How do I call functions in a DLL from Unity in C#? I have an example C# program that doesn't run in Unity but they just add a "using libraryName;" at the top of a file and it works.
I've placed the DLL in Assets\Plugins and as far as I can tell Unity knows it's there.
I've seen mention of adding "[DllImport ("libraryName")]" above function defines, but I can't figure out how to call functions in the library and have it actually work.
