重载输出运算符未按预期工作

Question

我正在尝试重载 std::cout << player2; 我得到“0x7f60b0100”作为输出。

“player2”是一个 Actor*，所以我不确定发生了什么。

class Actor {

private:
    string type;
protected:
    int health;
    int damage;
    vector<MoveType> moves;

public:
    Actor(string type, int health): type{ type }, health{ health }{damage=0;}
    virtual void Hit(int damage){health = health-damage;}
    virtual void Heal(int amount){health=+amount;}
    const vector<MoveType>& GetMoves() const {return moves;}

    bool IsDead() { return health <= 0; }

    friend ostream& operator<<(ostream& out, const Actor& actor){
        return (out << "DAMAGE DONE: " << actor.damage << "HEALTH: "<< actor.health);
    }
};

Answer 1

正如你所说，它是一个指向 Actor 实例的指针，所以这就是你打印出来的，这个指针的值。

你需要取消引用指针：

std::cout << *player2;
