14.3.5.1 Script Breakdown
The BaseWaypointFollower class derives from ExtendedCustomMonoBehavior, which
adds some extra functionality and common variables:
public class BaseWaypointFollower : ExtendedCustomMonoBehavior
{
As per most of the scripts in this topic, Start() calls Init():
public virtual void Start ()
{
if(!didInit)
Init();
}
Init() creates references to the transform and gameObjects, and the variable
AIController is set (GameObject.GetComponent() looks for BaseAIController):
public virtual void Init ()
{
// cache our transform
myTransform= transform;
// cache our gameObject
myGO= gameObject;
// cache a reference to the AI controller
AIController= myGO.GetComponent<BaseAIController>();
