So I am currently making a snake game similar to Slither.io, but much simpler, you command the snake with WASD keys. But I have a problem with the gameOver() function that runs me into an error when I die. Can anyone help me?
import pygame, sys
from pygame.locals import *
class Snake():
def __init__(self):
pygame.init()
self.fpsClock = pygame.time.Clock()
self.playSurface = pygame.display.set_mode((620, 480))

self.snakeSegments = [[100, 100],[80, 100],[60, 100]]
self.foodPosition = [300, 300]
self.food = 1
self.direction = 'right'
self.changeDirection = self.direction
def gameOver(self):
self.gameOverFont = pygame.font.SysFont('san-serif', 72)
self.gameOverSurf = self.gameOVerFont.render('Game Over', True, self.greyColor)
self.playSurface.blit(self.gameOverSurf, [200,10])
pygame.display.flip()
time.sleep(5)
pygame.quit()
sys.exit()
def keyPressEvent(self, event):
if event.key == K_RIGHT or event.key == K_d:
self.changeDirection = 'right'

if self.foodPosition not in self.snakeSegments:
break
self.food = 1
self.playSurface.fill(self.blackColor)
for position in snakeSegments:
pygame.draw.rect(playSurface, whiteColor, Rect(position[0], position[1], 20, 20))
pygame.draw.rect(playSurface, self.redColor, Rect(foodPosition[0], foodPosition[1], 20, 20))
