A simple camera changing problem

Hi, dear all. I wrote a simple program HelloMy.java as follows. It extends SimpleGame and I changed the cam's settings in the method setUpCamera(). Then I run it, but I can't turn the camera left or right anymore. Anyone helps?

import com.jme.app.SimpleGame;

import com.jme.scene.shape.Box;

import com.jme.math.Vector3f;

:D, really thank you, man. Really appreciate your help. Thx again.  Really happy now.

The problem is that when the input handler is created in SimpleGame, it is given a camera whose up axis is the y-axis.  That is locked in to prevent rolling.  When you change the camera attributes to use a z up axis, then y is still locked in the input handler.  Unfortunately, you can't change the lock very easily, so your only course of action is to recreate the inputhandler.  This is pretty easy, only 3 lines of code.  So change your setUpCamera like so:

    private void setUpCamera(){
       cam.setLocation(new Vector3f(-5,-1,5));                
        cam.setDirection(new Vector3f(1,0,0));
        cam.setLeft(new Vector3f(0,1,0));
        cam.setUp(new Vector3f(0,0,1));
        /** Create a basic input controller. */
        input = new FirstPersonHandler(this, cam, properties.getRenderer());
          /** Signal to all key inputs they should work 10x faster. */

Good luck on your next steps in jME!

We aim to please.  XD
