I want to create a reversible recipe (e.g axes). Is there a built-in way to do this or do I just have to create two shaped recipes?

Do you mean something like 'uncrafting'? Then you need to implement your own custom reversible table.

EDIT: Nevermind, you don't need custom table.

First, you should make recipe which gives the most important ingredient.

Then subscribe to the PlayerEvent#ItemCraftedEvent, and give player the rest of the item there.

I mean something like how Axes and Hoes can be crafted inverted to the default recipe (facing left or right).

Ah, then you just need to create a new recipe.

Or you can use custom reflexible IRecipe implementation.

Thank you, I'll see if I can do use the reflexible recipe.

What you want is mirrored recipies. This is a built in feature.

Hi

 

Like Lex says, all vanilla recipes are mirrored automatically.

Normally you have to register your recipe in a special way if you don't want them to be mirrored
