SFML - 流體屏幕更新？

Question

我開始與SFML 2.1但我不能找到如何使程序運行流體

我的意思是，該方案的工作，但除非我做一些事情，比如按下按鈕或移動鼠標，主循環不會運行，

這裏是我的主循環代碼

 window.setFramerateLimit(30); // set max fps to 30 

    while (window.isOpen()) 
    { 
     // this code ignores the framerate limit and doesnt runs when an event is found 
     while (window.pollEvent(event)) 
     { 
       // this code works fine but it wont run unless the user presses a key or moves the mouse 
     } 
    } 

任何想法的例子嗎？

主循環確實運行，你沒有做任何事情。

從教程2.1：

while (window.isOpen()) 
    { 
     // check all the window's events that were triggered since the last iteration of the loop 
     sf::Event event; 
     while (window.pollEvent(event)) 
     { 
      // "close requested" event: we close the window 
      if (event.type == sf::Event::Closed) 
       window.close(); 
     } 

     // clear the window with black color 
     window.clear(sf::Color::Black); 

     // draw everything here... 
     // window.draw(...); 

     // end the current frame 
     window.display(); 
    }
