Constraint Base Params
Editor Properties: (see get_editor_property/set_editor_property)
contact_distance(float): [Read-Write] Determines how close to the limit we have to get before turning the joint on. Larger value will be more expensive, but will do a better job not violating constraints. A smaller value will be more efficient, but easier to violate.
damping(float): [Read-Write] Damping of the soft constraint. Only used when Soft Constraint is on.
restitution(float): [Read-Write] Controls the amount of bounce when the constraint is violated. A restitution value of 1 will bounce back with the same velocity the limit was hit. A value of 0 will stop dead.
soft_constraint(bool): [Read-Write] Whether we want to use a soft constraint (spring).
stiffness(float): [Read-Write] Stiffness of the soft constraint. Only used when Soft Constraint is on.
