So I am trying to make a recipe class that lets you attach 'spirits' to an item, and you can attach multiple spirits with different metadata, etc. But, for some reason it only works when the item you are attaching to is in a certain slot. I've tried everything I can think of, can anyone help out?

 

CLASS:

 

 

package yorkeMC.alfhomancy.api.crafting;

 

import java.util.ArrayList;

import java.util.List;

 

import javax.annotation.Nonnull;

 

import net.minecraft.entity.item.EntityItem;

import net.minecraft.inventory.InventoryCrafting;

import net.minecraft.item.ItemStack;

import net.minecraft.item.crafting.IRecipe;

import net.minecraft.world.World;

import yorkeMC.alfhomancy.common.items.ItemElvenSpirit;

import yorkeMC.alfhomancy.common.items.ItemWings;

import yorkeMC.alfhomancy.common.registry.ItemRegistry;

 

public class ISpiritRecipe implements IRecipe

{

@Override

public boolean matches(InventoryCrafting inv, World w)

{

boolean foundSpirit = false;

boolean foundItem = false;

 

for (int i = 0; i < inv.getSizeInventory(); i++)

{

ItemStack stack = inv.getStackInSlot(i);

 

if (stack != null)

{

if (stack.getItem() == ItemRegistry.ItemElvenSpirit && !foundSpirit) foundSpirit = true;

 

else if (!foundItem)

{

if (stack.getItem() == ItemRegistry.ItemWings) foundItem = true;

else return false;

}

}

}

return foundSpirit && foundItem;

}

 

@Override

public ItemStack getCraftingResult(InventoryCrafting inv)

{

ItemStack wings = null;

ItemStack copy = null;

ItemStack spirit = null;

List<ItemStack> items = new ArrayList<ItemStack>();

 

for (int a = 0; a < inv.getSizeInventory(); a++)

{

if (inv.getStackInSlot(a) != null)

{

items.add(inv.getStackInSlot(a));

if (items.size() >= 2)

{

for (int i = 0; i < items.size(); i++)

{

if ((items.get(i)).getItem() == ItemRegistry.ItemWings && items.get(i).getItemDamage() != 0)

{

wings = items.get(i);

copy = wings.copy();

}

 

for (int s = 0; s < items.size(); s++)

{

if (items.get(s).getItem() == ItemRegistry.ItemElvenSpirit)

{

spirit = items.get(s);

}

 

for (int go = 0; go < items.size(); go++)

{

if ((wings != null && spirit != null))

{

if (!ItemWings.hasSpirit(wings, spirit.getItemDamage()))

{

ItemWings.addSpirit(copy, spirit.getItemDamage());

}

}

}

}

}

}

}

}

return copy;

}

 

@Override

public int getRecipeSize()

{

return 10;

}

 

@Override

public ItemStack getRecipeOutput()

{

return null;

}

}

Unrelated question: why does your class start with an 'I'?
