Flex4 - Understanding Flash Packages And Dependencies
Sep 13, 2010
I'm trying to understand how packages and dependencies work with Adobe Flash Builder 4. I've copied an example here and put it in a .as file called DependencyGraph. However I get the error message:
A file found in a source-path must have the same package structure '',
as the definition's package, 'DependencyGraph'.
I understand that the original file has a package name called package flare.apps. What should I change to enable this to run?

I try to load an swf in my flex 4 project using the following line of code: <mx:SWFLoader id="game_swf" source="demo.swf" complete="init()" /> the demo.swf file is another project i created using flex 4. the problem is that when i run the application i see only the loading bar of the demo.swf flash file and nothing else. if i try to load a different swf file (for a example a game i downloaded), it loads just fine.

Specifically, I have a demo of a flash game (sort of super mario style). In it I have two types of weapon - a simple fire and big fireball. I reviewed the code in order to learn flash better [I am very new - since around monday this week].
I saw that the program has a variable that keeps track of the number of uses I have left in each weapon. I tried to review all the places this variable was used but I couldn't find where it affects the drawing onto the screen.
I even tried removing the variable declaration and then testing it - so I may find all references to the variable -- By the way any convinient way of finding all references to a variable/method/class [I am using ADOBE FLASH CS5.5]?
Also, I tried changing the variables starting value to "12" and I noticed that when I test the game, the weapon has 12 uses indeed.
So my problem:1. It seems that this variable is somehow affecting the drawing. Yet, I don't know how it does so since all the code I have found that uses this variable has nothing to do with drawing. It is all, logic, like
if(var <= 0){
var--;
} else{
return false;
}
Where is this influence coming from?get all references to a variable[like in eclipse ctrl+shift+g]?

fix a counter on one of the flash applets he hired someone to make for him. It's AS2 and done in Flash 8.
http:[url]....
It pulls from the current time on the system clock.Essentially it's counting 4 times too slow. I am awful with even reading AS let alone trying to find the equation running this. what I need to edit in the AS to speed this up?

I am trying to understand what is going on in a SWC that I am importing from Flash CS4 into Flex Builder 3. Specifically I am using a SWC supplied by a Designer as the animation for a custom preloader (a subclassed DownloadProgressBar).The issue I am trying to understand is, once the FlexEvent.INIT_COMPLETE is fired, I cleanup by removing the swc by running this [code]though even after I have removed this (which is successful, as I have checked by comparing this.numChildren before and after the call) the key framed animation still continues to run (not visibly). This has been detected by the Designer placing a trace in the time line of the animation (in Flash). Can anyone tell me why is it, that even after I have removed the animation from the subclassed DownloadProgressBar, it still keeps running ? Also, is it standard practice when importing SWCs to manage the cleanup of resources from the Flash side of things (much like releasing memory in obj-c). I find it counter intuitive that removing the child from the Flex side does not stop the animation.

I would like to know how can I install a library packages to a Flash project. I am using Adobe Flash CS4 and the library I'm trying to include is in AS3. The library can be found on [URL].

I've googled a lot trying to find how to properly import and use .swc files in Flash CS 4, tried lots of different methods but none seem to work.
What I've done is:
1. Placed it in my "D:Program Files (x86)AdobeAdobe Flash CS4enConfigurationComponents" folder. It does however not show up in the component inspector.
2. Added it in Publishing Settings as a Library and External Library, still can't seem to use it.
I've also tried adding
"import org.osflash.signals;"
After each method but I receive the error
"1172: Definition org.osflash:signals could not be found."
So what I'm asking for is an easy way to get the .swc package working code-wise with all classes imported etc. The .swc file is as you may have guessed as3signals.

I'm teaching myself actionScript 3.I'm having some difficulty knowing which packages / classes to import from the flash core.I'm still a little shaky on the terminology but I mean these statements at the start of the main AS file.
import flash.display.Sprite;
Are there any good references / cheatsheets that describe what each flash.example.example provides? At least for commonly used packages.

this is the URL of the language reference website I have been using for Flash/AIR: [URL]Is this URL the correct one I should be using when I need to look up a class or method or property or something like that? Because it does not match up with what actually shows up in the Flash IDE when I type an import statement. Most of the packages match up but not all.
For instance, the reference URL has a fl.events package, and so do I locally, but my package seems to be missing lots of classes from it that the reference URL shows. This leads me to believe I don't have the latest SDK's or SWC's or whatever I need installed, whether they be Flash, Flex, Air, etc.Also, I have a few packages locally that don't show up in the reference URL. Things like "flash.debugger" and "flash.trace", they are not my custom classes, not sure where they came from.
Lastly, there are certain AIR classes missing, and I'm sure this is because I don't have the latest AIR SDK installed. I did find it and download it, just not sure how to download it.
1) Is the above URL the one I should be using? If not, is there a better definitive location for Flash/AIR language reference that is updated and always has the latest and greatest info?
2) I have the latest AIR sdk on my desktop, how do I install it? (I'm using Flash CS5 on Mac OSX 10.6)
3) How can I make sure that what I see in that reference URL is what shows up in my code hinting when I type import statements in the Actions Panel? Basically I just want to make sure I am all up to date so everything is showing and working the way it should be. For instance, I am missing a ton of fl classes (containers, controls, core, data, etc.) I want to get these in place so my local copies are synchronized as close as possible with the reference. Documentation doesn't help much when you don't have the tools it tells you to use...
4) Take the fl.ik package for instance. Locally, I have available all the classes in the reference URL that I should, plus a bunch more that aren't there.

OK, heres the thing. Since i cannot stop the code from continuing while i', waiting for amf to send the data, i remember to put a simple rectangle with alpha 0 in front of the stage while waiting for amf to arrive, then remove it.
Since the amf call is done from another class. I don't know how to do this.

I'd like to add a derived property to flex:[code]However, derived won't update when I change a or b.Is there a better (faster) way to make derived update than giving a and b setter methods which invalidate it?added keyword "get".This makes more sense now, I hope.

I'm just getting off the ground as an AS3 programmer and I'm having a lot of trouble getting Flash to recognize my packages. My intention is to keep a code library of all my AS3 source data and have Flash simply go fetch classes from there.
I have set Flash's source path to the following to accommodate my library:
C:Documents and Settings<username>My DocumentsMy DropboxCodeAS3src
However, when I attempt to include a class into a .fla, Flash gives me an error that it can't find the AS class files in the .fla's folder at compile time. So it seems to not be detecting the AS class files in the source path I have set.
Within src, the folders are structured as follows:
srcsivyrmap<AS classes here>
In my AS files themselves, I have written the package and class declarations as follows:
Code:
package sivyr.map {
// Includes
include "flash.display.Sprite"
[code]....
And when I write an include to grab one of these classes, I write it as:
Code:
include "sivyr.map.Grid"

I have several Flex applications in a project, and I would like to know if there's a way to get a list of the classes (and ideally, other assets) that are being compiled into each one. I want an easy way of making sure I've kept things separate and there aren't unnecessary dependencies. Any ideas? I'm running Flash Builder 4.

I'm trying to use the MovieClipLoader class to load external swfs into my main movie. A problem occurs when the external swf relies on or loads other external files. The external swf acts as if it's running in the same directory as the main swf and expects files to be located relative to that.
For example:
main_movie/main.swf
other_path/external.swf
[Code]......
This seems to be similar to having the base parameter set improperly in the html, but I haven't been able to find a way to set this when loading an swf dynamically with MovieClipLoader.

I am working on a system that will allow you to annotate classes with information such as dependencies and the scope of it:
Code:
[Singleton]
[Requires (ClassName1, ClassName2)]
class RenderSystem()
[code]....
This class is a singleton that requires ClassName1:Class, ClassName2:Class. If class 1 or 2 are singletons then it will inject a singleton and if not it will create a new object for it.Memory Manager instantiate method looks like this
Code:
/**
* Instantiate an object
* @param type (Class) The type of object to create
[code]....
For the most part it all works but when mxmc compiles the project it drops unused classes. Since they are dynamically allocated this means that at runtime most of the library isn't there.

clarify the different logical instantiations of objects in actionscript?So far it seems there are 3 layers of instantiations, for lack of a better term.The first one is declaring a variable/type.Next is instantiating that variable with something solid in the code, like a method or function? Is this just a way to glue things together? Then after that you instantiate it on the stage, is this something you have to do explicitly, or is it a side effect? Is this "3 layer" concept the correct way of looking at it, kind of like the MVC for flash app logic?

I'm looking for a way to collect the file dependencies from Flex ActionScript and MXML files. I was hoping that mxmlc could spit them out (like gcc's -M option), but its option list doesn't seem to have anything relevant. I could write a parser, but would prefer not to reinvent the wheel if it has already been done, particularly given the two very different languages involved. In particular, star imports and in-package implicit imports could be troublesome.

I have a large Flex project with two Applications in it. A lot of code is shared between these Applications. However, the smaller of the Applications does not require much of the code that the larger one does. I'm trying to ensure that code that isn't required by the smaller application isn't getting compiled into it.

So I have a project comprised of multiple modules and I'm trying to work out the best way to compile, with minimal code duplication.
I have a core Framework SWF and a number of sub applications which are independent of core. In addition I have a series of common library SWCS which core and subapps are dependant on.
I'm not sure the best way to compile this project so that each module does not need to include the libraries as this would duplicate code. Would love some advice!
I started out with using external-library-path for compilation, but something is going to have to include the common libraries.

I'm used to building applications using pure AS3. I always pass dependencies into the constructor of classes I make, but this method seems to not work out well for Flex MXML views. It seems like I should define setters on the MXML class, which map to attributes in the tag/class instantiation. But using this method I cannot specify which properties are required and in what order I expect them etc. What is the preferred method to give a Flex view it's dependencies?

I'm using robot legs, I've got a bunch of ServiceResponses that extends a base class and have a dependency on a Parser, IParser. I need to wire in a parser specific to the subclass. Here's an example: ModuleConfigResponse extends SimpleServiceResponse and implements IServiceResponse.
The initial part is easy to wire in the context, here's an example:
injector.mapClass(IServiceResponse, ModuleConfigResponse);
injector.mapClass(IServiceResponse, SimpleServiceResponse, "roomconfig");
..etc
Each Response uses a parser that is used by the baseclass:
injector.mapValue(IParser, ModuleConfigParser, "moduleconfig");
injector.mapValue(IParser, RoomConfigParser, "roomconfig");
The question is how to tie these together. The base class could have:
[Inject]
public var parser : IParser
But I can't define the type ahead of time. Im wondering if there a nice way of wiring this in the context. For the moment I've decided to wire this up by instanciating responses in a ResponseFactory instead so that I pay pass the parser manually in the constructor.
injector.mapValue(IParser, ModuleConfigParser, "moduleconfig");

Friends, I am developing a control panel for a web hosting company, I am considering using Adobe Flex 4 (Adobe Flash Builder), but I'm afraid that the staff are no longer using more flash in computers, especially with the growth of ipad, iphone without flash.
This panel will be used by enterprise customers to manage their products.
Do you think that the flash actually has a future? think it is reliable to use flash in such an application?
