SceneManager.sceneUnloaded

Description

Add a delegate to this to get notifications when a Scene has unloaded

Rather than being called directly this script code shows use of a delegate. This means the sceneUnloaded value is added into a list of delegates.

In the script example below a method call is shown. Specifically a function called OnSceneUnloaded is added to sceneUnloaded. SceneUnloaded is called when the scene it is associated with is closed. At this point SceneUnloaded should be removed from the sceneUnloaded list.

#pragma strict
public class SceneLoaded1 extends MonoBehaviour {
	public function Start() {
		SceneManager.sceneUnloaded += OnSceneUnloaded;
		Debug.Log("Start: SceneLoaded1");
	}
	private function OnSceneUnloaded(current: Scene) {
		Debug.Log("OnSceneUnloaded: " + current);
	}
	function Update() {
		if (Input.GetKey("space")) {
			Debug.Log("Quitting Scene1");
			ChangeScene();
		}
	}
	function ChangeScene() {
		Debug.Log("Changing to Scene2");
		SceneManager.LoadScene("Scene2");
	}
	function OnDestroy() {
		Debug.Log("OnDestroy");
	}
}

using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneLoaded1 : MonoBehaviour
{
    public void Start()
    {
        SceneManager.sceneUnloaded += OnSceneUnloaded;
        Debug.Log("Start: SceneLoaded1");
    }

    private void OnSceneUnloaded(Scene current)
    {
        Debug.Log("OnSceneUnloaded: " + current);
    }

    void Update()
    {
        if (Input.GetKey("space"))
        {
            Debug.Log("Quitting Scene1");
            ChangeScene();
        }
    }

    void ChangeScene()
    {
        Debug.Log("Changing to Scene2");

        SceneManager.LoadScene("Scene2");
    }

    void OnDestroy()
    {
        Debug.Log("OnDestroy");
    }
}

SceneLoaded2 simply announces that this is the active scene.
