The Smart Car AI demo
Now, we'll start setting up our driving demo that will have a car driving along a road
and avoiding obstacles.
Setting up a Unity test scene
Besides needing Smart Car, we'll need an environment for our AI cars to drive in.
We'll use Car Tutorial v1.3 that is made by Unity, which you can download for free
from the Asset Store. Import the project and open
TheTrack
scene from the impor-
ted
Scenes
folder. Next, add a car to the scene. The car prefab that comes with Car
Tutorial doesn't have the complete wheel physics setup, so you can configure it us-
ing the steps in the last section or use the
EnemyAICar
prefab from Smart Car. To
make the car work better with the
Tutorial
scene, extend the rays a little, set
Wide
and
Tight Ray Distance
both to
40
and
Long Ray Distance
to
50
. This keeps the
car from hitting obstacles when going too fast and missing tight turns. Once you have
a car in the scene configured for Smart Car, select the
Main_Camera
object and set
your car to
Target
for the
Car Camera
script.
If you start the demo now, the car still won't run but the main camera in the scene will
follow it:

Main_Camera
game object of Car Tutorial. These are the
settings for the
TheTrack
scene with
Target
set to the Smart Car prefab.
