[1.14.4] Questions about recipes, advancements and tags

[yolp900 0]

I have a few questions about the crafting system, advancement system and tag system:

 

1. The crafting system: I'm using ShapedRecipeBuilder and ShapelessRecipeBuilder. Say I want to have two different crafting recipes for the same item - How would one do so? Is there an example in vanilla which I missed?

2. About the advancement system: I'm using .addCriterion with InventoryChangeTrigger.Instance.forItems to add a list of items which are needed for the craft. However this only allows a list of items. Is there a way to use tags? i.e. whenever the player has items from the relevant tags - the crafting recipe will be exposed (as opposed to specific items).

3. The new tag system: Is there a convention about adding tags - Which tags are common (other than the given tags in forge), how tags are supposed to be added (I'm extending BlockTagsProvider and ItemTagsProvider from vanilla, is there a way to do so from Forge which I haven't found?). For example, I expected there would be a tag for paper. If I were to add a paper equivalent and wanted recipes to use it too, what should I do?

 

I think theses are general questions which don't need code samples, but just in case here is an example of how I register a recipe:

ShapedRecipeBuilder.shapedRecipe(ModItems.SPELL_PARCHMENT)
                .patternLine(" B ")
                .patternLine("PPP")
                .patternLine(" B ")
                .key('B', ModItemTagsProvider.BINDING_REAGENT)
                .key('P', Items.PAPER)
                .setGroup(Spellies.MOD_ID + "." + SpellParchment.REGISTRY_NAME)
                .addCriterion(SpellParchment.REGISTRY_NAME, InventoryChangeTrigger.Instance.forItems(ModItems.LIGHT_BINDING_REAGENT, Items.PAPER, ModItems.DARK_BINDING_REAGENT))
                .build(consumer);

Make two recipe files

Use the json system?

  "criteria": {
    "has_planks": {
      "trigger": "minecraft:inventory_changed",
      "conditions": {
        "items": [
          {
            "tag": "minecraft:planks"
          }
        ]
      }
    },

You don't need to do that. Just create the json file and call BlockTags/ItemTags.getCollection().getOrCreate(...)

Its right there in the docs.
