How to Overriding Monobehaviour Messages ? (Solved)

Hello Unity!

Guess the title says everything!
Here what I'm trying to say:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. public class A : MonoBehaviour {
4.   void Update () {
5.     Debug.log("Main class");
6.   }
7. }

And my second class inherits from it:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. public class B : A {
4.   // TODO: how to do this override in the messages?
5.   protected override void Update () {
6.     base.Update() // <= this here doesn't work.
7.     Debug.log("B as A");
8.   }
9. }

How to override the monobehaviour messages ?

 

Make the update in class A virtual:

Code (CSharp):

1. public class A : MonoBehaviour
2. {
3.     // Update is called once per frame
4.     protected virtual void Update()
5.     {
6.         Debug.Log("Base class A");
7.     }
8. }
9.  
10. public class B : A
11. {
12.     // Update is called once per frame
13.     protected override void Update()
14.     {
15.         base.Update();
16.         Debug.Log("Child class B");
17.     }
18. }

Verified with Unity 5, I expect it also works with 4.6
