FPS - Move Head where Player looks

Hello,
i am working on a PUN-Multiplayer FPS.
I want that the head (or neck, the results should look similar) moves up and down with the FPS camera.
I tried to rotate the head transform, but it seems to interfere with the idle animation.
So the head doesnt care and it doesnt rotate like i want, it rotates only like the idle animation rotates it.
I tried to do a animation for the head, too.
In the animation menu i created a new animation, added the heads transform as component and in the last keyframe i changed its rotation, but it jumps back to the default values in the animation menu.
I'm new to Unity, i hope this is the right section, and i hope you understand my description.
Sincerely,
IlluminatiGaming

 

For that you usually use IK (inverse kinematics). See IK tutorials and use http://docs.unity3d.com/ScriptReference/Animator.SetLookAtPosition.html
Simple code should be

Code (CSharp):

1. using UnityEngine;
2.  
3. public class HeadRotation : MonoBehaviour
4. {
5.     public Transform target;
6.     Animator anim;
7.     void Start()
8.     {
9.         anim = GetComponent<Animator>();
10.     }
11.     void OnAnimatorIK()
12.     {
13.         anim.SetLookAtPosition(target);
14.     }
15. }

Make sure in your Animator Controller layer's IK is enabled (in layers small gear - "IK Pass")
P.S. Didn't test code. Before 5.0 unity it required PRO version if you're using old versions.

 

Thanks for your answer.
I've heard of IK, but i thought it would still require Unity Pro.
I managed to got the head to work.
I had to add Animator.NeckDownUP or something similar and the click on record, and go to the last animation keyframe and next to the Name i could type in a little uppercase number.
So i created one animation looking up, one looking forward and one looking down.
Smashed togehter in a blend tree.
The value for the blend tree is then calculated from camera.transform.localRotation.
thanks for the answer, will be probably useful with more complex stuff

 

COOL ! Thanks Man!
