[1.12.2] Changing the ingredients of a vanilla crafting recipe

[Jiro7]

So I want to replace the recipes of furnace and stone tools and make them require a new, more expensive material I created.

 

I managed to remove the recipes by replacing them with a dummy recipe, using a code like this:

public static void removeRecipes() {
			 ForgeRegistry<IRecipe> recipeRegistry = (ForgeRegistry<IRecipe>)ForgeRegistries.RECIPES;
		        @SuppressWarnings("deprecation")
				ArrayList<IRecipe> recipes = Lists.newArrayList(recipeRegistry.getValues());
		        
		        for (IRecipe r : recipes)
	            {
	                ItemStack output = r.getRecipeOutput();
	                if (output.getItem() == Item.getItemFromBlock(Blocks.FURNACE))
	                {
	                    recipeRegistry.remove(r.getRegistryName());
	                    recipeRegistry.register(DummyRecipe.from(r));
	                }
	            }
		}

 

I have also created my own furnaceJ.json file with the new recipe, however this recipe seems to also be overriden by the dummy recipe.

 

I read that the solution is to register my own recipe instead of the dummy one in this line:

recipeRegistry.register(DummyRecipe.from(r));

 

But... how can I do it? My recipe is saved in a .json file, not in a .java file like the Dummy recipe.

 

I know the solution is probably very simple but I just can't see it.

Check if the registry name of the recipe is the vanilla recipe before removing it.

How can I do that? Is there any method for that?

You are already calling it:

 

I know I should be using something like if (r.getRegistryName() == ???)

 

But I don't know how the vanilla recipe is called
