Hello, im running a modified jme2 version to later support multitouch through http://code.google.com/p/multiplicity/ and i am trying to create an roleplaying game. nifty is showing great as the gui, but i cannot click any of the panels with interaction.
The xml sheet works with my own RPGscreencontroller.java and the de.lessvoid.nifty.examples.controls.ControlsDemoMain.class example.
Since i am running my program with “extends SimpleGame” i cannot use LwjglInitHelper, that seems to work wonders with the ControlsDemoMain example.
So i am trying to work around it with :
[java]private static LwjglInputSystem inputSystem;
initInput();
nifty = new Nifty(new RenderDeviceLwjgl(),
new SoundSystem(new SlickSoundDevice()),
inputSystem,
new TimeProvider());[/java]
where initInput() is a copy out of LwjglInitHelper, and is returning true.
my jme game gets all mouse movement and clicks, so i can move the character.
I´ve also tried
[java]JmeNiftyInputSystem jmeNiftyinput = new JmeNiftyInputSystem();
MouseInput.get().addListener(jmeNiftyinput);
KeyInput.get().addListener(jmeNiftyinput);
jmeNiftyinput.bind(nifty);[/java]
and use that as the inputSystem when initiating nifty, but it´s the same problem, nifty does not get any mouse events.
I don’t understand the problem to be honest 
Can you try to explain it again? Maybe send a bit more code?
Thanks a lot for helping out, I don´t know how much code you need, so i will just post the xml, my screencontroller (which don´t have a lot atm), and the main file, and please tell me if it´s too much and too unorganized, and i will try to create a smaller file that also shows my problem.
The problem is basically that i can use jmonkeyengine perfectly, and nifty shows on top of it, but my problem is that i cannot use the gui with mouse clicks, like nifty does not share mouse events with jmonkeyengine. so, source:

with the interact on one of the images, I´ve also tried buttons and panels with interact, but same result.
[java] |image id=“spell1” x=“120px” y=“10px” filename=“data/Magic_button_red.png” width=“70px” height=“70px”|
|interact onClick=“pstest()” /|

RPGscreencontroller that should interact with the xml:
[java]package multiplicity.appgallery.niftytest;
import de.lessvoid.nifty.Nifty;
import de.lessvoid.nifty.screen.Screen;
import de.lessvoid.nifty.screen.ScreenController;
public class RPGscreencontroller implements ScreenController {
private Nifty nifty;
private Screen screen;
public void bind(Nifty newNifty, Screen newScreen) {
screen = newScreen;
nifty = newNifty;
System.out.println(“bind”);
}
public void onStartScreen() {
System.out.println(“onStartScreen”);
}
public void onEndScreen() {
System.out.println(“onStartScreen”);
}
public void pstest() {
System.out.println(“press test”);
}
}[/java]
which gets the screencontroller from the xml as shown in eclipse when compiling and running
[java]Dec 2, 2010 11:09:33 AM de.lessvoid.nifty.Nifty gotoScreenInternal
INFO: gotoScreenInternal [start]
bind
Dec 2, 2010 11:09:33 AM de.lessvoid.nifty.screen.Screen$StartScreenEndNotify perform
INFO: onStartScreen has ended
onStartScreen
fps: 26[/java]
and finally the main file (its unorganized since its just in progress stuff while i try to learn all this stuff meanwhile) but i think the important stuff should be pretty much up top.

where i would guess the important stuff according to my problem with nifty not being intractable lies within
[java] JmeNiftyInputSystem jmeNiftyinput = new JmeNiftyInputSystem();
MouseInput.get().addListener(jmeNiftyinput);
KeyInput.get().addListener(jmeNiftyinput);
jmeNiftyinput.bind(nifty);
nifty = new Nifty(new RenderDeviceLwjgl(),
new SoundSystem(new SlickSoundDevice()),
jmeNiftyinput,
new TimeProvider());
nifty.fromXml(“data/rpg.xml”, “start”);[/java]
anyways, thanks for for taking the time to help me figure this out

What version of the Nifty JME2 Renderer do you use? I think the current SVN Version looks a bit different.
I’m a bit confused now because you seem to mix Jme Renderer Nifty classes with the native Lwjgl Nifty Renderer classes
A JME2 specific setup tutorial was added to the Nifty wiki at sf.net recently by some other Nifty user. You can find it here: https://sourceforge.net/apps/mediawiki/nifty-gui/index.php?title=Using_Nifty_with_JMonkeyEngine_2. Can you get it to work following that tutorial?
Thanks for posting your code! It is a bit much to understand tho
If the turorial above does not help you, can you zip the whole project and make it available somehow?
Thank you again void, I will try this the second I have the time, guessing monday morning.
I will then give a writeup on what i did and how the results went, for people who might have the same problem.
