java - 窗口打开时出错？

Question

当我制作一个简单的窗口时，它给了我一个错误，我不知道为什么!我使用的是 Linux Mint 64 位。 (戴尔灵越 1764)

错误如下:

org.lwjgl.LWJGLException: X Error - disp: 0x7f81187c9a20 serial: 93 error: GLXBadFBConfig request_code: 156 minor_code: 34
at org.lwjgl.opengl.LinuxDisplay.globalErrorHandler(LinuxDisplay.java:321)

at renderEngine.DisplayManager.createDisplay(DisplayManager.java:27)
at engineTester.MainGameLoop.main(MainGameLoop.java:10)

Exception in thread "main" java.lang.IllegalStateException: Cannot determine close requested state of uncreated window
at org.lwjgl.opengl.Display.isCloseRequested(Display.java:549)
at engineTester.MainGameLoop.main(MainGameLoop.java:14)

这是我的代码:

package engineTester;

import org.lwjgl.opengl.Display;

import renderEngine.DisplayManager;

public class MainGameLoop {

public static void main(String[] args) {
    DisplayManager.createDisplay();

        while(!Display.isCloseRequested()) {
            //game logic
            //render
            DisplayManager.updateDisplay();
        }

        DisplayManager.closeDisplay();
    }

}

然后另一个类是:

package renderEngine;

import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.ContextAttribs;
import org.lwjgl.opengl.Display;
import org.lwjgl.opengl.DisplayMode;
import org.lwjgl.opengl.GL11;
import org.lwjgl.opengl.PixelFormat;  
import org.lwjgl.test.applet.OpenGL;

public class DisplayManager {

private static final int WIDTH = 1000;

private static final int HEIGHT = 700;

private static final int FPS_CAP = 120;

public static void createDisplay() {

    ContextAttribs attribs = new ContextAttribs(3,2);
        attribs.withForwardCompatible(true);
        attribs.withProfileCore(true);

        try {
            Display.setDisplayMode(new DisplayMode(WIDTH, HEIGHT));
            Display.create(new PixelFormat(), attribs);
            OpenGL opengl = new OpenGL();
            GL11.glViewport(0, 0, WIDTH, HEIGHT);
        } catch (LWJGLException e) {
            e.printStackTrace();
        }
    }

    public static void updateDisplay() {
        Display.sync(FPS_CAP);
        Display.update();
    }

    public static void closeDisplay() {

        Display.destroy();

    }

}

Answer 1

经过大量工作后，我最终决定阅读 Minecraft 的源代码，看看他们如何创建 OpenGL 窗口。我将其放入我的代码中，现在窗口可以完美打开!

如果遇到问题，要使其正常工作，请更换

Display.create(new PixelFormat(), attribs);

与

Display.create(new PixelFormat().withDepthBits(24));
