Pygame - Получение черного экрана

Question

У меня проблема с моим кодом. Когда я запускаю, он не выдает никаких ошибок, а только открывает черный экран. Я новичок в кодировании BTW. Наконец, что касается карт, я не создал и не нашел ни одной карты в Интернете, поэтому я поместил файлы шаблонов '.png', чтобы проверить, работает ли мой код. Вот файлы: https://drive.google.com/drive/folders/1t6EAG7cWSTDItHJnqNeHeJrnbT-2E_8B?usp=sharing

Ваш отступ неправильный, код отрисовки должен быть в цикле.

def game_loop():
    gameExit = False

    while not gameExit:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                quitgame()
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_w:
                    changeY = -10
                    down = False
                    left = False
                    right = False
                    up = True
                if event.key == pygame.K_a:
                    changeX = -10
                    down = False
                    left = True
                    right = False
                    up = False
                if event.key == pygame.K_s:
                    changeY = 10
                    down = True
                    left = False
                    right = False
                    up = False
                if event.key == pygame.K_d:
                    changeX = 10
                    down = False
                    left = False
                    right = True
                    up = False

                    char = lookUp
                    down = False
                    left = False
                    right = False
                    up = False
                if event.key == pygame.K_a:
                    changeX = 0
                    char = lookLeft
                    down = False
                    left = False
                    right = False
                    up = False
                if event.key == pygame.K_s:
                    changeY = 0
                    char = lookDown
                    down = False
                    left = False
                    right = False
                    up = False
                if event.key == pygame.K_d:
                    changeX = 0
                    char = lookRight
                    down = False
                    left = False
                    right = False
                    up = False


            map()
            character(0, 0, 400, 300)
            pygame.display.flip()
            clock.tick(12)

также используйте display.flip()
