Problem with custom tags


Hive Mind

Recommended Posts

I've been trying to create custom tags for items in the mod I am making so any future recipes I add can use items with ore dictonary tags instead of specific items, but I've run into a problem. I already have a recipe that uses oredict tags rather than items but when I try to load into a world to test if it works the game says:

"Errors in currently selected datapacks prevented the world from loading. You can either try to load it with only the vanilla datapack ("safe mode"), or go to the title screen and fix it manually."

It seems as, despite the TagInit class being free of errors, the tags I have created doesn't exist (?). I've been following a 1.18.1 modding tutorial that explained how to create custom tags, but I am making a mod in 1.18.2 and I've heard that tags went through some changes between those versions and I guess the problems lay there. I've triple-checked that I got the namespaces and tag names right.

Below is the TagInit class, two of the tag json files and the recipe that uses said tags.

TagInit class:

package com.hivemind.superheated.init;

import com.hivemind.superheated.Superheated;

import net.minecraft.resources.ResourceLocation;
import net.minecraft.tags.BlockTags;
import net.minecraft.tags.ItemTags;
import net.minecraft.world.item.Item;
import net.minecraft.world.level.block.Block;
import net.minecraft.tags.TagKey;


public final class TagInit {
	
	public static final class Blocks {
		
		public static final TagKey<Block> BLOCK_CRUDE_STEEL = mod("blockCrudeSteel");
		
		private static TagKey<Block> mod(String path) {
			return BlockTags.create(new ResourceLocation(Superheated.MOD_ID, path));
		}
	}
	
	public static final class Items {
		
		public static final TagKey<Item> INGOT_CRUDE_STEEL = mod("ingotCrudeSteel");
		public static final TagKey<Item> BLOCK_CRUDE_STEEL = mod("blockCrudeSteel");
		public static final TagKey<Item> PLATE_IRON = mod("plateIron");
		public static final TagKey<Item> LIGHT_PLATE_IRON = mod("lightPlateIron");
		
		private static TagKey<Item> mod(String path) {
			return ItemTags.create(new ResourceLocation(Superheated.MOD_ID, path));
		}
	}
}

The custom tags and thier names:

blockCrudeSteel.json

{
	"replace": false,
	"values": [
		{
			"id": "superheated:block_crude_steel"
		}
	]
}

plateIron.json

{
	"replace": false,
	"values": [
		{
			"id": "superheated:plate_iron"
		}
	]
}

The recipe:

{
	"type": "minecraft:crafting_shaped",
	"pattern": [
		"AAA",
		"BCB",
		"DDD"
	],
	"key": {
		"A": {
			"tag": "superheated:blockCrudeSteel"
		},
		"B": {
			"tag": "superheated:plateIron"
		},
		"C": {
			"item": "minecraft:anvil"
		},
		"D": {
			"item": "minecraft:polished_deepslate"
		}
	},
	"result": {
		"count": 1,
		"item": "superheated:forging_anvil"
	}
}

Errors in currently selected datapacks prevented the world from loading.

What is the actual error in your run/logs/latest.log? Probably a parsing error or something not found.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.
