Additional environmental features

We are now ready to enhance our terrain with additional features. First, we will add a natural bridge, and then we'll selectively plant trees. We'll also add water to the center of our terrain and create the sky.

Natural bridge

There are several ways to build a bridge for our game. We want the player to be able to walk from one side of the game map to the other. The approach we'll take is to use a textured geometric shape. Here are the steps:

1. Use the transform tools in the Scene view to zoom into the area you want to place the bridge. I will put it in the center of the terrain.
2. Select the GameObject drop-down menu, select the 3D Object, and click on Cube.
3. Right-click on the cube in the Hierarchy view and select Rename. Rename the cube as Bridge.
4. Use the transform tool to increase the width and length of the cube. A scale of 12, 5, 58 works nicely.
5. Use the translate tool to move the bridge in place. Be sure to place both ends just beneath the surface...
