How to get an AI to look at player without Navmesh ?

I'm currently using lookAt but it does not work because when the player passes the 270* angle the enemy rotates all the way in the opposite direction to face the player instead of just turning 1*.

All the tuts I've seen only show AI navigation and rotation on the Navmesh Agent, but I need to seperate the AIs movement and rotational destinations.
I'm still a rookie with Quaternions and Vectors, can someone please offer some insight to making an object look at something else without the weird problems mentioned above, thanks.

 

Can you use; http://docs.unity3d.com/ScriptReference/Vector3.RotateTowards.html instead?

 

Hello,
I think i can recognize your problem.You can do the code instead of "lookat".
Here is the code:
var target : Transform;
function Update ()
{
var relativePos = target.position - transform.position;

var rotation = Quaternion.LookRotation(relativePos);

transform.rotation = rotation;

}

looking forward to your reply.

Thanks

 

It did not work because the AI is rotating on all axis, and now is floating (even with rigidbody attatched).

I tried transform.rotation.y = rotation.y. But that did not work because like mentioned before it causes the object to stop tracking when the player moves into the 250* spot.

I need for th AI to only rotate on the Y axis towards the players general area, I've been experimenting for a while and not much is working, any advice is welcome

Edit : NavMeshAgent.Move
I have temporarily found a fix for this problem but it is still not well suited for what I'm doing.

 

Example using a character controller - but the Vector functions could be used the same way without CharacterControllers

Code (CSharp):

1. public float movementSpeed = 0.03f;
2. public Vector3 movementVelocity = Vector3.zero;
3. public float turnRate = 1.11f;
4.  
5. CharacterController cmp_cc;          
6.  
7.     void Start ()
8.     {
9.         cmp_cc = GetComponent<CharacterController>();
10.     }
11.  
12.    //move player one step (movement speed) toward a point
13.     public void moveToward( Vector3 targetPoint)
14.     {
15.  
16.         Quaternion rotation = Quaternion.LookRotation(targetPoint - transform.position);
17.         rotation.x = 0f; //don't change (x) up/down rotation
18.         rotation.z = 0f; //don't change (z) side rotation
19.         transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * turnRate);
20.  
21.         Vector3 movementVelocity = transform.forward * movementSpeed;
22.  
23.         movementVelocity.y = -.08f; //apply some gravity
24.  
25.         cmp_cc.Move ( movementVelocity );
26.  
27.     }

 

Solved, setting the rotation.x and rotation.z to 0 solved the problem I was having with the AI not rotating properly on an individual axis. I thought of trying that method before but I thought it wouldn't work because it would be the same as setting: transform.rotation.y = rotation.y;
But it seems that weren't the case - thanks for the help
