Why isn't the variable updated?

[Ingword]

Hi! Tell me, please, why in this code I do not update the value of $ today?

I set the variables:

Code: Select all

   $ day = 4
   $ week = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
   $ today = week[(day)]

This code put in script.rpy:

Code: Select all

init -1 python:
   def tik():
       global hours
       global day
       hours += 1
       if hours > 23:
           day += 1
           hours = 0
       return

This code put in screen.rpys:

Code: Select all

label info:
   screen home:
       fixed:
           text "[today]" xalign 0.5 yalign 0.10
   call screen home

I found a solution, but now there was another question: why the changed values are not stored in memory?

If you save the game and load, then the day and time values will return to the original, and any conditions are not checked.

Code: Select all

init -1 python:
    
    def clocktick():
        global hours
        global day
        hours += 1
        if hours > 23:
            hours = 0
            day += 1
        return

    day = 4
    hours = 18
    daynames = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
    def weekday():
        return daynames[(day%7)]

Code: Select all

label room:
    scene room
    show bg room
    if day == 5:
        "It's saturday!"
    call home

But... It doesn't work.

Current best practices, especially to ensure the proper functioning of save and rollback is to declare your variable using default. Also you forgot the global declaration in your weekday function.

So:

Code: Select all

default day = 4
default hours = 18
default daynames = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]

init -1 python: 
    def clocktick():
        global hours
        global day
        hours += 1
        if hours > 23:
            hours = 0
            day += 1
        return

    def weekday():
        global daynames
        return daynames[(day%7)]

trooper6, thanks for the answer! In general, everything works as it should, except for one thing: while saving and later loading, the values are reset to the initial ones that were set as default

Except for one case, if there is a code like:

Code: Select all

label my_room:
    scene my_room
    show bg my_room
    if hours == 21:
        #something
    call home

Then while saving and later loading, the value of the variable "hours" 21, even i saving at 23:00...

Now i have:

Code: Select all

default day = 0
default hours = 0
default daynames = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]

init -1 python:

    def clocktick():
        global hours
        global day
        hours += 1
        if hours > 23:
            hours = 0
            day += 1
        return

    def weekday():
        global daynames
        return daynames[(day%7)]


label start:

    $ day = 4
    $ hours = 18
    $ daynames = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]

label my_room:
    scene my_room
    show bg my_room
    if hours == 21:
        "It's 21 o'clock"
    call bar #it's icon's bar

I found a regularity: if my function clocktick() returns True or any other value, then the story starts moving forward and the save work normally.

But what needs to be returned in order to just twist the time ...
