Creating Own library ...

Hello,
I wanna create functions that people will be able to use them in each C# file, they will have to add the file with the functions and use them as a normal functions. How can I do it? Is there any tutorial for it?
Thanks all for help! !!

Are you saying that you have some utility classes and/or functions that you’d like to share or publish?

If it’s just a single class or function, I’d recommend posting it to these forums and to the wiki.

Is it a large set of classes that act like a library? In Unity, go to “Assets > Export Package…”, select the files you want to include, and “Export…”.
