How to get scene name at certain buildIndex

Questions & Answers

There is way to get currently loaded scene name by Application.loadedLevelName, but is there a way to get a name of the scene at certain buildIndex or a name of the scene that is at current buildIndex + 1?

I managed to figure this out. Here you go, future googlers:

private static string NameFromIndex(int BuildIndex)
{
    string path = SceneUtility.GetScenePathByBuildIndex(BuildIndex);
    int slash = path.LastIndexOf('/');
    string name = path.Substring(slash + 1);
    int dot = name.LastIndexOf('.');
    return name.Substring(0, dot);
}

System.IO.Path.GetFileNameWithoutExtension(SceneUtility.GetScenePathByBuildIndex(yourBuildIndex));

GetScenePathByBuildIndex returns the path and GetFileNameWithoutExtension returns the name of the file without the path and extension. So the result of this line is the exact scene name as per the given index you’ve given

Cheers :slight_smile:

Came looking for the same issue, and got hung up on the SceneManager handling already loaded scenes, which didn’t necessarily help. Here’s the solution I came up with:

public static string GetSceneNameFromBuildIndex(int index) {
   string scenePath = SceneUtility.GetScenePathByBuildIndex(index);
   string sceneName = System.IO.Path.GetFileNameWithoutExtension(scenePath);

   return sceneName;
}

I think the only access point is mentioned here:

The 5.5b documentation states, that a EditorBuildSettingsScene only has a path as the only string information. The exampled from the link above makes use of the AssetDatabase class to get the full path which contains the name of the level (acutally I don’t know if not the path from EditorBuildSettingsScene already contains that).
Nevertheless, it seems a little complicated, but that’s the best I came up with.

There is an easier way:

private static string GetSceneNameByIndex(int buildIndex)
{
    if(buildIndex > SceneManager.sceneCountInBuildSettings - 1)
    {
        Debug.LogErrorFormat("Incorrect buildIndex {0}!", buildIndex);
        return null;
    }

    var scene = SceneManager.GetSceneByBuildIndex(buildIndex);
    return  scene.name;
}

private static string GetNextSceneName()
{
    return GetSceneNameByIndex(SceneManager.GetActiveScene().buildIndex + 1);
}
