Additions

General

Minecraft:Tags

• Items and blocks can now be "tagged" with an ID.
  • Block tags can be used when testing for blocks in the world.
  • Items tags can be used when testing for items in inventories.
• Tags are created using Minecraft:data packs in data/(namespace)/tags/blocks or data/(namespace)/tags/items.
  • For example: data/(namespace)/tags/blocks/foo.json.
  • This creates a block tag called (namespace):foo.
  • The json file contains a list of all blocks that should be "tagged".
• There are two default tags for both the item form and the block form: minecraft:wool for all wool blocks and minecraft:planks for all wood plank blocks.

Changes

General

Crafting

• Recipes can now refer to a tag instead of an item.
