Hi, Thanx for the tut. I am working on this with a project of mine but it doesn’t work.
First I import the class:
import com.fjakobs.utils.*
Then I create the timer:
var newTimer:Number = 5000;
var slideTimer:ExtendedTimer = new ExtendedTimer(newTimer);
function onSlideFadeIn():void {
// check, if the slideshow is currently playing
// if so, start the timer again
if (bolPlaying && ! slideTimer.running) {
slideTimer.start();
}
}

I am using this class with this code showed on this website:
http://www.thetechlabs.com/tutorials/xml/extending-the-as3flash9-slideshow-with-xml/

I hope someone can help me with this,
thanx

It seems the error comes into play when the timer count gets reset.
Try running a timer with an interval of 50ms and pause it every other second while looking at yr trace window.

If anyone has an opinion about this error feel free to share, i have no idea why this is occurring.
Kudos for the class! Gets the job done and is very usefull with minimal fancyness

hi there

I’m using Kipp’s compilation to the letter. Everything seems to be working fine but i get an error nonetheless.
Can anyone help?

RangeError: Error #2066: The Timer delay specified is out of range.

at flash.utils::Timer/set delay()
at com.fjakobs.utils::ExtendedTimer/pause()

Here is the version I compiled with all of the above changes. It seems to be working great! Hope this helps everyone. I know this has been a huge benefit to me!

does anyone have a stable, complete, working, tested, etc, version of this? I see a bunch of evolution going on, wondering if I could get a final version? thanks to all

I should also mention that if you implement my fix from above, then you should change line 46 to:
super.delay = delay – (new Date().time – _startTime);
…unless you also use DorkBot’s fix (recommended), then change his line delay = thisDelay; into super.delay = thisDelay;

Great little class. Just one thing I’d like to add which may be useful to others. I found that if I’d set the delay after the class was instantiated, then the specified delay would only work once, and afterwards it would revert to the original delay that was specified when the class was created. After adding the following, the problem was solved

override public function set delay(n:Number):void {
super.delay = n;
_initialDelay = n;
}
