Changing build index of scene

Hello, I don`t know any way to do this. I understand your idea, but the only way to change the build index is by changing this in the build settings. You could create a method which would load a scene from an "ID". The idea is , that you assign ID`s 101,102... to certain levels.

Let`s say, you get the index of the first level in each category on start and you assign these ID`s to the levels from the index of the first level in each category to the first level in the next category - 1 by index. I hope you understand my idea. Example:

 private int easyIndex;
 private int mediumIndex;
 private int hardIndex;
 
 void Start() {
  easyIndex = //Get first scene of the easy category by name
  mediumIndex = //...
  hardIndex = //...
  //Loop through all the types levels and create either an array or a class with the ID`s and assign the values
 }
 
 //Method to return the scene by it`s ID

Now you can load the scene by its ID. I hope this helped you.

:D

P.S.: If i was unclear in describing my idea, just tell me, I will try to explain it again. :)
