Chapter 2. Let's Start with the Sky
So, you've downloaded and cracked the seal on a fresh copy of Unity. You've seen some examples of what other people have done with the game engine, and you've taken a whirlwind tour of the interface. You can clear out the Angry Bots Demo project by clicking on File | New Project in the menu. After choosing an empty folder for the new project (you can call it Intro), Unity will close down completely and start up again. Once it does, you're left staring at a 3D plane.
Click on the little landscape icon at the top middle of the Scene view to see this plane, as shown in the following screenshot. It stretches on forever in all directions—seemingly infinitely to either side of you, ahead of you, behind you, straight down to the deepest depths, and straight up to the sky.
It's time to build a game, right? But how do you start? Where do you start?
