How do I call function in inhereted script?

Question

Kind of like how Unity calls Awake() in a script inheriting from MonoBehaviour, I want to call Initialize() and Execute() in any scripts inheriting from Ability.cs. How can I do this in C#?

The function you're looking to call in the parent script must be public, then just call it as you would any other function.

 using UnityEngine;
 using System.Collections;
 
 public class Parent : MonoBehaviour 
 {
     public void ParentFunction()
     {
         Debug.Log("Parent function was called!");
     }
 }
 
 using UnityEngine;
 using System.Collections;
 
 public class Child : Parent 
 {
     // Use this for initialization
     void Start () 
     {
         ParentFunction();
     }
 }

um, the commenter above answered your question - his answer contains 2 scripts, Parent and Child.

Although I'd like to amend his answer - the function you're calling in the parent script doesn't have to be public, it can also be protected if you're only calling it from a child class.

Or, if you mean 'how do I call function Foo(), implemented in Parent, when I have a reference to Child, and want to call it from Other?

Then you can do

 public class Other : MonoBehaviour {
 
 public Parent parent;
 public Child child;
 
 
 void Call(){
  //both of these methods work!
  parent.Foo();
  child.Foo();
 
 }

}

If you want to call a method Bar() that is only implemented in Child, though, it gets a little trickier.

You can either do something like

 Child c = parent as Child;
 if(c) c.Bar();

Or you could make an abstract Bar() method in Parent.

I'm confused. I don't know if the child has Foo(), only that the parent has Foo(). Basically, I want to have a moddable ability system for each player that I can drag and drop certain scripts onto. Each ability will inherit from the class 'Ability' and will have the function Execute(). I don't know that the child will be called Child; it could be called FireBall, MagicMissile, etc. but the main thing is it has the function Execute() and I need to call Execute() from the GameManager; not from the child or whatever. It's okay; I actually got the answer here: http://gamedev.stackexchange.com/questions/97358/callback-on-derived-class.
