title: XNA game components
body: <p>I an confused about how to pass values of variables from 1 gamecomponent to another.
  I am using xna 4.0.</p>
  
  <p>I created two gamecomponents, the drawstring and the inputmanager. 
  I want to read the keyboard input of the user and pass it onto drawstring where it will update the position.</p>
  
  <p>I cant add components on drawstring(drawablegamecomponent).
  I can do it on class but not on gamecomponent.
  Can you guys post some examples here. For beginners.</p>
