Godot 4.3

Question

So these 8 buttons are tied to some boolean values I keep on another script. if those values are false I want them to be gray. if they are true I want them to be red. Everytime you press the button it inverts whatever that value was.

For some reason the only style that doesnt work is the grey-non-pressed one. I dont know if its a problem with godot not drawing the button until i click it or something else. Here’s the whole script. Thanks in advance:

extends Control

@onready var grid_container:GridContainer = $Panel/VBoxContainer/MarginContainer/GridContainer

const GREY = preload("res://styles/grey.tres")
const GREY_PRESS = preload("res://styles/grey_press.tres")
const RED = preload("res://styles/red.tres")
const RED_PRESS = preload("res://styles/red_press.tres")

var buttons:Array
var current_char = 0

func _ready() -> void:
  visible = false
  buttons = grid_container.get_children()

  for i in range(min(8, buttons.size())):
    buttons[i].pressed.connect(func(): on_button_pressed(i))

    update_buttons()

func _process(delta: float) -> void:
  if Input.is_action_just_pressed("open_chars"):
    visible = !visible
    update_buttons()
  if Input.is_action_just_pressed("left"):
    current_char -= 1
    if current_char < 0: current_char = 33
    update_buttons()
  if Input.is_action_just_pressed("right"):
    current_char += 1
    if current_char > 33: current_char = 0
    update_buttons()

func update_buttons():
  for i in 8:
    var button : Button = buttons[i]

    var normal_style = RED if Main.chars[current_char].bosses[i] else GREY
    var pressed_style = RED_PRESS if Main.chars[current_char].bosses[i] else GREY_PRESS

    button.add_theme_stylebox_override("normal", normal_style.duplicate())
    button.add_theme_stylebox_override("hover", normal_style.duplicate())
    button.add_theme_stylebox_override("pressed", pressed_style.duplicate())
    button.add_theme_stylebox_override("hover_pressed", pressed_style.duplicate())

    #button.flat = !Main.chars[current_char].bosses[i]

  $Panel/VBoxContainer/MarginContainer2/Label.text = Main.chars[current_char].name
  Saver._save()

func on_button_pressed(button_index: int):
  Main.change(current_char, button_index)
  update_buttons()
