提示 标签事件是服务端事件。 提示 标签按物品/方块/流体/实体类型划分，因此无法基于 NBT 数据等条件来添加标签！

标签事件有一个额外参数，用于决定将标签添加到哪个注册表。你通常只需要物品、方块和流体标签。不过，它也支持向任何注册表添加标签，包括其他模组的注册表。如果是模组的注册表，请确保包含命名空间！

// Listen to item tag event
ServerEvents.tags('item', event => {
  // Get the #forge:cobblestone tag collection and add Diamond Ore to it
  event.add('forge:cobblestone', 'minecraft:diamond_ore')

  // Get the #forge:cobblestone tag collection and remove Mossy Cobblestone from it
  event.remove('forge:cobblestone', 'minecraft:mossy_cobblestone')

  // Get #forge:ingots/copper tag and remove all entries from it
  event.removeAll('forge:ingots/copper')

  // Required for FTB Quests to check item NBT
  event.add('itemfilters:check_nbt', 'some_item:that_has_nbt_types')

  // You can create new tags the same way you add to existing, just give it a name
  event.add('forge:completely_new_tag', 'minecraft:clay_ball')

  // It supports adding tags to tags as well. Just prefix the second tag with #
  event.add('c:stones', '#forge:stone')

  // Removes all tags from this entry
  event.removeAllTagsFrom('minecraft:stick')

  // Add all items from the forge:stone tag to the c:stone tag, unless the id contains diorite
  const stones = event.get('forge:stone').getObjectIds()
  const blacklist = Ingredient.of(/.*diorite.*/)
  stones.forEach(stone => {
    if (!blacklist.test(stone)) event.add('c:stone', stone)
  })
})

提示 配方使用物品标签，而不是方块或流体标签。即使代表这些内容的物品是方块（如 minecraft:cobblestone），配方依然使用物品标签。

// Listen to the block tag event
ServerEvents.tags('block', event => {
  // Add tall grass to the climbable tag. This does make it climbable!
  event.add('minecraft:climbable', 'minecraft:tall_grass')
})
