Time for action – creating a ground plane

It's usually easier to walk around when you've got a floor underneath you, so let's start by creating a ground plane using the following steps:

1. In the Hierarchy panel, click on Create | 3D Object | Plane.
2. Rename the GameObject to Ground in the Inspector tab:
   • Change the Scale to 3 in the X, Y, and Z axes:

3. If the lighting in your scene looks dimmer or different from the preceding screenshot, increase the Intensity value of the Directional Light component as follows:

We created a plane GameObject and increased its size to make more room for our future character to walk around. This plane will act like a 3D object bound by real-life physics, meaning other objects can't just fall through. We'll talk more about the Unity physics system and how it works in Chapter 7, Movement, Camera Controls, and Collisions. Right now, we need to start thinking in 3D.
