Implementing the core classes for

mission one

In this chapter, we will start creating mission one, which presents US geography to the
player (state name, flag, and trivia). Let's begin by creating the classes and GameOb-
ject instances for this level. To begin, create a new scene file and name it TESTBED .

Creating a terrain

Let's create a nice terrain mesh to replace the ground plane from the previous two
levels. With this, we can create a nice-looking mesh for the ground that resembles a
park with grass, mountains, and trees by performing the following steps:

1. In the Assets menu, navigate to Import Package | Terrain Assets . Click on
the Import button on the pop-up window that appears next to bring a library of
models and textures into Unity for use with the terrain editor.
2. To create a terrain mesh, let's navigate to CreateOther | Terrain , from the
GameObject drop-down list.
3. On the Set Heightmap resolution pop up that appears, configure the para-
meters to the following values:

• Terrain Width , Terrain Length : The horizontal dimensions of the ter-
rain mesh. Set both to 500 units.
• Terrain Height : The maximum height of the terrain (for mountains and
so on). Set this to 500 units.
• The remaining parameters control the resolution of the textures that
are painted onto the terrain. Keep these at their defaults.
