[1.8.9][SOLVED] Make a recipe that needs more than 1 Item unit on the same slot

[Major Squirrel]

Good evening,

 

Everything is in the title. I tried myself using new ItemStack(Items.something, 3) for testing, it obviously didn't work.

 

According to a Wuppy's tutorial, it seems that it isn't possible to do it. But his tutorial is dated from 2014, and I'd like to know if anyone had achieved it for 1.8.9 ?

You would need to write your own crafting bench and your own recipes.

 

I have a machine that takes in stacks of size 8 and produces a single-size result, for example.

Thanks Draco18s for the tip. Is there any way to make it craftable from a basic workbench ?

 

(If not, I would suppose that the "1 unit" consumption is coded in the workbench directly)

I haven't looked, but pretty sure that the vanilla workbench has it hardcoded to only use one of each.  There are custom IRecipe implementations, but while you could make the output not show up unless 3 of the item were in a stack, I don't think it would actually use all three.

 

Here's what my block does, it's very single-purpose, pro-automation.

The stack-of-eight is actually an efficiency improvement over the workbench crafting recipe (uses 9).

(And the second input slot is just a buffer area, like the hopper)

Thank you for the reference. I will keep this link to take a look at implementation !

 

In 1.8.9 you can actually make this work with a bit of a hack.

Make a custom recipe class (implementing IRecipe). In the matches method you can check if the stack sizes of the supplied crafting inventory are sufficient. Then in the

getRemainingItems

method decrease the stacks in the crafting inventory by

n - 1

each (n being the total amount needed in that slot). -1 because vanilla will also still consume 1 Item. Once you have done that call

ForgeHooks.defaultRecipeGetRemainingItems

and return the result.

 

I didn't think about that ! Thank you too.

 

I will mark this as solved since you both gave explanations and ways to implement it !

I think you can do that for custom vanilla crafting table.

You just need to return the right stuff in getRemainingItems in ur custom IRecipe
