Question by ao196419 · May 28, 2017 at 03:15 PM · scene-loadingscene-switchingstartscene loadscene change

Start function not called after reloading scene

Hi! So I have 2 scenes that are switched back and forth from time to time. However, when a scene is loaded the second time, its Start function is not called. Here is a part of the code:

 using UnityEngine;
 using UnityEngine.UI;
 using UnityEngine.SceneManagement;
 
 public class StartScene : MonoBehaviour {
 
     IEnumerator loading(){    
         AsyncOperation loadLevel = SceneManager.LoadSceneAsync ("Maze");
         while (!loadLevel.isDone) {
             yield return null;
         }        
     }
 
     void Start () {
         Debug.Log ("Hi this is Start()");
     }

     void Update () {
         if (Input.GetKeyDown ("enter") || Input.GetKeyDown ("return")) {
             StartCoroutine (loading ());
         }
     }
 

The line of code Debug.Log ("Hi this is Start()"); is not executed if the code have been loaded before.

Things that I tried:

  1. Use SceneManager.UnloadSceneAsync("StartScene"); to delete all GameObject before switching to the next scene.

  2. Use this to delete all GameObjects before switching to the next scene.

    foreach (GameObject o in Object.FindObjectsOfType<GameObject>()) { Destroy(o); }

  3. Put this.gameObject.GetComponent<StartScene> ().enabled = true; in Awake().

But nothing works :( Any help will be greatly appreciated!
