Control collision of this object list with other objects.

Group:
Defines Collision Group of this object list.
(The objects which in the AqBullet object are always “1”)

Collide with:
Defines collide group with this object list. Only enabled group get collide with these object. This setting is working on bidirectional. If object list A and B set collision group “2”. And object list A enabled collide with “2”, but object list B disabled collide with “2”, each object group don’t collide with each other. And also all objects in the object list B don’t get collide with each other.
(The objects which in the AqBullet object are always enabled all group)
