NiftyMethodInvoker logException in JME3 trying to call methods from another clas

mcburch · April 29, 2014, 12:25am

So, I am making a JME3 game that is basically like first person asteroids. It is really simple and compact and works fine on its own. I am trying to add a GUI to it and so far neither the XML or the Swing Canvas ways work for me. I am asking about the XML way because the gui shows up everything is fine when I print stuff or do simple operations but when I try to access a method from a class after a button press it throws this error:

So, my xml layout is fine and I have a package with the controller as such:

/*

To change this template, choose Tools | Templates
and open the template in the editor.
*/
package jme3GUI;

import com.jme3.app.Application;

//allows switching of game modes
import com.jme3.app.state.AbstractAppState;
import com.jme3.app.state.AppStateManager;
import de.lessvoid.nifty.Nifty;

//allows Nifty Gui to do its thing
import de.lessvoid.nifty.screen.Screen;
import de.lessvoid.nifty.screen.ScreenController;

import jme3games.*;

public class GUIController extends AbstractAppState implements ScreenController {

//instance of the game class
Main main = new Main();

Application app;
AppStateManager stateManager;
Nifty nifty;
Screen screen;

public void bind(Nifty nifty, Screen screen) {
this.nifty = nifty;
this.screen = screen;
}

//required method
public void onStartScreen() {

}

//required method
public void onEndScreen() {

}

@Override
public void initialize(AppStateManager stateManager, Application app) {

super.initialize(stateManager, app);

}

//event on click
public void playMeteor() {

  //hides the gui
  nifty.gotoScreen("game");
  //nifty.exit();
  //runs the game
  main.runMeteor();

}

//event on click
public void playPong() {
//gets rid of the gui
//nifty.exit(); //go to whatever screen
//runs the game
//main.runPong();
}

//event on click
public void Exit() {
main.CloseMe();
}

}

and then I have a main file that imports my game file and it is as such:

/*

To change this template, choose Tools | Templates
and open the template in the editor.
*/
package jme3games;

//general import for the app
import com.jme3.app.SimpleApplication;

//Nifty GUI imports
import com.jme3.niftygui.NiftyJmeDisplay;
import de.lessvoid.nifty.Nifty;
import jme3GUI.GUIController;

/**

*/
public class Main extends SimpleApplication {

//variable for the controller and gui
GUIController myguicontroller;
Nifty nifty;
NiftyJmeDisplay niftyDisplay;

//instance of the games in the same package
Pop meteor = new Pop();
//Pong pong = new Pong();

public static void main(String Args[]) {
Main app = new Main();
app.start();
}

public void runPong() {
// pong.run()
}

public void runMeteor() {

 //doesnt work when i try calling these methods
 //Only works if i have simple print out stuff
 meteor.makeSphere();
 meteor.makeGameElements();

}//end of hide gui

public void CloseMe() {
System.exit(0);
}

public void simpleInitApp() {

 //NIFTY GUI
 myguicontroller = new GUIController();
 stateManager.attach(myguicontroller);
 
 niftyDisplay = new NiftyJmeDisplay(
         assetManager, inputManager, audioRenderer, guiViewPort);
 nifty = niftyDisplay.getNifty();
 guiViewPort.addProcessor(niftyDisplay);
 //adding the layout
 //points at the start screen from the file
 nifty.fromXml("Interface/GUILayout.xml", "start", myguicontroller);

 
 //nifty.setDebugOptionPanelColors(true);
 
 //makes cursor visible 
 flyCam.setDragToRotate(true);

}

So, the error is shown when I try to make a material for my spheres and if I comment that out it just finds other things to yell at. Any help would be great.

same problem here, couldn’t start a thread on for some reason, so I’ll add to here:

I have:
[java]public class MenuAppState extends AbstractAppState implements ScreenController {[/java]
Where I layout GUI in java:
[java]nifty.addScreen(“Screen_ID”, new ScreenBuilder(“Hello Nifty Screen”){{
controller(new MenuAppState());[/java]
And create button:
[java]control(new ButtonBuilder(“btnQuit”, “Quit”){{
alignCenter();
valignCenter();
height(“5%”);
width(“15%”);
visibleToMouse(true);
interactOnClick(“quitGame()”); // <============

                }}); [/java]

In the same class I implement quitGame() :
[java]public void quitGame() {
app.stop();
}[/java]

But when I press the button, it throws these warnings and does nothing:

logException WARNING: java.lang.Thread run (Thread.java:744)

It throws these warning whenever i call a method from quitGame.
If quitGame() is empty and I press the button, it doesn’t say anything.
When I set a variable in quitGame() in doesn’t say anything either, but it also doesn’t set the variable(?) (debugged it)

Am I doing something wrong?
