Tags

From Forge Community Wiki

Tags are generalized sets of objects in the game, used for grouping related things together and providing fast membership checks.

Declaring Your Own Groupings

Tags are declared in your mod’s datapack. For example, a TagKey<Block> with a given identifier of modid:foo/tagname will reference a tag at /data/<modid>/tags/blocks/foo/tagname.json. Tags for Blocks, Items, EntityTypes, Fluids, and GameEvents use the plural forms for their folder location while all other registries use the singular version (EntityType uses the folder entity_types while Potion would use the folder potion). Similarly, you may append to or override tags declared in other domains, such as Vanilla, by declaring your own JSONs. For example, to add your own mod’s saplings to the Vanilla sapling tag, you would specify it in /data/minecraft/tags/blocks/saplings.json, and Vanilla will merge everything into one tag at reload, if the replace option is false. If replace is true, then all entries before the json specifying replace will be removed.

Values listed that are not present will cause the tag to error unless the value is listed using an id string and required boolean set to false, as in the following example:

{
  "replace": false,
  "values": [
    "minecraft:gold_ingot",
    "mymod:my_ingot",
    {
      "id": "othermod:ingot_other",
      "required": false
    }
  ]
}

See the Vanilla wiki for a description of the base syntax.


There is also a Forge extension on the Vanilla syntax. You may declare a remove array of the same format as the values array. Any values listed here will be removed from the tag. This acts as a finer grained version of the Vanilla replace option.

Using Tags In Code

Tags for all registries are automatically sent from the server to any remote clients on login and reload. Blocks, Items, EntityTypes, Fluids, and GameEvents are special cased as they have Holders allowing for available tags to be accessible through the object itself.

Tags wrappers can be created using TagKey#create where the registry the tag should belong to and the tag name are supplied. Some vanilla defined helpers are also available to create wrappers via *Tags#create where * refers to the name of the registry object. Forge wrapped registries can create a tag using ITagManager via IForgeRegistry#tags. TagKeys can then be obtained via ITagManager#createTagKey.

Forge wrapped registry objects can grab their associated holder using IForgeRegistry#getHolder. Additionally, other streamlined operations can be performed using ITagManager. Non-Forge registry objects use either Registry#getHolder or Registry#getHolderOrThrow to get the current holder.

They then can compare if the registry object has a tag using Holder#is. Tag-holding registry objects contain a method called #is in either their registry object or state-aware class to check whether the object belongs to a certain tag.

As an example:

public static final TagKey<Item> myItemTag = ItemTags.create(new ResourceLocation("mymod", "myitemgroup"));

public static final TagKey<Potion> myPotionTag = ForgeRegistries.POTIONS.tags().createTagKey(new ResourceLocation("mymod", "mypotiongroup"));

public static final TagKey<VillagerType> myVillagerTypeTag = TagKey.create(Registry.VILLAGER_TYPE, new ResourceLocation("mymod", "myvillagertypegroup"));

// In some method where stack is an ItemStack
boolean isInItemGroup = stack.is(myItemTag);

// In some method where potion is a Potion
boolean isInPotionGroup = ForgeRegistries.POTIONS.tags().getTag(myPotionTag).contains(potion);

// In some method where villagerTypeKey is a ResourceKey<VillagerType>
boolean isInVillagerTypeGroup = Registry.VILLAGER_TYPE.getHolder(villagerTypeKey).map(holder -> holder.is(myVillagerTypeTag)).orElse(false);

Migration from OreDictionary

  • For recipes, tags can be used directly in the vanilla recipe format (see below)
  • For matching items in code, see the section above.
  • If you are declaring a new type of item grouping, follow a couple naming conventions:
    • Use domain:type/material. When the name is a common one that all modders should adopt, use the forge domain.
    • For example, brass ingots should be registered under the forge:ingots/brass tag, and cobalt nuggets under the forge:nuggets/cobalt tag.

Using Tags in Recipes and Advancements

Tags are directly supported by Vanilla, see the respective Vanilla wiki pages for recipes and advancements for usage details.

Conventions

There are several conventions that will help facilitate compatibility in the ecosystem:

  * If there is a Vanilla tag that fits your block or item, add it to that tag. See the list of Vanilla tags. 
  * If there is a Forge tag that fits your block or item, add it to that tag. The list of tags declared by Forge can be seen on GitHub. 
  * If there is a group of something you feel should be shared by the community, consider PR-ing it to Forge instead of making your own tag 
  * Tag naming conventions should follow Vanilla conventions. In particular, item and block groupings are plural instead of singular. E.g. minecraft:logs, minecraft:saplings. 
  * Item tags should be sorted into subdirectories according to the type of item, e.g. forge:ingots/iron, forge:nuggets/brass, etc.

Forge Tags

This is a list of all tags using the forge namespace that are currently defined by Forge along those that are commonly used by other mods. These can all be found within the Tags class.

Important

Tags that are not officially defined within the Forge codebase will have * as a suffix. To use those outside the Forge codebase, an IOptionalNamedTag must be created using *Tags#createOptional where the asterisk can be replaced by its associated class name.
