Photogallery image loadbar help??

[cowman345]

Creating a photogallery. I'm loading the full-sized photos into a movieclip on my main timeline with the following bit of code:

this.loader_mc.loadMovie(whatToLoad, "loadSpot_mc");

I have a loadbar image set up on another layer of my main timeline with the following actionscript (note: i checked to make sure all objects are properly defined, etc.):

frame 1:

bytes_loaded = Math.round(this._parent.loader_mc.getBytesLoaded() );
bytes_total = Math.round(this._parent.loader_mc.getBytesTotal()) ;
getPercent = bytes_loaded/bytes_total;
this.loadbarBar_mc._width = getPercent*100;
this.loadText = Math.round(getPercent*100)+"%";
if (bytes_loaded == bytes_total) {
this.gotoAndPlay(3);
}

frame 2:

gotoAndPlay(1);

frame 3: blank

-----

So the problem is the loadbar isn't moving... it's hanging around looking 50% loaded, and the loadText says 100% even while images are loading. I'm not too experienced at loading movies dynamically, so i'm sure i'm doing something wrong. Any help would be greatly appreciated!

Loading jpgs, irritatingly, doesnt work the same as loading swfs.

You need to look at its width to determine whether its loaded (if the width is 0 then the pic hasnt been imported yet)

try this.


MovieClip.prototype.loadPic = function(pic) {
yourPhotoContainerMc.loadMovie(pic);
_root.onEnterFrame = function() {
var t = yourPhotoContainerMc.getBytesTotal(), l = yourPhotoContainerMc.getBytesLoaded();
percentThatsLoaded = Math.round((l/t)*100);
yourLoadingBar._visible = 1;
if (l == t && yourPhotoContainerMc._width>0 && yourPhotoContainerMc._height>0) {
var w = yourPhotoContainerMc._width, h = yourPhotoContainerMc._height;
yourLoadingBar._visible = 0;
delete this.onEnterFrame;
} else {
yourLoadingBar._width = percentThatsLoaded;
loadingProgressTextField.txt.text = percentThatsLoaded+" % loaded";
}
};
};
yourPhotoContainerMc.loadPic("yourPic.jpg");


It will resize the bar from 1 pixel to 100, depending on the percent loaded. You can use some simple maths if you want it to finish bigger or smaller than 100px, but make sure its a multiple or division of "percentThatsLoaded" as thats what gives it a changing size.
