C# Class FarseerPhysics.Dynamics.Joints.FixedPrismaticJoint

A prismatic joint. This joint provides one degree of freedom: translation along an axis fixed in body1. Relative rotation is prevented. You can use a joint limit to restrict the range of motion and a joint motor to drive the motion or to model joint friction.

Method Description
FixedPrismaticJoint ( Body body, System.Vector2 anchor, System.Vector2 axis ) : System

This requires defining a line of motion using an axis and an anchor point. The definition uses local anchor points and a local axis so that the initial configuration can violate the constraint slightly. The joint translation is zero when the local anchor points coincide in world space. Using local anchors and a local axis helps when saving and loading a game.
