Obstacle avoidance?

Hello EVERYBODYYY

Im trying to make an enemy obstacle avoidance script, and I found this online:
#pragma strict

// Avoid Obstacle Script
// ---------------------

var speed : float = 10.0;
var target : Vector3 = Vector3(0, 0, 0);
private var dir : Vector3;
private var dirFull : Vector3;

// ----

function FixedUpdate()
{
    // -- Obstacle Avoidance Tutorial --

    // the directional vector to the target
    dir = (target - transform.position).normalized;
    var hit : RaycastHit;

    // check for forward raycast
    if (Physics.Raycast(transform.position, transform.forward, hit, 1)) // 20 is raycast distance
    {
       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);

    // check for leftRay raycast
    if (Physics.Raycast(leftRay, transform.forward, hit, 1)) // 20 is raycast distance
    {
       if (hit.transform != this.transform)
       {
         Debug.DrawLine (leftRay, hit.point, Color.red);

         dir += hit.normal * 20; // 20 is force to repel by
       }
    }

    // check for rightRay raycast
    if (Physics.Raycast(rightRay, transform.forward, hit, 1)) // 20 is raycast distance
    {
       if (hit.transform != this.transform)
       {
         Debug.DrawLine (rightRay, hit.point, Color.green);

         dir += hit.normal * 20; // 20 is force to repel by
       }
    }

    // --

    // Movement

    // rotation
    var rot = Quaternion.LookRotation (dir);

    //print ("rot : " + rot);
    transform.rotation = Quaternion.Slerp (transform.rotation, rot, Time.deltaTime);

    //position
    transform.position += transform.forward * (2 * Time.deltaTime); // 20 is speed

    // -- end tutorial --

}

Well, i can say IT WORKS!! BUT, I want the enemy to chase the player than a point in the map. Javascript is not my area. Anybody help with this?

PS: I saw:
var target : Vector3 = Vector3(0, 0, 0);

but i dont know how to change this into a gameobject!

help…?

ye’r diff’r’nt :V

First, hit Control+H (find and replace). Change “target” to “target.position”.

Now go back to the variable declaration and change it to “var target : Transform;”

You’ll need to assign it in the Inspector or use a GameObject.Find variant to find the right object at runtime.
