Crafting With Leftovers

[GaryTheGreat]

There's many a crafting system script out there, but what I've trouble finding is the one that lets you set up leftover material after crafting.

For instance, you have 2x Small Potion.
You can craft them together into 1x Big Potion. But you also receive Empty Flask in the process (because you poured one potion into another).

You could also call it a secondary crafting result, but it has to be hidden - Empty Flask is not the goal you're aiming for when you craft, it's just a bonus item on top of your result. So it mustn't be displayed in the crafting window or anything.

I'd say it would be easiest to find a crafting system that you like and then get someone to add that feature to it.

Isn't there some scripts you can both add recipes but also create items by mixing them? You could make the "leftover recipes" be an unclassified recipe

 

[GaryTheGreat]

That would mean I have a recipe that has nothing listed except Empty Flask as a result or what?
I don't quite get the idea, could you elaborate more?

Bump

Do you have a crafting script that you're currently using that you would like this to be a feature of?

This one looks simple enough.

This script is an addon for Coelocanth's Item Crafting System. It allows you to
set other items, weapons and armours to be gained from crafting a particular
item. They will not appear in the ingredient or results lists.

Use the following in an item's notes:

  <craft extra: i7>           this would give 1x item 7
  <craft extra: w2:9>         this would give 9x weapon 2
 
  <craft break extra: w8:3>   this would give 3x weapon 8
  <craft break extra: a1>     this would give 1x armour 1
 
  where i is for item, w is for weapon and a is for armour.
