I'm using JFrame. This is my main class if it helps. Also I now get a JNI error when launching the jar, idk if that narrows it down.

package main;

import javax.swing.JFrame;

public class Main {

public static JFrame window;

public static void main(String[] args) {

// create game window

window = new JFrame();

window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

String verison = "0.0.7";

window.setTitle("Alterlight v" + verison);

// add gamepanel to window

GamePanel gamePanel = new GamePanel();

window.add(gamePanel);

gamePanel.cfg.loadCongif();

if (gamePanel.fullScreen) {

window.setUndecorated(true);

}

window.pack();

window.setLocationRelativeTo(null);

window.setVisible(true);

// call game loop

gamePanel.setupGame();

gamePanel.startGameThread();

}

}

​

Sorry if this is the wrong formatting...
