constraint. When off, the constraint is single-bodied and the point occupied
by the Parent Space sub-object is the parent.
You assign the chassis by clicking this button and then selecting a rigid body
from any viewport. Thereafter the button displays the name of the chassis
object.
Child Displays the name of the second rigid body attached to the constraint.
You assign the child object by clicking this button and then selecting a rigid
body from any viewport.
Align Spaces To Use these options to align the bodies' local constraint spaces.
You can find out more about each option in
Working With Constraint Spaces
on page 3928.
Lock Relative Transform When on, the relative transform between the child
and parent constraint spaces is locked: If you move either space in the viewport,
the other space moves and rotates along with it, and vice-versa.
Strength group
Strength/Tau Govern the impulses applied to the constraint's bodies in order
to maintain the constraint, and so how strongly the constraint works to restrict
their movement. You can find out more about these parameters in
Strength
and Tau
on page 3944.
Suspension Parameters group
Min Limit The distance the constraint allows the wheel to move along the
suspension axis relative to the chassis, in the direction opposite that indicated
by the icon’s suspension arrow. For example, if Min Limit=–5, then the wheel
cannot move more than five units backwards along the suspension axis with
respect to the constraint’s spaces.
Max Limit The distance the constraint allows the wheel to move along the
suspension axis relative to the chassis, in the direction indicated by the icon’s
suspension arrow. For example, if Max Limit=10 then with respect to the
constraint’s spaces the wheel cannot move more than 10 units forward along
the suspension axis.
Friction The level of friction applied to the objects as they try to move relative
to each other along the suspension axis. Available with Havok 1 only.
Strength The strength value of the suspension spring. Higher values cause
less vertical movement. Available with Havok 3 only.
