Summary

The Roll-a-ball Project is a simple rolling ball game that teaches you many of the principles of working with Unity.
The 2nd of 4 tutorials in the project demonstrates how to create a new Unity project, add some "primitive" shapes, and create a new material to change the color of the shapes. Then, we implement physics and add a simple C# script to let the player control the ball with the keyboard.
