Can't I use coroutine without a Monobehaviour?

I want to use Coroutine in my script. But I couldn't use "StartCoroutine" because I didn't inherit MonoBehaviour.

As far as I know, I have to inherit Monobehaviour to use Coroutine. But now I can't inherit Monobehaviour. Is there any way to use Coroutine in this situation? The same goes for the Invoke function.

Coroutine doesn't work without MonoBehaviour, but if you want to use Coroutine in non-MonoBehaviour class you can transmit MonoBehaviour class in constructor or create empty MonoBehaviour to run coroutines on them. It`s will looks like:

pubclic class CoroutineHost : MonoBehaviour{}


public class NonMonoClass
{
   private CoroutineHost _host;
   NonMonoClass()
   { 
       _host = new GameObject("CoroutineHost")
          .AddComponent<CoroutineHost>();
   }

   public void RunYourCoroutine()
   {
       _host.StartCoroutine(nameof(YourCoroutine));
   }

   // Here is should be your coroutine logic
   private IEnumerator YourCoroutine();

    //Finalizer need to destroy  gameobject 
    //when non-mono class will be ready for garbage collection.
   ~NonMonoClass()
   {
       _host.StopAllCoroutines();
       GameObject.Destroy(_host.gameobject);
       _host = null;
   }
}

I will call what you want to achieve: a Coroutine Management feature and my understanding is that you want to include that feature inside your non-MonoBehaviour class. But thanks to my Remember quote above you cannot do it right now.

But including it in-side a .dll might be possible as a .dll can contain many classes. And you can use Access Modifiers to enforce your rules (the internal modifier is my favorite).

If I were you I would treat Coroutine Management as a separate problem and would build a .dll to handle them separately so that it would not mess up with my game-play business.
