ActionScript 2.0 :: Checking If Symbol Exists In Library
Aug 13, 2007
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.

Library symbol "Card" is linked to class "Card" which extends "MovieClip". Library symbol "Card" contains a card background image.Library symbol "Ace" is linked to class "Ace", which extends class "Card". Library symbol "Ace" contains a TextField with a big letter "A".So we have Ace extends Card which extends MovieClip. Ace therefore extends MovieClip, but does not DIRECTLY extend MovieClip.When I drop an instance of Ace on the stage and compile the clip, all that shows up is the big letter A. However, I expected the background image from Card to be included, since Ace extends Card, and the Card symbol contains the background.It seems like Flash ignores symbol content unless it belongs to the top-level class being instantiated.I think it's LAME that one symbol can't extend another. The IDE could easily draw Card as a non-editable background while I'm editing Ace which extends it, and it should instantiate Card's content and then Ace's content when an Ace is instantiated.

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.

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.

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'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:

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:

In Actionscript 3, I'm trying to build a button to go back from a content frame to a main menu. When the button is clicked, IF the content frame has a movie in it, that movie should stop playing. Flash keeps throwing a "null object reference" error on all pages that don't include a movie. I even tried putting in a check to see if the movie exists, but that doesn't work, either.
ActionScript Code:
function return_to_menu( me:MouseEvent ):void {
if ( flashmo_contents.flv_movie ) { //this line produces errors in frames where the movie

I have 2 SWF, one of them (let's call it Resources.swf), that contains several symbols (most of them MovieClips) on its library, but, none of them are added into the stage ( the timeline contains only one empty frame),and then, the other swf (Main.swf), where I need to import some of the symbols from the other SWF.I have been looking around, and searching, but all the info that I saw, and tried, imports the symbols from the stage/timeline using things like:[code]If not,do I have modify my Resources.swf to work this out or do I have other alternatives?

I am trying to load a movieclip from the library onto my stage. But the name of the movieclip is read in from a user-entered text field. Typically, to load a movieclip from the library named, Bee, I would do the following:
var mc:MovieClip = new Bee; // this works.
But the name of my symbol is in a TextField. The following do not work:
// Attempt #1:
var mc:MovieClip = new userfield_txt.text; // No Good
// Attempt #2:
var str:String = userfield_txt.text;
[code]....
I realize the new operator requires a Class data-type, so how do I get the value stored in a String or TextField into a Class type?

I'm new to Flash, am working on my first Flash Project. I've been trying to move a particular symbol from my library onto the stage and when I do, I'm getting a "Resolve Library Conflict" error that says "One or more library items already exist in the document." and it gives me the choice to replace the existing items or not. It only appears to be happening with 1 or 2 particular symbols, not all of them. I did use this same symbol (as a graphic bullet) earlier in the project with no problem, but now it won't let me use it again. However, I have other symbols in the library that I have used multiple times throughout the project and I don't get this error pop-up when moving them into new frames. I don't see any mention of this in my Flash book, why I'm getting this and how to resolve it?

When you import a PNG into the library, Flash creates a symbol as well. It doesn't do this for JPGs, so I'm wondering if there's a setting that I can change that. I don't want it to create a new symbol. If it can't be changed, can anyone tell me why it does it for PNG and not JPG?

In the Flash authoring environment I can edit a library symbol and all on-stage instances based upon it reflect the changes. How can I do the same thing in ActionScript? There seems to be no way to address a library symbol.
For example:Inside Flash CS3, I have created a Square.swf file that has 100 instances of the library symbol Square.
Now, Square.swf is loaded into another file BlueSquare.swf and I want to change the Square symbol into a blue square so that all instances of Square become blue.How do I do this using Actionscript?
