请帮帮我。我从https://libgdx.badlogicgames.com/tools.html下载了jar文件它是runnable-2D-particles.jar 当我运行它时，打开程序无法使用。 Nope字段渲染，所有块都是空的。

登录控制台：

P.S。已安装视频驱动程序。我该如何解决这个问题？我使用WIN10，jdk1.8.0_51，jre1.8.0_60（如果重要的话）

Answer 1

问题在于OpenGL，因为com.badlogic.gdx.backends.lwjgl.LwjglGraphics.createDisplayPixelFormat(LwjglGrap‌hics.java:320) LwjglGraphics行OpenGL is not supported by the video driver的{{1}}说for /F "tokens=*" %%A in ('netsh wlan show interface ^| find "SSID : SSID Name"') do ( for /F "tokens=2*" %%I in ('netsh wlan show interface ^| find "Name"') do ( netsh wlan set profileorder name="SSID Name" interface="%%J" priority=1 ) )。
因此，您应该检查您的卡是否至少支持OpenGL 1.5，如果是，请更新您的视频卡驱动程序。
