Actionscript 3 :: Manage Loaded Assets?
Jul 23, 2011
I'm working on an AS3 project that must load a lot of external files; images, sound clips, movie clips etc. The program first loads an XML file that contains the file names of all assets needed by each class. From that point on I'm not sure what would be the best way to distribute those assets.I thought about making a dedicated assets class that will load everything the XML object describes, and then pass it to each class' constructor so they can access the objects they need. This seems like the "tidiest" option, but is there a best practice way for managing loaded assets?

Due to screen density of iPhone, image assets are developed larger. So, when specifying the icons and images to Flex components takes this form.
<s:ViewNavigator id="tab1" label="Tab1 width="100%" height="100%" firstView="views.Tab1">
<s:icon>
<s:MultiDPIBitmapSource source160dpi="@Embed('assets/tabIcon.png')"/>
</s:icon>
</s:ViewNavigator>
Flex of course renders this correctly and adjusts the size to what it should be. However, when I load images myself, they appear blown up as they would appear double in size. This is how I use it when overriding the tab bar.

Can anyone explain the model for actionscript in externally loaded SWF assets? For example, suppose the stage owner uses methods from Class1 and that it loads an SWF file with an asset that also uses methods from that class. This means the code for Class1 is included multiple times in the application?

I'm trying to load a swf compiled by the Flex SDK into a swf exported by the Flash IDE and instantiate the assets by way of getDefinition(). Normally this works fine with assets exported from the Flash IDE then loaded into another swf also from Flash IDE.This is how I could normally do this using only the Flash IDE:Loader - > Using same ApplicationDomain - > getDefinition(class)Now, using the 'Test.as' compiled from Flex SDK using the [Embed] metadata tag:Loader - > Using same ApplicationDomain - > getDefinition("Test_" + class)The problem is I'd rather not have to keep track of the asset libraries loaded to prefix the class name I'd like to get (('Test_" + class) vs (class)). Is there any way of doing this without referencing the library the class is being pulled from or without accessing the original loader? This way I don't need to know which swf the asset is coming from, just the class name that I could instantiate from the current ApplicaitonDomain.

I build a project with Flash Builder. I copied everything from the "bin-debug" directory to a server (including all images we use which are under /assets).
After I have updated the project, and a few images, i recopy the primary .SWF file (Main.swf) and everything under assets up to the server again. Unfortunately, when I run the application, I am clearly running all of the updated code but the images have no updated.
The new SWF was definitely copied up as well as the new images (I can say that with 100% certainty), and additionally, I cleared my Flash Cache, so that's most likely not the problem either.

I'm making a game for the browser that has a lot of assets, but not all of them are needed at once. I'm deciding whether to embed my assets at compile time or load them at run time. I'm not concerned about loading time -- only the performance of the game during run-time.
If I load these assets and store them into memory for eventual use later in the game, will they consume system resources just being latent in an AssetLoader? Will that affect performance?
If I embed these assets, will they consume system resources just being latent in the compiled SWF?
Is there a difference in performance between these 2 methods?

I have a widget containing a number of displayobjects, i.e. up arrows, down arrows, tab 'buttons', backgroundrectangularblocks, sliders, company logos etc.I am currently creating these displayobjects using the graphics class with parameters taken from an external file, things such as fontsize, font, colour, width, height e.t.c and adding them as children of "container" sprite objects for easy manipulation and referencing later can these assets be loaded in their entirety externally, rather than being created using graphics class draw methods (which I want to avoid) as some of the things I need to design cannot be created in pure actionscript very easily (if at all?), and then used or do they always have to be in the library and instantiated from there?
if the first question is yes they can be loaded externally, this question probably isn't needed; however, if I have to put the items in the library and recompile each time a client wants to use say a curved blue up arrow instead of a yellow one and then decides he wants a yellow circle instead then how do I write the code to do the following:-Say on my first ever compile I have 'upArrowBtnset1' in the library, I instantiate it and use the instance name to access it in the usual way using standard code,
upArrowBtnset1.addEventListener.... container.upArrowBtnset1.scaleY = .3 e.t.c
Now if they send me a second set of 'upArrow' graphics they want to use I could either update all the upArrowBtnset1 assets with the new graphics meaning the original set is no longer available to the client and I would either have to hold a "original set" FLA file with the first set of arrowbuttons or I could import these to the library as upArrowBtnset2 and a third set they send as upArrowBtnset3 and so on each time I am sent some new assets; I would then recompile them into the SWF and adjust the references to the new assets within the code. In the code, for each instance of "upArrowBtnset1" I would have to rename them to "upArrowBtnset2", recompile and send it back to the client.
Because I have already abstracted the font/colour/size choices out to an external file, they can change that as much as they like without a recompile which is what we want. The problem comes if they want to use set1 again and haven't kept the original "set 1" compiled SWF. It would be easier to abstract the 'setchoice' also to the external file. The SWF would over time build more and more available sets that they could use by just changing an external variable.
For example, if the designer wants to use set 1 on Monday, set 2 on Tuesday and set 3 on Wednesday I want to make it so they can just adjust an option in an external file to "setchoice = 3" for weds instead of either having to recompile the swf each time or they have to have 3 versions of the SWF for each asset set. The idea is that as more and more assets are added in, they have more and more choices. Ideally, in an external file there would be a list of assets and links to where they are loaded from. (i.e question 1 above).
If I have an external file (say XML) which holds the setchoice option that the designer wants to use (say they want set3 today) my 'generic' code has to be something like upArrowBtn(setchoice).scaleY and every instance in the code where that object is used I append the 'setchoice' as chosen by the designer from the external file where (setchoice) is retrieved from something like var setchoice:String = "set3"; from the external file (I am currently abstracting all the adjustable variables to a configuration.as file. I will work on using an XML later when the principle of external files works (I hope!);
Is it possible to import assets from external sources and then use them in the SWF as if they were in the library? The loader class? Is this just fraught with danger I wonder.
Essentially I am being asked to remove as much as I can from the SWF so that if the client wants to change the positioning of things on the stage or the text on buttons or change the style of the buttons or the company logo they don't have to come back to us to ask for a recompile of the SWF for each tiny adjustment. Inevitably SOMETIMES a recompile will be unavoidable (such as if they want the widget to suddenly be twice as wide (i.e. the stage). My code already handles some of this using stage.stageWidth and then positioning objects relative to other objects already on the stage using this value and centred so that just changing the document properties is all I would have to do and everything else adjusts proportionally. I am trying to make this as reusable as possible with as little effort from myself as possible to save our company wasted time.
After all that waffle, my question is this, if I can't load all my buttons and assets and things externally, how do I write the code for this:- I have a library asset called upArrowBtnset1 and another called upArrowBtnset2. Instantiated with say upArrowButtonset1 and upArrowButtonset2 The code would normally be upArrowButtonSet1.x = 100; upArrowButtonSet2.y = 300; but I need it to be upArrowButton(setchoice).x = 100; upArrowButtonSet2(setchoice).y = 300; where (setchoice) comes externally from var setchoice:String = "set1";How does the code change if the (setchoice) string was named not at the end i.e 'button(setchoice)UpArrow'?
ActionScript Code:
var numClips:Number = 5;
for (var i:Number = 0; i < numClips; i++)
[code]....
I need to do something like, getChildByName("mainTab"+i).addChild(myMovieClip) ? or maybe this["mainTab"+i].addChild(MovieClip)?Is it possible without using .name?

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?

PURE MVC - In my application there are multiple screens which are minimized like in windows desktop. Now each has different instances of mediator which have same notification. So if I do changes in one screen say press some button >> which sends some command >> to proxy >>then proxy sends notifications to mediator. But as multiple screens are active there it is showing changes in all screens as they are notified too by proxies. How to make sure that proxy calls to particular view component (mediator) and not for all live instances of mediators ?

I wrot a FLA in AS3 which is basicaly a nicly designed Loader which loads little cute SWF games. Each game is built a bit differently and has its own 'thing'.I was wondering, how can I control the sound of the SWF's from the Loader File?
Which leads me to a wider issue of how can I control variables of a loaded SWF.

I would like to know how to manage timing in AS3.Let say I have some functions in a code and all of them trigger an animation.
A) I would like to run the functions one by one, but next function must not be triggered before the animation of the previous one is completed
B) I would like to run the functions one by one, but next function must be triggered certain time after the animation of the previous one is completed.

URL...The problem is controlling which are the elements to be moved, and mostly, how to manage the amount of movement. When I open a submenu, I've got to move all the subsequent buttons down. But when I close a submenu, I've got to move them up. If I'd do it in different times, no problem.

I'm creating a movie object using images. I'm using PNG file types with an alpha channel. Each frame is approx 640 x 480, each single pitch image is 36 frames creating an image 23040 x 480. If it's a multidimensional image it is 23040 x 11520. I load the image in using "img_name".loadMovie("imageFileName", 1);
The problem is it only seems to load around 2880 pix of the image.
How can I get it to load the whole image? How can I choose it to load the next section of the image?

Does anyone know if it's possible with any of the Adobe products to automate and manage streams?
We've got a project that will be streaming pre-recorded video and music. Due to the number and frequency of these streams we need a way for us to automate and manage these through our own CMS system.
We will be ultimately pushing these streams out to our CDN provider so no end user streaming actually required.

Part of a larger presentation I've made, there is some background music. What happens is an XML file is read to get a file to play. It plays. When it finishes, it reads the XML again to get the new file. It can also stop when a video plays elsewhere in the presentation then I pick it up where it left off and start the process again. Trouble is, the presentation randomly stops. The music stops and the slides in the presentation stop. The music and slides come from a single XML file. There's also a third part of the presentation (a text crawler) that never stops.
This comes from a totally separate XML file. I never get an error, the presentation just stops on a slide and no more music plays, but the crawler keeps crawling. I've removed all the code for the music and it runs perfectly so it's obviously related to how the music is managed. So, finally, my question is how do I manage sound objects? If I need to create new objects for each sound I load and play, I'll need to do manage the sound from a single function, right? Something like:
Code:
function whatever():void {
if song is not loaded {
read xml, load and play song;
} else if video is playing {
pause the song;
} else if video has stopped playing {
resume song;
}}

I have 2 AIR applications (A and B) that are able to communicate via a LocalConnection object. I've verified that messages are definitely being sent/received appropriately.
I want to be able to have A tell B to come to the front. Both applications are full screen:
stage.fullScreenSourceRect = new Rectangle(0, 0, 1080, 1920);
stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
I've tried several permutations, but as of yet nothing seems to work.
private function initSlave(channel: String): void {
conn = new LocalConnection();
conn.client = {
[Code]...
If I leave both applications in windowed mode (stage.displayState = StageDisplayState.NORMAL), then toggling alwaysInFront actually works. Calling activate() or orderToFront() still do nothing. If I try to toggle alwaysInFront and then set the application to fullscreen, the application ends up fullscreen behind my windowed app. Maybe there is an event I should wait for before setting the app to fullscreen?
I found a thread mentioning that orderToFront() only works relative to windows within the same application, which explains why it doesn't seem to do anything.
Does anyone have any insights into pulling this off? Maybe there is a way for me to embed B into application A so they are actually the same application? I am not sure how to do this with an AIR application as simply as just loading the SWF due to requiring external resources.

I'm currently working on side scroller that has an isometric-type perspective (think Double Dragon) and the only thing I could think of to use to manage the depths of the MCs was a bubbleSorting algorithm.
[Code]...
Now this works fine (because I don't have a huge amount of MCs to sort), so I guess this is more of an academic question. As far as I know, bubblesorting is pretty much one of the worst sorting algorithms out there. Has anyone successfully adapted a better one for this purpose? Not trying to get you to post your code as much as just an idea for me to play around with because I'm a geek like that.
