Cloth dynamics (friction)


Im doing some R&D on how to animate a reptilian tongue realistically.

Ive found a couple of videos here:

This got me thinking of using the cloth modifier to simulate the tongue, using a bone to propell the cloth forward.

So I put a bone inside the tongue mesh, put a cloth modifier on that mesh and added the bone as a collision object.
I animated the bone shooting out and quickly retracting and then I started fiddling around with the cloth settings.

I got some nice stretching and secondary motion out of this, but I couldnt get the cloth to propell forward, as the bone was retracting, the cloth just got pulled back with it.

Any idea how I could achieve what Im trying to create?

I know I probably could just use a bone chain, skin the tongue mesh to it and hand key it, but Id still like to know if it could work...

Probably got something to do with the restriction of the cloth modifier, as it doesnt actually have any velocity (pivot stays in the same place as it moves around), I remember something about that from that EUE Class on blowing things up from Louis Marceaux...
