Here's my newbie problem.
Let's suppose a sphere rolling on a plane.
If I use this contact parameters:
contact[i].surface.mode =3D dContactBounce;
contact[i].surface.mu =3D dInfinity;
contact[i].surface.mu2 =3D 0;
contact[i].surface.bounce =3D 0.5;
contact[i].surface.bounce_vel =3D 0.1;
My sphere fall on the floor and roll again and again and never stop.
Does this mean that I must use a friction contact between the sphere and =
the floor ?
How could I do to set the good parameters for it ?
Or I must use air friction resistance ? How could I make this ?
Thanks for answering me...
Charles.
