Namespace: UnityEngine/Inherits from:AnchoredJoint2D
Joint that attempts to keep two Rigidbody2D objects a set distance apart by applying a force between them.
关节，尝试通过应用它们之间的力量使两个 Rigidbody2D 对象设置的距离。
Note that unlike DistanceJoint2D, the length of the joint can stretch and oscillate.
请注意与 距离二维关节不同、 关节的长度可拉伸和摆动。
|autoConfigureDistance||Should the distance be calculated automatically?
|dampingRatio|| The amount by which the spring force is reduced in proportion to the movement speed.
|distance|| The distance the spring will try to keep between the two objects.
|frequency|| The frequency at which the spring oscillates around the distance between the objects.
