Follow player using NavMesh.CalculatePath() and CharacterController?

Hi, I'm trying to have an AI follow my player using the nav mesh path without using a NavMeshAgent, but a CharacterController instead.

I have managed to get the path that the AI should follow, but I am struggling to properly make it move along this path towards the player. My current code in the Update function looks like this:

Code (CSharp):

1.         elapsed += Time.deltaTime;
2.         if (elapsed > 0.5f)
3.         {
4.             elapsed -= 0.5f;
5.             NavMesh.CalculatePath(transform.position, player.position, NavMesh.AllAreas, path);
6.         }
7.  
8.  
9.         Vector3 firstPointDirection = path.corners[1] - transform.position;
10.  
11.         controller.Move(new Vector3(firstPointDirection.x, gravity, firstPointDirection.z) * speed * Time.deltaTime);

Which I thought made sense because it updates so frequently perhaps it should just move towards the first point? However, this just makes the enemy appear to rubber band as in a laggy multiplayer title towards the player. Any suggestions on how to properly do this using the CharacterController Move function? Thank you.

 

Anyone?

 

I find it usefull, thanks!
