title: Making a sprite always point to another sprite in XNA
body: <p>I have a player sprite (<code>playerTexture</code>) and a crosshair sprite (<code>crossTexture</code>) in my game. I need to make the player sprite always face towards the crosshair.</p>
  
  <p>Does anyone know how to do this? I have tried doing it myself but the math involved boggles my mind. I know there's a rotation parameter in the <code>spriteBatch.Draw()</code> method but I'm unsure how to use it.</p>
  
  <p>Thanks!</p>
