Ability to scrub time back and forth

[xeolabs]

Would be nice to support time moving backwards, useful for when controlling tweens with a time slider (scrubber) widget.

At the moment tween.js only seems to support time moving forwards..perhaps with the way it manages chaining etc. this is not practical?

Hmmm, I wonder if we could do this in a simple way, like doing TWEEN.update( time ); or something like that...

Yes, I was thinking exactly on those terms. Make everything a function of time --either time we keep track of (as we do right now), or by manually updating the time as mrdoob suggested.

Probably chaining might be a tad broken when moving backwards :-)

I very much agree that this would be a really useful feature. In fact, I will need something like this if I am to use tween for my current project.

I think sequencer.js fits better this task.
