Hello there,

 

I have been using copies of the vanilla FurnaceRecipes class, with additional methods to make use of the ore dictionary, but have always had the problem that the input ItemStack can only have a size of 1, unlike the output which can be as big as wanted - as an example, it seems to be impossible to have 2 sticks processed into 1 wooden plank - only 1 stick is used for the process. Is there an easy modification that can be made to the class to allow for these recipes, such as a modification to the getSmeltingResult or func_151397_a (something which I still don't fully understand anyway) methods?

 

Crusher recipe class if needed:

Thanks in advance for any ideas and help

Bump, and an update:

 

I have changed func_151397_a so that it also checks for the stacksize of the input, as suggested by a friend of mine:

private boolean func_151397_a(ItemStack input, ItemStack expected)
    {
        return expected.getItem() == input.getItem() && expected.stackSize == input.stackSize && (expected.getItemDamage() == 32767 || expected.getItemDamage() == input.getItemDamage());
    }

But all that has caused is only stacks of a size of 1 are processed in the machine.

You need to write your own recipe handler to check for stack sizes.  Furnace recipes don't care how big the stack is.

 

So you'll need a way to check that a recipe is valid (ignoring stack size) and then get how big the input stack size is for the recipe and check that the slot has at least that many items and then remove that many items when it completes.

 

This is how I handled it.  It's likely not the best way, but I was working off of the vanilla furnace's handling.
