Rigidbody enemy Forcemode.VelocityChange

Hello there, I am trying to make a simple enemy that looks and chases the player with a constant velocity using Rigidbody ForceMode.VelocityChange, at the begining it works well but for some reason the enemy follows another direction, what am I doing wrong?!

ex:

var velo = 1.0;

function FixedUpdate () {

   var Player = gameObject.FindWithTag("Player").transform;

   transform.LookAt(Vector3(Player.position.x,transform.position.y,Player.position.z)); 
   rigidbody.AddRelativeForce(transform.forward * velo, ForceMode.VelocityChange);

}

try using
transform.LookAt(Player);
instead of that long line
alsi use Vector3.forward instead of transform.forward (though it might not make a difference)

the script would be:
var velo : float = 1.0;

function FixedUpdate () 
{
   var player = gameObject.FindWithTag("Player").transform;

   transform.LookAt(player); 
   rigidbody.AddRelativeForce(Vector3.forward * velo, ForceMode.VelocityChange);

}

If this won’t work tell me :wink:
