ActionScript 3.0 :: In MVC, How Should Already-loaded Data Be Handled
Sep 3, 2011
I have an AS3 application and I'm trying to implement an MVC framework.On the model's initialization, data is gathered about the user. When the user clicks a button, say to print their first name, I want to request and retrieve only that data from the model.I currently have the view listening for a button click. The button click is handled by the controller. The controller fires a "getUserFirstName" method in the model. I'm confused about this part...Since the controller and not the view is calling the method, I can't do a return of the user's first name in this method. Should I dispatch an update event? I'm not sure how to pass this data to the view in the most efficient way.

I have a bunch of flvs that I want to play seamlessly. I figured the safest way to ensure a seamless playback was to preload the files first using a class called bulkloader. Once they have all loaded I start using the flvplayback component with .load() on mulitple vp depths.
My reasoning was the second time the flv file is requested (through the flvplayback.load method) it has already been cached in the browser cached from the previous call so it will be pretty much instant. When I test this with Charles proxy (throttled but with caching allowed it makes two calls for each flv and both are requested from the server ignoring any caching.
I wonder if there is a special case where flv's don't get cached. The bulkloader class uses a netstream object to download the video and I wonder if that has different behaviour to a loader object when it comes to caching.

Is it possible to delegate heavy computations to be handled asynchronously (on the user's machine)? When it's done, I could just fire an event, catch the new data, and update. I have played with this for lesser operations, by just setting up a que and only handle a few operations per frame; but is there another method? That feels like a heavy handed workaround, and it won't scale with faster/slower machines. IE: 12 operations per frame works fine on the test machine, but my machine can handle more, but won't do it because it's hard coded.

I want to be able to get the ID3 data tags from the mp3 that has been loaded into the soundChannel. I cant see a problem as far as getting the data using trace, but how would I go about displaying this information on my flash document, in a specific location? The data I wanted to include was the title, artist, and the duration.

I have 2 swfs. One of them called "main.swf" and the other called "test.swf"
Main loads test using the code below
ActionScript Code:
//create loader and url request
var contentLoader:Loader = new Loader();
[Code]....
What I'm trying to do is to trace the x-coordinates of a Movieclip called "dot" inside test.swf.
But I keep getting the error: "1119: Access of possibly undefined property dot through a reference with static type flash.display:Loader."
How do I get the x coordinates?

swf file A gets loaded into swf file B. swf file A allows a user to sign up for a promotion which uses URLLoader to send data out to an external domain. the external domain has a crossdomain.xml file which does get loaded, but I continue to get Security Sandbox Errors.Is it allowed to send data from a loaded swf file (swf file A) to an external domain?

I have two classes: Level, which dictates a tile-based level, and MapLoader, which loads a text file on my local machine.I am calling a load function through Level asking MapLoader to load, but when I try to parse the data, MapLoader isn't done with the load.I've tried putting the load in a while loop, but it just freezes. Here's the MapLoader and the function in Level.[code]

- I have an array of ~200 buttons. - Each button pulls individual info from a file online:
/routes/801/
/routes/802/
/routes/803/
...- My pseudocode looks something like this:
Code:
var myURLReq:URLRequest = new URLRequest("/routes/"+butNum);
var myURLLoader:URLLoader = new URLLoader();
myURLLoader.addEventListener(Event.COMPLETE, infoLoaded);
[Code]....
My problem is this: Let's say the user clicks 5 buttons. Since data doesn't load immediately, I can't assume infoLoaded is being called in the same sequence in which the user clicks the buttons, but I need to know which file just loaded. Is there a property I can get from ev:Event so it'll give me the URL I used to load myURLLoader?

I have just started with creating Drawing Pad, which can save and reload the image drawn once. I have completed the basic interface which includes drawing and erasing part. I am storing the co-ordinates in a text file. I am using MultiDimensional Array to store X,Y co-ordinates. But now I am facing a problem that how to load these variables into the flash back and using these redraw the image. I tried using 'loadvars', but it didn't helped me as it doesn't return string data. Can somebody help me in this so that I can load co-ordinates from text file and redraw the image.

I'm trying to load data from an external textfile, called "config_flash.txt". It works perfectly if applying the fetched data is done within the same function where the loading is done. However, I would like to use the fetched variables in other parts of the script.
Here's what works:
Actionscript Code:
var varLoader:URLLoader = new URLLoader(new URLRequest("config_flash.txt"));varLoader.addEventListener(Event.COMPLETE,
[code]...
So, basically I want the variables/values defined inside the function to be available anywhere in the script. The error that the second code snippet causes is as follows: "1120: Access of undefined property text1/text2".

Is it possible to access the properties of an image when it's been loaded in to an swf?
I am thinking of the properties which can be edited and displayed in the Windows directory listing.
The image 'contents' field could then be used as the caption for the image viewed in flash.

if I load data into a swf file using URLLoader (such as an XML file of a CSV file from another website), everything works fine until I actually upload it to the internet using my cheap, wimpy, webhosting service. At which point none of the data is transferred. Is there possibly anything about security sandboxes that completely eludes me, or is this even an issue that deals with security sandboxes?

I'm attaching an MC to the timeline and within that attached MC is a LoadVars.sendAndLoad command. This works flawlessly when I have a few variables but becomes horribly bogged down when I have to send (and receive) lots of data. It actually freezes my swf until all the data is loaded, then switches windows <minimizes itself in Win XP> after it's all done loading. I need a way for the original attach movie to finish loading, before I send the PHP commands...

I got another XML gallery thrown at me this week and am thinking of adding a new feature.When a user clicks on a gallery it will load the first image, and continue to load all of the images so they won't have to wait each time they hit next, as it would be in their cache. this link has been thrown around a lot, but I don't think this feature (which is an awesome feature, oh yes) has been addressed. Goto one of the galleries and wait for it to load, and then keep hitting next. The pictures load before you get there. You can catch up to the unloaded ones and reach a loader bar if you hit next enough times

I need to clone .png image data loaded from server in AS3, so that I am not required to load same data again and again from server. After a search on cloning image data in AS3 I was able to find following code over internet clone = new Bitmap(Bitmap(this._loader.content).bitmapData.clone()) By using this code I am able to clone bitmap data but the problem which I am facing is that my png background is transparent. If I typecast loaded png data to bitmap my icons background becomes white.

The problem is that it executes #Second before #First, which means that the object is not fullly loaded but the code continues nonetheless. Is there a way handle this? I have tried using a while loop, but this is ugly and makes flash crash. Is there any decent way to handle this, does it have to do with better code structure/program flow or is there a technical way to make it wait? Also note: This code is executed on the server side, which means there are no frames involved.
UPDATE:When projects get bigger, this gets very ugly, especially when you are retrieving mulitple things from a server, you have to use very deep nesting, you have to keep repeating the same code, example for buying a serial:
a.onload() {
if(moneyAmount > 10){
b.onload(pay) {

I have successfully loaded XML data into a SWF file and am able to get values from the XML without much problem. The code works. For example my test productimage[1].toString(); is returning back the correct value from the XML file.My issue is when I load this SWF into another, a preloader, the code no longer works? The preloader is working fine and the rest of the SWF file is loaded in succesffully, even the XML data appears to be working when I run a trace i.e. trace(e.target.data.toString()), but for some reason the individual data values such as productimage are no longer being defined??]code]
