总结
- 测试了两个修改接口
task3
说明
- 进行填补和进一步的改进的基础建立在需要从宏观上了解整个项目的构成和逻辑关系，基本思路是通过
.h
- 本来想进行汉化工作，但由于我的测试平台是在macOS，等宽字体的问题和win不能很好地适配
- 在基本的代码填补后的测试中发现，游戏存在部分平衡性问题和bug。在此基础上进行了如下平衡性修改:
- 增加了单次特殊攻击魔力值消耗设定的接口
- 增加每次玩家和enemy操作后魔力值自动回复的功能(enemy恢复能力为玩家的一半)
- 删除了AI生命小于百分之五十情况下无法发动特殊攻击的情况
- 修复了enemy发动特殊攻击条件中的概率错误的bug，并调整为60%
- 改善了enemy的AI，能在等待一回合的自动恢复法力和使用法力药水之间平衡
- 调整玩家每次升级后的生命、法力上限提升和速度提升幅度
- 增加了每次玩家升级后血量和法力值部分恢复的功能
- 调整AI使用物品的逻辑，防止击败enemy后大概率无法获得奖励物品

运行结果
- 请自行build测试或直接下载打包文件
macOS环境需将main.cpp中所有cls替换为clear
- 依旧是对于基类与派生类的逻辑关系需要厘清
