ActionScript 1/2 :: Recursive Function Crawling Through Movieclips?
May 19, 2010
I have this function to find occurences of misstyped varaible names (with wrong lower / upper case). I have a movieclip called "debug" where I define and call this funciton ("getCase(_level0)"). But It never finds my testttt variable - If I put the test varaible in _level0 the variable is found.
var targetsCase_ary:Object = new Object();
var targetsLower_ary:Object = new Object(); testttt = 1 testttT = 1 function getCase(clip:MovieClip, recu:Number){ if (recu==undefined) recu = 1; var n:String; for (n in clip){ var sPath:String = clip._target + "." + n; var sPathLower:String = sPath.toLowerCase (); //trace(sPathLower + " " +

I think I have the recursion working properly, but I'm not able to get the originally requested item's property set to the right value.The goal here is to find the topmost parent (or "ancestor," depth = 0) of the nested item (a taxonomy based on Dictionary "parent" attributes), and assign that originally requested nested item's "ancestor" property accordingly.For instance, in
Apples
- Red
- - Empire
- - - Fresh
"Fresh"'s ancestor should be set to "Apples." While I'm attempting this on an "on-demand" and individual basis, I'm open to a solution that tags all children that are related to the same ancestor in one fell swoop or for statement, since that would probably be more efficient.
REQUEST
for (var mc:Object in taxonomy) {
var term = taxonomy[mc];[code]....
As you can see, while the recursion does find the root, the originally requested item still gets the default value.

So, I create standard AS3 flex project. In constructor goes only start();
rest of functions are basically this:
private start():void { f1();}
private function f1():void { f2();}
private function f2():void { f1();}
And it's standard recursion. SWF either breaks or loops as many times as I tell it. One f calls the other, which calls first... I do not want that.
I want f1 to do some stuff, calls f1 and closes itself. Than f2 works, calls f1 and closes. And so on.
Like having 2 sets of code that loops through.
What's the cleanest way to do that?

I want to vreate a recursive function that will search through my xml tree and display all the leaves(node values); this is the function that I wrote:
function searchXML (theItem) {
trace("theItem.*.length() "+theItem.length());
trace("theItem.* "+theItem);
trace("--------------------------------------");
if (theItem.*.length() > 0) {
searchXML(theItem.*);

I have a difficult problem with a recursive function. Essentially I need to 'slow down' a for loop within a function that repeatedly calls itself (the function); Is this possible, or do I need to somehow extract the recursive nature of the function?
function callRecursiveFuncAgain(ob:Object):void{
//do recursive stuff;
for (var i:int = 0; i < 4; i++) {
_nextObj=foo
callRecursiveFuncAgain(_nextObj);
}}

I made an app (Towers of Hanoi) and i added a "demo" button that solves the problem based on a recursive function. The button is supposed to make a move one step at the time, i mean one step at every few seconds so you can actually see how the algorithm works. The problem is i haven't really used the timer event before and i have no idea how to implement it in this particular scenario.
Code:
function hanoiPlay(n:int,a:Stack,c:Stack,b:Stack):void

Because it's a little hard to explain what I need.. I'll make an example.So.. I have the figure below. I mean.. that's what I'm trying to achieve. For that figure I have data stored in the folowing way._root.marc is an Array.All the paths that leave a square ... like From M0 if you choose 1 you'll get M1,From M0 through 5 you'll get to M3.. and so on.this is stored like_root.marc[0].p - the paths. If _root.marc[x].p.length is 0.. that means that Mx is the last one.. and has no paths assigned, like shown in the figure. My very big problem is that I need to position that MC's.. M3,M4.. all of them, according to the paths above them.
So, to position M2, i need to take a look at M1, and if it has any paths, more than one path, I need to move it further down. But this is not the end of it. If M1 has more paths that lead to other MC-s.. i need to take in considerations their paths too . This drove me mad for the last couple of days, and my time is slowly running out for my diploma What I've tryed till now was to build a function let's say... getNextY(m) that should return a number. A "ponder"?..like...to use it in a line like M2._y = (currIndex + getNextY(1))*dy;// here it should return 5 for instanceM3._y = (currIndex + getNextY(2))*dy;// here getNextY should return 1

I'm in a big big mess, trying to figure out how to do this for the last couple of days. I finaly came to the conclusion that I need a recursive function for what I'm trying to do.

For that figure I have data stored in the folowing way. _root.marc is an Array.

I've an all flash website embedded into an HTML page with SWFObject. The embedded index.swf consists of a menu and a Sprite. At first a home.swf page is loaded into the Sprite. When a user clicks a link on the menu, a new swf is loaded and placed in the Sprite, replacing whatever was there. This works nicely.
However, my problem is that the only content that appears to be indexed by Google (or probably any other search engine) is what's inside the alternative content <div> on my html page. I understand that Google can now crawl swfs, but, does it crawl swfs loaded with a Loader?
I should probably mention that I use SWFAddress for browser functionality: back/foward buttons and <title> text etc. However, the URLs sent to the Loader instance are simply filenames like "page.swf". This is important as google ignores everything after hashes in URLs, eg www.mywebsite.com/#/home.swf is treated as www.mywebsite.com/ by google. SWFAddress uses hashes in addresses for browser-swf interaction.
Is there any way for me to keep the menu visible to the user at all times and load the content elsewhere, thus maintaining my menu transitions? As far as I know, content loaded in <iframe> tags isn't crawled either. I'd prefer not to have to switch to static pages to get my pages indexed.

I am in a real distress - trying to make a menu looking like the one shown here:[URL]..That is a sort of "tsunami" if I get it right... On mousover, the elements nearest to the mouse grow - the nearer they are, the more they grow - like in the many examples of tsunami that you can find on the web.The problem I have is that as they grow, the elements should also push one another sideways, so that the menu sort of "walks" or "slides" sideways. Which is exactly what I cannot achieve.

I'm doing a basic site with frame labels on the main timeline whose name corresponds to the btn names. A simple otoAndPlay(evt.target.name); I have a basic navigation setup of 7 mcs with mouse eventlisteners for CLICK, ROLL_OVER and ROLL_OUT.
Example:
prepare.addEventListener(MouseEvent.CLICK, navigate);plans.addEventListener(MouseEvent.CLICK, navigate);retire.addEventListener(MouseEvent.CLICK,
[Code]....
Does anyone know a better way to do this so when my mcs are clicked they display the rollover content/art? In essence I'm trying to achieve that when the user clicks a btn it goes to that "page" and the corresponding btn stays highlighted. Pretty standard web navigation technique but I just don't know what the best way to do this in flash is and with how my site is setup.

I am making a SUDOKU generator(ActionScript2.0), which would (for now) generate the full and correct sudoku table. To do that I need to use recursive functions for calculating all the possible values. The problem is that when I try to run my program I get this error :
Code:
256 levels of recursion were exceeded in one action list.
This is probably an infinite loop.
Further execution of actions has been disabled in this movie.Is it possible to somehow work around this limitation?

I have a menu of 4 buttons and I'm trying to not be redundant and recursively use the same over, out, clicked function for each button by passing it's instance through the event handler.
I haven't had a whole lot of success finding the answer except locating a thread about creating custom classes....Which would be great, but I don't want to re-create my entire structure now. So I was wondering what the best approach might be.

While recursive scans are commonly use to scan through nested objects / data. It can go on an infinite loop, if some of the objects references one another. So what is the most effective way to scan all items, without crashing the computer, nor skipping a specified parameter?
Here is an example of a recursive scanner...
/**
* Triggers the scan function for each object given
**/
function recursiveScanner( object:* , scanFunction:Function ):void {
[Code].....
The objects will trigger scans for one another in an eternal loop.
I do believe in C/C++ : Each scanFunction call, will be added into a list consisting of scanned 'memory address', thus preventing a repeat. Is this even possible in AS3? Is there a more elegent way?

I have a Flex component that is a view of a data Object that recursively has a reference to itself.
For example if you had an Employee class that references a boss field of type Person, I'd like to nest the same view for that Boss. This shouldn't be an infinite recursive relationship (e.g. I'd only be viewing the boss field of each object).
I've tried creating an MXML component that references itself but when I run it locks up (seems like it gets into a recursive loop).
Is there anything you can do like includeInLayout conditions that will make sure it doesn't even instantiate that component.
