我构建子类对象的方式有什么问题？

Question

这是我的子类：

class BackGround :public Object{
public:
BackGround(int y){
    character.Load(_T("wallpaper.png"));
    x = 0;
    this->y = y;
    direct = 0;
    width = 1200;
    height = 375;
}
};

我的基类：

class Object{
public:
CImage character;     
int x;             
int y;
int direct;       
int speed;
int width;      
int height;
int Xcenter;
int Ycenter;

Object(){}

void draw(HDC hDC){
    character.Draw(hDC, x, y, width, height, 0, direct*height,width, height);
}
};

当我创建BackGround类的对象时，        BackGround Bg1(0); BackGround Bg2(-WINDOW_HEIGHT);

出现错误：
