我用的是Mac OS X。IDE是Intellij。由于某种原因,我在尝试运行此代码时出现错误。该代码是一个lwjgl游戏引擎。

public class Main implements Runnable{
private int width = 1280;
private int height =720;
private String title = "Flappy";
private boolean running = false;
private Thread thread;
private long window;
public void start(){
running = true;
thread = new Thread(this, "Display");
//this will call the run method that we created below by using our implemented Runnable
thread.start();
}
public void run(){
init();
running = true;
while(running){
update();
render();
if(glfwWindowShouldClose(window)){
running = false;
}
}
}
//init initializes all of our stuff
private void init(){
if(!glfwInit()){
throw new IllegalStateException("Unable to initialize GLFW YOOO");
}
// Configure our window
glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE); // the window will stay hidden after creation
glfwWindowHint(GLFW_RESIZABLE, GLFW_TRUE); // the window will be resizable
window = glfwCreateWindow(width, height, title, NULL, NULL);
if(window == NULL){
throw new RuntimeException("Failed to create the GLFW window");
}
GLFWVidMode vidmode = glfwGetVideoMode(glfwGetPrimaryMonitor());
glfwSetWindowPos(window, (vidmode.width() - width) / 2, (vidmode.height() - height) / 2);
// Make the OpenGL context current
glfwMakeContextCurrent(window);
// Enable v-sync
glfwSwapInterval(1);
// Make the window visible
glfwShowWindow(window);
}
public void update(){
glfwPollEvents();
}
public void render(){
glfwSwapBuffers(window);
}
public static void main(String[] args){
new Main().start();

阅读了一些帖子后,我尝试在编辑配置和程序参数中添加-XstartOnFirstThread,但没有帮助。我的错误在下面。如果有人能帮忙,谢谢…使用Intellij的Mac。错误添加如下:
Caused by: java.lang.IllegalStateException: GLFW windows may only be created on the main thread and that thread must be the first thread in the process. Please run the JVM with -XstartOnFirstThread. For offscreen rendering, make sure another window toolkit (e.g. AWT or JavaFX) is initialized before GLFW.

我在Intellij 2017.1.3中遇到了同样的错误; Mac OS 10.12.4; lwjgl-release-3.1
它解决了通过点击菜单-运行->编辑配置...然后将参数-XstartOnFirstThread添加到VM选项旁边的文本框中:
丝网印刷:x1c 0d1x的数据

对于缺少VM选项的用户,此字段将隐藏,如下所示:
运行->编辑配置... ->修改选项下拉菜单->添加VM选项-> -XstartOnFirstThread
x1c 0d1x的数据

你得到的异常非常清楚这个问题,你的
init()
方法调用glfwCreateWindow()
来创建GLFW Window
应该从main thread
调用。因此,将init()
方法设为公共,并删除run()
方法中的init();
调用。将你的main方法改为这样;字符串

如果您使用的是初始化器构建的build.gradle文件,则可以添加此部分,以指定Java命令行选项:
