ActionScript 3.0 :: External Assets - Multiple Loader Sprite Instance
Jul 27, 2010
I'm loading some external assets with the Loader class. I've done this a lot over the years, but seem to be coming across a problem I haven't had before. I want to display two instances on the stage at the same time of a .png I'm loading externally. If I use the Loader instance's contentLoaderInfo.content object in more than one sprite, the bitmap just "moves" from the first instantiated sprite to the second. I've tried duplicating the sprite with Senocular's duplicateDisplayObject class, but for some reason, it's not working right. But shouldn't I be able to use multiple instances of an imported bitmap like this just as if it were in the library of the .fla? If so, what do I need to do?

Yes I know this topic has been discussed before, and I know that Senocular has a class that does it. But the question is...
1) Why did Adobe remove duplicateMovieClip();?
2) Did they intend to have any similar function? Or did they totally forget about external assets?
3) Is there a "Adobe reccomended" code that will do the same thing? (Not that I've got anything against Senocular :bow : but it'll be nice to know if there's a "certified" way of doing it.

This is a follow-up to another thread that is getting wordy and unfocused:

I am trying to load an external library .swf to use its embedded fonts, much like this method:
[URL]
However, the swf that is loading the font swf is loaded within a wrapper swf, and is defined as a separate ApplicationDomain as the wrapper.
Wrapper swf (app domain 1) <--- Player swf (app domain 2) <--- font library swf
The font is loading fine, and I'm even able to retrieve the font name (so I'm able to reference the object), but it is *not* showing up in the textfield as it should be.
When I remove the ApplicationDomain issue between wrapper and player swf by testing the player swf locally in the IDE (*not* loaded through the wrapper), it works fine. But I'm not sure how or why this is, because like I said, I'm able to get the font name so I'm able to reference it, it seems.
The TextField is being set to embedFonts, the font is loading, everything else seems to be working 100%, but there's some issue between the application domains that I just *can't* figure out.

In AS3 i am using the Loader class to load in multiple external SWFs (AVM1), each of which has a short animation which automatically plays when the swf is I obviously cannot control the timeline of these (i can't use local connection etc) but would like to load in the *.swf files, so they're in memory then add them to the stage when requested. the problem is that if i load them enmass. then use addChild when they are called, they have already played through and animated pre the addChild command.
(I cannot edit the swfs at all, and would rather not load them on demand at runtime)

I'm building a simple flash webpage using as3 in order to get accustomed to it. I've got some code for a preloader which, the end result works fine,but I cannot get the preloader assets to update with the loader data.To put it simply, I cannot get the code to update my text field that would display the percent done text.It only shows at 100 when it should go 1, 2, 3, 4...etc.Also I cannot get the bar_mc (just a simple bar graphic) to scale along with the percent loaded.
Code:
function handleLoadProgress(e:ProgressEvent):void {
while (percentDone < 100) {
totalBytes = loaderInfo.bytesTotal;[code]....

What's the best way to preload a bunch of assets (namely images) using only one progress bar?
Will the ProgressEvent automatically tally up the bytesLoaded and bytesTotal numbers for everything being loaded through that event?

I had a class that I was passing a simple argument to like so:
var quiz_1_2:CaseStudyQuiz = new CaseStudyQuiz(2);
addChild(quiz_1_2);
I now would like to use this class for multiple MCs in my library. I thought I could let Flash create a class for each of them and specifying the CaseStudyQuiz class as the Base class. When I do that, I get the following error:
1136: Incorrect number of arguments. Expected 0.

I have the following code which simply loads an external swf, puts it in the right place and should all be hunky dory.This works:
Code:
var myLoader:Loader = new Loader();
addChild(myLoader);
var url:URLRequest=new URLRequest("foobar.swf");[code].....
to set the dimensions of the loader so the external swf doesn't 'spill over', the result is a blank screen. No matter how high I set those dimensions it just doesn't display anything.

I've seen that it's very simple to create a document class (a class associated to the main timeline itself), or an instance of a class which is linked to a single asset (e.g. a movie clip).But what if I need to implement a class (let's call it Main) which uses multiple assets from the Flash library? The only way I know to do this is by instantiating any asset with its linked class, and passing them all to the Main constructor like this:
ActionScript Code:
var asset1:Asset1 = new Asset1(...);
var asset2:Asset2 = new Asset2(...);
var asset3:Asset3 = new Asset3(...);
[code].....
This is kind of a tedious process, especially when the composition hierarchy is long and you have to pass them all as arguments through many nested classes.For instance, I needed to link a preload sprite (the typical circle in gradient color which is constantly rotating until the load is complete) from the library to any thumbnail class of a gallery, which in turn is part of another class, which in turn is part of the main class. So I needed to pass this preload clip as an argument throughout the nested classes.

Loading a Sprite or MovieClip from the library to the Stage is simple. You just export the symbol and do the following code:
var mySp:Sprite1 = new Sprite1();
addChild(mySp)
assuming the exported sprite is called "Sprite1" and the base class is flash.display.Sprite
But what if you have many sprites and want to encapsulate this into a function with the sprite name passed as a string? What would the code in the function look like? Somehow you have to cast the string as the name of the sprite class defined in your export but I'm not sure how. I've seen a sample using the "as" keyword but try searching "as" in the help you you don't get much help.
Code:
function loadSpriteFromLibrary(sSpriteName:String)
{
//load the sprite with an exported name passed into sSpriteName onto the stage
//what would the code look like?
}

Do you know why this AS3 code works:
var loader = new Loader();
loader.load(new URLRequest("http://127.0.0.1/items/boing.png")));
var o:DisplayObject = addChild(loader);
o.x = 100;
o.y = 100;
But if I cast to sprite it doesn't work? Ie the sprite appears on (0, 0) instead of (100, 100):
var loader = new Loader();
loader.load(new URLRequest("http://127.0.0.1/items/boing.png"))
var o:Sprite = Sprite(addChild(loader));
o.x = 100;
o.y = 100;
How would I properly have a sprite instead of a DisplayObject? I need some sprite's features (drag'n drop, useHandCursor...), yet I wish I could still use the very quick writing with the loader.

I am trying to load assets from an external swf. As in:
I drew a square in flash Made it into a symbol made sure to check the "Extract for Action Script" to doubly check I created an instance of it from within the asset file. went to my loader file loaded the assets.swf tried to find the class variable using "getDefininition" FAILED.
from what I'v been seeing from around the web the following code should work. (I actually copied it word for word from one of the tutorials) but it doesn't work.
import flash.system.ApplicationDomain;
import flash.display.MovieClip;
var myLoader:Loader = new Loader();
[Code]....
there should definately be class definition for XIconG though because I tried it myself from within the Asset.swf file. also I'm not sure whether this helps you, but when I tried to debug, I looked at the event.target.applicationDomain variable from the debugger menu and under it it said domainMemory = null. I don't have a clue why that is though.

I use the Loader class to load external swf. And then I want to duplicate that object.What is the way to go? Is there really no easier way then senocular's duplicateDisplayObject function? Or how about just declaring a new Loader, and reloading the same path from the cache? Its a cheap way of doing it?

In AS3 / CS4 I'm trying to programmatically create a bunch of rectangular objects, let's call them 'cards', that will contain an image and a colored background and eventually some other elements like text. I want to create alot of these cards and move them around inside of a larger panel (also a Sprite) of sorts. I can successfully create colored rectangles in my cards and place the cards where I want in the panel, but whenever I try to add an image to a card, I can't seem to position the image inside the card's coordinate space, it ends up being placed inside the larger panel's coordinate space instead, even though I'm adding the image/loader as a child of the card. I thought maybe it had something to do with having to wait until the image loading was complete, so I added the listener as a test but that didn't work. Here's the code:

I want to load an external image (dest) and display it on the stage, and i want to load another image (src) which will not be visible. When i hold the left mouse button on the image that appears on the stage, then a function that start copies the src image to the dest will be invoked. Actually i want to reproduce the scratch effect on an image that hides another underneath. here is my code [ the copypixels function is triggered on mouse_move event for debug purposes ]
package
{
import flash.display.Sprite;
import flash.display.BitmapData;
[Code]....
Although the two images are loaded into memory and the first one is shown on the stage, when the mouse_move events triggers the corresponding handlers the copy does not work.

I thought since a Sprite is a display object container and I can add an instance of a MovieClip to it I should be able to reference the MC through the Sprite.
var bh1:Sprite = new Sprite(); beerChan = new BeerChan(); bh1.addChild(beerChan); trace("bh1 "+bh1); trace(bh1.beerChan);
1119: Access of possibly undefined property beerChan through a reference with static type flash.display:Sprite.

I want an air application to be able to update the assets it uses, but minimizing the download needed, so only downloading files added since it last updated.I'm thinking this would include a server portion which would zip the needed files based on a version number? Has anyone implemented anything similar / got any thoughts on the best approach to building this sort of system?

I'm trying to write a gallery application in Flash (AS3). It uses a simple XML document to specify a series of images like this:
Code:
<Gallery name="foo">
<Image src="foo/1.jpg" />
<Image src="foo/2.jpg" />
[Code]....
I have a class which parses the XML and displays the images (which sit locally, relative to the .swf file accordiing to the 'src' properties in the XML above) in a UILoader instance. This works great until I move the .swf file somewhere else, as the images aren't part of the compiled file, and obviously it's now looking for them in the wrong place.
I understand that you can use [Embed] to embed assets into your code (this is how I include the XML document), but I can't use it to embed the images. Is there a way I can embed the images in my flash document, and address them using the src values obtained from my XML?

I have a Flash file that will act as a slideshow, the images change when the sound that is to be played with each image is complete (using
soundX.onSoundComplete).
I have a folder for the sounds and one for the images. I have Flash load those assets via XML. I use XML to organize the order of playing the images /sounds.
[Code]...
My question:
Is there a way to not hard-code the image/sound names in XML and instead use it to organize and pull the assets from their respected folders? My goal is to be able to have Flash and XML working as an automated process and all I have to do is add images w/their respected sound files in their folders and never have to open Flash or XML. The Flash and XML would just automatically populate the slideshow per the number of image and sound files I add.

I have set up a functioning xml image gallery with simple left and right arrows. I am now trying to make it an infinite looping gallery swapping the first and last sprites in an array and + and - their x value so they "physically" move in the photos container.
All of this works fine except for the actual loaded image. The xml data, name description, and image to be loaded are set up in one function and all the data is added to the sPhotoSprite (sprite) in this function. This All works perfectly..
A second function is then called to add the current image:
var currentImage:Loader = Loader(evt.target.loader);
then currentSprite.addChild(currentImage); (the sprite is declared at the start)
The problem being that the sPhotosSprite is no longer reference-able. I've tried :
imageLoader.contentLoaderInfo.addEventListener(Eve nt.COMPLETE, function( evt:Event)
{ imageLoaded( evt, sPhotosSprite )
} );
But this only ever returns the final sprite. The same problem of only ever returning the final sprite occurs when I try setting an external sprite to hold the current sprite in it and then referencing it in the second function.

I have a swf called "myfile.swf" with a mp3 set to export for actionscript, and the Class has been called "soundName"With the following code, the sound plays great...
Actionscript Code:
var bgURL:URLRequest = new URLRequest("myfile.swf");var swfLoader:Loader = new Loader();swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadProdComplete);swfLoader.load(bgURL);function loadProdComplete(e:Event):void { var tmpSound:Class = e.target.applicationDomain.getDefinition("soundName") as Class; var snd:Sound = new tmpSound() as Sound; snd.play();}
This lets the sound play great. But, because of what I'm trying to do, i would like it better to put the swf into a movieclip, then play the sound from there.
But i cannot seem to get it to work. The following code adds the movieclip to the stage fine, but then i have no way of accessing the library assets (i.e the "soundName" mp3) from the swf inside of the movieclip.
Actionscript Code:
var bgURL:URLRequest = new URLRequest("myfile.swf");var swfLoader:Loader = new Loader();swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadProdComplete);swfLoader.load(bgURL);function
