Hello,
I have had this problem for a while but I have not been able to find an answer. When the player gets within a certain distance, the enemy rotates and moves towards the player. When he within a closer distance, he stops so that he won’t run into the player. When he is within the second distance, he stops rotating. I have an archer so when he stops rotating he won’t be able to hit the player if he moves just inches from the side.
This is what I have got:
// vars
var target : Vector3;
public var dir : Vector3;
private var dirFull : Vector3;
public var mindist:float;
public var maxdist:float;
public var civilian:boolean;
public var Wander:boolean;
public var dist:float;
public var wayPoint : Vector3;
public var speed : float = 1;
public var WanderDistance:float;
public var pickPoint:boolean = true;
public var CantMove:boolean;
public var added:boolean;
public var size:float;
function Update()
{
var curY:float = transform.position.y;
//Find The Player/Distance
target = GameObject.FindGameObjectWithTag("Player").transform.position;
dist = Vector3.Distance(target, transform.position);
//Dont Want to shoot through walls.
var hit : RaycastHit;
//If it is between the maximum distance
if(dist < maxdist){
//the minimum distance
if(dist > mindist){
//direction to rotate
dir = (target - transform.position).normalized;
// check for forward raycast
if (Physics.Raycast(transform.position, transform.forward, hit, 20))
{
if (hit.transform != this.transform)
{
Debug.DrawLine (transform.position, hit.point, Color.white);
dir += hit.normal * 20; // 20 is force to repel by
}
}
// more raycasts
var leftRay = transform.position + Vector3(-0.125, 0, 0);
var rightRay = transform.position + Vector3(0.125, 0, 0);

//Stay on the same Y position
transform.position.y = curY;
}//Ends Minimum Distance

//Civilians run away
if(civilian == true){
rot = Quaternion.Inverse(rot);

//Ends Maximum Distance
}else{
//Wandering When out of range
PickPos();
transform.LookAt(wayPoint);
transform.position += transform.forward * speed * Time.deltaTime;
}
}
function PickPos()
{
if((transform.position - wayPoint).magnitude <= 3||pickPoint == true){
wayPoint= Random.insideUnitSphere *WanderDistance;
wayPoint.y = transform.position.y;
transform.LookAt(wayPoint);
pickPoint = false;
}
}
function OnCollisionEnter(hit:Collision){
