C++：在函数中使用当前实例（对象）

Question

C++ 社区大家好！

我是 C++ 的新手，我有这个代码示例：

class Player
{
 public:
  int pdamage;
  int phealth;
 /* ... other data members and some void member functions (getName etc.) */
};

class Ennemy
{
 public:
  int edamage;
  int ehealth;
}; 

**/*here i would like to use current objects parameters for calculation and return to current player instance(current player object) the health value.*/**


int playerHit(this.Player.damage,this.Enemy.ehealth)
{
 ehealth = this.Ennemy.ehealth - this.Player.damage;
 return ehealth;
};

int ennemyHit(this.Player.phealth,this.Enemy.edamage)
{
 phealth = this.Player.phealth - this.Ennemy.edamage ;
 return ehealth;
};

int main()
{
/*....*/

return 0;
}

回到post问题： 如何在函数中使用当前对象参数进行计算？

/*由于我是 Whosebug 和 C++ 的新手，感谢所有建议和批评！ */

Answer 1

在 C++ 中，您可以将调用作为指针或引用传递

int playerHit(const Player& player, const Ennemy& ennemy)
{
     return ennemy.ehealth - player.pdamage;
};

C++ : use current instance (object) in function
