C# 클래스 FarseerPhysics.Dynamics.Joints.DistanceJoint

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.

메소드	설명
DistanceJoint ( Body bodyA, Body bodyB, Vector2 anchorA, Vector2 anchorB, bool useWorldCoordinates = false ) : 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.
getReactionForce ( float invDt ) : Vector2	Get the reaction force given the inverse time step. Unit is N.
getReactionTorque ( float invDt ) : float	Get the reaction torque given the inverse time step. Unit is N*m. This is always zero for a distance joint.

프로퍼티 상세

dampingRatio 공개적으로 프로퍼티

The damping ratio. 0 = no damping, 1 = critical damping.

public float dampingRatio
리턴	float

frequency 공개적으로 프로퍼티

The mass-spring-damper frequency in Hertz. A value of 0 disables softness.

public float frequency
리턴	float

length 공개적으로 프로퍼티

The natural length between the anchor points. Manipulating the length can lead to non-physical behavior when the frequency is zero.
