This may be hard to understand because this is hard to explain
I have 6 scenes and one 'start' scene.
The start scene will be where my scene manager is.
So I want function where when the player clicks on the the start scene it goes to a random scene (from the 6 scenes) and then it goes to start. Then when you click again it goes to random scene, but this time these random scenes will be between the remaining 5 (excluding the scene the player just went on) and then it goes back to start. Then it goes to a random scene time, this time these random scene will be between the remaining 4. And so one.
I already know how to go a random scene and back but I don't know how to do the remaining
