Hi,
i’ve got an xml gallery and just don’t figure out how to remove the already loaded pictures before loading a new set, when i load a new set it place over the previously loaded images…
i know i must call 2 functions, first to unload content, second to load new :
//following 2 functions will be called by a button :
// removes previously placed objects
function clearLoadedPictures():void {
//code i want.....
//
function LoadNewPictures();
}
// Load another ,xml to load new pictures set - this function works fine
function LoadNewPictures():void {
//
i_g = 0;
//
// xml data
var xml_gallery:XML = new XML();
var xml_gallery_List:XMLList = new XMLList;
// XML data loader...
var xmlUrlReq:URLRequest = new URLRequest("xml/gallery2.xml");// gallery2.xml will replace gallery.xml already loaded
var xml_gallery_UrlLoader:URLLoader = new URLLoader(xmlUrlReq);
//
xml_gallery_UrlLoader.addEventListener(Event.COMPLETE, xml_gallery_Complete);
xml_gallery_UrlLoader.addEventListener(IOErrorEvent.IO_ERROR, xml_gallery_LoadFailed);
}
and here the original gallery code :
var _mc:item;
var total:int;
var i_g:int;
var id:int;
//
var btn_Gallery_Ready:Boolean;
//
var speedX:Number;
var spaceR:Number;
var img_gallery_Loader:Loader;
//
i_g = 0;
//
// xml data
var xml_gallery:XML = new XML();
var xml_gallery_List:XMLList = new XMLList;
// XML data loader...
var xmlUrlReq:URLRequest = new URLRequest("xml/gallery.xml");
var xml_gallery_UrlLoader:URLLoader = new URLLoader(xmlUrlReq);
//
xml_gallery_UrlLoader.addEventListener(Event.COMPLETE, xml_gallery_Complete);
xml_gallery_UrlLoader.addEventListener(IOErrorEvent.IO_ERROR, xml_gallery_LoadFailed);
//
bottom24.gallery.content_mc.addEventListener(MouseEvent.ROLL_OVER, startScroll);
bottom24.gallery.content_mc.addEventListener(MouseEvent.ROLL_OUT, stopScroll); //
// xmlComplete function
function xml_gallery_Complete(e:Event):void
{
xml_gallery = XML(e.target.data); //
xml_gallery_List = xml_gallery.item; // <item> in gallery.xml
total = xml_gallery_List.length();
spaceR = xml_gallery.attribute("space"); // specified in gallery.xml file as is : <gallery space="119" speed="0.2">
speedX = xml_gallery.attribute("speed");
//
init_gallery();
}//;
