## pygame开发小游戏 ##

**话不多说，直接上例子！**

import pygame,sys
    
    pygame.init()
    icon = pygame.image.load("PYG03-flower.png")
    pygame.display.set_icon(icon)
    size = width,height = 600,400
    speed = [1,-1]
    BLACK = 0,0,0
    screen = pygame.display.set_mode(size,pygame.RESIZABLE)
    pygame.display.set_caption("Pygame壁球")
    ball = pygame.image.load("PYG02-ball.gif")
    ballrect = ball.get_rect()
    fbs = 300
    fclock = pygame.time.Clock()
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    speed[0] = speed[0] if speed[0] == 0 else (abs(speed[0]) - 1) * int(speed[0] / abs(speed[0]))
                elif event.key == pygame.K_RIGHT:
                    speed[0] = speed[0] + 1 if speed[0] > 0 else speed[0] - 1
                elif event.key == pygame.K_UP:
                    speed[1] = speed[1] + 1 if speed[1] > 0 else speed[1] - 1
                elif event.key == pygame.K_DOWN:
                    speed[1] = speed[1] if speed[1] == 0 else (abs(speed[1]) - 1) * int(speed[1] / abs(speed[1]))
                elif event.key == pygame.K.ESCAPE:
                    sys.exit()
            elif event.type == pygame.VIDEORESIZE:
                size = width,height = event.size[0],event.size[1]
                screen = pygame.display.set_mode(size,pygame.RESIZABLE)
        if pygame.display.get_active():
            ballrect = ballrect.move(speed[0], speed[1])
        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(BLACK)
        screen.blit(ball,ballrect)
        pygame.display.update()
        fclock.tick(fbs)

**运行效果：**
