SlideShow AS issue??

Question

OK I have this flash based slideshow that generally did what
I wanted but I then I needed to tweak it to add some nav elements
and a Button to launch a URL (see second AS code) - OK at first the
AS works Slideshow wise - if I use the folowing:
delay = 3000;
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
description = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image
= xmlNode.childNodes.childNodes[0].firstChild.nodeValue;
description
= xmlNode.childNodes.childNodes[1].firstChild.nodeValue;
firstImage();
} else {
content = "file not loaded!";
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
p = 0;
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() {
if (p<(total-1)) {
p++;
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
picture_num();
slideshow();
function prevImage() {
if (p>0) {
p--;
picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
picture_num();
function firstImage() {
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[0], 1);
desc_txt.text = description[0];
picture_num();
slideshow();
function picture_num() {
current_pos = p+1;
pos_txt.text = current_pos+" / "+total;
function slideshow() {
myInterval = setInterval(pause_slideshow, delay);
function pause_slideshow() {
clearInterval(myInterval);
if (p == (total-1)) {
p = 0;
firstImage();
} else {
nextImage();
But then when I put other code into the AS with help from
another developer - my slideshow stops functioning (Automatically,
the slide show has to be manually navigated to get to the next
slide instead of it after a delay going to the next slide - the
code I have that does that is:
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
header = [];
caption = [];
url = [];
delay = [];
slideNumber = [];
slideTotal = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image
= xmlNode.childNodes.childNodes[0].firstChild.nodeValue;
header
= xmlNode.childNodes.childNodes[1].firstChild.nodeValue;
caption
= xmlNode.childNodes.childNodes[2].firstChild.nodeValue;
url
= xmlNode.childNodes.childNodes[3].firstChild.nodeValue;
delay
= xmlNode.childNodes.childNodes[4].firstChild.nodeValue;
slideNumber
= xmlNode.childNodes.childNodes[5].firstChild.nodeValue;
slideTotal
= xmlNode.childNodes.childNodes.length;
trace(slideTotal);
firstImage();
} else {
content = "file not loaded!";
my_Date = new Date();
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
listen = new Object();
Key.addListener(listen);
previous_btn.onRelease = function() {
clearInterval(myInterval);
prevImage();
next_btn.onRelease = function() {
clearInterval(myInterval);
nextImage();
play_btn._visible = 0;
p = 0;
pause_btn.onRelease = function() {
clearInterval(myInterval);
pause_btn._visible = 0;
play_btn._visible = 100;
play_btn.onRelease = function() {
myInterval = setInterval(pause_slideshow, delay[p]);
pause_btn._visible = 100;
play_btn._visible = 0;
p = 0;
this.onEnterFrame = function() {
filesize = picture.getBytesTotal();
loaded = picture.getBytesLoaded();
if (loaded != filesize) {
preloader.preload_bar._xscale = 100*loaded/filesize;
} else {
preloader._visible = false;
if (picture._alpha<100) {
picture._alpha += 5;
function nextImage() {
pause_btn._visible = 100;
play_btn._visible = 0;
previous_btn._visible = 100;
next_btn._visible = 100;
if (p<(total-1)) {
p++;
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[p], 1);
head_txt.text = header[p];
capt_txt.text = caption[p];
num_txt.text = slideNumber[p];
url_btn = url[p];
go_btn = url[p];
picture_num();
slideshow();
}else{
p = 0;
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[p], 1);
head_txt.text = header[p];
capt_txt.text = caption[p];
num_txt.text = number[p];
url_btn = url[p];
go_btn = url[p];
picture_num();
slideshow();
function prevImage() {
pause_btn._visible = 100;
play_btn._visible = 0;
if (p>0) {
p--;
picture._alpha = 0;
picture.loadMovie(image[p], 1);
head_txt.text = header[p];
capt_txt.text = caption[p];
num_txt.text = slideNumber[p];
url_btn = url[p];
go_btn = url[p];
picture_num();
}else{
p = total - 1;
picture._alpha = 0;
picture.loadMovie(image[p], 1);
head_txt.text = header[p];
capt_txt.text = caption[p];
picture_num();
function firstImage() {
previous_btn._visible = 0;
next_btn._visible = 100;
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[0], 1);
head_txt.text = header[0];
capt_txt.text = caption[0];
url_btn = url[0];
go_btn = url[0];
picture_num();
slideshow();
function picture_num() {
current_pos = slideNumber[p];
pos_txt.text = current_pos +"/" +slideTotal;
function slideshow() {
myInterval = setInterval(pause_slideshow, delay[p]);
function pause_slideshow() {
clearInterval(myInterval);
if (p == (total-1)) {
p = 0;
firstImage();
} else {
nextImage();
*** this is the AS for the button that lanches the URL:
on (release) {
getURL(url_btn, "_self");
In any case can anyone help me figure out what I messed up so
I can get this running again?
if you go to :
http://www.ruf.rice.edu/~jestrada/CSS/slideshow.zip
you can download all o fthe files needed to view the page with the
flash including the XML and photos...

Answer 1

In the following function p is undefined because you didn't
provide p as a parameter to the function. As a result delay[p] is
undefined.
function slideshow() {
myInterval = setInterval(pause_slideshow, delay[p]);
trace(delay[p]);//will return undefined
If you hardcode the delay, the slideshow autoplays
function slideshow() {
myInterval = setInterval(pause_slideshow, 3000);
}
