Python and If Statement

[r_metal]

Hello. I have read Quickstart documentation and i got everything but "Python and If statements". Don't get me wrong, I know what Python is and have been learning it for a while before i discovered Ren'Py but i just don't understand that example and what does "bl_game =" do there. If you please can help me understand how to store the user's choices in variables, and access them again later i would really appreciate that!

Code: Select all

#Python makes it easy to store flags in response to user input. Just initialize the flag at the start of the game:

label start:
    $ bl_game = False
#You can then change the flag in code that is chosen by menus:

label hentai:

    $ bl_game = True

    m "Why it's a game with lots of sex."
    s "You mean, like a boy's love game?"
    s "I've always wanted to make one of those."
    s "I'll get right on it!"

    jump marry
#And check it later:

"And so, we became a visual novel creating team."
"We made games and had a lot of fun making them."

if bl_game:
    "Well, apart from that boy's love game she insisted on making."

"And one day..."

RenPy code is just a higher level language which in the end is parsed and executed as Python code.
A dollar sign tells that rest of the line should be interpreted as raw python code. In your case it is just a simple Python statement, which creates variable bl_game or assigns it new value, if it is already exist.

if bl_game: is a RenPy language statement which works wimilarly to Pytjon one: it checks if bl_game is True and executes next block if t is.
