"NameError: name not defined" when trying to use a user defined function

[Yuzumin]

Here is what I've written

Code: Select all

#rp for K
default rp_k = 0
#rp for P
default rp_p = 0
#rp for S
default rp_s = 0
#rp for Y
default rp_y = 0

python:
    def inc():
        nonlocal [rp_y]
        rp_y += 1
    def dec():
        nonlocal [rp_y]
        rp_y -= 1
label start:

    menu:
        "This should lower rp for Y":
            $ dec()

        "This should increase your rp for Y":
            $ inc()

    "Y's RP for you is now [rp_y]"

Here I'm trying to define the function of inc() to increase the variable rp_y by 1 through the use of a user defined function in a menu choice instead of using
$ rp_y = 1+rp_y
I'm a pretty big beginner in Python but I want to try to learn how to make this quick and efficient since I want many menu choices to either increase or decrease rp_y without having to write a long string.

here I went on Jupyter to test out what i wanted to do (I used the global variable instead of nonlocal but both weren't working in renpy) and it worked fine so i'm not really sure what i'm really doing wrong.

error message:

Code: Select all

I'm sorry, but an uncaught exception occurred.

Nevermind I figured it out after a while and reading through a bunch of the documentation. For anyone else that encounters this the main thing I got wrong was writing python init and instead wrote just python. As for efficiency I should've added an argument in the brackets of the function I was defining so I could easily manipulate how much was added or subtracted from the variable rp_y instead of strictly just 1. I also changed the code inside the defined function from nonlocal to global

Code: Select all

#rp for Y
default rp_y = 0

init python:
    def inc(x):
        global rp_y
        rp_y += x

    def dec(x):
        global rp_y
        rp_y -= x

label start:

    menu:
    
        "This should lower rp for Y":
            $ dec(1)

        "This should increase your rp for Y":
            $ inc(1)

    "Y's RP for you is now [rp_y]"
