Using Events to check for inputs ?

[Flaze07]

Should I use Events to check for inputs to i.e move my character or should I use the other one ??

i.e

Code: [Select]

        sf::Event event;
        while (win.pollEvent(event))
        {
            if (event.type == sf::Event::KeyPressed)
            {
                if (event.key.code == sf::Keyboard::Space) chara.jump();
            }
        }

or

Code: [Select]

        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Space)) chara.jump();

which one is better?

Both work, neither is objective better or worse. Pick the one you're more comfortable with writing code for.

Got it, also is it better to

sf::Event event;
        while (win.pollEvent(event))
        {
            if (event.type == sf::Event::KeyPressed)
            {
                if (event.key.code == sf::Keyboard::Space) chara.jump();
            }
        }
 

or

sf::Event event;
        if (win.pollEvent(event))
        {
            if (event.type == sf::Event::KeyPressed)
            {
                if (event.key.code == sf::Keyboard::Space) chara.jump();
            }
        }

You need to use while for the event loop. Check the official tutorial.

They are not equivalent. The KeyPressed event happens once when you press the key, whereas isKeyPressed will return true as long as the key is down, ie continuously for a short while. So in the first case your character will jump once, in the second one it will restart its jump continuously until you release the key. It's easy to workaround (do nothing if a jump is already active), but from a design point of view what you need is an event.

Yeah, thanks Laurent.
Also if I used while wouldn't that means that when I have an input the whole other section of the program that does some stuff wouldn't run and my program would be stuck at the input section ?
