The Friction property of the SliderJoint class represents the frictional force applied to the slider joint. This property is a float value that determines how much resistance is applied to the sliding motion along the joint's axis. 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 applied to the slider joint. This can be useful for simulating realistic physical interactions where friction plays a role, such as in mechanical systems or when simulating surfaces with varying roughness.

Example usage:

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