總結
- 測試了兩個修改接口
task3
說明
- 進行填補和進一步的改進的基礎建立在需要從宏觀上了解整個項目的構成和邏輯關系，基本思路是通過
.h
- 本來想進行漢化工作，但由于我的測試平台是在macOS，等寬字型的問題和win不能很好地适配
- 在基本的代碼填補後的測試中發現，遊戲存在部分平衡性問題和bug。在此基礎上進行了如下平衡性修改:
- 增加了單次特殊攻擊魔力值消耗設定的接口
- 增加每次玩家和enemy操作後魔力值自動回複的功能(enemy恢複能力為玩家的一半)
- 删除了AI生命小于百分之五十情況下無法發動特殊攻擊的情況
- 修複了enemy發動特殊攻擊條件中的機率錯誤的bug，并調整為60%
- 改善了enemy的AI，能在等待一回合的自動恢複法力和使用法力藥水之間平衡
- 調整玩家每次更新後的生命、法力上限提升和速度提升幅度
- 增加了每次玩家更新後血量和法力值部分恢複的功能
- 調整AI使用物品的邏輯，防止擊敗enemy後大機率無法獲得獎勵物品
由于代碼過長，僅展示部分，其餘請右擊下列檔案儲存

運作結果
- 請自行build測試或直接下載下傳打封包件
macOS環境需将main.cpp中所有cls替換為clear
- 依舊是對于基類與派生類的邏輯關系需要厘清
