OS Calendar in Ren'py

[Luxliev]

I know that I can create my own calendar but can I as well ask Ren'py to check my operating system / bios calendar, date?

if sysdata = 1 April:

Hopefully this'll be some help: https://docs.python.org/2/library/calendar.html

[Luxliev]

To do this I think that I need calendar code that is here:
https://hg.python.org/cpython/file/2.7/Lib/calendar.py

If so then how can I import python (.py) code into renpy?

[PyTom]

You should be able to just do:

Code: Select all

init python:
    import calendar

[Luxliev]

Thank you for answer. After importing, calendar date still doesn't seem to be defined. I hoped that it will be complete code but it seems that it isn't or I'm missing something. Can anyone who might be familiar with this code tell me if I'm going in good direction at all?

I wanted to test if I can run anything after checking in this example month of the year:

Code: Select all

I'm sorry, but an uncaught exception occurred.

Calendar code link as above: https://hg.python.org/cpython/file/2.7/Lib/calendar.py

This code is over 700 lines long and is above my understanding of how python works.

Here is documentation of this code as well: https://docs.python.org/2/library/calendar.html

[PyTom]

The problem is almost certainly in your code, rather than the python code.

[Luxliev]

Thank you for answer and checking the code out.

I just made quick code in Ren'py to check if calendar is defined and I still encounter same error. Here it is:

Code: Select all

init python:
    import calendar

image bgwhite = "#fff"
image bgblack = "#000"

define e = Character (("Ema"), color="#FF9966")
define rubwin = Character(("Im window"), color="#FF9966", window_top_margin=200, window_left_margin=200, window_right_margin=200, window_bottom_margin=200)

label start:

    e "whatever"

    if month_name == 3:
        
        scene bgwhite

        e "..."

    e "Lorem Ipsum."

    jump start

Same error:

Code: Select all

I'm sorry, but an uncaught exception occurred.

Ok I checked calendar.py code again and I saw that in lines 8, 9, 10, 621 it wants to import following libraries.

Code: Select all

import sys
import datetime
import locale as _locale
import optparse

I downloaded 2.7.9 version of python from https://www.python.org/downloads/ installed it and I searched for libraries mentioned above.

I found:
locale.py (97 kb)
datetime.h (8.11 kb problem here is that .h is c++ library)
couldn't find sys.py in installed folder
optparse.py (59.7 kb)

any help suggestions or where I can find libraries probably required for calendar.py?

[PyTom]

Okay - what are you actually trying to do?

Simply importing the calendar module won't do anything other than importing the calendar module - it won't set the month_name variable for you. You probably don't want the calendar module - time.localtime() might be your best bet - but I need to know what you're actually trying to do to be able to advise you correctly.

I want to implement system date that will be checked whenever I start game so I could add events that would start/activate on specific real date. Best example April Fools or calendar man from batman game.

Code: Select all

if month_day == 4 and day_name == 1:
    jump aprilfoolscode

[PyTom]

I think the datetime module is what you want here.

Code: Select all

init python:
     import datetime
     today = datetime.date.today()

Code: Select all

if today.month == 4 and today.day == 1:
     jump aprilfoolscode

[Luxliev]

Thank you it works as intended

I had to install 3.4.3 version of python from https://www.python.org/downloads/ to get datetime.py library for some reason there is only c++ datetime lib (.h instead of .py) in 2.7.9 version

For everyone else here is code example (you need to install Python 3.4.3 and copy from install folder to your game folder datetime.py :

Code: Select all

init python:
    import datetime
    today = datetime.date.today()

image bgwhite = "#fff"
image bgblack = "#000"

define e = Character (("Ema"), color="#FF9966")
define rubwin = Character(("Im window"), color="#FF9966", window_top_margin=200, window_left_margin=200, window_right_margin=200, window_bottom_margin=200)

label start:

    e "whatever"

    ##current date
    if today.month == 3 and today.day == 6:
        scene bgwhite
        e "..."
        jump start

    e "Lorem Ipsum."

    jump start

One question though: What happens if game is saved and then reloaded in this example? Does date variable is written and saved from first day game was saved or will it be updated?

Example:

I started my game on 30 march and saved my game.

Next day I loaded game and date is 1 April (day when event should began). What will happen.

What today.month today.day variable number will be? When I start game and data is read from script.rpy today.month and today.day will be saved only once during init phase right? Or am I wrong?

Can I implement this code to some menu.rpy file if there is any so today.month and today.day will be always same as the date I run my game? Or maybe I can use code today = datetime.date.today() outside of init: ?

I hope that you understand what I have in mind.

It will be updated when Ren'Py starts. So if the game is started on March 31 at 2359, the date will remain March 31, even if the clock ticks forwards to April 1.

However, if the player saves, exits Ren'Py, starts Ren'Py back up, and loads, the date will be correct.

It's probably best to just call datetime.date.today() right before checking it, using code like:

Code: Select all

init python:
    import datetime

Code: Select all

$ today = datetime.date.today()
if (today.month == 4) and (today.date == 1):
     # ...

Rather than creating the object in the init block. (The import has to be in an init block for technical reasons, however.)

[Luxliev]

Thanks for all your time explaining everything to me. I saved game yesterday and checked it today. Everything worked as it should. I also found out that I don't have to copy datetime.py lib from python installer it was already integrated in Ren'py which is nice.

Problem solved. Thanks again... I'll be back
