jMonkeyEngine - rotate with mouse like in first-person games

can someone give me sample of code that will rotate my player please? I want achieve same control like in classical fps (w,a,s,d + mouse). Something with FlyByCamera but i don't know how to add it. Code is without errors. Thanks.
here are methods that are related to control

Can you try something like the methods from an example:

walkDirection.set(0,0,0);
if(left)
walkDirection.addLocal(camLeft);
if(right)
walkDirection.addLocal(camLeft.negate());
if(up)
walkDirection.addLocal(camDir);
if(down)
walkDirection.addLocal(camDir.negate());
player.setWalkDirection(walkDirection);
cam.setLocation(player.getPhysicsLocation());
}
private void setupKeys() {
inputManager.addMapping("Lefts", new KeyTrigger(KeyInput.KEY_A));
inputManager.addMapping("Rights", new KeyTrigger(KeyInput.KEY_D));
inputManager.addMapping("Ups", new KeyTrigger(KeyInput.KEY_W));
inputManager.addMapping("Downs", new KeyTrigger(KeyInput.KEY_S));
inputManager.addMapping("Space", new KeyTrigger(KeyInput.KEY_SPACE));
inputManager.addListener(this,"Lefts");
inputManager.addListener(this,"Rights");
inputManager.addListener(this,"Ups");
inputManager.addListener(this,"Downs");
inputManager.addListener(this,"Space");
}
public void onAction(String binding, boolean value, float tpf) {
if (binding.equals("Lefts")) {
if(value)
left=true;
else
left=false;
} else if (binding.equals("Rights")) {
if(value)
right=true;
else
right=false;
} else if (binding.equals("Ups")) {
if(value)
up=true;
else

LibGDX scene2d stage does not show buttons

I'm using LibGDX v 0.9.7. This code worked just fine some days ago, it doesn't anymore for some reason and doesn't generate error messages. The files being referred to in the code are all present: in the data folder within the LibGDX assets folder. Thoughts?

How to build walls for a maze / labyrinth / dungeon?

The code I use I just took from an example and it does build a wall to my scene:
/** This loop builds a wall out of individual bricks. */
public void initWall() {
float startpt = brickLength / 4;
float height = 0;
for (int j = 0; j < 15; j++) {
for (int i = 0; i < 6; i++) {
Vector3f vt =
new Vector3f(i * brickLength * 2 + startpt, brickHeight + height, 10);
makeBrick(vt);
}
startpt = -startpt;
height += 2 * brickHeight;
}
}
/** This method creates one individual physical brick. */
public void makeBrick(Vector3f loc) {
/** Create a brick geometry and attach to scene graph. */
Geometry brick_geo = new Geometry("brick", box);
brick_geo.setMaterial(wall_mat);
rootNode.attachChild(brick_geo);
/** Position the brick geometry */
brick_geo.setLocalTranslation(loc);
/** Make brick physical with a mass > 0.0f. */
brick_phy = new RigidBodyControl(2f);
/** Add physical brick to physics space. */
brick_geo.addControl(brick_phy);
bulletAppState.getPhysicsSpace().add(brick_phy);
}
Now I wonder if I should use this code to build up an entire labyrinth / dungeon or if this is best modelled outside the program eg. in blender instead like a .scene and then read into the program? The entire program is

In your example you have about 100+ bricks - just imagine how many of them you'll need for full dungeon and how it will kill your physics performance :). It's almost impossible do create playable game with this approach.
You should create some static mesh and divide it into corridors, rooms, etc. so you could draw only visible part of your level. If you really want to create destructible environment you should still use static mesh and dynamically replace parts of it with the bricks when the wall should be destroyed.

I want the green person to stay on the ground but I can't seem to change the physicslocation to appropriate. Do you have any idea? I took this program and just switched the character from oto to ninja:
http://code.google.com/p/jmonkeyengine/source/browse/trunk/engine/src/test/jme3test/bullet/TestWalkingChar.java
Do you have any idea how I can make the camera zoom out so that the whole green person is displayed and change the location of the green person so that he is on the ground?
I've noticed that I can change the location of the main char with this
character.setPhysicsLocation(new Vector3f(-140f, 9.9f, -9f));
but when I put in lower y coordinates the main char drops through the ground and then floats way up in the sky like he ended up on the top of everything when he went through the ground. I could run the example with Oto perfectly, it's changing the main char to ninja that doesn't work for me.
Update
When using setlocaltranslationinstead of setphysicallocationmy main char gets located in the air:
Update 2
After scaling the main char:
model.scale(0.25f);
as suggested in the answer, the rendering is much better:
Update 2
After some more manipulation, it looks more like the way I want:
private void createCharacters() {
CapsuleCollisionShape capsule = new CapsuleCollisionShape(3f, 4f);
character = new CharacterControl(capsule, 0.01f);
model = (Node) assetManager.loadModel("Models/Ninja/Ninja.mesh.xml");
model.setLocalScale(0.15f);
// ninja.setViewDirection( new Vector3f( 1, 0, 1 ) );
// model.rotate(0.0f, -3.0f, 0.0f);
float scale = 0.25f;
model.scale(scale, scale, scale);
model.addControl(character);
character.setPhysicsLocation(new Vector3f(-141f, 10.5f, -9f));
model.setShadowMode(ShadowMode.CastAndReceive);
// model.setLocalTranslation(0, 50, 0);
character.setViewDirection(new Vector3f(1, 0, 0));
rootNode.attachChild(model);
getPhysicsSpace().add(character);
// BlenderKey blenderKey = new BlenderKey(
// "objects/creatures/alien/alien.mesh.xml");
// Node alien = (Node) assetManager.loadModel(blenderKey);
// alien.setLocalTranslation(new Vector3f(-145, 21, -10));
// rootNode.attachChild(alien);
BlenderKey blenderKey2 = new BlenderKey("Models/Oto/Oto.mesh.xml");
Spatial man = (Spatial) assetManager.loadModel(blenderKey2);
man.setLocalTranslation(new Vector3f(-140, 10, -10));
// man.setShadowMode(ShadowMode.CastAndReceive);
rootNode.attachChild(man);
}

I suspect there are 3 things that could make your character appear to be hovering:
Your character is hovering. In this case you'd want to use character.setLocalTranslation(0, -20, 0) to adjust where your character is located (may have to adjust the -20 to some other negative number)
Your character's scale is too big compared to the ground's scale (it sounds like this is a problem you want to fix anyways). To fix this, you'd want to use character.scale(.25) (where the .25 can be adjusted to whatever number works for you
You don't have shadows on the ground. This really links your character to the ground and gives the feeling that they're connected in some way. For this, you'll probably want to use object.setShadowMode(RenderQueue.ShadowMode.Receive) for all your terrain objects, and character.setShadowMode(RenderQueue.ShadowMode.CastAndReceive) on your character object.
The JMonkeyEngine javadoc's are pretty good - If you haven't already I would suggest looking there to help figure out what you're capable of doing with your engine. http://jmonkeyengine.org/javadoc/index.html

Why is my character either hovering or falling through the floor?

I'm making a simple 3D scene with a character and a floor but the character is hovering, or falling through the scene if I put the y coordinate to a negative.
private void createCharacters() {
CapsuleCollisionShape capsule = new CapsuleCollisionShape(3f, 4f);
character = new CharacterControl(capsule, 0.01f);
model = (Node) assetManager.loadModel("Models/Ninja/Ninja.mesh.xml");
float scale = 0.25f;
model.scale(0.05f, 0.05f, 0.05f);
model.addControl(character);
character.setPhysicsLocation(new Vector3f(0, -0.15f, 0));
model.setShadowMode(ShadowMode.CastAndReceive);
character.setViewDirection(new Vector3f(1, 0, 0));
rootNode.attachChild(model);
getPhysicsSpace().add(character);
}
The above code makes the character fall through the scene. Changing it just a little bit to this makes the character hover:
character.setPhysicsLocation(new Vector3f(0, -0.09f, 0));
If you want to inspect all of the code it's here

It appears this is due to this line of code:
CapsuleCollisionShape capsule = new CapsuleCollisionShape(3f, 4f);
and then you are scaling down the model. I dont know what the values passed in are, but i suppose one is a radius and the other one is a height, try moving down that 3f and that 4f to something lower, like 1.0f and 2.0f.
It seems the collision detection is pushing your character upwards because its collision shape is a capsule, which is of a different size than the model, and the model is placed in the middle of the capsule.
