# bounce

How bouncy the spring is.

## Declaration

```swift
var bounce: Double { get }
```

## Discussion

Discussion A value of 0 indicates no bounces (a critically damped spring), positive values indicate increasing amounts of bounciness up to a maximum of 1.0 (corresponding to undamped oscillation), and negative values indicate overdamped springs with a minimum value of -1.0.
