Hey, I am working on crafting expansion which will allow to define byproducts in recipes. Work is almost done, but I would like to have your thoughts on existing recipes, or new ones, which can use such feature, so I can include these in initial release. Here is an example (this one is for fun and will not be in release) ![](https://dl.dropboxusercontent.com/u/18187861/toothpick.PNG) [ul][li]Recipe can have more than one byproduct.[/li] [li]Byproduct can have charge multiplier defined - useful for comestibles and ammo, which have charges defined, you can multiply the amount of charges this way[/li] [li]Byproduct can have amount specified - like in toothpick example above[/li][/ul] If you have any suggestion, please share 🙂 ---

Looks awesome! Although I am not sure I get the charge-multiplier-thingy. ---

[quote=“Snaaty, post:2, topic:6923”]Looks awesome! Although I am not sure I get the charge-multiplier-thingy.[/quote] Comestibles have defined charges - which is quantity in which it is crafted, bread is defined with 8 charges, so it has 8 uses - you can eat 8 loafs, one per each eat action. Similarly, ammo is defined with count, .223 Remington is crafted in batches of 40. Multiplier multiple, how many charges / count you craft per one crafting action. Currently, it is used only in brewing (or I didn’t find any other instance where it is used). For example, whiskey wort is defined with 7 charges - like rest of the alcohol. Author of brewing (guess it was him) used multiplier 3 in recipe, so that crafting can make 21 charges in one go, which is enough to fill one glass bottle. I just added same possibility to byproduct. ---

This looks incredible! 😃 Good luck with this project, if you manage to pull it off it will make it into the main-line without a doubt 😃 …This will be game changing 🙂 ---

It does work already and it most likely ends up in the mainline. I am not the one who will decide that, but KA101 and Kevin are very helpful and supportive. Though I still need to do more testing and add some more recipes that fit in, changes will hopefully be in experimental version in a few days. I believe it will be especially useful for your chemical stuff, like Zireael pointed out already, as in chemical reactions, byproducts are more of a rule than an exception. ---

It’s about to get merged, unless something breaks in testing. I’ve queued it and am ramping up. Update: Stuff broke, but [this wasn’t one of 'em](https://github.com/CleverRaven/Cataclysm-DDA/pull/8364). Merged. ---
