My sphere is not rotating

Questions & Answers

Hello!
In my game i have two spheres, and i move them via Rigidbody.AddForce but one sphere is the player, the second is the enemy.
When i move my player sphere via imput and addforce it rotates like in real life.
But my enemy sphere has a simple AI to look at player sphere and to move forward also via addforce, but the enemy is not rotating like the player. Why?

Here is the enemy shpere script:

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class EnemyController : MonoBehaviour {
	public float speed;
	private Rigidbody rb;

	public GameObject player;

	void Start () {
		rb = GetComponent<Rigidbody>();
	}

	void FixedUpdate () {
		transform.LookAt(player.transform);
		rb.AddForce (transform.forward * speed);
	}

	void OnCollisionEnter(Collision collision) 
	{
		if (collision.gameObject.CompareTag ( "Player"))
		{
			player.GetComponent<PlayerController>().winText.text = "You lose!";
			Time.timeScale = 0;
		}
	}
}

Well LookAt tells it to orient itself towards the player.

Remove LookAt, and use:

(player.transform.position - transform.position).normalized

Instead of transform.forward on the line below.
