title: Calculating distance on a hexagon grid
body: <p>What I am trying to do is find how many hexagons are in between two points on a hex grid. I have tried searching online for a formula but I have not been able to find one that matches the type of hex grid I am using.</p>
  
  <p>The hex grid is laid out like this one with the same coordinate system: <a href="http://www.gamedev.net/index.php?app=core&amp;module=attach&amp;section=attach&amp;attach_rel_module=ccs&amp;attach_id=1962">http://www.gamedev.net/index.php?app=core&amp;module=attach&amp;section=attach&amp;attach_rel_module=ccs&amp;attach_id=1962</a></p>
  
  <p>I am aware that this may not be possible with this coordinate system but this is a last ditch effort before I go back and change it.
  Thank you very much in advance.</p>
