title: Converting Coordinates and Dimensions to Box2D world
body: <p>I have a level editor that uses a coordinate system based in AndEngine.</p>
  
  <p>Which uses anchor center point to the left lower corner of sprites, and 0,0 is top left corner.</p>
  
  <p>The problem is i am using the physics in my Libgdx project and i use the width, height, x and y coordinates for Box2D Polygon shapes from the xml generated from my level editor.</p>
  
  <p>When i use the width, height, x and y, the bodies are placed at positions i don't want them to be placed at and way to big.</p>
  
  <p>With that being said, how do i make the coordinates, and dimensions show up in the same way as created in the editor?</p>
