[Unanswered]Depleting Items After Crafting [1.5_01][2.12]

I am currently working on my first mod, yet I am stuck at one point. Of course, I am having some troubles, so I decided to come here and ask yet another question. As I don't want to give away any details of my mod, I will use different name variables.

With my current mod, I have a crafting recipe in which I am wanting one of the items to be given back, except depleted. So, what I did is I looked in the Items.java file to look up the properties for buckets (as they do something like this in cakes). I saw that the different kinds of filled buckets had a unique property on the end, .setContainerItem(bucketEmpty). I figured that this was what I was looking for, so I went straight in for it.

In my mod_MyModName.java, I added this code:

Code:

   public static final Item itemA = new Item(4206).setContainerItem(itemB).setItemName("itemA");
   public static final Item itemB = new Item(4207).setContainerItem(itemC).setItemName("itemB");
   public static final Item itemC = new Item(4208).setContainerItem(itemD).setItemName("itemC");
   public static final Item itemD = new Item(4209).setContainerItem(itemE).setItemName("itemD");
        public static final Item itemE = new Item(4210).setItemName("itemE");


I also make the separate classes for each of these items, I make the in game names, the crafting recipes, and I make the textures for the items. I recompile, reobfuscate, no errors. I put the files into my minecraft.jar, along with my textures. It black-screens. I have a look at the ModLoader.txt file in my .Minecraft folder, and it shows me the errors that came up.

Code:

The main thing that caught my eye here was the line:

Code:

java.lang.IllegalArgumentException: Max stack size must be 1 for items with crafting results

After looking around again in the Item.java file, I found this:

Code:

public Item setContainerItem(Item item)
    {
        if(maxStackSize > 1)
        {
            throw new IllegalArgumentException("Max stack size must be 1 for items with crafting results");
        } else
        {
            containerItem = item;
            return this;
        }
    }

I figured that I needed to change the maxStackSize of my new items to 1. I looked, and this was already true for all of them. I tried setting the result in my crafting recipe to a stack of one, the other reagents to the recipe as one, yet my game still crashed. I can't figure this out, so I was thinking that this may have something to do with ModLoader. I have been lost on this for the majority of this day, so any help would be appreciated. Thanks!

Well, I've figured out the crashing problem, but I still have one problem - I am not getting the items back as I am expecting. With the .setContainerItem function, I was expecting to get itemB in the crafting table when I use a crafting recipe with itemA. When I do such a recipe, I only get the crafting result, not the container item. Here is my code again, with a bit more editing and polish (but still with other name variables).

Code:

public static final Item itemA = new ItemToolType(4206).setContainerItem(mod_MyModName.itemB).setItemName("itemA");
public static final Item itemB = new ItemToolType(4207).setContainerItem(mod_MyModName.itemC).setItemName("itemB");
public static final Item itemC = new ItemToolType(4208).setContainerItem(mod_MyModName.itemD).setItemName("itemC");
public static final Item itemD = new ItemToolType(4209).setContainerItem(mod_MyModName.itemE).setItemName("itemD");
public static final Item itemE = new ItemE(4210).setItemName("itemE");

What I've done here is set all (but E) as a single item-type class to save space, as they all do the same thing, just with different textures. For the .setContainerItem function, I actually had it like this the first time, I just mistyped the code for the post. If I tried to do it without the "mod_MyModName.", it wouldn't recompile. itemE has it's own class because it is a bit different from the rest of the items.

Also, here is my ItemToolType class:

Code:

package net.minecraft.src;

public class ItemToolType extends Item
{
   public ItemToolType (int i)
   {
      super(i);
      maxStackSize = 1;
   }
}


If you need any more information, please post. I am really getting frustrated with this problem.

Thanks for the help!

have a small test, remove all itemB to itemD and set itemA
.setContainerItem(mod_MyModName.itemE)

Code:

public static final Item itemA = new ItemToolType(4206).setContainerItem(mod_MyModName.itemE).setItemName("itemA");

if it doesnt work, tell us

Did you want me to literally remove the items, or just take them out of the .setContainerItem train? I just put in the code you gave me (replacing the variables, of course), but left everything else the same. I also tried doing:

Code:

public static final Item itemA = new ItemToolType(4206).setContainerItem(mod_MyModName.itemB).setItemName("itemA");
public static final Item itemB = new ItemToolType(4207).setItemName("itemB");

Yet this didn't work, either. Both methods recompiled/reobfuscated, but the item still just disappeared after crafting.

I then tried putting itemsB-D in a block comment in all instances where they appeared, yet nothing appeared in my inventory after crafting.

Thanks again for your help!

So, does nobody know how to fix this then? Any ideas on what I could try to do instead to have a similar effect? This is still quite frustrating me and, though I can still develop the mod, I can't release it until I have fixed this, or found an alternative.
