Lwjgl窗口未打开

Question

package ca.immanuel.flappy;


import org.lwjgl.glfw.GLFWVidMode;

import static org.lwjgl.glfw.GLFW.*;
import static org.lwjgl.opengl.GL11.GL_TRUE;
import static org.lwjgl.system.MemoryUtil.NULL;


public class Main implements Runnable {

    private int width = 1280;
    private int height = 720;

    private Thread thread;
    private boolean running = false;

    /*
        LWJGL cant use the GLFWwindow struct because structs don't exist in java
        so we instead use an ID system in Java that's why we use a long.
    */
    private long window;

    public void start() {
        running = true;
        thread = new Thread(this, "Game");
        thread.start();
    }

    private void init() {
        if (!glfwInit()){
            System.out.println("GLFW failed to init!");
            System.exit(-1);
        }

        glfwWindowHint(GLFW_RESIZABLE, GL_TRUE);
        glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
        glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
        glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
        glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
        glfwCreateWindow(width, height, "Flappy Bird", NULL, NULL);
        if (window == NULL) {
            System.out.println("Could not create window");
            System.exit(-1);
        }

        GLFWVidMode vidmode = glfwGetVideoMode(glfwGetPrimaryMonitor());
        glfwSetWindowPos(window, (vidmode.width() - width) /2, (vidmode.height() - height) /2);
        glfwMakeContextCurrent(window);
        glfwShowWindow(window);
    }

    public void run() {
        init();
        while(running) {
            update();
            render();

            if (glfwWindowShouldClose(window) == true){
                running = false;
            }
        }
    }

    private void update() {
        glfwPollEvents();
    }

    private void render() {
        glfwSwapBuffers(window);
    }

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

任务：Main.Main（）失败无法创建窗口

执行任务“：main.main（）”失败。

进程“命令”c：/program files/java/jdk-16/bin/java.exe“以非零退出值-1结束

null

null

好吧，所以问题很简单，我从来没有改变windows值

在长窗口设置为零之前

但我发现必须将其设置为GLFWCreateWindow：

glfwCreateWindow(width, height, "Flappy Bird", NULL, NULL);

window = glfwCreateWindow(width, height, "Flappy Bird", NULL, NULL);
