小编pdi*_*ley的帖子

我有两个类的问题,每个类需要知道其头文件中的另一个.

Structure.h

#ifndef STRUCTURE_H
#define STRUCTURE_H

#include <vector>
#include "Sprite.h"
#include "Bullet.h"

class Structure: public Sprite{
public:
Structure(const BITMAP bm, const Vec2& pos, const Vec2& vel,
              const RECT boundaries, std::vector<std::vector<bool>> holes);
virtual ~Structure() = 0;

void takeDamage(const Bullet* bullet);
protected:
std::vector<std::vector<bool>> mBulletHoles;
};

#endif

Structure.cpp

#include "Structure.h"

Structure::Structure(const BITMAP bm, const Vec2& pos, const Vec2& vel,
                     const RECT boundaries, std::vector<std::vector<bool>> holes)
    :Sprite(bm, pos, vel, boundaries),
     mBulletHoles(holes)
{}

void Structure::takeDamage(const Bullet* bullet){

}

Sprite::~Sprite(){}

Bullet.h

#ifndef BULLET_H
#define BULLET_H

#include "Animate.h" …
