// Start is called before the first frame update

IEnumerator SpawnMonsters()

    while (true)

        spawnedMonster = Instantiate(monsterReference[randomIndex]);

        // left side
        if (randomSide == 0)
        {
            spawnedMonster.transform.position = leftPos.position;
            spawnedMonster.GetComponent<Monster>().speed = Random.Range(4, 10);

        }

            spawnedMonster.GetComponent<Monster>().speed = -Random.Range(4, 10);
            spawnedMonster.transform.localScale = new Vector3(-1f, 1f, 1f);

        } // while loop
