Is there any method in as3 that flash can write file's last modified date.
Its stand alone flash application which had external swf loading. I want to check the last modified date of the swf during the loading.
please suggest any possible methods.
Thanks.
In AIR, there is File class with modificationDate property. But in plain AS3, there's no file concept at all. If you loading swf with Loader, you only get data, but not the attributes of file (and file might not exist at all if loading something by URL.)

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 FLA with some text but the person that will be sending the SWF doesn't have Flash and doesn't know anything about Flash either.
Is there some way to build the FLA so that the text can be changed simply by modifying the SWF somehow? Due to company policy, the SWF cannot read from external files.
We tried programming into the FLA that it read an XML in another server, but that's not allowed. I also cannot send the SWF with another file (ie. an xml file).
Thanks.
Use FLASM or SWFMILL which are free command line assembler/disassembler for swf files. Use any of the one to disassemble your swf. You can open the result file in any of the text editor, find and replace your text and assemble it as swf again. Hope it helps.
It is a strange logic to try to modify a FLA file without Flash. A FLA file is a binary file, you'll need an editor to read it and I'm pretty sure Adobe isn't allowing 3rd party editors legally.
But yes, it's fine to have a dynamic TextField where you can send the parameter and change the data. Please note - you need to send the data. Means it has to come from outside.
What are the options? Well, actually, there are few:
Loading from an external file or getting it from a server side script. You said it's not allowed, let's omit this method.
Read FlashVars. If you publish it within a HTML page, you can actually feed some data via FlashVars. Not only 1 variable, but as many as you want. And it's fine for small strings, but if you plan to pass a text larger than a sentence… Don't do it.
As a funny hack you could try naming your file with the text you want and read the URL of the SWF thus showing it's name and using it as a text data. But don't do it :)^
If you want to try it, you can access the URL with stage.loaderInfo.url, just make sure you have a stage defined - call in the document class or after the display object you're calling from is added to stage.
Use ExternalInterface to communicate with, for example, JavaScript and get the variables from JavaScript. It's actually not so bad, since your text will be tidily stored in a .js file and you can modify it on the run. That of course is a separate file and you need to have the SWF embedded in HTML for that, but it is one of the options you have.
Other than that you could have an external file that will hold the data and embed it in the SWF. Look more on embedding here: http://flashgamedojo.com/wiki/index.php?title=Embedding_XML_in_AS3 . It is about embedding XML data, but you can use the technique for any data, even binary.
Embedding data is a great thing, but you'll need to re-compile each time you make a change in the file, since it isn't loading the file dynamically, but embeds it into to the SWF itself on compile time.
Hope that helps!
JPEXS Decompiler can change text in an SWF pretty easily. It's still actively developed as of 2021.
I want to know how to load external class files(.as files) in actionscript but don't have to know the class file's name. Think of it like loading mods in minecraft with forge mod loader, it doesn't know the main class of the mod's file name, yet it successfully loads the mod. I want to know if something like this is possible in actionscript 3.0 because I feel like making a tower defense game that isn't like the others out there but have it so it can be modded and have mods loaded but of course I have to load the class file without knowing the class file's name.
Note: I don't got access to Adobe Air so I can't use anything that requires Adobe Air.
You want to load a particular .as file AFTER or BEFORE compilation? After the compilation it is hardly possible - the file would not be compiled and therefore it would be useless. Why don't you use a swf or some kind of XML/JSON with settings in that case? Before the compilation you would still need to identify it by it's package name/name.
Basically, you want a plugin management system.
In AS3, it is not possible to "load" a .as file on execution, because it is a (uncompiled) source file. But, it is possible to load another swf and to use the classes within it.
Your process should probably be something like this :
Get a list of the plugins/addons. If you were using AIR, it would have been possible by browsing the content of a folder. Since you're not, you'll probably need to use a listing file (basically, a file that say "Here's the list&path of the plugins you need to load".
Load each swf file
(possibly) call a initialization method for each plugin.
You may wish to look into the way OSMF manages plugins, for example : http://osmf.org/dev/osmf/OtherPDFs/osmf_plugin_dev_guide.pdf
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 am coding an AIR application.
I've got directly a path of a swf file (because it was stored in a xml file).
Do yo know if it is possible to get the ByteArray from this file ?
I know that FileReference do that very well, but this class need a select event. But it isn't my case because I've allready got my path.
Thanks a lot for your answers !
In AIR, you can read/write files directly using flash.filesystem.File and flash.filesystem.FileStream.
See, for example, this article.
however you can load it with URLStream and get a ByteArray with URLStream.readBytes()
