DistanceJoint2D距离二维关节

Namespace: UnityEngine

Namespace: UnityEngine/Inherits from:AnchoredJoint2D

Joint that keeps two Rigidbody2D objects a fixed distance apart.

关节，使两个二维刚体对象保持在一个固定的距离。

Note that unlike the SpringJoint2D component, the distance separating the objects is truly fixed and does not allow for any stretching.

注意与弹簧二维关节组件不同的是，分开的物体的距离被切实固定，并且不允许任何拉伸。

autoConfigureDistance	Should the distance be calculated automatically? 是否自动计算距离？
ditance	The distance separating the two ends of the joint. 关节的两端分开的距离
maxDistanceOnly	Whether to maintain a maximum distance only or not. If not then the absolute distance will be maintained instead. 是否仅支持一个最大距离。如果不支持，绝对距离将被支持替代。
