I'm new to modding and I'm trying to make a brewing recipe that takes an "essence of undeath" and awkward potions to make "ink of innervation" items, but when I try this in-game I can't even place the essence in the brewing stand. What am I doing wrong?
 

public class ModRecipes
{
	public static void Init() {
		BrewingRecipeRegistry.addRecipe(PotionUtils.addPotionToItemStack(new ItemStack(Items.POTIONITEM), PotionTypes.AWKWARD), new ItemStack(ModItems.ESSENCE_OF_UNDEATH), new ItemStack(ModItems.INK_OF_INNERVATION));
	}
}

 

Where do you call that method?

Oh, whoops. I forgot to initialize ModRecipes in main.java.... thanks for reminding me:

@EventHandler
	public static void init(FMLInitializationEvent  event)
	{
		ModRecipes.Init();
	}

Now everything ALMOST works perfectly; except now when I brew the recipe in-game, every single type of potion will work in the recipe, not just awkward potions. Any ideas how to fix this?

I think the recipe is only checking for item ID, not for NBT, so it will always accept any potion. You will probably have to create new type of brewing recipe.

Ok so I found a previous thread about this same issue, except the person didn't explicitly state in code how to remedy this issue.

He said he "extended AbstractBrewingRecipe and overrode isInput so the stack comparison is nbt and meta data sensitive".

 

@Override
    public boolean isInput(@Nonnull ItemStack stack)
    {
        return OreDictionary.itemMatches(this.getInput(), stack, false);
    }

This is the code in question. How would I manipulate this to allow nbt/meta data?

Alright, so I added some code to isInput to account for nbt data... except it didn't change anything. In fact, randomly switching around the boolean values for isIngredient and isInput doesn't cause any changes whatsoever for the recipe in-game. Maybe I'm just a clueless noob, but i feel thoroughly stumped right now. Does anyone know what I'm doing wrong?

Randomly making your classes extend other classes won't do you any good. Your recipe is the one that needs to extend the AbstractBrewingRecipe, not some other random class.

Ok then, I made a new class for my recipe. Although the code is essentially the same, and nothing new happened, so I don't see what the point of that was.

 

package com.ScootMcShoot.scootsnecromancymod.init;

import javax.annotation.Nonnull;

import net.minecraft.init.Items;
import net.minecraft.init.PotionTypes;
import net.minecraft.item.ItemStack;
import net.minecraft.potion.PotionUtils;
import net.minecraftforge.common.brewing.AbstractBrewingRecipe;
import net.minecraftforge.common.brewing.BrewingRecipeRegistry;
import net.minecraftforge.oredict.OreDictionary;

public class BrewingRecipeInk extends AbstractBrewingRecipe
{

	protected BrewingRecipeInk(ItemStack input, Object ingredient, ItemStack output) {
		super(input, ingredient, output);
	}

	public static void init() 
	{
		BrewingRecipeRegistry.addRecipe(PotionUtils.addPotionToItemStack(new ItemStack(Items.POTIONITEM), PotionTypes.AWKWARD), new ItemStack(ModItems.ESSENCE_OF_UNDEATH), new ItemStack(ModItems.INK_OF_INNERVATION));
	}

	@Override
	public boolean isIngredient(ItemStack ingredient) {
		return false;
	}
	
	@Override
    public boolean isInput(@Nonnull ItemStack stack)
    {
		if (stack.getTagCompound() == (PotionUtils.addPotionToItemStack(new ItemStack(Items.POTIONITEM), PotionTypes.AWKWARD)).getTagCompound())
			return OreDictionary.itemMatches(this.getInput(), stack, false);
		else
			return false;
    }
}

 

If you could be as specific as possible with what I need to do that would be greatly appreciated.

All you did was rename ModRecipes to BrewingRecipeInk(efectively). That does nothing.

You still have the same issue. You can have a million and one classes all extending AbstractBrewingRecipe but if the recipe being registered is not an instance of any of them then they do nothing.

The recipe you register needs to be the one that extends AbstractBrewingRecipe, not some random irrelevant class.

How am I supposed to extend 

public static void init() 
	{
		BrewingRecipeRegistry.addRecipe(PotionUtils.addPotionToItemStack(new ItemStack(Items.POTIONITEM), PotionTypes.AWKWARD), new ItemStack(ModItems.ESSENCE_OF_UNDEATH), new ItemStack(ModItems.INK_OF_INNERVATION));
	}

with AbstractBrewingRecipe? All I have is that statement, but it's not a class, and I can't extend it if it's not a class. Therefore I assumed you meant I needed to make a new class for my recipe, but like both of us said, that changes nothing. Please don't repeat what you said again for the third time, that doesn't help me. Thank you for your patience.

What you need to do, is create a new Class, let's say you call it MyCustomRecipe. That class then needs to extend AbstractBrewingRecipe, and override the isIngredient (and in your case, the isInput) methods. Then, instead of doing this:

BrewingRecipeRegistry.addRecipe(PotionUtils.addPotionToItemStack(new ItemStack(Items.POTIONITEM), PotionTypes.AWKWARD), new ItemStack(ModItems.ESSENCE_OF_UNDEATH), new ItemStack(ModItems.INK_OF_INNERVATION));

you do the following:

BrewingRecipeRegistry.addRecipe(MyCustomRecipe);

Doesn't work. There's an error at 

BrewingRecipeRegistry.addRecipe(MyCustomRecipe);

 that says "MyCustomRecipe cannot be resolved to a variable" and it doesn't give me the option to import it.

You need to create a new custom recipe to register...

Yeah, sorry about that, I realize i shouldn't try to answer coding questions when I haven't slept in over 48 hours ^^. Anyways, you need to do what Cadiboo said, instead of my originally proposed 

BrewingRecipeRegistry.addRecipe(MyCustomRecipe);

you need to do

BrewingRecipeRegistry.addRecipe(new MyCustomRecipe(stack1, stack2, stack3));

where stack1-3 are your desired Inputs / Outputs. Again, sorry for any confusion I may have caused

You know, if they write code like that

 and complain about basic syntax errors they should be probably told to go and learn java. Not to be arrogant or anything but if you just throw ready-to-use solutions at them they won't learn and will come back here with a similar problem in a day or so. The purpose of the forums is not to give people code they can just copy-paste without thinking about it.

Oh my god it finally works and I'm so happy. So for some reason the comparison in isInput using the .getCompoundTag() method didn't work, but luckily I found another method .areItemStackTagsEqual() that solves my issue perfectly. Posting my updated code in case anyone else has the same problem.

Thank you so much for your help everyone, I feel like I learned a lot.
