ShaderModuleData

[CapriciousSun]

When I tried to set ShaderModuleData as a record, it says that it must return a result of type record, instead of allowing me to keep it empty. Not to mention as a result, ShaderModuleData can't be resolved to a type in the constructor. Are you aware of this problem or is this something caused by my own incompetance.
This is what I wrote, I might have missed something

Hi, are you sure you are using a Java version which supoprt records? Which version are you using? The source code compiles ok, you can see even the results in Github workflow.

[CapriciousSun]

I am using SE-15

[lwjglgamedev]

I can't remember if Records were still a preview feature in Java 15. In any case, you will need Java 18 to compile the samples (this is stated in the first chapter). If you need to stay with Java 15 just check if you need to enable preview features or change records to plain classes. In any case you will face other problems I guess if you do not move to Java 18.

Am I allowed to use Java 19 or is that also going to cause conflicts

Oh and by the way this did solve my problem. Thank you for your time
