How do i make an EntitySpawnEgg-class, that accepts a registry supplier?

Hello

 

Since someone told me, thar DeferredRegister is the best way to register mod-stuff, i want to register all my stuff tkis way.

 

Now i have a problem with SpawnEggs for Entities.

 

I registered an entity this way:

    public static final RegistryObject<EntityType<RedEntity>> RED = ENTITY_TYPES.register("red", () -> EntityType.Builder.create(RedEntity::new,
                        EntityClassification.AMBIENT).size(0.5F, 0.5F).build(null));

 

Someone sayd, to register the SpawnEgg also this way, a custom spawnegg-class, that accepts a supplyer, is needed.

I now tried it this way:

package drachenbauer32.angrybirdsmod.items;

import net.minecraft.entity.EntityType;
import net.minecraft.item.SpawnEggItem;
import net.minecraftforge.fml.RegistryObject;

public class SupplierSpawnEggItem extends SpawnEggItem
{   
    public SupplierSpawnEggItem(RegistryObject<EntityType<?>> supplierIn, int primaryColorIn, int secondaryColorIn, Properties builder)
    {
        super(supplierIn.get(), primaryColorIn, secondaryColorIn, builder);
    }
}

But now i get a n error about the constructor, that says:

Quote

The constructor SupplierSpawnEggItem(EntityType<RedEntity>, int, int, Item.Properties) is undefined

I cannot remove the name of the Entity-class here: RegistryObject<EntityType<RedEntity>> in the entity registerer, because this will cause some more errors, if i put a "?" instead.

How must i change the constructor, that it accepts theese suppliers, no matter, wich entity-class they contain?

Now i have this:

package drachenbauer32.angrybirdsmod.items;

import drachenbauer32.angrybirdsmod.entities.RedEntity;
import net.minecraft.entity.EntityType;
import net.minecraft.item.SpawnEggItem;
import net.minecraft.nbt.CompoundNBT;
import net.minecraftforge.fml.RegistryObject;

public class SupplierSpawnEggItem extends SpawnEggItem
{
    private RegistryObject<EntityType<?>> supplier;
    
    public SupplierSpawnEggItem(EntityType<?> typeIn, RegistryObject<EntityType<?>> supplierIn, int primaryColorIn, int secondaryColorIn, Properties builder)
    {
        super(typeIn, primaryColorIn, secondaryColorIn, builder);
        supplier = supplierIn;
    }
    
    @Override
    public EntityType<?> getType(CompoundNBT p_208076_1_)
    {
        return supplier.get();
    }
}

 

But i still don´t know how to change the RegistryObject-thing in the constructor to be able to pass RegistryObjets like

public static final RegistryObject<EntityType<RedEntity>> RED = ENTITY_TYPES.register("red", () -> EntityType.Builder.create(RedEntity::new,
                        EntityClassification.AMBIENT).size(0.5F, 0.5F).build(null));

or

public static final RegistryObject<EntityType<ChuckEntity>> RED = ENTITY_TYPES.register("chuck", () -> EntityType.Builder.create(ChuckEntity::new,
                        EntityClassification.AMBIENT).size(0.5F, 0.5F).build(null));

Wich have a specific entity-class in the inner "<>" instead of a "?" ?

 

They all have different Entity-classes there, and i need a solution, that allows them all to pass into this constructor.

public class SupplierSpawnEggItem extends SpawnEggItem
{
    private RegistryObject<?> supplier;
    
    public SupplierSpawnEggItem(EntityType<?> typeIn, RegistryObject<?> supplierIn, int primaryColorIn, int secondaryColorIn, Properties builder)
    {
        super(typeIn, primaryColorIn, secondaryColorIn, builder);
        supplier = supplierIn;
    }
    
    @Override
    public EntityType<?> getType(CompoundNBT p_208076_1_)
    {
        return (EntityType<?>) supplier.get();
    }
}

This works now.

In my inventory i have a normal looking spawn-egg, and i can plce the entity in the world with it.
