Copied your code but got his error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException at engineTester.MainGameLoop.main(MainGameLoop.java:12) Caused by: java.lang.ClassNotFoundException: org.lwjgl.LWJGLException at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:636) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:182) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:519) ... 1 more

I also tried adding the main method in DisplayManager.class for debugging purposes but got this:

Error: Unable to initialize main class renderEngine.DisplayManager Caused by: java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException

@UjjwalGupta-Git, which version of LWJGL are you using? It seems it is a NoClassDefFoundError which means that you might be using the wrong version of LWJGL or you might have added the libs incorrectly. watch this tutorial and make sure you are listening to what TheThinMatrix said. Your folder/package directory may also be causing this. I have not tried it yet myself though which means I may be wrong. Also, refer to this stackoverflow post and make sure your ide or text editor is configuring the build time and runtime classpaths correctly. The runtime classpath is most likely what is causing the error.

The link in the description of your unlisted video led me to a page that automatically downloads LWJGL-2.9.1.zip

[abhay7dev]

ok, once you downloaded that, did you add the jars the zip provided?

[UjjwalGupta-Git]

Yes

[abhay7dev]

Then I am not sure, sorry.

[UjjwalGupta-Git]

No worries I will figure it out somehow, I always do.🙂

For future readers: I had this issue as well, you have to put your jars under "Classpath" instead of "Modulepath"

@CMDR-Piboy314 but then i can not access classes

[Piras314]

@Tanu257 oh? It worked just fine for me...
