Re: [Flashcoders] Query String + Loader odd issue

[Ktu]

I have an idea, not much of one, but worth checking?

Publish everything and test it live.
You never know, sometimes stuff like that happens.
(supposing you haven't already tried that)

Re: [Flashcoders] strange TypeError: Error #1034:

Hi, Preston,

What does the AboutLandingButton class extend in the class definition? And
what do you have set for the two values in Linkage in the library symbol?

If all else fails, blame Nat Harris.

[Flashcoders] strange TypeError: Error #1034:

[Preston Parris]

Hey all,

I have three buttons set up that are tweening in on the timeline, they each
are movieclips with the same associated class, two of the buttons work and
have no problems, the other one give me:

TypeError: Error #1034: Type Coercion failed: cannot convert
flash.display::moviec...@3b70b431 to
com.mellowmushroom.ui.about.AboutLandingButton.

I have made sure that the instance names and movieclip are the same through
out the animation, I even tried creating an entirely new clip and not
animating at all, I still get the same thing.

The other wierd thing is that the button still works even though it gives me
an error, like the properties that are set in the AboutLandingButton class
still apply and work for that button.

This is driving me crazy, any help in the right direction would be very
awesome. Thank you!

Re: [Flashcoders] Sound.extract

[Gregory Boland]

Ben,

Your going to want to perform an FFT (Fast Fourier Transform) and move from
the time domain to the frequency domain.

And to be more specific I believe you are gonna want to perform a Discrete
Fourier Transform.

I know a lot of work has been done on this in C and perhaps you could find
something and port it over to Actionscript.

There could be a problem computing all of that in real time though.

best of luck

[Flashcoders] gzipped xml receiving with flash

[Jiri]

Hello list,

Would it be possible to have a apache server return a gzipped version of 
xml (using the mod_deflate) and then uncompress the gzipped file in as3.


I guess that the BrowserMatch inside the httpd.conf would need to be set 
to a HTTP request comming from the flash player.


Would it possible for the flash player to mimick a call made directly 
from a browser? So that the apache returns an actuall gzipped version.


If it could be possible, how would this then be handled inside flash. I 
reckon the loader would need to load the file as a BINARY and then a 
gzip parser would deal with it?


I know AMF would work for what i want, or have the server preprocess the 
 files into a .zip. But i was just wondering and curious.


As my questions probably reveal, i am not an expert in this area, so 
excuse me if my questions are really naive.


Jiri
