Python: заготовка игры с использованием pygame

Добавить комментарий

Пример программы на Python с использованием библиотеки pygame. Создаётся объект из рисунка, прописаны события на нажатие и отпускание клавиш со стрелками. В цикл добавлена задержка sleep.

Код:

import sys, pygame
pygame.init()

size = width, height = 640, 480
speed = [0, 0]
black = 0, 0, 0

screen = pygame.display.set_mode(size)

ball = pygame.image.load("hero.gif")
ballrect = ball.get_rect()

while 1:
    for event in pygame.event.get():
        if event.type == pygame.QUIT: sys.exit()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_UP:
