Member Enumeration Documentation

anonymous enum

Enumerator
Unknown	Contact state was not (can not) be determined (if state == Unknown all other fields are not used)
Separated	Bodies are far away.
Separating	Bodies are contacted but moving apart.
Contacted	Bodies are contacted but resting.
Colliding	Bodies are collising.
Intersected	Bodies are interpenetrating.
