Phython 小游戏编写

使用PyGame库编写一个对性能要求不那么高的小游戏是非常高效的

特别是Clock机制用起来很舒服，告别界面刷新的麻烦

clock = pygame.time.Clock()

pygame.display.flip()

clock.tick(tms_sec) # tms_sec=timers in a second

春节放假在家，有时间写了一个打地鼠的小游戏，给小朋友玩玩还是足够了，呵呵

while sw_game:

    if timer>0 and timer%tms_sec==0 and clicked == False: # next round

        # redraw the playgd
        for i in range(1,10,1):
            pygame.draw.rect( playgd, color_bk,blok_list[i-1],0)

        # new rats pos
        seed_n = random.randint(0,8)
        while seed_n==seed_o:
            seed_n = random.randint(0,8)
        
        seed_x = seed_n//3+1
        seed_y = seed_n%3+1
        seed_o = seed_n
        
        # draw the rats(icon)
        rat_x = diff_w*seed_x+blok_w*(seed_x-1)
        rat_y = diff_h*seed_y+blok_h*(seed_y-1)
        playgd.blit( ico_rat, [ rat_x,rat_y] )
        #pygame.display.update()
        pygame.display.flip()
        sniffer = True
        #print('sniffer is on: '+str(timer)+', x='+str(seed_x)+',y='+str(seed_y) )

         #continue
