Question

所以我尝试了 lwjgl 但我遇到了一个问题，当我尝试创建一个窗口时出现错误，我就是不知道为什么。

我曾尝试将我的 java 版本从 java 16 降低到 14，但这没有用。

主类：

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();
    }
}

当我运行主类时出现此错误（在 java jdk 16 上）：

<块引用>

任务 ':Main.main()' 执行失败。

试试：使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。使用 --scan 运行以获得完整的见解。

我尝试使用信息运行它，这是我的输出：

Answer 1

好吧，问题很简单，我从来没有改变过windows值

在长窗口被设置为空之前

但我发现我必须将它设置为等于 glfwCreateWindow：

之前：

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

之后：

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

Lwjgl 窗口打不开
