To Roll a Ball using C# program in unity .

1. File -> Scene -> Select the scene -> Save as-> New folder(Scenes)-> File name (MiniGame)

2. Heirarchy -> 3D Object-> Plane [ Right side-> Inspector-> Change the name of plane (Name: Ground) Transform -> Reset Edit -> FrameSelected ]

3. Scale the ground by giving the scaling value as x=4 y=1 z=4

4. Heirarchy -> 3D Object-> Sphere [ Right side-> Inspector-> Change the name of plane (Name: Player) Transform -> Reset Edit -> FrameSelected Transform -> Position -> y=0.5]

5. Hierarchy -> DirectionalLight [ Inspector -> Change the color to white (255,255,255)]

6. Create a folder in project and name as Materials [Material folder -> Create -> Material (Name: Background) Inspector ->Surface Inputs ->BaseMAp (Choose the color) Metallic map-> 0 Smoothness -> 0.25 Drag the Background to the plane and release the mouse

Material folder -> Create -> Material (Name: Sphere) Inspector ->Surface Inputs ->BaseMAp (Choose the color) Metallic map-> 0 Smoothness -> 0.75 Drag the Sphere material to the ball and release the mouse

7. Hierarchy -> Player-> Inspector ->Add component-> Rigidbody

8. Create a new script -> Create a folder in project (Name: Scripts) Hierarchy -> Player -> Inspector-> AddComponent-> NewScripts-> PlayerController( Click create and Add) Copy the PlayerController and drag to Script folder Double click the PlayerController file and type the coding

            z = z - ZForce;
        }
        float y= 0.0f;
        if (Input.GetKeyDown(KeyCode.Space))
        {
            y = YForce;
        }
        GetComponent<Rigidbody>().AddForce(x, y, z);
    }
}

Thus, The 3D application for Roll the Ball objects in unity is developed successfully.
