# particleZPositionRange

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

## Declaration

var particleZPositionRange: CGFloat { get set }
```

## Discussion

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