Like a damped spring, but works in an angular fashion
Instance Methods
 
__init__(self, a, b, rest_angle, stiffness, damping)
Like a damped spring, but works in an angular fashion.
 
__del__(self) (Inherited from pymunk.constraint.Constraint)

Inherited from object: __delattr__, __format__, __getattribute__, __hash__, __new__, __reduce__, __reduce_ex__, __repr__, __setattr__, __sizeof__, __str__, __subclasshook__

Properties
  rest_angle
The relative angle in radians that the bodies want to have
  stiffness
The spring constant (Young's modulus).
  damping
How soft to make the damping of the spring.
  a
The first of the two bodies constrained (Inherited from pymunk.constraint.Constraint)
  b
The second of the two bodies constrained (Inherited from pymunk.constraint.Constraint)
  bias_coef
The percentage of error corrected each step of the space. (Inherited from pymunk.constraint.Constraint)
  max_bias
The maximum speed at which the constraint can apply error correction. (Inherited from pymunk.constraint.Constraint)
  max_force
The maximum force that the constraint can use to act on the two bodies. (Inherited from pymunk.constraint.Constraint)
