## Variables and Functions
##
## This block of code contains all of the variables and functions required to
## get the screens to work.

init -2 python:
    #### Sofie(my MC)'s health
    ## Change this to whatever your character is named.
    sofie_health = 90
    #### Her sanity
    sofie_sanity = 100
    #### The date in the game
    ## Made an empty string at the beginning because you
    ## haven't yet started the game, and so you're not anywhere.
    date_ref = ""
    #### The time reference in the game
    ## For this, I usually use 3-hour chunks, unless I need
    ## something a bit more specific for a certain part.
    time_ref = ""
    #### Your current location in the game
    loc_ref = ""
    #### The curent page of the journal
    current_journal_page = 0
    #### The number of journal pages which can be accessed
    ## You'll want to increment this variable as you go, every time
    ## you hit a point where the player should have access to the next
    ## journal entry, which are pre-defined below.  As this is set to 3,
    ## you can access all the pages I have put into the list below.
    ######## WARNING! ########
    ## If you make this higher than the number of journal pages defined
    ## in the list below, it'll spit you out an error when you try to
    ## access a part of the list which doesn't exist.  If it's giving you
    ## a problem of it being outside the bounds of the array, that's what
    ## you did wrong.
    unlocked_journal_pages = 3
    #### The contents of the journal pages
    ## This is a list of the contents of the journal pages.  The first
    ## item in the list, in this case "X", is in position 0, so your
    ## current journal page, which is set to zero, points to this location.
    ## For the sake of easy programming, define all of your journal pages
    ## before-hand.  Otherwise, you have to deal with inserting them and
    ## nonesense like that, which is sort of painful until you get the
    ## hang of doing it.
    journal_entries = list([
        "X",
        "Y",
        "Z"
        ])
   
    #### The increment function
    ## This is what you put after your "action" keyword
    class incrementJournal():
        ## This defines what happens when the class is called
        ## (as in, when you click the button)
        def __call__(self):
            ## Gotta use the "global" keyword to use any variable
            ## outside your function, as it's a quirk of Python
            global current_journal_page
            ## Increment the counter variable which keeps track of
            ## which journal page is currently active
            current_journal_page += 1
            ## Restart the interaction to refresh your screen
            renpy.restart_interaction()
       
    #### The decrement function
    ## Exactly the same as above, only you decrement the
    ## counter variable, instead of incrementing it.
    class decrementJournal():
        def __call__(self):
            global current_journal_page
            current_journal_page -= 1
            renpy.restart_interaction()
       
    #### The void function
    ## A void function that I like to use to block out buttons
    def void():
        ## Do something that won't affect the rest of the game
        DummyVariable = 0
