# minimumDistance

The minimum value for distance-based effects.

## Declaration

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

## Discussion

Discussion This property determines the beginning of the field’s falloff area. At distances less than the minimum, the field’s effect is at full strength. At greater distances, the field’s effect diminishes based on the value of the falloffExponent property. The default minimum distance is a very small (but nonzero) value.
