libGDX 1.14.2 · com.badlogic.gdx.physics.box2d.joints.DistanceJointDef

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.
