这里是我的子类:构建子类对象的方式有什么问题?
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);
}
};
当我创建类的背景对象, BackGround Bg1(0); BackGround Bg2(-WINDOW_HEIGHT);
有来的错误:

“出现错误”不是很有用的信息。请发布确切的错误。 (使用复制和粘贴。) – molbdnilo
对不起,我的错。 – Rachel
从输出窗口中复制消息,而不是从错误列表窗口中复制消息。 (通常有更多更好的信息。)另外,WINDOW_HEIGHT的定义是什么? – molbdnilo
