preloading Problem

[ianhb]

hi all,
I have a problem with preloaders
My movie loads external SWF's. each swf has a preloader scene with this code

bytes_loaded = Math.round(getBytesLoaded());
bytes_total = Math.round(getBytesTotal());
getPercent = bytes_loaded/bytes_total;
this.loadBar._width = getPercent*200;
this.loadText = Math.round(getPercent*100)+"%";
if (bytes_loaded == bytes_total) {
	gotoAndPlay("Scene 1",1);
}

On my modem connection at home it works fine but at work the preloader doesnt appear. I get a blank screen untill the whole movie has loaded then it goes straight to Scene 1 frame 1.

Could our proxy server be causing problems?
Can anyone offer any help?

TIA

Ian

Hi,

Is the system/connection at work slower/faster than at home?
Is the size of the preloader small enough?

Sometime building in a pre-preloader helps if the preloader is a bit 'voluptuous'. Put it on the second frame, and start your main preloader at 3 (lable it "MainPreloader" or something). Leave the first frames empty.

if (_root.getBytesLoaded()==_root.getBytesTotal()) {
gotoAndPlay("Scene1", 1);
}
// N is the number of frames in your preloader.
if (_root._framesloaded > N) {
gotoAndPlay("MainPreloader");
}

thanks for the reply

work has an ISDN connection and home is a 56k modem.
i know my preloader works fine on all the systems i have tried it on apart from at work.

the size of the preloader should be tiny, its only a couple of words, a dynamic text box and a bar that changes length

you can check it out here -> www.orchardcdg.co.uk/home.htm

i seems that our server at work is holding onto the incoming files and then sending them to my terminal when it is downloaded instead of streaming it (?)

i have also had problems with other peoples preloaders not working so i was wondering if it is a known problem with proxy servers?

Well, honestly, I don't know. Could be. I'm no server wiz.

thanks for trying!

anyone else?

No probs! Happy Flashing!

Change this line

this.loadBar._width = getPercent*200;
to

this.loadBar._xscale = getPercent*100;

also give your frames names like "scene1Frame1"

[ianhb]

ok, i'll try it thanks.
the reason for

this.loadBar._width = getPercent*200;

is because the finisehed length of the movie clip is 200px.

I know the preloader works but its just not being displayed

You could have a generic preloader in your main movie, that preloads all of your other movies, without them having their own preloaders...

http://www.flashkit.com/board/showth...hreadid=456020

As for your preloading code, there first should be some reference to what you're loading, eiter _root, or more probably in your case, at least this...

bytes_loaded = Math.round(this.getBytesLoaded());
bytes_total = Math.round(this.getBytesTotal());
getPercent = bytes_loaded/bytes_total;

If your loadBar graphic is actually 200 pixels long, use _xscale instead of _width... And 100%...
this.loadBar._xscale = getPercent*100;

this.loadText = Math.round(getPercent*100)+"%";

You should use >= in your if statement, rather than ==...

if (bytes_loaded >= bytes_total) {
gotoAndPlay("Scene 1",1);
}

Now if you're using components, Export on the first frame stuff (attached movie clips or sound objects) and/or embedding fonts in your movies, then the preloader might not display correctly anyways, until all that has to be downloaded on the first frame has...

You would then need a workaround...
