   At the moment, the body is taken out of the first world and placed in the 
new. Here is the code ...



void dBodySetWorld (dxBody *body,  dxWorld* world)
{
  dAASSERT (body);

  if (body->world == 0  &&  world == 0)
    return;


  if (world)
  {
    if (body->world)   // remove from current world.
    {
      removeObjectFromList (body);
      if (body->world)
        body->world->nb--;
    }

    addObjectToList (body,  (dObject **) &world->firstbody);
    world->nb++;
  }
  else
  {
    removeObjectFromList (body);
    if (body->world)
      body->world->nb--;
  }

  body->world = world;
}
