### Example

The example shows how to create a finger joint with the `FingerJoint` class.

#### Create a finger joint with the specified 2D position and 3D position

```csharp
FingerJoint indexTip = new FingerJoint
(
    FingerJointType.IndexTip,
    new Vector2(3, 3),
    new Vector3(0.3f, 0.3f, 0.3f),
    new Quaternion()
);
```

#### Create a finger joint with the specified finger joint

```csharp
FingerJoint indexTipNew = new FingerJoint(indexTip);
```

#### Create an empty finger joint

</strong></code></pre>
