io

Allegro 5 C++ rapid game prototyping framework in a single header-file.

• Define IO_IMPLEMENTATION in one .cpp file before including io.h.
• Derive from io::Game.
• Use IO() macro to run the game.
• Use io() macro to access global game stuff (e.g. input).

#define IO_IMPLEMENTATION
#include "io.h"

class Example : public io::Game
{
public:
    Example() : io::Game("Example", 800, 600, false) {}

    void update() override
    {
        if (io().input.is_key_down(ALLEGRO_KEY_ESCAPE))
        {
            quit();
        }
    }
    
    void render() override
    {
        // ...
    }
};

IO(Example);
