Hello, I am JasonIEC, and I am wondering how to make recipes in Scala, or how to have mixed Scala/Java mods.

My specific problem is the fact that Scala doesn't seem to support java.lang.Object arrays.

Any help is appreciated ;)

 

Thanks!

 

Scala's AnyRef is a type alias for java.lang.Object. So to define your recipe, you go:

Array[AnyRef](/* your stuff comes here.*/)

 

Also @hsgill97, choosing scala is mostly about personal preference, as scala has some really convenient stuff about it. Also you can mix java and scala code so that will not be  a problem.

If my post helped you, please press that "Thank You"-button to show your appreciation.

 

Also if you don't know Java, I would suggest you read the official tutorials by Oracle to get an idea of how to do this. Thanks, and good modding!

 

Also if you haven't, set up a Git repo for your mod not only for convinience but also to make it easier to help you.

Thank you all! I will definitely try these things. Also, I chose Scala because I wanted to try it  :P

 

Edit: The Array[AnyRef]() hasn't worked for me :/

 

Also, the varargs aren't working because it won't let me cast java.lang.Character to java.lang.Object
