Function do not works
« on: January 27, 2013, 11:43:53 pm »
Hi!

I am using this code:

sf::RenderWindow window(sf::VideoMode(800, 600, 32), "");
window.setKeyRepeatEnabled(false);

But, when I check if a key was pressed, the event runs (is triggered) 2 times.

To check the key, I use:

void GameManager::Update(sf::Event event)
{
ReleasedKey=sf::Keyboard::KeyCount; //basically "NoKey"
PressedKey =sf::Keyboard::KeyCount; //bascically "No Key"

switch (event.type)
{
    case sf::Event::KeyReleased: ReleasedKey=event.key.code;
    case sf::Event::KeyPressed: PressedKey=event.key.code;
default: break;
}

}

And:

GameManager game;
...
while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed) window.close();
            game.Update(event);

            if (game.keyboard_check_pressed(sf::Keyboard::A))
                std::cout << 'A' << endl;
        }

I can not find the error... Please help me.

Note: I use Windows 7, Code::Blocks, MinGW, SFML 2.0.

Please read this then... ;)

What exact SFML version, what OS, what hardware, etc...

My blind guess would be Linux and this thread (yes the search function works even on your end). :)

My blind guess (since you're using win7 and not linux :D): unless you know what you're doing, use break in your switch cases.

Here for one key pressed (and released) you go in your second case twice, once when the key is pressed, another one when the key is released.

and this thread (yes the search function works even on your end).
I saw this topic and I imagined that someone would tell him.
And I do not like (I hate) this internal search engine.
I always 'google' this way: site:sfml-dev.org 'my keywords here'.
I 'googled' before asking.

Solved.

Thanks!

Yeah, I wish it was better and specially that the MySQL wouldn't disconnect randomly when doing a full search... :-\
