How to get the scene an instance of a script is running in?

I am using a multi-scene design with additive scene loading, and I would like to be able to easily set the active scene by having a monobehavior script in the primary scene of the set that does something like this:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5.  
6. public class SceneActivator : MonoBehaviour {
7.  
8.     void Awake()
9.     {
10.         SceneManager.SetActiveScene(SceneManager.getCalledFrom());
11.     }
12. }
13.  

obviously, the function "getCalledFrom()" is a fictional function, but is there something like it that can find the scene of the monobehaviour that called it? Looking through the scenemanager function it looks like the best I could do is have a string tagged with [serializefield] that can be set through the editor and fed into the call. I would like to avoid having to manually configure this if possible though. Alternatively maybe something like this:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5.  
6. public class SceneActivator : MonoBehaviour {
7.  
8.     void Awake()
9.     {
10.         SceneManager.SetActiveScene(SceneManager.getSceneContainingGameObject(gameObject));
11.     }
12. }
13.  

where "getSceneContainingGameObject()" returns the scene that holds the game object passed in or null if it is a prefab? I can't find anything like this in unity though...

 

You can find out to which scene object relates by using gameObject.scene. It is "default" for prefabs.

Alternatively, check against scene.IsValid.

 

Thank you, this sounds like exactly what I was looking for!
