How to use FirstPersonHandler

Hi All!

I search for a good tutorial about FirstPersonHandler.

I want to use it in my game, but i don't know how.

Here is my code so far…

package FlightSimulator;
import com.jme.renderer.*;
import com.jme.util.*;
import com.jme.system.*;
import com.jme.math.*;
import com.jme.input.*;
import com.jme.scene.shape.*;

import com.jme.bounding.*;
import com.jme.scene.state.*;
import com.jme.image.*;
import com.jmex.terrain.TerrainBlock;
import com.jmex.terrain.util.*;
import javax.swing.ImageIcon;

import jmetest.flagrushtut.lesson5.FlagRushHandler;

import com.jme.light.*;

I've got a terrain, but i can't move my camera with WASD or mouse...
This is probable i noob question, because i'm just started with jME.
Can sombody help me?

PS: Sorry for my bad English, but my motherlanguage is Dutch and this is the first year we teach English at school...

jmetest.input.action.TestFirstPersonController gives you an example…

I think you're missing the input.update(interpolation); line in your update method…

I could be wrong, since I usually use SimpleGame instead of BaseGame. Good luck.
