Randomly cycling through XML gallery

1

Hi all,

I’ve got an interesting one for ya. How do I make a random XML auto gallery. The actionscript is for my auto gallery, which loads and changes every 15 seconds. How do I make it so that it loads from the XML file randomly?!

Any help would be much appreciated! Thanks guys and gals.

See code below…


// set up variable and constants 
var pathToPics = new String();
var pArray = new Array();
var tArray = new Array();
var fadeSpeed = 20;
var pIndex = 0;



// change photo prototype function
MovieClip.prototype.changePhoto = function(d) {
	this.pIndex = (this.pIndex+d)%this.pArray.length;
	if (this.pIndex<0) {
		this.pIndex += this.pArray.length;
	}
	this.onEnterFrame = fadeOut;
};



// fade pictures out prototype 
MovieClip.prototype.fadeOut = function() {
	if (this.photo._alpha>this.fadeSpeed) {
		this.photo._alpha -= this.fadeSpeed;
	} else {
		this.loadPhoto();
	}
};



// load photo prototype
MovieClip.prototype.loadPhoto = function() {
	var p = this.photo;
	p._alpha = 0;
	p.loadMovie(this.pathToPics+this.pArray[this.pIndex]);
	this.onEnterFrame = loadMeter;
};



// preloader function for pictures
MovieClip.prototype.loadMeter = function() {
	var l, t, per;
	l = this.photo.getBytesLoaded();
	t = this.photo.getBytesTotal();
	per = Math.round((l/t)*100);
	loadBar._visible = 1;
	if (t>0 && t == l) {
		this.onEnterFrame = fadeIn;
		loadBar._visible = 0;
	} else {
		loadBar._xscale = per;
	}
};



// fade in pictures prototype
MovieClip.prototype.fadeIn = function() {
	if (this.photo._alpha<100-this.fadeSpeed) {
		this.photo._alpha += this.fadeSpeed;
	} else {
		this.photo._alpha = 100;
		this.onEnterFrame = null;
	}
};



// set timing for the photo change
setInterval(this,"changePhoto", 15000, 1)



// set up XML
var gallery_xml = new XML();
gallery_xml.ignoreWhite = true;
gallery_xml.onLoad = function(success) {
	if (success) {
		var gallery = this.firstChild;
		pathToPics = gallery.attributes.path;
		for (var i = 0; i<gallery.childNodes.length; i++) {
			tArray.push(gallery.childNodes*.attributes.title);
			pArray.push(gallery.childNodes*.attributes.source);
		}
		loadPhoto();
	} else {
		title_txt.text = "Error!";
	}
};



// XML gallery file
gallery_xml.load("autogallery.xml");

In addition, is there a way to stop possible recurrsion? This would be excellent to stop the same image being called twice in a row…
