[Flashcoders] scoping issue (?) with static, recursive function
Okay, so I have an FLA with a series of embedded movieclips:
garden tree branch twig flower.
I want a static function -- in an as 2.0 class -- that, when given
flower, returns tree. In other words, you can give in an embedded
movieclip and it finds that clips ALMOST outermost parent.
Here's my class function:
class com.research.StaticRecurse
{
public static function
getOuterMostParent(mc:MovieClip,mcRoot:MovieClip):MovieClip
{
if (mc._parent._name == garden)
{
trace(inside getOuterMostParent: + mc);
return mc;
}
else
{
getOuterMostParent(mc._parent);
}
}
}
and inside the fla, I use the following code:
import com.research.StaticRecurse;
var innerMostChild:MovieClip = garden.tree.branch.twig.flower;
var mc:MovieClip = StaticRecurse.getOuterMostParent(innerMostChild);
trace(outside getOutMostParent: + mc);
the trace is as follows:
inside getOuterMostParent: _level0.garden.tree
outside getOutMostParent: undefined
As you can see, the first trace -- which works beautifully -- occurs
RIGHT BEFORE the return statement. But the value that's actually
returned is undefined. I've never encountered anything like this
before. To me, it seems as if I'm doing this:
function x():Number
{
var n:Number = 1000;
trace(n); //1000
return n;
}
trace(x()); //undefined
... which would be insane. I'm guessing it's a scoping issue that has
to do with recursion and the fact that this is a static function
(which it kind of has to be). Why is this happening? Is there a
workaround? Thanks!

You need a 'return' before the recursive call:

[Flashcoders] File works in Flash 9 player but not in 8
Here's a really weird one: I created a Flash 8 swf -- using
Actionscript 2.0 -- compiled it as a Flash 8 swf, but it doesn't work
in the Flash 8 player. It does, however, work in the Flash 9 player.
The file loads data in from multiple xml files. It actually works
fine, even in Flash 8, if I only try to load from nine xml files, but
as-soon-as I ad a tenth file, it stops working. By stops working, I
mean that when the swf runs, I only see the Stage background.
This same swf (without being changed in any way or recompiled) works
fine in the Flash 9 player.
The 8 player doesn't seem to be balking at the amount of xml, because
if I cut the code from the tenth xml file and paste it into the 9th
file, everything works fine. It just seems to choke on ten files.
//works in Flash player 8 and 9

In case it matters, the problems occur after 11 xml files, not 10.

Re: [Flashcoders] too many lines in one frame
Maybe, but the AS file was 115kb, and it had been working fine for months (during which time it was well over 32kb). I'm wondering if it's more about reaching some frame-AS limit than filesize.

[Flashcoders] flv sometimes playing sound only
I've posted a few times here about my video woes, and I thought I'd solved them all, but now there's a new one and it's really vexing: Sometimes the video is playing, but every once in a while, only the sound will play. It particularly seems to be a problem the first time the swf loads -- or if you clear your cache and then reload it. If you reload without clearing the cache, it works fine. It's as if the player needs to be primed by trying to play the video once and failing. After that, it works. Some details: --the video is being loaded via rtmp. --I'm using the flvPlayback component's activeVideoPlayerIndex and visibleVideoPlayerIndex properties to load videos into new players. --I've read that when using the rtmp protocol, you sometimes have to leave off the .flv extension from the path inside the .load() method. I am. It makes no difference. --I'm using the latest version of the component. You can see the swf here: http://bandtools.nabbr.com/bandtools/media/thepack/thepack04.html It's somewhat hard to reproduce the problem (sound but no video). It may or may not happen to you the first time you play it (and they be fine on a refresh). It may or may not happen to you if you clear the cache before playing. ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com

Re: [Flashcoders] setInterval creates tooltip, then kills it
Is there any reason why you need your tooltip text to be selectable?
Selectable text gives you the i-beam cursor when you roll over it, and the
i-beam interferes with button events. Try this...
myTextField.selectable = false;

[Flashcoders] twilight zone: flvPlayback doesn't work if there are too many functions in the fla!
Hi. Thanks for the help with my last flvPlayback issue (2nd movie wasn't
playing). Now I have a new one, and it's really freaky: the video was
playing fine and then all the sudden it stopped playing. It stopped when I
added a new function to my code. The weird thing is that the function had
NOTHING to do with the component. It was just a function that took in a
string, parsed it, and returned a parsed value. I wasn't even calling the
function. Just having the function in my code -- without calling it --
stopped the flvPlayback component from working. By the way, everything else
worked fine (it's a complex swf that reads in xml, does a bunch of as
drawing, etc.) No syntax error. Nothing. Everything works except for the
flvPlayback component. And when I comment out the function, the component
starts working again.
It gets weirder!
A co-worker of mine, who doesn't know anything about Flash, suggested that
maybe I'd exceeded the number of functions I'm allowed to have in one file.
I scoffed at that. The file isn't that long (1200 lines of code -- long, but
I've seen longer). But to placate him, I deleted the function and created
another one -- a dummy function -- that looks like this function
xyz():Void{} and to my shock, it also stopped the player. If I commented it
out, the player worked again. I have now done a bunch of tests and have
concluded that if I keep the number of functions at exactly what it was
before I added my string-processing function, the component works; if I add
any more, it doesn't. It doesn't matter what the new functions are named or
what they do -- the component doesn't like them. And it's ONLY a problem for
the component. Everything else is fine with however many functions I put in
the code. So it seems that the component DOES place a limit on the number of
functions you can have in your code.
WHY?
WHAT CAN I DO?
I'm thinking of ditching the component altogether and hand-coding a video
player. But I don't want to go to all that trouble if it's not going to
help!

[Flashcoders] 2nd rtmp video doesn't play
Join Date: Dec 2006

*2nd Video Doesn't Play!*
--
Hi. I'm trying to play two videos in the flvplayback component. The first
one is playing; the second isn't. Both paths are rtmp paths. I've read on
various message boards that you should remove the .flv extension from the
second path, but that doesn't help.
In my move, the component is called flvPlayer. There's a button called btn.
What's wrong with this code?
//these first two lines work fine.
flvPlayer.load(rtmp://path/to/media1.flv);
flvPlayer.play();
btn.onRelease = function():Void
{
//this doesn't work
flvPlayer.load(rtmp://path/to/media2.flv); //I've also tried without the
.flv
flvPlayer.play();
}
When I click the button, the first flv does stop playing, the skin on the
flvplayback component shows those little barber-pole stripes as if it's
loading a second flv, and then the loading animation stops. And that's it.
No video plays.
Just to be clear, everything works fine if both videos come from http urls,
but if they come from rtmp urls, only the first video plays.
