title: Flash AS3: isometric grid movement
body: <p>Really desperate help needed for this Flash AS3 question. I am currently creating a game similar to cafe world, farmville etc (social game). Would like to know how could i make an object move in an isometric direction when my mouse move. 
  For example, when I want to build a house, i click on the house build button, and when my mouse move, I want my house object (stored in the library) to be move together with my mouse in an isometric direction. To give you all a better impression of the solution i am looking for, click on this link for a sketch: <a href="http://www.flickr.com/photos/58743938@N07/5497636770/" rel="nofollow">http://www.flickr.com/photos/58743938@N07/5497636770/</a></p>
  
  <p>So i want something like only when my mouse move 20 units more than the original mouse position, then my house item should move to the next grid.</p>
  
  <p>Do clarify with me if there's anything that is unclear. Thanks a lot! :)</p>
