I am trying to jump my simple sprite and i have written some code but every time when i press up key which is for jumping the sprite sprite jumps after few seconds , is there any solution here is my code please help as soon..Thanks in advance.

using namespace std;

int main()
{
   sf::VideoMode Vmode1(600,400,32);
   sf::RenderWindow Window1(Vmode1, "Project Aasra");
   Window1.SetFramerateLimit(60);
   Window1.UseVerticalSync(true);

   //SECTION START: Images and Sprites

    double x,y,dx, dy;
    x=y=dx=dy=0;

   sf::Image mario2;
   if(!mario2.LoadFromFile("images/mario2.png")){return EXIT_FAILURE; }
   sf::Sprite mario2_sprite(mario2);


    bool hold =true;
    while(hold)
   {
      sf::Event Event1;

    bool space_down=false;
      while(Window1.GetEvent(Event1))
      {
         //window controls
         if(Event1.Type==sf::Event::Closed) { Window1.Close(); hold=false; }
      }

      //SECTION START: direction keys press
      if(Window1.GetInput().IsKeyDown(sf::Key::Right))  dx+=0.5;

      if(Window1.GetInput().IsKeyDown(sf::Key::Left))   dx-=0.5;

        mario2_sprite.SetPosition(x,y);

      x+=dx;
      y+=dy;

    /*friction*/
      dx*=0.775;


    /*jump*/

      if((Window1.GetInput().IsKeyDown(sf::Key::Up)))
      {
        dy=-4.0;
        space_down=true;
      }

      if (!Window1.GetInput().IsKeyDown(sf::Key::Up)) space_down=false;


    /*gravity*/
      if (mario2_sprite.GetPosition().y<252) dy+=0.1;

    /*Screen Limit*/
    if((mario2_sprite.GetPosition().y + mario2_sprite.GetSize().y) > 252)
    {
        mario2_sprite.SetY(252);
    }

      Window1.Clear(sf::Color(0,255,255));
      Window1.Draw(mario2_sprite);
      Window1.Display();
   }
}
