Can someone tell me how to make a particle system play when hitting an animal?

Hi, I am currently creating a small survival game, and I want to know how I can make a particle system play when I hit an animal. I am new to programming, so if anyone could help me I would appreciate that.

Here is my script

     public float maxHealth, maxThirst, maxHunger;
     public float thirstIncreaseRate, hungerIncreaseRate;
     private float health, thirst, hunger;
     public bool dead;
 
     public GameObject player;
     public float[] position;
 
     public float damage;
     public bool weaponEquipped;
     public bool toolEquipped;
     public static bool triggeringWithAI;
     public static GameObject triggeringAI;
 
     public static bool triggeringWithTree;
     public static GameObject treeObject;
 
     public static bool triggeringWithOre;
     public static GameObject oreObject;
 
     [Header("Audio")]
 
     public AudioSource aud;
     public AudioSource swingAud;
     public AudioClip swing;
     public AudioClip impactAnimalAud;
     public AudioClip impactTreeAud;
     public AudioClip impactOreAud;
 
     [Header("UI Components")]
 
     public Text healthText;
     public Text thirstText;
     public Text foodText;
 
     public void Start()
     {
         health = maxHealth;
     }
 
     public void Update()
     {
         healthText.text = health.ToString();
         thirstText.text = thirst.ToString();
         foodText.text = hunger.ToString();
 
         if (!dead)
         {
             hunger += hungerIncreaseRate * Time.deltaTime;
             thirst += thirstIncreaseRate * Time.deltaTime;
         }
 
         if (thirst >= maxThirst)
             Die();
         if (hunger >= maxHunger)
             Die();
 
         //print(thirst);
         //print(hunger);
         //print(health);
 
         //detecting and killing ai
         if (triggeringWithAI == true && triggeringAI)

         }
 
         if (!triggeringAI)
             triggeringWithAI = false;

you can have an empty object on every weapon, position it to the place where you want the particles toplay.

 public void OnTriggerEnter(Collider other)
          {
              if (other.tag == "Animal")
              {
                  triggeringAI = other.gameObject;
                  triggeringWithAI = true;
                   particlesystem.transform.position = weaponHitPos;
                   particlesystem,Play();
              }
          }
