KeyboardStateExtensions

class KeyboardStateExtensions : System.Object

Extensions for the XNA T:Microsoft.Xna.Framework.Input.KeyboardState class.

This provides state-aware functions for detecting changes in the keyboard state, without having to track the previous state in each object that wants to know about key presses.
