Getting list of all opened scenes

Unity Engine
1

Hi, I can see there is EditorSceneManager.loadedSceneCount, but I can’t find function that returns all opened scenes, anyone knows if there is such function at all?

Nevermind, SceneManager.GetAllScenes returns all loaded scenes, it’s just not documented.

In case anyone runs into this as I did, here’s the new way:

        int countLoaded = SceneManager.sceneCount;
        Scene[] loadedScenes = new Scene[countLoaded];

        for (int i = 0; i < countLoaded; i++)
        {
            loadedScenes[i] = SceneManager.GetSceneAt(i);
        }

Note: SceneManager.GetAllScenes() is deprecated (not sure if it was in Feb 2016) and the suggested new solution is above.

Why the heck was it deprecated? Everybody’s just going to add their own GetOpenScenes() method using the above method…

It was probably deprecated because it allocates an array. Unity is generally moving away from any API call that allocates so that devs can manage and avoid needless allocations and GC. At least with the custom class, you can manage the memory and cache the scene list to avoid unnecessary allocations.
