In Unity, Is it possible to get gameobjects from non-open Scene?

Question

Sorry for my english mistakes,I treid my best to make myself easy to be understood.

On Unity 2017.1 + C#.

I am trying to make UnitTest to check the potential errors in the scenes. and when I want to get the gameObjects from the two deifferent scenes, I can only get the scene which is open currently in the editor.

How to solve this problem? Or This is impossible to be done in Unity mechanism?

Two Secens I have:

Scene1 hierarchy:

Scene2 hierarchy:

Code:

Result: Only get the open scene's infomation

---

My Final Solution

Thanks for the help, you guys help me make progress.

This is the feedback of my work. When I tried to solve my problems with the instruction, I ran into some obstacle.

So, I followed the suggestion of the error message.

And the result is pleasant.

The possible reason I can not get the same result at the begining, It may be because the different test mode(playMode/EditMode)

I will let myself take a break now and not dig deeper at this moment.

Thanks for your help and wish my dicovery can help someone too.

Answer 1

You are trying to get scene information before loading the scene try this it worked for me.

        [Test]
        public void Test_loadScene()
        {

            SceneManager.LoadScene(0);
            Scene scen_1 = SceneManager.GetSceneByBuildIndex(0);
            SceneManager.LoadScene(1);
            Scene scen_2 = SceneManager.GetSceneByBuildIndex(1);

            Debug.Log("Scene 1 name: " + scen_1.name);
            Debug.Log("Scene 2 name: " + scen_2.name);
        }

Result:

Debug:

Make sure both scene are added to "Scene in build"

Answer 2

Hey there I see you are a new contributor. First off let me say that you can paste code directly in your question and that is desired. Secondly Have you tried loading both scenes before performing the test with :

SceneManager.LoadScene("scene_name", LoadSceneMode.Additive);
