I am currently trying to create a custom registry and registering an entry using the deffered register system. 

 

Here is the building of my registry:

public static void registerRegistry(final RegistryEvent.NewRegistry e) {
    RegistryBuilder<CharacterClass> characterClassBuilder = new RegistryBuilder<>();
    characterClassBuilder.setType(CharacterClass.class);
    characterClassBuilder.setName(new ResourceLocation(Constants.MOD_ID, "character_classes"));
    characterClassBuilder.create();
    
    LogManager.getLogger(Constants.MOD_ID).debug("Created Character Class Registry");
}

 

The event listener is added in my mod constructer (here in line 4) and the registry objects are registered through the deferred register object CHARACTER_CLASS_REGISTRY in the CharacterClasses class

@Mod(Constants.MOD_ID)
public BlutmondRPG() {
    final IEventBus modBus = FMLJavaModLoadingContext.get().getModEventBus(); // Gets BlutmondRPG Event Bus
    modBus.addListener(CharacterClassRegistry::registerRegistry); //Register Character Class Registry <<<<<<<<<<
    modBus.addListener(this::setup); // Register Client & Server Event Handler
    modBus.addListener(this::clientSetup); // Register Client only Event Handler

    CharacterClasses.register(modBus);
}

 

CharacterClasses.class

private static final DeferredRegister<CharacterClass> CHARACTER_CLASS_REGISTRY = DeferredRegister.create(LazyForgeRegistry.of(CharacterClass.class), Constants.MOD_ID);
private static boolean isInitialised = false;
public static final RegistryObject<CharacterClass> DEFAULT_CLASS = CHARACTER_CLASS_REGISTRY.register("none", DefaultCharacterClass::new);

public static void register(final IEventBus modEventBus) {
    if (isInitialised) {
        throw new IllegalStateException("Already initialised");
    }
    CHARACTER_CLASS_REGISTRY.register(modEventBus);
    isInitialised = true;
    LogManager.getLogger(Constants.MOD_ID).debug("Registered Character Classes.");
}

 

those classes could be needed for understanding the whole code:

CharacterClass

LazyForgeRegistry

 

On startup i'm getting the NullPointerException from my LazyForgeRegistry ("Registry of type CharacterClass not present").

Somehow GameRegistry.findRegistry(CharacterClass.class) returns null.

Did i something wrong in my registerRegistry method?

Oh wow. This is a lot easier than i thought.

 

Thanks for your help!
