[1.16.4]NullPointerException when using registered custom features


QWERTY 52 38

Recommended Posts

Code repository: Here

 

I registered my custom feature in FeatureRegistry.java and McbbsWiki.java.

 

FeatureRegistry.java:

public static final DeferredRegister<Feature<?>> FEATURES = DeferredRegister.create(ForgeRegistries.FEATURES, "mcbbswiki");
public static RegistryObject<McbbsWikiLuckyBlockFeature> feature_lucky_block = FEATURES.register("feature_lucky_block", () -> new McbbsWikiLuckyBlockFeature(NoFeatureConfig.field_236558_a_));

 

McbbsWiki.java (the main class of this mod):

FeatureRegistry.FEATURES.register(
	FMLJavaModLoadingContext.get().getModEventBus()
);
 
But, when I used
FeatureRegistry.feature_lucky_block.get()

to get the object (in world.biome.McbbsWikiBiomeMaker.java:37), the game throwed a NullPointerException and crashed.

 

I found out "FeatureRegistry.feature_lucky_block.isPresent()" returned false and "FeatureRegistry.feature_lucky_block.value" is null, but do not know how to solve the problem.

 

The full logs are shown below.Please help me.
