Wave manager that enables multiple gameobjects after X seconds?

Hey there everyone, I could use some help.

I want to have a WaveManager that would enable new gameobjects (wavecontrollers that would spawn in the in the enemies). So basically, having a WaveManager that enables multiple objects at different times. It should be able to enable multiple gameobjects after X seconds in one Wave. The problem is that I'm not able to access the waveControllers gameobjects nor the timer int.

For example

• The Wave 1 class in the Inspector would Enable the Wave1 gameobjects after X seconds.

• The Wave 2 class in the Inspector would Enable the Wave2 gameobjects after X seconds.

The script would just keep on enabling the different wave game objects after X seconds. I started something that I think should work, but I'm not too sure on how to do it.

 //This allows for multiple waves each with their own
 //unique timer and game object waveControllers
 [System.Serializable]
 public class Wave
 {
     public int timer;
     public GameObject[] waveControllers;
 }

 IEnumerator WaveTimer(Wave _wave)
 {
     yield return new WaitForSeconds(timer);
     //Enables the new waveController that is after the
     //one before it
 }

If you need more information or anything like that, please let me know. I could really use some help with this.
