码：

#ifndef GAME_H
#define GAME_H

#include "drawEngine.h"
#include "sprite.h"
#include <iostream>
using namespace std;

class Game
{
public:
    bool run(void);

protected:
    bool getinput(char *c);
    void timerUpdate(void);

private:
    Sprite* player; // this gives me C2143

    double frameCount;
    double startTime;
    double lastTime;

    int posx;
    //int posy;
    DrawEngine drawArea;
};

#endif

我该如何解决？

sprite.h

#ifndef GAME_H
#define GAME_H
#include "drawEngine.h"
#include "game.h"

enum
{
    SPRITE_CLASSID,};
struct vector
{
    float x;
    float y;

};

class Sprite
{
public:


    Sprite(DrawEngine *de,int s_index,float x = 1,float y = 1,int i_lives = 1);
    ~Sprite();
    vector getPosition(void);

    float getX(void);
    float getY(void);

    virtual void addLives(int num = 1);
    int getLives(void);
    bool isAlive(void);

    virtual bool move(float x,float y);

protected:

    DrawEngine *drawArea;
    vector pos;
    int spriteIndex;
    int numLives;
    int classID;
    vector facingDirection;
    void draw(float x,float y);
    void erase(float x,float y);

private:
};
