Editing Tags

Making a Datapack

To add any kind of item, block or enchantment to their respective tags, you first need a Datapack.

There are a multitude of tutorials you can watch, but I recommend this one by Legitimoose.

Actually Editing Tags

The Basics

All Quad tags are under the "name space" of quad:. Create a folder called tags, making a path of data/quad/tags/. In the tags folder you can create the respective folders for what you wish to add.

• For block tags create a folder called blocks - for 1.21+ this is now block
• For item tags create a folder called items - for 1.21+ this is now item
• For enchantment tags create a folder called enchantment

When you see a / slash in a path, it means its a new folder, tag files will only contain letters, numbers or _ underscores, and anything before a : colon would be the "name space" (e.g. quad:<tag_path>)

example_tag.json

{
  "replace": false,
  "values": [
    "minecraft:example_item_1",
    "minecraft:example_item_2"
  ]
}

Here is an example_tag. Find a tag you want to edit in #List of Tags, I will choose immune/fire. For my tag, immune/ is another folder, so we need to create that in quad/tags/items. When in the correct path, create a new file, name it the tag you wish (in my case fire) and end it with .json. This is important.

Hover over the example_tag code and you should see a copy button, paste it into the new file.

minecraft: is the "name space" or "mod id", and example_item is the "item id". For items and blocks you can see the "name space" and "item id" in the inventory with advanced tooltips (shown with f3 + h). For enchantments, the "item id" is (usually) the name, e.g. minecraft:fire_aspect. (you can see the full list of enchantments with /enchant @s)

Each new value needs to be seperated with a , comma, with the last value ending without one.

More Advanced

Remove the line "replace": false, to remove any other mods/datapacks adding items to the tag, only items in your file will be applied.

Adding items in other tags can be done by putting a # hashtag before the "name space", e.g. #minecraft:planks. However, usually you would want to add a little extra safety with adding other tags.

example_tag_2.json

{
  "replace": false,
  "values": [
    {
      "id": "#minecraft:example_tag",
      "required": false
    },
    "minecraft:example_item_3",
    "minecraft:example_item_4"
  ]
}

With this, example_item from 1-4 will have the tag, 1-2 loaded from the first example_tag. If for any reason example_tag doesn't exist or has an error, example_item, 3 and 4 will still be loaded into the tag and example_tag will be ignored.
