其他物体（暂时没用，可以添加增加游戏性）

#ifndef UNFLYER_H#define UNFLYER_H#include <QtWidgets>#include "global.h"class UnFlyer : public QGraphicsObject {Q_OBJECTpublic:UnFlyer(QGraphicsItem *parent = 0);~UnFlyer();enum {TYPE = UserType + 1};int type() const;};#endif // UNFLYER_H

#include "unflyer.h"UnFlyer::UnFlyer(QGraphicsItem *parent) : QGraphicsObject(parent) {}UnFlyer::~UnFlyer() {}int UnFlyer::type() const {return UserType + 1;}

一切以下载的源码为主（20多个类，天知道我有没有粘错。。。），欢迎大家补充、改进
