ActionScript 3.0 :: Preloader For Xml File And Stage Assets
Nov 13, 2008
I have a Flash app that shows a map with different regions colored depending on values in an external xml file. I also have a simple preloader that I want to appear until all the elements of the app are ready to be displayed. However, when I use the preloader, the results are the same as if I hadn't use it. My map comes up immediately with no colors, there is a pause, and then the colors come in (as calculated from the data in my xml file). Do I have to have code in my xml loader that tells the user what percent of the file is loaded?

Greetings. I am working on a website that uses flash for everything. There is little HTML ... anyway, since it is such a massive main file, the client requires a preloader. I searched for some code and inserted it. It seems to be working fine. The only weirdness is, i can't get the "Loading Module" animation and the dynamic text box used to show loading status to show up on the stage. Instead what appears there is some kind of bizzarre animation that just uses little circles as an animation. Sounds crazy i know, but you can see it at the following link.

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]....

Working on my first real project in as 3.0, trying to decide how to best work in a preloader. What I have is a single swf containing some assets, and a target to a main doc class. After loading those assets onto the stage, it runs through a routine to load several other swfs, and then 'does stuff' with them... anyway. got all that working nicely. How, now to best track the loading of the main swf? If I understand it correctly the Loader class is purely for loading external assets. well - what about internal assets?
Got this:
ActionScript Code:
//A large SWF file can monitor its download by calling
this.root.loaderInfo.addEventListener(Event.COMPLETE, func)
I think it would be called AFTER the whole main.swf has loaded. In AS2.0 i could target _level0 to get information back about the currently loading swf...
ActionScript Code:
initPercent = (_level0.getBytesLoaded()/_level0.getBytesTotal());
But, again, these are internal assets, not even living in memory yet. As far as I can tell - I need to use a preliminary (separate) swf to load the main.swf. (Like i used to do with AS2) - But if there was a method of targeting internal assets - a 'self loader' that would be cleaner...

I have a Flex application that automatically loads the SWF and it's contents and displays the default progress bar like in all Flex apps. Currently I have a class in the application using a Loader instance to load an external bitmap to be added to the stage/canvas. I'd like to handle the loading of this bitmap in the Flex default preloader and get rid of the Loader instance entirely.

I have an actions layer, a sound layer and an image layer. I put one image from the library onto the image layer and all I see is the border. When I test the movie the image is visible. This just started suddenly. What is going on? Flash CS4.

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 want to add assets like buttons etc to the xml file. Will that change the order in which the existing items will be called but the code?Right now it's this:
<image>#1.jpg</image>
<image>#2.jpg</image>
<image>#3.jpg</image>
It will be like this:
<image>#1.jpg</image>
<image>#2.jpg</image>
<image>#3.jpg</image>
<asset>#1.gif</asset><asset>#2.gif</asset><asset>#3.gif</asset>
In my opinion no change in the code should be required except for adding loaders for the new items.

I want to create something like gallerea of images. All images are defined within an XML file. The XML file itself sits in the project directory and embedded this way:
[Embed(source="xml/data.xml")]
public var testXml:Class;
The file structure looks this way

This is sort of a repost, but because this thread is in the AS3 section the subject is inherently different because this board doesn't have anything to do with Flex.So, I want to put a bunch of assets within one file (SWF maybe) and load it at runtime. Then I want to be able to access these assets after I've loaded the file.As is visible by my previous thread, I have no idea where to begin, but I know it's "absolutely" possible and obviously very useful.
Even if the loaded file isn't an SWF file, I'm fine with it. I would prefer to be able to store vector graphics in it though, maybe even produced in CS3/4/5 (because that's what my friend's using to draw said graphics).Looking forward to hearing from some of you over here--now that the thread has a more general subject.

Flash Builder has a nice feature that will allow you to have it move files such as images, fonts, xml files and so forth into the bin-debug directory an compile time. The reason for doing this would be to mock up some data or test pulling in assets dynamically but having them in source directory so you can version control the assets during development. Typically we don't add the bin directory to version control so being able to have the IDE move files over to bin for you is very helpful if you are on a large team.
Is there a feature within FDT5 that will do this like Flash Builder?

When embedding assets of any size in the following manner -
[Embed(source="../../assets/Assets.swf", symbol="LargeButton")]
public static const ButtonAsset : Class;
it looks like the resulting SWF size jumps up ~2.8KB (in addition to the size of any assets that are actually embedded).
So I have a few related questions:
Is this because flex_sdk/frameworks/libs/core.swc must be statically linked? Is there any way to get around this restriction, perhaps by cherry picking the necessary files and compiling them to a SWC file?? Note that in the app I am writing file size is critical.
Is there a command/plugin that would allow for the transcompiling of vector graphics (drawn in the Flash Professional Authoring Environment) into raw ActionScript 3 ?
Use cases compelling this feature are improved workflow - would allow designers to draw assets in Flash Professional, compile to an asset SWF, and then be able to embed those assets (versus having to take the time to load them at runtime, or going to the effort myself to write them in ActionScript).

I have built a component, but the assets do not appear in the symbol library of the destination fla when I drag the component to the stage. This is fine, except that I have embedded a font in the component. To ensure the font exists in the destination swf, it must exist in the symbol library of the destination fla.My component extends the UIComponent class, and I have a component shim, although I'm still not entirely sure of its functionI have followed all of the steps found in the 9 part MenuBar tutorial, and everything works, except for this one issue.

I am looking for information on how to best import assets from Illustrator and Photoshop to get a low file size for the final swf. In particular:I have text that has been effected in Photoshop and a few images that can be brought in from Photoshop or illustrator. Right now I am exporting for web and bringing to Flash. Looks good but file size of end swf too big. I have gotten .fla files before from so-workers that have text or graphics as shape objects rather than images - is that possible and how is it done?

what I'm trying to do is make a preloader that will preload about 20 external SWF files before it lets you get to my main file. I want to do this because my main file needs the SWFs to be ready to go once its done loading. I have looked around and i found a few ways to do this with the "if (loadedBytes>=totalBytes)" and the code loops back till the files are done loading... this would be just what i need but i cant seem to get it to work. the file just seems to start loading my files but does not loop and just runs the time-line even once i state what frames i want it to loop.

I'm creating a flash 3d website for a company. The idea is that there is one overall swf file - this holds the navigation and design. Once the user clicks on a button, it goes to frame 10, I have included the following script to load a swf file
loadMovie("deepbartesting.swf", maincontent);
this.onEnterFrame=function(){
if(movieClipName._currentframe==5){
[Code]....
the preloader works, but instead of going to frame 2 of that swf file, it goes to frame 2 of the overall swf that holds the navigation. Does anyone know how to get around this so that it goes to frame 2 in the same swf file as the preloader?

I'm heaving trouble centering the preloader on the center of the stage. The preloader is basically a rotating oval shape.
so, below is the code that for some reson puts the circle in the top left corner...
Code:
stop();
var circle:LoadCircle = new LoadCircle();
var circle_WIDTH:Number = circle.width;
[Code]....
meaning... the stage is not static, but it dynamically shrinks and expands to the size of the oval preloader...
how to make the stage "static" so that when I set the size in the document properties, centering an object in AS3 will stick to it?

I am trying to build a simple preloader. I have 4 movieclips on stage and on each one I am adding an image that comes from an xml file:
theMap = new XML();
theMap.ignoreWhite = true;
theMap.onLoad = function(success){
if (success) {
theNodes = theMap.firstChild.childNodes;
[Code] .....
Everything works ok but as the jpgs are a bit heavy I'd like to preload them. Is that possible?

Experimenting with Flash as usual.Preloader's are always something that have caused me trouble.Here's what I typically use for a timeline based preloader in AS3:
this.addEventListener(Event.ENTER_FRAME, loading);
function loading(e:Event):void {
var total:Number = this.stage.loaderInfo.bytesTotal;[code].......
I'm really interested in a preloader that loads right across the stage however - regardless of if the stage is resized.I should imagine it'll involve implementing = Math.round(stage.stageWidth); at some point?

I have come across a hurdle that I can't seem to find a way around, when calling in an external .swf file to the stage. Here is what I would like to achieve...
I have 4 .swf files that I would like to call in via 4 buttons on the stage. When a user clicks a button, a pre-loader for the file appears on screen and when loading is done, the loaded file appears. When the user clicks a different button, the current file disappears, and the relevant file is then loaded, with a pre-loader if necessary.
I have used the following code to successfully call in the .swf:
ActionScript Code:
var req:URLRequest = new URLRequest("potfolio.swf");
var loader:Loader = new Loader();
loader.load(req);
addChild(loader);
I can also attach this to a button using the addEventListener, and have it work. However, the problem comes when trying to attach a pre-loader to this, as before, my loaders have always just pointed flash to a frame, rather than display a file that is being loaded once complete.

First lets start off by adding in our stage width variable. You can of course use Stage.width, however I find this works a little better.

Of course I receive the #1009 error : Cannot access a property or method of a null object reference. I guess it is some "stage issue" but I'm not familiar enought with AS3 to avoid the problem by my own.

I am making a site in flash. Without a preloader everything appears on the stage fine. Once I add a preloader I can no longer see certain things on the stage. I know they are on the stage because I can call them through code and I traced their getChildIndex and they are the same across both files. Files w/ preloader and problem:[URL] The main file is Test.fla. The code that adds the objects that I cannot see is in Test.as and the objects that I cannot see are menuBG, menuBGL, menuBGR, menuBGB, shader, grid, and imageStatus, or anything that is imported from the library.
Edit: The problem is caused by me exporting my classes in frame 2 which is needed by the preloader. In my init() function I tried adding gotoAndStop(3);

I'm having a big of a problem, basically when I'm loading an external SWF file, I place in the stage the preloader, I have three symbols for the preloader, the loadbar, that loads across the stage, a circle animation, and a dynamic text that shows the description what is loading. Well when the preloader comes to the displayList, the dynamic text seems to fly off the stage, but when I do a trace statement of the x and y value of the text, it shows 413, but it still goes off the stage. I'm not sure exactly why I'm getting this. The dynamic text is embedded inside a movieclip, and I move the x/y value of the movie clip.

- I have A.fla.
- A.fla includes buttons, movie clips and also B.swf is loaded in A.fla using a LOADER
- i want to access elements in A.fla, from the actionscript codes inside B.fla to modify those movie clips and buttons based on actions going on in B.swf
for instance, lets say there is a button X in A.fla, and there is a button Y in B.fla, B.swf is loaded into A.fla, and I want the button Y to erase button X when clicked.
general question: accessing elements in a stage, through a SWF file loaded into that stage.
