# NINearbyObjectAngleNotAvailable

A value that indicates that a nearby object’s horizontal angle is unavailable.

```
extern float NINearbyObjectAngleNotAvailable;
```

## Discussion

The framework sets [`horizontalAngle`](/documentation/NearbyInteraction/NINearbyObject/horizontalAngle-9ibky) to the value of this property when it’s unable to acquire the nearby object’s horizontal angle at any given time.
