title: how to flip a sprite in c#
body: <p>I'm making a little game based on XNA game development's tutorial game "shooter"... after a bit of trial and error, I made my own animated sprite that i can move around the screen. The problem is, he's always facing right.</p>
  
  <p>How can i change this (image below) so that he faces the right direction every time the key event is pressed?!</p>
  
  <p>I'm pretty new to C# as you might have guessed, and I realize this may be more complicated than i thought, so i just need to know how to make the sprite face right when moving right and left when he's moving left.</p>
