The RollingResistance property of the Surface class controls how easily rolling shapes, such as spheres and capsules, roll on surfaces. This property is crucial for simulating realistic physical interactions between rolling objects and the surfaces they interact with.

To use the RollingResistance property, you can get or set its value to adjust the rolling behavior of shapes on a surface. The value should be between 0 and 1, where 0 means no resistance (objects roll freely) and 1 means maximum resistance (objects do not roll).

Example usage:

Surface mySurface = new Surface();
mySurface.RollingResistance = 0.5f; // Sets the rolling resistance to a moderate level
float resistance = mySurface.RollingResistance; // Retrieves the current rolling resistance value
