Please, I need help, I'm trying to create a Coroutine where my enemy shoots 1 pack of 4 bullets, every 2 seconds, but it just ended up in the enemy shooting some bullets and then never again

Questions & Answers

IEnumerator Shoot()
{
while(quantBullet <= 4)
{
GameObject bullet = Instantiate(bulletPrefab, shotSpawner.position, shotSpawner.rotation);
Rigidbody2D rb = bullet.GetComponent();
rb.AddForce(shotSpawner.up * bulletForce, ForceMode2D.Impulse);
quantBullet++;
yield return new WaitForSeconds(2f);

        if (quantBullet == 4)
        {
            pack = true;
        }

        if(pack == true)
        {
            yield break;
        }
        yield return null;
    }
}

IEnumerator Shoot()
{
while(true)
{
quantBullet = 0;
while(quantBullet < 4)
{
GameObject bullet = Instantiate(bulletPrefab, shotSpawner.position, shotSpawner.rotation);
Rigidbody2D rb = bullet.GetComponent();
rb.AddForce(shotSpawner.up * bulletForce, ForceMode2D.Impulse);
quantBullet++;
yield return new WaitForSeconds(.2f);
}

        yield return new WaitForSeconds(2.0f);
    }
}

Only call StartCoroutine(Shoot()) one time per enemy.
