Class Hierarchy

• object: The most base type
  • pymunk.Arbiter: Arbiters are collision pairs between shapes that are used with the collision callbacks.
  • pymunk.BB: Simple bounding box class. Stored as left, bottom, right, top values.
  • pymunk.Body: A rigid body
  • pymunk.constraint.Constraint: Base class of all constraints.
    • pymunk.constraint.DampedRotarySpring: Like a damped spring, but works in an angular fashion
    • pymunk.constraint.DampedSpring: A damped spring
    • pymunk.constraint.GearJoint: Keeps the angular velocity ratio of a pair of bodies constant.
    • pymunk.constraint.GrooveJoint: Similar to a pivot joint, but one of the anchors is on a linear slide instead of being fixed.
    • pymunk.constraint.PinJoint: Keeps the anchor points at a set distance from one another.
    • pymunk.constraint.PivotJoint: Simply allow two objects to pivot about a single point.
    • pymunk.constraint.RatchetJoint: Works like a socket wrench.
    • pymunk.constraint.RotaryLimitJoint: Constrains the relative rotations of two bodies.
    • pymunk.constraint.SimpleMotor: Keeps the relative angular velocity of a pair of bodies constant.
    • pymunk.constraint.SlideJoint: Like pin joints, but have a minimum and maximum distance. A chain could be modeled using this joint. It keeps the anchor points from getting to far apart, but will allow them to get closer together.
  • pymunk.Contact: Contact information
  • pymunk.SegmentQueryInfo: Segment queries return more information than just a simple yes or no, they also return where a shape was hit and it's surface normal at the hit point. This object hold that information.
  • pymunk.Shape: Base class for all the shapes.
    • pymunk.Circle: A circle shape defined by a radius
    • pymunk.Poly: A convex polygon shape
    • pymunk.Segment: A line segment shape between two points
  • pymunk.Space: Spaces are the basic unit of simulation. You add rigid bodies, shapes and joints to it and then step them all forward together through time.
  • unreachable._CData: XXX to be provided
    • _ctypes.Structure: Structure base class
      • pymunk.vec2d.Vec2d: 2d vector class, supports vector and scalar operators, and also provides some high level functions
