在學習完類的相關知識後，作者建議自己試着用類製作遊戲，於是我就按照他的方法制作了一個和他的遊戲類似的小遊戲。
作者製作遊戲的流程大致是：
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.
總的來說就是提取提到的問題的關鍵詞，然後解決對應的問題。
作者的這句話說的很好：
make a list of all the nouns and verbs in your writing
名詞用來寫類名，動詞用函數解決。這樣思路就比較清晰了，解決問題思路清晰，有跡可循。
1、問題描述：遊戲（ 尋寶遊戲），製作大致五個地圖，每一個地圖設置不同的闖關難題，讓玩家參與互動，進行闖關；每通過一個關卡，就會得到對應的獎勵，和對應的寶藏之玉碎片。五個地圖全部闖關成功，集齊五個碎片，就能成功獲得寶物，遊戲結束；每個地圖闖關失敗，會有對應的懲罰甚至是造成闖關失敗！
2、關鍵詞提取：地圖名字；互動內容；懲罰機制；闖關成功
3、我設置六個地圖的名字：
ELFRoom;
TigerRoom;
BabyRoom;
EinsteinRoom;
DragonRoom;
ReadingRoom；
DeathRoom.
互動內容：自己在每個關卡設置對應的問題或者任務，答對或者完成就可通過本關卡。
懲罰：重新進入關卡，或者直接宣告死亡（闖關失敗）！
爭取把前邊的內容都儘可能用上，複習一下，熟能生巧。
| 地圖名字 | 互動內容 |
|---|---|
| ELFRoom | 引入地圖 |
| TigerRoom | 打架or挑逗 打敗老虎，得到碎片 |
| BabyRoom | 救下Baby，得到碎片 |
| EinsteinRoom | 智力問答，得到碎片 |
| DragonRoom | 幫助王子救下公主，得到碎片 |
| ReadingRoom | 猜中文件中的內容，得到最後一個碎片 |
| DeathRoom | 挑戰失敗 |
4、完成這部分工作後，進行對事件進行類處理。
- 設置場景（Scene）爲父類；
ELFRoom;TigerRoom;BabyRoom;EinsteinRoom;DragonRoom;ReadingRoom；DeathRoomf
都是作爲它的子類存在。
- 設置地圖（Map）爲父類，使進入地圖有跡可循；
- 設置引擎（Engine）爲父類，使其能正常切換場景
確定類的關係後，進一步確定每個類應該有的函數：
Scene（） 應該包括進入地圖函數；
Map（）應該包括初始化函數，切換地圖函數，打開地圖函數；
Engine（）應該包括初始化函數，運行函數。
5、接下來就是書寫遊戲框架，進行初步調試:
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
運行結果是：
PS C:\Users\15222> cd lpthw
PS C:\Users\15222\lpthw> python debug.py
PS C:\Users\15222\lpthw>
說明框架書寫正確，沒有錯誤。
6、接下來，對框架添加對應的函數（自己想辦法添加各種考驗，每個關卡儘量形式多樣，並且順便當作複習前邊學習的知識），實現尋寶功能。這裏我繼續運用書中老師的遊戲運行框架。
這是我完善後的代碼：
