Given is an online swf on Hubworld's site, which loads two configuration XMLs into an .swf file, then displays a game. A copy of the Flash with the two configuration files can be found here. (http://db.tt/zYT9Owg5). If unzipped into a folder, it loads the two XML files and displays everything correctly. The problem is, how to take it apart?
I tried decompiling the file, but it only shows up as a (mostly) empty file with a single symbol and a few misc tags inside it, despite the file itself containing several hundreds of vectors. (http://i.imgur.com/si6gq.png). I severly doubt that any sort of encryption or obfuscation is present, since it's a children's game and I took apart many others without a problem. How could I retrieve the said files from the container?
The swf contains another swf embedded as a ByteArray. I'm not sure why, but this is probably an obfuscation technique.
You can view the actual assets by running the swf in SWFWire Debugger. This application will dump the swf that is loaded from the ByteArray into the same folder as fashion.swf. You can then load this in your decompiler, or SWFWire Inspector if you just want to view the assets.

So I have a .SWF file, there are several people I know calling the .SWF file directly from my server onto their page.
I need to do some maintenance on the .SWF and wanted to replace the current SWF file with one that just says "under maintenance". I know there are ways to do it via html/php but I do not have access to the html/php code the other people are using on their servers to call my .swf file.
I plan to name the .swf file with the same exact name, so it doesn't break for the other people linking to my .swf file from their website.. but my concern is that their users will show the a cached version of the .swf file instead of my new .swf file.
Is there actionscript or anything I can put in the .swf so that it prevents the users on the other site from using a cached version?
Thank you.
If people are loading the SWF file directly, the only thing you can do is replace it by a polite loader.
This new structure would be:
a new SWF with the same new from the previous and rename the original one.
this new "main" file would load the original one appending new Date().getTime() to the end of the file name.
loader.load(new URLRequest('myOriginal.swf?k='+new Date().getTime()));
That should work.
You can reduce the caching period for .swf files via an .htaccess rule. For your purposes, reduce it to 1 hour or less. That will force all the newly requested swf files to be redownloaded.
When you're finished with maintenance, remove the rule or increase the caching period.
It seems as though every actionscript file (not custom ones) is automatically included when coding in the timeline's actions, so I'm wondering if it's necessary to import the files through the code. Are there any advantages? Can I prevent flash from importing every file to reduce the size of my flash application (SWF)?.
For example, I don't need to import MovieClip to use the MovieClip class in timeline actions.
You can indeed load external assets, that is, anything of SWF, MP3, WAV, JPG or any byte sequence you have a decoder for, then parse it via code, then use in your Flash app. The advantages are flexibility, for example, if a user has all sounds turned off, you are free to not load large music for him thus saving him some traffic - this might be crucial for some people out there. There are also disadvantages, because the files (assets) in SWF are available from the start of your app, and because the connection can get lost at any moment, you might not receive your external files in time for the app to use, or not receive them at all.
Not importing in order to reduce the SWF size? I'd say reduce the size or quality of those assets instead. The actual mess with Loaders is something you should avoid unless you have dynamic downloadable content (some extra levels' metadata maybe) which you plan to generate on a timely basis in order to attract longer attention to your app.
In short, all static content is better embedded, all dynamic content should be loaded afterwards.
Compiling FLA file doesn't embed every AS file in the resulting SWF. My test directory structure.
Work Directory
file.fla
ClassA.as
ClassB.as
The code on my timeline.
var a:ClassA = new ClassA();
The resulting SWF only contain the ClassA.
For multiple SWF files with code, every SWF embed the class. It's your job to tell the compiler.
If you are using FLEXSDK, you can look to these parameters.
-link-report file.xml : Generate a file containing all AS file include at compilation.
-load-externs file.xml : Exclude all class containt in the file.
If you are using Adobe Flash exclude class article
I have a swf file (game file) which reads the content of external text file which I have created. This swf file will not be used in any browser. It's for windows only. I was wondering if I can delete or update that text file after I read it's content without using air.
Your question isn't very clear, I'm not sure what exactly you wanted to know. But if I understood you correctly:
You cannot delete files from the filesystem in the through Flash Player, but you can however delete it from SWF file's memory.
Deleting from the file system (basically like putting into trash) is something that only AIR can help you with.
Deleting from memory would mean to remove all the listeners from URLLoader or Loader object instance and setting it to null.
You cannot write the file with Flash player to edit it's content (update), but you can load it again and check if anything changed in that file's content that also would be considered as updating.
Hope that answers your question.
you cant do that without air. but you can use an external application using fscommand().
or you can use Multimedia Zinc
I have a document class in my project and after I update it and put it on server the flash player loads the old version. It doesn't save in the cache memory which I clean every time I test the results, but seems to work when I change the name and modify the swf's doc class. Any idea how I could get around this? My document class is in the same folder the swf is, if it matters.
You must recompile your .swf locally and reupload that to your server. Any classes (.as files) are compiled into the .swf and not loaded by the .swf In fact, there's no reason to put any source code on a server, just like there's no reason to upload a .fla file.
I have a SWF file I created using Adobe Flex and I cannot seem to properly embed it inside an HTML page. If I take another SWF file and use it instead, it works all the time. My SWF file is pretty big (1 MB) while the other one is tiny (25 KB). However, I can wait 5-10 minutes and the server connection is super fast and it still will never load.
Is there something I need to do to the SWF to have it start up properly? My SWF almost never runs.
Thoughts?
I see two posible problems here:
Browser is not able to download your SWF file
You can check it if you add SWF file name directly into browser URL. For example http://your_domain/page/test.swf. If you will get "Not Found" error then your file was uploaded incorrectly
You did something wrong when embeding SWF file into HTML
If you have a working file then you can try to overwrite it with new one (leave original file name). Problem can be in sigle symbol in new file name, even letter case should match.
Or you can try using swfobject library for embeding flash into html
