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 AngryBots Demo project by clicking on File | New Project in the menu. After choosing a folder for the new project (you can call it "Intro"), Unity may close down completely and start up again. Once it does, you're left staring at a 3D plane.
Click the little landscape button at the top-middle of the Scene view to see this plane. 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?
