# init(pin0:pin1:distanceLimit:checksForInternalCollisions:)

Creates a new distance joint.

## Declaration

```swift
init(pin0: GeometricPin, pin1: GeometricPin, distanceLimit: ClosedRange<Float>, checksForInternalCollisions: Bool = false)
```

## Parameters

- `pin0`: The local position and orientation on the first entity.
- `pin1`: The local position and orientation on the second entity.
- `distanceLimit`: Specifies the minimum and maximum allowed distance between the two pins.
- `checksForInternalCollisions`: A Boolean that indicates whether the joint checks for collisions between the two doc://com.apple.RealityKit/documentation/RealityKit/Entity instances.
