# init(settlingDuration:dampingRatio:epsilon:)

Creates a spring with the specified duration and damping ratio.

```
init(settlingDuration: TimeInterval, dampingRatio: Double, epsilon: Double = 0.001)
```

## Parameters

`settlingDuration`

The approximate time it will take for the spring
to come to rest.

`dampingRatio`

The amount of drag applied as a fraction of the amount
needed to produce critical damping.

`epsilon`

The threshhold for how small all subsequent values need to
be before the spring is considered to have settled.
