ActionScript 3.0 :: Loading Bitmaps From The Library?
Feb 11, 2009
I've been learning AS3 for a while now, and it's my first Actionscript language, but not my first coding language. I've learned a lot so far, but I started off doing things in the not so efficient, or correct ways. I was putting all of my actionscript on frames. I'm trying to get in the habit of doing it the right way now. But I'm having a basic problem. I can't figure out how to load a bitmap from the library in AS3.

I have a large number of bitmaps, all of different shapes and sizes, and all with associated data (i.e. name, description, cost, weight etc). I want to get all these items into AS in a data structure.Based on what I know I could put together an XML file and parse that and then load each bitmap individually, but that could be very slow as it would mean loading lots of little bitmap files one at a time.I could put all the bitmaps into one big bitmap and store their xywidthheight in the xml as well so that I only have to load one bitmap but that seems a bit tricky, especially if I need to add or remove items.
I could embed all this into a class and have it load everything at compile time which is ok but not very friendly to people who aren't programmers and or don't have the source file to recompile.Is there something i can do using maybe flash to create bitmaps with additional properties and put them all in a swf that would be easy to edit by anyone using point and click?

I've been attempting to attach bitmaps from the library in AS3, and have settled on a piece of code which works:
PHP Code:
var myBitmap:Bitmap = new Bitmap(new pic1(0,0));
myMovieClip.addChild(myBitmap);

Ok I wrote an application where I have panels that the user can draw on, kind of like paint, but they can create panels. Now I want them to be able to save and load their work. Using Quasimondo's bitmap exporter, I was able to save a bitmap (200x200), and the application prompts the user where they were to save the image file. However, my problem is that the user will probably have 6-12 panels to save, and so I want the program to save all those panels so they can be loaded later.
Now in order to load, I don't want the user to manually select each panel to load. I want the user to select one file and it will load all the images into the panels. I was thinking about maybe loading a zip file and flash would extract the images and load them, but I don't know if that's possible. I think the user would need to select an XML file,which would direct Flash to what files to load and in what order. For this, and I'm assuming when it saves the flash application/php, it would need to write a new xml file.So I guess what I need to know how to do is:- How do I get flash to save several images to the server or the users hard drive- flash to generate an xml file- is there any way to make flash combine all the files into one file so that the user doesn't have to deal with several files?

To do this does it mean that I have to store them in another external location rather than my library and only load them when I need to use them from a URL request?

I want to load .jpg images into flash and store them as BitmapData objects. I've coded the loading of images many many times but I've never tried to store them as BitmapData, I just usually add the Loader to the display list and manipulate the image through its loader.
I feel like this is a very poor approach and so I want to try just saving BitmapData, because on the Model side of things thats really all I need.
Now the only way I have found to extract BitmapData from a loaded JPEG is to load the JPEG and upon completion write:
myBitmapData = Bitmap(loader.content).bitmapData;
First, is there a way to extract the BitmapData without encumbering the code with the Bitmap class? In other words, is there a way to extract that information without involving the Bitmap class - BitmapData while useful for a Bitmap is not dependent on Bitmap so ideally I would never involve Bitmap here.
Also, why is this Bitmap type-casting so widely accepted? loader.content is a DisplayObject and therefore is not necessarily compatible with Bitmap. Further, for all Flash knows we just loaded an SWF and as far as I know you can't typecast that to a Bitmap.

I'm trying to figure out the best way to compare a single bitmap against perhaps an array of saved bitmaps to see how close of a match it may be to any one of the bitmaps stored in the array. Right now I'm running a for loop that uses the bitmapData.compare() method to try to compare to see how much of a variance there is but... to be honest I'm at a loss as to how to use the resulting data to do so. Does anyone know of any good method to accomplish what I am trying to do? Forget looking at my code it's a waste of time because simply, it's not working.

I have 2 questions regarding bitmaps. Say I'm loaing graphics from a game off a server into a .swf file:
1) Which format is the best to use - gif, jpeg,png? (for non transparent images)
2) When a user plays a .swf movie it gets saved to their browser cache and its loaded the next time they access the same file, but when your externally loading images does flash have to re-download all the images or is it all stored in the browser cache?

My problem is that I want to store the loaded pictures, which is giving me trouble. When I try to trace the bitArray length, it says it is zero..

I have my .fla file and .swf file in a folder on my desktop
i want to add to that file a bitmap. everytime my flash project receives a the String "loadBITMAP" i want it to reload that bitmap into a designated area on the stage. (i am using a system of binary sockets to recieve data, but don't worry about that...i know how to process that already.) so basically my code will say
Code:
if(socket.readUTFBytes="loadBitmap"){
need code here on how to load bitmap

BTW, this should be in actionscript 3.
What's the fastest way to dump your data (not in a file) into a bitmap for display?
I had it working with setPixels and colored rects but that's way too slow.
Is there a way to load in the raw bytes or hijack the loader class to put in custom loader data?

I'm trying to clone / duplicate an object loaded in at runtime via the
--
ldr = new Loader();
var mRequest:URLRequest = new URLRequest(targetFile);

technique. The problem I think I'm having, is in understanding what exactly the loader returns and how it can be used. after loading an image and tracing the result after the loader completes like this ...
trace(ldr.content); // - traces [object Bitmap]
I have a fuction I built that returns an arrar of clones / duplicates of a passed bitmap ...

I've been quite frustrated over a very simple flash program I have, where I try to use code to add an item from the library to the stage. I've attached the .fla file. The errors I'm getting are: 1046: Type was not found or was not a compile-time constant: playerShip. 1180: Call to a possibly undefined method playerShip.

I'll do my best to keep this question as short as possible:
I've made 5 'fruit' movieclips and they're in my library.
And using so.addVariable("getNumber", "003"); in my HTML code, I'd like those particular fruit movieclips to play one after the other (and then loop).
I've had a look around for something similar, without luck, so I'm trying to make it from scratch. I got as far as getting it to load the first number and then the first type and url, but I'm stuck on getting to go onto the next type, also being able to define (with addVariable) which number's nodes gets played.
Here's an example of my XML to show the structure.
Code:
<?xml version="1.0" encoding="utf-8"?>
<list>
<number="001" >

I need to load a movie clip to the stage from the library. I also need that movie clip to load with a certain string of actionscript code in it. To load the movie clip, i checked the "export for actionscript" thing in the "linkage" section of the movie clip info, and i named the class "sol1"
I then used this code on the first (and only) frame: Code: _root.attachMovie("sol1", "NewInstanceName", {_x: 50, _y: 100}); It seems to work, but the question is, how do i load the movie clip with code in it?

I have built a flash animation (for a web site) that requires a number of decent quality JPG images. I don't display all of these at the start, so I don't want to wait for them all to load before starting the animation. Thus I want to be able to load these images in the background - the obvious process would involve MovieClipLoader.loadClip() method. This works fine if I am loading into an INSTANCE of a moveclip (either existing on the stage or one that I creat in actionscript) - but I really want to load into a library movieclip.
The problem is that I end up using these images in two different movies on the stage - each pulls from a movieclip in the library (that contains the image I want). So my original thought was simply to load (using loadClip()) into the library movie - which in turn would show up in the two stage movieclips that have this library clip in the timeline. However, I cannot seem to get loadClip() to work with a library object.
I tried exporting the library movieclip to actionscript (giving it a name) - but loadClip() doesn't seem to want to load into it. I can only get loadClip() to load into an instance that exists on the stage.Sorry if I am asking a stupid question - I don't do a lot of flash programming - although I have extensive programming experience in other languages.

I searched previous posts last week about this and learned that I can load a movie clip from the library in a blank mc holder similar to how I load an exernal swf. But so far that code is not working for me. I also need a way to close/make invisible the clip on user clicking an X. I have a page with about 6 key words over which I will place invisible buttons. First button instance is named compworkBtn. I have a blank mc on the stage, name of mcLoadertop. My mc I want to play is in the library and named compworkMC. I read that I need to set the properties to export and I have done this (picture attached for compworkMC).
[Code]....
Then I want the user to click on the X or close button and it goes away. I thought the easiest thing for this work be to program the Close button itself to drive the MC to a frame that had no content. It will still be there, of course, but not be visible. Then the user would click on the next key word and the next MC will load. Not sure that is a good solution though, because they will both still be there. So, I'd like a suggestion for another solution to unload the first mc and load the second one. I have done a similar thing with external swfs, but I will need a close button instance for each of the unloads, right?

I have several buttons that on mouse over will load a library movie clip. I want that movieclip to load on top of everything then once it's played allow me to either replay that movieclip by hovering over the button again or play a different movieclip by hovering over another button etc etc. with the ability to repeat this.
My code below currently loads my movieclip on top in hte corerct place however wont allow me to hover over another button and only plays once: var my_packages_mc:MovieClip = new packages_mc();var my_treatments_mc:MovieClip = new treatments_mc();

Have buttons on the stage that when clicked, load a mc from the library into an empty mc on the stage. If another button is clicked, the loaded mc fades out, then a new mc from the library fades in. I've got it working for external .swf's loading, but I'd like to use mc's from the library.I think I need to use a attachMovie in there, but not sure how.
ActionScript Code:
var LoadMe = "";// this is just a var to store the page you want to load
// --- >> EXAMPLE FRAME CODING FOR A MC BTN
_root.homeBtn.onRelease = function() {

I'm currently having trouble with the file size of my latest project. This due to the file size of certain movie clips in my library. This obviously causes a long preloading time.
To get round this I thought I could load these movie cilps when I need them so the user can proceed normally until they appear. These movie clips have a linkage with 'Export for Actionscript' selected but I haven't selected 'Export in first frame' because I want to export it later when they're needed.
how to ignore loading these movie clips until I tell Flash I want them loading. Bearing in mind these aren't external .swf's.

i am trying to load movieclips from the library using an array. I have manage to load a single movieclip using
var myArray:Array=[];
myArray[1]=imagex1;
var mc:MovieClip = new myArray[1];
addChild(mc);
but now I've tried using a loop by doing
var myArray:Array=[];
for(var i:uint = 0; i < 8; i++){
myArray[i]="imagex"+i;
var mc:MovieClip = new myArray[i];
addChild(mc);
}
and i get the error:
