Trying to add a delay to an Instantiate in a For Loop
Hello, i am pretty new in unity coding with C#.
I try to code a spawn manager with an index of different prefabs that make random wave with a for loop making more and more enemies each new wave.
It's working well dispite one thing : enemies often spawn at the same position and that make them collide and glitch and i would like to make them spawn (be instantiate) not all at the same time during a wave, make them spawn one by one after a short delay (0.5seconds for exemple). The goal is to have wave of 50 enemies, so its important to don't make them spawn at the same time.
I tried use IEnumerator and Coroutine with wait for seconds in many ways in the code but it never worked properly (no enemies spawns or i get inifinity of enemies)
How do i have to use WaitForSeconds properly for this code or maybe there is another way to do it ?
PS : ObjectsOfType is a script attached to all enemies that i use to count enemies in this script.
thank you in advance
using System.Collections;
using System.Collections.Generic;

public class SpawnManagerXaxisTest : MonoBehaviour
{
public GameObject[] enemyPrefabs;
public float spawnRangeZ = 20;
public float spawnPosX = 20;
public int enemyCount;
public int waveNumber = 1;
private void Start()
{
SpawnRandomEnemy(waveNumber);
}
void SpawnRandomEnemy(int enemiesToSpawn)
{
int enemyIndex = Random.Range(0, enemyPrefabs.Length);
for (int i = 0; i < enemiesToSpawn; i++)
{
Instantiate(enemyPrefabs[enemyIndex], GenerateSpawnPosition(),
enemyPrefabs[enemyIndex].transform.rotation);
}
}
void Update()
{
enemyCount = FindObjectsOfType<MoveMiddle>().Length;
if (enemyCount == 0)
{
waveNumber++;
SpawnRandomEnemy((waveNumber));
}
}
private Vector3 GenerateSpawnPosition()
{
Vector3 spawnPos = new Vector3(spawnPosX, 1, Random.Range(-spawnRangeZ, spawnRangeZ));
return spawnPos;
}
}
