this is the starting position:

this shows that from this orientation the up/down rotation is good:

but when I turn left (the ball is one of those four balls which I added for better orientation):

the up/down rotation looks like this:

oh, yes I see it in the FPS example
     if (left) {
         camera.rotateAxis(camera.getBack().getYAxis(), -TURN_SPEED);
         playerDirection.rotateY(-TURN_SPEED);
      }
      if (right) {
         camera.rotateAxis(camera.getBack().getYAxis(), TURN_SPEED);
         playerDirection.rotateY(TURN_SPEED);
      }
I'll try it

i have created 4 balls: up, down, left and right to visualize it better

what i see is that it seems like it's rotating around the same unchangable axis... what I mean is when the cube rotates, the pivot, axis or whatever it is, doesn't (the cube rotates using some global axis, not it's local) so when it becomes "from the left side" it is rotated as thought it's side was the front... or like so

maybe I forgot something like: cube.recalculateThePivotAndOtherRotationStuffSoThatYouDontHaveProblemsRotatingThisCubeThatYouWasSoHappyAbout();

I'm rotating my cube like so:
               if(right) {
                    cube.rotateY(0.01f);
                    cube.translate(cube.getYAxis());
                }

when I rotate it, it moves down (while rotating), and when I rotate it the similar way with the X axis it moves right (while rotating).

any idea why it acts like that and how to fix it?

It's my first try with this (well exactly ANY) engine and I just can't get it to work
here's the code (sorry for making another thread with "correct my code, please", I just really can't find the critial thing that makes stuff not working):
