Quick question. I have an item that has a reagent requirment. The items works fine if the reagent requirment is set to one of the item. I am trying to make it that you need more than one of the reagent. So you want to use the item, thats fine however you need at least 2 of the reagent in your inventory, and if you have at least two in the inventory it will proceed with using the item and then consume the two reagents. All that works. Here is my consume function:

private void consumeReagent(ItemStack stack, World worldIn, EntityPlayer entityLiving) { entityLiving.inventory.clearMatchingItems(eAngelusItems.mystalDust, -1, dustRequirement, null); }

 

dustRequirment is currenty a configurable option set to default at two so it consumes two of the items. The check works like this: 

   

@Override
    public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn)
    {
        ItemStack itemStack = playerIn.getHeldItem(handIn);
        boolean hasReagent = playerIn.inventory.hasItemStack(new ItemStack(eAngelusItems.mystalDust));
            if (hasReagent)
            {
                itemStack.damageItem(1, playerIn);
                playerIn.addPotionEffect(new PotionEffect(Potion.getPotionFromResourceLocation("speed"), 400, 4));
                this.consumeReagent(itemStack, worldIn, playerIn);
            } else {
                ChatUtil.sendNoSpam(playerIn, "\u00A74Mystal Dust is a required Catalyst.");
            }
        return  new ActionResult(EnumActionResult.SUCCESS, playerIn.getHeldItem(handIn));
    }

 

Now normally to check the contents of the inventory i would do this: 

if (playerIn.inventory.hasItemStack(new ItemStack(eAngelusItems.mystalDust)))

But i can't figure out how to check if you have at least two of those items. I am sure it is a function somwhere and I just haven't found it yet.

There is no such method, you need to write it yourself. But it should be pretty straightforward, just loop through the inventory and sum all the stack sizes of items matching your criteria. When you found at least two, you can stop searching.

Yeah, figured so and made one. Just wanted to ask anyway in case something changed. Thanks.
