小游戏

制作一个跳跃的小球游戏（Pygame基本使用）

import sys    
import pygame    
pygame.init()     
size = width, height = 640, 480    
screen = pygame.display.set_mode(size)     
color = (0, 0, 0)    
ball = pygame.image.load("ball123.png")    
ballrect = ball.get_rect()  
speed = [1, 1]     
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:    
            sys.exit()
    ballrect = ballrect.move(speed)   
    if ballrect.left < 0 or ballrect.right > width:
        speed[0] = -speed[0]
    if ballrect.top < 0 or ballrect.bottom > height:
        speed[1] = -speed[1]
    screen.fill(color)      
    screen.blit(ball, ballrect)     
    pygame.display.flip()     
pygame.quit()
