New main menu when a variable is set to True?

[WanderLustWolfe]

I'm currently making a visual novel that has around 14 completely different routes, and I want the main menu to change according to which route the player is going down. I've only been using renpy for about a year now, so I don't quite understand the super complicated code, but if I have to use it I will.

Code: Select all

# script.rpy:
label start:
     "Changing the background in direct proportion to the ending."
     menu:
         "Firstday.":
             $ persistent.ending = "first"
         "Second.":
             $ persistent.ending = "second"
         "Return main background.":
             $ persistent.ending = "main"
     return

# screens.rpy:
screen main_menu:
     # This replaces other menus.
     tag menu
     # The background of the main menu.
     window:
         style "mm_root"
         if persistent.ending == None:
             $ persistent.ending = "main"
         background ("images / mm-% s.jpg"% (persistent.ending))
         # etc.
