Title: Delayed input when key is held down
Post by: pentex on November 29, 2010, 10:47:15 pm

Hi, I'm writing a game atm using SFML and I want WSAD to be the movement keys. The problem is that when they are held down to move forwards/backwards etc there is a delay. The player initially moves one iteration forward and then pauses momentarily before the repeated input kicks in and he starts moving forward smoothly. Is there a way to turn this delay off? Or some other solution? I'm used to using XNA where there isn't a delay of this sort.

Thanks!
Stephen

This is because you react on key press events, whereas you should move your character as long as the key is held down.

See sf::Input (tutorial and doc) for the solution to your problem.

Thanks for the quick response. I'm already using sf::input though, I initially checked the documentation and switched from checking window events to using sf::input, but for some reason it still behaves the same way. Here's the code:

Code: [Select]

void ProcessKeyboard(sf::Event Event)
{
const sf::Input& input = window.GetInput();
if (input.IsKeyDown(sf::Key::Escape))
window.Close();

        //old code
//if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code   == sf::Key::W))
//{

// new code
if (input.IsKeyDown(sf::Key::W))
{

Am I missing something?
Thanks,
Stephen

You check inputs only when an event occurs, so you end up with the same problem. Use sf::Input outside your event loop.
