@NoOffset
 @Properties(inherit=liquidfun.class)
public class b2DistanceJointDef
extends b2JointDef

Distance joint definition. This requires defining an anchor point on both bodies and the non-zero length of the distance joint. The definition uses local anchor points 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.

Initialize

public void Initialize(b2Body bodyA,
                       b2Body bodyB,
                       @Const @ByRef
                       b2Vec2 anchorA,
                       @Const @ByRef
                       b2Vec2 anchorB)

Initialize the bodies, anchors, and length using the world anchors.

localAnchorA

@ByRef
public b2Vec2 localAnchorA()

The local anchor point relative to bodyA's origin.

localAnchorA

public b2DistanceJointDef localAnchorA(b2Vec2 setter)

localAnchorB

@ByRef
public b2Vec2 localAnchorB()

The local anchor point relative to bodyB's origin.

localAnchorB

public b2DistanceJointDef localAnchorB(b2Vec2 setter)

length

@Cast(value="float32")
public float length()

The natural length between the anchor points.

length

public b2DistanceJointDef length(float setter)

frequencyHz

@Cast(value="float32")
public float frequencyHz()

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

frequencyHz

public b2DistanceJointDef frequencyHz(float setter)

dampingRatio

@Cast(value="float32")
public float dampingRatio()

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