I am making a mod that adds a new fishing rod for catching other fish like swordfish or shark in 1.12.2. I finish making the class for the rod and there is an error. The error says, "Implicit super constructor ItemBase() is undefined. Must explicitly invoke another constructor." I'm fairly new to modding so I don't know what to do. The code is below. Someone help. The error is on this line:

 

public DeepSeaRod(String name) {

ItemBase is the class you extended for your fishing rod class, can you post what your ItemBase class looks like so we can see what's wrong with it?

Do not use ItemBase. Read the Common issues and recommendations for more explanation.

The ItemBase class is basically pointless, and makes you write redundant code.

package com.tabulate.aquaticfoods.objects.items;

import com.tabulate.aquaticfoods.Main;
import com.tabulate.aquaticfoods.init.ItemInit;
import com.tabulate.aquaticfoods.util.IHasModel;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.Item;

 

public class ItemBase extends Item implements IHasModel{

    public ItemBase(String name) {
        setUnlocalizedName(name);
        setRegistryName(name);
        setCreativeTab(Main.aquaticfoodstab);
        
        ItemInit.ITEMS.add(this);
    }

    @Override
    public void registerModels() {
        Main.proxy.registerItemRenderer(this, 0, "inventory");
    }

}
 

And this is IHasModel:

 

 

 

package com.tabulate.aquaticfoods.util;

 

public interface IHasModel {
    
    public void registerModels();

}

If you’re following a tutorial right now, stop. It’s making you write bad code that you will need to remove later.

Ok, I will.I don't like what he's doing, but I think it's literally the only tutorial on how to make a fishing rod lol

See this? This is your constructor.

See this? It does not call super. This means it calls public ItemBase() implicitly. Which is a function that does not exist.

 

There's your problem. But as Cadiboo already stated, you don't need ItemBase, that class already exists, its called Item.
