I've embedded a MovieClip symbol with the [Embed] syntax into my AS3 project, which I'm compiling with the Flex 3 SDK. That MovieClip has instances of other clips within it that are placed on stage with instance names. I can't just access them by instance name like I would if I were compiling with the Flash IDE. How can I reference them?
View 1 RepliesI 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(){
}}}
I cannot get embed fonts working Everywhere I look it says to do it like I am doing it below, but it doesn't work. I am using FlashDevlop with Flex compiler. There are no error messages. I have tried taking everything out of the Embed directive and adding it in one by one, but no affect.
When I use the system font, it works.
When I use the embedded fonts without setting embedFonts to true, I get TimesRoman.
When I use embedded font with embedFonts to true, I get nothing.
ActionScript Code:
package fontManager{
import flash.text.TextField;
import flash.text.TextFormat;
import flash.display.Sprite;
import flash.events.Event;
public class Main extends Sprite

Our Flash web-based applications play lots of audio for narration and sound-effects. Some of our customers have firewall rules that block downloading of MP3 and other audio files. So, we need to wrap those MP3 files in SWFs. In the past, I've written JSFL scripts that automate the Flash IDE and walk through a complicated, fragile set of steps to embed MP3 files into FLAs and then publish those to SWFs. Now, Flex SDK provides the mxmlc compiler. I've mixed ANT into our workflow, and command-line and automated builds have been a joy. So, I want to make transcoding or wrapping of MP3s part of our build process. I've found Embedding Asset at Compile time in Pure AS3, but this will require that I write a script to generate a wrapper class AS file. Is there a cleaner way to wrap or transcode MP3 files into SWFs?
View 1 RepliesI'm using Flash CS5. I have some instances on my stage declared in the main class and I want to attach some events to them, however at the time of the main class constructor, these are declared as null.
What's the best practice for accessing stage instances? Is there an event listener I could add that will tell me when the stage instance properties have been populated?
Simple example:
public class bleepBloop extends MovieClip {
public var productName:TLFTextField;
public function bleepBloop() {
trace( productName ); // Here it is null
}
}
However, when I access productName later, it's defined.

Its stated in adobe site that the Flash Builder 4 compiler is indeed 25% more performing than the previous Flex Builder 3 compiler.
How can I confirm that?
For example if I make a simple application on Fx3 and the same on Fx4, then how would I compare the compiler performance using my project?
There are some classes that were taken out of the 4.0 flex sdk and I would like to know how to configure my compiler to use both sdk's, if it is even possible.

I'm trying to write a compiler argument for FDT to force the inclusion of one of my SWCs. It looks kind of like this (App name changed, but the real one also contains mixed case and a space): -include-libraries "C:WorkspacesMy Applibssite.swc" Problem is that the compiler claims it is unable to open this file. Is there a problem maybe with using a full path like this? Ideally I would prefer to use a token to represent the project folder, something like -include-libraries "${project}/libs/site.swc", but I don't seem able to find a token list in the docs.
View 1 RepliesAfter changing the Flex SDK to 3.6 (from 4.5.1) so as to target Flash player 9.0.124, the project no longer compiles, producing spurious errors such as XML does not have matching begin and end tags leading me to believe that the compilation process is 'borked'.
This is a pure AS project, and so should have no dependency on the Flex SDK, howver, it seeems to be inextricably linked to the Flex 4.x SDK and Flash Player 10+. I have tried swf-version and -target-player-version in the compiler arguments, but there is still something I am missing to get this to compile for Flash player 9.

I have a project that I need to develop some Java code for. The project is using Flash and BlazeDS. For the initial build of the project, an Ant script is run that eventually runs what I believe is the Flex compiler (the sdk attribute points to a FlashBuilder 4 sdk/4.1.0 directory).
View 1 RepliesWhy do I need to do add extra namespace declarations (below) in a Flex 4.1 "MX only component set" project to get it to compile within Flash Builder? (It says mx:LineChart cannot be resolved when a chart is added via Design View, and datavisualization.swc is referenced.)
Is there a way I can get this to compile without adding these special xmlns:charts, xmlns:series and chartClasses to the declaration? (If I just leave the default namespaces and use mx:SomeChartComponent, it doesn't compile.)

I'd like to gain read only access to the following parameters of embedded Flash videos located on sites that I do not own through my own custom browser extension/add-on:
Time location of playback head (so I can display the current time in the browser extension via HTML5/JavaScript) Frames (so I can make capture them to an image file, save it and display image in browser extension) Original Dimensions in pixels (so I can display the original video dimensions via JS/HTML5 in browser extension)
Is this possible by using Javascript and HTML5 from a browser extension?
Would I have to use something like the SWFObject Javascript API [URL]
I consider myself quite effiicient at actionscripting (ok not a guru) to have such problems by mistake.Anyway, my problem is that i am trying to access an MC through a buttons on rollover & rollout actions. So, the button and the MC are BOTH on the same timeline and stage, on the SAME movie clip, and they both have keyframes at the same frame. However, whenever i try to use something like

I have seen a few blog entries on this and have had a discussion or two with my team mates but I would like to see what the stack overflow community thinks.
So why does the Adobe Alchemy Tool create so much faster running flash byte code than the flex compiler?
Also, when will the flex compiler be able to make similar performance gains? Will it require programmer specific use of special Array's or something of that nature to get the same performance?

I need to access the main stage to add a mouse up event listener.
Is there a way to get an instance reference to the document class to call a method of it from the stage's timeline?I see that here's a possible solution: using a singletonOther solution I though of is using stage.getChildAt( 0 ) but it's not very nice.Is there an 'official' instance reference? because the document class is obviously instantiated at startup, but is that instance accessible in any way without having to use a custom solution like the ones mentioned?

View 3 RepliesI am following a code example in a book and have the final fla and as files, so I know the project works when fully coded.In the book, it tells me I can test the movie to make sure that it is working so far. When I do that, I get the error 1120: Access of undefined property.
The "property" is a component instance. If I take the example completed code and remove everything up to the point I am at, I receive the same errors, so I know it's not a spelling/syntax mistake.I have a feeling it is the Compiler in Strict Mode. But, when I change it to Standard Mode, then I get error 5001: The name of package 'com.foundastionAS3.ch12' does not reflect the location of this file. etc.
note:: attached is a file of the compiler when it gives me multiple 1120s.
Does MXML get compiled down to as3 and then converted to flash bytecode? Also, is there a significant performance penalty to compiling mxml vs compiling as3?
View 3 RepliesI am completely new to the whole FlashDevelop/Flash/etc toolchain, but wanted to do some experimenting. I installed FlashDevelop and Flex SDK on my laptop, and thinks worked out just fine, except for one thing: the compiler messages are localized! Messages like "gebruik van een niet-gedefinieerde eigenschap" (Dutch.. sort of) are limiting my productivity. I don't recognize them because they look nothing like what I'm used to in any other programming environment, as a proper sentence they make even less sense than English error messages, and I certainly can't google them properly. Now I've already seen there are a couple of xml files and java/mxmlc/fcsh/etc configs I can tweak, but nothing so far helped.

I have couple of questions about AS3 variables handling by AVM/compiler/scope .1. This code in Flash will throw an error:
[Code]...
but it won`t throw an error in Flex (only warning in Editor). Why?.2. How Flash sees variables in loops? Apparently this:
[Code]....
isn`t equal to just: var mc:MovieClip=new MovieClip(); var mc:MovieClip=new MovieClip(); because it will throw an error again as earlier in Flash, but in Flex in function not? Is Flash changing somehow my loop before compilation?
.3. Where in a class in equivalent to timeline in Flash - where in class I would put code which I put normally on timeline (I assume it is not constructor because of what I have written earlier, or maybe it`s a matter of Flash/Flex compiler)?

Are there any workarounds to get the Flex compiler to work with a 64bit JRE? If I use an MXMLC task in an Ant buildfile in Eclipse it works fine but if I try to use MXMLC from the command line (or try the Run... command from FDT in Eclipse) it fails, telling me ...
"Error loading: C:Program FilesJavajrrt-1.6.0jreinjrockitjvm.dll"
(this is with a 64bit JRockit runtime but that shouldn't matter).
The Flex application below generates the compiler warning: Data binding will not be able to detect assignments to 'dp'. This seems correct since the variable 'dp' is not a bindable property (there is no [Bindable] metadata tag). I have added a button which appends items to the back of 'dp' when it is clicked. Although the compiler warns me that I will not see changes to 'dp', the list shows the new item every time the button is clicked! I do not understand why I can see new items appear in the list. Can someone explain why this still works although 'dp' is not bindable?

I think the eclipse e4 SWT project doesn't compile to ABC (ActionScript Byte Code) directly, but first converts Java to AS3 and then the Flex compilter does the rest.Could it be that no one yet wrote a simple Java / Python / Scala AVM2 compiler that can be used as an alternative to the proprietary Adobe Flash Builder (formerly Flex Builder)?I don't mind paying Adobe for a fine producy, but writing Java in eclipse is so much faster and convinent than the half baked adobe plugin suite. are there really no efforts other than haXe?
