# animationSpeed

The rate at which the animation should proceed.

## Declaration

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

## Discussion

Discussion For noise and turbulence fields, this property contains the speed at which to animate the field. For all other fields, the value of this property is always 0.0. A value of 1.0 means the field animations occur at normal speed. Values less than 1.0 result in animations that are slower than normal, and values greater than 1.0 result in animations that are faster than normal. A value of 0.0 means that the field does not animate at all.
