使用JMonkeyEngine，我创建了一个非常简单的SimpleApplication子类，但是我得到一个非常奇怪的错误，不知道是什么导致它。更重要的是，这曾经工作得很好，但似乎我的系统上发生了一些破坏它的事情。新工作区在同事的计算机上运行此代码就好了。
我收到一条'bad compile'消息，打印出Common / ShaderLib / Skinning.glsllib和Common / MatDefs / Misc / Unshaded.vert文件的串联。 （作为预处理器复制粘贴的结果）。
错误说我错过了文件顶部的'#version'。当然，我没有更改文件。我的理解是GLSL编译器应该将没有指定版本的文件解释为版本110。
第二个抱怨是关于“属性”第76行的语法错误。我没有看到任何错误。
我已尝试通过AppSettings指定要使用的OpenGL版本，但这似乎没有效果。
当我通过调试器运行代码时，我看到有一个字符串'language'设置为“GLSL100”，但是int'版本'设置为150.这是在LwjglRenderer中。

这是我的代码：
import com.jme3.app.SimpleApplication;
public class VerySimpleApplication
extends SimpleApplication
{
@Override
public void simpleInitApp()
{
// TODO Auto-generated method stub
}
public static void main(String[] args)
{
VerySimpleApplication app = new VerySimpleApplication();
app.start();
}
}
答案 0 :(得分：0)
好的，问题是我需要使用OpenGL 2时默认使用OpenGL 3.
VerySimpleApplication app = new VerySimpleApplication();
AppSettings settings = new AppSettings(true);
settings.setRenderer(AppSettings.LWJGL_OPENGL2);
app.setSettings(settings);
app.start();
