SFML Input Manager
« on: March 28, 2014, 05:10:05 am »
Hi, I thought it'd be good to share something I made recently.

https://github.com/dabbertorres/SwiftInputManager

Here's the example of use on github:
#include <SFML/System.hpp>
#include <SFML/Window.hpp>

#include "KeyboardManager.hpp"
#include "MouseManager.hpp"

int main(int argc, char** argv)
{
    sf::Window window(sf::VideoMode(800, 600, 32), "SFML");

    swift::KeyboardManager keyboard;
    swift::MouseManager mouse;

    keyboard.newBinding("exit", sf::Keyboard::Escape, [&window]()
    {
        window.close();
    });

    mouse.newBinding("exit", sf::Mouse::Right, [&window]()
    {
        window.close();
    });

    while(window.isOpen())
    {
        sf::Event event;

        while(window.pollEvent(event))
        {
            keyboard(event);
            mouse(event);

            switch(event.type)
            {
                case sf::Event::Closed:
                    window.close();
                    break;
                default:
                    break;
            }
        }

        window.clear();

        window.display();
    }

    return 0;
}
 

Multiple uses of the same button are possible too.

An improvement that I'd like to make in the future though are for multiple keypresses, (Ctrl+A, etc).

Nothing too exciting, but in my own bigger projects I figured this would be a nice way of keeping all of the input handling of keypresses and such wrapped up. It works great for me, so I figured I'd share it, and if anyone is willing, share what they think of it. Thoughts on the quality of the code (I'd love feedback, I haven't shared much of my own, and as I'm pretty much self-taught...), etc, would be great!

Looks rather useful.  Just wondering even though it might be overkill why not a SFML.net version too? :P C# using events but not sure about the other .net languages though so it should be interesting.
I have many ideas but need the help of others to find way to make use of them.

I don't know C# all that well is mainly why. May be a good starting to point to get to know the language better though.

I believe it is possible to call C++ code from C# though, you may do some research into that. If you got that down, that'd definitely give you a look into more of the stuff people have made on here.

StormWingDelta, you don't need to go around asking for everything to be written in C# for you  :) Anyways its not difficult to port it yourself if you want it + you get experience. To my point, something very similar to this already exists in my NetEXT Input module if you dare to take a look.  ;)

On a side note this is not directly possible, you need a C style function interface to call unmanaged code, hence CSFML.

Not strictly true. You can use C++/CLI to interface between C++ and .NET, wrapping C++ classes in a CLI wrapper. But this isn't compatible with Mono (to the best of my knowledge).
UnitTest11 - A unit testing library in C++ written to take advantage of C++11.

All code is guilty until proven innocent, unworthy until tested, and pointless without singular and well-defined purpose.

This could be useful if extended with more functions.
Take a look at Thors action handling http://www.bromeon.ch/libraries/thor/

Also a really near feature would be to support multiple mice devices and keyboards. In WIN, this is done using raw input. Take a look at the ManyMouse library. Its a pretty old lib but it works (using it in a current project). You have to read from connected HID. ManyMouse works has also support for Mac OSX and Linux, but I have only tested it on Windows so far.
But you have to create the multiple keyboard by yourself but I believe you can take a lot of the code from ManyMouse.
http://icculus.org/manymouse/

As for now, I have no reason to use this since I am using Thor.
Good luck and I really hope more people considers to be wanting multiple device support  ::)

Yes that is true and it is possible to do that. But as you said, it isn't cross platform and MS doesn't even support it anymore.  :P

I'm late but I find your code very interesting and useful. I just don't get why you name the bindings, this std::string is useless isn't it ?

It could be improved following Thor's combinaisons of actions... but you made this to be simple I think. If one does need more, he can use Thor directly :)

Thanks! Glad to hear someone else found it useful in some way.

And yeah, I guess the strings are "useless", but I found that to be the best way of having different keys in the map. For example, if you want to call something upon the press of a key, AND something called upon release of the same key. I considered an enum, but then the user would have to make his own/add to it, and I didn't like that.

It definitely could be improved. I like what Nexus did with Thor's Actions, I might try to improve this more in the future, but we'll see.

Been a while, but I made a small update to this recently, by adding a call function.

It does two things: Make the std::string keys somewhat useful, and essentially allows you to simulate a keypress in code, by directly calling the function you bound to a key.

I found it useful in a few cases I ran into.
