ActionScript 3.0 :: Creating A Loader From A ByteArray?
Jul 15, 2011
I'm having some problems creating a Loader from a ByteArray. The first time I open my application I save in a cache the bytes loaded in the loader.contentLoaderInfo. The second time I open the application I'm loading from the cache the bytes saved previously and creating the loader like this: loader.loadBytes(bytes); But, It seems it has a problem recreating the loader. All the bytes are loaded but when I want to access the content I don't have it.
i like to ask about one thing If i create Loader and load external image by URLRequest , ill have result :
loader.content is Bitmap loader.content.bitmapData is BitmapData But if I use Loader.loadBytes(ImageBytes) , result is different even if ImageBytes is loader.contentLoaderInfo.bytes :
bytesLoader.content is MovieClip bytesLoader.content.getChildAt(0) is BitmapData bytesLoader.content.getChildAt(0).bitmapData is BitmapData
I am trying to create a new swf with AIR and Flash CS3. All I want to do is push a button and have a new swf saved to the desktop with a line of actionscript in it. The actionscript can be anything stop(); - for instance.I have been messing around with ByteArray and I can save an image to a swf but I can't find any information on what I want to do.
I am working on a game, made with Flash (using AS3) The game has a fast ball and when this ball hits an object it has to make a sound... but the sound starts with delay (so the ball is far away when the sound is played).This sound is edited by me and it hasn't got any silences at the beginning.The method i'm currently using is the simplest one:
public var sonidoPuntos1:sonidopunto1 = new sonidopunto1()
and then...
sonidoPuntos1.play()
I am trying to introduce the file into a ByteArray and then playing it from there...
I'm a designer who uses ID to create eBrochures. I can of course export SWF files and associated resources from ID to upload for web usage, but what I'm trying to do is create Full Screen projectors (amac and PC of these files). I have Flash Cs5, but know nothing about it. I can of course use the Flash PLayer Debugger to openthe ID created SWF and use the 'Create Projector Command' to make a self contained Projector, which is *almost* what I need.
Only problem is the SWF is not / cannot be set from ID to open in Full Screen mode, so the projector inherits that characteristic. Is there some easy way to add some script to the ID file so it open full screen? Or is there some kind of shell FLA I can get that would simply say something like "open content.swf and play full screen" then I can use that standardised name for my SWFs and make a projector of that ?
Ive been using the loader a lot of upload images into my movieclip. But the only way I know how to do it is load the content, add an event listener, wait for it to finish finish the job in the handler using the reference to the loader like this.[code]...
I've been trying to create a simple loader class that loads an image file onto the stage.
Writing the code to perform the task is simple via the main timeline:
Code: var picloader:Loader picloader = new Loader() picloader.load(new URLRequest("photo/1.jpg"))
[Code]....
How should I write the class such that it performs this function? Ideally I would like to specify the file I want to load eg. loadimage("photo/1.jpg") when I run the method.
I am creating a photo gallery using the loader component, however some of the jpgs are around 240k so I want to add a custom preloader. The issue I am having trouble with is... how do I set up a preloader that I have made to activate when the loader component loads a new jpg via the myLoader.contentPath = "sample.jpg"???
I am using a sliding thumbnail gallery w/ a static main image behind.
Anyone have a tip for settingup a preloader for the loader? Never had much luck making preloader.
I have two swf files, each one almost with the same classes, the most important one is a Singleton class, each swf does "singleton.getInstance()". The diference is that one swf is like a container and the other one is like a module. So when the container loads the module from an absolute path like loader.load("file://c:/modules/module.swf") or loader.load("[URL]"), two different singletons (same class) are created
But when the container loads from a relative path like loader.load("module.swf") , just one singleton is created (that is what I want) I am just intrigued with this behavior, could someone explain me this? PD: I believe is something related to loaderContext and applicationDomain but It also appears that isn't working right. -Patricio Foieri , Vertigo Labs
The title describes the problem: Loader.load() is firing the INIT event, but in my listener it's reporting loader.content as null. The description for INIT event is "Dispatched by the associated LoaderInfo object when the properties and methods of the loaded SWF file are accessible."I'm loading a lot of JPG images, and 95 percent of the time it works fine; the init listener fires and reports valid loader. content.I absolutely need loader.content available because I need to set the bitmap smoothing property to true.I've tried using Event.COMPLETE and it has the exact same problematic behavior.
I'm feeling a bit low now as I have been suffering this for months. A simple loader loads my simple game and runs VERY FAST on even slow pcs BUT when I build this other loader, it goes quite slowly and I don't know where the app is going wrong. WHERE is the processing consumptoin coming from out of my app.
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 got this very strange behavior from FlashPlayer debugger 10.1 r82. When I call loader.load method, no ADDED event is dispatched to the loader object. But if I open the file and call loader.loadBytes instead, an ADDED event is dispatched to the loader object. I suspect the ADDED event is dispatched because the content is being set as the child of Loader object, but why in the other case it is not dispatched?
the file loads correctly but the loading screen only flashes up at the end.The only thing being exported in frame 1 is the loader image, and that is extremely small.Is it possible that there's a queue of things being loaded and the loader image is at the bottom of that queue? Since that was one of the last things added to the project
i have a main loader swf file called loader.swf and it loads an RSL.swf (runtime shared library for my swf files) and then 10 swf files, each one to a container (fE.: movieclip '01' in loader.swf, then movieclip '02' and so on). the 10 swf files have a lot of references to RSL.swf, and i have to use RSL.the problem is when loader.swf loads the RSL and the other 10 swfs the loader throws errors like this:
Code: *** Security Sandbox Violation ***[code]...
then i put in EVERY swf files (loader,RSL and the other 10) the code Security.allowDomain ("*") but throws the same errors...
I'm loading some images with Loaders, cloning the BitmapData to a new Bitmap, and adding the Bitmap as a child of a Sprite. So far, so good. I want the Loaders I'm using to be removed by garbage collection, which they seem to be. The problem, or so it seems, is that when the Loaders are cleaned up, the Bitmaps I'm creating lose their data.
Edit: All this is happening when a class is instanced, and many copies of this class are being used as actors in a game. As the Actors are being created the older ones are losing their BitmapData to garbage cleanup. When all of them are finally loaded, only the last few are visible. I've rewritten my posted code as a class. If I prevent the Loaders from being cleaned up by somehow keeping a reference to them, the Bitmaps don't lose the data, but I don't want these Loaders hanging around.
I am attempting to load multiple images in AS3 and I'm exploring different options on how this can be done.I would like to have to only use one Load() instance and handle the various image assignments in the onComplete handler...here is my first attempt:
var buttonLdr:Loader = new Loader(); buttonLdr.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onLoadError); buttonLdr.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadCo
Sorry for the complicated topic. I got a .swf that loads in other .swfs. Rather than figuring out how to make a loader for loading .swfs I thought I'd just use a simple loader in the .swf I'm loading.
However, it doesn't work. It starts fully loaded but doesn't finish. Heres the AS:[AS]_root.stop(); PercentLoaded = _root.getBytesLoaded()/_root.getBytesTotal()*100;
how to create an image gallery that loads external bitmaps. It also has some nice fade in/fade out effects using Tweener. I was wondering, what would I need to modify from my code to load MovieClips from the library instead of the external JPEGs.
Code: import caurina.transitions.Tweener; var btn:Object; var disabledBtn:Object;
I have a main "shell" swf which, by clicking several buttons, will load/unload various external swfs into a Placeholder_mc which resides on the main timeline in Shell.swf In the documentation and tutorials I've seen a couple different methods, and I'm not sure I quite understand the difference, or at least the reason you would use one over the other...In the 1st method, you can just add the Loader object using the addChild() method:
Code:
var myLoader:Loader = new Loader(); var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf"); myLoader.load(myURLRequest); Placeholder_mc.addChild(myLoader);
This will apparently add myLoader to the display list once it has completely loaded.The 2nd method, you supposedly can add the Loader.content; however, it appears you can only do this once the content has completed loading, so you need to incorporate an event handler with the contentLoaderInfo object:
Code:
var myLoader:Loader = new Loader(); var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf"); myLoader.load(myURLRequest);
[code]....
What are the pros/cons of adding the entire Loader object, as opposed to the Loader.content and vice versa?
im working on an image viewer and im loading an image to a loader and then add the loader to the stage.I want the user to be able to drag and drop the image but since it's a loader i dont know how to do it. I tried
at the current status of my project i must write an application (With AIR or ZINC) who its job is:
1st-getting some files from user. 2nd-modify them with an algorithm (encryption or encoding or changing byteArray) to simply corrupt the file and make it impossible for other applications to read the corrupted file!
Is there a way to write a UTF-16 string into a ByteArray in Flash/AS3? Basically I have a string (var test:String="allan"; for example) and I would like to write that into a ByteArray with UTF-16LE encoding. In this case it would be "61 00 6C 00 6C 00 61 00 6E 00".
I've tried using utf16le.writeMultiByte( clipText, "utf-16" ); but it just comes out with what appears to be UTF8 (or just straight ASCII given the test string).
The use case is to save a UTF-16LE file using FileReference.save(), which I understand I can do by passing it a ByteArray with the correct character encoding in it. Passing just a string saves as UTF-8. Hence the need to convert and store into a UTF-16LE representation in a ByteArray.
I am trying to serialize a Bitmap to store in an XML file. My plan is to turn the BitmapData into a byteArray, but I haven't been able to fine an example of this.
i'm using AMFPHP to stream content from my server to my Flex application, since Flash is a clientside technology i would like to make it harder for people to grab protected files, so i created a system that streams swf file to another flash player, i've done all the testing on URL stream, now i want to pass the swf file to the player as bytearray .. since i think it's safer and harder to break and in the future i even might do some encryption of my own if i became more familiar with bytes and bits .. anyways is my method the best one? (SWF to ByteArray?) or is there a better one? if the bytearray method is the best, i am facing a problem in outputing the swf file in the right format, i'm using a very primitive method .
