[Flashcoders] AS2 EventDispatcher problem
hi guys - i could really use some help here
I have a swf, 'swf', that has a movieclip called 'clip' placed on
stage that uses the following class in it's linkage
all of this is loaded into another swf with moviecliploader
[code]
import com.receptacledesign.events.EventClip
class com.Clip extends EventClip
{
public function Lex()
{
super();
trace(Lex is here);
trace(_root._currentframe);
}
public function fireEvent(evt:String):Void
{
trace(evt);
dispatchEvent({target:this, type:EventClip.FINISHED});
}
}
[/code]
The fireEvent method of Clip is called from the timeline of the clip
once the onLoadInit event fires, i'm trying to listen to it within the
main class using the following line:
[code]
swf.clip.addEventListener(EventClip.FINISHED, Delegate.create(this,
animationFinished));
[/code]
but the event never gets picked up (i have a trace in the
animationFinished method to see if it's working) even tho the
fireEvent method traces correctly (with the trace(evt));
is it possible to do what i'm trying to do or have i done something
stupid?
thanks

Re: [Flashcoders] AS2 EventDispatcher problem
Where's the code for EventClip? Without that, we can't be much help. :-)
Also - does trace(swf.clip) return something sensible on the timeline?
(Just so you know you're targeting the right object when using
addEventListener)

[Flashcoders] sizing an arbitrary loaded swf
I'm using AS3. After loading in an arbitrary swf using the Loader class, getRect and getBounds don't necessarily reveal the internally defined boundaries of the loaded swf, rather they seem to return the boundaries of the stuff inside the loaded swf which can be either smaller or larger than the internally defined boundaries. Am I missing something? I want to load in a swf, create a mask around it so that only the stuff that is supposed to show is shown, and then scale it to fit a target area. This should be easy, right?

Re: [Flashcoders] sizing an arbitrary loaded swf
No, this is not easy. Unfortunately the data that defines the stage size is not directly available in AS code. I believe it is only in the swf file's header, so you would actually have to do a lot of work to figure out what size the swf should be masked at.

Re: [Flashcoders] sizing an arbitrary loaded swf
Thanks Steve. I thought maybe I was onto something with the LoaderInfo classes width and height props that return the nominal w and h, but this information doesn't seem to jive with what I'm observing. I'm considering using BitmapData class to physically find the visible boarders of loaded swf, but I guess this assumes that there aren't any stray bits outside of the main image.

If I understand the concept, I think this would require cross-domain policy to be turned on for my domain. What we're trying to do here is load in an arbitrary swf hosted on an arbitrary domain.

[Flashcoders] how to uncompress a compressed bytearray with PHP
I am sending a compressed bytearray to PHP: var XMLOut:ByteArray = new ByteArray(); XMLOut.writeUTFBytes(rootitem1just an example/item1/root); XMLOut.compress(); . cut . The data is POSTed (with URLLoader in var XMLString) to mydomain.com/save.php: ?php $XMLString = gzuncompress($_POST[XMLString ]); $handle = fopen(content/test.xml, w+b); fwrite($handle, $ XMLString); fclose($handle); ? The result of this is that test.xml is being created but without any content. (BTW: If I leave out the compression/decompression part then the file is created with the expected content) Should this actually work with gzuncompress and if so why might it be failing here? Or should the uncompressioning be handled differently? ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] sizing an arbitrary loaded swf
As someone already said, you can grab that data from the swf header.
I've done this in C# / .NET and I've just wrote a quick and dirty port of
the header parsing part to AS 3.0. Probably there's room for optimization
but as a proof of concept I think it's ok. Also, the code could use some
clean-up and the SwfRect part is based on an API different from ByteArray,
so basically I was not using readByte() and such but calculating offsets by
hand, which could be avoided.
So, the flow would be:
1) Load the swf as binary
2) Parse the headers to get the info you're looking for
3) Use the loadBytes method from the Loader class to load the swf from the
bytearray you already have loaded.
I'm pasting the sample code in this email, but you could see it more nicely
formatted here:

Re: [Flashcoders] how to uncompress a compressed bytearray with PHP
I see a couple of spots for problems in what you are doing. When you're compressing the data, you are basically transforming text strings to binary. I mean, text is binary data, but generally strings cannot contain NUL characters (that is a 0 value), because that's traditionally reserved to mark the end of the string. On the other hand, 0 is a perfectly legal value in a binary context (so to speak) and I think you'll probably get some 0's in the compressed data (or at least, I'm not sure if you could be sure you won't, under any circumstance). So, when you're posting data (except you post as binary), NULs will be a problem, because the data (the string) will be truncated. From the php side, I think you should use the gzinflate function, as the ByteArray class uses inflate / deflate (from zlib). I haven't used it in php, just found it in the manual: http://ar.php.net/manual/en/function.gzinflate.php The signature of the function says it takes a string, so should probably check what happens if you have embbeded NULs here too... (my guess is that php will also truncate the data). You could try to post the data as binary and see if it works, but I'd first check that the uncompressing is working on the php side. A quick and dirty idea: you could check this by dumping the compressed ByteArray in the Flash IDE, for instance, to the trace output, in the form of a php assignment. I.e, printing something like $data = chr(someNumber) . chr(someOtherNumber) . chr(someOtherNumber); Then paste that in your php file and try to get the uncompressed data hardcoding the generated php assignment. If you get that right, then you know the only remaining problem is passing the data itself to php in a safe way. Or you could even encode it as base64 (which is used precisely to avoid the embedded NULs problem); decoding from the php side is just a matter of calling base64_decode(); from the AS side, you don't have anything builtin, but there are classes for encoding base64 around (I wrote one some time ago). Of course, using base64 would add more overhead and will add to the size of the data you're posting (1/3 of the unencoded size), but maybe it turns out to be simpler than grabbing the binary data from php.
