Title: Poll Events
Post by: mjtilbrook1 on November 20, 2016, 02:57:32 pm

Hi guys, can someone please explain to me as simply as you can how pollEvents work, im struggling to understand them, like, i get the rest of the code, just not the pollEvent part

thanks



while (gameWindow.isOpen())
   {
      sf::Event event;

      while (gameWindow.pollEvent(event))
      {
         if (event.type == sf::Event::Closed)
            gameWindow.close();
      }

   
      gameWindow.display();
   }

Events are stored in a (hidden) list when triggered.
pollEvent removes an event from this list and initializes its sf::Event argument with it, and returns false if the list is empty and true otherwise.
Since you call pollevent as the condition of a while loop, it processes every events in the list until it's empty.
