Keyboard array?

[TheGuerilla]

One of the few things I really liked about SDL was the fact that the keyboard could be gathered from an array; because I could store a record of the last frame by just copying the contents of the array into another and testing for key presses and releases by comparing the two. I don't like testing really anything inside the event poll, so is there any sort of array of the keyboard states in SDL? And if not, is there any other way than checking for key presses/releases than in the event poll? (Perhaps a functions?)

It's really easy to create such an array yourself - a couple of lines of code.

    std::map<int,bool> keys; // Add this somewhere in a class or where it doesn't get destroyed
    // ---
    sf::Event event;
    while(window.pollEvent(event)) {
        switch(event.type) {
            case sf::Event::KeyPressed:
                keys[event.key.code] = true;
                break;
            case sf::Event::KeyReleased:
                keys[event.key.code] = false;
                break;
            default:
                break;
    }
 

every key's state can be checked with keys[sf::Keyboard:<key>]

Can't you simply use sf::Keyboard::isKeyPressed ? (I surely don't understand your needs).

Instead of int use the enum type sf::Keyboard::Key.

Dude I had no idea I could do this. Thanks a ton!

You can use an array or a vector, only Unkown is -1, all the valid keys are in range from 0 to KeyCount - 1.

Or use a map, to be on the safe side, even in presence of unlikely future changes
