How to make the object face towards first person controller?

I want to make some sort of animation where when I approach a model object, it turns and faces me, how would I go on about doing that?

 

You can go about it couple ways:
(1) - set a trigger that is triggered as the object is approached then start the animation sequence (Direction turn).
(2) - set up a distance check, when the distance is less than a value of your choice (nearing object), start the animation sequence and have the object turn toward whatever.

There are many ways you can go about it, those listed above are (in my opinion) the quickest and easiest options.

 

I found a way to accomplish this by using a look rotation script, which basically transforms the object to face the assigned target.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class RotatePos : MonoBehaviour {
5.     public Transform target;
6.     void Update() {
7.         Vector3 relativePos = target.position - transform.position;
8.         Quaternion rotation = Quaternion.LookRotation(relativePos);
9.         transform.rotation = rotation;
10.     }
11. }
12.  

However, I am having a slight problem, when I approach this object, there seems to be some sort of collider which blocks my path to walk in. Is there any way to disable this?
