# minimumAngularLimit

The minimum rotation angle between the two bodies, measured in radians relative to their initial orientations.

## Declaration

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

## Discussion

Discussion The default (and minimum) value of this property is -M_PI. With this value, the joint can spin clockwise (relative to the first body) with no limit. Set both this property and the maximumAngularLimit property to the same value to prevent the bodies from rotating around their anchor points. (Set both properties to 0.0 to fix the bodies in their initial orientations.) Bodies whose orientation is fixed by a sliding joint may still slide, depending on the values of the minimumLinearLimit and maximumLinearLimit properties.
