Another Input Rectifier

Another Input Rectifier (Air) is designed to make working with input in XNA easier.

Two Main Interfaces

public interface IDigitalControl
{
    public bool Pressed { get; }
}

public interface IAnalogControl
{
    public float Value { get; }
}

These two interfaces form the basis for the rest of the library.

Air

The main class of the library. Air is a game component so its update method will be called automatically. Make sure to add it to your game's components like so:

public YourGame()
{
    ...
    Components.Add(new Air(this));
}

Keyboard Controls

The only thing that is implemented right now. You can create a keyboard control by calling

IDigitalControl myControl = Air.CreateKeyboardControl(Keys.Space);

This creates a regular digital control where myControl.Pressed will be true on any frame that the key is down on. If you only want myControl.Pressed to be true the first time the button is pressed (i.e. it wont repeat) then you want a DigitalFilterControl

IDigitalControl myControl = new DigitalFilterControl(Air.CreateKeyboardControl(Keys.Space));

or the much easier

IDigitalControl myControl = Air.CreateKeyboardControl(Keys.Space).Filter();

Extensions

Can create keyboard controls directly from the Xna.Framework.Input.Keys enum

Keys.Space.ToDigitalControl()

Digital Extension Methods

Any class the implements IDigitalControl will also recieve these extension methods

• Filter() - returns a filtered (or one-shot) version of the control.
• Analog() - returns an analog version of the control where IAnalogControl.Value will be 1 when the button is pressed and 0 otherwise.

Work in progress

Still lots to do. Add methods for the mouse and gamepads. For now Air also provides access to the raw input state through these properties

• Air.MouseState and Air.PreviousMouseState
• Air.KeyboardState and Air.PreviousKeyboardState
• Gamepads can't be a property because you need to know the player
  • Air.GamePadState(PlayerIndex player) and Air.PreviousGamePadState(PlayerIndex player)
