在学习完类的相关知识后，作者建议自己试着用类制作游戏，于是我就按照他的方法制作了一个和他的游戏类似的小游戏。
作者制作游戏的流程大致是：
The process is as follows:
- Write or draw about the problem.
- Extract key concepts from #1 and research them.
- Create a class hierarchy and object map for the concepts.
- Code the classes and a test to run them.
- Repeat and refine.
总的来说就是提取提到的问题的关键词，然后解决对应的问题。
作者的这句话说的很好：
make a list of all the nouns and verbs in your writing
名词用来写类名，动词用函数解决。这样思路就比较清晰了，解决问题思路清晰，有迹可循。
1、问题描述：游戏（ 寻宝游戏），制作大致五个地图，每一个地图设置不同的闯关难题，让玩家参与互动，进行闯关；每通过一个关卡，就会得到对应的奖励，和对应的宝藏之玉碎片。五个地图全部闯关成功，集齐五个碎片，就能成功获得宝物，游戏结束；每个地图闯关失败，会有对应的惩罚甚至是造成闯关失败！
2、关键词提取：地图名字；互动内容；惩罚机制；闯关成功
3、我设置六个地图的名字：
ELFRoom;
TigerRoom;
BabyRoom;
EinsteinRoom;
DragonRoom;
ReadingRoom；
DeathRoom.
互动内容：自己在每个关卡设置对应的问题或者任务，答对或者完成就可通过本关卡。
惩罚：重新进入关卡，或者直接宣告死亡（闯关失败）！
争取把前边的内容都尽可能用上，复习一下，熟能生巧。
| 地图名字 | 互动内容 |
|---|---|
| ELFRoom | 引入地图 |
| TigerRoom | 打架or挑逗 打败老虎，得到碎片 |
| BabyRoom | 救下Baby，得到碎片 |
| EinsteinRoom | 智力问答，得到碎片 |
| DragonRoom | 帮助王子救下公主，得到碎片 |
| ReadingRoom | 猜中文件中的内容，得到最后一个碎片 |
| DeathRoom | 挑战失败 |
4、完成这部分工作后，进行对事件进行类处理。
- 设置场景（Scene）为父类；
ELFRoom;TigerRoom;BabyRoom;EinsteinRoom;DragonRoom;ReadingRoom；DeathRoomf
都是作为它的子类存在。
- 设置地图（Map）为父类，使进入地图有迹可循；
- 设置引擎（Engine）为父类，使其能正常切换场景
确定类的关系后，进一步确定每个类应该有的函数：
Scene（） 应该包括进入地图函数；
Map（）应该包括初始化函数，切换地图函数，打开地图函数；
Engine（）应该包括初始化函数，运行函数。
5、接下来就是书写游戏框架，进行初步调试:
class Engine(object):
def __init__(self):
pass
def play(self):
pass
class Scene(object):
def enter(self):
pass
class Map(object):
def __init__(self):
pass
def next_scene(slef):
pass
def opening_scene(self):
pass
class ElfRoom(Scene):
def enter(self):
pass
class TigerRoom(Scene):
def enter(self):
pass
class BabyRoom(Scene):
def enter(self):
pass
class EinsteinRoom(Scene):
def enter(self):
pass
class DragonRoom(Scene):
def enter(self):
pass
class ReadingRoom(Scene):
def enter(self):
pass
class Death(Scene):
def enter(self):
pass
运行结果是：
PS C:\Users\15222> cd lpthw
PS C:\Users\15222\lpthw> python debug.py
PS C:\Users\15222\lpthw>
说明框架书写正确，没有错误。
6、接下来，对框架添加对应的函数（自己想办法添加各种考验，每个关卡尽量形式多样，并且顺便当作复习前边学习的知识），实现寻宝功能。这里我继续运用书中老师的游戏运行框架。
这是我完善后的代码：

script, filename = argv
global count

self.scene_map = scene_map

current_scene = self.scene_map.next_scene(next_scene_name) #
class Scene(object):
def enter(self):
print "This scene is not yet configured. Subclass it and implement enter()." #this sentence is not clear
exit(1)
class Death(Scene):
mocks = [
"You died. You kinda suck at this.",
"Your mom would be proud...if she were smarter.",
