ok, i figured it out.
it works if i make reference to where the function is.
this.function();
_parent.function();
if i just call the function:
function();
it is where I was getting stuck, but it all works now.

So far I've only been able to achieve that in Illustrator and then
saving
the perspectively squished vectors as a .swf What I'd love to do
is to
get
that perspective squish done within Flash 8 using script.
I know about 3D program extensions for Flash like Sandy, but I
find them
cryptic (at best) and over kill for my simple needs.
Using something like Sandy is the only choice you have. For example:
http://sandy.media-box.net/blog/distortimage-20-the-fastest-way-to-
freely-distort-image-with-flash-in-actionscript.html
http://sandy.media-box.net/blog/distordimage-the-way-to-distord-
bitmaps-by-code.html
You need something like this. This is done by dividing an image in
triangles
and then projecting them.
But you'd still have to be careful, as simple distortion ISN'T
perspective.
The above examples are simply distorting the image, but not
accounting for
proximity (it's just squishing the texture). If you get a side too
thin,
it'll just look thin, not "far".
This is an old example, but uses a similar approach but with correct
calculation (each side of the box is made of 4 triangles):
http://www.nkag.co.jp/
For something like that, you'd need to either build a complex plane
with
Sandy, using a bunch of squares (so it will do correct perspective,
or close
to it anyways), or build the whole calculation and projection
yourself.
Which can be done, but will probably take some time.
If you have a VERY simple drawing, you could directly draw it using
the
drawing API. You'd need to encode all your points and redraw based
on 3d
positions. This would be the best choice quality wise, but again
depends on
how your 'image' is, and could be quite slow.

This is advice is not exclusive to the realm of ActionScript but to OO
in general. Unless carefully orchestrated, making method calls from
within the constructor can result in unexpected results. It becomes
more
apparent when derived classes are instantiated and there is confusion
between expecting a derived class to be initialized but the base class
has not been fully initialized.
The other thing to note is that ActionScript does not have
deconstructors (with the exception of MovieClip.onUnload which I find
great). So when finishing an application, your objects must also know
how to 'finish' themselves and those objects that it created. If
you put
great care into making a constructor method in each of your
classes, you
should put some thought in a dispose() method which will be
responsible
for cleaning up what it started (for example, remove the movieclips it
created dynamically).

Subject: [Flashcoders] Faking 3D perspective of a 2D map in Flash
8..?
Hello.
I'm trying to take a vector map of North America and produce the
sense of
'flying over' it. I want to have the flat map tipped along the X
axis, so
that the bottom (Florida, Texas, etc.) appear closer and the top
(Nunuvut,
Greenland, etc.) appear farther away.
Then I want to be able to pan the map left and right, up and down,
and
'zoom' in by scaling it.. scaling it a little faster vertically so
that it
seems to flatten out a bit as you "get closer to the ground".
So far I've only been able to achieve that in Illustrator and then
saving
the perspectively squished vectors as a .swf What I'd love to do
is to
get
that perspective squish done within Flash 8 using script.

If these are functions that don't reference a particular instance
(i.e.,
don't use the "this" keyword), then it's better to make a static
utilities class (similar to, e.g., Flash's Math class):
class utils.controls.MyFunctions { // Think of a better name....
public static function functionA():Void {
// ...
}
public static function functionB():Void {
// ...
}
}
// In your class:
import utils.controls.MyFunctions;
class utils.controls.ClassA {
public function someFunction():Void {
// ...
MyFunctions.functionA();
MyFunctions.functionB();
}
}

Sorry, pasted the wrong URL. I meant this:
http://gotoandplay.it/_articles/2005/10/mode7.php
Or just do a search for "mode7" and "Flash". Not "true" 3D, but I
think it's what you're trying to do.

Hi all,
Sorry if this is noob question, but it has been several months since I
have had to do fancy text effects in Flash... I am on XP pro using
FP8... What is currently the best component or external app for
creating
flash-based text effects?
Swishmax still the standard?
<http://snipurl.com/iwzt>
I do not need a ka-zillion effects, just looking for a tool to help
streamline production (but prefer non-cheezy FX).
Any links/tips/suggestions you guys/gals can give me would be
fabulous. :)
Many thanks in advance.
Cheers,
Micky

Please forgive me if this is a repost. It did not appear for over
24 hours
after I posted it. I changed the subject line in case the spam
filters
blocked it due to killwords in the subject...
This may be a very stupid question, but I did search online and not
find the
answer. I saw examples of Flash apps (eg the quite fun Guess-the-
Google
http://grant.robinson.name/projects/guess-the-google/ game) that
grab images
from Google Image search, but I couldn't find any coding examples.
I don't
even know if the right way to do it is stupidly low-tech (by making
a query
string URL and parsing the page Google returns) or involves web
services
etc. (which I have never used).
I am supposed to call the potential client tonight to tell her
whether I can
do it and how much work is involved etc. She hired someone else a
few years
ago (a "professional programmer" on her campus IT staff) to do it
who was
unable to figure out how to grab Google images and incorporate them
into the
page. He used Javascript/DHTML as the front end. I intend to use
Flash as
there are many multimedia elements.
I have a potential client who wants their site to incorporate
Google Image
Search results. I have never used Google web services or their
APIs, so I
don't know how much work this will involve and what server side
resources
are required. I will be using Flash 8 and PHP (if necessary).
Also, do people use the Flash webservices component/class for
anything
real or does one always end up doing one's own server-side coding
(aside
from wrapping the web services call to get around security
restrictions)?
Is there a reason to use a web service rather than constructing a
query
string and parsing the results?
Forgive me if this is newbieish. I am a server side newbie, but
not an
Actionscript newbie.

This is totally driving me crazy.
I'm creating a textfield as a sub to another clip, setting it's width,
making it autosized, giving it a stylesheet. I then toss in it's
htmlText.
I just want to know if the darn thing is one or more lines. Trouble is
it's not reporting back properly...it seems as if it's just in the
middle of adjusting itself or something, as if I trace out a lot of
stuff, it works out fine. But I shut off tracing, and it stops
working.
For example:
var mTitle:TextField = mcTxt.createTextField("mc_title", 6, tR.x+20,
tR.y-14, 230, 0);
mTitle.autoSize = "right";
mTitle.wordWrap=true;
mTitle.selectable=false;
mTitle.html = true;
mTitle.border=true;
mTitle.multiline = true;
mTitle.styleSheet =_global.gPrefs.CSS;
mTitle.htmlText = title;
fontsize = 30; // i know this
lCnt = (mTitle.textHeight/fontSize);
Sometimes lCnt works and sometimes it doesn't -- and I'm tracing out
all elements.
I've even tried to do something like
while(mTitle.htmlText!=title){
trace("not there");
}
But that doesn't work either.
