5.3.1 Script Breakdown
The class derives from ExtendedCustomMonoBehavior (as discussed in Chapter 4), which
adds a few commonly used variables.
Each WheelCollider variable is named based on its intended position: front-
WheelLeft, frontWheelRight, rearWheelLeft, and rearWheelRight. For the script to
function correctly, WheelColliders need to be referenced (dragged and dropped) into
the correct variables in the Unity Inspector window on the vehicle script:
using UnityEngine;
using System.Collections;
public class BaseVehicle : ExtendedCustomMonoBehavior
{
public WheelCollider frontWheelLeft;
public WheelCollider frontWheelRight;
public WheelCollider rearWheelLeft;
public WheelCollider rearWheelRight;
