General / Real-time inputs, rotate a square.

« on: March 12, 2011, 08:52:00 pm »

Hi.
I have some problems with input, when I try to rotate the square it stops for like 0.1 sec right after I press the key, and then it continue the rotation.

Code: [Select]


#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>

int main()
{

sf::RenderWindow Game(sf::VideoMode(640, 480, 32), "Rotate");
Game.SetFramerateLimit(64);

sf::Shape Firkant;

Firkant.AddPoint(300, 300);
Firkant.AddPoint(400, 300);
Firkant.AddPoint(400, 400);
Firkant.AddPoint(300, 400);
Firkant.SetCenter(350.0f,350.0f);
Firkant.Move(300.0f, 200.0f);

const sf::Input& Input = Game.GetInput();

while(Game.IsOpened())
{
sf::Event Event;

while(Game.GetEvent(Event))
{

if (Event.Type == sf::Event::Closed)
Game.Close();

if (Input.IsKeyDown(sf::Key::Down))
Firkant.Rotate(10);
}

Game.Clear();

Game.Draw(Firkant);

Game.Display();
}
return EXIT_SUCCESS;
}

General / New to SFML

« on: March 06, 2011, 01:09:50 pm »

Hi!
I just stumbeled across SFML and it seemed like it is an nice litte C++ API. However I am also pretty new to the C++ language, and I am getting some problems with the tutorials that I have been watching. I think it is because I do not really understand the linking stuff. First I watched , and I managed to get that one working. However I can't get this one working , because I'm not really sure what I need to add in the linkers and maybe more important why I need to add the additional stuff.

I'am also wondering what are the main differences between the SFML2 and SFML-1.6?
