这篇文章主要介绍了Python实现的弹球小游戏,可实现类似乒乓球游戏的键盘控制底部挡板移动碰撞小球的游戏功能,需要的朋友可以参考下

本文实例讲述了Python实现的弹球小游戏。分享给大家供大家参考，具体如下：

弹球

1. Ball 类

draw负责移动Ball
碰撞检测，反弹，Ball检测Paddle

2.Paddle类

draw负责移动Paddle
碰撞检测，确定能不能继续
监听键盘事件

3.主循环

绘制Ball和Paddle
update
sleep

代码

									from Tkinter import *

									import random

									import time

									class Ball:

									  def __init__(self, canvas, paddle, color):

									    self.canvas = canvas

									    self.paddle = paddle

									tk = Tk()

									tk.title("Game")

									tk.resizable(0, 0)#not resizable
