Introduction

請各位實作一個簡易的職業系統，需求如下：

程式碼Code

public class Job {
    public string Name { get; }
    public Job(string name) {}
    public virtual void OnLevelUp(Character character){}
    public virtual void OnSelected(Character character){}
}

public class Character {
    public int Level;
    public int MaxHp, MaxMp;
    public int PhyAtk, PhyDef;
    public int MagAtk, MagDef;
}

角色基礎數值

// 基礎等級
int BasicLevel = 1;
// 基礎最大HP            
int BasicMaxHp = 100;
// 基礎最大MP
int BasicMaxMp = 50;
// 基礎物理攻擊
int BasicPhyAtk = 10;
// 基礎物理防禦
int BasicPhyDef = 10;
// 基礎魔法攻擊
int BasicMagAtk = 5;
// 基礎魔法防禦
int BasicMagDef = 5;

職業Job

• 初心者(Novice )
  每級提升
  MaxHp + 10
  MaxMp + 5
  PhyAtk + 1

• 騎士(Knight)
  每級提升
  MaxHp + 25
  MaxMp + 5
  PhyAtk + 5
  PhyDef + 3

• 魔法師(Magician)
  每級提升
  MaxHp + 5
  MaxMp + 30
  MagAtk + 8
  MagDef + 3

規則說明(Rule)

• 最低1等，最高100等，第一級的能力不受補正影響(20等只補正了19個等級)
• 沒特別寫到的表示升級時不會增加
• 職業可以中途切換，切換後會自動補正到該職業在該等級時的能力值
  例如：20等初心者HP是290，轉成劍士則會變為575
• Job.Name必須要是該職業名稱(依表格名稱為主）

備註

*測試檔案會有編譯錯誤，請同學們記得使用繼承來解決這個錯誤

好耶頭香

一開始的Job.OnLevelUp想了好久 才知道是把Test的basic手動輸入進去

做完偷看老師做的覺得自己的code跟醜八怪一樣

[jack81722]

培養好習慣不錯
但也不用太過吹毛求疵
邏輯上看得懂大多不會太在意語法上的整齊（對不完）
命名或結構讓人看得懂更為重要

我希望題目盡量靈活
但有時候會導致你們沒辦法理解應該怎麼做（我自己也容易失誤）
事實上修復問題是需要自己主動判斷
也沒有一定要怎麼做
以測試先行的角度來看
從Test內容（後面要自己寫）判斷需求是一個好習慣

測試截圖

一開始不知道有固定的初始值，我全部填0，測試一直過不了。
然後還沒想到轉職數值可以直接用乘的，還用迴圈去跑，看了解答才去改的，我也是很白癡。

還有不知道是Github還是VS轉碼的問題，我的Job的建構子註解裡面有一行變亂碼。

抱歉，已補上基礎數值

[jack81722]

轉碼的問題是因為我使用visual studio
內建用Big5編碼，而vs code是用UTF8

我的反饋

1. 建議投影片中加入職業的基本數值（我一開始以為基礎數值都是0，直到看到單元測試那邊的基礎數值設定）

回饋:
第一次寫的時候把轉職跟升級寫在一起了
只剩下OnLevelUp方法
OnSelected空著
可是測試跑不過
每個值都差1
看了解答才分開寫
加了Reset

寫完之後雖然都能拿到緣勾勾，但一直覺得沒有寫得很好。（；´д｀）ゞ
看了一下老師的答案後就現自己得太粗暴了，所有要計算用的參數都寫在公式裡面，沒有用常數儲存，角色的數值重置也沒有幫它寫一個函式。感覺之後如果要修改角色的數值或是要維修會比較麻煩，看來還要再多跟老師學學(✿◡‿◡)
