The mod I am making has a machine that is basically a multistep furnace.

That is, it has 8 slots - 4 input (where you can place items) and 4 output, one corresponding to each input slot and therefore each "stage" of the operation.

Basically, I want to be able to have ore go in input #1, turn into dust in output #1, then that dust can be placed in input #2, which goes into output #2 as slurry, then that goes into input #3, turning into ore solutions in output #3, which can be placed in input#4, which turns into ore flakes in output #4.

 

I want to make sure this order is preserved; I do not want the slots to be functionally interchangeable - I do not want one slot's recipes/item inputs being usable by another.

Is there a way to do this?

 

Also worth noting, the input and output items are all the same ID, differentiated by metadata, which is causing me problems for the addSmelting function (which does not seem to be metadata-sensitive).

 

To make visualizing the process easier, here is the GUI image:

 

 

EDIT: I got it working by sort of jury-rigging my own Slot objects, which can only have the "valid" items placed in them.

I did work on a Furnace workbench and i did made a 3 slot input into 1 slot output.

 

Idea is make in a basic furnace. The basic furnace Checks if the recipe is correct.

When its true he starts to work.

 

Do this 4 times and you have your for step furnace!

For your 3->1 example, yes, but not for mine, because additional code is required to ensure the order of steps is preserved. Without taking steps to do that, it would be possible to put input#4 into slot #2 and get output#4 (or even output #2!).

each input would need it's own slot that can only have certain items in it. I made something like that in my mod. https://github.com/code-lyoko-modding/CodeLyokoMod/tree/master/lyoko/slots

That is what I ended up doing, yes.
