Hello. Been learning C# and Unity3D both same time and gotten pretty far, I'm surprised of myself to say the least. But just a simple question, don't hang me for this! <3 Been following some tutorials etc. They use UnityEngine.AI in these tutorials, tried to google like crazy but can't find info, even from this site, so when I try to write up 'Using UnityEngine.AI', VisualStudio says that there is none named liked that. So is it included maybe in UnityEngine and I am just watching obsolete tutorials?
