Q. Are assets and game objects the same?
A. Not exactly. Basically the big difference is that assets have a corresponding file or group of files on the hard drive, whereas a game object does not. An asset may or may not contain a game object.
Q. There are a lot of different controls and options. Will I need to memorize them all right away?
A. Not at all. Most controls and options will already be set to a default state that covers most situations. As your knowledge of Unity grows, you can continue to learn more about the different controls that you have available to you. This chapter is just meant to show you what’s there and to give you some level of familiarity.
