# SCNParticleInputMode.overDistance

The controller’s effect on a particle property is a function of the particle’s distance from the position of a specified node.

## Declaration

```swift
case overDistance
```

## Discussion

Discussion Use the inputOrigin property to specify the node to measure distance from, and the inputBias and inputScale properties to refine the relationship between a range of distances into a range of input values for the controller’s animation.
