title: Libgdx - Having one Entity partially exempt from Phsyics
body: <p>I'm using LibGDX to make a mobile game, now I'm facing a certain issue.</p>
  
  <p>I have a certain Entity which can collide with the wall, when this happens the wall receives a certain force which then causes it to go off the screen and not be positioned properly anymore.</p>
  
  <p>I have tried using LibGDX's isSensor variable but after doing that my Entity crosses straight through the wall.</p>
  
  <p>How can I make it so the wall does stop the Entity from moving through but isn't affected itself by the force of the Entity?</p>
  
  <p>I'm using the physics body editor for my colission shapes as they are not in normal geometrical formats.</p>
  
  <p>Thank you,</p>
  
  <p>Rene</p>
