LookAt() Makes object teleport around?

Unity Engine

Hello. My problem is that when I run my game and the monster who walks toward the player gets “too” close (which isn’t close enough for me) start ‘‘teleporting’’ around. I have already added a rigidbody and froze the Y axis… doesen’t seem to help… So it just like teleports around and goes through ground etc. And the player can’t rly get close to it… :confused: And ghost should be able to touch the player. Here’s the code. Thank you for all the help in advance! ^ ^

#pragma strict
var player : GameObject;
var MovementSpeed:float;

function Start () {
}

function Update () {
transform.LookAt (player.transform);
transform.Translate (0,0,MovementSpeed*Time.deltaTime);
}

Try setting the rigidbody to isKinematic.

How about this (attach script to enemy)

    Transform playerTransform;
    float speed = 1;
    float turnSpeed = 50;

    void Start()
    {
        playerTransform = GameObject.FindGameObjectWithTag("Player").transform;
    }

    void Update()
    {
        //rotate enemy facing player 
        Vector3 relativePos = playerTransform.position - transform.position;
        Quaternion newRotation = Quaternion.LookRotation(relativePos);
        transform.rotation = Quaternion.RotateTowards(transform.rotation, newRotation, Time.deltaTime * turnSpeed); 
    }

    void FixedUpdate()
    {
        rigidbody.AddRelativeForce(Vector3.forward * speed, ForceMode.Impulse);

        //limit max speed
        if (rigidbody.velocity.magnitude > speed)
            rigidbody.velocity = rigidbody.velocity.normalized * speed;
    }
