# rollingFriction

The body’s resistance to rolling motion.

## Declaration

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

## Discussion

Discussion This property simulates the traction between a rounded body and bodies it might roll against. A rolling friction of 0.0 (the default) means that a body induced to roll (for example, by being placed on an inclined surface) will continue to roll without slowing down unless otherwise acted upon, and a rolling friction of 1.0 prevents the body from rolling.
