So I have this locket with characters and you need to put the correct combination to open it, i created a list for the characters that will go in each slot, a pointer that points in which location the slot is and an image for each character that will change as the letter changes here is the code:

default leftLetters = ["a", "i", "m", "o", "q"]
default leftPointer = 0
default centerLetters = ["f", "r", "s", "u", "e"]
default centerPointer = 0
default rightLetters = ["x", "c", "d", "t", "v"]
default rightPointer = 0
define leftLetterSelectedImage = "buttons/characters/left_slot_o.png"
define middleLetterSelectedImage = "buttons/characters/middle_slot_u.png"
define rightLetterSelectedImage = "buttons/characters/right_slot_t.png"

Now I have this function that is used to change them, shown bellow:

    def changeDownLeftChar():
        global leftPointer
        global leftLetterSelectedImage
        store.leftPointer = (leftPointer + 1) % len(leftLetters)

        nextLetter = leftLetters[leftPointer]

        leftLetterSelectedImage = f"buttons/characters/left_slot_.{nextLetter}.png"

        print("Ok")
        print(leftPointer)

        renpy.restart_interaction()

    def changeUpLeftChar():
        global leftPointer
        global leftLetterSelectedImage
        leftPointer = (leftPointer - 1) % len(leftLetters)
        store.leftPointer = leftPointer

        nextLetter = leftLetters[leftPointer]

        leftletterimage = Image(f"buttons/characters/left_slot_.{nextLetter}.png")

        print("Ok")
        print(leftPointer)

        renpy.restart_interaction()

And this buttons that triggers the function:

screen cabinet_arrows():
    # Left slot
    imagebutton auto "buttons/up_arrow_%s.png" xpos 0.295 ypos 0.022 focus_mask True at arrows action Function(changeDownLeftChar)
    imagebutton auto "buttons/down_arrow_%s.png" xpos 0.295  ypos 0.61 focus_mask True at arrows action Function(changeUpLeftChar)

The thing is that the print function print variable changed, but when I click another time on the button and trigger the function it resets to normal so if i use the changeDownLeftChar function it will always print 1 instead of 1,2,3,4 and so on, because the variable doesn’t change in Ren’pys context, anybody knows why and how to solve it?

Thanks in advance!
