# XRNode

> Enumeration of XR nodes which can be updated by XR input or sent haptic data.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.XR](/engine/6000.0/script-reference/unityengine/xr.md)
* **Assembly:** UnityEngine.XRModule

```csharp
public enum XRNode
```

## Remarks

**Note:** The types GameController, TrackingReference, and HardwareTracker are considered non-singleton nodes, as there can be many of each available.  As a result, [InputTracking.GetLocalPosition](/engine/6000.0/script-reference/unityengine/xr/inputtracking/getlocalposition.md), and [InputTracking.GetLocalRotation](/engine/6000.0/script-reference/unityengine/xr/inputtracking/getlocalrotation.md) will not work with those values.  Please use [InputTracking.GetNodeStates](/engine/6000.0/script-reference/unityengine/xr/inputtracking/getnodestates.md) instead. **Note:** Only XR nodes with valid haptic devices as endpoints can be sent haptic data.
