New Game Mechanics For Roll a Ball

So for my game roll, a ball that would change it up from its original code is that  I would add the bouncingSphere to have the sphere to bounce up and down when the cube would have the ability to bounce up and down as well with the PingPong code but would also mostly used bouncingSphere with the sphere (https://docs.unity3d.com/ScriptReference/BoundingSphere.html).
