AS3 Preloader Help.

Can someone kindly show me/point me into the right direction on as to how to make a custom preloader. But the thing is i want it inside of a URL function.. Which is where im struggling. Can someone help? Many thanks.

I don't see anything in there that resembles an attempt to build a preloader and still cannot determine what you are referring to as a URL function. One thing I will suggest is that you break up your loader code a bit so that you assign the event listeners to it before you start loading as shown below. Cramming a series of operations into one line is not always the best way to go...
var urlReq:URLRequest = new URLRequest("https://api.twitter.com/1/statuses/user_timeline.json?screen_name=Scot tMitchell");
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, loadComplete);
loader.addEventListener(ProgressEvent.PROGRESS, progressHandler);
loader.load(urlReq);
If you look in the Flash help documentation in the URLLoader class section, at the very end of that section it shows a variety of events being coded, including the PROGRESS event that I added above. That may help you get a better start on what you want to do.

As3 preloader problem - Captivate5

Hello all,
Been searching around for this for a bit in a the forums and cant find anything on it here goes:
I have a project that i built with a ToC for my company. And i have a as3 preloader as well.
Problem:
Preloader is fine and centered in the middle of my project with out a ToC but when i add the Toc the preloader will not center in my project i have tried to alter it in the html file insterting <center> tags and such and also externalizing the skin or FMR SWF also removing and placing it back in and not getting a fix for it. I realize this maybe a simple fix but i cant find anything in the forums here discribing exactly this issue.
can anyone help
thanx
bobby

Hi,
Going out on a stretch here but did you, by any chance, added external swf or widgets that would have set the values of either Stage.scaleMode or Stage.align. That could explain the effects you are seeing.

New to Flash AS3, Need help with some weird issues, have .fla link attached...

Basically, the buttons are not visible when siteplan_mc is replayeed after floorplan closes, but they still work. Most things are only working on double click for soe reason, tho I have them to function on click. and the back button only woorks on unit 1 floorplan, tho the code it the same for all floorplans. I have a feeling it has something to do with levels... but I really have no idea... hopefully someone can help!
thanks in advance,

There are at least two things you're doing wrong. You can't go to a frame where something exists for the first time, and immediately do something to it. Like in your playunit functios for example:
gotoAndStop("unit1")
unit1_mc.alpha = 1
unit1_mc hasn't yet drawn itself on stage to have its alpha set, and so there's an error. That is something that was improved in Flash 10, so if you had set the Flash to publish for Flash 10 and not Flash 9, then the floor plans and the back buttons appears ok. It would sometimes work with double clicks because by the second time you clicked, the movieclip now existed. You might be able to do what you want by having all of the room units on frame 1 of the siteplan_mc, and then set their visible to true or false as you need them, instead of doing the gotoAndStop().
The other problem is that you're trying to set listeners on the Back buttons that don't yet exist. Wait until you're on the frame where the buttons exists, and then set its listener for the mouse click.
Other things you're doing could be improved too, but really you might want to get together with someone who has done more AS3, to help you become more familiar with how it works.

AS3 need help converting

Hello everyone,
i have a site im working on that uses as2 but i need to
change it to as3, any help would be much appreciated.
Thanks

Hi again, so I'm still having a few issues, your help is much
appreciated. The snippet you gave me for the movieclip buttons
works great but there is no hand when you rollover the button ( i
can probably figure that out ). Pretty much the swf is a navbar for
an html site, when one of the movieclip buttons is pressed i need
it to go to say "work.html" but I also need it to tell the SWF to
go to a certain frame label for the down state of the button. Here
is my website under construction
www.lafrancemedia.com . and
here is the code up to date:

HELP - Add a skip intro btn to AS3 preloader

Hello, I'm a bit of a newbie to AS3 and new some help!
I've created a preloader.swf that (when loaded) loads an external swf. I would also like to add a skip intro btn, but when I do, the preloader seems to loop over and over (blinking - I know, high tech).
This is the preloader code. I have it in the first frame of the preloader.swf:
stop();
var myRequest:URLRequest = new URLRequest("flash/index.swf");
var myLoader:Loader = new Loader();
myLoader.load(myRequest);
myLoader.contentLoaderInfo.addEventListener(Event.OPEN,showPreloader);
myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,showProgress);
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,showContent);
var myPreloader:Preloader = new Preloader();
function showPreloader(event:Event):void {
    addChild(myPreloader);
    myPreloader.x = stage.stageWidth/2;
    myPreloader.y = stage.stageHeight/2;
function showProgress(event:ProgressEvent):void {
    var percentLoaded:Number = event.bytesLoaded/event.bytesTotal;
    myPreloader.loading_txt.text = "Loading - " + Math.round(percentLoaded * 100) + "%";
    myPreloader.bar_mc.width = 198 * percentLoaded;
function showContent(event:Event):void {
    removeChild(myPreloader);
    addChild(myLoader);
On it's own, it works fine.
Then I added a MC with the instance name "skipIntro", and then added this script to the script above:
skipIntro.addEventListener(MouseEvent.CLICK, fl_ClickToGoToWebPage_2);
function fl_ClickToGoToWebPage_2(event:MouseEvent):void
    navigateToURL(new URLRequest("/residences/residences.php"), "_blank");
Any help? Thanks.

There doesn't appear to be anything wrong with the code. Does it start behaving correctly again if you comment out that code? Do you get any error messages? The behavior you describe (looping/blinking) is indicative of an unhappy processor.

Please help me with an as3 preloader

Hi All,
I'm a flash noob and really need some help. I spent two full days trying to figure this out and I'm completely stuck.
I'm using a common preloader technique which basically uses one swf file (preloader.swf) to open another swf file (content.swf) using the following flash object:
var request:URLRequest = new URLRequest("content.swf");
It almost works but the progress never quite makes it to 100% but it suddenly stops around 85% and launches the video early. It screws up the timing and the video becomes out of synch with the audio.
Any help would be GREATLY apprecaited.
You can see what I mean here:
http://redwoodsmedia.com/help/preloader.html
Also the source files are included in this thread.
Thanks in advance.
Paxton

If you include the code that is in that file you may get more help as some people cannot and others will not open files that people attach.
For the moment I'll suggest taking a look at the tutorial linked below to see if it is different than what you've done...

Flash CS5 AS3 Preloader Issues

Hi.
I'm a complete novice with Flash and at risk at looking like 'Dumbest Poster of the Year', I'm requesting help/advic over a couple of issues.
My first concern is with a very simple preloader I've made for a movie. Here is the code (posted in first frame of movie; nothing else is in the frame except for the preloader itself):
import flash.events.Event;
stop();
addEventListener(Event.ENTER_FRAME, loaderF);
function loaderF(e:Event):void{
var toLoad:Number = loaderInfo.bytesTotal;
var loaded:Number = loaderInfo.bytesLoaded;
var total:Number = loaded/toLoad;
if(loaded == toLoad) {
removeEventListener(Event.ENTER_FRAME, loaderF);
gotoAndPlay(2);
} else {
PreLoader.PreLoaderFill.scaleX = total;
PreLoader.PercentLoaded.text = Math.floor(total*100) + "%";
When I simulate a download, the preloader works fine in all the settings except for 'T1'. On this setting, the movie loads to about 20% then the preloader stops, the movie begins and I receive the following error message in the output panel:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at FlashFront1_fla::MainTimeline/loaderF() .
The movie itself plays fine on all settings, including 'T1'. Debug doesn't report any issues on preloader or movie.
Can anybody give me any idea what the source of the issue is? Should I even be concerned about it givne that the movie plays without a problem?
My second question relates to the 'Simulate Download' pre-settings in Flash. I know their are people out there still on 56K dial-up, or with 'broadband' running at 500 KBS (in the UK at least), but nevertheless, the download simulation settings seem like they are all geared to internet as it was in 1997 and are hardly reflective of the capacity of modern connections. Why is this?
My movie is not large (about 320KB). Should I even be bothering with a preloader or am I wasting my time for a small minority audience (much like the web designers who still produce sites for the 12 people in the world still browsing in 800 x 600 res)?
Thanks for any help/advice.

Flash movies stream down and finish "loading" when the first frame and content that loads on the first frame is available, though frame 1001 might not be downloaded yet. You would think you'd be kinda safe with frame 2 on a T1, but I think the issue is things aren't updating in the right order rather than things not really being downloaded. Heck, it could even just be the T1 simulation that's causing problems.
Debug Movie probably isn't showing issues because it slows the timing enough to make everything ok. You could try trace statements too to see how far the code gets.
Also, you might try a full scale AS3 loader like this one http://www.republicofcode.com/tutorials/flash/as3loader/
I've found the Event.COMPLETE listener for the loader like this:
my_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading);
to be pretty accurate so far in regards to content truly being loaded where as previous methods gave false positives for loading.

Preloader help please

I have a small SWF file (number countdown eg. 10,9,8,7.6....)
that I want use as a preloader for my main SWF file.
Can someone please point me to an actionscript template that
I can use to implement this.
Thanks kindly for any help.

AS3 preloader - code overload

Is there an easier way to create a custom preloader animation
in AS3? The
only information I can find on the web tends to have about
two pages of code
with stuff like "packages" and "public/private functions"
which I've never
used and unfortunately do not understand. The idea seems
simple to me [(var
ratio = (bytesLoaded/bytesTotal)*100) then have a movie clip
(load_mc) one
hundred frames long displaying 00-99 respectively for each
frame. Then find
some way to call a function that says
[load_mc.gotoAndStop(ratio);]. I've
seen AS2 tutorials on this subject and they all kinda follow
this general
idea. Why then in AS3 do you need two pages of code for an
action that
required 5 or 6 lines of code in a previous version of
ActionScript (AS2)?
No..no...sorry that's not my question. **sighs** I just need
to know if
there is an easier-to-understand method to creating
prealoaders in AS3? I'm
making an intro movie for a new website and the final swiff
will probably be
close to 1 MB so I want to display a simple loading animation
instead of a
blank screen. Any help is greatly appreciated.

Yes, AS3 can look very complex, and many times it is. You
don't need to create packages to use AS3. You can, but you don't
have to. Writing classes in packages allow you to create libraries
of reusable code. You can just write code that will work for you in
a frame script space in a layer of your movie. In many cases, and
for simple movies, this works just fine.
To create a preloader animation, you can use the UILoader and
ProgressBar classes. You can also use the Loader class. Here's an
example that uses the Loader class:

Preload help

Hi there,
I will first admit that I use director mostly for moving
sprites and playing sounds, but when it comes to the script, I
suck. I am good at other types of scripting, and I have the general
idea of how to get the formula of a script to fuction, but I can
never get it going 100%. I am in desperate need of a preload
script, I know It's a hassle to see these n00b requests all the
time, but if someone could look at my script and tell me where I am
going wrong, it would be a big help. I only need this script to
work then I can apply it to all my work. Thanks in advance! :)
Movie has 1900 frames.
Here is my script, in frame 1:
on exitFrame
preLoad 0, 1900
if preLoad(0, 1900) = true then
go to "a"
end if
end
It accepts the script, but when it runs it comes back with:
Script Error: Function not defined
if preLoad(0, 1900) = true then
All i want to do is have this preload set up in frame 1, to
load the total frames, then advance to frame 2 (with the marker "a"
is) where a "play" button is on the stage.
Regards,
TMK.

That isn't usually necessary as Director is usually good at
loading assets
as needed, and it isn't usually desirable to potentially fill
up the RAM on
the user's computer - indeed, unloading members when they're
finished with
can be very helpful.
If you're doing a Shockwave movie, google for "lingo
preloader". In
particular, the articles at lingoworkshop.com are useful.
Then in the google
results page click on "Groups" up near the top and have a
browser through

Cs4 as3 preloader

Hi,
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();
function done(e:Event):void
removeChildAt(0);
percent = null;
addChild(l);
and here is the link to the file:
http://www.raidcanada.com/preloader-org-test.html
2- used the code suggested, which does the preloading directly in the main swf file:
stop();
//Import the required assets
import flash.display.*;
//Stop the playhead while loading occurs
this.stop();
//Create a listener to call the loading function as the movie loads
this.loaderInfo.addEventListener (ProgressEvent.PROGRESS, PL_LOADING);
/*This is the main function, basically it grabs the total and loaded bytes,
calculates a percentage, and displays it by stretching the bar and adjusting
the textfield display. If your bar/textbox instancenames are NOT lbar/lpc,
you'll need to adjust this code to match your instance names*/
function PL_LOADING(event:ProgressEvent):void {
var pcent:Number=event.bytesLoaded/event.bytesTotal*100;
//Stretch the bar
lbar.scaleX=pcent/100;
//Display the % loaded in textfield
lpc.text=int(pcent)+"%";
//If the movie is fully loaded, kick to the next frame on the main timeline
//You may wish to change the gotoAndStop(2) to a gotoAndPlay(2)
if(pcent==100){
this.gotoAndPlay(2);
This one doesn't work either, and if you refresh the page, you get only the bar, instead of refreshing the main swf.
http://www.raidcanada.com/test/test-2.html
3- use the code suggested to replace the preceding version:
stop();
addEventListener(Event.ENTER_FRAME,checkLoad);
function checkLoad(e:Event):void {
var pcent:Number=this.loaderInfo.bytesLoaded /this.loaderInfo.bytesTotal*100;
lbar.scaleX=pcent/100;
lpc.text=int(pcent)+"%";
if (pcent==100) {
removeEventListener(Event.ENTER_FRAME,checkLoad);
this.gotoAndPlay(2);
This one loads correctly (without the percentage or progress bar) and the refresh is OK.
http://www.raidcanada.com/test/test-1.html
The idea is to have this page load correctly showing a percentage sign and a progress bar until the loading is complete for this page:
http://www.raidcanada.com/entete-multi-hiver-1-test.html
Every time I test the swf directly in Flash CS4 with the simulated download, I get the progress bar and percentage correctly.
I also tried with Firefox and get the same results.
FLAs are at:
http://www.raidcanada.com/test/test-1.fla
http://www.raidcanada.com/test/test-2.fla
and screenshots of FLASH (showing the progress bar in "test movie" with simulated download):
http://www.raidcanada.com/test/screenshot-test-1.jpg
http://www.raidcanada.com/test/screenshot-test-2.jpg
Am I missing something?
THank you in advance

Hi,
I am using Internet Explorer 8, version 8.0.7600.16385 with Windows 7 Ultimate or Firefox 3 version 3.5.9
If I flush the cache and load the page:
http://www.raidcanada.com/entete-multi-hiver-1-test.html
It takes about 5 seconds with a blank screen before I get the main swf displayed.
If I load the page: http://www.raidcanada.com/test/test-1.html
It takes about 1 second with a blank screen before I get the main swf displayed. The main swf file is much smaller.
I also did a lot of tests, and still the same problem. Temporarely, on the production site, I ended up installing a static Image saying "Loading", without the code, which then loads the large swf. But some customers are seeing the "Loading" for 14 sec to 24 seconds, depending of the swf file.
I know the code suggested is probably working with CS3 and AS2, but I need to make it work with CS4 and AS3, because my other code is all in AS3, built with CS4. As I said before, if I make a simulation, the simulation is perfect.
Thanks

Preloader help

can someone please help me out setting up my preloader... ive
got my main scene and scene 2 which is for my preloader... im just
looking to use one of the preloader components-- i dont want to
make one.... ive created a layer in scene 2 and placed the
preloader there---now how do i script it to go from scene 2 to my
movie...ive ooked at the tutorial's and it still confuses me...
again ive got scene 2 for my preloader and scene 1 which is my main
movie...
im looking to use not only a progress bar component... but
possibly a byte's loaded as well if that is possible...if that's to
much of an issue then ill just use the progress bar component..
ive got multiple progress bar components:
the byte's preloader set
a customizable load bar component
fr16 preload component
the flash ui components set
and the loader component from kirupa.com
im just looking to place the script...if you've got a sample
file please let me know; so, i can download and take it apart to
understand how it work's...
trey
if by chance you do a sample file-- either post it here or
email me @ [email protected]
thanks for your help...

Thanks for the assistance. I managed to get it figured out.
Corrected the target paths (listed below):
stop();
_root.holder_mc.loadingBar._xscale = 1;
var loadingCall:Number = setInterval(preloadSite, 50);
function preloadSite():Void {
var siteLoaded:Number = _root.holder_mc.getBytesLoaded();
var siteTotal:Number = _root.holder_mc.getBytesTotal();
var percentage:Number = Math.round(siteLoaded/siteTotal*100);
_root.holder_mc.loadingBar._xscale = percentage;
_root.holder_mc.percentClip.percentDisplay.text = percentage
+ "%";
trace("Percentage is Working");
_root.holder_mc.percentClip._x =
_root.holder_mc.loadingBar._x + _root.holder_mc.loadingBar._width;
_root.holder_mc.bytesDisplay.text = "loaded " + siteLoaded +
" of " + siteTotal + " bytes";
trace("Site Loaded is Working");
if (siteLoaded >= siteTotal) {
clearInterval(loadingCall);
gotoAndStop(5);
Text field was visible, font just needed to be embedded. As a
note I placed a dynamic text box that spec'd _sans as the font with
the 'use device fonts' option picked. I had to respec a different
font and embed it into the swf.
Thanks again for the assistance!

AS3 PreLoader Troubles

I have been trying to make my simple animated preloader work and am just about ready to throw in the towell.
import flash.events.ProgressEvent;
import flash.events.Event;
import flash.net.URLRequest;
myLoader.addEventListener(Event.COMPLETE, onComplete);
myLoader.addEventListener(ProgressEvent.PROGRESS , onProgress);

    var pct:Number = e.bytesLoaded / e.bytesTotal;
function onComplete(e:Event):void
    preloader_mc.X = -1000;
myLoader.load(new URLRequest("D.swf"));
PLEASE HELP!!!!!

use:

import flash.net.URLRequest;
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS , onProgress);

AS3 Preloader matching stage.stageWidth (simple)

Hello,
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;
var loaded:Number = this.stage.loaderInfo.bytesLoaded;
loadBar.scaleX = loaded/total;
loaderText.text = Math.floor((loaded/total)*100)+ "%"; (if percentage text is wanted)
if (total == loaded) {
gotoAndPlay(3);
this.removeEventListener(Event.ENTER_FRAME, loading);
This works perfectly well, but isn't that pleasing aesthetically.
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?
If anybody knows how this is achieved, through actionscript, in the timeline, I'd really appreciate the support
Thanks a lot!

I haven't been able to make this work straight away with this code:
var lbW:Number
var stageW:Number
var ratioNum:Number
resizeF(null);
stage.addEventListener(Event.RESIZE,resizeF);
function resizeF(e:Event){
lbW = loadBar.width
stageW = stage.stageWidth
ratioNum = stageW/lbW;
this.addEventListener(Event.ENTER_FRAME, loading);
function loading(e:Event):void {
var total:Number = this.stage.loaderInfo.bytesTotal;
var loaded:Number = this.stage.loaderInfo.bytesLoaded;
loadBar.scaleX = ratioNum*loaded/total;
if (total == loaded) {
gotoAndPlay(2);
this.removeEventListener(Event.ENTER_FRAME, loading);
But I shall explore and try and fix it.
Thanks so much for your time and expertise!
Really do appreciate it!

CS5, AS3 - Preloader

I've been searching for guides/tutorials, basically any sort of help in making a preloader for a game. Also looked through previous posts on this forum.
Whenever I have a preloader made without any errors and I click test movie (ctrl-enter), it skips the preloader and goes straight to my game's menuscreen. Fair enough, so I click simulate download, the window turns white, after that it turns grey with 3 or 4 dots blinking, as if it were a preloader, except not mine, after a while it goes into my games menuscreen again, completely bypassing the preloader.
A walkthrough for a simple preloader (just a percentage going from 0 to 100), some code I can copy-paste, anything to make it work, I've tried all I can think of.
/beg for help.

that code's in frame 1 of your main timeline, correct? if yes, copy the trace output using the following and paste it here:
stop();
trace(this.currentFrame,this);
import flash.events.ProgressEvent;
import flash.events.Event;
this.loaderInfo.addEventListener(ProgressEvent.PROGRESS, onLoading);
this.loaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onLoading(evt:ProgressEvent):void {
    var loaded:Number = evt.bytesLoaded / evt.bytesTotal;
    loadbarText.text = "LOADING: " + (loaded*100).toFixed(0) + "%";
trace(loadbarText.text);
function onComplete(event:Event):void {
    this.loaderInfo.removeEventListener(ProgressEvent.PROGRESS, onLoading);
    this.loaderInfo.removeEventListener(Event.COMPLETE, onComplete);
    loadbarText.visible = false;
    gotoAndPlay(2);
