SceneManager.sceneLoaded

説明

Add a delegate to this to get notifications when a Scene has loaded.

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


In the script example below a number of method calls are shown. Specifically the first labelled method OnEnable() is used to add OnSceneLoaded (), which is not a Unity provided method. The SceneManager.sceneLoaded delegate can have any method hooked into it and it is OnSceneLoaded () here. Finally, OnDisable() is used to remove OnSceneLoaded () from SceneManager.sceneLoaded.

using UnityEngine;
using UnityEngine.SceneManagement;

public class ExampleCode : MonoBehaviour
{
    // called zero
    void Awake()
    {
        Debug.Log("Awake");
    }

    // called first
    void OnEnable()
    {
        Debug.Log("OnEnable called");
        SceneManager.sceneLoaded += OnSceneLoaded;
    }

    // called second
    void OnSceneLoaded(Scene scene, LoadSceneMode mode)
    {
        Debug.Log("OnSceneLoaded: " + scene.name);
        Debug.Log(mode);
    }

    // called third
    void Start()
    {
        Debug.Log("Start");
    }

    // called when the game is terminated
    void OnDisable()
    {
        Debug.Log("OnDisable");
        SceneManager.sceneLoaded -= OnSceneLoaded;
    }
}
