Метод Instantiate не всегда вызывается

Gamedev и графика Unity

У меня есть объект и на нём прикреплён такой скрипт

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemyTrigger : MonoBehaviour
{
    [SerializeField] private EnemyMove enemyMove;
    [SerializeField] private GameObject deathEffect;
    [SerializeField] private GameObject damageEffect;
    [SerializeField] private GameObject pointEffect;
    [SerializeField] private GameObject damageSound;
    [SerializeField] private GameObject pointSound;
    [SerializeField] private float timeBeforeDeath;
    [SerializeField] private int damage;

    private PlayerController player;
    private TextManager textManager;

    private bool isCollision = false;



    private void Start()
    {
        textManager = FindObjectOfType<TextManager>();
        player = FindObjectOfType<PlayerController>();
    }

    private void OnTriggerExit2D(Collider2D collision)
    {
        if(collision.CompareTag("Enemy"))
            Invoke("Death", timeBeforeDeath);
    }

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Point"))
        {
            isCollision = true;
            Instantiate(pointEffect, transform.position, Quaternion.identity);
            Instantiate(pointSound, transform.position, Quaternion.identity);
            textManager.point++;
            Destroy(gameObject, 0.01f);
        }
        if (collision.CompareTag("Player") && isCollision == false)
            CollisionFunc();
        if (collision.CompareTag("Enemy") && isCollision == false)
            CollisionFunc();
    }

    private void CollisionFunc()
    {
        Instantiate(damageEffect, transform.position, Quaternion.identity);
        Instantiate(damageSound, transform.position, Quaternion.identity);
        player.TakeDamage(damage);
        enemyMove.speed = 0f;
        transform.parent = player.transform;
    }

    private void Death()
    {
        Instantiate(deathEffect, transform.position, Quaternion.identity);
        Instantiate(pointSound, transform.position, Quaternion.identity);
        Destroy(gameObject);
    }
}

И вот именно

            Instantiate(pointEffect, transform.position, Quaternion.identity);

            Instantiate(damageEffect, transform.position, Quaternion.identity);

            Instantiate(deathEffect, transform.position, Quaternion.identity);

Вызываются не всегда, почему?
