Pick Random but delete from possible list?

[EdibleWare]

Hi everyone, I am working on a Rogue Like-like, I am using INI files do save my pre-made levels, but on the run I want to call then into the game.

Thing is: I don't want the same level to ever happen again. What is the best way to do this?

Thanks a lot!

When you load your game, put all the levels into a list object, one level name per line. Then you can pick a line at random from 0 to total number of lines. Use that to load your random level, then delete the line from your list. Now that level will never be randomly picked from the list object again since it was removed.
