Importing and animating the background

In this section, we are going to get familiar with Unity's animator controller. We will make our player's ship travel at light speed (well, give the impression that it is, anyway) by creating a fast-moving background of stars and particles (yes, that's right, more particles) at the start of the level, then we'll slow everything down when there are enemies up ahead.

Before we start animating at "light speed," we need to prepare the Hierarchy window:

1. In the Hierarchy window, right-click on an open-space area.
