Random Slideshow

programming flash
1

I’ve gone through the forum over and over again to find a solution to my problem… and I’ve come up unlucky. Unless I’ve overlooked something, in which case I still need help.

I used the tutorial for Photo Gallery Using XML and Flash on the site. I originally used the code for the slideshow, but the need for back, forward, and pause buttons was called for. Then, I needed the slideshow to load the first image randomly from the XML file, which it does. However, I’d like to code it so that it continues in a non-random order from the current picture it is on. Say, if it randomly loads the 8th image in a set of 20, I want the slideshow to continue to image 9 in the xml file, so on and so forth. Is this possible?

Here is my actionscript:


function loadXML(loaded) {
	if (loaded) {
		xmlNode = this.firstChild;
		image = [];
		total = xmlNode.childNodes.length;
		for (i=0; i<total; i++) {
			image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
		}
		randomImage();
	} else {
		content = "file not loaded!";
	}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
controls.play_btn._visible = 0;
p = 0;
delay = 7000;
controls.pause_btn.onRelease = function() {
	clearInterval(myInterval);
	controls.pause_btn._visible = 0;
	controls.play_btn._visible = 100;
};
controls.play_btn.onRelease = function() {
	myInterval = setInterval(pause_slideshow, delay);
	controls.pause_btn._visible = 100;
	controls.play_btn._visible = 0;
};
controls.previous_btn.onRelease = function() {
	if (p == 0) {
		p = total;
		lastImage();
	}else{
		prevImage();
	}
	if (p == (total-1)) {
		prevImage();
	}
};
controls.next_btn.onRelease = function() {
	//nextImage();
	if (p == (total-1)) {
		p = 0;
		firstImage();
	} else {
		nextImage();
	}
};
this.onEnterFrame = function() {
	filesize = picture.getBytesTotal();
	loaded = picture.getBytesLoaded();
	preloader._visible = true;
	if (loaded != filesize) {
		preloader.preload_bar._xscale = 100*loaded/filesize;
	} else {
		preloader._visible = false;
		if (picture._alpha<100) {
			picture._alpha += 10;
		}
	}
};
function nextImage() {
	controls.pause_btn._visible = 100;
	controls.play_btn._visible = 0;
	if (p<(total-1)) {
		p++;
		if (loaded == filesize) {
			clearInterval(myInterval);
			picture._alpha = 0;
			picture.loadMovie(image[p], 1);
			slideshow();
		}
	}
}
function prevImage() {
	controls.pause_btn._visible = 100;
	controls.play_btn._visible = 0;
	if (p>0) {
		p--;
		clearInterval(myInterval);
		picture._alpha = 0;
		picture.loadMovie(image[p], 1);
	}
}
function firstImage() {
	if (loaded == filesize) {
		picture._alpha = 0;
		picture.loadMovie(image[0], 1);
		slideshow();
	}
}
function lastImage() {
	if (loaded == filesize) {
		picture._alpha = 0;
		picture.loadMovie(image[total-1], 1);
		slideshow();
	}
}
function randomImage() {
	if (loaded == filesize) {
		picture._alpha = 0;
		picture.loadMovie(image[random(total)], 1);
	}
	slideshow();
}

function slideshow() {
	myInterval = setInterval(pause_slideshow, delay);
}
function pause_slideshow() {
	clearInterval(myInterval);
	if (p == (total-1)) {
		p = 0;
		firstImage();
	} else {
