Exception caught when cycling through a list via a button

[Xenubin]

Hi all!

I'm playing around with some screen language again and testing out a super rough character creation screen.

Currently I have a little screen with a name input box, no issues there thankfully,a nd im trying to add a cycleable section below it for something like pronouns, a title, etc for the character as a text displayable.


here's my code for this!

Code: Select all

default list1 = {
    "1" : "", 
    "2": "", 
    "3": ""
}


default selection_variable = 0

screen charcreate:
    image "images/createbg.png"
    fixed: 
        xpos 650
        ypos 490
        text "{color=#000000}This book belongs to{/color}": 
            size 30
            
        input:
            ypos 65
            xpos 20
            pixel_width(500)
            value VariableInputValue("player_name")
    textbutton ">":
        xpos 650
        ypos 700
        action CycleVariable(list1, values=["1","2","3"], loop=True)
    text "[list1[selection_variable]]":
        xpos 675
        ypos 700

    textbutton "Start":
        xpos 1500
        ypos 1000
        action Jump("continue")
        keysym('K_RETURN', 'K_KP_ENTER')

and then the current error i am getting is:

Code: Select all

I'm sorry, but an uncaught exception occurred.

I currently don't feel that the selection_variable is set up to cycle correctly, but i'm not 100% what I need to be doing here with it

[m_from_space]

Code: Select all

default list1 = {
    "1" : "", 
    "2": "", 
    "3": ""
}

Yours is not a list, it's a dictionary.

Code: Select all

default mylist = ["this", "is", "a", "list"]

[Xenubin]

Code: Select all

default list1 = {
    "1" : "", 
    "2": "", 
    "3": ""
}

Yours is not a list, it's a dictionary.

Code: Select all

default mylist = ["this", "is", "a", "list"]

I did Initially have it set up like that, but was still getting the same error when i pressed the button to cycle through the list, which is why it got changed to that lol

even changing it back i still get the "The '1' global variable does not exist'' exception

[Ocelot]

Code: Select all

default var = 0
define name = "var"

CycleVariable("var", [0, 1]) # Cycles var through 0 and 1
CycleVariable(name, [0, 1]) # Cycles var through 0 and 1

Second comment is not a mistake. list1 ≠ "list1".

[m_from_space]

even changing it back i still get the "The '1' global variable does not exist'' exception

I guess what you're trying to do is something like this:

Code: Select all

default fruitlist = ["Apples", "Bananas", "Cherries"]

screen bazaar():
    default fruit = None
    vbox:
        if fruit is None:
            text "Check out our fruits!"
        else:
            text fruit
        textbutton "Next Fruit" action CycleVariable("fruit", fruitlist)
