(pygame)sample1.py

在窗口显示一个会动的bmp图片，运行程序需要准备一个sample1.bmp文件，当是入门程序好啦。
import sys, pygame
pygame.init()
size = width, height = 320, 240
speed = [2, 2]
black = 0, 0, 0
screen = pygame.display.set_mode(size)
ball = pygame.image.load("sample1.bmp")
ballrect = ball.get_rect()
while 1:
   for event in pygame.event.get():
      if event.type == pygame.QUIT:
         sys.exit()
      ballrect = ballrect.move(speed)
      if ballrect.left  width:
         speed[0] = -speed[0]
      if ballrect.top  height:
         speed[1] = -speed[1]
      screen.fill(black)
      screen.blit(ball, ballrect)
      pygame.display.flip()
#     import time
#     time.sleep(0.01)
