【经典】C++&RPG对战游戏
博文背景:
还记大二上学期的时候看的这个C++&RPG游戏(博主大一下学期自学的php,涵盖oop内容),一个外校的同学他们大一学的C++,大二初期C++实训要求做一个程序填空,就是这个 RPG 对战游戏,有几处空需要填上,问我可以不,我就信誓旦旦的说OK,最后“万般无奈多方考究”才给将程序补充完整。最近在做毕业设计,用到C++&QT oop部分,重新温习了下C++ oop,就想起来大二的时候还“捣鼓”过这么个游戏,现重新看了下,进行整理总结,写下该博文。
--------------------华丽的分割线,开始正题-----------------
本RPG游戏介绍:
用户创建一个玩家,与AI进行PK,PK中,可以普通攻击(随机暴击、躲闪)、技能攻击、加血、加蓝。本游戏中指定了5个对手,任务失败或者打败所有对手游戏结束。
代码架构:
mian.cpp:控制游戏流程.
container.h container.cpp:物品类.
player.h player.cpp:角色类.
swordsman.h swordsman.cpp:剑士角色.
archer.h archer.cpp:弓箭手角色.
mage.h mage.cpp:魔法师角色.
每个角色都需要物品,每个角色都继承与角色类。
全部代码如下:
