problem with avatar climp a ramp

[befl0]

Hi,

It's difficult to put a code because it's working with a VRPN.

I hope I will be more explicit. I controlled a wheelchair to do a race. In this race the wheelchair have to climb the ramp I had in this topic. But the viewpoint is controlled by the glasses so the viz.collision(viz.ON) is not working. So I don't know how to climb the ramp to the wheelchair.

I hope I was more clear.

Thanks
