Question

我需要包含两个类：Maze和Screen在其他类粒子中。我需要它们来实现moveEast操作。迷宫是随机生成的迷宫，屏幕具有我绘制角色的屏幕分辨率。我正在使用opengl和过剩。

ghost.h

#ifndef GHOST_H_
#define GHOST_H_
#include "Particle.h"

namespace RandomMaze {

class Ghost : public particle {
public:
    Ghost();
    virtual ~Ghost();
    void drawGhost();

};

} /* namespace RandomMaze */
#endif /* GHOST_H_ */

ghost.cpp

#include "Ghost.h"
#include "Particle.h"

namespace RandomMaze {

Ghost::Ghost() {
    // TODO Auto-generated constructor stubparticle::particle()

      state=QUIET;
}


Ghost::~Ghost() {
    // TODO Auto-generated destructor stub
}

void Ghost::drawGhost()
{
  glColor3f(1,1,1);
  glBegin(GL_QUADS);
  glVertex2i(x-6,y-6);
  glVertex2i(x+6,y-6);
  glVertex2i(x+6,y+6);
  glVertex2i(x-6,y+6);
  glEnd();
}

} /* namespace RandomMaze */

/** Esta clase genera y gestiona el laberinto del juego. */
class Maze {

        //Atributos publicos
    public:
        int **map;

        void drawMaze(int width, int height);
        bool isPassageOrFood( int x, int y);
        void deleteFood(int x,int y);

};


} /* namespace RandomMaze */

#endif /* MAZE_H_ */

screen.h

#ifndef SCREEN_H_
#define SCREEN_H_

namespace RandomMaze {

class Screen {
    int width;
    int height;
public:
    Screen();
    Screen(int w, int h);
    int getWidth();
    int getHeight();
    virtual ~Screen();
};

} /* namespace RandomMaze */
#endif /* SCREEN_H_ */

particle.h

#include "Maze.h"
#include "Screen.h"

class particle {

protected: 

  int i,j; // Current position in map
  float x,y;   //-- Current position
  float vx,vy; //-- Velocity vector
  int state;

  long time_remaining;

public:

  particle();
  void set_positionScreen(int x,int y);
  void set_positionMap(int i,int j);
  int get_positionMapI();
  int get_positionMapJ();
  void moveEast(Maze m, Screen s);
  void init_movement(int destination_x,int destination_y,int duration);
  void init_movementAlongX(int destination_x,int destination_y,int duration);
  void init_movementAlongY(int destination_x,int destination_y,int duration);
  void integrate(long t);
  int getState();
  void draw();
  virtual ~particle();
};

错误消息是：

    ../Particle.h:44:25: error: ‘Screen’ has not been declared
       void moveEast(Maze m, Screen s);
                         ^
make: *** [Ghost.o] Error 1

我的想法是，我在main.cpp中有这些全局变量，称为m（迷宫），s（屏幕）和p（pacman，它是另一个类）。我需要用以下内容调用moveEast操作：

Maze m;
Screen s;
Pacman p;
p.moveEast(m,s);

另外我把声明部分放在主文件中。

的main.cpp

#include "Maze.h"
#include "Screen.h"
#include "Particle.h"
#include <vector>
#include "Ghost.h"
#include "Pacman.h"

#define ROWS 19
#define COLUMNS 40
#define LEVEL 5

#define WIDTH 600
#define HEIGHT 400

#define WINDOW_X 50
#define WINDOW_Y 50

//THE TIME THAT CHARACTER TAKES FROM ONE "SCREEN UNIT TO ANOTHER". Pacman is slightly faster than ghosts.
#define PACMAN_SPEED 1
#define GHOST_SPEED 1000

//Se puede utilizar para correccion
#define CORRECTION 6

void display();
void keyboard(unsigned char c,int x,int y);
void specialkeyboard(int key,int x,int y);
void idle();
void goNorth();
void goWest();
void goEast();
void goSouth();


using namespace std;
using namespace RandomMaze;


//Definición de variables.

vector<Ghost> playingGhosts;
Maze m;
Screen s(WIDTH, HEIGHT);
Pacman myPacman;
long last_t=0;

int main (int argc, char *argv[]){
...
}

任何想法都会被贬低。

Answer 1

Maze和Screen都在namespace RandomMaze，但particle不在。{/ p>

因此，您需要将particle移动到该命名空间中，这样您就可以在没有任何限定的情况下引用它们，或者在使用它们时需要对这些名称进行限定 - RandomMaze::Maze等。

在另一个班级中使用班级
