pygame系列_小球完全弹性碰撞游戏
之前做了一个基于python的tkinter的小球完全碰撞游戏：
今天利用业余时间，写了一个功能要强大一些的小球完全碰撞游戏：
游戏名称：
小球完全弹性碰撞
游戏规则：
1.游戏初始化的时候，有5个不同颜色的小球进行碰撞
2.玩家可以通过在窗口中单击鼠标左键进行增加小球个数
3.玩家可以通过在窗口中单击鼠标右键进行删减小球个数
4.玩家可以通过键盘的方向键：上，右键进行对小球加速
5.玩家可以通过键盘的方向键：下，左键进行对小球减速
6.玩家可以按键盘：f键实现全屏显示
7.玩家可以按键盘：Esc键实现退出全屏操作
8.窗口左下角显示小球个数，右下角显示作者邮箱
先看看图：

10 Ball Perfectly Elastic Collision(BPEC)
11 Rules or Description:
12 1.There are five balls whth different color have elastic collision
13 after the game loaded.
14 2.The player can click the window with the LEFT mouse button
15 and create the new ball,which with the different color,but
16 sometimes maybe like other balls.
17 3.The player can click teh window with RIGHT mouse button
18 and minus a few balls.
19 4.You can change all ball speed by pressing the UP and DOWN
20 the keyboard direction key.
21 5.Also you can change the background music by pressing the LEFT
22 and RIGHT the keyboard direction key(volume:0-10).
23 6.Maybe you want to full screen view,By pressing the F key
24 and ESC key switch.
25 7.Ball number,the speed,the volume,author E-mail is written
26 in the status bar at the bottom.
