Yes. While loading a SWF using wmode=transparent, loaderInfo doesn't fire
ProgressEvent.PROGRESS and Event.COMPLETE events for itself inside FireFox.
The solution is using a separate ENTER_FRAME event to check on the loading
state. You can read the bytesLoaded and bytesTotal (they're correctly
updated), it's just the events that never fire.
This is more or less what I use with a hack event, on top of my normal
events:
protected function startSelfLoading(): void {
addEventListener(Event.ENTER_FRAME, onSWFLoadingProgressHack,
false, 0, true); // This is needed because Flash won't fire SWF loading
events if wmode=transparent!
root.loaderInfo.addEventListener(ProgressEvent.PROGRESS,
onSWFLoadingProgress, false, 0, true);
root.loaderInfo.addEventListener(Event.COMPLETE,
onSWFLoadingComplete, false, 0, true);
}
protected function onSWFLoadingProgress(e:ProgressEvent): void {
swfLoadingPhase = e.bytesLoaded / e.bytesTotal;
}
protected function onSWFLoadingProgressHack(e:Event): void {
// This is needed because Flash won't fire SWF loading events if
wmode=transparent!
swfLoadingPhase = root.loaderInfo.bytesLoaded /
root.loaderInfo.bytesTotal;
if (swfLoadingPhase >= 1) {
// Just for safety's sake, wait a few frames after it has
finished loading
framesAfterLoaded++;
if (framesAfterLoaded > 5) onSWFLoadingComplete(null);
}
}
protected function onSWFLoadingComplete(e:Event): void {
swfLoadingPhase = 1;
removeEventListener(Event.ENTER_FRAME,
onSWFLoadingProgressHack);
root.loaderInfo.removeEventListener(ProgressEvent.PROGRESS,
onSWFLoadingProgress);
root.loaderInfo.removeEventListener(Event.COMPLETE,
onSWFLoadingComplete);
// Show website, etc
}
Loading secondary SWFs seem to work normally. It's just want the firts SWF
is loading itself.
Zeh
