Enemy and Friendly AIs - Unity Game Development Scripting - page 114

AI towards the player. When Distance is less than 10 , we set the AI behavior to
Combat .
Now that our AI can run from the player as well as chase them down, let's utilize the
waypoints and create paths for the AI. Add this code to the empty Patrol function:
void Patrol()
{
Distance =
Vector3.Distance(gameObject.transform.position,
Waypoints[curWaypoint].position);
if(Distance > 2.00f)
{
Destination =
Waypoints[curWaypoint].position;
navAgent.SetDestination(Destination);
}
else
{
if(ReversePath)
{
if(curWaypoint <= 0)
{
ReversePath = false;
}
else
{
curWaypoint--;
Destination =
Waypoints[curWaypoint].position;
}
}
else
{
if(curWaypoint >= Waypoints.Length - 1)
{
ReversePath = true;
}
