GetSceneByName returns null

To switch between levels, I built some code that takes the current scene name (formatted like 'Level 1') and increases the number on the end each time, so it can load the next level.

When I load the next level, I check that a scene with that name is valid, and if so load it. If not, it returns to the menu instead.

GetSceneByName keeps returning null, so when I check if the scene is valid, it says it's not. Obviously the scene is there, it's in the build settings, but the code keeps returning null.

In the documentation there's a bit I don't understand about GetSceneByName checking an exact file path in some cases, or just looking at the end of the scene names...

Code (CSharp):

1. //check if next level exists
2. Scene sceneCheck = SceneManager.GetSceneByName (nextLevel);
3. if (sceneCheck.IsValid ())
4.     SceneManager.LoadScene (nextLevel);
5. else
6.     SceneManager.LoadScene ("Level Select");

 

two things, the docs state it searches through the scenes that are already loaded, so I wouldn't expect the above to work?

so, what are you passing as nextLevel? and are the scenes in build settings?

 

All the scenes are in the build settings. 'nextLevel' is a string that is the name of the level I want to load. But sometimes, it won't exist, which is why I'm trying to use the isValid check on it first.

Ok, yes. I just tested it with a different scene, and realised maybe I was doing it differently when it worked. I have changed that code quite a few times now.
