# particleRotationRange

The range of allowed random values for a particle’s initial rotation, expressed as an angle in radians.

## Declaration

```swift
var particleRotationRange: CGFloat { get set }
```

## Discussion

Discussion The default value is 0.0. If non-zero, the initial rotation of each particle is randomly determined and may vary by plus or minus half of the range value.
