Question

当我在Thinmatrix上关注java lwjgl 2.9 3D游戏教程的教程时。我遇到了烦人的问题（陷入ep16：迷雾）：Docker Toolbox + Minikube + Kubectl

我检查了我的代码2次仍然抛出异常，我不知道该怎么办只是不能。

非常感谢任何帮助。

编辑：如果您需要更多代码，请对其进行评论。

在TerrainFragmentShader中，您在可见性

后缺少分号

#version 400 core

in vec2 pass_textureCoordinates;
in vec3 surfaceNormal;
in vec3 toLightVector;
in vec3 toCameraVector;
in float visibility //<-semicolon here
