Good day,

I made a fully functional double input furnace. Except now I want to make it so it creates random output. I suppose that I will need to make the output slot have maximum stack of 1, but in inventory I want for the items to stack.

So I am asking for your help:

How do I make the output slot have maximum stack of 1 and how to create the random output?

You want the results to be different (and random) and stack?

 

These two statements do not go together.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.

He's asking how to limit the stack size to 1, so it wouldn't be stackable in the slot, while vanilla stacking behavior would still be in effect in the normal player inventory.

 

Since it's a furnace, you should have a TileEntity with this method in it already (assuming you implemented ISidedInventory, which you should have if you're making a furnace):

@Override
public int getInventoryStackLimit() {
return 64;
}

Do I need to say more?  :P

 

For the random output, how are you storing your recipes? Does it matter what the inputs are at all, or should it be totally random? If it's totally random, then one option would be to make a List of ItemStacks and use list.get(rand.nextInt(list.size())) to return a random stack from within the list.

Tried that, it limits all the slots (even the coal one)

Basicly I want to not stack it in the output slot, but stack it outside the slot (in inventory)

EDIT: And about those recipes, I'll show you an example:

Slot 1 = Item.arrow

Slot 2 = Item.bone

Output slot = 25% Item.ingotGold, 10% Item.ingotGold, 5% Item.diamond, 60% Block.cobblestone

And becouse the item couldn't stack, I want to limit only the output slot to 1 item at a time.

 

My recipes look like this:

private static ItemStack getOutput(int i, int j)
	{
		if (i == Elementum.uraniumItem.itemID && j == Elementum.ironCell.itemID)
		{
			return new ItemStack(Elementum.uraniumCell, 1);
		}
		return null;
	}

Then it's a matter of just not processing input when the output slot isn't null, and the disallowing of the player putting items in the output slot (which you can do in the Container).

I really recommend not making it hardcoded and creating a recipe list instead (unless the random items are the same for every input item off course).

So create a custom output slot with this method:

@Override
public int getSlotStackLimit() {
   return 1;
}

When adding slots to your Container, be sure to use your custom slot only for your output.

 

Look through the Slot class to see the other methods mentioned by MineMaarten - you will need them to prevent the player from putting things into the slot.

 

From your recipe code, it didn't look random at all. It's still a recipe requiring two specific items to return a specific output... I'd suggest you take a good look at the vanilla FurnaceRecipes class. Do you see where it returns the smelting result? Well, instead of returning a specific ItemStack, store a custom int or whatever in the HashMap that tells you what random list to pull the item from:

// I'll modify the vanilla for 2 itemstacks
public ItemStack getSmeltingResult(ItemStack item1, ItemStack item2) 
    {
        if (item1 == null || item2 == null) { return null; }

        int randomList = -1;

        if (metaSmeltingList.containsKey(Arrays.asList(item1.itemID, item1.getItemDamage(), item2.itemID, item2.getItemDamage()))
        randomList = metaSmeltingList.get(Arrays.asList(item1.itemID, item1.getItemDamage(), item2.itemID, item2.getItemDamage()));
        
        ItemStack output = null;

        switch(randomList) {
        case 1: // you put in an arrow and a stick or whatever
             // output = select from random list one containing gold, cobblestone, etc.
        case 2: // you put in dirt and gunpowder or whatever
             // output = select from random list two
        default: // for value of -1 or other unhandled cases

        return output;
       }
}

Something of that nature should work.

Alright. Fixed it now! Thank you everyone for your help :)

Used:

private static ItemStack getOutput(int i, int j)
	{
		if (i == Item.clay.itemID && j == Item.paper.itemID)
		{
			Random rand = new Random();
			int randNum = rand.nextInt(10);
			if(randNum == 1){
				return new ItemStack(Item.bone, 1);
			}
			if(randNum == 2){
				return new ItemStack(Item.stick, 1);
			}
			else{
			return new ItemStack(Item.arrow, 1);
			}
		}
		return null;
	}
