Creating Events

When a class, such as the InputManager needs to send input events, such as keypresses, it creates them using their constructor:

Key k('A'); //-- Create a printable Key
Key k2(Key::KEY_ARROW_UP); //-- Create a control key

Some implementations, such as the SDL input backend, receive input events from SDL as SDL types (i.e. SDL_Keycode, SDL_WindowEvent). To create Robot Devastation input events from them, the SDLEventFactory can be used. It follows the factory pattern, owning a table to convert from SDL types to the corresponding Key.

Once created, they can be sent to the corresponding listeners, either manually o through the helper methods present in the MockInputManager.
