I’m working off the XML photo gallery tute found here: xml_flash_photogallery.htm[U]
[/U]My wish is to have the array loop forward and backwards, so by clicking next you will eventually get back to the first value, and if you keep clicking previous you will eventually see the last value in the array.
I found some Scotty code (first line in the nextImage function) that enabled this function with the next button, but I can’t figure out how to use it for the previous button. Can anyone help?
Here’s the code:
[AS]
previous_btn.onRelease = function() {
prevImage();
};
next_btn.onRelease = function() {
nextImage();
};
/////////////////////////////////////
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() {
//next line will let it start over again
p<(total-1) ? p++ : p=0;
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
picture_num();
}
}
}
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();
}
}
[/AS]
