title: issue with gravity in andengine android
body: <p>I attempting to write simple game that include player sprite and obstacles.
  I have implemented a physics world with gravity. I would like when player sprite falling it will be near the obstacle where it falling from, but with gravity the the sprite falling in diagonal and not straight down.</p>
  
  <pre><code>mPhysicsWorld = new PhysicsWorld(new Vector2(0, SensorManager.GRAVITY_EARTH), false);
  ...
  
  public Player(PhysicsWorld world, final float pX, final float pY, final TiledTextureRegion pTextureRegion,
          final VertexBufferObjectManager pVertexBufferObjectManager)
  {
      super(pX, pY, pTextureRegion, pVertexBufferObjectManager);
  
      mPlayerDeff = PhysicsFactory.createFixtureDef(0, 0, 0);
  
      mVertexBuffer = pVertexBufferObjectManager;
      mBoardManager = BoardManager.getInstance();
      mDirection = DIRECTION_RIGHT;
  
      mWorld = world;
  
      mBody = PhysicsFactory.createBoxBody(mWorld, this, BodyType.DynamicBody, mPlayerDeff);
      mWorld.registerPhysicsConnector(new PhysicsConnector(this, mBody, true, false));
  
  }
  </code></pre>
