovieClip
The MovieClip asset seems linked with my class okay, and instantiates along with it, and is visible, but:
I can't access instances placed on stage within that clip. The timeline scripting seems non-functional.
Is this the drawback of embedding SWF files at compile-time with the Flex SDK? So, maybe I should just go back to compiling with the Flash IDE if I want timeline scripting or instances positioned on-stage?

I have a Flex project in which I am embedding a Flash SWF containing an image viewer. The SWF file I'm embedding is supplemented by an XML file, which contains a list of images to show, and an images folder containing the images. The problem I'm running into is that the embedded SWF file is unable to load the pictures. I am able to see the forward/backward navigation buttons, but there are no loaded images. When I view the SWF file outside of the Flex project it works fine. Is this because Flex isn't allowing the SWF to reach outside and access other project assets?
Here's my code for embedding the SWF:
<mx:Script>
<![CDATA[
import mx.controls.Image;
import mx.events.CloseEvent;
import mx.managers.PopUpManager;
[Code] .....

I was trying to further reduce the filesize of a SWF file by optimizing the embedded PNG graphics (using ImageOptim tool). To my surprise, this didn't yield any effect, so I created two test Images:
Original (433883 bytes)
Optimized (273723 bytes)
When embedding either of these assets in a simple ActionScript project, the compiled SWF is ~274kb in size. Which raises the question: Does Flex optimize embedded PNG assets during compile-time? If yes, is there some documentation about the optimization going on? It can't be because of the SWF compression alone, because zipping the images doesn't reduce filesize at all.
Here's the Code for completeness:
package {
import flash.display.Sprite;
public class SizeTest extends Sprite {
[Embed("/assets/original.png")]
private var ImageAsset:Class;
public function SizeTest(){
}}}

When I build the project from within flexbuilder, it compiles it fine and does not throw any errors.

I used to be able to create distributable components in AS2 (swc files) containing class code and assets (movieclips). And it used to be really easy.Now I am struggling with Flash CS4 and AS3 and all my attempts were frustrating, as no matter what I try it simply doesn't work. I am starting to assume that maybe it is not possible anymore to do in AS3? Maybe this kind of thing is deprecated in Flash now???
Let's see what I have tried:
1) I started with a new FLA and named it 'MyComponent.FLA'. Then I drawed a green square, converted it to a mc and named it as 'MySquare'. Then I tagged 'Export for ActionScript' and 'Export in Frame 1'. Then I named the class as 'MySquare' and set the base class to 'flash.display.MovieClip'. This is my asset (a green square movieclip).
2) Created an empty movieclip and dragged the asset within it. Then I named it as 'MyComponent'. Then I tagged 'Export for ActionScript' and 'Export in Frame 1'. Then I named the class as 'MyComponent' and set the base class to 'flash.display.MovieClip'.
3) Right-clicked it in the library and chose 'Component Definition'. Then in class field I typed 'MyComponent' and tagged 'Display in Components Panel'.
4) Crated a new AS file, called it 'MyComponent.AS' and typed the following code:
Code:
package {
import flash.display.MovieClip;
public class MyComponent extends MovieClip
[code]....
5) Back to 'MyComponent.FLA', right-clicked the 'MyComponent' object in the library and chose 'Export SWC file'. That was ok, no warnings, no errors. Then I just copied this new SWC to my components folder.
6) Created a new FLA and named it 'test.FLA'.
7) Reloaded the components panel, and my new component showed up. Then I dragged it into library.
8) Then I type the following code:
Code:
var test:MyComponent = new MyComponent();
trace (test.visible)
9) I ran the new app and it was ok, no errors and no warnings. The trace statement spit out 'true' what means that the new class is really there, but... I cannot see the green square. But when I click onto the 'MyComponent' in the library, the preview shows up the green square, what means that it IS THERE in the component. So, why it doesn't show up in the stage after the class be intantiated?

I have a site that contains a page with a fancybox pop up which contains a .swf.This swf loads a sound file and a thumbnail (mp3 and jpeg). When I view this by double clicking the swf it works fine, when I navigate directly to the swf in the browser it works fine, however when I try to view the embedded swf it does not load the jpeg or the sound file. I have another page which does the exact same thing except it loads a different swf which only loads a video file and this works perfectly.
AS3 code :
Code:
package www.elementalstudios.co.za {
import flash.display.Sprite;[code].....
Where the $theInner is a javascript variable that is used to set the innerHTML value of the div that I want to have containing the swf and $jUrlArray is an array of filepaths to various folders containing different sound files and thumbnails (each folder also contains the swf).The thinking is that the swf looks for the files as "sound.mp3" so the swf would assume that file is in the same folder it is in, therefore I'm only loading the swf from the different folders.

I would like to be able to access all the components of say a Flash image gallery on someone else's site. I want to be able to find the images, image coordinates, action script code, audio files, video, etc. I do not want to manipulate these elements, I just want to view them and their related information.

I'm creating an AIR 3.0 app.
For a lot of my graphical assets I'm using the Flex embed metadata to embed bitmap objects as Classes and then instantiating them.
The problem is that it seems these never get garbage collected. I haven't found much info online but I've seen a couple of posts that seem to confirm this.
Anytime one of my classes gets instantiated that has these embedded assets, they always create new instances of the Bitmaps and BitmapDatas rather than reusing what's already in memory. This is a huge problem for memory. And I can't find any way of de-referenciong them or getting them to leave memory.
So the only solution I can think is to just load the graphics from disk rather than using the embed tag. But I'd rather not do this seeing as how when the app is packaged and installed, all of those graphcial assets will be on the end users computer rather than contained within the SWF.

Is there a way to execute code (like a preloader) before loading the embedded assets? I'm using the [embed] tag with CS5, and I'd like to avoid using an external preloader.

I am a main timeline, with a movie clip that I want to loop infinitly, until a button is clicked, once the button is clicked I want it to stop the movie clip timeline, once the button is clicked again I want it to start the movie clip timeline again.
I am not the greatest actionscripter, I understand it I just have a bit of trouble writing the syntax myself.

I have a flash movie which has got 5 scenes and from scene 2 onwards i am using sound. In scene 1 I have made a prelaoder. My problem is that it starts loading sounding in scene 1 frame 1. Is there any way by which the sound starts prelaoding in frame 2.
Problem 2.I am using same sound in different scenes timeline. How can we by flash scripting call the sound from the library at the timeline.I am using F 5.

I have an animation that is timeline based. The file size is around 900kb for the entire project, as it has numerous images at different stages.
How does flash determine when to start playing the movie? Is it based on a percentage of loaded size or does it load assets as it moves along?

I want an air application to be able to update the assets it uses, but minimizing the download needed, so only downloading files added since it last updated.I'm thinking this would include a server portion which would zip the needed files based on a version number? Has anyone implemented anything similar / got any thoughts on the best approach to building this sort of system?

I may not have the correct terminology and such, but I have a simple symbol that plays, and then I have a timeline within that symbol that I want to play right after that. I named the embedded timeline/frame "trailer" so I used the action
gotoAndPlay("trailer");
this works if the named frame is in the main timeline, but it doesn't seem to be able to access the timeline within the symbol. Is there a different command I could use? Or am I doing something wrong?

I am trying to embedded an flv into a flash movie timeline that runs at 12fps.My source avi is 60 seconds in duration. However using cs3 video encoder with the frame rate set to 12 fps results in an flv that uses up 1440 frames of my timeline.In fact any frame rate selected always results in an flv of this frame length? Assuming that I need the flv to be 720 frames total (60 seconds * 12 frames), and not twice that duration as that would still have to be played at 24 fps. I undertand that there is a relationship to the original fps the movie was shot in (in this case 24fps) but will/does the encoder not produce an flv with the frame rate altered to match my timeline fps? or do you basically have to use a camera that shoots the original avi at 12fpsto get it to play in 12 fps timeline??

Is there any way we can stop the sound embeded in timeline directly?
We have an application that load SWF dynamically. These external SWF are not created by our company and other company has embed the sound in timeline. without use of any actionscript or anything.
Now we need to provide the MUTE option for our user, is there any way We can simply disable all kind of sound in any mode from our ActionScript code.

I've been given FLAs that contain audio embedded within the timeline. It's been a long while since I've had to deal with audio in this manner and I'm running into a problem.
The basic setup is this:
- There are 3 movie clips within the FLA
- Each movie clip contains embedded audio within the timeline
- The audio plays as soon as each movie clip begins
Here's my issue:
On the main timeline, there is a 'back' button which allows the user to move to the previous movie clip.
When the user clicks this button, it does move back to the previous movie clip; however, the sound does not stop which results in 2 audio files playing at the same time.
If I were calling the sound utilizing SoundMixer/SoundChannel, I know how to ensure the audio stops, but since the audio is embedded within the timeline, I'm not quite sure the best way to make sure the audio stops when the preceding movie clip is called.

I am having trouble with an embedded audio clip. (embedded in the timeline) First, the reason for embedding.... I need the audio (voice over) to correspond to the on Stage animations, and have words and animations appear when certain keywords are spoken. Second, here is what I have tried...
1) I have tried to embed the audio clip directly on the timeline. The audio file I am using is an MP3 created out of Garage Band. (Mac audio program) When I embed the clip, and publish a preview, it nearly crashes Flash Player. The audio continues to play, but all on screen animations are severely slowed and choppy. And I must force quit Flash Player to close it. Plus it is nearly maxing out my CPU during playback.
2) I removed the audio clip from the timeline, and decided to try AS3 to import and control playback of the audio clip. This seemed to work fine, no slowdown, less CPU usage, and on screen animations seemed to play normally. However, it is nearly impossible to sync the audio and on Stage animations with an externally loaded audio clip. (timing is always different depending on computer and internet speed.)

I have a website with a flex application. The flex application has no user input - except for clicks for navigation. The website also uses no scripting language - i.e. no php, asp, jsp or cfm.
The website just consists of one page which contains the flash file for the flex application. The source code of this page is here: [URL]
I have been advised (by a software program used by my client) that this website is vulnerable to a reflective type XSS attack and have been advised to 'sanitize' all user input.
respect to XSS and would respectfully like to ask that AFAIK there is no user input. What should I sanitize and how?

i am creating a survey with say 7 questions. each question has the same MovieClip symbol each with a different instance name, like q1, q2, ... q7.
the MovieClip symbol has 5 static texts and 5 SimpleButtons. i have some code in that symbol to make sure that only a single button has the "on" or "checked" state to show that that one is chosen. this works great.
my question is, how do i communicate each user choice with the main timeline after the user hits the "submit" button? or, how do i have code under the "submit" mousedown event that can iterate through the 7 symbols to query each one and see which of the 5 SimpleButtons is "checked" or "on". this iteration will then create a list of responses for all 7 questions.
ultimately, i will have flash concatenate a GET POST string that will send the survey results to a web server.

I have a swf that has embedded audio on the swf's timeline which is set to Stream. This swf is then loaded into my main flash timeline via the loader class. I have a button coded as a toggle switch that pauses the loaded swf via the stop() and play() command. This works fine. The issue is that when the swf is paused (stop()), the audio is longer heard, but it continues to play. When I press my toggle switch again, the swf begins to play exactly where it was paused and the audio is now heard, but the issue is that the streaming audio is now out of sync since the swf timeline paused, but the audio continued to play. Is it possible to stop or pause the embedded audio on the timeline? I've tried looking at the SoundMixer static class, but this doesn't seem to help. I can use SoundMixer.stopAll(), but there's no way to start the audio again.

I am developing a flash web site using ACTIONSCRIPT 3. There is a menu of small icons that, when one of them is clicked, the program loads the correspondent SWF into a loader and then presents it in a "virtual screen" ( a rectangular area ) in the web page. The problem is that some of these child SWFs have an embedded background sound and I DO NOT KNOW how to mute them from the main SWF when a user decides to do so by clicking a "mute" button.
Each SWF embedded sound has its own layer in its timeline and is set as Sync: Event, Repeat:1.

I'm attempting to compile my Flex project with an ANT build script.One of my MXML components references an external XML data file, like this:
<mx:XML id="treeData" source="assets/data/help.xml" />
When I build the project using Flex Builder, it compiles fine. However, when I try to compile it using ANT, I get the following error:
Error: Problem finding external XML: assets/data/help.xml
How come ANT isn't finding the XML file? Apparently it knows the source path otherwise it would not have found the component to begin with. I added the source path to the target anyway, but it doesn't seem to have made any difference:
<source-path path-element="${SRC}" />

My main.swf loads symbols from other swfs at runtime. If I keep all the swfs(main and others)on my server, things work fine. But if I keep all of them on a CDN, one particular symbol won't display occassionally. With flash tracer plugin for firefox I am able to see that all the symbols have been loaded and their z-indices are as they should be.
