multithreading - 由于模板和线程问题，c++ 11编译失败

Question

我正在尝试按照本教程http://www.cplusplus.com/reference/thread/thread/创建新线程

以下是我编写的相关代码

Game.cpp:

Game :: Game (bool isDebug, bool startNew) {
    // ...
    std :: thread gameThread(Game :: tick);
}

void Game :: tick() {
    std :: this_thread :: sleep_for(std :: chrono :: seconds (1));
    funds += getIncomeRate();
}

Game.hpp:

#ifndef Game_hpp
#define Game_hpp

#include <thread>

using namespace std;

class Game{
    public:
    // ...
        Game (bool, bool);
        void tick();
};

#endif /* Game_hpp */

我在编译过程中遇到的错误说

总的来说，我对C++和模板不是很熟悉，我真的不明白我的代码有什么问题。如果这是一个琐碎的问题，请提前道歉。

你要:

std::thread gameThread(&Game::tick, this);
//                    ^^^           ^^^^
