Minecraft 1.13 Snapshot 17w49a changes sticky pistons and introduces a new feature called tags.

Minecraft 1.13 Snapshot 17w49a

Features:

  • Tags: Items & blocks can be “tagged” with an ID, to make testing for things much easier. For example, checking if a block is “wool” with a command needs to actually test for every wool-like block individually. Now you can test if it matches the tag minecraft:wool, instead.
  • Types of Tags: Currently there’s block tags and item tags. You use block tags when testing for blocks in the world, and item tags for testing for items (even block-items) in inventories. It may seem like we could just stick with item tags, but not every block has an item!
  • Creating Tags: Inside data packs, you can create a file at data/(namespace)/tags/blocks/foo.json to make a block tag called namespace:foo, which contains a list of blocks that should be tagged with namespace:foo.
  • Recipes: Recipes can now refer to a tag instead of an item. This should save a few hundred thousand lines of code, somewhere.
