I have jme2 application and want to use niftygui 1.3 for ui part. I created my XML ui file and controller which starts succesfully but when I click to button nothing happens.

XML

[xml]<?xml version="1.0" encoding="UTF-8"?>

<nifty>

<useStyles filename="nifty-default-styles.xml" />

<useControls filename="nifty-default-controls.xml" />



<screen id="start" controller="lamao.soh.ui.controllers.TestNiftyScreenController">

Found an issue reason. As mentioned here http://hub.jmonkeyengine.org/groups/gui/forum/topic/cant-interact-with-gui/ I don’t call update method for nifty. Here what I missed in NIftyState:

[java]

@Override

public void update(float tpf)

{

super.update(tpf);

nifty.update();

}

[/java]



Now all events work fine.
