Field Detail

localAnchorA

public final Vec2 localAnchorA

The local anchor point relative to body1's origin.

localAnchorB

public final Vec2 localAnchorB

The local anchor point relative to body2's origin.

referenceAngle

public float referenceAngle

The body2 angle minus body1 angle in the reference state (radians).

frequencyHz

public float frequencyHz

The mass-spring-damper frequency in Hertz. Rotation only. Disable softness with a value of 0.

dampingRatio

public float dampingRatio

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