[FIXED] LWJGL 3 - GLFW Window crash

Issue

So, I am pretty new to LWJGL and GLFW, and I'm following a tutorial. I'm on MacOS Big Sur 11.5.2 the window does stay open but crashes immediately and doesn't show. Anyone know why this is happening? Tutorial: click here LWJGL Version: 3.2.2 JDK: JavaSE-1.8

Window.java:

package com.bmc.voxel3d;

import org.lwjgl.glfw.GLFW;
import org.lwjgl.glfw.GLFWVidMode;

public class Window {
    private int width, height;
    private String title;
    private long window;
    
    public Window(int width, int height, String title) {
        this.width = width;
        this.height = height;
        this.title = title;
    }
    
    public void create() {
        if(!GLFW.glfwInit()) {
            System.out.println("ERROR: Didn't initialize GLFW.");
            return;
        }
        
        window = GLFW.glfwCreateWindow(width, height, title, 0, 0);
        
        if(window == 0) {
            System.out.println("ERROR: Could not make window.");
            return;
        }
        
        GLFWVidMode videoMode = GLFW.glfwGetVideoMode(GLFW.glfwGetPrimaryMonitor());
        GLFW.glfwSetWindowPos(window, (videoMode.width() - width) / 2, (videoMode.height() - height / 2));
        GLFW.glfwShowWindow(window);
    }
}

and Main.java:

package com.bmc.minecraft;

import com.bmc.voxel3d.Window;

public class Main implements Runnable{
    public Thread game;
    public static Window window;
    public static final int WIDTH = 854, HEIGHT = 480;
    
    public void start() {
        game = new Thread(this, "game");
        game.start();
    }
    
    public static void init() {
        System.out.println("Initializing Game!");
        window = new Window(WIDTH, HEIGHT, "Game");
        window.create();
    }
    
    public void run() {
        init();
        while(true) {
            update();
            render();
        }
    }
    
    private void update() {
        System.out.println("Updating Game!");
    }
    
    private void render() {
        System.out.println("Rendering Game!");
    }
    
    public static void main(String[] args){
        new Main().start();
    }
}

Also, I have -XstartOnFirstThread in the Run Configuration Eclipse 2019

Solution

I assume that you mean that the window is not responding to user input.

The solution is fairly simple, instead of true in the game loop, you need to put !glfwWindowShouldClose(window), which will tell GLFW that it should close when the x button is pressed.
