Hello folks,

I have a list of swf files and I need to know the amount of frames of each one
of them. I tried the following:

1. I created a xml file called "data.xml" (an example with 5 files -
lesson1.swf, lesson2.swf, lesson3.swf, lesson4.swf and lesson5.swf):
<?xml version="1.0" encoding="iso-8859-1" ?>
<course>
<lesson id="1"><name>lesson1</name></lesson>
<lesson id="2"><name>lesson2</name></lesson>
<lesson id="3"><name>lesson3</name></lesson>
<lesson id="4"><name>lesson4</name></lesson>
<lesson id="5"><name>lesson5</name></lesson>
</course>

2. I wrote this script on Flash:

System.useCodepage = true;
var MyXML:XML = new XML();
MyXML.ignoreWhite = true;

MyXML.onLoad = function($sucess){
if($sucess){
for($i=0; $i<MyXML.firstChild.childNodes.length; $i++){
lessonloaded =
MyXML.firstChild.childNodes[$i].firstChild.firstChild.nodeValue;
loadMovieNum (lessonloaded + ".swf", 10); // loads
lesson[b][i]n[/i][/b].swf on _level10
_level10.stop();
[b]trace (_level10._totalframes);[/b]
unloadMovieNum (10);
}
} else {
trace($sucess);
trace("Error!");
}
}
MyXML.load("data.xml");

The [b]trace (_level10._totalframes)[/b] command results in [b]undefined[/b]
five times. So I tried the onEnterFrame function, believing that after some
loops Flash would recognize the amount of frames of the
lesson[b][i]n[/i][/b].swf file loaded on _level10:

for($i=0; $i<MyXML.firstChild.childNodes.length; $i++){
lessonloaded =
MyXML.firstChild.childNodes[$i].firstChild.firstChild.nodeValue;
loadMovieNum (lessonloaded + ".swf", 10);
_level10.stop();
[b]onEnterFrame = function(){
if (_level10._totalframes != undefined) {
trace (_level10._totalframes);
unloadMovieNum (10);
delete this.onEnterFrame;
}
}[/b]
}

But, onEnterFrame function is invoked just once, after the loading of
lesson[b]5[/b].swf. So I get the amount of frames of the last file only.

Now, I'm a little bit lost... I don't know what to do to improve this script,
and I'm wondering if there isn't a better way to get the _totalframes of a list
of swf files...

Any suggestions will be very appreciated!

Thanks in advance,

you have to wait until loading starts before you can access anything about the
loading swf, including its _totalframes.

so, your 2nd bit of code is a step in the right direction. but your
repeatedly defining (and over-writing the previous) onEnterFrame handler.

try:



loadA = [];
totalFramesA = [];
MyXML.onLoad = function($sucess){
if($sucess){
for ($i=0; $i<MyXML.firstChild.childNodes.length; $i++) {
lessonloaded =
MyXML.firstChild.childNodes[$i].firstChild.firstChild.nodeValue;
loadA.push(lessonloaded);
}
}
}
lo = new Object();
mcl = new MovieClipLoader();
lo.onLoadStart = function(target) {
totalFrameA[index] = target._totalframes;
index++;
if (index<loadA.length) {
mcl.loadClip(loadA[index]+".swf", 10);
} else {
framesF();
}
};
function framesF() {
// _totalframes stored in totalFrameA. do whatever
}
mcl.addListener(lo);
mcl.loadClip(loadA[0]+".swf", 10);
MyXML.load("data.xml");

First, thanks for the help kglad!

It didn't work here, "Error opening URL "..../undefined.swf". I'm not sure if
I understood how the function invoked by onLoadStart fullfills the loadA array
(specially how the "target" parameter is passed).

But I will study the events and methods of MovieClipLoader, it seems more
promising than loadMovieNum. In the meantime, I would like other suggestions!
Thanks!

Woo-hoo!! Now I got it! The problem was where loadClip was being called... I
moved it right bellow the for loop, and now it works!



MyXML = new XML();
MyXML.ignoreWhite = true;

loadA = new Array();

MyXML.onLoad = function($success){
if($success){
for ($i=0; $i<MyXML.firstChild.childNodes.length; $i++) {
loadA[$i] = MyXML.firstChild.childNodes[$i].firstChild.firstChild.nodeValue;
}
objMCL.loadClip(loadA[0] + ".swf", lesson_mc);
}
}
MyXML.load("data.xml");

this.createEmptyMovieClip("lesson_mc", 1);
objMCL = new MovieClipLoader();
objL = new Object();
index = 0;
objL.onLoadComplete = function(target:MovieClip):Void{
trace (loadA[index] + " - " + target._totalframes + " frames");
objMCL.unloadClip(lesson_mc);
index++;
if (index<loadA.length){
objMCL.loadClip(loadA[index] + ".swf", lesson_mc);
}
}
objMCL.addListener(objL);

great! and you're welcome.
