[1.15.2] Custom shapeless crafting RecipeWrapper

[proxyAlice]

 

I am working on a mod that adds a crafting station with five input slots and one output slot. I want to implement a new crafting type so that I can create shapeless recipes for use with this block, but that cannot be crafted in any other table.

 

I found this example that was shared by someone on a different thread that helped me get started setting up the IRecipe and Serializer. Im not totally sure, but it seems to me like this recipe type takes a single input and produces output from looking at the matches() function, but I could be understanding it wrong. My block also will have no ticks/processing time so I removed that. 

 

Here is my recipe class so far

public class BdoCookingRecipe implements IRecipe<RecipeWrapper> {


    private final ResourceLocation id;
    private final String group;
    private final NBTIngredient original;
    private final ItemStack result;

    public BdoCookingRecipe(ResourceLocation id, String group, NBTIngredient original, ItemStack result) {
        this.id = id;
        this.group = group;
        this.original = original;
        this.result = result;
    }

    @Override
    public boolean matches(RecipeWrapper inv, World worldIn) {
        return this.original.test(inv.getStackInSlot(0));
    }

    @Override
    public ItemStack getCraftingResult(RecipeWrapper inv) {
        return this.result.copy();
    }

    @Override
    public boolean canFit(int width, int height) {
        return true;
    }

    @Override
    public ItemStack getRecipeOutput() {
        return this.result;
    }

    @Override
    public ResourceLocation getId() {
        return this.id;
    }

    @Override
    public String getGroup() {
        return this.group;
    }

    @Override
    public NonNullList<Ingredient> getIngredients() {
        return NonNullList.withSize(1, this.original);
    }

    @Override
    public NonNullList<ItemStack> getRemainingItems(RecipeWrapper inv) {
        return NonNullList.create();
    }

    @Override
    public ItemStack getIcon() {
        return new ItemStack(RegistryHandler.BASIC_COOKING_UTENSIL_BLOCK.get());
    }

    @Override
    public IRecipeSerializer<?> getSerializer() {
        return ModRecipes.BDOCOOKING.get();
    }

    @Override
    public IRecipeType<?> getType() {
        return ModRecipes.Type.BDOCOOKING;
    }

    public static class Serializer extends ForgeRegistryEntry<IRecipeSerializer<?>> implements IRecipeSerializer<BdoCookingRecipe> {

        @Override
        public BdoCookingRecipe read(ResourceLocation recipeId, JsonObject json) {
            String group = JSONUtils.getString(json, "group", "");
            NBTIngredient ingredient = NBTIngredient.Serializer.INSTANCE.parse(JSONUtils.getJsonObject(json, "ingredient"));
            ItemStack result = CraftingHelper.getItemStack(JSONUtils.getJsonObject(json, "result"), true);
            return new BdoCookingRecipe(recipeId, group, ingredient, result);
        }

        @Override
        public BdoCookingRecipe read(ResourceLocation recipeId, PacketBuffer buffer) {
            String group = buffer.readString(32767);
            NBTIngredient ingredient = NBTIngredient.Serializer.INSTANCE.parse(buffer);
            ItemStack result = buffer.readItemStack();
            return new BdoCookingRecipe(recipeId, group, ingredient, result);
        }

        @Override
        public void write(PacketBuffer buffer, BdoCookingRecipe recipe) {
            buffer.writeString(recipe.group);
            recipe.original.write(buffer);
            buffer.writeItemStack(recipe.result);
        }

    }

}

 

And the serializer

public class ModRecipes {
    public static class Type {
        public static final IRecipeType<BdoCookingRecipe> BDOCOOKING = IRecipeType.register(BdoCooking.MOD_ID + ":bdocooking");
    }

    public static final DeferredRegister<IRecipeSerializer<?>> RECIPE_SERIALIZERS = new DeferredRegister<>(ForgeRegistries.RECIPE_SERIALIZERS, BdoCooking.MOD_ID);

    public static final RegistryObject<IRecipeSerializer<BdoCookingRecipe>> BDOCOOKING = RECIPE_SERIALIZERS.register("bdocooking", () -> (new BdoCookingRecipe.Serializer()));
}

 

What changes do I need to make to ensure that this recipe will be shapeless and support 5 inputs?

Thanks for any help and suggestions.
