load scene - some time (2 seconds) after object is destroyed in Unity

Question

How do I check if an object has been destroyed. And do something like change scenes 2 seconds later.

this is what I tried:

float delay = 2

void OnDestroy(){

 delay-= Time.deltaTime;
 if(delay<=0){
   Application.LoadLevel("scene2");
  }
}

Answer 1

you can use another script(for example GameManager) because when gameObject Destroyed haven't script component for checking if Delay <= 0

using UnityEngine;
using System.Collections;

public class MyObject: MonoBehaviour {

void Start(){
    Destroy (gameObject);

}

void OnDestroy(){
    GameManager.Instance.StartCoroutine ("Delay");

    }
 }

using UnityEngine;
using System.Collections;

public class GameManager : MonoBehaviour {
    public static GameManager Instance;


    void Awake () {
        Instance = this;
    }

    IEnumerator Delay(){
        yield return new WaitForSeconds (2);
        print ("that works");
        Application.LoadLevel ("scene2");
    }
}

or you can use Invoke for delay

using UnityEngine;
using System.Collections;

public class MyObject : MonoBehaviour {

    void Start(){
        Destroy (gameObject);
    }

    void OnDestroy(){
        GameManager.Instance.Invoke ("Delay", 2);

    }
}

using UnityEngine;
using System.Collections;

public class GameManager : MonoBehaviour {
    public static GameManager Instance;

    void Awake () {
        Instance = this;
    }

    void Delay(){
        print ("that works");
        Application.LoadLevel ("scene2");
    }
}
