//put into two monobehaviours in unity if you want to run it, and put AwakeChild on a gameobject.

using System.Collections;

using UnityEngine;

public class AwakeBase : MonoBehaviour {

	protected bool setup = false;
	Transform thisWillBeNullInChild;

	void Awake()
	{
		setup = true;
		thisWillBeNullInChild = GetComponent<Transform>();

		DoWork();
	}

	public virtual void DoWork()
	{
		//this is where you would put your overrideable setup code
		Debug.Log("Base work. Okay to override this.");
	}
		
}



//Class two, child

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

public class AwakeChild : AwakeBase {

	//The developer does not know that AwakeBase implements Awake,
	//and so does not know that they should call base.Awake()
	//comment out Awake or add base.Awake() to see how it works
	void Awake()
	{
		if (setup)
		{
			Debug.Log("I am setup");
		}
		else
		{
			Debug.Log("I am not setup");
		}
	}

	//but we want them to override DoSetup
	//ideally they don't override Awake() above, and only use this DoWork method:
	public override void DoWork ()
	{
		//now you can write code here that will be called
		Debug.Log("Child work called in Awake");
	}

	//however we can't enforce that? (This is the problem I want to enforce or make the developer explicity use "new")
