Is there any way to determine if a (anonymous) function has defined the ...(rest) parameter in ActionScript 3? I know there's the function.length property, but it only counts the explicitly defined arguments.
View 2 Replieshow to do this
function foo(x:*, ...args):* {
}
function bar(x:*, ...args):* {[code].....
how to expand args ? when I call bar(1,2,3), I wish it call foo(1,2,3), but it call foo(1,[2,3])
Is it possible to wrap a variable-length-arguments function in Actionscript?[code]but it didn't work since sprintf was called with just 1 extra argument, i.e. the Array args.
View 2 RepliesLet's say I have array foo and a positive integer y, where foo.length > y.I want to remove elements from foo so that foo.length becomes y (or very close to it).Also, I need to preserve the first and last element of foo. The indices of the removed elements must be spaced apart as equally as possible. Foo can be sliced, or it can be used to create a new array.
Example: if foo = [a,b,c,d,e,f,g,1,2,3,4,5] and y = 6, then trimmedfoo could be [a,c,e,g,2,4,5] or maybe [a,c,e,2,4,5], but not [a,c,e,g,2,4] because the last element of foo is missing.
I am trying to get the length of arrays within an array, here is my example (MX 2004):
[Code]...
I get an output of of 3. the number of variables within the first array, this is not what I had expedted.
do anyone know how to script the dynamic text length to the amount of text in the text file instead of manually drag it to the length?
Code:
myLoadVars_lv = new LoadVars();
myLoadVars_lv.onLoad = function(success) {

I have a function that uses the ... rest argument as follows:
public function dispatchActions(... actions):void
{
var params:Object = new Object();
params.actions = actions; // I also tried casting ie. = (actions as Array)
this.target.dispatchEvent(new ActionEvent(ActionEvent.dispatchActions, params));
}
I call it using myActionObject.dispatchActions("all"); The problem is that when a listener receives the dispatched params object and try to access the actions array, it does nothing. If I try to trace evt.params.actions it traces blank and if I try to trace evt.params.actions[0] it traces undefined.
ex:
function actionsListener(evt:ActionEvent):void
{
var actions:Array = (evt.params.actions) as Array; // I also tried without casting
trace("actions", actions, "actions 0", actions[0], "action 1", actions[1]);
}
This is the output: actions actions 0 undefined actions 1 undefinedI don't understand why I can't pass the ... rest argument through an object as an event parameter. How can I make this work?
I am trying to use the class Sound of actionscript.My code is really basic :
var snd:Sound = new Sound();
snd.load(new URLRequest("mysound.mp3"));
trace( new String(snd.length));
snd.play();
The audio is playing very well but in my trace, I get 0 instead of the length in milliseconds of the Sound.
I have ben trying to figure out how to make slideshow that will recognize how many pictures are specified in the XML document length and repeat when it reaches the end of the list. I have not been able to wrap my head around it and although I have seen somewhat similar posts here, My hope is to make a slideshow that others can update by editing the XML document only.

I have text from an XML file that dynamically loads into a scrollpane.
The text appears in the scroll pane, and scrolls just fine --- but it doesn't show the full length of the dynamic XML text.
How can I make the length of a dynamic text area VARIABLE --- so that it expands to fill the length of the XML document?

Googling and trying, I've found: Variables identifiers cant begin with numbers and can only contain letters, numbers and the _ character. I was wondering if there is a length restriction.

View 1 RepliesI'm trying to do a test on the length of a string and then call a function depending on the result. This is the pertinent excerpt from the fla file:
Code:
_loc4._comment = candles[_loc3].comment;
// I want to find out the length of _comment and call differently depending
_loc4.onRollOver = function () {
if (_loc4._comment.length > 0 && _loc4._comment.length < 60) {
show_comment(this._comment, this._x + this._parent._x, this._parent._parent._y - 50);
} else {
show_comment(this._comment, this._x + this._parent._x, this._parent._parent._y - 100);
}};
Basically I want to check the length (in characters) of _loc4.comment and if its under 60 call with an offset of 50 and if its not call with an offset of 100.
I've done my own delay function as following:
Code:protected function delay(func:Function, milliseconds:int, ...statements):void

I have an 11 minute video (.MOV) that I want to convert to an FLV. The file is about 29GB. I first tried to convert it using the CS3 Video Encoder but only the first 5:00 were converted. I tried this a few times with different settings but got the same results. Then I switched to Cleaner but again, only about 5:00 was converted. The length is not exactly the same but close enough for me to think that there might be a 5:00 limit to how long an FLV can be. Or is there a limit to the size of MOV the encoding process will handle?
View 1 RepliesI have 10 dynamic text fields inside a movieclip, which are populated via an XML file.However, the xml file sometimes has less than 10 items. It never has more than 10.

I can visualize it, but I don't know how to write it.Basically what I need the code below transformed in to is this... (notice the #'s)

Each line in the dynamic textbox has 15 characters, and yet you can notice the difference in the length(between each line).
I want to make the length of each line look same if they have same number of charaters.
I am trying to find out what the max length is for a string because since as3 doesnt provide any methods for removing characters from a string by changing the initial string itself, i am going to have to stick to re-initializing.I did a little test to see how long it would take for my program to break using the following code:
Actionscript Code:
+[code]..............
The program crashed at a string length of about 500 million.
EDIT:however before it crashed,it performed the incrementations with reasonable performance.
EDIT EDIT: which is strange since my ram still had over 2 gig the program didnt use

View 1 RepliesI am using as2 to stream some mp3s. At the moment I have an attribute within the xml for giving me the length.I guess the length for the mp3s is buried in the mmp3 file somewhere. If I load the files in totally first, then I can get at the info (ID3 is it?) however, this doesn't work for streaming them . Or rather, I can't make it work! (I have found posts which suggest making an estimate if you know how much has downloaded in so many seconds and you know the length etc etc - but this is exactly that - an estimate!)So my question is how do I get the length of an mp3 clip that I am going to stream?

View 5 RepliesI need to get the length of an MP3 file.I tried using the following code: myFile.id3.TLEN; yet it didn't work.I copied (and changed a bit) the code from the help files and got this thingy:
myFile.onID3 = function(){
for( var prop in myFile.id3 ){
trace( prop + " : "+ myFile.id3[prop] );
}
}
myFile.loadSound(run_url, false);
The code shows me all the parameters I can get. Seems like my MP3 file used id3v1 which may not support time length, so using Winamp 5.3 (last update), I passed the information to id3v2.so I got some more parameters. Here's the output:
COMM :
TIT2 : MySong
TPE1 : Almonimus
TYER : 2006
[code]....
Seems like I still don't have the required parameters in the id3tag. I am aware that Winamp doesn't support id3v2.4 very well, so I downloaded a demo of Tag&Rename 3.2, and as you can guess, even after opening the file and resaving it, I can't get this parameter.
I have an xml file (attached). And what I need to do is find out the number of clients in the list

This is what I have so far but it always returns 0.
