战斗游戏- c++，给定一个刷出职业，我如何每回合刷出更强的敌人
Combat Game - C++, Given a Spawner Class, How can I spawn stronger enemy every round
我在OOP作业中有一个问题。我必须编码一场1v1的战斗。
这是一款生存游戏，玩家与敌人持续战斗，直到玩家死亡。玩家在前进过程中变得更强大。敌人也变得越来越强大。
我已经创建了两个类，单位和产卵。我们不能使用继承和多态性。我们只能使用类的简单定义。
我的问题是，我不能想到一个简单的方法，使类刷出一个更强大的敌人每一轮。
我想过重载单元的构造函数，但我在操作时遇到了麻烦。
有人能帮忙吗?
这是我的单元头文件(Unit.h):
#pragma once
#include <string>
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
// Class Types
const string CLASS_WARRIOR = "Warrior" ;
const string CLASS_ASSASSIN = "Assassin";
const string CLASS_MAGE = "Mage" ;
// Class Choices
const int CHOICE_WARRIOR = 1;
const int CHOICE_ASSASSIN = 2;
const int CHOICE_MAGE = 3;
// Multipliers
const double MULTIPLIER_DAMAGE = 0.50f;
const double MULTIPLER_HEAL = 0.30f;
// Advantage
const bool ADVANTAGE = true;
// Win Bonus
const int BONUS_THREE = 3;
const int BONUS_FIVE = 5;
// Minimum and maximum values
const int HIT_RATE_MAX = 80;
const int HIT_RATE_MIN = 20;
const int DAMAGE_MIN = 1;
// Hit or miss
const bool ATTACK_HIT = true;
const bool ATTACK_MISS = false;
class Unit
{
public:
// Constructors

// Getters and setters
string getName();
string getClass();
int getHp();
int getMaxHp();
int getPower();
int getVitality();
int getAgility();
int getDexterity();
int getDamage();
int getHeal();
int getBonusDamage();
bool getFirstToAttack();
bool getHit();
void setClassStats(const int classChoice);
// Primary Actions
void attack(Unit* target);
// Secondary Actions
void check(const Unit* target); // Inspects the enemy
void lvlUp(); // Grants this Unit Bonus Stats on Victory

}
为Unit类添加一个"等级"，并使用该等级来增加单位的属性(例如，等级2可能意味着属性乘以1.5或诸如此类)。将level作为参数传递给构造函数，类似于units类。
你需要让你的刷出器知道它已经刷出了多少敌人:
// this belongs into your class definition, it should start at zero
int mCurrentSpawn;
因此在构造函数中将其设置为0:
Spawner::Spawner()
{
mCurrentSpawn = 0;
}
然后当你刷出敌人时引用它:
void Spawner::spawn(Unit *& unit)
{
mRandomClass = rand() % 3 + 1;
unit = new Unit("Enemy", mRandomClass);
mUnit = unit;
mCurrentSpawn++;
int levelUps = mCurrentSpawn - 1;
while(levelUps > 0)
{
mUnit->lvlUp();
levelUps--;
}
}
