[1.12.2] Is it still possible to programatically register recipes?


Recommended Posts

I assume I'm just doing something wrong here.  My test recipe shows up in NEI, but it doesn't show up in the recipe book and can't be crafted.  Here's the code:

  public static void registerRecipes(final RegistryEvent.Register<IRecipe> event) {
        new ShapelessRecipes(
            new ItemStack(Items.APPLE),
                Ingredient.fromStacks(new ItemStack(Items.CLAY_BALL)),
                Ingredient.fromStacks(new ItemStack(Blocks.SAND, 1, OreDictionary.WILDCARD_VALUE))
        ).setRegistryName(GradientMod.MODID, "recipe.tests")


For the record, I want to move some of my json recipes back to code because prior to 1.12, many recipes were automatically generated based on melting point, hardness, etc.  With json recipes, whenever I add a new cast/metal/tool/whatever I have to add quite a few files manually.



Was wildcard support removed from json recipes?  When I updated from 1.12 to 1.12.2, this recipe stopped working:

  "type": "minecraft:crafting_shapeless",
  "result": {
    "item": "gradient:clay_cast_unhardened",
    "data": 0
  "ingredients": [{
    "item": "minecraft:clay_ball"
  }, {
    "item": "minecraft:sand",
    "data": 32767


There were no other changes.  When data is changed from 32767 to 0, the recipe works (but obviously only supports regular sand).

You can yes, but you shouldn't. If you have all the data you need at compile time, then just generate the json files. 

As for your second question, we're looking into it, but due to how the recipe book works, you need to specify all sub-items in recipes.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Cool, that sounds like a good solution.  Thanks for the help.


For anyone else looking for an answer to the second question: until there's a better way, I just ended up defining a _constant called #SAND that includes sand with data 0 and 1.
