I seem to be overlooking something as I am getting an error I'm not sure how to fix, as I thought I did it correctly.

public class EntityInit {
    private static final DeferredRegister<EntityType<?>> ENTITIES = DeferredRegister.create(ForgeRegistries.ENTITIES, PrimitiveStart.MODID);

    public static void initialize() {
        ENTITIES.register(FMLJavaModLoadingContext.get().getModEventBus());
    }

    public static final RegistryObject<EntityType<BoneArrow>> BONE_ARROW = ENTITIES.register("bone_arrow",
            () -> EntityType.Builder
                    .of(BoneArrow::new, MobCategory.MISC)
                    .sized(0.5F, 0.5F)
                    .clientTrackingRange(4)
                    .updateInterval(20)
                    .build(new ResourceLocation(PrimitiveStart.MODID, "bone_arrow").toString())
    );
}

Above code seems to have the following problem:

This is the BoneArrow class in question:

public class BoneArrow extends AbstractArrow {

    public BoneArrow(EntityType<? extends AbstractArrow> p_36721_, Level p_36722_) {
        super(p_36721_, p_36722_);
    }

    public BoneArrow(LivingEntity p_36718_, Level p_36719_) {
        super(EntityInit.BONE_ARROW.get(), p_36718_, p_36719_);
    }

    @Override
    protected ItemStack getPickupItem() {
        return new ItemStack(ItemInit.BONE_ARROW.get());
    }
}

Any help is appreciated.

there is no matching constructor in your Entity class, use your IDE to create the correct constructor 

Edited April 26, 20223 yr by Luis_ST

That sadly doesn't work, as it wants this constructor (bottom constructor):

It should use the top contructor, which it does when I remove the second one:

However, I need the second constructor, because it is used in the createArrow method:

Any ideas as to why it is doing this?

That worked, thank you!
