C# Class FarseerPhysics.Dynamics.Joints.FixedDistanceJoint

A distance joint rains two points on two bodies to remain at a fixed distance from each other. You can view this as a massless, rigid rod.

Public Methods

Method	Description
FixedDistanceJoint ( Body body, Vector2 bodyAnchor, Vector2 worldAnchor ) : System	This requires defining an anchor point on both bodies and the non-zero length of the distance joint. If you don't supply a length, the local anchor points is used so that the initial configuration can violate the constraint slightly. This helps when saving and loading a game. @warning Do not use a zero or short length.
