Script function affecting multiple/all prefabs

Unity Engine
1

Hello,

I have an enemy manager script that goes on all my enemies.

int Health = 0;

    /// <summary>
    /// Apply damage to the enemy.
    /// </summary>
    /// <param name="Damage">The amount of damag to apply.</param>
    /// <param name="DamageType">The type of damage to apply.</param>
    public void TakeDamage(int Damage, DamageTypes DamageType = DamageTypes.Slashing)
    {
        if(stats != null)
        {
            switch (DamageType)
            {
                case DamageTypes.None:
                    break;
                case DamageTypes.Bludgenoning:
                    Health = Mathf.Clamp(Health - (Damage * stats.BludgeoningMultipler), 0, stats.MaxHealth);
                    break;
                case DamageTypes.Piercing:
                    Health = Mathf.Clamp(Health - (Damage * stats.PiercingMultipler), 0, stats.MaxHealth);
                    break;
                case DamageTypes.Slashing:
                    Health = Mathf.Clamp(Health - (Damage * stats.SlashingMultipler), 0, stats.MaxHealth);
                    break;
                case DamageTypes.Fire:
                    Health = Mathf.Clamp(Health - (Damage * stats.FireMultipler), 0, stats.MaxHealth);
                    break;
                case DamageTypes.Acid:
                    Health = Mathf.Clamp(Health - (Damage * stats.AcidMultipler), 0, stats.MaxHealth);
                    break;
                case DamageTypes.Ice:
                    Health = Mathf.Clamp(Health - (Damage * stats.IceMultipler), 0, stats.MaxHealth);
                    break;
                default:
                    break;
            }
        }



        //After taking damage check the health
        CheckHealth();
    }

    /// <summary>
    /// Check to see if the enemy's health has been reduced to 0. If so remove the enemy.
    /// </summary>
    void CheckHealth()
    {
        if(Health <= 0)
        {
            Die();
        }
    }

    /// <summary>
    /// Destroy the character.
    /// </summary>
    void Die()
    {
        Destroy(gameObject);
    }

I also have a weapon with a box collider as a trigger that does this:

private void OnTriggerEnter2D(Collider2D collision)
    {
        if(collision.gameObject.CompareTag("Enemy"))
        {
            EnemyManager enemyManager;
            if(collision.gameObject.TryGetComponent<EnemyManager>(out enemyManager) && weaponData != null)
            {
                enemyManager.TakeDamage(weaponData.Damage, weaponData.DamageType);
                
                
            }
        }
  
    }

but it affects all the enemies. They all die when one dies. What is making this happen? I appreciate the help.

I don’t see anything that would cause all enemies to die at once in this code. Check the colliders, you may be hitting all enemies at once. Also, it seems that the enemies start with 0 health.
