出现此错误的原因是因为您在一个单独的线程上运行GLFW窗口。在主线程上运行窗口,它就可以工作了。
正如在这里的评论中读到的
做了快速检查。在同一个程序中创建多个显示会导致错误,即使它们是在分开的线程中创建的。您可以做的一件事是为您需要的两个(或更多)显示创建分离的java程序,并让它们使用套接字和/或流进行通信
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
给定Clojure的并发模型,我如何确保所有LWJGL OpenGL更新函数都是从同一个线程调用的? 我熟悉C/C++中的线程。我熟悉Clojure的agent/atom/ref模型。然而,我并不熟悉Clojure中的“手动”并发/线程处理。 谢谢!
我的程序中运行了两个线程。当我尝试在非主线程中使用OpenGL函数时,它抛出了一个IllegalStateException:当前线程中没有当前的OpenGL上下文。所以我的问题是,如何将上下文从主线程传递到另一个线程?我正在使用LWJGL 3。
我试图用Java/LWJGL做一个简单的游戏。我在学习一个在windows上制作的教程,我用的是Mac。我复制了他的代码来打开一个窗口字符,程序立即崩溃了,给了我一个很长很奇怪的错误,可能与指针有关(我实际上不知道)。下面是用于创建窗口的行,我使用该窗口的属性中定义了宽度和高度: 当我在mac上运行它时,它会给我以下错误:
我在Android上使用RxJava和Retrofit2.0来处理网络请求。 在创建可观察对象时,我向其添加以下内容: 是否有一个优雅的解决方案来解决这个问题,而不必手动地用一个块包装我的实现,以便将一些东西发布到主线程?
我今天下载了LWJGL3,发现它几乎完全重写了。我查阅了一个关于如何创建窗口的教程,但我仍然有创建窗口的问题。 代码运行时没有问题:控制台中没有错误,但窗口没有显示!
