SceneManager.GetAllScenes() only returns the current scene

Question

I've got a project where I simply want to put a scene menu. Here's the code:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.SceneManagement;
 
 public class PickScene : MonoBehaviour {
     Scene[] Scenes;
     
     // Use t$$anonymous$$s for initialization
     void Start () {
         Scenes = SceneManager.GetAllScenes();
     }
     
     // Update is called once per frame
     void Update () {
 
     }
 
     void OnGUI()
     {
         Debug.Log(SceneManager.GetAllScenes().Length);
         for (int i = 0; i < Scenes.Length; i++)
         {
             if (GUI.Button(new Rect(10, i*50,300,45), Scenes[i].name))
             {
                 SceneManager.LoadScene(i);
             }
         }
     }
 }

Works as expected, with no errors, but it only puts up a button for the Current scene, the Menu. There are two other scenes in the Build Settings, but they don't show up, so I can't test if t$$anonymous$$s is working. The Debug shows 1 Scene. Any idea why t$$anonymous$$s wouldn't show me how many scenes there are?

The documentation on t$$anonymous$$s is not complete, so I have nowhere else to turn.

Until they give us a GetScenesInBuildSettings(), you can get a list of build settings scenes using EditorBuildSettings.scenes http://docs.unity3d.com/412/Documentation/ScriptReference/EditorBuildSettings-scenes.html

The catch is it's UnityEditor only. But you can create a custom inspector that saves it to a list in some Monobehaviour.

They are ordered, so remove the non-enabled scenes and you can get the buildIndex. To get the scene name, use Path.GetFileNameWithoutExtension(scenePathFromBuildSettings);

Well, this worked. I've got a nice menu interface that gathers the list of scenes in editor mode, and then makes buttons that allow you to select the level. Works on the cell phone. NOW I have a cardboard demo! Thanks!

I had the same problem and with the help of t$$anonymous$$s post I could fix it. I t$$anonymous$$nk t$$anonymous$$s code could help those who want to solve the same problem.

Thanks! :)

 using UnityEditor;
 using System.IO;
 
     EditorBuildSettingsScene[] allScenes = EditorBuildSettings.scenes;
     Debug.Log ("All Scenes : Length : "+allScenes.Length);
     string path;
     for (int i = 0; i < allScenes.Length; i++) {
         Debug.Log ("All Path : Scene : "+allScenes[i].path);
         path = Path.GetFileNameWithoutExtension (allScenes[i].path);
         Debug.Log ("Clear Path : Scene : "+path);
     }

Fair warning for anyone who's looking to export their game in the future: This code is not for you!

According to the current best answer from FlyingHighUp EditorBuildSettings.scenes only works in the Editor, therefore preventing you from building any projects you use this type of code in.

The confusing t$$anonymous$$ng is, there is a EditorSceneManager and a SceneManager. The SceneManager works also in the Editor as well.

T$$anonymous$$s example fills a scenes array with all scenes in the $$anonymous$$erarchy.

 using UnityEngine.SceneManagement;    
 Scene[] Scenes = new Scene[SceneManager.sceneCount];
     for (int i = 0; i < SceneManager.sceneCount; i++) {
         Scenes[i] = SceneManager.GetSceneAt(i);
         Debug.Log(Scenes[i].name);
     }
