Enemies spawning on top of each other fix?

Questions & Answers

Hello,
I want to fix my script, but I don’t know exactly how to do it and I’ve been googling for awhile now and I haven’t found any help.
I want 3 types of enemies to respawn, but sooner or later the enemies are spawning on top of each other.
What could I use for a solution?

Here’s my script: Enemywave.cs

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

public class Enemywave : MonoBehaviour
{

	public Transform enemy1;
	public Transform enemy2;
	public Transform enemy3;
	public float SpawnCount = 3f;

	public float WaveCount = 3f;

	private int EnemyNum=0;

	public Transform whereSpawn;
	// Use this for initialization
	void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
		if (WaveCount <= 0)
		{
			StartCoroutine(EnemyWaveCount());
			EnemyWaveCount();
			WaveCount = SpawnCount;
		}

		WaveCount -= Time.deltaTime;
	}

	IEnumerator EnemyWaveCount()
	{
		EnemyNum++;
		for (int i = 0; i < EnemyNum; i++)
		{
			Enemy1Spawner();
			yield return new WaitForSeconds(1f);
			Enemy2Spawner();
			yield return new WaitForSeconds(3f);
			Enemy3Spawner();
			yield return new WaitForSeconds(5f);
		}
		
		
	}

	void Enemy1Spawner()
	{
		Instantiate(enemy1,whereSpawn.position,whereSpawn.rotation);
		
	}

	void Enemy2Spawner()
	{
		Instantiate(enemy2, whereSpawn.position, whereSpawn.rotation);
	}

	void Enemy3Spawner()
	{
		Instantiate(enemy3, whereSpawn.position, whereSpawn.rotation);
	}
}

What can I do or use in order not to make the enemies to spawn on top of each other?
Thank you

First why is this a thing?

             StartCoroutine(EnemyWaveCount());
             EnemyWaveCount(); // This one won't be called and should be causing a warning

Second, EnemyNum seems to be a big issue. It will eventually, create a ton of dudes, and goes against the point of the EnemyWaveMethod. Just get rid of the entire for loop.

IEnumerator EnemyWaveCount()
     {
         EnemyNum++; // This never gets decremented and will eventually get really large

Lastly, your enemies share the same spawn point. You could make whereSpawn an array of points around a map, but you would still get spawns on top of each other. I would instead spawn your enemies randomly around the spawn point. Something like:

float distance = 5; // whatever you want the circle size to be
Vector3 spawnPoint = whereSpawn.Position+ Random.insideUnitCircle * distance;
