# parallaxFactor

A value that specifies how slowly the background should move relative to the foreground.

## Declaration

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

## Discussion

Discussion A large parallaxFactor value causes the background to move more slowly compared to the foreground. A small value makes the foreground and background move at a similar pace. The parallax effect becomes more apparent as the value of parallaxFactor increases. The default value of this property is 0.8. The minimum value is 0.0.
