Hi there,

 

I've got a few questions regarding recipes in Forge 1.12.2:

 

1. What 'types' does forge come with besides the normal minecraft:shaped_recipe and minecraft:smelting stuff.
2. How can one register his own type.
3. How can I create a recipe which returns multiply different items, for example an emtpy bucket and an apple (in this case a full bucket was provided) or an apple and a dirt block.

 

Thx in advance.

Bektor

You need a _factories.json file:

Buckets of liquids automatically return an empty bucket due to the Container Item mechanics. This has nothing to do with the recipe.

So what exaclty is a factory in Forge and how does it work?

A "factory" in the programming sense is a class and code that constructs an object of another class.

https://en.wikipedia.org/wiki/Factory_(object-oriented_programming)

 

The _factories.json file points the string key name from the type to a class reference. Specifically the factory that has a known constructor and input method that the JSON segment needing to be deserialized can be passed to in order to construct the unknown object type:

Choonster also has a nice set of simple test classes that demonstrate various solutions to common questions about custom recipes: https://github.com/Choonster-Minecraft-Mods/TestMod3/tree/1.12.2/src/main/java/choonster/testmod3/crafting.  See the assets folder for json files like _factories.json ...

But what about custom items?

 

I'm also wondering if it is possible to define multiply recipes for the same item and how this should be done?

Override hasContainerItem and getContainerItem :|

Probably not. I mean how would that work, a bucket of milk returns a glass bottle, but a bucket of water returns a bucket?

Well: Crafting a bed might need wool, but you might also use stone.

Different recipe, same result.

That's...not even related to container items...
