Question

我正在尝试创建一个线程，但是当我编译时，会出现以下错误：

1>------ Build started: Project: GameServer, Configuration: Release Win32 ------
1>  Heatbeat.cpp
1>C:\Users\Will\Documents\OpenGL\include\SFML/System/Thread.inl(48): error C2064: term does not evaluate to a function taking 1 arguments

我试图让线程接受带有一个参数的函数，但是会生成此错误。这是我的档案：

void Heartbeat::prepareHeartbeat(ClientHandler clients)
{
    std::vector<sf::IpAddress> ips;


    for(int i = 0; i < clients.size(); i++)
    {
        PlayerSession player = clients.getPlayers().at(i);
        sf::IpAddress ip = player.getIp();
        ips.push_back(player.getIp());
        std::cout << player.getIp() << std::endl;
        sf::Thread thread(&Heartbeat::heartbeat, ip);

        thread.launch();

    }
}

有什么建议吗？

更新：我试过

sf::Thread thread(&Heartbeat::heartbeat, this, ip);

同样，但这会返回以下错误：

sf::Thread thread(&Heartbeat::heartbeat, this, ip);

有一个非常好的SFML线程教程here。请仔细查看＆＃34;常见错误＆＃34;。

简单地说，语法不允许您使用SFML的线程执行您想要执行的操作。没有构造函数需要三个参数。

您需要std :: bind您的函数和参数或创建一个仿函数或使您的心跳方法保持静态。

SFML线程初始化不起作用
