# SCNPhysicsHingeJoint

A physics behavior that connects two bodies and allows them to pivot around each other on a single axis.

## Declaration

```swift
class SCNPhysicsHingeJoint
```

## Overview

Overview A hinge has a single degree of freedom (rotation). You can also use a hinge joint to pin a body so that it can only move by rotating around a specific axis in the coordinate space of the node containing it.
