The Friction property of the SliderJoint class represents the frictional force applied to the slider joint. This property determines how much resistance is applied to the sliding motion between the two connected objects. A higher friction value will result in more resistance, slowing down the movement, while a lower value will allow for smoother and faster sliding.

To use the Friction property, you can get or set its value to control the frictional force of the slider joint. This can be useful in scenarios where you need to simulate realistic physical interactions between objects, such as simulating a drawer sliding open or a door sliding along a track.

Example usage:

SliderJoint sliderJoint = new SliderJoint();
sliderJoint.Friction = 0.5f; // Set the friction to a moderate level
float currentFriction = sliderJoint.Friction; // Retrieve the current friction value
