ActionScript 3.0 :: Checking To See If A File Exists Before Loading?
Jun 11, 2009
in AS3 to check if a file exists before loading it. There was not very much about so I wrote these classes to do it. There are two classes, the FileLoaderUtils and the UtilEvent. the FileLoaderUtils has the function doesFileExist(url:String) and when called the class uses the URLStream class to attempt to load the file. If the file exists a UtilEvent.FILE_EXISTS event is dispatched. If the URL is incorrect or the file doesn not exist a UtilEvent.FILE_NOT_FOUND event is dispatched.

I have a gallery loading jpegs from an xml file into a mc called mainPicArea, on frame 5. I have other content on frames 1,2,3,4,6,7.
I want to run an if statement to check whether mainPicAreaexists and if it does, then run a removeChild(mainPicArea), and if not do nothing.
[AS]
if (MovieClip.mainPicArea){
trace("exists");
//removeChild(mainPicArea);
[code]....
When I test, it comes back with the trace "doesent exist", even though it does exist.

My page has 2 tab menus. When the page first loads, it defaults to the first tab, but when the second tab is hit, an image is loaded to the stage. I want to remove the image from the stage once the first tab is hit again.I keep getting the error "Access of undefined property Image1" but the whole point is to check if this child exists with the if statement.
//Tab 1
if (Image1 != undefined) {
stage.removeChild(Image1);

In my script I create a button that when clicked, creates a blue square. However, I want to remove any blue squares that exist before creating the new square (because as it is a low opacity square creating another one will make it more solid, as well it's just more objects that the system has to keep track of).Here is my code:.as

I´m trying to check if one xml element has a child-element or not, i´ve tried things like if(myxml.doubtelement != null) ; if(myxml.doubtelement != undefined) ; and if(myxml.doubtelement != 'undefined') wich where the solutions i found in forums... but they don´t work at all. i´ve been looking at the xml methods and i found contains() method, but I found out that it works with the element content and not with the node itself.

The code that is giving the error is in engine.as

gtip is an instance name of a movie clip that is in the character when it gets loaded.Here is the code from the files;

My situation is thus: I have an XML file with entries, each of which contains a handle (linkage ID) to the movie clip that represents that entry onstage. So I dynamically load these symbols in from the library accordingly. Only problem is, I need to be able to count how many of those entries are valid, that is, how many of the XML entries have handles that actually do correctly correspond to the names of the symbols in the library. So right now in order to count the entries I am using the value of how many entries were in the XML file but this is wrong, I need a value of how many entries in the XML correspond correctly to a library symbol.
As it stands now, if all the names in the XML file match those in the .fla, all is good. Otherwise, issues. The thing is, I want this setup to be robust so the program takes responsibility and resolves issues if there are errors in the XML. Now, the only way I can see to fixing this simply, is if there is a way to check if a symbol exists in the library -- without actually trying to load it. That way I can count just those symbols from the XML file that also do exist in the library.

You all know the "loadMovie" command but is there a way to tell if the movie you want to load really exists? For example: I have a movie on my server names "asdf.swf" and I want to use loadMovie to open it. Well what If I want it to check if it exists before I try to load it? Also, can you load picture files to a movie? (gif/png)

I'm attempting to make a platform game. Each level is contained within it's own MovieClip, which has it's own class. Each of these classes extend the Level class, which provides basic functionality for all levels.
Each individual level has a numPlatforms variable which stores the number of platforms in that particular level. I currently have a for loop that runs from 1-numPlatforms and sets the level area (the image, more or less) the platform contains:

Is there any way to check if a variable exists within a MoveClip? I've trying comparing it to null and also to undefined, but neither works.

I have a form that is being created at the point the user clicks on. The algorithm is checking to see if a form exists in the same spot- if it doesnt, new object is created, if it does- result is traced. If no objects are on the stage- a new object is added. For some reason in this code- I get no results for the Mouse_Down event on the form itself. Method being called in main timeline:

I am trying to detect whether a movie has been loaded properly via the "loadMovie" method. Another option is somehow getting a boolean value telling me whether or not a file exists in a specific folder... or whether a url exists. Basically, I want to be able to know whether or not a client has added a photo to the gallery folder on the server.

I have to load a text file. First I want to detect if the file exists or not, so I use "if (rawTxt == undefined)".
Now, if the file exists and contains data, the condition n2 is met...it's OK! But now, if the file exists BUT is empty it doesn't meet the condition n2.. It's not "undefined" neither "not undefined" since any trace action accours.
In other words, how can I check that a text file exists...AND that it's empty or not (so that I can add a branch if that condition is met?) Try by yourself with an empty text file named "Favorites.ini".
Code:
var loadFavorite = new LoadVars();
loadFavorite.onData = function(rawTxt:String) {
if (rawTxt == undefined) {

Is there a way to check whether a loader object is in the process of loading something? I need to create an if statement that checks if the loader has an open connection. So far, what I thought of is:
ActionScript Code:
if(loaderInstanceName.contentLoaderInfo.bytesLoaded > 0)
{
// do something
}
Here, I'm just assuming that if bytesLoaded is greater than 0, than it's probably loading something. But I don't think it will revert back to 0 after the loader finishes loading an external resource. So after that, bytesLoaded will always be greater than 0 even though it isn't in the process of loading anything. Is there any other property that I can use which says whether the loader object has an open connection?

When running jfsl in flash command run it says it cannot find file:///C:/flash/FlashApplication1/FlashApplication1/FlashApplication1.as on line 7 (var doc = fl.openDocument(uri);) whereas it does exist at that location.I have looked at official doc on openDocument

var doc = fl.openDocument("file:///c|/Document.fla");
I tried to use file:///c| instead of file:///c: but it didn't work either.

I'm trying to get smoother steps in checking the ProgressEvent when loading the image to the Loader.At this moment my eventrogressEvent checks the progress aprox twice within a second. Is there any way to make it check constantly (or more often), so the progres bar "grows" smoothly instead of "jumping"?
