Making the old Scene "inactive" - how to handle persistent objects?

I have a Game Object that marked as "do not delete" so it will stick around when a new Scene is loaded. This seems to be an old Unity concept maybe? With newer Scene Manager code, you can load a new Scene async and then tell the original Scene to become inactive when the new one is loaded. Is there a way to make a persistent object come over to the new Scene instead of just stopping running when it's in the inactive Scene?

 

I'm not sure about "old Unity concept"; I think it's still a valid option.

However, there is: https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.MoveGameObjectToScene.html

If that's what you want.

 

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

 

I'm already using that. But it doesn't appear to continue running scripts on a game object that's in the "inactive" scene once it becomes inactive. Is that normal? I thought that it might be.

 

Thanks, would there be an event I could use there to wire that up that tells me when the Scene is done loading async?

 

There are built-in events for scene loaded, unloaded, and active scene changed. I think beyond that, you'd have to create your own.

Just out of curiosity, does your object get destroyed when you load a new scene and unload the old one or just stop running your scripts? I haven't a lot of experience with that, so just wondering.
Maybe I'd check that out some time to see.

 

that is not normal scripts on objects that use

DontDestroyOnLoad(this.gameObject);

should continue to run after the new scene is loaded and the old one removed i made a simple test i can share if u like

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.SceneManagement;
3. public class Save : MonoBehaviour
4. {
5.     private static bool created = false;
6.     void Awake()
7.     {
8.         if (!created)
9.         {
10.             DontDestroyOnLoad(this.gameObject);
11.             created = true;
12.             Debug.Log("Awake: " + this.gameObject);
13.         }
14.     }
15.     [ContextMenu("LoadScene")]
16.     public void LoadScene()
17.     {
18.         SceneManager.LoadSceneAsync(1, LoadSceneMode.Single);
19.     }
20.     public void FixedUpdate()
21.     {
22.         Debug.Log("Update");
23.     }
24. }
