Register Entities in Forge 1.14

Posted October 8, 20196 yr

Hey, I'm trying to register an entity but the builder is painting it in red can someone help me?

EntityTypes Class:

package de.krokoyt.element.entity;

import de.krokoyt.element.Element.RegistryEvents;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityClassification;
import net.minecraft.entity.EntityType;
import net.minecraftforge.event.RegistryEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber.Bus;
import net.minecraftforge.registries.IForgeRegistry; 

@EventBusSubscriber(bus = Bus.MOD)
public class EntityTypes{ 
      
    public static EntityType<?> vampireball;
    
    @SubscribeEvent
    public static void register(RegistryEvent.Register<EntityType<?>> e) {
        IForgeRegistry<EntityType<?>> registry = e.getRegistry();
        vampireball = EntityType.Builder.create(Vampire::new, EntityClassification.CREATURE).build(""); 
        
        vampireball.setRegistryName("element", "vampire");
        registry.register(vampireball);
    }

}

Entity class:

package de.krokoyt.element.entity;

import de.krokoyt.element.Element;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityType;
import net.minecraft.entity.LivingEntity;
import net.minecraft.entity.item.EnderPearlEntity;
import net.minecraft.entity.projectile.ProjectileItemEntity;
import net.minecraft.entity.projectile.ThrowableEntity;
import net.minecraft.item.Item;
import net.minecraft.util.math.RayTraceResult;
import net.minecraft.world.World;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.api.distmarker.OnlyIn;

public class Vampire extends ThrowableEntity{

    
    
    protected Vampire(EntityType<? extends ThrowableEntity> type, World world) {
        super(type, world);
    }

    protected Vampire(EntityType<? extends ThrowableEntity> type, LivingEntity livingEntityIn, World worldIn) {
        super(type, livingEntityIn, worldIn);
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void onImpact(RayTraceResult result) {
        
        remove();
    }

    @Override
    protected void registerData() {
