Wave System Delay

Unity Engine
1

Hey guys, I’m working on a wave based zombie game. As of now I have the waves working perfectly. I would like to add a delay between waves and Im having no luck at all. Ive tried running a coroutine when the the enemiesKilled >= enemyAmount but it crashes my game. Any suggestions?

public int waveNumber = 0;
public int enemyAmount = 0;
public int enemiesKilled = 0;
public int randomEnemy;
public GameObject[ ] spawners;
public GameObject[ ] enemy;
public TextMeshProUGUI waveNumberText;
private void Start()
{
spawners = new GameObject[5];
for (int i = 0; i < spawners.Length; i++)
{
spawners = transform.GetChild(i).gameObject;
}
StartWave();
}
public void Update()
{
if (enemiesKilled >= enemyAmount)
{
NextWave();
}
waveNumberText.text = waveNumber.ToString(“0”);
}
public void SpawnEnemy()
{
int spawnerID = Random.Range(0, spawners.Length);
randomEnemy = Random.Range(0, enemy.Length);
Instantiate(enemy[randomEnemy], spawners[spawnerID].transform.position, spawners[spawnerID].transform.rotation);
}
public void StartWave()
{
waveNumber = 1;
enemyAmount = 6;
enemiesKilled = 0;
for (int i = 0; i < enemyAmount; i++)
{
SpawnEnemy();
}
}
public void NextWave()
{
waveNumber++;
enemyAmount += 4;
enemiesKilled = 0;
for (int i = 0; i < enemyAmount; i++)
{
SpawnEnemy();
}
}

When posting code to the forum, make sure to use Code Tags so other people can read it easier.

Do you get errors when it crashes? Or does it freeze and stop responding?

For a slight pause after all enemies are gone, I would use something like this:
