programming flash
1

HI, I have editied a an xml gallery from Kirupa turoials, here is the link (http://www.kirupa.com/developer/mx2004/xml_flash_photogallery.htm)

I have removed the buttons and used a set interval instead so the pictures change by themselves, Issue I have is, the movie wont loop when it gets to the last picture. Can anyone help, code is below…thank you

function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
description = [];
description2 = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
description2* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
}
firstImage();

} else {
    content = "file not loaded!";
}

}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load(“images.xml”);

updateAfterEvent();
setInterval(nextImage,8000);

p = 0;
this.onEnterFrame = function() {
filesize = picture.getBytesTotal();
loaded = picture.getBytesLoaded();
preloader._visible = false;
if (loaded != filesize) {
preloader.preload_bar._xscale = 100*loaded/filesize;
} else {
preloader._visible = false;
if (picture._alpha<100) {
picture._alpha += 3;
}
}
};

function nextImage() {
if (p<(total-1)) {
p++;

    if (loaded == filesize) {
        picture._alpha = 0;
        picture.loadMovie(image[p], 1);
        desc_txt.text = description[p];
        desc_txt2.text = description2[p];
    }
}

}

function prevImage() {
if (i==(total)) {
firstImage();
picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
}
}

function firstImage() {

if (loaded == filesize) {
    picture._alpha = 0;
    picture.loadMovie(image[0], 1);
    desc_txt.text = description[0];
    desc_txt2.text = description2[0];
}

}
