Can't figure out IK aiming

I'm trying to make a C# for enemy to aim at player, but I don't know how to rotate the weapon:
In hierarchy, the weapon is inside the right hand. I tried the basic IK example at the unity documentation page.
I modified it and I have this:

Code (CSharp):

1. private void OnAnimatorIK()
2.     {
3.  
4.         animator.SetLookAtWeight(1);
5.         animator.SetLookAtPosition(PlayerTarget.position);
6.      
7.         animator.SetIKPositionWeight(AvatarIKGoal.RightHand, 1);
8.         animator.SetIKRotationWeight(AvatarIKGoal.RightHand, 1);
9.         animator.SetIKPosition(AvatarIKGoal.RightHand, PlayerTarget.position);
10.         animator.SetIKRotation(AvatarIKGoal.RightHand, PlayerTarget.rotation);
11.      
12.     }

The PlayerTarget is inside Player, but the gun isn't rotating at the player and it is modified by player rotation. If I turn around 180 the enemy's arm is also rotating the arm.
I tried to put the target outside the Player and make it follow player by script, but without rotation, only position. It isn't also working.

Do you have an IK enemy aiming a gun at player script?

Thanks!

Ok, but how exactly implement IK and rotation to make an enemey aiming?

 

Oh, sorry, my bad. I misread your post. But you can check out the tutorial, hopefully it helps a little. I'm too noob to give advice, sorry lol
