WASD keys only move camera forward and strafe left to right but disabled up or down directions?

Okay so I used inputManager.clearMappings() then remapped the mouse for rotations and now I’m trying to make it so the wasd keys will move the camera in the direction it is facing with the exception of moving up or down. (I’ll later make the camera move up/down accordingly with the terrain but I’m still learning so its baby steps right now, I can’t wait to help contribute back to the community!)

So any solutions? here is my code.

Basically I load up a player model(box) some terrain and a skybox, then clear mappings on flycam then remap them with the ones i want

[java]package mygame;

import com.jme3.app.SimpleApplication;

import com.jme3.material.Material;

import com.jme3.math.ColorRGBA;

import com.jme3.math.Vector3f;

import com.jme3.math.Quaternion;

import com.jme3.math.;

import com.jme3.renderer.RenderManager;

import com.jme3.scene.Geometry;

import com.jme3.scene.shape.Box;

import com.jme3.scene.

import com.jme3.input.ChaseCamera;

import com.jme3.input.;

import com.jme3.input.controls.

import com.jme3.light.*;

import com.jme3.math.Matrix3f;

import com.jme3.math.FastMath;

    public class Main extends SimpleApplication {

    private Spatial player_placeholder;

    public static void main(String[] args) {

    Main app = new Main();



    public void simpleInitApp() {

    //Load Players’ place holder

    //Load Player model

    player_placeholder = assetManager.loadModel(“Models/player_piece.j3o”);

    //Load Players Materials

    Material player_placeholder_mat = new Material(assetManager, “Common/MatDefs/Misc/Unshaded.j3md”);

    //Attach materials to the player



    //Attach player to the stage/world


    //Move to a start location

    player_placeholder.move(0, 1, 0);

    //Load skyBox and Floor/ground

    Spatial skyBox = assetManager.loadModel(“Scenes/mainSkyBox.j3o”);


    Spatial ground = assetManager.loadModel(“Scenes/mainTerrain.j3o”);


    //Move gound a bit lower so camera can see by default


    // You must add a directional light to make the model visible!

    DirectionalLight sun = new DirectionalLight();

    sun.setDirection(new Vector3f(-0.1f, -0.7f, -1.0f).normalizeLocal());


    //Disable cursor view and lock cursor to center of screen to enable FPS views





    //Clear all input mappings – scince we don’t need alot of the preset ones its efficient this way.


    //Recreate FPS Mouse mappings

    inputManager.addMapping(“FLYCAM_Left”, new MouseAxisTrigger(0, true));

    inputManager.addMapping(“FLYCAM_Right”, new MouseAxisTrigger(0, false));

    inputManager.addMapping(“FLYCAM_Up”, new MouseAxisTrigger(1, false));

    //Add listener for the FPS mouse mappings

    inputManager.addListener(analogListener, new String[]{“FLYCAM_Left”, “FLYCAM_Right”, “FLYCAM_Up”, “FLYCAM_Down”});

    //Recreate FPS WASD keyboard mappings where the player will move with enviroment

    //Add listener for the WASD keyboard mappings

    inputManager.addListener(analogWasdListener, new String[]{“Player_forward”});


    //FPS mouse Mappings

    public void onAnalog(String name, float value, float tpf) {

    //FPS WASD keyboard mappings

    private AnalogListener analogWasdListener = new AnalogListener(){

    public void onAnalog(String name, float value, float tpf){


    //Move player forward




    public void simpleUpdate(float tpf) {


    public void simpleRender(RenderManager rm) {

    //TODO: add render code

Why dont you create your own FlyCam, copy the code and add the functions you need?

Im assuming i have to do some kind if trigonometry to make it move per individual needed axis,

Not quite sure if i have to do this manually or if there is a helpfull function to to this…

Yep found it: http://www.hub.jmonkeyengine.org/wiki/doku.php/jme3:beginner:hello_collision

All the way at the bottom, I think that code will work.

Curious: is there a reason you are rebuilding the functionality of the default fly cam?

Just to learn mostly, I completly forgot that there was a system the facilitated a player controls(found in that link in my last post) that incorporated physics and movement, walking etc
