[ODE] Holding bodies like in HL2

[Christoph Beyer]

I looked at your code and i thin the bug is this:

you wrote

> I don't do any collision detection with ray

but in void Core::NearCallback (dGeomID o1, dGeomID o2)
is only checked if o1 is a ray, but if o2 is the ray,
then the ray is always colliding with the capsule of the player.

try this:

if (dGeomGetClass (o1) == dRayClass ||dGeomGetClass (o2) == dRayClass)
{
    return;
}



cheers
