Can a Unity package be developed in C++ or does it have to be C# or Java?
Where can I obtain docs on writing a Unity package?
Maybe you’re talking about plugins? A Unity package is made by selecting assets and then doing Assets → Export Package; it doesn’t involve programming languages at all.

OK, maybe i am talking about plug-ins. I’m talking about the ability to add new features to uNity that are not there by third party developers. Much like the Terrain Toolkit does!
Only Unity Pro can use C++ plugins, so I wouldn’t recommend it. They’re rarely needed anyway, and would make development significantly harder than just using JS or C# (you’d need JS or C# scripts anyway to actually interface with the engine).
