public class AI : CharacterClass {
public float shotRange = 15.0f;
public float playerRange = 5.0f;
public float distanceToShot = 10.0f;
public float walkingTime = 6.0f;
public float thinkingTime = 3.0f;

laser.SetPosition(1,new
Vector3(0f,0f,GUN_LASER_DISTANCE));

With the preceding code, we basically created all the necessary parameters for the
AI script. We also override the start function and set the laser length on the y -axis,
which is a bit different to our CharacterControl script in Chapter 5 , Build a
