钻石多重继承 C++ 的问题，其中未正确分配新值

问：

我有以下钻石级继承：

       ClapTrap
      /         \
  ScavTrap    FragTrap
     \          /
      DiamondTrap

我将在下面分享我的类，但最终我尝试将 DiamondTrap 的成员变量设置为特定值，有些继承自 ScavTrap，有些继承自 FragTrap。 出于某种原因，即使我专门覆盖了这些值，它似乎仍保留了签名中最后一个继承类的值。

有人可以澄清以下几点：

1. 在本练习中，我是否正确地实现了继承？
2. 为什么当我尝试直接在 DiamondTrap 中设置和打印 ScavTrap：：_energyPoints 时，它会设置并打印 FragTrap _energyPoints值？我检查了它肯定分配了 FragTrap：：_energyPoints 而不是 ScavTrap：：_energyPoints

 class ClapTrap {
protected:
    std::string _name;
    int         _hitPoints;  // constructor sets to 10
    int         _energyPoints; // constructor sets to 10
    int         _attackDamage; // // constructor sets to 0
    ClapTrap(void);

public:
    ClapTrap(const std::string name);
    ClapTrap(const ClapTrap& toCopy);
    ClapTrap& operator=(const ClapTrap& src);
    ~ClapTrap(void);

    void attack(const std::string& target);
    void takeDamage(unsigned int amount);
    void beRepaired(unsigned int amount);

    const std::string   getName(void) const;
    int                 getHitPoints(void) const;
    int                 getEnergyPoints(void) const;
    int                 getAttackDamage(void) const;

    void    setName(std::string name) ;
    void    setHitPoints(int hp) ;
    void    setEnergyPoints(int ep) ;
    void    setAttackDamage(int ad) ;
};

class FragTrap : virtual public ClapTrap {
// constructor sets inherited hitPoints = 100,
// energyPoints = 100 , attackDamage = 30
public:
    FragTrap(const std::string name);
    FragTrap(const FragTrap& toCopy);
    FragTrap& operator=(const FragTrap& src);
    ~FragTrap(void);

    void    highFiveGuys() const;

};

class ScavTrap : virtual public ClapTrap {
// constructor sets inherited hitPoints = 10,
// energyPoints = 50 , attackDamage = 20

public:
    ScavTrap(const std::string name);
    ScavTrap(const ScavTrap& toCopy);
    ScavTrap& operator=(const ScavTrap& src);
    ~ScavTrap(void);

    void    guardGate() const;

};

class DiamondTrap : public ScavTrap, public FragTrap {
private:
    std::string _name;
public:
    DiamondTrap(const std::string name);
    // DiamondTrap(const DiamondTrap& toCopy);
    // DiamondTrap& operator=(const DiamondTrap& src);
    ~DiamondTrap(void);
};
DiamondTrap::DiamondTrap(const std::string name) : ClapTrap(name + "_clap_name"),  ScavTrap(name), FragTrap(name){
    std::cout << "DiamondTrap constructor called" << std::endl;
    this->_name = ClapTrap::_name;
    this->_hitPoints = FragTrap::_hitPoints;
    this->_energyPoints = ScavTrap::_energyPoints;
    this->_attackDamage = FragTrap::_attackDamage;
    std::cout << this->getHitPoints() << std::endl; // output 100
    std::cout << this->getEnergyPoints() << std::endl; // output 100 should be 50
    std::cout << this->getAttackDamage() << std::endl; // output 30
    std::cout << this->_hitPoints << std::endl; // output 100
    std::cout << this->_energyPoints << std::endl; // output 100 should be 50
    std::cout << this->_attackDamage << std::endl; // output 30
    std::cout << ScavTrap::_energyPoints << std::endl; // output 100 should be 50
} 

谢谢
