A damped spring

Instance Methods

__init__(self, a, b, anchr1, anchr2, rest_length, stiffness, damping)
Defined much like a slide joint.

__del__(self) (Inherited from pymunk.constraint.Constraint)

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

Properties
	anchr1
	anchr2
	rest_length The distance the spring wants to be.
	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)
Inherited from `object`: `__class__`

Method Details

init(self, a, b, anchr1, anchr2, rest_length, stiffness, damping)
(Constructor)

Defined much like a slide joint.

Parameters:

rest_length (float) - The distance the spring wants to be.
stiffness (float) - The spring constant (Young's modulus).
damping (float) - How soft to make the damping of the spring.

Overrides: object.__init__
