# SKPhysicsJointSliding

A joint that allows two physics bodies to slide along an axis.

```
class SKPhysicsJointSliding
```

## Overview

An [`SKPhysicsJointSliding`](/documentation/SpriteKit/SKPhysicsJointSliding) object allows the anchor points of the two physics bodies to slide along a chosen axis. The joint can be configured to limit the distance that the two objects are allowed to slide along the axis.

## Topics

### Creating a Sliding Joint

[`joint(withBodyA:bodyB:anchor:axis:)`](/documentation/SpriteKit/SKPhysicsJointSliding/joint(withBodyA:bodyB:anchor:axis:))

Creates a new sliding joint.

### Configuring a Sliding Joint

[`shouldEnableLimits`](/documentation/SpriteKit/SKPhysicsJointSliding/shouldEnableLimits)

A Boolean value that indicates whether the sliding joint is restricted so that the objects may only slide a finite distance from the initial anchor point.

[`lowerDistanceLimit`](/documentation/SpriteKit/SKPhysicsJointSliding/lowerDistanceLimit)

The smallest distance allowed for the sliding joint.

[`upperDistanceLimit`](/documentation/SpriteKit/SKPhysicsJointSliding/upperDistanceLimit)

The largest distance allowed for the sliding joint.
