How to make a custom boat?

[JCS-Mecabricks]

I am making new wood types for Neoforge 1.21.4 but I can't make a boat. Do you have any instructions how?

For reference, having a WoodType is not a requirement for making a boat. Additionally, I will assume you don't want to change the model or anything outside of what vanilla already does.

Basically, a boat comes down to two things: the item and its entity, both of which already have classes you could just use. The entity does hold a reference to the item and vice versa, so just know you will need to create both in tandem.

For the item:

• Register a new BoatItem, passing in your entity type explained below.
  • If you want to match the boat directly, see Items#OAK_BOAT as they are all exactly the same.
• Add the item to the minecraft:boats tag.
• Register a new BoatDispenseItemBehavior for the item via DispenserBlock#registerBehavior within FMLCommonSetupEvent#enqueueWork on the mod event bus by passing in the entity type explained below.

For the entity:

• Register a new entity type, using Boat as the factory, passing in your item explained above.
  • If you want to match directly, see EntityType#OAK_BOAT as they are all exactly the same.
• Add the entity type to the minecraft:boat tag.
• Create a new ModelLayerLocation for the boat, making sure that you provide your own namespace and path
  • This location will be used to find the texture at assets/<namespace>/textures/entity/<path>.png
• Create a new LayerDefinition for the ModelLayerLocation using BoatModel#createBoatModel via RegisterLayerDefinitions#registerLayerDefinition on the mod event bus.
• Register a new BoatRenderer for your entity type by passing in the ModelLayerLocation via RegisterRenderers#registerEntityRenderer.

If you wish to change certain aspects, you can subclass or replace as necessary. You can also follow the codebase within vanilla as nothing is particularly hardcoded for a simple implementation.

I tried making the entity type but the constructor won't match.

You will need to provide more information as the constructor won't match is not clear. When passing the entity type to the builder, you will need to do something similar to (type, level) -> new Boat(type, level, <supplier item>) similar to how the vanilla entity types do.

is this okay? package github.jcsmecabricks.redwoodvariants.entity.custom;

import net.minecraft.world.entity.EntityType;
import net.minecraft.world.entity.vehicle.Boat;
import net.minecraft.world.item.Item;
import net.minecraft.world.level.Level;

import java.util.function.Supplier;

public class ModBoatEntity extends Boat {
public ModBoatEntity(EntityType<? extends Boat> p_376173_, Level p_38293_, Supplier p_376917_) {
super(p_376173_, p_38293_, p_376917_);
}
}

You can also just use the normal Boat class instead of subclassing. Subclassing is only required is if you intend to override a method in the boat entity. Also, the Supplier should specify its generic as the Item form of the entity.

How should I register it in the entity layers? Can you write the code?

[ZestyBlaze]

If we write the code for you, you won't learn as well. Honestly your best bet is going to 'Items.OAK_BOAT` and have a look how vanilla do it, as of 1.21.4 it's the same for nodded too I believe. You can do the same as they do

Ok. Thanks for the advice.
