Nifty GUI - Problem detecting Mouse Input

PauloAlvares · October 30, 2014, 4:35pm

Hello,
I’m having some trouble to detect the mouse input on nifty GUI.
The thing is, i’ve done a Menu with some options, and it works fine, it recognize when i click on NovoJogo(NewGame) button, and load the game, and chage appStates etc… But now i’m trying to create a pause screen, that will pause the game, and show a pause screen with some options, i could do this part, the appState is Pausing, and the screen is changing from HUD to Pause Screen, BUT i put a label with a <interact onRelease=“unpause()”> on XML, the same as i’ve done at the MenuScreen, but it don’t work… it do not call the function to unpause the game.
1 - i’ve attached the screenControl to the stateManager, as much as the initialize method is called.
2 - i’ve set a PauseAppState to do the dirt thing…

here is the PauseAppState.java:

package HdI.AppStates;

import HdI.ScreenControls.PauseScreenControl;
import com.jme3.app.Application;
import com.jme3.app.SimpleApplication;
import com.jme3.app.state.AbstractAppState;
import com.jme3.app.state.AppStateManager;
import com.jme3.niftygui.NiftyJmeDisplay;

/**

public class PausedAppState extends AbstractAppState {
    
    SimpleApplication app;
    
    NiftyJmeDisplay niftyDisplay;
    
    AppStateManager stateManager;
    
    public PausedAppState(NiftyJmeDisplay niftyDisplay){
        this.niftyDisplay = niftyDisplay;
    }
    
    @Override
    public void initialize(AppStateManager stateManager, Application app) {
        super.initialize(stateManager, app);
        this.app = (SimpleApplication)app;
        this.stateManager = stateManager;
        this.stateManager.getState(GameRunningAppState.class).pause(true);
        pause();
    }
    
    @Override
    public void update(float tpf) {
        //TODO: implement behavior during runtime
    }
    
    @Override
    public void cleanup() {
        super.cleanup();
        stateManager.getState(GameRunningAppState.class).pause(false);
        unpause();
    }
    
    
    private void pause(){
        PauseScreenControl pauseScreenControl = new PauseScreenControl(app);
        niftyDisplay.getNifty().registerScreenController(pauseScreenControl);
        stateManager.attach(pauseScreenControl);
        niftyDisplay.getNifty().gotoScreen("pause");
    }
    private void unpause(){
        PauseScreenControl pauseScreenControl = app.getStateManager().getState(PauseScreenControl.class);
        niftyDisplay.getNifty().unregisterScreenController(pauseScreenControl);
        stateManager.detach(pauseScreenControl);
        niftyDisplay.getNifty().gotoScreen("inGame");
    }
}

Here is the PauseScreenControl.java


/*

public class PauseScreenControl extends AbstractAppState implements ScreenController{
    
    SimpleApplication app;
    
    AppStateManager stateManager;
    
    PausedAppState pausedAppState;
    
    public PauseScreenControl(SimpleApplication app){
        this.app = (SimpleApplication) app;
    }
    
    @Override
    public void initialize(AppStateManager stateManager, Application app) {
        super.initialize(stateManager, app);
        //TODO: initialize your AppState, e.g. attach spatials to rootNode
        //this is called on the OpenGL thread after the AppState has been attached
        this.app = (SimpleApplication) app;
        this.stateManager = stateManager;
        System.out.println("1\n--\n--\n--\n--\n--\n--\n--\n--");
        System.out.println(stateManager.getState(PausedAppState.class).toString());
        System.out.println("2\n--\n--\n--\n--\n--\n--\n--\n--");
        
//        app.stop();
    }
    
    @Override
    public void update(float tpf) {
        //TODO: implement behavior during runtime
    }
    
    @Override
    public void cleanup() {
        super.cleanup();
        //TODO: clean up what you initialized in the initialize method,
        //e.g. remove all spatials from rootNode
        //this is called on the OpenGL thread after the AppState has been detached
        stateManager.getState(GameRunningAppState.class).unPause();
    }
    
    public void unPause(){
        app.stop();
        app.getStateManager().getState(GameRunningAppState.class).unPause();
    }

    public void bind(Nifty nifty, Screen screen) {
        
    }

    public void onStartScreen() {
        
    }

    public void onEndScreen() {
        
    }
}

Here is the Pause_Screen.XML

        &lt;panel id="panel" height="25%" width="35%" align="center" valign="center" backgroundColor="#f60f" childLayout="center" visibleToMouse="true"&gt;
            &lt;interact onRelease="unPause()"/&gt;
            &lt;effect&gt;
                &lt;onStartScreen name="move" mode="in" direction="top" length="300" startDelay="0" inherit="true"/&gt;
                &lt;onEndScreen name="move" mode="out" direction="bottom" length="300" startDelay="0" inherit="true"/&gt;
                &lt;onHover name="pulsate" scaleFactor="0.008" startColor="#f600" endColor="#ffff" post="true"/&gt;
            &lt;/effect&gt;
            &lt;text id="text" font="Interface/Fonts/font.fnt" text="Pause" align="center" valign="center" /&gt;
        &lt;/panel&gt;
    &lt;/layer&gt;
&lt;/screen&gt;

</nifty>

I did not put the .xml int the code tag because it was weird…

Thanks.

YAY!
Solved it
For some reason, the xml need to be read after the controller is registered at nifty.
And doing it, my problem is solved. \o/
If someone wants to see my code, just ask for it
