Animator - characters all run animation

Hi,
I have a problem with animator and various characters.
I have a couple of characters (prefabs from package).
There are various animations for them.
I prepared one Animator which runs walk-animation and if triggered runs dead-animation.
I connected this Animator to various characters.
I created one script that randomly sets target for a character and characters then moves towards this point.
I created script that detects when a character is hit and if hit (onMouseClick) then dead-animation plays.

The problem: when I click on one character the dead-animation plays for all other characters also (not only for this one).
How can I achieve the goal, which is play only dead animation on only one character.

script of the character:

Code (CSharp):

1. public class NPCScript : MonoBehaviour
2. {
3.  
4.     public Animator anim;
5.     // Start is called before the first frame update
6.     void Start()
7.     {
8.         anim = GetComponent<Animator>();
9.     }
10.  
11.  
12.     void setDying()
13.     {
14.         currentState = 3;
15.         anim.SetInteger(animatorMovingStateName, currentState);
16.     }
17.  
18.     void Update()
19.     {
20.         if (Input.GetMouseButtonDown(0))
21.         {
22.             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
23.             RaycastHit hit;
24.  
25.             if (Physics.Raycast(ray, out hit))
26.             {
27.                 if (hit.transform.name == "NPC")
28.                 {
29.                     setDying();
30.                 }
31.             }
32.         }
33.     }
34. }

 

problem solved. all NPC`s run the Update code - then all run setDying() animation. It should be only run by NPC that received the hit.
