Java 使用OpenGL ES 3.0的当前线程LWJGL中没有当前的OpenGL ES上下文
我试图使用入门示例(来自{which unchanged works fine})使用LWJGL,但对其进行了修改,使其使用OpenGL ES 3.0(原因与此问题无关) 我使用最新的LWJGL版本3.1.1,选择最小的OpenGL ES作为我的预设(从),并使用windows本机。(我正在运行Windows 10 64位) 我被卡住了--我不知道如何修复它,如何让它运行 我得到的错误是: 线程“main”java.lang.IllegalStateException中的异常:当前线程中没有当前的OpenGL ES上下文。 完全错误:Java 使用OpenGL ES 3.0的当前线程LWJGL中没有当前的OpenGL ES上下文,java,lwjgl,Java,Lwjgl,我试图使用入门示例(来自{which unchanged works fine})使用LWJGL,但对其进行了修改,使其使用OpenGL ES 3.0(原因与此问题无关) 我使用最新的LWJGL版本3.1.1,选择最小的OpenGL ES作为我的预设(从),并使用windows本机。(我正在运行Windows 10 64位) 我被卡住了--我不知道如何修复它,如何让它运行 我得到的错误是: 线程“main”java.lang.IllegalStateException中的异常:当前线程中没有当前

是否值得注意。。。如果我取消注释:
import org.lwjgl.opengl.*;
import org.lwjgl.opengl.*;
以及,改变:
GLES.createCapabilities();
并且,请使用以下选项:
GL.createCapabilities();
我得到这个错误:
线程“main”java.lang.IllegalStateException中的异常:未为当前线程设置GLESCapabilities实例。可能的解决方案:设法找到解决方案(从) 我取消注释:
import org.lwjgl.opengl.*;

在init()函数中调用glfwCreateWindow函数之前,添加了:
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0);
glfwWindowHint(GLFW_CLIENT_API, GLFW_OPENGL_ES_API);
并且,在init()函数的末尾添加了以下内容:
// Bypasses the default create() method.
Configuration.OPENGLES_EXPLICIT_INIT.set(true);
GLES.create(GL.getFunctionProvider());
这是因为它使用了org.lwjgl.opengles.GL函数地址,而不是org.lwjgl.opengles.GLES。在Windows上,它们使用OpenGL本机函数地址,但不考虑(有些例外)
