Hello,
I really need your guys’ help on this one. I have this XML based slide show for Flash that works fairly well (based on the XML slideshow tutorial on the site). The slide show currently preloads the images between the slides. It works pretty well on a broadband connection since the load time doesn’t seem to get in the way of viewing the pictures. However, it gets pretty annoying to see the loading screen between each image. I was wondering can I tell flash to preload all the images on the first slide before starting the slide show? An example of the code in action is at [URL=“http://andygoldman.com/busanutenterprises_css/spaceprogram/slideshow.html”]http://andygoldman.com/busanutenterprises_css/spaceprogram/slideshow.html .
Here is the actionscript that currently drives the slide show:
(“picture” is the name of the movie clip that the images load into)
[COLOR=Gray]function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
name = [];
dimensions = [];
addinfo = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firs[/COLOR][COLOR=Gray]tChild.nod[/COLOR][COLOR=Gray]eValue;
name* = xmlNode.childNodes*.childNodes[1].firs[/COLOR][COLOR=Gray]tChild.nod[/COLOR][COLOR=Gray]eValue;
dimensions* = xmlNode.childNodes*.childNodes[2].firs[/COLOR][COLOR=Gray]tChild.nod[/COLOR][COLOR=Gray]eValue;
addinfo* = xmlNode.childNodes*.childNodes[3].firs[/COLOR][COLOR=Gray]tChild.nod[/COLOR][COLOR=Gray]eValue;
}
firstImage();
} else {
content = “file not loaded!”;
}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load(“images.xml”);
