# PhysicsDistanceJoint

A joint that maintains a minimum and maximum distance between two entity pins.

## Declaration

```swift
struct PhysicsDistanceJoint
```

## Overview

Overview A distance joint restricts the distance between pin0 and pin1. The joint determines this closed range according to distanceLimit. This joint allows full rotational freedom between pin0 and pin1.
