Patzlyk · Answer 5 · 2019-07-11T11:55:08.000Z

Oh, this is in runtime. assumed it was in a dev environment, my bad.

Patzlyk · Answer 8 · 2019-07-11T12:30:55.000Z

I get this error in dev environment, I tried to run the game.

Blayyke · Answer 9 · 2019-07-11T12:32:03.000Z

Got the word wrong, I meant that I thought it was an error showing up during compilation before even getting the game to run

Patzlyk · Answer 10 · 2019-07-11T12:36:44.000Z

I get the error before i start debugging.

Blayyke · Answer 11 · 2019-07-11T12:37:28.000Z

Can you send the all the lines of the class?

Patzlyk · Answer 12 · 2019-07-11T12:38:21.000Z

This is the entire file:

package net.fabricmc.example;

import java.rmi.registry.Registry;

import net.fabricmc.api.ModInitializer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemGroup;
import net.minecraft.util.Identifier;
import net.minecraft.util.registry.*;
import net.fabricmc.fabric.api.registry.*;
import net.fabricmc.fabric.impl.registry.*;

public class ExampleMod implements ModInitializer
{
    // an instance of our new item
    public static final Item FABRIC_ITEM = new Item(new Item.Settings().group(ItemGroup.MISC));
 
    @Override
    public void onInitialize()
    {
        Registry.register(Registry.ITEM, new Identifier("tutorial", "fabric_item"), FABRIC_ITEM);
    } 
}

Blayyke · Answer 13 · 2019-07-11T12:39:05.000Z

import java.rmi.registry.Registry; yep, another registry import as i thought. try it without this line.

Patzlyk · Answer 14 · 2019-07-11T12:45:19.000Z

It works now, thanks.

UrLostPajamas · Answer 15 · 2020-08-02T01:38:42.000Z

a whole year+ later this still solves this issue lol

shedaniel · Answer 16 · 2020-08-02T06:08:47.000Z

this isn't an issue on fabric's end, it's just the issue that you have imported and used the wrong Registry.
