[solved] Python Function

[Kaen]

I'm trying to make a python function that changes the value of a variable:

Code: Select all

# The game starts here.
label start:

python:
    num = 1

    def add_num():
        num += 1
        return num

label testing:
    $ newnum = add_num()
    "[newnum]"

But I'm receiving an error:

Code: Select all

UnboundLocalError: local variable 'num' referenced before assignment

What should I do so I don't need to write $ num += 1 everytime I want this to happen through my game? I wish I could use a function to do this to me...

You need to treat your "num" variable as global one

Code: Select all

python:
    num = 1

    def add_num():
        global num
        num += 1
        return num
