Public Attributes

float32 dampingRatio
 The damping ratio. 0 = no damping, 1 = critical damping.
float32 frequencyHz
float32 length
 The natural length between the anchor points.
b2Vec2 localAnchorA
 The local anchor point relative to bodyA's origin.
b2Vec2 localAnchorB
 The local anchor point relative to bodyB's origin.

Detailed Description

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.
