Inheritance hides Start()

Questions & Answers
1

Inheriting from a base class that inherits from monobehavior hides Start() in the base class if you use it in the derived class. As well as a lot of other monobehavior functions.

How can I have Start() work in both classes?

This seems to work for me…?

using UnityEngine;
using System.Collections;

public class ManyBase : MonoBehaviour {
  public void Update () {
  }
  public virtual void Start() {
    Debug.Log("Hello");
  }
}

public class Many2 : ManyBase {
  public override void Start ()
  {
    base.Start ();
    Debug.Log ("World");
  }
  public void OnGUI() {
    var style = new GUIStyle();
    style.normal.textColor = Color.white;
    style.fontSize = 12;
    GUI.Label(new Rect(10f, 10f, 2f, 0.5f), "Hello World", style);
  }
}

Just remember that a MonoBehaviour isn’t valid unless it defines both Start() and Update(). If your parent class only defines start, and the child does not define Update() its not a valid behaviour and wont be executed.
