SFML线程错误

我和朋友正在制作一个简单的多人游戏来练习我们的编码。不幸的是我们遇到了一个问题。 SFML线程系统(不使用std :: thread,因为我的编译器还没有支持它)给了我一个错误。

  

|| === Build:Debug in Clear Void(编译器:GNU GCC编译器)=== |   C:\ Users \ Name \ Documents \ Coding \ SFML work \ Clear_Void \ src \ GameScreen.cpp ||在构造函数' GameScreen :: GameScreen()':|

|| ===构建失败:2个错误,2个警告(0分钟,4秒(秒))=== |

这是我的代码: GameScreen.h

class GameScreen : public Screen
{
public:
    GameScreen();

    void handleInput(sf::RenderWindow&) override;
    void update(sf::RenderWindow&, sf::View&) override;
    void render(sf::RenderWindow&) override;

    void startThread();


private:
    sf::Vector2f moveVal;
    Network network;
    Events eventManager;

    Map m_map;

    sf::Thread networkThread;
};

GameScreen.cpp(相关章节)

GameScreen::GameScreen()
: networkThread(&startThread)
{
    network.Connect();
}

我检查了SFML线程教程,并根据它们,这应该工作。请帮忙。

答案 0 :(得分:0)

startThread应该是静态的。通常,线程函数不能调用非静态成员函数。
