      How do I make a drink item?

      By DroidCrafter23 · Posted

      Thank you so, so much for your help! I have implemented the code from the example you gave me and it has been excepted, the only downside currently being that the game crashes on launch, saying:  Caused by: java.lang.IllegalStateException: Cannot register new entries to DeferredRegister after RegisterEvent has been fired.  (Three times) and  Caused by: java.lang.ExceptionInInitializerError (Two times) With further scanning I have found this error: 2024-05-05T18:41:24.287+0100 [ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter] I am not exactly sure what to do with these errors but I am sure I can resolve them. Once again, thank you for your help! It is much appreciated. 😁
