so im programming a game and it's my first time using classes. I have a class that has different fields for different aspects of a background and objects for the different backgrounds. I have a while loop for the start screen. This works however when I click on play it's suppose to set start to False and stop the loop but when I press it, it gets set to False once and straight back to True which continues the loop. I use print to see what the boolean is at all times.
I difine start = True at the top of the code
import pygame
import sys
pygame.init()
start = True
screen_width = 900
screen_height = 507
center_x = screen_width/2
center_y = screen_height/2
screen = pygame.display.set_mode((screen_width, screen_height))
clock = pygame.time.Clock()
FPS = 100
WHITE = (255,255,255)
bgx = 0
bgx2 = screen_width

while start:
print (start)
for event in pygame.event.get():

pygame.quit()
sys.exit()
main_screen.create_screen()
clock.tick(FPS)
pygame.quit()
sys.exit
enter code here
In your function create_screen() you need to add a line that says global start
to tell the python interpreter that variable was defined in a different scope.
