JointMotor class Physics
A spring-damper drive on a single GenericJoint axis.
The motor pulls the axis toward targetPosition with spring constant stiffness and toward targetVelocity with damping, applying at most maxForce (a force on a linear axis, a torque on an angular one). Leave stiffness at 0 for a pure velocity drive; set it for a positional spring (a soft constraint).

-
Damping constant pulling the axis toward targetVelocity.

- hashCode → int
-
The hash code for this object.

- maxForce → double
-
Maximum force (linear axis) or torque (angular axis) the motor may
apply. double.infinity leaves it unlimited.

-
A representation of the runtime type of the object.

- stiffness → double
-
Spring constant pulling the axis toward targetPosition.
final
- targetPosition → double
-
Rest position the spring pulls toward: meters on a linear axis,
radians on an angular one.
final
- targetVelocity → double
-
Velocity the damper drives toward: meters per second or radians per
second.
