壁球v1.3 操控型

elif event.type == pygame.KEYDOWN:            if event.key == pygame.K_LEFT:              	#。。。            elif event.key == pygame.K_RIGHT:               	#。。。            elif event.key == pygame.K_UP:                #。。。            elif event.key == pygame.K_DOWN:                #。。。

新增了键盘事件

pygame.event.KEYDOWN #键盘按下事件pygame.event.KEYUP #键盘释放事件

KEYDOWN：返回event.unicode，即按键的unicode码，event.key 按键的常量名称，event.mod 修饰符的组合值 ，该unicode码与平台有关
