ActionScript 3.0 :: Loading And Progress Bars In Flash?
Oct 8, 2009
Somebody should write a book about loading and pre loading assets in flash !Im loading a few images using a loop and i store them in a bitmap array.I want to find the proper way to create a progress bar.I think i need to calculate the totalBytes of all the images but i need to it before i load the images....Is there a way to get the file size without loading the image ?That way i could create a loop that will calculate the bytesize of all the images and store it an a variable.and then i could just divide the total bytes with the current bytes of the image and get a progress bar the will represent the exact loading time.

I am working on a portfolio site to display images. I have 2 frames, the first contains a progress bar and this code:
[Code]...
The second frame has the content and different action script that is related to it.
My problem is that the whole site works fine in Flash when i "test movie" and "simulate download" but as soon as i "publish preview" in either flash or html the progress bar doesn't work, it just freezes on that frame.I am really new at this and have just pieced together the code i have from various tutorials on the net but this is really testing my patience. So frustrating because the site took me ages and it looks great in flash, just need to get past this little hitch.

Has anyone seen the issue with the progess bar, when uploading on a system running Windows 7.The progress bars show 100% immediately as the upload is happening, and the site looks like its frozen out - but its not, the upload finishes and the onComplete event is fired! So the upload is working, but not the progress bar.I am not even sure who's problem this is... is it MS, or Adobe

I'm using ActionScript 2 and I already placed the progress bar on the stage assigned it the instance name ProgressBar0 but i'm confused on how to give it a label, have it start at a certain time and end at a certain and show the percentage complete in the label.

I have a loop that parses and works on a lot of data and it takes a long time. While it works away, the screen is blank and im wondering if there is a way to put a loader or counter up?
Since it does a finite amount of work, I thought I could just update the progress from within the loop but further readings has revealed that it wasn't possible.

I am building an ActionScript 3 loader,which display the progress of Flash loading an external script. Here is a snippet of my code that works perfectly.
this.SWFLoader = new Loader();
this.SWFLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, trackProgress);
this.SWFLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
this.SWFLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, loadError);
As you can see, I have three event listeners, each for listening for different events triggered during the loading process.In regards to the above snippet, here is what I am unsure of:
What is the contentloaderinfo object?
What properties does the contentloaderinfo object contain?
Why can't I just use this.SWFLoader.addEventListener()?
When is it appropriate to use contentloaderinfo?

I've created a progress bar animation to load an external SWF file as described in this document: [URL] The problem is, the SWF file i want to load is a magazine exported from Indesign, so I want it to display one page (frame) at a time (you can go to the next page using the navigation buttons provided). When I use the method mentioned above the clip loads, but then it plays... so how can i make it stop at the first frame?

My application has a couple of modules which am loading as thus in my application.
<local:moduleloader url="Module1.swf" id="modulel" />
<local:moduleloader url="Module2.swf" id="module2" />
Then while loading each module I am showing the progress bar. The progress bar shows but does not go away. It remains above the whole frame of the application. The module loader is as follows:(Also note that in Flex 3 the same works, but am using Flex 4 and in Fx 4 it does not)
<mx:ModuleLoader xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"

I'm trying to make it so that the first 99 frames of a 198 frame preloader run even when the swf is loaded into the cache. I have the script looping the second 99 frames of the preloader while the movie is loading, but when it's already loaded, I only want the first 99. Right now, when the movie is already loaded, I'm only able to skip over the preloader altogether and go right to the movie OR I can see a loop that starts at the beginning of the preloader and then cycles through the second 99 frames indefinitely and never goes on to the movie that's loaded. At first I was using two separate movie clips, one for the first 99 frames and another for the second 99, but since that didn't work, I combined the files to see if that would work, but it didn't. I've tried so many adjustments, I've run out of ideas. Is it even possible to use a conditional with the onComplete function that's supposed to run when the loading is done, so that onComplete only happens if the current frame of the preloader is greater than 99?
Here's my script for frame 1 of my movie. The movie proper starts on frame 2, and preloader is the 198 frame movie clip in the library. The result of this script is an endless cycling of the preloader even when the movie's loaded.
stop();
preloader.play();
function everyFrame(event:Event):void

Okay I made a photo Gallery using a Loader in the Components tab. I'm making the different frames load different pics (changing the Content Path of the Loader on each frame) so now when I go to my gallery after uploading it to the web then it takes a while to load the pics...so what i want is just to show the people that the photo is loading and that its not nothing on the gallery.

I have a swf called "main.swf". Here I am using movieClipLoader to load another swf called "news.swf". In "news.swf" I'm loading several images using movieClipLoader.
On the "main.swf" I want the loading progress for the ENTIRE "news.swf", including the loading progress for the images.
If I use onLoadProgress for "main.swf" while loading "news.swf", it will reach 100% before the images has started loading. I want the image loading to be included in the progress.

I have a situation where I'm using the FLVPlayback component and it starts off blank, meaning that it shows the video player skin but doesn't load a movie until prompted to do so. However, the progress bar in the skin is acting as if a movie is being loaded. I'd like to make it invisible or stop it until I need it, but I can't seem to target it. I've tried the following with no success.[code]

I'm having quite a hard time with trying to use the UILoader& Progress Bar components together, to make my thumbnails &main images load. The slideshow consists of 6 thumbs, each loadedinto a UILoader component, and held within a movieclip calledthumbs_mc, which is animated to appear as if its moving up a path(starts really small, and enlarges toward the user). I've foundthat the animation will not work unless the UILoader components arecontained inside of a movieclip.What I'm trying and failing to do is monitor the loading of the thumbs, so that they won't start movingdown the path until they finish loading. So far, what happens whentesting live is that the thumbs skip the animation and just appearin their end positions. I can't seem to get the Progress Bar andthe UILoaders inside the thumbs_mc clip to work together.
Once I've figured out how to do this, the next step would beto load with UILoaders and the Progress Bar each of the largeversions of the images, when the thumbs are clicked. But for themeantime, if I can figure out the thumbs, I can probably figure outhow to apply the same technology to the loading of the main images.

I am attempting to monitor the progress of an image scroller I've built and all of the images (thumbs) load separately. What would be the best way of figuring out what the total progress of the images that are loading? I was thinking it would be cool to use a generic loader and apply it to a function such as
myScroller.loadImages();

i have build a flash project where most of the content externally loads in to the main movie. for each chapter i made a "Loader" component, and a "progressBar" connected to the "Loader". during building i was re checking that all is working well (test movie with "simulate download"). then, i was uploading it to my server and when i view it on "fireFox", or "Safari" , it all working. but, when trying to view it on "IE", i never see the "progressBar" and, all the Actions that relate to the "on (complete) {}" never happens.

trying to load a JPG. Here is my code:
import fl.controls.ProgressBar;
var pic_loader:Loader = new Loader();
var my_pb:ProgressBar = new ProgressBar();
my_pb.source = pic_loader.contentLoaderInfo;
[Code]....
The image loads but it does not "take the place" of the "pic_loader" movieClip like it did in As2. The main issue is I am getting this erroe message:
TypeError: Error #1034: Type Coercion failed: cannot convert loader@40fad881 to flash.display.Loader.
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

I have built a site the loads external swfs for each page once the button is clicked on the main fla. im trying to add a custom animated progress bar (fade in, show progress, fade out, show content) for each page but not sure how to go about it. Also I am using flasheff2 and think it might complicate it a bit.

I'm currently loading an image dynamically into a loader using this script.Code:loadMovie("1.jpg",_root.sliding_content.content_2.contents.example_birds.work_page.myloader);All I'm trying to do is attach a progress bar component to this loader. Other images get loaded into the same loader component using the same actionscript as above but with different file names.I'm having difficulties getting the progress bar to show the progress - when it gets to 100% disappear and then reset and reappear when another image is loaded into the same loader component when the action script is called again.

Is there a surestarter preloader in AS3 with CS4? Meaning here, showing a progress bar or percentage value before loading the main swf, right away at the start of the loading.I tried 3 different versions:
1- I used the code from a video (and accompanying files), and simply changed the content.swf to my own swf file (rename my swf content.swf), so that the original code would load my swf instead of the original content.swf. (original content.swf was too small to see anything before loading, because my loading speed is too fast).Here is the code from the original preloader (loads a small swf which then loads the main swf file):
var l:Loader = new Loader();l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop);l.contentLoaderInfo.addEventListener(Event.COMPLETE, done);l.load(new URLRequest("content.swf"));
function loop(e:ProgressEvent):void{ var perc:Number = e.bytesLoaded / e.bytesTotal; percent.text = Math.ceil(perc*100).toString();}[code].....
