ActionScript 3.0 :: Preloading Large Files?
Sep 17, 2010
I've built loads of preloaders in AS2 before. However I never ecountered so many problems as now. I'm confused about many things with preloading in AS3. This is my layout:I have a single frame on the first scene of my movie. The main content is inside a movieClip called container, placed on frame 1 of my next scene, which inherits from the class that holds the main code to initialize the game.(I read that this way my code will not try to access any movieClips, or sprites before they have been loaded... as they are not actually referenced from a document class).However my 1st frame where I have my preloader takes ages to load... My first question is... Does this happen because the loading procedure is different now? Or has it always worked like this... so that would mean that as I have many heavy assets in my library that are meant to load on frame 1. (Exported for actionscript in properties).I have a blank movie for a while. I'm using a simple code:
stop()
import flash.events.*;
this.loaderInfo.addEventListener(ProgressEvent.PRO GRESS, Loading);
[code].....

I have a client that I have developed a trailer for their project. Its a swf and at certain keyframes large videos play, the my listener tells the time line to continue on its path, and eventually hits a new large video.
These videos are not playing very well for the client, when they start typically they stutter.
Client is mad now and I need a solution. I am using actionscript 2.0 . How can I have each flv loadup all the way before it starts playing so it'd be smooth. I was hoping there would be a plugin or something I could buy that would show a loading bar and then have it go.

[URL]This site loads in all of the large images behind the scenes, so once you click through a project, the images appear immediately.

I was messing around with some old examples, and I ran into an unfinished example where several 30k-100k XML files are loaded and stored as a string into an Array. The code looks basically like:[code]Basically, when I trace the 'this', the order of the files that are loaded is off. Out of about 10 tries, about 3 times the order is perfect. The remaining 7 times, the order is a bit off. Does anybody have a suggestion on how to ensure the files are loaded prior to the next file being loaded? I tried placing a while loop that basically delays the clock for a few milliseconds, and that didn't work either. Besides, that is not really a good solution to arbitrarily waste clock cycles.

Can't get this to work, and it only sends out an output error. The zombies.swf file is in the same directory so I'm clueless
import com.greensock.TweenLite;
import com.greensock.easing.*;
var loadBox:Sprite = new Sprite();

I have created a flash game which is about 11 MB in size and i have created the progBar in the first frame of the swf...
But it only shows the loading process after few MBs of data beign loaded...which might take some time and cause the user to close the tab..
I dont want this to happen...How i could tell the user at least that the swf is loading without any percentage and all the animations.

What are, nowadays, the best practices for uploading a large file (which may cause a timeout) with ASP.NET Web Forms and/or MVC? Increase Server.ScriptTimeout (only for the specific POST request); Use some flash client-side uploader like swfupload ([URL]) or plupload ([URL]), but Flash uploads have some issues with proxies; Use some gmail-like javascript (like [URL]

I have a site that deals with large video files (sports videos). The site allows users to upload any source file, but most of the videos come from DVDs. I am currently using a modified version of jumploader to encode and upload files to the webserver with an HTTP request. The jumploader is a java client, and looking at my webstats, only about 75% of my users have java installed.
What I want: I have looked for a flash based uploader that transfers a byte stream to a server. Byte streams would be ideal so I can capture partial videos for failed uploads. I have also looked for flash-based ftp clients, but I haven't found anything promising. There are some flash-based uploaders that post via HTTP, and I'm considering this. I do not want to use a simple file post. Some upload methods also put the full file into memory first, and this obviously is not an option for me.

I'm writing a small mp3 player. It reads the playlist from an xml file, then at the end of a song (or when the "Next" button is pressed) automatically plays the next song in the list.My problem is that if the song is a large file (around 16MB), the player doesn't play the song -- I have to click pause then play a couple of times to play it.
The code is roughly:
Code:
function playSong():Void
{
tune = new Sound();
[code]....
where 'tunes' is an array of paths to the file. I've missed out a couple of things, but that's basically it. Is there an issue with loadSound needing to load some of the song first?

I have to work with arather large XML file (about 25Mo).From that XML file (which I CAN'T touch in any manner), I actually need only a couple attributes in each nodes.Parsing the whole XML to load the data will (of course) lead to a "A script in this move is causing Flash Player to run slowly..."Ideally, I would like to browse the XML, only parsing data needed (like you would do in a database...without having to load the whole database before ;-)But I think this is not possible? Isn't it?So, I was wondering: why shouldn't I treat it like a text file, reading it and taking only the info needed from the file?The problem is that I don't exactly see how to do ;-)Following is a copy paste of the first node only...how would you do to read this text and put in an array:name, cloneof and description?etecting the node name, checking that it exists(i.e 'cloneof" isn't present in each node), and filling the array with the value
Code:
<game name="puckmana" sourcefile="pacman.c" cloneof="puckman" romof="puckman">
<description>PuckMan (Japan set 2)</description>

my site pretty much work like a slide show. the navigation (6 buttons) takes you from one place to another, moving the content back and forward. The problem with this, is that pretty much all content have to be loaded from start, sometimes when the page loads slow or you are on a bad connection, you get transported to a blank page, since that swf haven't been loaded yet.I'll give you my structure also.[code]If i could combine these two scripts, i think i could get the solution i'm looking for.

I'm an audiovisual interactive design student on a school that's screwed up. We work projectbased and this particular project requires a lot of flashstuff. But, we don't get taught anything by our teachers and we're supposed to find out ourselves once we need something with google and the likes. I wonder what I'm paying my schoolfunds for..Anyway! I'm working on my last project this year and it's an interactive DVD for our yearbook. On this dvd, several projects of students is displayed.
I've made a root.exe projector file that's small on size and only displays a picture, some audio and a button that activates another .swf with an animation to the next screen. I load this one with the loadMovieNum command. After this animation, it will load a new .swf (again loadMovieNum, and in the new one unloading the layer below it) with many active buttons and animations.. it's the biggest .swf I have and I don't think I can split it up.Locally.. everything works just fine with hardly any pauses between the files loading.When I test it on a dvd though, the wait time is about 5 seconds and flash seems to be freezing. This is because of the lack of a preloader and reading speeds of a dvdr driveI've been looking around for preloading external files and I've read alot about them.. and tried alot too, but I can't seem to get it to work. I believe it's because I'm using loadMovieNum instead of loadMovie. I tried changing the way it's reading containers to levels, but that doesn't seem to work.

I have a site at www.asylumartists.com , and when you enter the site, it says its loading 23 files. Inside my site swf there is around 12 videos on the main timeline, and each of them are flv components. Also my external swf files are being preloaded with:[code]If you go to the work section and check out a work, it doesn't start to preload right away. This leads me to believe that the content is having trouble starting because its trying to load so many files. Does anyone know a code that stops all loading at a certain frame? Once my site loads, it just stops all cache entrees, and when you select a work it preloads as it should?

Is it possible for in a website to start loading a file after it's loaded the initial setup, so that when the user clicks to see the larger file, it's already loaded, or at least part of it's started loading, all without totally stopping other basic rollover functions and so on that appear with the initial setup?

I need a flash uploader, to use it in my CMS project. I need something like this, but with greater max upload size (it doesn't allow to upload files larger ini_get('upload_max_filesize')).
My server doesn't allow me to overwrite ini settings, so I'm looking for an uploader which can upload large files independently from the ini settings.

I'm working together with some designers to build a project in flash CS4. They normally send me their work as either jpg's or png files. When importing a sequence of png files I find that flash slows down considerably... but not only that, when I try to copy and paste a symbol that contains transparent png in their timeline it crashes. For instance if I select a frame which contains a movieclip with png's inside from the general timeline, and try to paste that frame on another layer I will get a message of Flash stopped working and eventually it just closes down. I tried this on a version of Flash CS5 and it also has the same problem but worse, as soon as you press Control + C the whole thing closes down. I'm suspecting this is caused by large transparent png files, but I'm not sure.

I built an uploader which works fine on decently sized files.
When I upload say a 2mb picture however, everything appears to be working fine - all the progress indicators, on completes operate as usual.... but then the file never shows up on the server?
I realize this is pretty vague, lacking code examples, but I just wanted to kind of put a general question out there, see if anyone suspects anything right off the bat..
ie, is it maybe something more wrong with my server? flash dosent have some upload limit i dont know about?

I have been playing around with this for few days and I am about to give up.. I want to be able to preload anythything thats being loaded to a certain MC. but I dont want to have to set any VARS in the file thats being loaded to indicate its done loading. I could make each swf thats being loaded give a var stating its done loading and make the loader gone.. but I want to be able to preload any swf.. mp3.. jpg almost anything that I load into the target.. Let me know if anyone has created something like that before..

I am trying to preload dynamic swf files from an asset folder into a blank movie clip within my main swf file. Some of the files are 2+ mb and need to preload.
I am dynamically importing the swf files from an external asset folder into a blank movHolder movie clip on the stage of my main movie. I have this working fine. I am having a hard time knowing where to place the preload script (in the asset swf or in the movHolder clip), and whether or not my script is accurate for this procedure.
Inside of the movieHolder clip, I placed the preload script script on frame 1:
totalBytes = Math.round(getBytesTotal() / 1024);
loadedBytes = Math.round(getBytesLoaded() / 1024);
percentDone = Math.round ((loadedBytes / tatalBytes) * 100);
framesloaded >=100) {
gotoAndPlay("start");
}
On frame 15 I have a looping action that tells flash to gotoAndPlay(5); as it loads the asset to frame 100.
On frame 20 I have inserted the label "start".
Obviously my approach is flawed and does not control the dynamically loaded asset. I am assuming that the asset swf if loading on frame 1 and ignoring my code.

I'm working in Flash MX
I made a site completly in flash.
But to lower file size I made the each section a different swf file
when you click a link you will have to wait for that section to load, it would be good if peoples can see the loading progress while they r waiting.
And i hav added a preloader in each of the external swf file.. and then i realise that if i wanna change or modify the preloader, i will have to change all the preloader too.. this is really kicking axx..
is there a way where on the main page there is only 1 preloader needed to show all the external swf files loading progress? i am using an empty mc as container to load thoose external swf files..

I've run into some problems trying to handle large text files in AIR (300+ MB in size). I can open a filestream and read the file just fine and even store it into a string variable. the problem occurs when i try to manipulate this data. Im trying to get each line as an element in an array so i can manipulate this data.Here's what i've tried:1. read the file into a string variable and perform a split looking for the newline character ). this freezes the program2. i've tried reading the file in one byte at a time and putting each line into an array AS it is being read from the filestream. This not only takes long but eventually freezes.
3. i've tried splitting the final string variable which contains the entire text file into chunks to process it separately.4. i've even tried putting the file contents into a sqlite database, but this also freezes.At this point, im not sure what my options are. Is AIR even equipped to manipulate data at this level? I could use a point in the right direction

My company is working on a casual game which is entirely made in Flash. To speed up development/compile time we split some of it up into SWC files, for example dialog controls, cutscenes, particle effects are all controlled via SWC files. This was working great up until a few days ago, we have been working on this project for about 8 months with no major problems. However, now all of a sudden, when we compile the game, none of the SWC files work. The game compiles and runs ok, but nothing from the SWC files are working.
The strange thing is that if we remove one of the SWC files from the folder (the game reads all the SWC files from one folder) then the game will work. Even if you remove a SWC which isnt immediately used by the game it will still work. It's almost as if there is some limit to how many SWC files you can have loaded. (There are only 10 SWC files in the folder we are loading from).
