# particleScaleRange

The range of allowed random values for a particle’s initial scale.

## Declaration

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

## Discussion

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