route that unlocks when all of the other routes are complete

[Seiza]

Hello, I'm new to ren'py and i've been meaning to ask,
How do you create a route that unlocks only when all of the other routes have been played?
(i.e. There are four routes, route a, b,c, and d, and route d can only be played once the player has completed routes a,b, and c)
and if possible, kindly specify the code itself? (My only programming experience involves Javascript and HTML+CSS web development so i'm not really good when it comes to the python based ren'py engine...
Thank you in advance...

Code: Select all

if all([a, b, c]):
    # show route d option.

a, b and c can be any object that returns True when that route is in an unlocked state.

I can elaborate on xela's proposal:

Code: Select all

label start:
    $ a, b, c, d = False, False, False, False
    $ show_d = False

label end_route_a:
    $ a = True
label end_route_b:
    $ b = True
label end_route_c:
    $ c = True

# checking endings:
    if all([a, b, c]):
        $ show_d = True

You need to put this pieces of code in the correct place, not all together as in my example.

Thank you so much! After trying the code and putting the pieces in the right place i was finally able to make the route unlock!
