 | | | Speed of looping library items | Speed of looping library items 2004-05-26 - By John Grden
Back
When iterating through a library of sounds, if I access the name property of
the item object, it's fast. If I access a property of the soundItem (subclass
of the item class - IE: bitRate), it slows drastically.
Anyone experienced this? Have a suggestion for doing this more efficiently or
a workaround?
Basically, I need to list out all sounds, but when there's a library of, say,
50, I get an error about the script running slowly etc.
Run this against any FLA that has sounds in the library. Change the "bitRate"
var to "itemType" and you'll see a huge difference in speed.
var dom = fl.getDocumentDOM().library;
libe = dom.items;
fl.trace(libe.length);
for(x=0;x<libe.length;x++)
{
dom.selectItem(dom.items[x].name);
var selItems = fl.getDocumentDOM().library.getSelectedItems();
fl.trace(selItems[0].name + ", " + selItems[0].bitRate);
}
