# PhysicsRevoluteJoint

A joint that allows one degree of rotational freedom between two entity pins, similar to a door swinging on its hinges.

## Declaration

```swift
struct PhysicsRevoluteJoint
```

## Overview

Overview PhysicsRevoluteJoint allows one rotational degree of freedom along the x-axis of two entity pins. tip: Pass an orientation when creating the GeometricPin instances to change the axis of rotation.
