不能讓子類正常工作

Question

我製作了一個簡單的基於文本的格鬥遊戲，並且我有很多麻煩讓我的子類工作。

了許多錯誤的

即時得到最持續性是「行定義我們的‘小矮人’不符的任何聲明，‘矮人’

#include <iostream> 
using namespace std; 

class Poke{ 
protected: 
    string race; 
    int health, damage, shield; 
public: 
    Poke(); 
    Poke(int health, int damage, int shield); 
    virtual int attack(Poke*); 
    virtual int defend(Poke*); 
    virtual int getHealth(); 
}; 

這是不同的比賽之一sublcasses，有2個不同級別的攻擊/健康/屏蔽

// Dwarf: High health, Low attack, High defense 
class Dwarf: public Poke { 
public: 
    string race = "Dwarf"; 
    int attack(Poke*); 
    int defend(Poke*); 
    int getHealth(); 

}; 

的.cpp V

//DWARF 
Dwarf::Dwarf(int health, int damage, int shield) { 
    this->health = 100; 
    this->damage = 50; 
    this->shield = 75; 
}; 

//attack 
int Poke:: attack(Poke*){ 
    if (shield > (damage + rand() % 75)){ 
     cout << "Direct Hit! you did" << (health - damage) << "points of damage"; 
    } 
    else {std::cout << "MISS!"<<; 
    } 
    return 0; 
}; 

int Poke:: attack(Poke*){ 
    Enemy this->damage ; 
}; 

我使用的是球員類的人打，將使用「戳」

class Player{ 
    int wins, defeats, currentHealth; 
    string name; 
    Poke race; 
    bool subscribed; 
public: 
    Player(int wins, int defeats, int currentHealth); 
    int addWins(); 
    int addDefeats(); 
    int getWins(); 
    int getDefeats(); 
    int getHealth(); 


}; 

的.cpp V

//getHealth 
int Player::getHealth(){ 
    return this->currentHealth; 
}; 

，並和計算機對手「敵」類遊戲：

class Enemy{ 
    int eHealth; 
    Poke eRace; 
public: 
    Enemy (int eHealth, Poke eRace); 
    int getEHealth; 
}; 

的.cpp V

int Enemy:: getEHealth(){ 
    return this->eHealth; 
}; 

任何幫助將不勝感激！

Answer 1

構造函數不被繼承。您必須聲明符合您定義的Dwarf構造函數。

我想你也有麻煩，這樣的：

string race = "Dwarf"; 

您不能初始化類成員的方式。它必須在構造函數中初始化。

編輯：

你似乎不明白我的意思是什麼聲明。更改Dwarf類的聲明看起來是這樣的：

// Dwarf: High health, Low attack, High defense 
class Dwarf: public Poke { 
public: 
    string race; 

    Dwarf(int health, int damage, int shield); // <-- constructor declaration 
    int attack(Poke*); 
    int defend(Poke*); 
    int getHealth(); 

}; 

編輯2：

你Dwarf構造也應該調用Poke構造，像這樣：

Dwarf::Dwarf(int health, int damage, int shield) : 
    Poke(health, damage, shield), 
    race("Dwarf") 
{ 
    // Nothing needed here. 
};
