Hi,

I want to rotate the orientation of scene from portrait to landscape without the logic of game to be affected.

How can i do this?

Thanks!
This code with some adjustment at some values  works perfectly.

 private void moveCamera() {
      SimpleVector oldCamPos=camera.getPosition();
      SimpleVector oldestCamPos=new SimpleVector(oldCamPos);
      oldCamPos.scalarMul(9f);

      SimpleVector carCenter=car.getTransformedCenter();
      SimpleVector camPos=new SimpleVector(carCenter);
      SimpleVector zOffset=car.getZAxis();
      SimpleVector yOffset=new SimpleVector(0, -100, 0);
      zOffset.scalarMul(-250f);

      camPos.add(zOffset);
      camPos.add(yOffset);

      camPos.add(oldCamPos);
      camPos.scalarMul(0.1f);

      SimpleVector delta=camPos.calcSub(oldestCamPos);
      float len=delta.length();

      if (len!=0) {
         /**
          * Do a collision detection between the camera and the ground to prevent the camera from
          * moving into the ground.
          */
         theWorld.checkCameraCollisionEllipsoid(delta.normalize(), new SimpleVector(20, 20, 20), len, 3);
      }

      /**
       * And finally: Look at the car
       */
      camera.lookAt(car.getTransformedCenter());
   }
